DETAILED DESCRIPTION OF THE INVENTION
    [006] In the following, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a portable electronic device 1, according to an embodiment of the present invention, showing the front surface of the electronic device 1 seen diagonally. FIG. 2 is a front view of the electronic device 1. FIG. 3 is a perspective view of the electronic device 1, showing the rear surface of the electronic device 1 viewed diagonally. FIG. 4 is a rear view of the electronic device 1. FIG. 5 is a bottom view of electronic device 1. FIG. 6 is a top view of electronic device 1. FIG. 7 is a view of the right side of the electronic device 1. FIG. 8 is a view of the left side of electronic device 1. FIG. 9 and 10 are diagrams illustrating a way of holding electronic device 1 by a user. Specifically, FIG. 9 shows the front surface of the electronic device 1 to be held by a user, and FIG. 10 shows the rear surface of the electronic device 1 to be held by a user.
    [007] In the following description, the direction indicated by XI-X2 is defined as a direction from left to right in these diagrams, the direction indicated by Y1-Y2 is defined with a direction from top to bottom.
    [008] In addition, an “underside (bottom, below)” of the electronic device 1 refers to the side towards a user holding the electronic device 1, and the “upper side (upper, above)” of the electronic device 1 refers to the opposite side of the “bottom side”.
    [009] Electronic device 1 is, for example, a PDA, and so on. The electronic device 1 has a function of reproducing sound, a function of producing mobile image, a function of communication via radio or by wire, or the like. As shown in FIGS. 1 and 2 the electronic device 1 has a substantially rectangular display area provided over and positioned substantially in the center of the front surface thereof. The electronic device 1 has IR safe parts, 1L formed on the left and right side of the display area 2, respectively, which the user can hold with his hands. According to an embodiment, when using the electronic device 1 the user holds the IR parts, 1L between his thumbs and middle fingers or others, in order to hold the electronic device 1 (see FIGS. 9 and 10).
    [00101 Electronic device 1 has a shape that is long from left to right. As shown in FIG. 2, the left and right edges of the electronic device 1 (i.e., the edges of the parts to be held IR, 1L) are substantially semicircular in the front view of the electronic device 1, and thus, the electronic device 1 has a surface curved on the right side 11R and a curved surface on the left side 11L. That is, the electronic device 1 has a substantially round shape that is long from left to right in front view.
    [0011] As shown in FIGS. 9 and 10, in many cases, the user places his index fingers along the surface of the right side 11R (the surface of the right side of the front housing 11 to be described later) and of the surface of the left side 11L (the surface of the side front housing 11). Note that a rear touch panel 21 is provided on the rear surface of the electronic device 1 (see FIG. 4), to be described later. The fingers placed along the side surfaces HR, 11L are moderately folded as the surface of the right side 11R and the surface of the left side 11L of the electronic device 1 are curved. Consequently, a user can more easily operate the rear touch panel 21 with his finger (for example, the middle finger) placed on the rear surface, while holding the IR parts, 1L, compared to a case in which the surface on the right side 11R and the left side surface 11L are flat surfaces extending from top to bottom. That is, a user can easily remove his finger to the right or left of the rear touch panel 21, and he can also extend his finger to the rear touch panel 21.
    [0012] The display area 2 is provided with a display device and a touch panel (such as a panel in the position of an input device) arranged over the display device. The display device is, for example, a liquid crystal display device, a plasma display device, an organic EL display device, a field emission display device, or the like. The touch panel is, for example, an electrostatic capacity type touch panel. In this example, a front cover panel 10 is attached on the outermost surface of the touch panel, covering substantially the entire front surface of the electronic device 1. Display area 2, defined in front cover panel 10, is flush with the area surrounding display area 2 (that is, no step is formed between the boundary of display area 2 and the surrounding area). When using electronic device 1, a game image, a mobile image, a static image (for example, a photograph, a model, a menu image showing a list of items selectable by the user), and so on, are shown in display area 2. A user can select a desired item and move an object shown in the game image by touching display area 2 with his finger. Note that a touch panel is not limited to a type of electrostatic capacity and can be, for example, instead, a type of resistive film.
    [0013] Electronic device 1 includes a housing accommodating a battery (not shown), a circuit board (not shown) where a CPU (Central Processing Unit) or similar is mounted. As shown in FIG. 7, the housing in this example includes a front housing i and a rear housing 12. Front housing 11 is like a box with its rear surface open. The front housing 11 covers the front side of the rear housing 12, and is attached to the rear housing 12. In this example, the front housing ile rear housing 12 are fixed to each other, using a plurality of screws 17, provided on the outer circumferential part of it (see FIG. 4). The circuit board, described above or otherwise, is placed in the enclosed space by the front housing and the rear housing 12. Housings 11, 12 are made of, for example, resin.
    [0014] As shown in FIG. 2, the front cover panel 10 constituting the front surface of the electronic device 1 has an external shape substantially identical to that of the electronic device 1, and is attached to the front surface of the front housing 11.0 display device and the touch panel provided for the display area 2 are arranged on the rear side of the front cover panel 10. For example, an opening corresponding to display area 2 is formed in the front housing 11, and the display device and touch panel are placed in the opening of the front housing 11
    [0015] As shown in FIGS. 1 and 2, the electronic device 1 includes a plurality of operational members provided on the parts to be safe IR, 1L, projecting from the front surface of the electronic device 1 and available for operation by the user. Specifically, the electronic device 1 in this example includes an operational rod 3R provided on the part to be held on the right IR and an operational rod 3L provided on the part to be held on the left 1L, as the operational members defined in the claims. Operational poles 3R, 3L are positioned and projected from the front surface of the front cover panel 10 (see FIGS. 7 and 8). The heads of the 3R, 3L operating rods are formed in a disk shape, and each 3R, 3L operating rod has a bar (rod) extending from the head thereof towards the inside of the electronic device 1. The rod of each rod Operational 3R, 3L protrudes forward from the front surface of the electronic device 1. Each operating rod 3R, 3L can be tilted in radial directions around the rod. In other words, each 3R, 3L operating rod can be tilted towards any position in the circumferential direction around the rod. In another embodiment for use, each 3R, 3L operating stick is an analog stick and therefore produces a signal according to the direction in which the 3R, 3L operating stick is tilted and the angle of inclination. Note that, however, the movement of the 3R, 3L operating rod is not limited to the movements described above, and the 3R, 3L operating rods can be slidably supported in radial directions.
    [0016] As shown in FIG.2, the 4R buttons are still provided on the part to be held right IR. The 4R buttons are positioned on the front surface of the electronic device 1. The 4R buttons include a plurality of (specifically 4) buttons 4a, 4b, 4c and 4d, which are positioned on the respective cross-shaped ends. Buttons 4a, 4b, 4c and 4d protrude from the front surface of electronic device 1 (see FIG. 7). In addition, a 4L directive key is provided on the part to be held to the left 1L. The directive key 4L has a plurality of (specifically 4) convex portions that together form a cross shape as a whole. The directive key 4L is also positioned on the surface of the electronic device 1. The convex portions constituting the directive key 4L are projected from the front surface of the electronic device 1 (see FIG.8). Openings 10R, 10L are formed in the respective right and left parts of the front cover panel 10. The opening 10R is formed in such a way that the inner edge of the same surrounds the area where the operational rod 3R and buttons 4R are located, and similarly, the opening 10L is formed in such a way that the inner edge of the same surrounds the area where the operating stick 3L and the directive key 4L are located.
    [0017] As shown in FIG.2, the 4R buttons and the 4L directive key are positioned higher and farther out in the left to right direction than the 3R, 3L operational rods, respectively. That is, the central portion between the 4R buttons is positioned more to the right side than the 3R right operating stick. The central position between the 4L directive switch is positioned more to the left side than the left 3L operating stick
    [0018] As shown in FIG. 9, in many cases, the user places his thumbs on the 3R, 3L operating sticks and middle or similar fingers on the rear surface of the electronic device 1 (the rear surface of the parts to be held 1R, 1L) to thereby hold the parts 1R, 1L. Then, when using electronic device 1, a user moves his thumb diagonally towards the 4R buttons or the 4L directive key when necessary. Because the 4R buttons and the 4L directive key are positioned diagonally from the 3R, 3L operating poles, a user can easily move their thumbs towards the 4R buttons and the 4L directive key.
    [0019] As shown in FIG.2, the positions of the operational rods 3R, 3L, buttons 4R and directive key 4L are shifted upwards vertically with a whole on the front surface of the electronic device 1. That is, the distance from the center of each operating stick 3R, 3L to the bottom edge of the front surface of the electronic device 1 is wider than the distance from the center of the 4R buttons or the 4L direction switch to the top edge of the front surface of the electronic device 1. Therefore, the center of gravity of the electronic device 1 is positioned close to a user, compared to an arrangement in which the operational rods 3R, 3L, the buttons 4R, and the directive key 4L are descended vertically, and which allows the user to stably hold the device electronic 1.
    [0020] As shown in FIG. 1 or 2, a plurality of (three in this example) buttons 6a, 6b, 6c are further provided on the front surface of the electronic device 1. Buttons 6a, 6b, 6c are less used when running a software application on the device electronic 1 (for example, when playing a game) compared to the 3R, 3L operating sticks described above, the 4R buttons and the 4L directive switch. Button 6a is, for example, a home button to return an image shown in display area 2 to the initial image. Buttons 6b, 6c are, for example, a selection button to select an item shown in display area 2, a start button to start a software application run, and so on. The buttons 6a, 6b, 6c can have a built-in light emission such as an LED (light emitting diode) or the like. The light emitting element can be used to alert a user to the status of electronic device 1 (power on / off, receiving data via radio communication function)
    [0021] As shown in FIG.2, the buttons 6a, 6b, 6c are positioned below the operational rods 3R, 3L. In detail, button 6a is positioned below operating stick 3L, while buttons 6b, 6c are positioned below operating stick 3R, being arranged side by side in the direction from left to right. The surface of the buttons 6a, 6b, 6c is lower in height from the front surface than the upper surface of the 3R, 3L operating rods. This arrangement can prevent a wrong touch of buttons 6a, 6b, 6c by a user's finger, while the user is operating the respective 3R, 3L operating stick. In this example, the surfaces of the buttons 6a, 6b, 6c are flush with the front surface (the surface of the front cover panel 10) of the electronic device 1.
    [0022] As shown in FIG 2, the buttons described above, provided on the front surface of the electronic device 1, are all positioned in a different area than the top and bottom side of the display area 2. Specifically, in this example , the 3R, 3L operating rods, the 4R buttons and the 4L directive switch are positioned from the right to the left of the display area 2. The left button 6a is positioned away to the right from the direct edge of the display area 2. With this positioning, a user can avoid mistakenly touching any button provided on the front surface with his finger by moving the finger up and down over the display area 2 (for example, when scrolling an image).
    [0023] As shown in FIG.2, a flat surface (i.e., a surface without concave or convexity, hereinafter referred to as the upper flat surface) 10a, which continues from the surface of the display area area 2, is formed above the area where display area 2 is located. In addition, a flat surface (ie, a surface with no concave or convexity, hereinafter referred to as the lower flat surface) 10b, continued from the surface of the display area area of 2, is formed further below the area where the area Display 2 is located. The top flat surface 10a and the bottom flat surface 10b allow the user to smoothly move their finger up and down in the display area 2. Note that the top flat surface 10a and the bottom flat surface 10b reach the top and bottom edges the front surface of the electronic device 1, respectively, and has a width from left to right greater than that of the display area 2.
    [0024] As shown in FIGS. 7 and 8, the upper flat surface 10a includes an inclined surface 10c at the highest part thereof. Specifically, the inclined surface 10c extends upwards and is inclined towards the front, so that the upper edge of the inclined surface 10c is flush with the edge of the upper surface 11c of the electronic device 1. Similarly, the lower flat surface 10b includes an inclined surface 10d at the lowest part thereof. The inclined surface 10d extends downwards, being tilted towards the front, so that the edge of the inclined surface 10d is flush with the edge of the lower flat surface 11b of the electronic device 1. This structure prevents the finger from moving widely up and down over the display area 2 to get stuck on the edge of the electronic device 1.
    [0025] As shown in FIG 2, camera 7 is provided on the front surface of electronic device 1. Camera 7 is used, for example, to capture an image of a user holding electronic device 1. The position of camera 7 it is deflected towards one side, in relation to the central line, in the direction from left to right of electronic device 1. In this example, camera 7 is positioned in the part to be held left IR. This arrangement can reduce camera movement 7 when a user holds the portion to be held left IR. In addition, camera 7 is positioned avoiding the display area 2, the upper area (the upper flat surface 10a) and the lower area (the lower flat surface 10b) in addition to the display area 2. This can prevent the camera surface 7 becomes dirty. Note that camera 7 can be positioned on the part to be held left 1L.
    [0026] As shown in FIG. 2, speakers 9R, 9L are provided on the front side of the electronic device 1. The speakers 9R, 9L are arranged on the rear side of the front cover panel 10. A plurality of holes are formed in the front cover panel 10 in positions corresponding to the respective 9R and 9L speaker, so that the sound can be emitted through the holes. Speakers 9R, 9L are positioned avoiding the display area 2 and the upper area (the upper flat surface 10a) and the lower area (the lower flat surface 10b) in addition to the display area 2. This can prevent holes formed on the 9R 9L speakers to get dirty.
    [0027] The 9R, 9L loudspeakers are also positioned externally from left to right in addition to the 3R, 3L operating rods, respectively. That is, the speaker on the right side 9R is positioned on the right side of the 3R operating stick. The left speaker 9L is positioned on the left side of the 3L operating stick. Because each 3R, 3L operating stick protrudes from the front surface of electronic device 1, unobstruction is ensured between the user's finger placed on the respective 3R, 3L operating stick and the respective 9R, 9L speaker. This can prevent the finger from blocking the sound emitted from the 9F, 9L speakers from spreading.
    [0028] The electronic device 1 has a rear surface which is a surface opposite to the front surface thereof. As shown in FIG. 3 and 4, a rear touch panel 21 (keyboard), i.e., panel-type position input device is provided on the rear surface of electronic device 1. The interrupted line E in FIG. 4 outlines the outer shape of the rear touch panel 21. As outlined by the interrupted line E, the rear touch panel 21 is substantially rectangular.
    [0029] In this example, a rear cover panel 13, which is larger in size than the rear touch panel 21, is placed on the outermost surface of the rear touch panel 21, and the surface of the rear touch panel area 21 is flush with the area surrounding the rear touch panel 21. Furthermore, a hard covering layer is formed on the entire surface of the rear cover panel 13. As shown in FIG. 3 or 4, the outer shape of the rear cover panel 13 corresponds to the shape of the inner area of the curved surfaces (surfaces with the numerals 12L, 12R, 12c, 12d) formed on the outer circumferential part of the rear surface of the electronic device 1. Specifically, the rear cover panel 13 has substantially an ellipse shape that is long in the direction from left to right. The rear cover panel 13 is attached to the outer surface of the rear housing 12. The touch panel 21 is arranged on the inner surface of the rear cover panel 13. For example, an opening is formed in the rear housing 12, and the rear touch 21 is placed in the opening of the rear housing 12. Note that the size of the rear cover panel 13 is not limited to the size described above, and can be a size corresponding to the detection area of the rear touch panel 21. In addition In addition, the rear touch panel 21 is not limited to one type of electrostatic capability, however several types are usable. For example, the rear touch panel 21 may be a type of resistive film.
    [0030] The rear touch panel 21 can be used, for example, as described below. A user can move their finger over the rear touch panel 21 to thereby scroll an image shown in display area 2 (see FIG. 10). In addition, a user can, for example, touch a point on the rear touch panel 21 to thereby select or move an object shown in position, in the display area 2, corresponding to the point.
    [0031] As shown in FIG. 4, the rear touch panel 21 is located in an area (an area surrounded by the interrupted line E) near the center, in the direction from left to right, instead of the opposite rear surface positions of the 3R, 3L operational poles (from here) hereinafter referred to as stick position P). Specifically, in this example, the rear touch panel 21 is positioned closer to the center in the direction from left to right than the parts to be held 1R, 1L, that is, located in the area between parts to be held 1R, 1L left and right. This arrangement prevents a user from mistakenly touching the rear touch panel 21 with his finger while holding the 1R, 1L part (that is, while the user's middle finger is placed on the back surface of the parts to be held 1R, 1L) ( see FIG. 10). In this example, the rear touch panel 21 is positioned between the opposite position of the buttons 4, and the opposite opposition of the directive key 4L.
    [0032] As shown in FIG. 4, the rear touch panel 21 is provided in an area located higher than the pole position P. Most of the time, a user places his thumbs on the 3R, 3L operating sticks and his middle or similar fingers on the rear surface , so as to hold the parts 1R, 1L, as described above (see FIGS. 9 and 10). When the user extends his middle or similar finger while holding the 1R, 1L parts, the user's finger is naturally positioned higher than the P stick position. In this embodiment, because the rear touch panel 21 is located higher than the P stick position, the user can easily operate the rear touch panel 21 with his middle finger while holding the 1R, 1L parts.
    [0033] In this example, a button 14R is provided in the rightmost position of the upper surface 11c, and a button 14L is provided in the leftmost position of the upper surface 11c. Consequently, a user generally rests his thumbs on the respective operating sticks 3R, 3L, and his index fingers on the corners (that is, on buttons 14R, 14L in this example) of electronic device 1 so that the user can immediately press buttons 14R, 14L when needed. Depending on the software application running on the electronic device 1, this positioning can be a basic way of holding the electronic device 1. The area of the rear touch panel 21 is designed in such a way that a user holding the electronic device 1 in this way can operate the rear touch panel 21 with your middle finger. Specifically, as shown in FIG 4, the distance D3 from the straight line Y in the direction from top to bottom, passing through the center of the pole position P and the respective button 14R, 14L, to the respective left / direct edge of the rear touch panel 21, is shorter than the distance D4 from the straight line Y, to the respective left / right edge of the electronic device 1. That is, the left and right edge of the rear touch panel 21 is comparatively close to the P stick position. Furthermore, the upper edge of the rear touch panel 21 is positioned higher than the center between the pole position P and the buttons 14R, 14L. That is, the top edge of the rear touch panel 21 is comparatively close to the buttons 14R, 14L. According to this arrangement, a user can easily touch the rear touch panel 21 with his middle finger while holding the electronic device 1 in a basic manner as described above.
    [0034] As will be described later, the buttons 14R, 14L in this example can be concave, that is, move downwards with respect to the upper surface 11c. The rear touch panel 21 is positioned, from the buttons 14R, 14L, in a diagonally downward direction, and therefore a user can touch the rear touch panel 21 with the index fingers when diagonally moving the index finger on the buttons 14R, 14L in a direction of pressing.
    [0035] In this example, the rear touch panel 21 is offset upwardly vertically with respect to the pole position P. That is, the rear touch panel 21 is located in an expanding area of line L, which is the line extending in the direction from left to right and passing through the pole positions P, towards the upper edge of the rear surface. As a result, the center C1 in the top-down direction of the rear touch panel 21 is positioned higher than the L line. With this rear touch panel arrangement 21, a user does not need to extend his finger placed on the rear surface below . Consequently, a user can stably hold electronic device 1, even when using the rear touch panel 21. Note that the bottom edge of the rear touch panel 21 is positioned slightly below the L line.
    [0036] Note that the area where the rear touch panel 21 is located is not limited to the area described above, and the area can expand, basically, from the L line towards the lower edge of the rear surface. That is, it is advantageous that the rear touch panel 21 is provided with at least one area located higher than the pole position P.
    [0037] As shown in FIG. 4, the area where the rear touch panel 21 is located is deflected towards one side of the top-down direction, relative to the Center C2, in the top-down direction of the electronic device 1. That is, the center Cl in the top-down direction of the rear touch panel 21 is positioned higher than the center C2. Thus, the distance from the diameter to the central part Dl between the lower edge of the rear touch panel 21 and the lower surface 11b of the electronic device 1 is greater than the distance of the diameter of the cavity D2 between the upper edge of the rear touch panel. 21 and the upper surface 11c of the electronic device 1. In other words, the center C2 in the top-down direction of the electronic device 1 is positioned lower than the center C1 in the top-down direction of the rear touch panel 21. Therefore, an area without the rear touch panel 21 is ensured at the bottom of the rear surface of the electronic device 1. The width from top to bottom of the bottom area is greater than the area located higher than the top edge rear touch panel 21. This rear touch panel arrangement 21 can use the bottom of electronic device 1 to arrange electronic components within electronic device 1.
    [0038] As shown in FIG. 3 or 4, a flat surface (hereinafter referred to as the lower flat surface 23a) is formed in an area below the rear touch panel 21. The lower flat surface 23a defines substantially the same plane as that of the surface of the rear touch 21 (rear cover panel surface 13). No projected operating member (e.g., a button) is provided on the lower flat surface 23a. This information basically allows the user to move their finger up and down over the rear touch panel 21. The lower flat surface 23a expands from the bottom edge of the rear touch panel area 21 to the lower part of the rear surface of electronic device 1, and has a width from left to right substantially identical to that of the rear touch panel 21.
    [0039] In an example of electronic device 1, a portion of the surface of the rear cover panel 13 functions as the lower flat surface 23a. In another example, a plate where various information (product name or similar) about electronic device 1 is described, can be attached in the area below the rear touch panel 21, and the plate surface can function as the lower flat surface 23a . That is, the surface of the plate and that of the area of the rear touch panel 21 may constitute the same plane.
    [0040] The width of the rear touch panel 21 is less than that of the display area 2. As a result, the degree of freedom to place components arranged in the electronic device 1 can be increased, while ensuring a sufficient size for the display area. display 2. For example, electronic device 1 includes a plurality of antennas for radio communication. The configuration in which the rear touch panel 21 is less than the display area 2 facilitates an arrangement where the antennas are arranged far from both: the rear touch panel 21 and the touch panel constituting the display area 2 Specifically, the antennas can be easily arranged in positions not overlapping the rear touch panel 21, in the thickness direction (the direction indicated by Z1-Z2 in FIGS. 7 and 8) of electronic device 1, while ensuring sufficient distance between the antenna and the display area 2. This can improve communication stability via antenna.
    [0041] In this example, as shown in FIGS. 2 and 4, the top-to-bottom width of the rear touch panel 21 is smaller than that of the display area 2 and the rear touch panel 21 is offset upwardly vertically from the display area 2. That is, the center Cl, in the top-down direction of the rear touch panel 21, is positioned lower than the center in the top-down direction of the display area 2. Therefore, a component such as an antenna or the like can be accommodated in the bottom of the electronic device 1.
    [0042] However, the left-to-right width of the rear touch panel 21 is substantially the same as that of the display area 2. With this design, the distance between the left-to-right edge of the electronic device 1 and the rear touch panel 21 can be prevented from becoming bigger. As described above, the top-to-bottom width of the rear touch panel 21 is less than that of the display area 2, and the width from left to right of the rear touch panel 21 is the same as that of the display area 2. As a result, the layout of components in the electronic device 1 can be facilitated, and the operability of the rear touch panel 21 can be prevented from deteriorating.
    [0043] The ratio between the width of the rear touch panel 21 and that of the display area 2 is not limited by the above. For example, the left-to-right width of the rear touch panel 21 may be wider than the display area 2. As a result, the left and right edges of the rear touch panel 21 are positioned closer to the respective parts. to be secured 1R, 1L, which, consequently, increases the operability of the rear touch panel 21. In contrast, the width from left to right of the rear touch panel 21 may be smaller than the display area 2. This arrangement facilitates the placement of a component to be arranged within the parts to be secured 1R, 1L.
    [0044] As shown in FIGS. 3 and 4, electronic device 1 has a guide 12f formed on its rear surface to guide the area of the rear touch panel 21. The guide 12f is positioned to the right and left of the rear touch panel 21. In other words , the guide 12f is formed on the respective rear surfaces of the parts to be held 1R, 1L. The user can recognize the rear touch panel area 21 by touching the tab 12f with his finger.
    [0045] The rear touch panel 21 (the surface of the rear cover panel 13) has a flat surface. The surface of the guide 12f has a different style than the surface of the rear touch panel 21. For example, a concave portion and a convex portion are formed on the guide 12f. In detail, the entire guide 12f can be concave or convex, or a plurality of concave or convex portions can be formed on the guide 12f. Alternatively, the guide 12f may have a rougher surface than that of the rear touch panel 21. Furthermore, alternatively, the guide 12f may be made of a different material than the surface of the rear touch panel 21.
    [0046] FIG. 11 is a cross-sectional view of the guide 12f, to be described below, of the electronic device 1, showing a cross-section along the line XI-XI of FIG. 4. As shown in FIG. 11, the rear surface of the electronic device 1 is concave in the guide 12f, in this example. Consequently, a user can easily rest his finger on the guide 12f when not using the rear touch panel 21. The guide 12f is surrounded by the flat surface 13b constituting the same plane with the surface of the rear touch panel 21.
    [0047] As shown in FIG. 4, the rear touch panel 21 is surrounded by the groove 12g formed along the outer edge thereof. In this example, the groove 12g is formed along the top, left and right edges of the rear touch panel 21. The groove 12g may also have a function of guiding a user to the rear touch panel area 21.
    [0048] As shown in FIG. 4, the guide 12f is offset downwards vertically with respect to the rear touch panel 21. That is, the center of the top-down direction of the guide 12f is positioned lower than the center C1 of the rear touch panel 21. A the lower end of the guide 12f is positioned lower than the lower edge of the rear touch panel 21. Consequently, the tip of the middle finger placed on the rear surface can be more easily placed on the guide 12f. The guide 12f, in this example, is formed having a substantially oval shape that is long from top to bottom. With the width from top to bottom of it substantially corresponding to that of the rear touch panel 21.
    [0049] As shown in FIG. 11, the rear surface of the electronic device 1 includes an inclination 12h formed between the deepest position PI of the guide 12f and the edge 12g of the guide 12f towards the rear touch panel 21. With this structure a finger resting on the guide 12f can easily move towards the rear touch panel 21. In this example, the surface of the guide 12f is curved in its cross section. Specifically, the cross section of the guide 12f has an open arc shape behind the electronic device 1. The slope 12h constitutes a part of the curved surface.
    [0050] As shown in FIG. 4, a space is ensured between the guide 12f and the left / direct edge of the area where the rear touch panel 21 is located. That is, the edge 12g of the guide 12f towards the rear touch panel 21 is positioned outside the left / right edge of the rear touch panel 21. This structure can prevent a finger from resting on the guide 12f when mistakenly touching the touch panel rear 21.
    [0051] In addition, the guide surface 12f is made of material different from the material that forms the surface of the rear touch panel area 21. In this example, as shown in FIG.ll, the guide 12f is integrally formed with the housing rear 12. The rear cover panel 13 has an opening formed in a position corresponding to the guide 12f and a part of the rear housing 12 is exposed in the opening. The exposed part constitutes the guide 12f. However, the flat surface 13b surrounding the guide 12f is formed by the rear cover panel 13.
    [0052] As shown in FIGS 3 and 4, the rear cover panel 13 is slightly smaller in size than the rear housing 12 in the rear view of the electronic device 1. Specifically, in this example, the width from top to bottom of the panel rear cover panel 13 is smaller than that of the rear cover 12, and consequently, the upper part 12c of the rear cover 12 is positioned higher than the top edge of the rear cover panel 13. As shown in FIG. 7 or 8, a step K is formed between the edge of the upper part 12c of the rear housing 12 and the upper edge of the rear cover panel 13. In other words, the surface of the rear cover panel 13 is positioned slightly behind the than the edge of the uppermost part 12c of the rear housing 12. With this structure, a user can recognize the area of the rear touch panel 21 by touching the step K when moving his finger from the uppermost part 12c towards the rear touch panel 21 .
    [0053] In this example, as shown in FIG. 4, the width from left to right of the rear cover panel 13 is smaller than that of the rear housing 12. Therefore, the outer circumferential portion of the rear housing 12 surrounds the rear cover panel 13.0 step K is formed between the circumferential portion outer of the rear housing 12 and the outer circumferential edge of the rear cover panel 13.
    [0054] As shown in FIGS. 1, 5 and 6, the leftmost part 12E and the rightmost part 12R of the rear surface of the electronic device 1 are curved. That is, the rear surface of the rear cover panel 13 has a curved surface towards the front surface of the electronic device 1. The curved surface of the leftmost part 12E is curved so as to be closer to the front surface of the electronic device 1 as you go to the left side. Similarly, the curved surface of the rightmost part 12R is curved in such a way that it is closer to the front surface of the electronic device 1 as it goes to the right side. With this structure, a user can more easily support the rear surface of the electronic device 1, compared to a structure in which each of the rightmost part 12R and the leftmost part 12L has an acute angle.
    [0055] As shown in FIG.7, the uppermost part 12c of the rear surface is also curved. That is, the rear surface includes a curved surface located at the uppermost part 12c and curved towards the front surface of the electronic device 1. The curved surface of the uppermost part 12c is curved such that it is closer to the front surface of the electronic device 1 as it goes up. With this structure, a user can gently move his finger from the upper surface 11c of the electronic device 1 towards the rear touch panel 21. In this example, the lower part 12d of the rear surface is also curved towards the front surface of the electronic device 1.
    [0056] As described above, the rear surface of the electronic device 1 includes, on the outer circumferential part of it, a curved surface that curves towards the front surface of the electronic device 1. In this example, the curved surface is formed over the entire circumference of the rear surface. The rear touch panel 21 and the guide 12f are positioned in the area surrounded by the outer circumferential part. The curved outer circumferential portion is formed by the rear housing 12. That is, the rear housing 12 is formed as a plate whose edge is curved towards the front surface of the electronic device 1.
    [0057] The outer edge of the outer circumferential part of the rear housing 12 (ie, the uppermost part 12c, the lowermost part 12d, the rightmost part 12R, the leftmost part 12L) continues to the upper surface 11c, lower surface 11b, right side surface 11R and left side surface 11L of the front housing 11. As shown in FIG.5, the height H1 of the curved surface formed on the outer circumferential part is slightly wider than the height H2 of the upper surface 11c or the like. In addition, the width W of the curved surface is slightly wider than the height H1 of the curved surface.
    [0058] As shown in FIG. 3 or 4, the camera 24 is provided on the rear side of the electronic device 1. Specifically, in this example, the camera 24 is positioned on the uppermost part 12c of the center, in the left to right direction of the electronic device 1. The surface The front of the camera 24 is positioned concave in relation to the rear surface of the electronic device 1 (the surface of the rear cover panel 13). Therefore, when the electronic device 1 is placed on the surface, the front surface of the camera 24 is positioned away from the surface (the surface where the electronic device 1 is placed), so that the front surface of the camera 24 can be preserved dirt.
    [0059] A plurality of operational members are provided on the surface forming the outer circumference of the electronic device 1 (specifically, the surface of the right side HR, the surface of the left side 11L, the upper surface 11c, and the lower surface 11b of the housing frontal 11, all hereinafter referred to as circumferential surface). These operational members on the circumferential surface are arranged to avoid the right side surface 1 IR and the left side surface HL. With this arrangement, a user can avoid erroneously moving the operating member when holding the IR, 1L parts. In this example, as shown in FIG. 6, the button 8a, 8b, 8c are provided on the upper surface 11c. Button 8a is, for example, a power button, and buttons 8b, 8c are, for example, volume buttons.
    [0060] As shown in FIG. 6, electronic device 1 includes covers 15a, 15b, forming a part of the upper surface 11c. A slot for inserting storage in a card-type recording medium, for example, a program for a game is formed within the cover 15a. The cover 15a covers the crack. However, a terminal, for example, a USB terminal, for connecting an accessory and a peripheral device of the electronic device 1 is formed within the cover 15b. Cover 15b covers the terminal.
    [0061] As shown in FIG.3 the electronic device 1 includes a cover 15c constituting a part of the curved surface 12L. A slot for inserting a storage medium in a card-type recording medium is formed within the cover 15c. The cover 15c covers the slot.
    [0062] Terminals 16a, 16b for connection to a terminal of an external device are provided on the circumferential surface of the electronic device 1. Specifically, the terminals provided on the circumferential surface are all arranged to avoid the surface of the right side 11R and the surface on the left 11L. More specifically, as shown in FIG. 5, the terminals 16a, 16b are provided on the lower surface 11b. Terminal 16a is a power terminal or USB terminal for connecting a charging device to charge the battery of electronic device 1. Terminal 16b can be, for example, a headphone terminal or a microphone. The cover 15d is provided on the curved surface of the lower part 12d, and a slot for inserting a storage in a card-type recording medium is formed within the cover 15d. The cover 15 covers the slot. The cover 15d is curved and forms a part of the curved surface of the lower part 12d.
    [0063] As shown in FIGS. 1 and 2, the button 14R is provided in the rightmost position of the upper surface 11c (in other words, the uppermost position of the right side surface 1 IR). The button 14U is provided in the leftmost position of the button (in other words, the position above the surface of the left side 11U). As shown in FIG. 9, a user can bend his index fingers over the respective buttons 14R, 14U, while holding the IR, 1L parts. The buttons 14R, 14U can move to be concave in relation to the upper surface 11c. That is, the 14R, 14U buttons can move downwards.
    [0064] As shown in FIG. 2, the upper surfaces (a surface pressed by a finger) of the buttons 14R, 14L are curved in accordance with the surface on the right side ÍÍR and the surface on the left side 11L. In other words, the upper surface of the button 14R is flush with the surface of the right side 11R. The edge of the button 14R and the edge of the right side of the front housing 11 together form a substantially semicircular shape as a whole in front view of the electronic device 1. Similarly, the upper surface of the button 14L is flush with the surface of the left side 11L, and the edge of the button 14L and the edge of the left side of the front housing 11 together form a substantially semicircular shape as a whole in front view of the electronic device 1. Therefore, as shown in FIG. 9, the user's index fingers, with their tips resting on the respective buttons 14R, 14L, are moderately folded. As a result, a user can easily extend his other finger (specifically, the middle finger) placed on the rear surface of the electronic device 1 towards the rear touch panel 21.
    [0065] As described above, according to electronic device 1, the rear touch panel 21 is provided in an area located higher than the position P opposite the operational rods 3R, 3L provided on the parts to be secured 1R, 1L, respectively. This arrangement allows a user to smoothly * operate the rear touch panel 21, while holding the 1R, 1L parts.
    [0066] In addition, the rear touch panel 21 is offset upwardly vertically in relation to the 3R, 3L operating rods. According to this layout, a user does not need to extend his finger placed on the back surface towards the bottom of the electronic device 1, and therefore, he can stably hold the electronic device 1.
    [0067] Each operational stick 3R, 3L is movable in the radial directions around the respective operational stick 3R, 3L. As input to a driving instruction, using the 3R, 3L operating poles, it is easy for a user to keep their fingers on the 3R, 3L operating poles most of the time. Therefore, the formation of the rear touch panel 21 in an area above the opposite positions of the respective 3R, 3L operating rods allows a user to smoothly operate the rear touch panel 21 for use in more numbers of scenes.
    [0068] The rear surface of the electronic device 1 has a guide 12f to guide a user in the area where the rear touch panel 21 is located. This structure can prevent erroneous touch on the rear touch panel 21 by a user's finger. Note that the guide 12f can be formed in a member that constitutes the rear surface of the electronic device 1 (for example, the housing or cover that constitutes the rear surface of the electronic device 1), or a different member of the member constituting the rear surface of electronic device 1 can be provided as a guide.
    [0069] A space is ensured between the guide 12f and the area where the rear touch panel 21 is provided. Space can prevent a user's finger from mistakenly touching the rear touch panel 21.
    [0070] The surface of the guide 12f has a different style than the surface of the area where the rear touch panel 21 is located. With this structure, erroneous touch on the rear touch panel 21 by a user's finger can be more safely avoided.
    [0071] In addition, the rear surface of the electronic device 1 is concave on the guide 12f. With this structure, a user can rest his / her finger on the concave portion when he / she does not intend to use the rear touch panel 21, in order to avoid erroneous touch on the rear touch panel 21.
    [0072] The rear surface of the electronic device 1 has a 12h slope between the deepest PI position of the guide 12f and the edge 12g of the guide 12f towards the rear touch panel 21. The 12h slope can prevent a user's finger from getting stuck on the edge 12g of the guide 12f. Consequently, a user can gently extend his finger towards the rear touch panel 21.
    [0073] The material constituting the surface of the guide 12f differs from that of the surface of the area where the rear touch panel 21 is located. With this structure, erroneous touch on the rear touch panel 21 by a user's finger can be more easily avoided.
    [0074] The width (the top to bottom width in the description above) of the rear touch panel 21 is less than that of the display area 2. This structure facilitates the layout of the components (for example, an antenna) that requires a sufficient distance from both the display area 2 and the rear touch panel 21, while ensuring sufficient size for the display area 2.
    [0075] The rear touch panel 21 is offset upwardly vertically from the center C2 in the top-down direction of the electronic device 1. This arrangement of the rear touch panel 21 facilitates the layout of the components arranged within the electronic device 1.
    [0076] The outer circumferential part of the rear surface of the electronic device 1 is curved towards the front. With this structure, a user can more easily place his finger on the back surface of the electronic device 1.
    [0077] The rear surface includes a flat surface that continues downward from the surface of the area where the rear touch panel 21 is located. With this structure, a user can more easily move his finger basically in a top-down direction on the rear touch panel 21 as the finger is not, for example, caught on the edge of the rear touch panel 21.
    [0078] The edge of each part to be held 1R, 1L is curved in a semi-arc shape in front view of the electronic device 1. With this part's shape to be held 1R, 1L, a user can more easily move his finger on the rear surface of the electronic device 1, while holding the parts 1R, 1L.
    [0079] Note that the present invention is not limited to the electronic device 1 described above, and several modifications are possible.
    [0080] For example, the present invention can be applied to a portable electronic device (a gaming device) that includes an upper housing and a lower housing to be opened and closed. In this case, an operational member can be provided on the lower housing, and a rear touch panel can be provided on the rear surface of the upper housing.
    [0081] In addition, the left and right edges of the electronic device 1 may not be curved as such. That is, the electronic device 1 can be substantially formed from a solid rectangle.
    [0082] In addition, although the operational rods 3R, 3L are provided to the right and left of the display area 2, respectively, in the electronic device 1, the operational rod can be provided only to one of the right and left areas of the area display 2.
    [0083] Furthermore, the rear cover panel 13 is provided on the outermost surface of the rear touch panel 21, and the surface of the rear touch panel area 21 is flush with the area surrounding the rear touch panel 21. However, a step can be formed between the area of the rear touch panel 21 and the surrounding area.
    [0084] In addition, although the rear touch panel 21 is offset upwardly vertically with respect to the display area 2 in the description above, the rear touch panel 21 can be provided in a position directly opposite the display area 2. In addition In addition, although the rear touch panel 21 is offset upwardly vertically relative to the electronic device 1, the center C1 in the top-down direction of the rear touch panel 21 can coincide with the center C2 in the top-down direction of the device electronic 1.
