    The invention relates to a pointer device for specifying x-y coordinates. The pointing device has a unit slidable in the x-direction in which a guide belt (9) rotatable in the y-direction can roll circumferential rollers (Sa-b). The guide belt extends around at least three rollers arranged parallel to each other (Sa-b), which means that the guide belt has support over large parts of its surface but can still roll easily over the rollers. In one embodiment, the rollers (Sa-b) are mechanically coupled to each other, so that they all roll synchronously with each other, which makes the guide belt roll particularly easily. The rollers can be provided at least at the sine end with drive struts (6), where the drive struts are connected to each other with end drive belt. Alternatively, the rollers at at least one end may be provided with drive gears (11), each pair of adjacent drive gears (1 1) engaging an intermediate intermediate gear (12) so that the rollers roll synchronously with each other. 10/13

Fig. 10 shows the second embodiment of the rollers mounted in the bottom part. Fig. 11 shows a third embodiment of the rollers with roller rods. Fig. 12 shows a second embodiment of the bottom part with sliding rods. Fig. 13 shows in partial section in greater detail the short side of the second embodiment of the bottom part Description of preferred embodiments Fig. 1 shows a bottom part 1 and associated grooves 2a, b for a pointer device according to the invention.
    The bottom part 1 consists of a rectangular box with an open top. On each of the short sides of the bottom part, there are five semicircular recesses 3a on the upper edge of the coit side. The recesses are evenly distributed over each short side and each recess on one short side is placed at the same distance from the long sides as a corresponding recess on the other short side.
    In each corner of the bottom part there is a sliding foot 4a which fits in a sunken groove in the grooves 2a, b. The two sliding feet along one long side of the bottom part fit in one groove and the two sliding feet along the other long side of the bottom part fit in the other groove. The grooves consist of elongate elements with an elongated, longitudinal recess that fits the sliding tips and allows the bottom part to slide back and forth along the grooves.
    Fig. 2 shows the bottom part 1 mounted in the grooves 2a, b. The grooves are longer than the long side of the bottom part, so that the pointer device can slide back and forth in the grooves.
    Fig. 3 shows a first embodiment of rollers which fit in the bottom part. The rollers have a circular cross-section and at both ends two cross-sectional elements protrude. The innermost, closest to the middle portions of the rollers, is a drive rod 6 has a larger diameter than the outermost and is intended to receive a drive belt. The outermost, which extends furthest from the central portions of the rollers, is a support rod 7 which carries the rollers when they are mounted in the bottom part.
    Fig. 4 shows the first embodiment of the five rollers 5a mounted in the bottom part 1. Each semicircular recess 3a in the bottom receives a support rod 7 on a roller, so that each roller extends from a recess to the corresponding recess on the opposite short side. All five rollers are thus arranged in parallel and evenly distributed over the bottom surface of the bottom part.
    Fig. 5 shows the bottom part and the first embodiment of the rollers with drive belt 8 mounted over the drive struts. The drive belt is closed and bends around the drive struts of the outermost rollers and runs above and below the intermediate rollers. The drive belt grips all the drive struts so that all the rollers run synchronously with each other.
    Fig. 6 shows the bottom part and the first embodiment of the rollers with the drive belt 8 and a guide belt 9. The guide belt runs over all the central portions of the five rollers and extends over the full length of the central portions. If a user pushes the guide belt in either direction, it rolls around all five rollers that surround it. All five rollers provide support from below for the drive belt so that it remains close to completely flat, but the rollers allow sliding storage in the recess of the bottom part to roll easily.
    Fig. 7 shows the pointer device with a lid 10 attached along the edge of the bottom part. The lid is shaped as a frame which reaches the upper edge of the bottom part around its entire circumference and covers the main part to the roller end portions and the outer sides of the two outermost rollers. The lid has semicircular recesses along its two short sides that match the recesses of the bottom part, so that the matching semicircular recesses form circular openings. The rollers support struts 7 are received in these openings so that with the lid joined to the bottom part all the rollers are kept in position and cannot fall out.
    Fig. 8 shows in greater detail a cross section through the end of a roller Sa with lid 10 and the bottom part 8.
    The support strut 7 fits in the recesses in the lid and bottom, while the drive strut 6 reaches the inside of the lid and the bottom part, so that the roller cannot be displaced in its longitudinal extent. The drive belt 8 fits exactly in the space between the drive rod and the lid and bottom, respectively. The drive belt is therefore prevented from leaving the drive rod but does not normally touch the lid or the bottom, so that the rollers can rotate with low rotational friction.
    Fig. 9 shows a second embodiment of the rollers 5b which in the same manner as in the first comprises middle portions and support struts 7. Between the ends of the middle portions of the rollers and the support struts 7 in this embodiment there are instead drive gears 11 which are used to drive all the rollers synchronously with each other. .
    Fig. 10 shows the second embodiment of the rollers mounted in the bottom part and here illustrated four intermediate gears 12 arranged between each pair of adjacent gear gears and engaging therein. With these intermediate intermediate gears, all the rollers are made to roll in the same direction and synchronously with each other, so that the guide belt easily rotates around the central portions of the five rollers.
    The first two illustrated embodiments of pointer devices according to the invention thus allow a user to move the pointer devices laterally along the grooves and can make the guide belt roll up and down. These two degrees of freedom can be used, for example, to control a cursor on a computer screen. In addition to the illustrated mechanical parts, sensors which detect the movements are of course required and this can be done, for example, with a standard camera device or the like.
    This sensor technology can be considered as well known in the field and is not described in more detail here.
    Fig. 11 shows a third embodiment of the rollers 5c with roller rods 14. The rollers 5c are substantially identical to those according to the second embodiment, but lack support struts 7. Through the center of the rollers extends in their longitudinal extent a cylindrical receiving hole 15 which receives cylindrical roller rods 14, which replace the struts. The rollers can rotate around the roller rods 14, which allows the roller rods to be axed relative to the bottom part and the lid, but of course they can still be arranged so that they can also rotate relative to the bottom part and the lid, which further reduces friction.
    Fig. 12 shows a second embodiment of the bottom part 1 with sliding rods 16a, b. The bottom part lacks the sliding feet 4a of the first embodiment and instead has four gripping parts 4b arranged in each of the four corners of the bottom part. The gripping parts project from the lower edge of the longitudinal sides of the bottom part and are provided with through holes, through which the sliding rods 16a, b can be pushed in.
    The bottom part can thus slide along the sliding rods, but can not leave the sliding rods in the way that the bottom part according to the first embodiment could potentially be pulled up from the grooves 2a, b. This reduces the complexity of the construction and allows the entire pointer device to slide or return to its upper position by spring action.
    If the pointer device is pressed down, a switch 17b is activated and a click function corresponding to that of a computer mouse is generated. When the pointer device either end position in the extension direction of the sliding rods, either of two end position switches 17a is activated instead, c. When the pointer device reaches an end position, the cursor can be arranged to continue to be displaced in the direction of the pointer device, even though it is further mechanically prevented. this direction. In this way, the pointer device can be made to operate over a larger screen area than would otherwise be possible.
    Fig. 13 shows in partial section in greater detail the short side of the second embodiment of the bottom part and the lid 10. The short ends of the five roller rods project through the short side of the pointer device through four circular openings and an elongated opening 3b which allows the highest roller to move towards or from the other rollers. In this way, the guide belt 9 can be tensioned or its tension can be made to lighten.
    The roller bar of the highest roller is held stretched towards the right side of the pointing device by two springs l8a, b. One extends obliquely upwards to the right and the other extends obliquely downwards to the right, so that their combined action is directed only to the right. The guide belt can have component to component variations and in addition its length can change slowly over time or with temperature variations. The springs l8a, b mean that the guide belt always has close to the same voltage.
