专利摘要:
A disc cassette intended for use in a system by means of which information can be stored on and/or read from a disc comprises a rotatable disc (1) which is contained in a disc-receiving space of an external enclosure (2), a front opening of the enclosure being closed by a closing member (7) which is latched in the enclosure by means of one or more resilient latching fingers (8) and thereby retains the disc. The latching finger (8) pivots in a direction perpendicular to the plane of the disc (1) and cooperates with the side wall of a latching recess (12) formed in the inner side wall of the enclosure. In accordance with the invention a slot (15) is formed in the main wall (3) of the enclosure (2), which slot extends from the front opening of the enclosure into the latching recess but has a width which is smaller than the width at the latching recess and smaller than the width of the latching finger, and the end portion of the slot (15) which terminates in the front opening of the enclosure is covered by the portion (7A) of the closing member which projects from the enclosure. This enables the latching finger to be pivoted towards the released position by external means and it also enables gripping means of a playing apparatus to engage, via the slot, behind the portion (7A) of the closing member (7) which projects from the enclosure in order to withdraw the released closing member from the enclosure (2).

The invention relates to instrument engineering and can be used in systems for recording and reading information.
The purpose of the invention is to increase reliability by simplifying the design. Fig. 1 shows the filled disc cassette, general view; in fig. 2 - the same plan view; in fig. 3 - block of the closing element,: plan view; in fig. A - section A – L; FIG. 3; in fig. 5 - internal one hundred: the rion of the semi-housing of the disk cartridge; in fig. 6 is a section BB in FIG. 5 (on an enlarged scale).
: The disk cassette contains a rotating disk 1 and an outer case 2, I having two main walls FOR and ЗВ (only one main wall is shown - 1 FOR). The cassette case contains three side walls - the rear wall 4,; the left side wall 5 and the right side I; Forged wall 6. Opposite the rear wall: 4, a front window is provided; which is closed by element 7 and communicates with the disc space 1. The closing element 7 comprises a front section 7A, located outside, and a section 7B, which is arranged inside the cassette case. Section 7A runs across the entire width of the cassette case and has a thickness equal to I thickness of the cassette case. Section 7B: is mounted in the space of the disk in the cassette case with some gap and closes the front
cassette case window.
i For locking or blocking the i of the covering element 7 in the housing

sets provided locking device
The device consists of two elastic snap-on fingers 8A and 8B, which are located in the same plane as the section 7B of the closing element (Fig. 4). The closing element is made of plastic by molding under pressure, and the snap fingers FOR and 8B are designed as integral parts of the closing element. From the remaining sections of the closing element they are separated by recesses 9A and 9B, for. except for their fixed ends 10A and 10B. At the free ends of the snap fingers, the supporting portions 11A and 11B are contained, respectively. The locking fingers 7 are displaced slightly upward from the plane of the section 7B so that when subjected to pressure or pressure they can pivotally rotate in the direction perpendicular to

This nominal plane is due to the elasticity of the plastic material.
The cassette case 2 consists of two semi-bodies 2A and 2B, on the inner sides of each and;) of which there are snap-fit recesses 12 (Fig. 5, 6) corresponding to the snap-fit fingers 8A and 8B. The peripheral walls 13 of the recesses 12 interact with the supporting portions 11A and 11B of the snapping fingers. Each latching notch has a lower portion 14 which restricts the hinge movements of the snap fingers.
Slots 15 are provided in the main walls ZA and ZV with snap-in grooves 14, which extend from the front window of the cassette case into the snap-in slot 14. The width of the slot 15 is smaller than the width of the snap-in slot 14 and less than the width of the support sections 11A and 11B of the snap fingers 8A and 8B, respectively. The front portion 7A of the closing member, which protrudes from the cassette case, covers the end portion of the slot 15 adjacent to the front window of the cassette case. Each latching pin may pivotally rotate to the unlocked or free position through the cooperating slot 15 by means of an external device (not shown). Each of the latching fingers has a protrusion 1bA and 16B, respectively, which comes into contact with the slot 15. The capture device of the player can come into contact with the front portion 7A along its periphery at the location of the slot 15, (Fig. 4). After the snap-fit fingers are pivotally rotated to the unlocked positions, the closure member may be pushed out of the cassette case by an external gripping device. The closing element 7 is connected to a ribbon-like engaging element 17, which bends the disk 1 with a gap so that when the closing element 7 is removed from the cassette case, the disk is also removed from the case.
The semi-hull 2A shown in FIG. 5 is identical to the semi-hull 2B. The locking grooves 12 and the slits 15 are located symmetrically with respect to the center of the disk 1, as well as the latched fingers 8A and 8B, i.e. Only one type of part is required to manufacture the cassette body.

Claim
1. A disk cassette for use in a recording-playback system comprising an external cassette body having parallel main walls, side walls and a front window providing access to an information disk disposed in the body, a covering element mounted to the side of the front window and partially located inside and partially outside the cassette case, a latch device for locking the lockable element, containing
ten
