ABSTRACT:
A disc cassette includes a rotatable disc (1) 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) to retain 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. A slot (15) formed in the main wall (3) of the enclosure (2) 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).
