Abstract

Tray (1) for receiving and retaining a rigid circular information disc (4). Can be inserted into a storage cassette (28) and comprises a recess (3) and retaining means (7, 15, 16) for retaining the information disc (4) in the recess (3). The tray (1), which constitutes an easy-to-remove and easy-to-introduce insert for the storage cassette, is constructed as a drawer-type insert for a playing apparatus. The retaining means (7, 15, 16), which include one resilient retaining means (7), are arranged opposite one another on the edge of the recess (3).

Claims

1. A combination of a storage cassette comprising a bottom and a pivotably connected lid with a removable tray, adapted to be inserted into said bottom, which tray has a disc receiving recess, retaining means for retaining an information disc in the recess and a grip member at one end characterized in that the lid is provided with at least one push-up projection which pushes the tray up from the bottom at the location of the grip member after a pivotal movement of the lid through more than 180°

.

2. A combination as in claim 1, wherein the lid is provided with two push-up projections, said grip member having respective abutment portions on opposite ends thereof, said push-up projections bearing against respective abutment portions after a pivotal movement of the lid through 180°

.

3. A combination as in claim 1 wherein said grip member has latching projections on opposite ends thereof, said storage cassette having respective hinge openings therein, said latching projections engaging said hinge openings to provide a pivotal connection of the lid to the bottom.

4. A combination as in claim 3 wherein said latching projections are resilient.

5. A combination as in claim 4 wherein the tray comprises a pair of guide strips extending perpendicularly of the grip member on opposite sides of the tray, the bottom of the cassette having a pair of respective opposed sidewalls which receive said tray between the inner surfaces thereof, said inner surfaces having projections which engage respective guide strips to latch the tray remote from the grip member.

6. A tray for receiving and retaining an information disc, having a disc receiving recess and retaining means for retaining the disc in the recess and having a grip member at one side, characterized in that the tray has a lower surface formed with at least one elongate recess arranged near said grip member on an opposed upper surface formed with at least one upstanding lateral edge portion opposite said disc receiving recess from the grip member, the upper and lower surfaces of each tray being profiled so that the trays can be stacked after they have been turned through 180°

relative to each other, in such a way that after stacking the lateral portion of a first tray engages the elongate recess in a second tray.

7. A tray as claimed in claim 6, characterized in that the grip member has a first bevelled edge at the side of the grip member facing the said one side of the tray, the side of the tray facing the grip member being formed with a second bevelled edge, the first bevelled edge of the first tray adjoins the second bevelled edge of the second tray after the trays have been stacked.
