Abstract
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 Analysis
Total Claims: 18
Claim 1
Independent Claim
93 words
An element for receiving and retaining a rigid circular information disc, comprising an injection molded plastic tray adapted to be inserted into a storage cassette, which tray has a disc receiving recess and retaining means for retaining the information disc in the recess, characterized in that the tray, which is constructed as an easy-to-remove and easy-to-introduce insert for the storage cassette, is adapted for use as a drawer-type insert for a player, the retaining means including resilient retaining means and fixed retaining means arranged opposite each other at the edge of the recess.
Claim 2
Dependent Claim
93 words
An element for receiving and retaining a rigid circular information disc, comprising an injection molded plastic tray adapted to be inserted into a storage cassette, which tray has a disc receiving recess and retaining means for retaining the information disc in the recess, characterized in that the tray, which is constructed as an easy-to-remove and easy-to-introduce insert for the storage cassette, is adapted for use as a drawer-type insert for a player, the retaining means including resilient retaining means and fixed retaining means arranged opposite each other at the edge of the recess.
Claim 3
Dependent Claim
29 words
An element as claimed in claim 1, characterized in that one side of the tray carries a grip member, the resilient retaining means being arranged near the grip member.
Claim 4
Dependent Claim
26 words
An element as claimed in claim 2, characterized in that the tray is formed with a first aperture at the location of the resilient retaining means.
Claim 5
Dependent Claim
38 words
An element as claimed in claim 3, characterized in that at the side of the recess the first aperture has an arcuate bounding wall which is substantially concentric with the centre of an information disc to be inserted.
Claim 6
Dependent Claim
28 words
An element as claimed in claim 4, characterized in that the arcuate bounding wall has a portion which recedes towards the centre and faces the resilient retaining means.
Claim 7
Dependent Claim
56 words
An element as claimed in any one of the claims 3 to 5, characterized in that the resilient retaining means comprises a projection arranged in the centre of a resilient member whose ends are secured to the grip member and in that the first aperture extends over the entire width and depth of the resilient member.
Claim 8
Dependent Claim
25 words
An element as claimed in claim 6, characterized in that the resilient member is constructed as a metal spring onto which the projection is molded.
Claim 9
Dependent Claim
19 words
An element as claimed in claim 6, characterized in that spring means supports the resilient member in its centre.
Claim 10
Dependent Claim
44 words
An element as claimed in claim 8, characterized in that the spring means comprise a spring rod, which is clamped in at its ends, which is arranged behind the resilient member and which bears against the resilient member at the location of its projection.
Claim 11
Dependent Claim
25 words
An element as claimed in claim 8, characterized in that the spring means are constructed as resilient projections which are connected to the grip member.
Claim 12
Dependent Claim
63 words
An element as claimed in claim 4, characterized in that the resilient retaining means comprises a projection arranged in the center of a resilient member whose ends are secured to the grip member and in that the first aperture extends over the entire width and depth of the resilient member, and the resilient member bears against the bounding wall of the first aperture.
Claim 13
Dependent Claim
40 words
An element as claimed in claim 11, characterized in that a second aperture is formed in the bottom of the recess and has a bell-shaped widened portion at the location of the fixed retaining means, said second aperture being U-shaped.
Claim 14
Dependent Claim
46 words
An element as claimed in claim 12, characterized in that the tray comprises guide strips which extend perpendicularly to the grip member, which guide strips provide a correct guidance during insertion of the guide, thereby ensuring a correct cooperation with a loading/unloading mechanism of the player.
Claim 15
Dependent Claim
20 words
An element as claimed in claim 13, characterized in that the injection-moulded plastics tray is formed with loading/unloading guide means.
Claim 16
Dependent Claim
22 words
An element as claimed in claim 1, characterized in that the tray is made of heat resistant plastic, containing mainly a polycarbonate.
Claim 17
Dependent Claim
40 words
An element as claimed in claim 3, characterized in that a second aperture is formed in the bottom of the recess and has a bell-shaped widened portion at the location of the fixed retaining means, said second aperture being U-shaped.
