The adapter device comprises a ring (2) of flexible material, in particular card, having an outer perimeter (3) which at least partly corresponds to the outer circumference of a standard optical disc, and an inner perimeter (4) which at least partly corresponds to the outer circumference (5) of a compact disc (1) of a size smaller than the standard size. The adapter ring (2) is folded along predetermined fold lines (L1, L2) in such a way that when in the folded condition it can have dimensions which are close to or smaller than the external diameter of the compact disc (1).

A disk cartridge does not require a plate supporter for holding a chucking plate on an upper shell. In this disk cartridge, a chucking plate (5) for chucking a disk (4) on a turntable (41) driven by a spindle motor is not supported by an upper shell (2) but placed on the middle of the disk (4) so as to be vertically movable together with the disk (4), and a peripheral cylindrical rib (6) being not in contact with the disk (4) and functioning as positioning means for limiting movement of the chucking plate (5) in the direction of its diameter while permitting the vertical movement of the chucking plate (5) is molded integral with the lower surface of the upper shell (2).
摘要:
A cartridge receiving casing (20) capable of permitting a cartridge (60, Fig. 6) to be readily removed from the casing by one hand as required while preventing the cartridge from accidentally falling from the casing. The casing includes a casing body (30) formed so as to be open on one side thereof to provide the casing with an opening (20a) through which a cartridge (60) is inserted into and taken out of the casing and a cover (40) slidably arranged on the casing body (30). The cartridge is engaged with first projections (52a) of stoppers (50A, 50B) at a received position, to thereby be elastically supported in the casing. When the cover (40) is slid to an intermediate position toward the opening (20a), the cartridge is partially exposed through the opening (20a) and elastically supported while being drawable out of the casing. Further sliding of the cover (40) permits the cartridge to be removed from the casing.
