Claims

[Scope of utility model registration request]

(1) A disk comprising a cassette formed by combining an upper shell and a lower shell made of synthetic resin, in which a head insertion window and a drive shaft insertion hole are formed, and a disk rotatably housed within the cassette. The cassette has circular openings provided in corresponding positions in the upper shell and the lower shell, respectively, other than the area where the disk is disposed, and teeth on the circumferential surface thereof, and the cassette is rotatable within the opening. a counter disposed on the counter, an elastic counter stopper with a wedge-shaped protrusion that comes into contact with the circumferential surface of the counter, and a counter stopper that fixes the counter stopper and locks the rotation of the counter when not in use. A disc cassette, further comprising a release plate slidably disposed within the cassette so as to release the fixation of the counter stopper during use.

(2) The counter stopper has holes at both ends into which pins installed in the cassette are inserted, and a wedge-shaped projection at the center. Disc cassette as described in section.
