Claims

[Scope of utility model registration request]

In order to load the rotating recording medium into the playback device, a case consisting of a jacket containing the rotating recording medium and a lid detachably connected to the jacket and closing the front opening of the jacket is inserted deep into the playback device. In the mechanism for partially pushing the jacket back out of the playback device when the case is inserted, a jacket push-back member that is pushed when the case is inserted and moves against a spring and pushes back a part of the jacket after the case insertion operation is released; It is arranged near the upper center of the insertion path in the left and right direction,
The jacket push-back member applies a push-back force to a substantially central position in the left-right direction of an expansion mechanism that moves while being guided by left and right guide rails to expand the front opening of the jacket when the case is inserted. A rotating recording medium storage jacket push-back mechanism of a rotating recording medium playback device.
