Claims

[Scope of utility model registration request]

A jacket body having an opening at the front end and storing a rotating recording medium therein, and a plate-shaped jacket which is removably connected to the jacket body using locking claws arranged on the left and right sides and which closes the front end opening. By inserting and removing a jacket consisting of a jacket lid, the jacket lid comes off from the jacket body and is held inside, and the rotating recording medium comes out of the jacket body and is placed on the turntable. In a rotary recording medium reproducing apparatus that reproduces a recording medium by using a rotary recording medium, the locking pawl has a groove extending in the jacket insertion direction on the outer surface thereof, and is provided at the inner part of the reproducing apparatus, and the retaining pawl is provided in the inner part of the reproducing apparatus, and is A coupling release member that acts on the left and right locking claws to displace the locking claws inward to release the coupling with the jacket body is fixed by locking the outer surface of the locking claws. A first arm portion that displaces the pawl inwardly and engages with the groove, and opposes the inner surface of the locking pawl that has been displaced inwardly to restrict further inward displacement of the locking pawl. The jacket lid is held in a state in which the locking claw is positioned between the first and second arm parts of the coupling release member. A jacket lid holding mechanism for a recording medium playback device.
