Claims

[Scope of utility model registration request]

A storage drum that stores cartridges in a radial arrangement is rotated by a motor, locked and stopped at a designated position, and a deck is rotated by the motor in a device in which a designated cartridge is mounted and played. 1st
A spring member is provided between the rotary body and a second rotary body that rotates the storage drum by the rotation of the rotary body, and the spring member normally rotates the second rotary body by rotating the storage drum. A cartridge storage drum drive mechanism of an automatic cartridge selection and performance device, which is configured to rotate integrally with the first rotary body and deform after the storage drum is locked to allow extra rotation of the first rotating body.
