Claims

[Scope of utility model registration request]

A storage drum that stores cartridges in a radial arrangement is rotated by a motor and stops at a designated position 4.
In a device that is played with a cartridge with a specified deck installed, there is a locking mechanism that locks the storage drum at the specified position using a lock pin or the like, and a A cartridge storage drum locking mechanism for an automatic cartridge selection performance device, comprising a motor circuit that decelerates the rotational speed of the storage drum in stages.
