Claims

[Scope of utility model registration request]

In an apparatus in which a storage drum that accommodates cartridges in a radial arrangement is rotated by a motor and locked and stopped at a designated position, and a deck is loaded with a designated cartridge and played, the cartridge is removed from the deck. After the storage drum is ejected, the lock pin is removed from the locking hole of the storage drum to unlock the storage drum, and the storage drum is rotated once in a direction opposite to the forward direction in which it is intended to rotate. and a motor circuit for controlling the rotation of the motor so that the motor rotates in the forward direction.
