PURPOSE: To save a constitutional space by providing a slide member to slide on a loading ring, transmitting a drive force of a driving means to the slide member and actuating a cassette holder locking means by the slide member.
CONSTITUTION: On completion of unloading, the loading ring 2 is stopped at a specific position. At that time intermesh takes place between one end part of the slide member 3 fitted slidably on the ring 2 with pin 12 and a transfer gear 8 for transmitting a torque of a reducing gear 7 for reducing the torque of a loading motor 6, and a calked pin 13 is brought into contact with a rod 9. When the ejection mode becomes operative, the motor 6 rotates further and its torque is transmitted through the reducing gear 7 and transfer gear 8 to the gear part of the slide member 3 which is then slid in the rotational direction 14 to operate a cassette holder locking device. In such a way as composing the slide member 3 onto the loading ring 2, the ejection operation is thus feasible by utilizing the torque of the loading motor 6.
