<p>PURPOSE:To perform the unlock operation of a lock member without necessitating an electromagnet, etc., by operating a presser linking with the opening/ closing operation of a cartridge carrier mechanism in an auto loading mechanism, and releasing the lock of a cartridge. CONSTITUTION:Carrier rollers 8a, 8b are closed by an opening/closing mechanism 11 in a state where a designated cartridge arrives at a loading position, which sandwiches the cartridge 6a from right and left sides. At this time, since the holders 18a, 18b of the carrier rollers 8a, 8b are also moved in a closing direction, the presser 13 located at the tip of an operating lever 12 mounted at the holder 18a is also moved to a cartridge 6a side, which presses the pressing part 10b of the lock member. As a result, a lock lug 10a located at the inner terminal of the lock member is retreated, and comes off the notch 9 of the cartridge 6, which enables the cartridge 6a to be loaded. In such a way, it is possible to perform the releasing operation of the lock of the cartridge by unlocking the cartridge 6a by using the opening/closing power of the holder 18a of a carrier means without providing the electromagnet, etc., in a driving source.</p> |
