<p>PURPOSE:To prevent the release of a cartridge holding state by a vibration, etc., by providing a locking means on the discharge surface of a cartridge mounted on a cartridge holder. CONSTITUTION:The cartridge 153 is eventually pressed to a front surface 1531 which is the insertion surface of the cartridge 153 if the cartridge is successively inserted to the cartridge holder. An eject arm 145 turns first in a clockwise direction and in succession the front end 892 of a cartridge finger 89 is also pressed to the front surface 1531 and arms 80, 81 connected by a link turn clockwise. The arm 80 slightly lifts a pin 69 by the clockwise turning thereof when the cartridge 153 is inserted down to the position where the cartridge is approximately completely mounted in the holder. An engaging pawl 9 formed at the front end and a pin 69 are thereby locked.</p> |
