The forward movement of the elevator holder 20 is blocked by the inclined portion 48a of the elongated hole 48, so that the elevator holder 20 It is locked and cannot move forward.

[0045] Then, the cassette C is inserted into the elevator holder 20. Then, at first With the beta holder 20 locked, only the cassette C moves forward, and this relative movement Then slider 1 is opened as described above. In the middle of opening slider 1, the cassette The tip of the lever C reaches the downward protrusion 44a of the lock release lever 44, and the lock release lever -44 moves forward. Then, the left inclined contact surface 44b pushes the switch lever 50. Rotate to turn on the switch 54 and push the upward pin 45 of the lock lever 42 passes through the right side parallel contact surface 44c and enters the right side inclined contact surface 44d, and the elevator hoist Unlock the folder 20. There, the motor is started and the elevator holder 2 0 moves forward together with cassette C, then the lid 2 opens and descends to load the loader. reaching the starting position. During this forward movement, the cassette ejection levers 56 and 58 are ejected. The output rollers 62 and 66 are waiting at positions where they do not come into contact with the cassette C.

[0046] When ejecting cassette C, the eject signal causes the motor to move in the opposite direction from when it was inserted. to start. Then, the elevator holder 20 rises together with the cassette C, and the lock lever The upward pin 45 of the bar 42 is connected to the right locking surface 44e of the lock release lever 44 and It engages with the side surface on the tip side of the ejection assisting lever 52, and the elevator holder 20 is ejected. move in the direction. The ejection auxiliary lever 52 is interlocked with the elevator holder 20 to remove the cassette. The discharge levers 56 and 58 are operated greatly in the discharge direction. On the way, the cassette The ejection rollers 62 and 66 of the ejection levers 56 and 58 catch up with the cassette C, and the cassette Push C out a lot. The elevator holder 20 returns to the initial position with a delay, and finally All parts return to their initial positions.

[0047] In this way, upon insertion, the lock release lever 44 turns on the switch 54 and Move the cassette C to the elevator holder 2 by a predetermined stroke to release the lock. 0, and if there is no autochanger device, the motor The machine had to be pushed in by hand until it activated. Autochanger device with the above configuration In this case, the cassette ejecting pin 90b provided on the first link 90d of the slider 90 is This causes the cassette C to be pushed forward significantly. The release lever 44 can be moved forward by the stroke necessary to operate it.

[0048] Furthermore, during ejection, the cassette C is pushed by the ejection rollers 62 and 66, and the cassette The rear end surface of C (the leading end surface in the ejection direction) extends to the outside of the rear end of the elevator holder 20. It protrudes greatly, thereby causing the When you reach the slider 90, which is waiting at a position slightly retracted from the position on the tip side, I can reach it. Therefore, the cassette locking pin 90c is inserted into the positioning hole on the bottom surface of the cassette C. 9a, and the magazine 76 is stored in a cassette by the backward movement of the slider 90. It is reliably stored in the portion 76a.
