It can be used for both purposes and its effect is great. Next, a case where the cartridge 1 is detached from the apparatus will be described. Based on the attachment / detachment command, the motor 38 rotates in the direction opposite to that at the time of loading, and the slide cams 28, 28 move in the direction opposite to the arrow 1c. As a result, the attaching / detaching operation is the reverse of the loading operation, and the cartridge 1 eventually comes to the position shown in FIG. 3b, that is, the standby position of the motor 38 at the loading time. Further, the motor 38 rotates and the slide cams 28, 28 move from the standby position to the front panel 2a side. Therefore, the abutment cam portion 33 of the slide cams 28, 28 is connected to the cam follower shaft 18 of the cartridge holding plate 15.
, The cartridge holding plate 15 rotates in the direction opposite to the arrow 15b, and the holding shaft 17 separates from the recess 1a of the cartridge 1. As a result, the cartridge contact lever 13 moves in the direction opposite to the arrow 1c due to the pressing force of the coil spring 15a, and the cartridge 1 that has been in contact with the cartridge contact lever 13 passes through the rotary lid 2b of the front panel 2a and is discharged to the outside of the apparatus. To be done. Thereafter, the motor 38 rotates in the reverse direction, that is, at the time of loading, and returns the slide cams 28, 28 'to the standby position.
