<p>PURPOSE:To prevent the mixing of dust and to miniaturize a device by providing first and second releasing means to release first and second interrupting means to interrupt the moving of a cartridge and a drawer into a frame and controlling them with the opening and closing operation of a door. CONSTITUTION:A cartridge is inserted from an inserting port and mounted to a drawer 4 which can move freely the top of a frame 2. When a door 3 is turned, an opening closing means opens the access door of a cartridge, further, when the door 3 is turned, the first releasing means 21 releases first interrupting means 24 and 26 and releases the inserting and interrupting of the cartridge into the frame 2. Further, when the door 3 is turned and completely closed, the second releasing means of the door 3 releases second interrupting means 19 and releases the moving interrupting of the drawer 4. The drawer 4 moves on the frame 2, is locked to a prescribed position by a locking means 32 and a detecting means 29 detects this. Thus, the mixing of an external dust is prevented and the device can be miniaturized.</p> |
