PURPOSE:To avoid the damage or a fault of a cassette by securing the interlock between a shutter open/close mechanism and a cassette loading/unloading mechanism, loading the cassette after a shutter is opened and then unloading the cassette after the cassette is floated up. CONSTITUTION:A cassette control part 81 consisting of a shutter lever 82, a lock lever 90, a stop lever 96, etc. is disposed on the upper surface side of a cassette holder 70. A push part 83 of the lever 82 is disposed cooperatively with a shutter 240 of a cassette 230. When the cassette 230 is loaded, the lever 82 of the part 81 is turned counterclockwise. Then the cassette 230 is loaded after the shutter 240 is opened. Therefore a head is never moved down while the shutter is closed and the damage of the head is prevented. The the cassette 230 is ejected after it is floated up. The damage or the fault of the cassette can be prevented owing to a stable operation. |
