<p>PURPOSE:To prevent a cassette from being pushed up with force to close a lid and to hold the cassette in a prescribed position without fail by abutting the both edges of a turning member, which is supported with being freely turnable, to a holder to hold the lid and cassette. CONSTITUTION:When a cassette 1 is inserted up to the position to be abutted to a holder 5, a lid 2 is held in a position close to a sliding surface 10 of a turning member 13. Next, when the holder 5 is caused to fall to a chassis 4, the lid 2 and the sliding surface 10 are abutted. When the holder is caused to fall further, the lid 2 is slided along the shape of the sliding surface and opened. Continuously, at a time point a positioning guide 6 goes into the recessing part of the cassette 1, the holder 5 pushed a projecting part 11 and the turning member 13 is turned in a clock-wise direction with a pin 4 as a shaft. Then, the sliding surface 10 presses the lid 2 and opens it. Thus, a height guide 7 is abutted to the lower surface of the cassette 1 and the positioning guide 6 is engaged with a recessing part 3. Then, the cassette can be held in the prescribed position.</p> |
