<p>PROBLEM TO BE SOLVED: To prevent the inclination of a tray when the tray passes the corner part of guide grooves. SOLUTION: The cassette loading mechanism has the tray 3 for holding a cassette 6 freely movably in cassette insertion and discharge directions on the inner side of the side plates 2 and 2 on a chassis 1. Two protrusion shafts 30 and 31 protrude from the tray 3 and the side plate 2 is provided with the guide grooves 20 and 21 in which the protrusion shafts 30 and 31 are respectively fitted. The respective guide grooves 20 and 21 are constituted by connecting an insertion guide groove 22 extending in a tray movement direction and a downhill sloping groove 23 extending in a chassis mounting direction from the top end of the insertion guide groove 22. The top end of the side plate 2 is provided with a stopper piece 4 in contact with the top end of the tray 3 in the position where the protrusion shafts 30 and 31 arrive at the intersection part of the insertion guide groove 22 and the downhill sloping groove 23. The inclination of the try 3 by the drop of the protrusion shaft 31 existing on the cassette discharge side into the downhill sloping groove 23 is prevented by the contact of the stopper piece 4 and the top end of the tray 3.</p> |
