PURPOSE:To provide a convenient mechanism by so constituting the same that a movable part hands and receives a cassette cradle to and from the 1st means in a prescribed position and that the movable part can move together with the cassette cradle between the prescribed position and an operating position. CONSTITUTION:A cassette cradle 3 is in the state that the guide projecting ling part 4a of its side part 4 is held fitted in a guiding groove part 6a. When a pinion 8 is held meshed with the trailing end part of a meshing part 4b and with the leading end part of a meshing part 7d, a driving arm 10 rotates a shaft 9 in the direction where it is forcibly driven backward along a horizontal part 1b'. Along with the backward movement of the shaft 9, the pinion 8 moves backward and as it moves, it rotates with respect to the meshing part 7d which does not move backward. A certain side part of the meshed part 4b meshed with the pinion 8 retreats, that is, the cassette cradle 3 retreats. |
