<p>PURPOSE:To smooth the movement of a moving body and to improve its operability by moving a cassette moving body with the movement of a guide projection running along the cam groove of a gear and by the interlocking of an elastic part provided on the cam groove and a switch. CONSTITUTION:The elastic part 41 is formed between a groove 27b and groove 40 at the maximum radius of curvature side of the cam groove 27 of a gear 25 and the projection 30 standing on a driving member 26 slides inside the groove. When the gear 25 is driven in K direction, the projection 30 is guided to the groove 27 and the member 26 is displaced in a discharging direction A2 and the moving body 20 mounting a cassette in an insertion direction A1. The movement amount of the elastic part 41 is smaller than that of the moving body 20 with the interposition of a speed reducing mechanism, a pressing member 49 pushes a switch SW2 prior to the elastic part reaching the maximum deflection amount and the moving body is automatically moved in the insertion direction by lightly pushing it only with the action of the elastic part. Consequently the movement motion of the moving body is smoothed and the operability can be improved.</p> |
