<p>PURPOSE:To increase the manipulation, by reducing the operating force with the mechanical means, through the provision of a plurality of self-return type insert between the delivery member and the operation member. CONSTITUTION:In the manual operation unit selectively operating a plurality of operation members 3, one delivery member 6 is pivotally borne to the fitting shaft 2 to which each operation member 3 is pivotally borne with reciprocation-free, and this delivery member 6 is provided with a plurality of inserts 7 corresponding to the operaion member 3 as the self-return type in slide-free up and down directions. When the push button of reproduction or recording is selected and depressed, the insert 7 is correspondingly depressed as the arrow 9 downward, the interruption part 7b is interrupted between the delivery member 6 and the operation member 3, and the delivery member 6 turns counterclockwise with the insert 7 held, resulting in meshing the large gear 13 with the pinion 12 and closing the switch 26 at the same time.</p> |
