<p>PURPOSE:To reduce the operating force with mechanical means, by operating the delivery member in interlocking with the follower rotating body and operating the operation member corresponding via the self-return type insert. CONSTITUTION:The large gear 17 biased to be engaged with the pinion 16 being the driving source is possible to latch and unlatch to and from the pinion 16 with the detent member 13, the detent member 13 is removed from the large gear 13 by manual operation of a plurality of self-return type inserts 7 provided corresponding to each operation member 3, allowing to engage the large gear 17 and the pinion 16. In this case, the operaion member 3 is held at reciprocating position, and the insert 7 held at lowering position with the release member 10 is unlatched from the detent ridge 10d with the operation of the operating member 3, and the operation member 3 and the insert 7 are both restored upward, allowing the selected operation.</p> |
