Abstract

PURPOSE: To obtain a small-sized and economical apparatus by allowing the advancing and retreating action of the first shaft and the turning operation of the second shaft to be executed in relation to each other by a driving apparatus.
CONSTITUTION: When a motor 16 is revolved in normal direction, the first shaft 1 rises-up, revolving along the screw hole of a fixed member 13. The revolution of the first shaft 1 is transmitted to the second shaft 19 through a pinion 9 and a sector gear 25. When the terminal edge area of the tooth 25a of the sector gear 25 is engaged with the pinion 9, the top edge of a bolt 29 contacts with a stopper 30 and shifts it against the exerting force of a spring 32. When the first shaft 1 rises-up further, the engagement of the sector gear 25 and the pinion 9 is released, and the concave area 25b of the sector gear 25 is engaged with a tapered sleeve 10. As a result of this, the sector gear 25 revolves in the direction of arrow A little by little against the exerting force of the spring 32.
