<p>PURPOSE:To fully take advantage of a manual operation and power drive by constituting such that a projection part and a groove part are interposed between two eject gear parts and the roller of an arm is guided by guide grooves on plates at both sides. CONSTITUTION:When a main holder is inserted into a subholder, it is driven by the eject gear 708, and a loading rack 607 is shifted in the same direction. While the 2nd gear B of the gear 708 rotates by the prescribed angle, its projection part 708d and passes through the groove 708c of the 1st gear A, and therefore drive force never transmits. However, if the main holder is further rotated, the gear A is also driven, and a main gear 704, an arm gear 705 and an arm 611 are rotated. Since the moving quantity per hour of the rack 607 is different from that of the arm 611, a roller 750 loaded in a groove 611 in the arm 611 is moved along the guide groove on the plates at both sides, whereby the moving quantity of the main holder is coincident with that of the subholder. Accordingly the advantages of the manual operation and power drive can be fully utilized.</p> |
