<p>PURPOSE:To divide power from a single driving source to plural transmission systems and to reduce the size and weight of a timing control mechanism without any other motor dedicated to switching, etc., by providing three systems composed of a driven part, etc., and a power transmitting mechanism consisting of a sun gear, a planetary gear, etc. CONSTITUTION:The turning force of a loading motor is transmitted to a gear 6 united with a motor shaft, integrated gears 7 and 8, and gears 9-11. Then, the direction of rotation to a worm gear 13 from a worm 12 united with the gear 11 is changed by 90 deg. and then the force is transmitted from the sun gear 14 united with the worm wheel 13 to the planetary gear 15. a planetary arm 25 is engaged between the gears 14 and 15 and this arm 25 is rotatable through the friction mechanism consisting of a spring and felt interposed between the wheel 13 and gear 14. Then, the arm 25 has its motion controlled by a stopper which is not shown in a figure, and consequently the turning force is transmitted from the gear 15 to one gear 16a of a clutch gear 16 engaging it.</p> |
