<p>PURPOSE:To perform loading, and mode shift with one motor, and to attain the miniaturization and low cost of a device, by meshing at least two geneva gears with a main gear, and converting the continuous rotation of the main gear to the intermittent rotation of the geneva gears. CONSTITUTION:The rotation of the motor 15 capable of rotating in a forward and a backward directions is transferred to the main gear 24 by a prescribed power transmission system. The main gear 24 is meshed with the geneva gears 25-27. And on the main gear 24, a cam plane 24b and an intermittent gear part 24c are formed, and a cam plane 25b and an all-around gear part 25c are meshed with those parts, and the similar constitution is adopted at the other part. In this constitution, the gears 25 and 26 are rotated intermittently with a prescribed timing by rotating the gear 24 continuously by the motor 15, then, the loading is performed, and the mode shift is performed by the intermittent rotation of the gear 27, therefore, it is possible to perform an operation for which two driving sources are needed in a conventional method, with one motor, and to miniaturize the device and to lower cost.</p> |
