Abstract
PURPOSE: To achieve simpler construction by using a planetary gear device as a main power transmission means.
CONSTITUTION: The motion film feed/shutter driving means 1 is constituted by a motor 3, gears 4, 5, a cylindrical film feed member 17 provided with film feed claws 18aW18f, notches 19aW19f, a planetary gear device 16 consisting of a sun gear 6, planetary gears 7W9, internal gear 10 and support body 12, a bevel gear 24 mounted to a shutter shaft 23, ratchet wheel 26 and a bevel gear 22 intermeshed with these, levers 31, 32, a gear 20 fitted to the support body 12, etc. Then, when the motor 3 runs, the film feed member 17 and shutter blade 25 are operated alternately by the planetary gear device 16, etc., whereby photographing is accomplished. The use of the planetary gear device 16 eliminates the need for taking the synchronization of the operation of the film feed member 17 and the operation of shutter blade 25 and the construction is simplified.
