Abstract
PURPOSE: To produce driving torque corresponding to large load torque at the releasing of slip joint for wind transmitting the driving torque of a spring motor by way of a variable angular velocity ratio transmission mechanism.
CONSTITUTION: When the torque is transmitted to a wind transmission mechanism via the slip joint constituted by a charge lever 104 and cam 106 by the energizing force of the spring 8 of a spring motor 6 through turning of a charge knob 1 and winding of film and shutter charging are thereby performed, then the transmission of the driving torque is stopped by means of a control lever 22 and the pin 11a of a wind stop control gear 11. When this stopping is released by way of a magnet 33 which is energized after shutter operation, the torque is similarly transmitted via variable speed transmission mechanism, etc. by oval gears 101, 102 and the torque being applied to the lever 104 becomes maximum. Hence, the lever 104 goes over the protrusion part 106a of the cam 106 according to large load torque and the slip joint is released upon completion of winding, thus smooth releasing may be performed
