Abstract
PURPOSE: To perform film winding of different loads and shutter release with one set of driving source by changing over a drive transmission system through torque detecting mechanism.
CONSTITUTION: A gear 8 is turned by a motor 1, a torque detecting gear 3b provided with a cam 3c and a gear 4b having a cam 4a, then the shutter is released by the cam 8b and release bar 9. When the motor 1 is restarted upon ending of exposure, the gear 8 is detained by a pin 12 and the gear 4b is raised via the cams 3c, 4c by the braking torque. At the same time, the moving gear 15 cooperating with the gear 14 lowers to couple to an intermediate gear 19, causing the drive transmission system to be changed over and the film to be wound. These gears 14, 15 also detect the torque by the cams, thus the cutoff of the driving torque of the motor 1 at the winding end of the film and the decrease of supply voltage is accomplished.
