PURPOSE:To omit a reduction mechanism used for the determination of a stop in a motor-driven camera by utilizing driving loads of a mirror and a shutter as braking factors. CONSTITUTION:A motor 30 rotates counterclockwise according to the operation of a release. At that time, a film system is not moved becaused of one- way clutch. The rotation of the motor is utilized for mirror-up, stopping and shutter charging through a worm 58, worm gears 59, 60 and gears 70, 124. A stop determination means consists of a locking pawl which controls the rotation of a lever 80 by an electromagnet through an over-drive gear. Since each load of the shutter charging performed only by mirror driving and release operation is utilized as a reduction factor, another load is made unnecessary. |
