PURPOSE:To easily control component position accuracy by driving a mirror driving mechanism and a shutter charging mechanism by the same-directional rotation of one motor, generating a code signal corresponding to a cam phase by a coaxial film for the driving, and controlling a motor with this signal. CONSTITUTION:The rotation of a 1st motor M1 is reduced in speed by a speed reduction transmission system 600 to proper rotation and a planetary clutch 610 is used to switch the rotating direction of the motor 1. Namely, when the motor rotates forward, a shutter charging mechanism 624 and a mirror driving mechanism 622 in a mirror box driving mechanism 620 are put in operation and the phases of their outputs are detected by a phase detecting means 630 and inputted to a motor control circuit 660 connected to the motor M1. In this constitution, the mechanism 624 is provided with a shutter charge cam which is not shown in a figure and the mechanism 622 is provided with an unshown mirror coaxially, and code signals corresponding to the phases of those cams are generated and inputted to the circuit 660 together with the phase signals.
