PURPOSE:To enable forward driving and reverse driving by one driving motor by providing a three-system output distributing means which transmits forward and reverse driving outputs from the one reversible driving motor, an output distribution control circuit, and an arithmetic circuit which performs arithmetic operation required for control. CONSTITUTION:Three photographic functions, i.e. displacing operation for a photographic lens 1 capable of automatic focusing, operation required to realize exposure wherein the brightness of an object and a shutter speed value and a numerical aperture are realized automatically, and film feeding operation for winding and rewinding a film automatically are all automatized or motor- driven. For this purpose, the rotation output from the one electric motor 33 capable of rotating forward and reversing is distributed to operation member 209, 225, 342 ... which enable the three phtotographic function to be effected independently of one another in specific order principally by the three-system distributing means 20b to carry out the three photographic function operations with the forward and reverse rotation outputs of the electric motor 33. Thus, the forward driving and reverse driving are performed by the single driving motor.
