ABSTRACT:
In a camera having a stop drive mechanism adapted to be driven by an electric motor to vary a stop aperture and a film wind-up mechanism adapted to be driven by the electric motor to wind up a film, the electric motor is rotated to drive the stop drive mechanism before exposure of the film, and it is also rotated to drive the film wind-up mechanism after the exposure of the film. The rotating speeds of the electric motor in the first rotation to drive the stop drive mechanism and in the second rotation to drive the film wind-up mechanism are independently variable.
