ABSTRACT:
A motor driven camera in which a reversible motor is used to wind and rewind the film, and to perform some reciprocative camera function. The camera is constructed so that film will be wound in the forward direction of the motor. The reciprocative camera function is performed by reversing the direction of the motor. An additional shifting step is necessary to rewind the film, the film being rewound when the motor is in the reverse mode and the shifting step is completed. Examples of reciprocative camera functions include lens focus, and retracting a flash or lens cover.
