Abstract
Controlling of film winding-up and film rewinding are carried out responding to an insertion of film, open and close of the back lid of the camera and moving of the film; and the motor is stopped when the status of the camera operation is abnormal, such as film is not filled or film is caught or the back lid is not completely closed; and when the film is set and back lid is closed, the film is automatically wound up to the position of the first frame photographing by a half-pushing of a shutter release button, thereby eliminating necessity of the film frame number counter or the like; by quick stopping of the motor at abnormal states, waste of power source current due to motor over current is eliminated.
