Abstract
PURPOSE: To control a camera so that the cover part of the camera is made to be opened by a control means and to prevent a film from exposed by the misoperation of a user by judging that the film is completely rewound up in a film case only at the time of detecting that the rotation load of a motor is smaller than a specified value.
CONSTITUTION: The cover part 3, which can freely rotate, is fit on an axis 2 planted on the motor-driven camera main body 1 and it is made to open outside, centering around the axis 2. The motor 5 for automatically winding the film 4 is incorporated in the main body 1. And a pinion gear 18 is fixed on the rotating axis of the motor 5 and the rotation driving force of the motor 5 is transmitted to a roller 6 or a rewinding gear 20 through a deceleration gear group 19 and a clutch mechanism (not illustrated in a figure). A passive reflector 21 is fixed on the one end of the gear 20 so as to integrally rotate and a photosensor 22 consisting of a light emitting part 22a and a light receiving part 22b is arranged on a position opposite to the passive reflector 21. The photosensor 22 works when a main switch 23 becomes on and detects that the load of the motor 5 is smaller than the specified value, then the cover part 3 is made to be opened with the output from it.
