メラの誤撮影防止装置。 In a pre-winding camera that switches to a shooting mode that rewinds the film one frame at a time into the cassette after a pre-winding mode in which the film is pulled out from the cartridge, the presence or absence of the film on the film feeding motor and the aperture surface is detected. a film detection switch that detects the presence of a film, and a feed switch that operates in conjunction with the rotation of the film feed motor to output a signal corresponding to the film feed when the film detection switch detects that a film is present. , a mode detection switch that switches according to the pre-winding mode and shooting mode, and when this mode detection switch detects the shooting mode and the film detection switch detects that there is film, the feed switch a counter for counting the signals; a film frame number determining section for determining from the counted value of this counter whether or not a prescribed number of frames have been photographed; and when the frame number determining section determines that a prescribed number of frames have been photographed. A device for preventing erroneous photography of a pre-winding camera, comprising a release prohibition part for prohibiting the camera from being released.
