Abstract

PURPOSE: To make possible the checking of feeding of a film by providing a light emitting means and a photodetecting means disposed in the relative positions sandwiching film perforations and so arranging the device that the focal plane shutter does not hamper the incidence of rays during light emission operation.
CONSTITUTION: An opening 1b is provided to the guide plate 1a on the lower side of the passage of a film 4 of a camera body 1, then a light emitting element 6 is provided facing the opening 1b in the camera body and a photodetector 7 on the back of the opening 5a opened in a film pressure plate 5. The rays emitted from the light emitting element 6 pass said opening 1b, pass the perforation 4a of the film 4 and pass the opening 5a of the pressure plate 5 then enter the photodetector 7. With such a constitution, the pulse signal as shown in W of the figure is generated in the photodetector 7 every time when the film 4 is fed and its perforation 4a passes between the openings 1b and 5a.
