Abstract

PURPOSE:To display the number of the residual frame of a film by providing a total film number detector which detects total film frame number information, a frame number setting device which sets the number of frames in accordance with the feed per frame of the film by a frame feeder, etc. CONSTITUTION:A film residual frame number display device has a reflection type photocoupler as a total film frame number detector consisting of a pair of a light emitting element 70 and a photodetector 72 provided on the leading end surface of a projecting part 69. The light from the element 70 of which the quantity of light is defined is entering the element 72, where it is converted to an electric signal corresponding to the quantity of incident light. Hence, the information on the total number of film frames is detected with the detectors 70, 72, and this value and the number of frames detected from a frame number plate 96 rotating cooperatively with the winding operation of a photographing film 46 are refered to substrahends to subject to substraction operation, whereby the residual number of frames of the film is displayed.
