Abstract

PURPOSE:To simplify the construction of a detector for film holes by attaching a light receiving element and a light emitting element to the body of a camera to detect film holes. CONSTITUTION:A film 5 is shifted through a space between an external rail 1a of the body 1 of a camera and a pressure plate 3 fixed on the back cover of the camera through a flat spring 4. A hole 1c of the body is installed to the position opposing to the hole 5a of the film 5. A light emitting element 6 and a light receiving element 7 are disposed to the body 1 so that the light from the element 6 irradiates the film 5 through the hole 1c and the reflected light is made incident into the element 7 through the hole 1c. Thus, the construction of the detector for the film hole 5a can be simplified.
