Abstract

PURPOSE: To enable the sure checking and displaying of film feeding by letting an electric charging circuit and lighting circuit be flickered by the contact member which goes in and out from the perforations of the film.
CONSTITUTION: If a film F is held stopped and the protruding part 10 of a travelling contact member 9 is held fitted onto the perforation P of the film F, the switch S1 of an electric charging circuit 7 is open and a light emitting diode 3 is off. Now, when the film F is wound, the protruding part 10 goes into and out from the hole and land of the perforations P and therefore the switches S1 and S2 repeat flickering, hence the light emitting diode 3 flickers, thereby displaying that the film is being surely fed.
