Abstract
PURPOSE: To enable alarm to be displayed with good efficiency by providing plural display elements displaying film feed states and when normal feeding does not take place, flickering the display element corresponding to that feed rate.
CONSTITUTION: Light emitting diodes D6WD10 associating to the display windows 6W10 displaying the feed state of a film are connected respectively to a film state detecting circuit C via a sliding switch S2 moving according to the feed rates of the film. When a film cartridge is inserted into the camera, a switch S3 opens and a detecting switch S4 gones on and off in response to the revolutions of the winding shaft for the film. The consuming state of the film is displayed by lighting of the light emitting diodes D6WD10 through a display window. When the feeding of the film stops on account of a fault, the detecting switch S4 does not turn on and off; therefore, any of the light emitting diodes D6WD10 is displayed by flickering, whereby the alarm is emitted.
