PURPOSE: To keep the planeness of a film surface for photography and prevent the damage of the film surface for winding, by providing a press plate, which is movable in the direction of the optical axis and is formed with a magnetic material, near the film surface between a supply chamber and a winding chamber and operating this press plate by an electromagnet.
CONSTITUTION: In case that a film cassette is loaded in an endoscope camera, a press plate 34 which is connected by curved elastic supporting members 35 and 36 is placed near a mirror 40 in the rear of a photographic lens 39, and an electromagnet 37 is provided in the same plane as the front of a frame material near the rear side of a film 31. When the film is wound and a rear cover is opened, a switch 38A is turned off, and a current is not supplied to the electromagnet 37, and the film surface is held in the unpressed release state; and when the photographic preparation is completed by the winding lever operation, the switch 38A is turned on, and the press plate 34 is attracted to the electromagnet 37, and the film surface holds the planeness.
