PURPOSE: To enable safe and smooth feeding of a film with simple constitution without nipping the photographed film between rollers by providing a means for letting off the film and a means for controlling the rate of letting-off according to the change in a housing position.

CONSTITUTION: The unphotographed films 20a, 20b are taken out of magazines 21a, 21b in a film changer 1 and are gripped by the clip 26 at the front end of a moving belt 25 let off from a drum 24. The films are conveyed toward a position (d) direction and are subjected to image pickup in the position of a photographing stage 31. The photographed films are housed into a magazine 21c or changed over by a guide plate 51 and are conveyed to a connector 2. The films fall by gravity and are fed via a belt 17 to a developing machine when the clip 26 is opened by an opening/closing member 63. The change in the height of a changer 1 when arises is detected by a light emitting diode 61 to control the rate of letting-off of the belt 25. The films are thus sandwiched and conveyed by the belt 25 and are therefore prevented from being pressed by the rollers and the generation of fogging flawing is prevented.
