Summary:PROBLEM TO BE SOLVED: To prevent erroneous photographing and photographing irregularity from occurring by housing a film drawn out from a cartridge in a temporary housing part and guiding the leading edge part thereof toward the downstream side from the upstream side of the temporary housing part. SOLUTION: The whole of the already exposed film F is drawn out from the cartridge 20 and temporarily housed in the film temporary housing part 12. The housing part 12 is provided with a pair of unwinding rollers 42 for unwinding the film F from the cartridge 20, a pair of intermediate rollers 44 for carrying the film F unwound by the rollers 42 and a pair of feeding-out rollers 46 feeding out the film F temporarily housed in the housing part 12 to a developing processing part 14 side. Since the film F is drawn out from the cartridge 20 and housed in such a way, it can be always fed at a fixed speed regardless of the change of the drawing-out resistance thereof from the cartridge 20. Thus, the developing irregularity and the erroneous developing are prevented from occurring.
