PROBLEM TO BE SOLVED: To provide a film sucking means of simple constitution. SOLUTION: When a rear lid is closed, a solenoid 41 momentarily protrudes to lock a stop shaft 36 to a descent end, a film winding stop ratchet 44 retracts from a film winding stop ratchet wheel 30, and a pump stop ratchet 46 locks a pump stop ratchet wheel 31. At the same time, a motor 21 is driven and a film take-up driving gear 36 on which a planetary gear 27 is pivoted drives a film take-up gear 33 through a sun gear 35 and the planetary gear 27 to wind a film; when the film is wound by a prescribed quantity, the solenoid 41 operates to lock a film winder and a vacuum pump 36 operates to suck the film to a pressure plate. When exposure is carried out in response to release operation, the solenoid 41 operates and the film is released from being sucked and then wound. COPYRIGHT: (C)2004,JPO
