PROBLEM TO BE SOLVED: To easily remove recording material by providing a lock means for inhibiting the opening action of a shielding means while a carrying means for carrying the recording material is being operated. SOLUTION: When the movable iron core 29b of a front panel lock solenoid 29a is fitted in the lock hole 29c of a perpendicular part 6a, a front panel 6 being the shielding means covering the carrying path of a photosensitive material is locked. When the fit iron core 29b is withdrawn from the lock hole 29c, the lock of the panel 6 is released. When the panel 6 is locked, it can not be opened, and a hand is not inserted in a jamming processing window part 38. When the lock is released, the panel 6 can be opened, and the hand is inserted from the window part 38. The window part 38 has a form by which the hand reaches over a mechanism along the feeding path, that is, the paper supply part of an exposure unit and a 1st paper ejection part, so that work to remove jammed paper can be performed.
