PURPOSE:To shorten a feeding time for driving power supply and to reduce power consumption by providing a shutter opening/closing means with a latching means for holding the opened state of a shutter at the time of carrying a photosensitive material. CONSTITUTION:When the tip part of the sheet-like photosensitive material reaches the position of a sensor 20 at the time of carrying the material, power supply is inputted to a solenoid 27 and a latch plate 31 is rotated in the counterclockwise direction by the driving of the solenoid 27. When the latch plate 31 is rotated, its supporting claw part 31a is abutted upon a roll 32 and the shutter 23 is lifted upward through a supporting pin 34. The opening operation of the shutter allows a bending part 31b of the latch plate 31 to be abutted upon a guide part 35b of a hook 35 and the hook 35 is pressed against a coil spring 37 by the rotation of the latch plate 31 and rotated in the clockwise direction. Since the shutter is held at the opened state at the time of passing the photosensitive material, it is unnecessary to supply power to the shutter opening/closing means and hold the carrying route of the photosensitive material at the opened state.
