PURPOSE:To switch a P-P mode to/from an N-P mode with a very simple constitution by providing a means, which selects the operation of blank exposure in accordance with setting of a cartridge which selects a copy mode, and a means which switches process conditions to process conditions suitable for the copy mode. CONSTITUTION:When a film of the negative original is set and is processed in the N-P mode, a cartridge 13 having a developing device 17 in the P-P mode is replaced with a cartridge 13' having a developing device in the N-P mode. A cam 52 inclined in the depth direction of the cartridge is attached in a position under a shutter 37 on the outside of the cartridge 13'. When the cartridge 13 is inserted along a rail 28, the cam 52 pulls up the shutter 37 to such position that the shutter 37 overlap a light shielding plate 36, and the shutter 37 closes the optical path from a lamp 19 to a reflective face of the light shielding plate 30. |
