PURPOSE:To perform exposure and development by one set, and to reduce occupation area and eliminate the need to align and superpose negative paper and positive paper one over another, by mounting a developing device equipped with a dual-system transfer system, a developing tank, a squeezing roller, and a diffusion transfer chamber. CONSTITUTION:The limit switch 59 of a negative material transfer system 40 is normally off, and a clutch is connected in the ON state wherein an actuator 59a is pressed to drive a couple of roller shafts on the upstream side of the limit switch 73 of a positive material transfer system 60. Positive material inserted into the transfer system 60 precedently stops once the actuator 73a of the limit switch 73 is pressed and then enters a stand-by state. Then, the exposed negative material is inserted into the transfer system 40, and when the actuator 59a of the limit switch 59 is pressed, the tranfer of the positive material is restarted synchronously to insert those negative material and positive material into the developing tank 80 while aligning the slightly precedent negative material to the positive material. |
