PURPOSE:To improve the reliability as well as to reduce the time loss for feed of the photosensitive paper, by switching the touch/detouch and the driving speed between the 1st driving part which feeds the photosensitive paper to the exposure part and the 2nd driving part which feeds said paper to the development part respectively. CONSTITUTION:When the heat development type photosensitive paper P is fed to an exposure part, the intermediate wheels 131 and 132 for switching which fixed to a turning shaft 125 are brought into contact with pulleys 140 and 141 of small diameters respectively. Then the shaft 125 is turned by a feed motor 123. Then the pulleys are turned to drive feed belts 87..., and at the same time a feed roller 112 is turned to feed quickly the paper P to the exposure part. When the paper P is fed to a development part 151, the wheels is brought into contact with a pulley 133 of a large diameter and the pulley 141 of a small diameter. The turning shaft is driven at a low speed with turning of the shaft 125. However the pulley 140 and a roller 112 are not turned, and only the belts 87 are driven at a low speed. |
