PURPOSE: To facilitate the removal of a photosensitive material clogged when a jam arises particularly at the carrying path of an exposing position and to facilitate pin adjustment, cleaning and exchange by constituting a photosensitive material supplying section unit, an exposing section unit and a processing section unit in such a manner that these units can be opened and closed.

CONSTITUTION: The photosensitive material supplying section unit 12 and the exposing section unit 14 are so constituted that the units can be opened and closed with respect to the processing section unit 16. The photosensitive material supplying section unit 12 can be opened from the device body 11 by turning the same clockwise around a pin 102 if the jam arises. Since the exposing section 28 and carrying guide are opened from the centers thereof at this time, the photosensitive material clogged by the jam can be easily removed. The easily removal of the clogged photosensitive material is possible if the processing section unit 16 is opened by rotating and moving the exposing section unit 14 upward around the pin 62, even when the jam arises in the processing section 17 and drying section 18 in said unit 16.
