To provide a printer processor whose the cost is low, whose the production cost is reduced, where an entrance guiding slit guide and a developing processing part cover are simultaneously detached, whose the maintenance is facilitated and where jamming processing is easily performed by providing the developing processing part cover with the entrance guiding slit guide of a developing processing part.
This developing processing part cover 690 with which the upper part of a developing processing part is covered is installed at the upper side of the developing processing part. The cover 690 is provided with an entrance guiding slit guide 695 for putting a photosensitive material for printing exposed at an exposure part in the developing processing part. The guide 695 guides the photosensitive material for printing passing through a switchback mechanism downward nearly in the vertical direction to put it in the developing processing part by guiding the leading edge of the photosensitive material to a press-contact part of a pair of entrance carrying rollers of the developing processing part by a tapered surface where the switchback mechanism side is made wide.
