ABSTRACT:
An apparatus for making a color proof having an exposure portion for exposing an image of the original onto a photosensitive material and a processor portion for processing the exposed photosensitive material. The apparatus has a transfer portion for transferring the photosensitive material from the exposure portion to the processor portion, which has a first pair of rollers for feeding the photosensitive material disposed adjacent to the photosensitive material delivery side of the platen portion, a second pair of rollers disposed adjacent to the photosensitive material inlet side of the processor portion at the transfer portion and a guide member for guiding transferring of the photosensitive material from said first pair to said second pair. Also, a sensor is disposed downstream in the feeding direction of said second pair of rollers for sensing the presence of the photosensitive material and a control unit is provided for controlling driving of said first and second pairs of rollers so as to rotate them at equal speeds while controlling driving of the pair of rollers so as to reduce the rotating speed of the second pair of rollers when the presence of the photosensitive material is sensed by said sensor. When the tip end of the photosensitive material is sensed by the sensor, the rotating speed of the second pair of rollers is reduced so as to coincide with the processing speed of the processor portion with the result that transferring of the photosensitive material from the exposure portion to the processor portion is smoothly carried out.
