Abstract

PURPOSE: To prevent paper jam in a recording paper conveying line by beforehand detecting the posture of recording paper having the possibility of causing trouble such as paper jam in image pickup units and removing such recording paper from the conveying path.
CONSTITUTION: Six sets of CCD image pickup units 191W196 each set consisting of three pieces are disposed in the respective portions of the main part of a recording paper conveying path, and four sets of paper guides 181W184 are disposed in a feed path and two sets of paper guides 185W186 in a discharge path. When deflecion or skew is detected by the respective image pickup units 191W196, the respective paper guides 181W186 turn to the alternate long and two short dashes line positions around the turning shafts, thereby guiding the recording paper to the direction of an abnormal discharge path 20 or a abnormal discharge tray 24. Here, the controlling of the copying operations of the respective mechanism parts is accomplished by the 1st microcomputer system constituting a middle size control unit and the controlling of the reading of the image pickup units and the cntrolling of the turning of the paper guides are accomplished by the 2nd microcomputer system newly added.
