Abstract

PURPOSE: To surely correct the position deviation of an original with simple construction by detecting the deviation normal to the advance direction of the original with the original position detector provided on a circulating course and deviating a printing cylinder by the detection signal thereof.
CONSTITUTION: At the normal time, a solenoid 112 is held energized to maintain a printing cylinder 3 in a central position. If an original deviates to the right R and when a detector detects this, the solenoid 112 is de-energized at the time when the leading end of the original passes the detector, by which the printing cylinder 3 is deviated slightly in an L direction. Thence, when the trailing end of the original is detected with a microswitch, the solenoid 112 is again energized to reset the printing cylinder to the central position of the figure. If the deviation of the original to the left L is detected with the detector, a solenoid 113 is energized at the time when the leading end of the original passes the detector, by which the printing cylinder 3 is deviated slightly to a right direction. In this way, the position deviations of the original are surely corrected by the simple construction.
