Original deviation correction device of copying machine

Abstract

Abstract PURPOSE:To prevent a lateral shift between an original and photosensitive paper by correcting the deviation of the original in repeat copying until the reference end of the photosensitive paper is aligned to that of the original without reference to the deviation of the original. CONSTITUTION:An original-deviation detection sensor 45 measures the left and right extents of the deviation of an original, being fed back in a repeat carriage path, from a reference position and the direction. The signal of the sensor 45 is inputted to an arithmetic control part 111 to transmit pulses equivalent to a difference between the extent of the deviation of the original and the extent of the deviation of a cassette table at that time to a motor 108. Consequently, the motor 108 turns by the extent which corresponds to the number of pulses until the reference end of the photosensitive paper mounted on the cassette table 101 is aligned to the side edge of the original on the repeat carriage path.
