Abstract

PURPOSE: To keep the correction free from friction of a roller or the like by automatically adjusting the inclination of a paper reversing guide member according to a skewing signal.
CONSTITUTION: When a paper skews, leading end detecting signals (a), (b) having a time difference therebetween turn into a paper detecting signal (c) through OR gate, and turn into a clock signal (g) through a delay 13, AND gate and OR gate. Simultaneously it turns into clock signals (g), (h) of lagging time tn+1 corresponding to a permissible paper skew determined by a variable resistance 10. By these clock signals, when a time difference between the signals (a), (b) is more than a permissible quantity tn+1-tn, outputs of latch circuits 25, 26 turn into skew correcting signals (s), (t), so that a guide member in moved corresponding to the skew so as to correct skewing.
