Abstract

PURPOSE: To improve slanting detecting accuracy even if it is a kind of longitudinally long sheet of paper in such a way that a sheet lateral part detector is provided on the conveying passage of sheets of paper for a duplicator or the like in order to detect the displacement rate of the position at the lateral part of the sheets of paper.
CONSTITUTION: A photosensor 35 and a lamp 34' which faces opposite to it are provided so as to sit astride on the lateral part traveling reference line of a guide 36 to convey the paper which comes out of a registroller 33. The photosensor 35 gets light receiving elements arranged by n-pieces of determined pitches, detection is done on the passing paper whether light is received until the receiving element at which position in order to detect displacement from the reference line and to compare it with the determined value, and when displacement more than the determined value is detected, a conveying change-over piece 44 moved, and the sheet of paper which has larger displacement is taken out of the system 44. This reference line is put in common with the lateral part of the paper in each size. By this constitution, one piece of the sensor will do, and the displacement detecting accuracy is improved for the sheets of paper B4, A3 which are longitudinally long.
