Abstract

Abstract PURPOSE:To provide an original width detection sensor on the running path of the original to switch automatically the scanning width. CONSTITUTION:Originals different in width are inserted between rollers 31 and 32 in direction 10, and a light is irradiated to one-line components 7 of the picture just before rollers 41 and 42. The reflection light is focused onto photodetector 9 by lens 8 to obtain a binary signal. Sensors 51 and 52 and sensors 61 and 62 are arranged between rollers 31 and 32 and rollers 41 and 42. The scanning width of photodetector 9 is switched by the detection signal of these sensors, and switching is performed for expansion, reduction, or the original size of the original width. As a result, the scanning width can be switched automatically according to the original width.
