Abstract

PURPOSE:To hold flatness of an original and to carry it exactly in case when a lot of sheets are copied, by using an original detecting device, switching a rotary direction of a carrier roller, and executing the reciprocating motion of the original. CONSTITUTION:The first and second carrier rollers 4, 5 are placed on the surface side of contact glass 10, and the first and second detecting devices 22, 23 consisting of a light emission element and a photodetecting element are provided on the lower side of the glass 10. In this constitution, when the rollers 4, 5 are rotated clock- wise, an original is carried to the left, prescribed copying is executed, and when the rear end of the original is detected by the second detecting device 23, the rollers 4, 5 are stopped once, subsequently are rotated counterlockwise, the original is moved to the right, and when it is detected by the first detecting device 22, it is shifted in the opposite direction over again, and its reciprocating motion is executed. In this way, in case when a lot of sheets are copied, flatness of the original is held, and it is carried exactly.
