Abstract

PURPOSE: To correct easily a shift in the read position of picture information in a subscan direction by providing a linear mark in parallel to the movement direction of an optical system outside the effective read region of contact glass.
CONSTITUTION: An original is mounted on contact glass 11 and optical system 16 is moved to read mark 20 together with picture information by solid scan element 15 at the same time. On the basis of the picture signal of mark 20, picture information a fixed number of bits after is transmitted as effective picture information and rewritten. Therefore, when the movement of optical system 16 is uneven, it can easily be corrected.
