Abstract

PURPOSE: To omit a needless return operation and make the read speed high and prevent early waste of the mechanical movable part, by providing a read means which can read the original in normal-direction as well as reverse-direction scanning.
CONSTITUTION: When slit illumination dependent upon lamps 8a and 8b is moved from the left to the right on the surface of original 2 on original stand 1, the original picture is read through lens 9, switching mirror 10 and the second mirror 11a by photosensitive drum 12a to form a latent image. After the completion of scanning from the left to the right, switching mirror 10 is rotated at 90° and is placed in the position shown by the dotted line; and when slit illumination is moved from the right to the left on the surface of original 2, the original picture is led to photosensitive drum 12b, which is rotated in the direction opposite to photosensitive drum 12a, through lens 9, switching mirror 10 and the second mirror 11b to form a latent imge.
