Original image reading apparatus having device for conveying an original at a position deviated from an original reading position of a contact-type reading sensor

摘要

An original image reading device includes a first supporting device having an original platen roller, provided on a side of an original opposed to an image reading device, for conveying the original at a position deviated from an original reading position, and a non-cylindrical original contact device for urging the original toward the image reading device. The original contact device is provided at the original reading position on the side of the original opposed to the image reading device. A second supporting device includes the image reading device, which has a contact-type reading sensor. The image reading device reads image information of the original by receiving a light reflected from the original. The first supporting device and the second supporting device are combined at a fulcrum at an original exit side so as to relatively rotatable. The original platen roller is separated from the second supporting device upon relative rotation of the first and second supporting devices.
