ABSTRACT:
An original reading apparatus can realize stepwise or sequential variable magnification using relatively small size optical system upon reading an original. The apparatus includes a first mirror arranged in an optical path from a reading position of an original to an image forming portion across an image forming lens and reflecting a light from the reading position of the original, and a second mirror arranged with placing a reflection surface in opposition to a reflection surface of the first mirror and reflecting a light reflected from the first mirror for a plurality of times between the first and second mirrors, and thereafter reflecting toward the image forming lens. A mirror angle positioner for varying an angle of the reflection surface of at least one of the first and second mirrors depending upon a designated original reading magnification.
