Original reading apparatus

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. Reflection times setting means sets number of times between the first and second mirrors by varying an angle of the reflection surface of at least one of the first and second mirrors depending upon a designated original reading magnification.
