Image reading apparatus including two irradiation units that irradiate with light

Abstract

An image reading apparatus includes: a reading unit configured to read a document being conveyed on a conveyance path, the reading unit including a first irradiation unit configured to irradiate with light from an upstream side of a reading position of the reading unit toward the reading position in a conveyance direction of the document, and a second irradiation unit configured to irradiate with light from a downstream side of the reading position toward the reading position; and a control unit configured to control light emission of the first irradiation unit and the second irradiation unit such that a light quantity by the first irradiation unit is larger than a light quantity by the second irradiation unit in a first range in a range of the conveyance path in a width direction orthogonal to the conveyance direction.
