Abstract
An image reader includes an illumination unit that irradiates an object to be read with light, a first optical system that allows a first reflection light from the object to be read advance therein, a second optical system that allows a second reflection light from the object to be read to advance therein, a switching unit that switches between the first optical system and the second optical system to be used, an imaging unit that forms an image of the first reflection light that advances in the first optical system and an image of the second reflection light that advances in the second optical system by switching between the first optical system and the second optical system by the switching unit, and a light receiving unit that receives the first reflection light and the second reflection light which are formed into images and generates respective image signals.
