Abstract
A reading module includes: a light source for applying light to a document; an optical system for forming an image as image light from reflected light of the light applied from the light source to the document; and a sensor in which a plurality of sensor chips for converting the image light formed by the optical system to electric signals are disposed in adjacency to one another in a main scanning direction. The optical system includes: a mirror array in which a plurality of reflecting mirrors whose reflecting surfaces are aspheric surfaces are coupled in array in the main scanning direction; and apertures provided between the reflecting mirrors and the sensor chips, respectively, to regulate light quantity of the image light reflected by the individual reflecting mirrors. The specular-surface number of the reflecting mirrors is set to an integral multiple of the number of the sensor chips.
