Abstract

A sensor unit and LEDs are arranged on a sensor board. A light guide is placed above the resultant structure to be parallel with the sensor. The two end portions of the light guide are bent downward at right angles, and the bent end portions serve as incident portions on which light beams from the LEDs are incident. Light entering the light guide emerges from an exit portion to be irradiated on an original. The light reflected by the original is read by the sensor. The direction in which the reflected light is incident on the sensor is parallel with the direction in which the light from each LED is incident on the incident portion. With this structure, in the image sensor, electrical connection between the LEDs, the sensor unit, and an external system is facilitated.
