Abstract
An image reading apparatus includes a sensor IC having a group of photoelectric conversion devices which are linearly aligned, a sensor board on which the sensor IC is mounted, a lens for forming light information into an image on the sensor IC, a light source having electrical connection lines, an illumination unit consisting of a light guide for guiding light from the light source and outputting the light in a desired direction, and a frame for holding the respective members. The electrical connection lines of the light source are directly connected to the sensor board. Connector cables for the light source can be omitted, and the image sensor and the external system can be electrically connected through one connector. By simplifying the electrical connection, the influence of noise can be minimized.
