Patent number: 7391541Abstract: It is an object of the present invention to provide an excellent image reading apparatus that realizes miniaturization and reduces a total reading time at the time of reading a transparent original and, in addition, improves operability. In order to attain this object, since the image reading apparatus has a configuration in which a light source driving circuit section is disposed to overlap in the upward direction separating from an original mounting surface of a surface light emitting section, an area occupied by the light source driving circuit section and the surface light emitting section on a horizontal surface becomes small and miniaturization can be realized. In addition, since the light source driving circuit section and the surface light emitting section can be disposed in a position close to a hinge section altogether, the center of gravity of an FAU is moved to the hinge section side, and rotatability of the hinge section becomes easy and is improved.Type: GrantFiled: July 6, 2005Date of Patent: June 24, 2008Assignee: Canon Kabushiki KaishaInventors: Toshio Takahashi, Naofumi Sekine, Hideyuki Fujiwara, Kenichi Nanpei
