<P>PROBLEM TO BE SOLVED: To provide an integrally formed scanning optical unit, an image read-out device, and an image forming device that can realize mirror arrangement efficiently and downsizing. <P>SOLUTION: In an integrally formed scanning optical unit 301, an image sensor 404 is mounted on a substrate 405 provided at one end side of a sub-scanning direction in a state of extending in a direction perpendicular to a document surface, an illumination unit 401a of illumination units 401a and 401b is provided above a substantially same plane of the substrate 405, a reading optical axis perpendicular to a reading position A for reading a document 406 is provided so as to close to one end side from a center of the sub-scanning direction, and the document 406 is irradiated by the illumination units 401a and 401b from both sides of the sub-scanning direction holding the reading optical axis in-between. <P>COPYRIGHT: (C)2013,JPO&INPIT |
