Claims

[Scope of utility model registration request]

A document glass on which a document is placed, a traveling body that moves parallel to the document glass in sub-scanning, a lamp mounted on the traveling body to illuminate the document, and a mirror that forms an imaging surface in the main scanning direction. In a document reading device including a 1-magnification imaging element including a system and a light receiving element disposed on the image forming surface, a first contact surface that contacts the document glass; providing a jig for adjusting the mounting height and position in the optical axis direction of the same-magnification imaging element, including a second contact surface that contacts the light-receiving element mounting surface on the traveling body;
An optical system position adjustment device characterized in that the traveling body is provided with a fine adjustment means for finely adjusting the light receiving element attached to the light receiving element mounting surface in the sub-scanning direction after the jig is removed.
