Claims

[Scope of Claim for Utility Model Registration] 1. Slit exposure is performed while a light source provided along the document width direction is moved and scanned along the document surface by a driving body of a drive unit, and the light reflected from the document surface is used as a primary light source. An image input device that reads the contents of a document by inputting the original line sensor, and is an optical unit that houses an optical system having a first mirror, a second mirror, an imaging lens, the one-dimensional line sensor, etc. A carriage is formed by stacking and integrating a signal processing unit containing a signal processing system having a signal processing circuit etc. connected to the one-dimensional line sensor, and movement of this carriage. Among both side surfaces parallel to the direction, the width of the driven surface connected to the driver side is longer than the width of the auxiliary surface located on the opposite side to the driven surface, and An image input device characterized in that the center of gravity of the carriage is biased toward the driven surface side rather than the auxiliary surface side. 2. The image input device according to claim 1, wherein at least an imaging lens and a one-dimensional line sensor of the optical system are disposed at a position close to a driven surface within the optical unit.
