Claims

[Scope of claim for utility model registration] (1) An image input device that inputs an image of a document while moving the case along the document surface, including a light source that illuminates the document and light that is illuminated by this light source and reflected from the document surface. A reflection plate that reflects light; an image input unit that inputs the light reflected by the reflection plate and converts it into an electrical signal; a rotary body that rotates as the body moves; a protrusion that is provided on the image input unit side of the case and comes into contact with the document when it moves on the document surface; and at least between the rotary body and the protrusion. an image input device, comprising: a control board for controlling the image input unit, which is mounted with a space between the image input unit and the case; (2) Utility Model Registration The image input device according to claim 1, wherein the space is formed by a protrusion that protrudes toward the control board side of the case.
