Abstract: An image reading apparatus capable of easily detecting the width of a document is provided that can reduce the number of component parts. A surface to be detected of a moving section that moves in linkage with the movement of a document guide is detected using an image pickup device, so that the width dimension of the document is detected. This allows the image reading apparatus to detect the width dimension of the document by using the image pickup device.

Abstract: In an image reader that can adjust a distance between a platen glass and a close-contact-type image sensor (CIS) without disassembly, a CIS unit includes a CIS and a resilient body which biases the CIS toward the platen glass. A CIS roller holder includes a spacer, and a CIS holder which holds the spacer movably in the vertical direction as well as in the sub scanning direction with respect to the platen glass and is fixed to the CIS unit. Irregularities are formed on surfaces of the CIS holder and the spacer which face each other and are engageable by fitting. When the CIS unit is moved in the sub scanning direction and the CIS roller holder is brought into contact with one rib ,the CIS roller holder is brought into contact with the spacer at projections or recesses, thus changing a distance between the platen glass and the CIS.
