Abstract

An image reading apparatus includes a contact type image sensor device optically reading the document, a platen roller pushing the document against a surface of the image sensor, a flame supporting the contact type image sensor device. The flame has a mounting surface to which the contact type image sensor device is fixed and a side wall which rise from the mounting surface in the vicinity of the contact type image sensor device. A gap is formed between the contact type image sensor device and the side wall. The image apparatus also includes a filling agent filling the gap including substantially spherical particles having an anti-friction characteristic.
