Image reading apparatus and image forming apparatus comprising a first wall, a second wall, a harness interposed between the first wall and second wall, a third wall, the harness not interposed between the first wall and third wall, and a plurality of fourth walls spaced apart from each other extending in an orthogonal direction orthogonal to the first direction in which the first wall and the third wall extend and protruding upward from the bottom of the harness accommodating portion

Abstract

An image reading apparatus is provided, including a platen glass having opposed upper and lower surfaces, a support frame supporting a peripheral portion of the platen glass, a reading device reciprocable in a first direction and disposed on an inner side of the support frame so as to be nearer to the lower surface than to the upper surface, a guide formed on an inner bottom surface on the inner side of the support frame and extending in the first direction so as to guide reciprocation of the reading device, a controller that controls operations of the reading device, a harness connecting the reading device and the controller to each other, and a harness accommodating portion accommodating the harness and constituted by a groove having a recessed shape, extending in the first direction, and formed at the inner bottom surface at a position located in front of the guide.
