Patent ID: 8587845

Claim:
An image reading apparatus, comprising: a lower unit; an upper unit arranged above the lower unit and rotatably supported by the lower unit; and a guide arranged on an opposite side to the lower unit with respect to the upper unit and rotatably supported to be coaxial with the upper unit so that the guide and the upper unit are rotatable around a common axis, wherein the guide is relatively rotatable with respect to the upper unit in a direction away from the upper unit so as to form an ejection path, between the upper unit and the guide, for a sheet medium conveyed between the upper unit and the lower unit, the upper unit and the guide are in proximity to each other at positions closest to the lower unit in respective rotation ranges of relative rotation with respect to the lower unit, and the rotation range of the guide is wider than that of the upper unit, in a rotation direction away from the lower unit from the positions close to each other.
