Abstract
Provided is a structure capable of preventing shaking of an image reading unit () during movement at low cost. A first contact portion (T) between the image reading unit () and a guide shaft (A) supports force (F) acting in a gravity direction and force (F) acting in a horizontal direction in the case where the image reading unit () moves in a predetermined direction. In this case, the first contact portion is arranged so as to satisfy F>F×tan θ, where θrepresents an angle formed by a perpendicular line (γ) with respect to a tangential plane (β) of the guide shaft (A) and the horizontal direction. Thus, the image reading unit () can be prevented from being lifted due to rotation moment during movement.
