Abstract: The present invention intends to provide a printing apparatus that can lessen a reduction in ejection performance caused by thickening, solidification, or the like of print liquid in an ejection port of a printing unit even in the case of stopping a print operation by the printing unit to perform a post-process on a print medium. The printing apparatus includes a post-processing part configured to, in a state of stopping the print operation by the printing unit, perform the post-process on a printed print medium as well as including an open/close unit configured to selectively perform a closing operation or an opening operation of the ejection port provided in the printing unit. Further, when the print medium is stopped in the post-processing part, the open/close unit is controlled so as to bring the ejection port into a close state.

Abstract: Provided is a structure capable of preventing shaking of an image reading unit (1) during movement at low cost. A first contact portion (T1) between the image reading unit (1) and a guide shaft (2A) supports force (F1) acting in a gravity direction and force (F2) acting in a horizontal direction in the case where the image reading unit (1) moves in a predetermined direction. In this case, the first contact portion is arranged so as to satisfy F1>F2×tan θ1, where θ1 represents an angle formed by a perpendicular line (γ) with respect to a tangential plane (β) of the guide shaft (2A) and the horizontal direction. Thus, the image reading unit (1) can be prevented from being lifted due to rotation moment during movement.
