Abstract: An object of the present invention is to provide a printing apparatus including a scanner unit openable and closable with respect to a printer body unit for simultaneously achieving smooth opening/closing movement and the downsizing of the apparatus. The printing apparatus includes a first gear member provided in the printer body unit and a second gear member which is attached to the scanner unit so as to be swingable with respect to the scanner unit and which is in mesh with the first gear member. When the scanner unit opens or closes with respect to the printer body unit, the second gear member swings with respect to the scanner unit while retaining a meshing state with the first gear member.

Abstract: An image reading apparatus is provided with a reader which reads a document, a transport roller which is provided on an upstream side of the reader in a document transport path in which the document is transported and transports the document to a reading position of the reader, and a controller which receives reading data of the reader and controls the transport roller, in which the controller receives the reading data from the reader to acquire a form of the document, and selects whether or not to stop driving of the transport roller based on the form.
