Abstract: An image reading apparatus comprises a reading unit including a sensor; a driving unit configured to move the reading unit to read an original placed on a platen; a feed unit configured to feed the original to move and read the original with respect to the reading unit being at rest in a predetermined position; a transfer unit configured to transfer a driving force of the driving unit to the feed unit while the reading unit is at rest in the predetermined position; and a switching unit configured to permit or restrict movement of the reading unit from the predetermined position.

Abstract: An image processing apparatus has an original mount, a recording material mount for mounting recording materials, a supply roller, a separating unit, a reading unit for reading an image of the original, an original detection sensor for detecting the original on the original mount, and an original widthwise direction reference surface for being abutted by the original mounted on the original mount to position that original. The recording material widthwise direction reference surface is used to position the recording material so that a portion of the original does not superpose on the recording material having a maximum width and the original detection sensor detects that a portion of the original mounted on the original mount is not superposed on the recording material having maximum width.

Abstract: There is provided a recording apparatus capable of bringing a delivery tray to an open state automatically when a sheet material is conveyed without the need for a solenoid to open the delivery tray, and preventing the delivery tray from opening inadvertently except during recording.
