The present disclosure provides an apparatus to support a sheet and configured to stably detect a presence of the sheet with a simple arrangement, and an image forming apparatus including such apparatus. A sheet discharging apparatus includes an apparatus body, a discharge member provided in the apparatus body and configured to discharge a sheet, a movable tray movable with respect to the apparatus body and including a sheet supporting surface configured to support the sheet discharged by the discharge member, a movable member supported by the movable tray and configured to move by being pressed by the sheet supported on the sheet supporting surface, and a detecting portion provided in the apparatus body and configured to detect a presence of the sheet supported on the sheet supporting surface in response to a position of the movable member.

An image forming apparatus including a main body control apparatus, a main body cassette, and an additional cassette different from the main body cassette and coupled to a bus-shaped communication line to which the main body control apparatus is coupled, and the main body control apparatus transmits in image formation an acknowledgement unnecessary command indicating that an acknowledgement is unnecessary to the additional cassette in accordance with the state of the image forming apparatus relating to the additional cassette.

A document conveying device according to the present disclosure includes a sheet feeding tray, a discharge tray, a feeding roller, a first lifting mechanism, a conveying mechanism, a support member and a second mechanism. On the sheet feeding tray, a document is stacked. The discharge tray is provided below the sheet feeding tray. The feeding roller feeds the document on the sheet feeding tray. The first lifting mechanism supports both end portions of the sheet feeding tray in a width direction intersecting a conveying direction of the document, and lifts and lowers the sheet feeding tray such that an upper surface of the document comes in contact with the feeding roller. The support member supports the sheet feeding feed tray on an upstream side of the first lifting mechanism in the conveying direction. The second lifting mechanism lifts and lowers the support member in synchronization with the sheet feeding tray.

A medium feeding device includes: a medium mounting section onto which a medium to be fed is mounted; a feeding unit that feeds the medium mounted on the medium mounting section; and a supporting member that supports an end in a width direction of the medium mounted on the medium mounting section and that supports the medium at a higher position than the medium mounting section in a direction of loading of the medium, the width direction being a direction crossing a feed direction.

A feeding device includes an accommodating unit, a feeding member, a regulating member, a member-to-be-detected, a detecting device, and a connecting member. The regulating member contacts the member-to-be-detected in a first region with respect to a feeding direction and is spaced from the member-to-be-detected through the connecting member in a second region different from the first region with respect to the feeding direction.

According to one embodiment, a sheet conveying device includes a tray and a correcting member. On the tray, a sheet bundle in which a plurality of sheets are overlapped is stacked in a thickness direction of the sheet bundle. The correcting member moves relative to the tray in the thickness direction. The correcting member abuts against an upper layer portion of an outer peripheral portion of the sheet bundle on the tray, and presses the upper layer portion from an outside after abutting. The correcting member corrects a position of the upper layer portion in a lateral direction intersecting the thickness direction toward an inside from the outside of the sheet bundle.
