A sheet material feeding apparatus includes: a cassette configured to internally contain a sheet material; a push-up plate that is mounted on an inner bottom surface of the cassette and that is a plate on top surface of which the sheet material is mounted; a push-up plate displacement mechanism configured to include push-up plate biasing members and to change a posture of the push-up plate using a biasing force of one of the push-up plate biasing members; a width regulating member configured to be displaced in a width direction intersecting with a feeding direction and to regulate a position of the sheet material; and a biasing member selecting mechanism that includes a switching unit configured to switch application and release-application of the biasing force of one of the push-up plate biasing members to a posture change of the push-up plate, in interlocking with displacement of the width regulating member.

An apparatus is provided that may offer functionalities including printing, scanning and/or copying. The apparatus may include a manual sheet feeding tray disposed at the rear of the apparatus. The height of the sheet feeding tray might not exceed a height of the apparatus, allowing use of the apparatus in spaces having smaller depths. The apparatus may include a sheet guide configured to move in conjunction with the movement of the tray. In some arrangements, a surface of the sheet feeding tray may differ in height between lateral edges of the tray and a central portion. This difference may cause a sheet to be curved in a lateral direction, rendering the sheet more inflexible in a longitudinal direction. According to other aspects, a depressed portion of the tray may match a protrusion extending from the guide in shape such that the two portions may mate in a retracted position.

An image forming apparatus performs skew correction by bringing a leading end of a conveyed sheet in contact with a registration roller pair being in a stopped state and by forming a first loop with a loop roller pair, and thereafter, refeeds the sheet to an image former by adjusting timing. In a case of feeding a sheet with a length equal to or longer than a prescribed length, after having formed the first loop, the image forming apparatus forms a second loop in a loop accommodator that is disposed on an upstream side than the loop roller pair and accommodates a formed loop.

An image reading apparatus includes a stacking portion, a feeding unit, a reading unit, and a discharge portion provided below the stacking portion. The feeding unit feeds a sheet stacked on the stacking portion in a feeding direction. The reading unit reads an image on the fed sheet and the discharge portion discharges the read sheet. The stacking portion includes first and second support surfaces that support the sheet and first and second regulating units to regulate a position of the sheet in a widthwise direction using two opposing ends of the sheet. The second support surface is retractable from a predetermined section above the discharge portion. The first support surface includes a downstream support portion that supports the sheet on a downstream side of the predetermined section in the feeding direction. A part of the second regulating surface is positioned on the downstream support portion.

A medium processing apparatus for processing a medium ejected from an image forming apparatus includes a conveyor, a slit, a medium processing device, a stopper, and detectors. The conveyor conveys the medium ejected from the image forming apparatus. The slit communicates with an opening of a housing into which a medium is manually inserted from outside and includes a placement face on which the inserted medium is placed. The placement face has a first side and a second side orthogonal to the first side. The first and second sides are not parallel to a direction in which a side face of the housing extends. The medium processing device processes the medium conveyed by the conveyor or the medium placed on the slit. The stopper regulates edges of the medium along the first and second sides of the placement face. The detectors are disposed on the stopper to detect the medium.
