In a sheet stacking device, a first sheet storage portion and a second sheet storage portion are arranged in alignment in a width direction of a housing, and supported by the housing so as to move in a front-rear direction perpendicular to the width direction. Biasing members are respectively provided on opposite side surfaces of the first and second sheet storage portions, the opposite side surfaces being adjacent and face each other in the width direction. In a first state where the first and second sheet storage portions are moved frontward from the housing, the biasing members abut on each other and bias the first and second sheet storage portions in directions in which the first and second sheet storage portions separate from each other along the width direction.

A medium feed apparatus includes a first support face and a second support face. The first support face supports a medium fed by a feed unit that feeds medium by supporting such that the medium adopts an inclined orientation. The second support section is positioned upstream of the first support face in a feed direction, and supports the medium together with the first support face. The second support face is at a position set back from the first support face, and an angle of inclination from a lower end portion to an upper end portion of the second support face is steeper than an angle of inclination of the first support face.

A sheet feeding apparatus includes: a transfer medium loading tray that is movable vertically; a hardware processor configured to control vertical movement of the transfer medium loading tray; an overload detector configured to detect transfer media of a maximum loading amount prescribed for each type of the transfer media; and an intermediate tray position detector configured to detect the transfer medium loading tray being at an intermediate tray position prescribed for each type of the transfer media, wherein the hardware processor is configured to control the vertical movement of the transfer medium loading tray in accordance with a type of the transfer media and on a basis of a vertical position of the transfer medium loading tray, results of detection by the overload detector, and results of detection by the intermediate tray position detector.

A paper feed device of the present disclosure is provided with a first cassette and a second cassette, a casing, and a support member. The first cassette and the second cassette are arranged side by side in a cassette width direction. The casing has a cassette housing portion. The support member is capable of supporting the first cassette and the second cassette. Each of the first cassette and the second cassette is provided with a pressing portion. In a state where the first cassette and the second cassette are housed, the support member is disposed at a first position retracted upward, while in a state where at least one of the first cassette and the second cassette is pulled out, the support member is pressed downward by the pressing portion so as to be disposed at a second position where the support member is contactable with an installation surface.

A sheet feeding apparatus includes a supporting portion and a feeding unit. The supporting portion supports a sheet and is capable of being drawn out from and being attached to an apparatus body. The feeding unit is provided in the apparatus body and includes a feeding portion, a conveyance portion, a separation unit, and a guide member. The feeding portion feeds the sheet supported by the supporting portion. The conveyance portion conveys the sheet. The separation unit forms a separation nip with the conveyance portion and is detachable from the feeding unit. The guide member includes a guide surface and a lower surface. The guide surface guides the sheet to the separation nip. The lower surface is provided below the guide surface and includes an exposing portion exposing at least a part of the separation unit.

An image production device includes a processor, media feed trays having media size sensors, and a marking device. A scanner connected to the processor, scans images on a two-dimensional document and determines one dimension of the document. The processor automatically determines dimensions of media in the media feed trays and compares the dimensions of media in each of the media feed trays to the one dimension of the document. Responsive to the one dimension of the document matching one of the dimensions of the media in one of the media feed trays, the processor identifies a matching feed tray based only on one dimension of the document in the scanner. Media is automatically selected from the matching feed tray and fed to the marking device. The marking device renders images on the media selected from the matching feed tray. The processor outputs the media containing the images.
