A recording apparatus, comprising: an apparatus body; a recording device that is provided inside the apparatus body and performs recording on a medium; a supporting tray that is switchable between a drawn-out state and a housed state and, when in the drawn-out state, supports the medium that is to be fed toward the recording device, the drawn-out state being a state of being drawn out from the apparatus body, the housed state being a state of being housed in the apparatus body; and a unit that is detachably attached to the apparatus body and includes a reverse roller for reverse the medium, wherein the supporting tray has a portion that is configured to be on a path of attachment and detachment of the unit when in the housed state.

A medium conveying apparatus includes a housing including an accommodation portion provided with a guide portion at an end portion in a width direction, a tray accommodated in the accommodation portion so as to be pulled out, and including a placing surface for placing an ejected medium, and an engaging portion provided on a side surface of the tray, to engage the guide portion. The guide portion includes a pair of rails inclined upward and having a predetermined width. The engaging portion includes two protrusions provided so as to slide between the pair of rails and located apart from each other by a predetermined distance. By locating the two protrusions between the pair of rails, the tray is positioned at a predetermined position with respect to the housing with a front end portion of a downstream side in the medium ejecting direction located upward.

An image forming apparatus is provided that forms an image on a sheet material based on a sheet material setting relating to the sheet material. The image forming apparatus includes an accepting unit configured to accept a selection of a sheet material type, a thickness measurement unit configured to measure a thickness of the sheet material, and a setting determination unit configured to determine the sheet material setting that relates to the thickness of the sheet material based on the sheet material type accepted by the accepting unit and the thickness of the sheet material measured by the thickness measurement unit.

In an image forming system, a hardware processor controls whether the first sheet is conveyed to an upstream side of the image former via a first conveying path which reverses sides of the first sheet or via a second conveying path which does not reverse the sides of the first sheet as well as the first conveying path, when images are formed on both sides of a plurality of the first sheets by the image former, in order to narrow a space between a plurality of the first sheets.

This image forming apparatus (100) is equipped with: a document set detector (3a, S1, S5); a document size detector (3a, S2, S3, S5); a manual feeder (6) with a manual feed tray (61) that is not equipped with a sensor for detecting the size of set manually-fed paper; a printer (5) that performs printing on the basis of image data; an operation panel (4) that receives setting for feeding paper from the manual feeder (6); and a controller (7) that recognizes the size of a set document and performs manually-fed-paper automatic setting for recognizing the recognized size of the set document as the size of the manually-fed paper.

A sheet feeder includes a manual feeding tray to stack a sheet, the tray being openable and closable to a main body by rotation about a rotation axis in a direction perpendicular to a sheet feeding direction; a sheet width regulating member provided in the manual feeding tray to regulate a side edge of the sheet in a sheet width direction and to have a variable regulating width; an auxiliary tray that does not move with an opening/closing operation of the manual feeding tray and stacks the sheet with the manual feeding tray; a sheet width regulating member provided in the auxiliary tray to regulate the side edge of the sheet and to have a variable regulating width; a link member interlocking the regulating members; and a feeding roller provided in the main body to individually feed the sheet stacked over the manual feeding tray and the auxiliary tray.

Disclosed is a sheet feeding apparatus including: a tray unit provided rotatably with respect to an apparatus main body; a sheet stacking member which can be moved to a stand-by position for waiting for sheet feeding and a feeding position at which a sheet can be fed; a moving portion which abuts against the sheet stacking member from below and to move the sheet stacking member to the feeding position and the stand-by position, the moving portion being movable to a first position at which the moving portion locates the sheet stacking member at the stand-by position and to a second position at which the moving portion locates the sheet stacking member at the feeding position; and a restricting portion which restricts movement of the sheet stacking member by interfering with the moving portion located at the first position when the sheet stacking member moves.

An image forming device includes a device body; a conveyance table that is inserted into and pulled out of the device body and that forms a conveyance path for a sheet; a sheet mount tray; a paper feeder that feeds the sheet from the sheet mount tray to the conveyance path; and a movable support that movably supports the paper feeder on the conveyance table in a state where the conveyance table is pulled out of the device body. The paper feeder covers a predetermined part of the conveyance path in a state where the paper feeder disposed on the conveyance table is inserted into the device body, the sheet mount tray is disposed in the device body and separates from the paper feeder when the conveyance table is pulled out of the device body, and the paper feeder moves away from the predetermined part.

A manual sheet feeding device includes: a sheet feeding rotary body configured to separate and feed recording media placed on a manual sheet feeding unit one by one; a shielding unit configured to cover an outer side surface of the sheet feeding rotary body, the shielding unit having an aperture for exposing at least a part of the sheet feeding rotary body to an outside; and an opening and closing unit configured to open and close the aperture of the shielding unit.

An image forming apparatus includes an image forming unit, a paper loading base on which manual-feed paper is loaded, a manual-feed paper conveying unit, and a dustproof cover which covers the paper loading base being in the overhang state. The paper loading base has a lower end rotatably supported on one outer surface portion of the device main body, and is opened from an upper end thereof and disposed at a predetermined oblique angle or in a horizontal overhang state such that an overhang side becomes an upper side in an oblique direction. The manual-feed paper conveying unit is conveys the manual-feed paper on the paper loading base onto a paper conveyance path one by one. The dustproof cover includes a base which engages with the paper loading base, and an opening-and-closing cover which is rotatably connected to the base and is opened upwardly on the overhang side.
