A medium-discharging device includes: a device main body including a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; and a pressing member that is configured to be attached to and detached from to the device main body and presses the medium discharged by the medium-discharging section against the medium-receiving tray in a state in which the pressing member is attached to the device main body, in which the pressing member is configured to switch, in the state in which the pressing member is attached to the device main body, between a first state in which the pressing member comes into contact with the medium-receiving tray and a second state in which the pressing member retreats upward so as to be apart from the medium-receiving tray.

A correction structure arranged in a feeding path of a document processing device, comprising: a transmitting means consisted of at least a pair of roller sets which are arranged symmetrically on the two sides of the feeding path for transmitting the card evenly, a correcting means consisted of a platform movably arranged at the downstream to the roller set, a receptacle formed on the platform, an elastic object arranged in the receptacle for returning the platform to a predefined location, a back wall extended from the platform toward the feeding path, an opening formed on the back wall to let a card go through, and a friction pad arranged at the bottom of the opening to partly jam the opening, wherein the width of the friction pad is less than the width of the feeding path so the friction pad only contacts the center of the card while transmitting the card.

A loading unit includes a processing tray, alignment units, and a paddle. In the processing tray, a medium is placed. The alignment units are disposed an interval in a Y direction to align a downstream tip end in a positive A direction of the medium. The paddle moves the medium that has been fed onto the processing tray toward the alignment units. A coefficient of friction of a contact surface of the alignment unit is higher than a coefficient of friction of a front face of the alignment unit, and the contact surface is positioned downstream of the front face in the positive A direction.

A singling apparatus and a system for singling sheet material comprises a sheet store for receiving a sheet stack of sheets to be singled. The sheet store includes a singling gap, which is formed and arranged to deliver a sheet out of the sheet store to a transport mechanism. The singling apparatus comprises further a singling device comprising a rotating separation roller wherein the separation roller comprises partially on its rotational surface a contact area to periodically contact and transport the sheet from the sheet store to the transport mechanism. A position control device of the singling apparatus is coupled to the separation roller and comprises an alignment indication being in correlation with an angle position of the contact area of the separation roller and indicates the alignment of the contact area to the singling gap and/or the sheet.

A sheet aligning mechanism includes first and second aligning rollers that form a nip therebetween, to which a leading end of a sheet to be aligned is conveyed. The first aligning roller includes first and second roller portions along a rotational axis of the first aligning roller, the first roller portion including a center of the first aligning roller in an axial direction, and a friction coefficient of a surface of the second roller portion is lower than a friction coefficient of a surface of the first roller portion.

A sheet aligning mechanism includes first and second conveyance mechanisms disposed on first and second sides of a sheet conveyance path, respectively. A nip is formed between the first and second conveyance mechanisms. The first conveyance mechanism includes a first roller, a second roller, and a first conveyance belt wound around the first and second rollers. The first and second rollers are configured to rotate in a first direction along a sheet conveying direction for sheet conveyance, and stop rotation or rotate in a second direction opposite to the first direction for sheet alignment. The first conveyance belt includes an extended region between the first and second rollers in an extending direction inclined with respect to the sheet conveying direction, such that a width of the sheet conveyance path becomes narrower towards the nip in the sheet conveying direction.

A medium discharging apparatus includes a first tray in which a medium is received and placed, a second tray in which a medium discharged from the first tray is received, a discharging mechanism that discharges the medium from the first tray toward the second tray, and a first curl suppressing member that is located above a rear end region of the medium in the discharge direction and that moves so as to follow movement of the rear end region while maintaining an attitude of the medium until the medium placed on the first tray is discharged from the first tray to the second tray by the discharging mechanism and placed on the second tray.

Provided is a sheet processing apparatus, including: a regulation portion configured to contact with an end edge of a sheet to be conveyed and to regulate a position of the sheet; a position adjustment portion configured to perform position adjustment on a sheet in a direction along an end edge of the sheet of which the end edge is in contact with the regulation portion; a folding portion configured to perform folding processing on a sheet which has been regulated by the regulation portion; and a control portion configured to execute: a first mode of causing the folding portion to perform the folding processing on a sheet which has been regulated by the regulation portion, without causing the position adjustment portion to perform the position adjustment on the sheet; and a second mode of causing the position adjustment portion to perform the position adjustment with respect to the regulated sheet.

A medium conveyance device includes a medium setting part on which a medium is set, a first roller coming in contact with the medium set on the medium setting part and sending out the medium in a conveyance direction, a second roller situated on a downstream side of the first roller in the conveyance direction and conveying the medium sent out by the first roller, and a medium contact part arranged in a conveyance path between the first roller and the second roller and coming in contact with the medium. The medium contact part has a plurality of contact surfaces switchable according to a type of the medium and differing in shape.
