Relay transport device, recording system, and feeding system

A feeding unit includes a paper feeding tray, a lifter, a feeding roller, a guide plate, and a handling portion. The lifter can displace paper in the paper feeding tray in a +B direction. The guide plate guides a downstream end of the paper lifted by the lifter in a +A direction toward the feeding roller. The handling portion handles the paper toward the feeding roller. The guide plate forms a frontage through which the paper can pass between the guide plate and an outer peripheral surface of the feeding roller, and is provided so that a size of the frontage can be adjusted. The handling portion is provided integrally with the guide plate.

Feeding device and recording device

A feeding unit includes a retard roller, a first holder, a second holder, an accommodating portion, a pressing portion, a second pressing portion, a release lever, and a second restricting portion. The accommodating portion accommodates the second holder. The second pressing portion presses the second holder in a +Z direction. The release lever restricts the movement of the second holder in the +Z direction. The second holder is provided with a plurality of restricted portions in a Y direction and a +A direction, respectively. The second restricting portion restricts the movement of the second holder in a −Z direction. The second restricting portion has a restricting surface. The restricting surface is provided in the accommodating portion and is configured to come into contact with the plurality of restricted portions.

A drive transmission unit includes a cam member, a motor, a cam follower, and an extension spring. The cam member rotates about a rotation shaft. The cam member includes a first cam defining a maximum distance between the cam follower and the rotation shaft and a second cam having an outer peripheral surface positioned closer to the rotation shaft than the outer peripheral surface of the first cam. The motor rotates the rotation shaft. The cam follower is to be in contact with the cam member and moves in the +B direction and the −B direction by the rotation of the cam member. The extension spring presses the cam follower against the cam member. When the cam follower moves in the −B direction by the rotation of the cam member, this operation includes contact between the outer peripheral surface of the second cam and the cam follower.

Drive transmission device, feeding device, and printing apparatus

A feeding unit includes: a retard roller; a holder section; a protruding section; an accommodating section; a pressing section; a first restricting section; and a second restricting section. The holder section rotatably holds the retard roller. The protruding section serves as a rocking fulcrum of the holder section. The accommodating section accommodates the holder section. The pressing section presses the holder section. The first restricting section restricts movement of the holder section in a retreating direction. The second restricting section restricts movement of the holder section in a direction opposite to the retreating direction. The pressing section is arranged so as to deviate in a Y direction with respect to a virtual line passing through a middle point of the protruding section and a middle point of the first restricting section. The holder section comes into contact with the first restricting section and the second restricting section.

Feeding device

A media folding device includes a stacking portion on which media transported from an introduction path are placed; a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion; and a bend forming mechanism that includes a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction, and that causes the folding position of the media to be nipped by the folding roller pair the folding roller pair by shortening the relative distance between the first abutting portion and the second abutting portion to bend the media toward the folding roller pair.

Media folding device and control method for media folding device

A medium discharging device includes a side cursor, a moving unit, a discharge unit, and a side guide. The side cursor is provided in a processing tray and is provided movable in an intersecting direction intersecting a discharging direction of the medium, aligns an end portion of a media bundle in the intersecting direction, and guides the media bundle in the discharging direction when the media bundle is discharged. The moving unit moves the side cursor in the intersecting direction. The discharge unit discharges the media bundle from the processing tray to the discharge tray where the media bundle is placed. When the media bundle is discharged, the side guide is disposed alongside the side cursor in the discharging direction and restricts movement of the media bundle in the intersecting direction, which is discharged by the discharger.

Medium discharging device, post-processing device and recording apparatus

A medium transporting apparatus including a paddle that comes in contact with a medium discharged on a first tray including an upstream end matching member and that rotates to move the medium towards the upstream end matching member, and a low frictional resistance member configured to switch between an advanced state advanced from outside a medium mount region of the first tray to a first region, and a retracted state retracting from the first region to an outside of the medium mount region. The low frictional resistance member is, after a first medium is mounted on the first tray, switched from the retracted state to the advanced state, and is interposed between the first medium and a second medium when, after discharging the first medium, moving the second medium discharged from a pair of discharge rollers towards the upstream end matching member with the paddle.

Medium transporting apparatus, medium processing apparatus, and recording system

A sheet discharging device includes: a pair of medium supporting portions that have support surfaces that support the medium, and support the transported medium by the support surfaces; a stacking portion which is provided vertically below the pair of medium supporting portions and on which the medium dropped from the pair of medium supporting portions is stacked; and a standing wall that aligns the medium by contacting a rear end of the medium in the transport direction supported by the pair of medium supporting portions, and the standing wall includes: a center contacting wall that is provided at a center in the width direction and contacts the rear end of the medium; and recess portions that are provided on both sides of the center contacting wall in the width direction and are recessed in a direction away from the support surfaces.
