A paper aligning mechanism and an image generating device having the same are provided, the paper aligning mechanism is arranged on a calibration path of the image generating device, the calibration path is arranged between a paper assigning mechanism and a paper-feeding mechanism of the image generating device, and the paper aligning mechanism has at least two calibrating swingarms arranged spacedly. Each of the calibrating swingarms has an arm portion and a pivoting axle portion arranged on the arm portion to pivotally connect the arm portion to the image generating device. The arm portion has an extending segment and a limiting segment extended from the extending segment, the limiting segment is downward extended along the calibration path toward an exit of the calibration path to be swingable and to block the exit of the calibration path.

A medium conveying apparatus includes an imaging device to image a medium and configured to move in a moving direction, a roller configured to move in the moving direction, on an upstream side of the imaging device, a conveyance guide provided with the imaging device to move the imaging device, wherein the conveyance guide includes a slope for coming into contact with the medium, an engaging member provided with the imaging device to move the imaging device, and a moving member to move the imaging device by engaging with the engaging member in conjunction with a movement of the roller. The engaging member and the moving member are configured to be separated at a distance from one another when the medium is not conveyed. The moving member moves the imaging device by engaging with the engaging member only when the medium has a thickness greater than the distance.

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.

In one example, a media flag is disclosed. The media flag can rotate between a first position and a second position. The media flag translates parallel with the axis of rotation as the media flag rotates from the first position to the second position.

According to one embodiment, a sheet conveying device includes a placement tray, a presence detection sensor, and a control unit. The placement tray places a sheet thereon. The presence detection sensor detects the presence or absence of the sheet on the placement tray. The control unit delays a determination timing of the presence or absence of the sheet placed on the placement tray to a predetermined timing when a condition indicating that the remaining sheets placed on the placement tray are only a few is satisfied.

An image forming apparatus including an image forming unit, a discharging portion, a supporting portion, an image reading portion, and a switching portion is provided. The image forming unit is configured to form an image on a sheet. The discharging portion is configured to discharge the sheet on which the image has been formed. The supporting portion is configured to support the sheet discharged by the discharging portion. The image reading portion is configured to read, at a reading position, the image formed on the sheet. The switching portion is configured to switch between causing the sheet discharged by the discharging portion to be conveyed to the supporting portion and causing the sheet discharged by the discharging portion to be conveyed toward the image reading portion. The sheet conveyed toward the image reading portion is conveyed to the reading position after conveyance by the discharging portion is finished.

An image forming apparatus including an image forming unit, first and second discharging portions, first and second supporting portions, an image reading portion, and first and second switching portions is provided. The first switching portion switches between causing a sheet bearing an image formed by the image forming unit to be discharged to the first supporting portion by the first discharging portion and causing the sheet to be conveyed toward the image reading portion that reads the image. The second switching portion switches between causing the sheet whose image has been read to be conveyed toward the second discharging portion that discharges the sheet whose image has been read to the second supporting portion and causing the sheet to be conveyed toward the image forming unit. The image reading portion is disposed above the first discharging portion and further on the inside of the apparatus than the second switching portion.

A discharge unit discharges the sheet has an image. A switching unit switches between stacking the sheet discharged from the discharge unit on a stacking unit or conveying the sheet the discharge unit toward an image reading apparatus. A conveyance unit conveys the sheet conveyed via the switching unit to a reading unit. A cooling unit cools the sheet discharged from the discharge unit or cools the reading unit.

A sheet feeder includes a sheet platen, a pickup roller, a feeding roller, a regulating portion, a driving mechanism, a feeding control unit, a sheet sensor, and a determination processing unit. The feeding control unit executes a feeding operation by rotationally driving the pickup roller and the feeding roller in a state where the regulating portion is located at a retreating position. The sheet sensor is located at a downstream side in the feeding direction of the feeding roller. The determination processing unit determines whether the sheet feeding has succeeded or not based on a signal from the sheet sensor. After a start of the feeding operation, when the determination processing unit determines that the sheet feeding has failed, the feeding control unit once moves the regulating portion located at the retreating position to the abutting position and then executes the feeding operation again.

A medium transport apparatus includes: a medium mounting section configured to mount a medium; a feed roller configured to feed the medium from the medium mounting section; a separation roller configured to nip and separate the medium from the feed roller; a plurality of sensors disposed at positions facing a surface of the medium and configured to detect movement of the medium; and a control unit configured to stop feeding of the medium based on detection values received from the sensors, wherein the plurality of sensors are disposed upstream of a nipping position by the feed roller and the separation roller with a gap in a width direction being a direction intersecting a medium feed direction and detect movement of the medium in the width direction.
