A sheet conveying device includes a first roller, a second roller, and a controller. The first roller is configured to rotate in a forward direction for sheet conveyance along a sheet conveying direction. The second roller is disposed downstream with respect to the first roller in the sheet conveying direction and configured to rotate in a forward direction along the sheet conveying direction and in a reverse direction. The controller is configured to control the second roller to rotate in the reverse direction at a timing when a leading end of a sheet that is nipped and conveyed by the first roller reaches a nip of the second roller.

A first roller pair disposed upstream of a second roller pair is separated from each other by a separating mechanism. A control portion is configured to start rotating the second roller pair after a leading edge of a sheet in a sheet conveyance direction is abutted against the second roller pair in a stopped condition. The control portion is configured to execute, based on the information concerning the sheet length acquired by the acquisition portion, either one of a plurality of modes including a first mode of rotating an upstream roller pair and the first roller pair to convey the sheet while the first roller pair is in a contact condition and a second mode of operating the separating mechanism to separate the first roller pair and of rotating the upstream roller pair to convey the sheet while the first roller pair is in a separated condition.

A sheet conveying device includes a corrector configured to correct a position of a sheet, and at least three detectors disposed in a sheet conveyance direction. Each of the at least three detectors is configured to detect a lateral end of the sheet according to a length of the sheet to be conveyed in the sheet conveyance direction. The corrector is configured to correct the position of the sheet based on detection results of each of the at least three detectors.

In some examples, the disclosure describes a device that includes a first media tray positioned at a media input of a pick and separation mechanism, a second media tray positioned at the media input of the pick and separation mechanism, a media scan guide to position a sheet of print media at the media input of the pick and separation mechanism, a shared media path comprising a turn roller to receive the sheet of print media from the pick and separation mechanism from a first direction and provide the sheet of print media to a print zone in a second direction, and an output zone to receive the sheet of print media from the shared media path.

A medium conveying apparatus conveyable a passport includes a guide pair including a first guide, and a second guide located so as to sandwich a medium conveyance path together with the first guide, to regulate a vertical direction of the medium conveyance path, a light emitting element located on an outside of the medium conveyance path with one of the first guide or the second guide in between to detect the medium, a light receiving element located on an outside of the medium conveyance path with the first guide in between, to receive a light emitted by the light emitting element, and an opening provided in the first guide, to pass the light emitted from the light emitting element. A reflectivity in a periphery of the opening of the first guide is 55% or less.

A printing device is provided comprising a camera to capture an image of at least a portion of a print substrate; a controller to determine a location of a portion of a side edge of the print substrate from the image to determine a distance of the print substrate from a predetermined location; and an adjustment apparatus to adjust the entire substrate laterally, relative to the direction of transport of the print substrate, based on the determined location.

An image forming apparatus is provided. The image forming apparatus includes a print engine to form an image on a sheet, a feeding apparatus to pick up a sheet loaded onto a knock-up plate and feed the picked-up sheet to the print engine by using a pick-up roller, a feed roller, and a registration roller, and a processor to, based on a print data being received, control the print engine and the feeding apparatus and allow the received print data to be printed. The processor may variably control a feeding speed of the feed roller and allow the picked-up sheet is conveyed to the registration roller within a predetermined time.

A medium transporting apparatus includes a transport belt that has a loop shaped, a cling mechanism that causes the medium to cling to the transport belt, a rotation mechanism that transports the medium by rotating the transport belt, a plurality of detection units that detect an transport direction end of the medium, a controller that corrects a skew of the medium, and a stacker on which the medium transported by the transport belt is stacked, in which the plurality of detection units are arranged at positions that are on an upstream side of the transport belt in the first transport direction and that are different from each other in a width direction, and the controller corrects, according to a result of the detection by the detection units, the skew of the medium in a state of being cling to the transport belt.

An apparatus for aligning at least one note of value along a transport path including at least one transport element, at least one first drive unit, first and second rotatably mounted deflecting elements, and a second drive unit. The transport element includes an endless drive belt. The first drive unit drives the transport element in a first direction of rotation which moves the note of value along the transport path in a transport direction. The transport element is deflected over the deflecting elements. The second drive unit displaces at least one of the first and second deflecting elements along its axis of rotation so that by displacing the one of the first and second deflecting elements the note of value contacting the at least one transport element is moved obliquely to the transport direction.

A document conveying device includes a document tray, a first rotary member, a first motor, a second rotary member, a second motor, a document feed sensor, and a controller. The controller counts a counted time from the time point that the first motor starts to rotate until the leading end of a document reaches the document feed sensor. When the time resulting from subtracting the counted time from a required sheet-to-sheet time interval is longer than the required speed change time, the controller performs deceleration and post-deceleration acceleration for the first motor. The required speed change time is the time required for speed change from the first rotation speed to the second rotation speed.
