An example bridge module includes a media transport roller to move in a translational direction, a rotatable guide proximate to the media transport roller, a handle coupled to the rotatable guide to cause the rotatable guide to articulate into an open configuration and away from the media transport roller, and an elongated member operatively connected to the rotatable guide, the elongated member to articulate into the open configuration creating an unobstructed pathway to the media transport 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.

There is provided a sheet conveyance device that includes a first conveyance roller and a second conveyance roller that are arranged at a position other than a center in a direction of sheet width in a sheet conveyance path, a roller selector that selects the first conveyance roller or the second conveyance roller as a roller to convey a sheet, and a controller that causes the roller selector to select the first conveyance roller or the second conveyance roller. The first conveyance roller is made of a material that causes a speed of the sheet conveyed by the first conveyance roller in contact with the first conveyance roller to be higher than a rotation speed of the first conveyance roller. The second conveyance roller is made of a material that causes a speed of the sheet conveyed by the second conveyance roller in contact with the second conveyance roller to be lower than a rotation speed of the second conveyance roller.

A printer includes: a conveyor; a printing device; a full-cut unit provided downstream of the printing device; a roller provided downstream of the full-cut unit; a nip member; a motor; and a controller configured to: control the full-cut unit to fully cut the printing medium; control the motor to establish a state in which a leading printing medium is nipped between the roller and the nip member; and control the conveyor to convey a succeeding printing medium downstream while controlling the printing device to perform printing on the succeeding printing medium.

A card processing device may include a print unit and a card inverting unit that inverts front/rear of the card. The print unit may include a thermal head and a card conveyance mechanism. The card inverting unit may include a card holding part, a card drawing and feeding mechanism, and a rotating mechanism that rotates the card holding part. A conveyance path may be provided inside the card holding part. The conveyance path may be linear. The card drawing and feeding mechanism may include two drive rollers, and two pad rollers. A distance between a center of the drive roller and a center of the thermal head may be shorter than a length of the card. The thermal head may print on the card while the card conveyance mechanism conveys the card. The rotating mechanism may rotate the card holding part such that the conveyance path is inclined.

In accordance with an embodiment, an image forming apparatus comprises an image forming section configured to form an image on a sheet; a sheet discharge port through which the sheet is discharged; a sheet conveyance roller configured to convey the sheet to the sheet discharge port; a movable sheet guide, arranged in such a manner that an imaginary line connecting a portion contacting the sheet of the sheet conveyance roller with the sheet discharge port passes through a cross-sectional area, configured to be capable of moving in a direction away from a surface of the sheet; and a guide sensor configured to detect movement of the movable sheet guide.

A sheet discharge device includes a sheet discharge roller pair composed of an upper roller and a lower roller; and a placement tray, arranged below the sheet discharge roller pair, configured to place a sheet discharged from the sheet discharge roller pair. The device further includes a sheet presser configured to be held on a sheet discharge side of the upper roller in a movable manner and pushed up by a sheet front end to be discharged, and depress a sheet rear end with the dead weight thereof after the sheet rear end passes through a nip between the sheet discharge roller pair. The device additionally includes an auxiliary tray that is movable between a first position where the sheet rear end depressed by the sheet presser is caught and a second position where the sheet rear end is released from the sheet presser.

A dual nip release mechanism includes: a rigid actuator body including a tail portion with a handle and a pivotally-mounted head portion having a nose member extending therefrom; a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with a first shaft; and legs hingedly connected to the tail portion, each leg having a foot engaged with a second shaft and a heel for camming engagement with a fixed plate. During use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.

A sheet feeding apparatus, including: a pair of sheet feeding rollers; a pair of conveyance rollers; and a controller, wherein when a first condition regarding a sheet position is fulfilled in the sheet feeding, the controller makes one of the first conveyance roller and the second conveyance roller move in a direction opposite to the other conveyance roller and when a second condition regarding the sheet position is fulfilled in the sheet feeding, the controller makes the one conveyance roller move in a direction toward the other conveyance roller.

In an example, a clamp may include a chassis, a swingarm disposed on the chassis, a clamp wheel disposed on a first end of the swingarm to engage with a drag portion of the chassis, and an auxiliary bias member to exert a force against the clamp wheel to resist a rotation of the clamp wheel. The force may periodically increase in magnitude.
