A sheet feeder includes a tray configured to load a sheet to be fed thereon. The tray has a tray upper face and a pair of cursors. The tray upper face has a recessed portion, a guide plate and a feeding route. The recessed portion extends along the width direction on an upstream side from the pair of cursors in the feeding direction. The guide plate is configured to cover an upper side of the recessed portion. The feeding route is formed between the recessed portion and the guide plate and extending from an inlet port positioned on an upstream side to an outlet port positioned on a downstream side along the feeding direction. The sheet in a state of being passed through the feeding route is aligned with the pair of cursors on the tray upper face and then fed.

A box machine is retrofitted by removing the upper feed roll, sheet feeder, and by replacing the lower feed roll with a drive shaft. A transport section and a sheet feeder are then inserted into the box machine. The transport section comprises transport wheels driven by the drive shaft which engage a sheet to transport it to the box machine without crushing. The sheet feeder comprises feed wheels driven by a servo motor for feeding the lowermost sheet of a stack to the transport section. A feed interrupter is movable from a raised stop-feed position to a lowered feed position by cams rotated by a servo motor. A controller coordinates the velocity of the feed wheels and position of the feed interrupter. Retrofitted machines eliminate the need to increase Edge Crush Test ratings of sheets from the corrugator 15% to 20% greater than printed in the certificate stamp.

An automatic teller machine includes a guide, shafts and rollers. The guide extends in a conveyance direction along which papers are conveyed and includes a conveyance surface on which the papers are conveyed. The shafts are retained in the guide, and the rollers are turnably supported by the shafts. The guide includes a roller slot in which the rollers are disposed, and pairs of shaft slots that are opposingly formed to sandwich the roller slot. Each pair of shaft slots retains two ends of one of the shafts. The guide may include protrusion portions in the shaft slots that protrude in a direction orthogonal to the conveyance surface, and the shafts may include holes through which the protrusion portions are inserted when the shafts are retained in the shaft slots. Projection portions may be formed at the guide, projecting from predetermined positions of inner faces of the shaft slots, and the projection portions may abut against the shafts when the shafts are retained in the shaft slots.

An image forming device includes a sheet container, an image former that forms an image on a surface of a sheet conveyed from the sheet container, and a re-conveyor that re-conveys the sheet to the image former which forms another image on an opposite surface of the sheet. The re-conveyor includes a first conveyance roller set and a second conveyance roller set that convey the sheet therebetween. The first conveyance roller set includes a first driving roller that receives a driving force and a first pinch roller that contacts the surface. The second conveyance roller set includes a second driving roller that receives the driving force and a second pinch roller that contacts the surface. The first driving roller has a greater coefficient of friction than the first pinch roller. The second pinch roller has a greater coefficient of friction than the first pinch roller.

An image forming apparatus includes an image forming device and a sheet adjusting device to adjust a lateral position of the sheet by moving a sheet in a lateral direction perpendicular to a sheet conveyance direction. The sheet adjusting device moves a driving roller in one of a first direction and a second direction for adjusting a lateral position of the sheet between the driving roller and a driven roller and then adjusting a lateral position of the driven roller to the driving roller by moving the driving roller in the second direction until the misaligned driven roller laterally contacts respective stoppers to restrict a range of lateral movement of the driven roller while the sheet is separated from the driving roller and the driven roller and by further moving the driving roller to a predetermined position while the driven roller remains contacting the stoppers.
摘要:
A method and apparatus are disclosed for guiding an item of media travelling along a pre-determined transport pathway. The apparatus includes a guide body comprising an arcuate guide surface, at least one drive roller comprising an outer drive surface, and at least one pulley member having an outer item engaging surface that extends through an opening in the guide surface and is urged against the outer drive surface. The drive roller and pulley member co-operate to lift an item away from the guide surface at an arcuate region of the transport pathway.

An image forming apparatus has a rotary guide including a path for a sheet being conveyed. The guide is rotatable so that an exit of the path faces one of at least two conveyance destinations. A motor rotates the guide, and a detector outputs a detection signal when a predetermined posture of the guide is detected. An instructing section outputs instruction signals to the motor to rotate the guide toward the predetermined posture. A judging section judges whether a detection signal has been received in response to the instruction signal, and a notifying section counts a consecutive occurrence number of a judgment result to the effect that no detection signal was received in response to the instruction signal this time and gives a notification prompting an inspection request of the image forming apparatus when the consecutive occurrence number reaches a set number.

A mailpiece feed device comprising a mailpiece-receiving deck for receiving a stack of mailpieces, conveyor rollers for conveying the mailpieces along a longitudinal referencing wall and towards a separator device designed to separate the mailpieces one-by-one from said stack of mailpieces and to convey them downstream, and, incorporated vertically in said longitudinal referencing wall, at least one friction roller of varying roughness, with its coefficient of friction decreasing from the top to the bottom of said longitudinal referencing wall.
