In one embodiment, an image forming apparatus has an image forming device, a discharge port of a recording medium, a conveying device of the recording medium, and a controller. The controller judges a kind of the recording medium and the discharge port that is a conveying destination of the recording medium. The controller controls a conveying speed of the recording medium to be discharged from the discharge port by the conveying device, in accordance with the kind of the recording medium and the conveying destination of the recording medium which have been judged.

In an example embodiment, there is disclosed herein a picker that is operable to separate an individual sheet from a stack of sheets. The picker has a first rotatable picker member that includes a first high friction peripheral arcuate segment, where the first picker member is rotatable about an axis, a second rotatable member that includes a second high friction peripheral arcuate segment, wherein the second picker member is rotatable about the axis, and a drive in operative connection with the first and second rotatable picker members. The stack includes a bounding sheet having a sheet face bounding a side of the stack. The first and second arcuate segments are operable to concurrently engage the sheet face. The first and second picker members are operable to be separately rotationally movable about the axis responsive to operation of the drive.

A rewinding machine is described with a winding cradle defined by three rollers and including a fourth winding roller defining with the first winding roller a cradle in which the web material is pushed by a winding core to the beginning of each winding cycle, to cause severing of the web material without the need for controlled mechanical parts.

A sheet conveying device includes upstream side rollers; discharge rollers located downstream from the upstream side rollers in the feeding direction of sheets, to discharge sheets to a discharge tray; a reflective optical detector located between the discharging rollers and the upstream side rollers, to emit light and to receive light reflected off of the sheets; and a recognizing unit to detect, based on output of the detector, whether or not a sheet is present at a detection region of the detector. When a sheet is fed over a conveying path inclined with respect to a detection face of the detector, the discharge rollers feed the sheet in a bent state between the upstream side rollers and the discharge rollers, so that the sheet is close to the detector or the sheet is close to being perpendicular to an optical axis of the detector.

A resilient unit is fed as a continuous web 18 through first and second tensioning rollers 20, 22 to a winding roller 24. The winding roller is driven at a first speed, and one or both of the tensioning rollers is also driven, but at a second speed which is less than the first speed—i.e. slower than that of the winding roller. The difference is speeds causes tension to be applied to the material of the resilient unit which stretches the resilient unit and in turn compresses the resilient elements in their pockets. The result is that the resilient unit becomes compressed in its through thickness direction—the axial direction of the springs—before it is wound into the winding roller. The resilient unit extends in length in a longitudinal direction in which tension is applied. The extension in length is substantially proportional to a reduction in a thickness of the resilient unit.

A sheet conveying apparatus forms a loop of a sheet between a first conveyance roller pair and a second conveyance roller pair, and before a leading edge of the sheet reaches a nip portion of a third conveyance roller pair, separates the first conveyance roller pair.

A device for the generation of a shingled stream of flat, flexible objects along a conveyor path, wherein successive objects develop an overlap with a length, includes a first and a second suction and conveyor device having a first and second unit, respectively, and each having at least one conveyor belt. The first and second units are each configured to generate a vacuum through a whirlwind to attract at least one of the objects and are each disposed in a casing having a suction aperture. The second suction and conveyor device is disposed downstream from the first suction and conveyor device in a direction of the conveyor path with a mutual offset corresponding to the length of the overlap and is disposed at an angle relative to the direction of the conveyor path. The first and second suction are separated by a spacing in a transversal direction.

A reversely-rotatable roller conveys a sheet having an image formed on its one side at a sheet conveying velocity faster than that of a conveying roller by normal rotation and then, the reversely-rotatable roller conveys the sheet to a re-conveying path by reverse rotation. The sheet conveying velocity of the reversely-rotatable roller when the reversely-rotatable roller reversely rotates is made slower than the sheet conveying velocity when the reversely-rotatable roller normally rotates so that the sheet conveying velocity of the re-conveying roller is substantially equal to or slower than the sheet conveying velocity of the conveying roller.
