Abstract:
A sheet conveyor, which is incorporated in an image forming apparatus, includes a first conveyor to convey a sheet via a first sheet conveying path and move in a direction intersecting a sheet thickness direction, a second conveyor to convey the sheet via a second sheet conveying path and include a third conveyor and a fourth conveyor bringing either one close to and away from the other via the second sheet conveying path in the sheet thickness direction, a first attaching part provided to the first conveyor to attach the first conveyor to the sheet conveyor, and a state changer to change a state of one of the first attaching part to a movement allowed state and the second conveyor to a sheet releasing state in conjunction with a releasing action of the other of the first attaching part and the second conveyor.
Abstract:
A sheet processor includes a processing tray with a first surface that receives sheets and forms a pile of sheets. An endless belt circulates by way of first and second surface sides on a side opposite the first surface of the processing tray. A first roller reverses a circulation path of the endless belt from the first surface side to the second surface side. A second roller is disposed at an interval from the first roller and reverses the circulation path from the second surface side. First and second abutments are attached to the belt and abut an end edge of the pile of sheets. The abutments are attached to the belt so that the first abutment is positioned near the first roller and on the second surface side and the second abutment is near the second roller on the second surface side.
Abstract:
A media transport belt assembly has a continuous belt encompassing two rollers supported on a frame. A tension mechanism biases the rollers apart to generate tension in the belt. The end of one roller moves in response to increased belt tension to skew the first roller with respect to the second roller. The roller end may be pivotally attached to a frame for movement in an arc, or may be otherwise constrained to displace the roller from the plane of the belt.
Abstract:
A feeding device for digital processing machine includes a paper passage, a friction device, and a sheet-feeding module. The sheet-feeding module is disposed in the paper passage and opposite to the friction device. The sheet-feeding module includes a sheet-feeding roller, a first idle wheel, and a belt. The sheet-feeding roller is for separating a sheet with the friction device. The first idle wheel is disposed in the upstream side of the sheet-feeding roller. The belt encircles the first idle wheel and the axle of the sheet-feeding roller. The sheet-feeding module rotates from a first position to a second position when the sheet-feeding roller rotates, such that the belt contacts the sheet when the sheet-feeding module is at the second position.
Abstract:
A positioning assembly is provided with an endless loop conveyor belt for transporting an object and a first and second roller (12) arranged inside the endless loop. A first mounting part connected to a first end of the first roller (12) and a second mounting part connected to a second end of the first roller (12) are independently movable in a length direction of the conveyor with respect to the frame (15). An actuator system is provided which includes a first lateral actuator (61) arranged to move at least a part of the first roller (12) in a direction parallel to the rotational axes (106) of the first roller (12). The first roller (12) is longitudinally divided into at least two longitudinal segments. The first lateral actuator (61) moves at least one of the longitudinal segments parallel to the rotational axis (106) of the first roller (12).
Abstract:
A belt tracking system for adjusting displacement of a movable belt in an axial direction of a plurality of rollers about which the movable belt is entrained includes a slope member and a roller shaft support. The slope member is disposed at least at one end of at least one of the plurality of rollers in the axial direction, to tilt the roller due to movement of the belt. The roller shaft support rotates about a predetermined shaft and includes a shaft recovery member to recover a tilt of the slope member. The shaft recovery member is disposed within a shortest circumference of a closed curve among closed curves within which the slope member and the roller shaft support are disposed in a state in which the roller shaft support is rotated.
Abstract:
A sheet feeder includes a loading member, an attraction separation unit, and a control device. The loading member carries sheet materials. The attraction separation unit includes an endless dielectric belt, holding rollers, and an adjustment device. The endless belt attracts and holds the uppermost one of the sheet materials. The holding rollers holding the endless belt include upstream and downstream holding rollers. The upstream holding roller is rotated around a shaft of the downstream holding roller as the rotation axis in accordance with rotation of the downstream holding roller. The adjustment device provided to the upstream holding roller adjusts the movement range of the upstream holding roller in the height direction. The control device controls, in accordance with the type of sheet materials, an operation of lifting and lowering the loading member, to thereby allow the adjustment device to adjust the movement range of the upstream holding roller.
