A conveyance mechanism includes: a lower conveyance guide disposed below an inclined conveyance path having an upward inclination or a downward inclination with which a sheet material is to be conveyed, and to guide a lower surface of the sheet material; an upper conveyance guide located above the inclined conveyance path, and to guide an upper surface of the sheet-shaped material, the upper conveyance guide being openable and closable about a rotation shaft, which is disposed on a side of the inclined conveyance path in a direction of a width of the inclined conveyance path so as to extend along the inclined conveyance path; and a first urging member to urge a portion of the upper conveyance guide away from the rotation shaft in the direction of the width of the inclined conveyance path toward the rotation shaft, the portion of the upper conveyance guide away from the rotation shaft being at an upper end of the upper conveyance guide in an inclined direction.

A sheet processing machine has at least one shaping device and at least one sheet delivery unit, arranged downstream of the at least one shaping device along a transport path provided for a transport of sheets. The at least one shaping device has at least one shaping point which is formed by at least one forme cylinder, on one hand, and at least one impression cylinder, on the other hand. At least one separation device, for removing scrap pieces from sheets, is arranged downstream of the at least one shaping point along the transport path provided for the transport of sheets. The at least one separation device has at least one separation transport device. At least one transport device, configured as a selective transport device, is arranged following the at least one separation transport device along the transport path provided for the transport of sheets. The transport device is configured as at least one upper suction transport device for a hanging transport of sheets.

A veneer sheet feed device for multistage veneer sheet dryer is provided between an auto feeder including a carry-in conveyor and a roll dryer (veneer sheet dryer). The veneer sheet feed device is provided with a guide member and a feed conveyor for feeding a veneer sheet carried in from the carry-in conveyor to each conveyance unit of the roll dryer in this order from a conveyance up stream side. The veneer sheet feed device further provided with a pivot mechanism that allows a starting end of the guide member belonging to the conveyance stage immediately above the conveyance stage in which the veneer sheet is carried this time from the carry-in conveyor to pivot to a portion above a horizontal position of a roller shaft located at a terminal end of this guide member.

A sheet feeding device includes a pickup roller, a feed roller, a retard roller, a conveyance rollers pair. The pickup roller contacts a sheet at a first contact point in a pickup position and rotates to convey the sheet in a predetermined conveyance direction. The feed roller is disposed on a downstream side of the pickup roller in the conveyance direction. The retard roller contacts the feed roller at a second contact point and conveys the sheet while separating the sheet. The conveyance rollers pair contacts each other at a third contact point and conveys the sheet passing through the second contact point to a conveyance path. The first contact point, the second contact point and the third contact point are disposed on a linear line in the conveyance direction, when viewed from axial directions of the rollers.

A paper sorting device includes: a stacking conveyor that receives continuously fed cut sheets to stack the cut sheets by sorting unit and that continuously conveys stacked cut sheets downstream on a unit-by-unit basis; and a stacker section arranged downstream of the stacking conveyor, capable of continuously stacking the stacked cut sheets conveyed from the stacking conveyor, at different positions on a placement surface.

A sheet processing machine has at least one shaping device and at least one sheet delivery unit, arranged downstream of the at least one shaping device along a transport path provided for a transport of sheets. The at least one shaping device has at least one shaping point which is formed by at least one forme cylinder, on one hand, and at least one impression cylinder, on the other hand. At least one separation device, for removing scrap pieces from sheets, is arranged downstream of the at least one shaping point along the transport path provided for the transport of sheets. The at least one separation device has at least one separation transport device. At least one transport device, configured as a selective transport device, is arranged following the at least one separation transport device along the transport path provided for the transport of sheets. The transport device is configured as at least one upper suction transport device for a hanging transport of sheets.

An image forming apparatus includes an image forming unit to form an image on a sheet, a conveyance roller, a motor, a gear train, a detection unit to detect motor driving current, a phase determination unit to determine a motor rotor rotation phase, and a control unit having first and second control modes. The control unit rotates the rotor to rotate the conveyance roller in a predetermined direction, and rotates the conveyance roller in a direction opposite to the predetermined direction. The control unit controls the driving current in the second control mode, and then switches, in response to a value corresponding to a rotor rotation speed having reached a target speed, from the second control mode to the first control mode to control the driving current. The target speed is a speed which corresponds to a speed when the conveyance roller conveys the sheet and is a constant value.

A single nip de-skew, lateral registration, and process direction registration device removes skew, laterally registers, and registers in the process direction substrates moving along a media transport path. The single nip de-skew, lateral registration, and process direction registration device includes a fixed roller that is longer than a rotating wheel that forms a nip with the fixed roller. The wheel has a coefficient of friction that is higher than a coefficient of friction of the roller so an actuator translating the wheel along the fixed roller laterally registers and de-skews substrates.

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

A sheet feeding device includes a pickup roller, a feed roller, a retard roller, a conveyance rollers pair. The pickup roller contacts a sheet at a first contact point in a pickup position and rotates to convey the sheet in a predetermined conveyance direction. The feed roller is disposed on a downstream side of the pickup roller in the conveyance direction. The retard roller contacts the feed roller at a second contact point and conveys the sheet while separating the sheet. The conveyance rollers pair contacts each other at a third contact point and conveys the sheet passing through the second contact point to a conveyance path. The first contact point, the second contact point and the third contact point are disposed on a linear line in the conveyance direction, when viewed from axial directions of the rollers.
