According to one or more embodiments, a sheet conveying device includes a reading device, a roller, a downstream guide, and a transition guide. The reading device reads a surface of the sheet. The roller faces the reading device. The downstream guide is downstream of the roller in the sheet conveyance direction. The transition guide guides the sheet at least during a sheet transition from the reading position to s an upstream end of the downstream guide.

The invention relates to a device, in particular a roll cross-cutter, for forming a shingle stream of underlapping or overlapping sheets, in particular of paper or carton sheets, having a transport apparatus for transporting sheets, having a shingling apparatus for underlapping or overlapping sheets in regions, having a deceleration apparatus, downstream of the shingling apparatus in the transport direction of the sheets, for decelerating shingled sheets, in particular by forming a deceleration gap for the passage of shingled, combined sheets, and, preferably, having a cross-cutting apparatus upstream of the shingling apparatus for cutting a material web into individual sheets. According to the invention, the shingling apparatus is designed to be adjustable, in dependence of the cut length, in and/or opposite the transport direction of the sheets.

To prevent erroneous transfer onto a paper sheet loading platform and improve the operation stability over the entire length of a long-edge direction of a pressing member by ensuring a long time during which the pressing member continues to push in a paper sheet alone. To include two rotating bodies 120 and 130 that have recesses 120a and 130a and are rotatable in opposite directions to each other in synchronization with each other, a pressing member 140 that is movable and presses an intermediate portion of a back of a paper sheet forward, a drive mechanism 180, and a paper sheet loading platform 200. The drive mechanism rotates each rotating body by an angle from 195 degrees to 270 degrees in a time period after the pressing member starts to bring a center of the paper sheet into contact with the paper sheet loading platform from an initial state until the pressing member leaves the center of the paper sheet.

A sheet stacking device includes a sheet outlet, a lower discharge roller, and a paddle member. The paddle member is disposed coaxially to a rotation shaft of the lower discharge roller, and is driven to rotate independently of the lower discharge roller in the same direction as the lower discharge roller, so as to contact downward an upstream part in a discharging direction of a sheet discharged through the sheet outlet. The paddle member includes a base part in which the rotation shaft is inserted, an arm part protruding in a direction separating from an axis center of the base part, and a paddle elastic part protruding from the arm part. A rotation speed of the paddle member is the same as a rotation speed of a discharge roller pair when the sheet passes through a nip of the discharge roller pair.

The invention relates to an apparatus, in particular a roll cross cutter, for forming a shingled stream of underlapping or overlapping sheets, in particular paper or cardboard sheets, comprising a transport device for transporting sheets, a shingling device for underlapping or overlapping of the sheets at least in some regions, a braking device following the shingling device in the transport direction of the sheets for braking of shingled sheets, in particular by the formation of a brake gap for the passage of sheets brought together in a shingled manner, and a cross-cutting device upstream of the shingling device for cutting a material strip into individual sheets. According to the invention, an intake section is provided between the shingling device and the braking device for intake and further transport of a sheet, trailing in the shingled stream, into the braking device.

A document sheet transportation device includes a feeding portion which feeds a document sheet from a document sheet placement portion toward a document sheet transportation path. The feeding portion includes a holder, a feeding member, a supporting body supported by the holder, a rotatable stopper member having a contact end portion allowed to contact a front end of a document sheet, and a biasing member which applies a biasing force to the stopper member. The stopper member is allowed to change a position among a first position in which the contact end portion contacts the front end of the document sheet, a second position which allows feeding of the document sheet by the feeding member, and a third position which is rotated in the first rotating direction from the second position. The biasing member applies the biasing force to the stopper member in a reverse second rotating direction.

The present invention includes a lift portion lifting and inverting a sheet group including a plurality of stacked sheets and a conveyor portion that moves, along a conveying direction, each sheet transferred from the lift portion, wherein: the lift portion includes frames, a fork portion, an inversion mechanism turning the fork portion to lift and invert the sheet group, and a fork movement mechanism moving the fork portion; the lift portion is equipped with a width direction movement mechanism moving the sheet group in a width direction; and after the sheet group is mounted on the fork portion and before the sheet group is transferred to the conveyor portion, the width direction movement mechanism is controlled on the basis of detection information from a position sensor to center the sheet group within a reference width direction range.

In some embodiments, methods and systems are provided for improved handling of lithography masks including loading a mask via a first load port from a first carrier; inverting the mask using a first contact pad; cleaning the mask; inverting the mask using a second contact pad; and unloading the mask via a second load port into a second carrier. Numerous other aspects are provided.

A sheet conveying apparatus includes a first roller pair conveying a sheet, a second roller pair provided downstream, in a sheet conveying direction, of the first roller pair, and a moving member having an abutment portion. The moving member moves from an abutment position in a sheet conveying path upstream of a nip portion of the second roller pair to a passing position at which the sheet conveyed by the first roller pair is allowed to pass through. In a case where a first sheet and a second sheet are conveyed successively by the first roller pair, when the moving member is at the abutment position in which the abutment portion is pushed by the second sheet while the first sheet is conveyed by the second roller pair, a rear end of the first sheet is located upstream of the nip portion of the second roller pair.
