A sheet discharge device includes: a conveying portion which conveys the sheet in a conveying direction with the sheet interposed between a first roller and a second roller; a first conveying guide; a second conveying guide; a rotating portion which is disposed on a shaft of the first roller and has an outer diameter larger than that of the first roller; and a guide portion which is provided in the first conveying guide and in which an interval between the guide portion and the opposite second conveying guide becomes narrower toward a downstream side in the conveying direction, the guide portion being located at a position corresponding to the rotating portion in a sheet width direction orthogonal to the conveying direction.

A method of stacking a plurality of absorbent sheet products is provided. In an embodiment, the method includes folding an absorbent sheet inwardly along a first folding line to form a first inner panel, folding the absorbent sheet inwardly along a second folding line, substantially parallel to the first folding line, to form a second inner panel, folding the absorbent sheet along a third folding line substantially perpendicular to the first and the second folding lines to form a first outer panel and a second outer panel, sandwiching the first and the second inner panels therebetween to obtain one of the absorbent sheet products, and inserting at least a section of at least one of the first and the second outer panels of each one of the absorbent sheet products between the first and the second outer panels of an adjacent one of absorbent sheet products of the stack.

A sheet conveyor is provided for transporting a sheet. The sheet conveyor includes a supplying conveyor, a receiving conveyor and a sheet guidance unit. The receiving conveyor includes a support surface arranged for supporting the sheet on a contact side of the sheet and an attraction unit arranged for attracting the sheet to the support surface. The supplying conveyor includes a transport belt being arranged for advancing the sheet in a transport direction along a transport path towards the support surface of the receiving conveyor; the sheet having two side edge portions relative to the transport path. The sheet guidance unit is arranged at a downstream end of the transport path for guiding the sheet towards the receiving conveyor, wherein said sheet guidance unit includes a lifting element arranged for lifting both side edge portions of the sheet away from the support surface while a middle portion of the sheet in between both side edge portions is guided towards the support surface.

A sheet transport device includes a pair of movable transport rollers capable of transporting a sheet while holding the sheet and moving in an axial direction crossing a transportation direction; pairs of first transport rollers upstream from the pair of movable transport rollers in the transportation direction while being spaced apart from each other to transport the sheet while holding the sheet; and pairs of transport guides to define sheet transport spaces between the pair of movable transport rollers and the pairs of first transport rollers and between the pairs of first transport rollers. When the pair of movable transport rollers is to be moved in the axial direction, at least one pair of first transport rollers transports the sheet while bending the sheet in the transport space by producing a difference in transport rate within a portion of a section upstream from the pair of movable transport rollers.

A medium ejection device includes a lever that is movably disposed at the position of a pair of ejection rollers including a first roller and a second roller that nip and eject a medium and moves from one of the rollers to another of the rollers to push the medium, a lever position adjustment unit that moves the lever in a movement direction to adjust an advance position, and a motor that transmits power to the pair of ejection rollers. When turning forward, the motor rotates the pair of ejection rollers in the direction in which the medium is ejected. When turning backward, the motor transmits power to the lever position adjustment unit and moves the lever.
