Provided is a stacker including a stacking shelf on which printed paper from a printer is received and stacked, a lifting and lowering mechanism that lifts and lowers the stacking shelf, and a stacker control unit that controls the lifting and lowering mechanism. The stacker control unit controls the lifting and lowering mechanism to lift and lower the stacking shelf to a first predetermined height corresponding to the printer at a receiving position for receiving the paper from the printer, and to lift and lower the stacking shelf to a second predetermined height corresponding to a sheet processing machine at a paper supply position for supplying paper to the sheet processing machine, the paper supply position being different from the receiving position.

A three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.

The present invention makes it possible to perform both judgment of necessity of maintenance of a circulation-type paper sheet storage device and the maintenance of the circulation-type paper sheet storage device in the same place. The paper sheet storage device is a paper sheet storage device attached to a paper sheet processing device having a storage function for receiving paper sheets transported thereto and storing the paper sheets in the paper sheet storage device and/or a feeding function for feeding paper sheets stored in the paper sheet storage device. The paper sheet storage device includes a memory unit that memorizes therein specific information to be updated according to storage or feed of paper sheets.

Provided is a sheet stacking apparatus including an aligning member lifting-lowering device configured to lift and lower aligning members between an aligning position where the aligning members abut to and align the sheets and a retreating position where the aligning members are lifted from an upper surface of the sheets, an aligning member moving device configured to move the aligning members in a sheet width direction, and a stack tray lifting-lowering device configured to lift and lower a stack tray based on a detection result of a sheet surface detecting device. A controller lifts the aligning members to the retreating position with the aligning member lifting-lowering device after the sheets stacked on the stack tray is aligned at the aligning position, and stops lifting-lowering operation of the stack tray lifting-lowering device while the aligning members are moved in the sheet width direction with the aligning member moving device.

A sheet transport device includes a loading unit at which a sheet to be conveyed is loaded, a transport unit configured to impart to the sheet loaded at a sheet loading surface of the loading unit a transport force for transporting the sheet toward an alignment unit, and an adjustment unit configured to adjust the transport force. The adjustment unit includes a movable loading unit formed so that at least part of the sheet loading surface is configured to protrude toward the transport unit and a driving unit configured to displace the movable loading unit in a protruding direction and a retracting direction.

Container assembly for collecting pads, such as cosmetic pads or medical pads, wherein the container assembly comprises an elongate shell extending along a collecting axis parallel to a stacking direction and in a circumferential direction about the collecting axis, wherein the shell comprises a top side, a bottom side opposite to said top side in the stacking direction, wherein the shell is open at said top side for receiving the pads in said stacking direction and along said collecting axis, wherein the shell comprises a first shell segment and a second shell segment extending along said collecting axis between the top side and the bottom side and movable relative to one another in a clamping direction transverse to the stacking direction, wherein the second shell segment is biased relative to and towards the first shell segment in said clamping direction.

A sheet stacking device include a guide unit and a blower. The guide unit receives a downstream end of a sheet in a sheet conveyance direction and guides the sheet downstream in the sheet conveyance direction. The blower blows air toward the sheet guided by the guide unit. A region of the blower from which the air is blown is changeable in response to a size of the sheet.

A paper stacking device includes: a stacker on which paper is stacked; a paper ejector that ejects the paper toward the stacker; an aligning plate that is provided on a side of the paper stacked on the stacker, and aligns a side end of the paper; and a paper floating member that is provided in the aligning plate, and supports, from below, the side end of the paper ejected from the paper ejector, wherein the paper floating member is switched, in conjunction with a movement in upward and downward directions of the aligning plate, between: a paper floating position that advances from a side of the side end of the paper to an ejection route of the paper, and causes the paper ejected from the paper ejector to float from uppermost paper stacked on the stacker; and a retreat position that retreats from the ejection route.
