Abstract
In a sheet or signature (printer folder sheet) accumulating a front positioning part 44 configured, when a sheet has entered a sheet accumulating part 40, to move away from a rear positioning part 46 such that a distance of the front positioning part 44 from the rear positioning part 46 is larger than a length of the sheet in a carrying-in direction of the sheet, and, after a front edge in the carrying-in direction of the sheet has contacted the front positioning part 44, to move closer to the rear positioning part 46.
Claims18
An accumulating unit for accumulating in a sheet accumulating part an individual or signature form sheet carried from an upstream side,
- the sheet accumulating part comprising:
- a front positioning part (44) that is provided on a front side in a carrying-in direction of the sheet carried into said sheet accumulating part and that positions a front edge in the carrying-in direction of the sheet;
- and
- a rear positioning part (46) that is provided facing the front positioning part on a rear side in the carrying-in direction of said sheet and that positions a rear edge in the carrying-in direction of the sheet,
- the front positioning part being configured to, when the sheet has entered the sheet accumulating part, move away from the rear positioning part such that a distance of the front positioning part from the rear positioning part is larger than a length of the sheet in the carrying-in direction of the sheet, and, after the front edge in the carrying-in direction of the sheet has contacted the front positioning part, move closer to the rear positioning part such that the distance of the front positioning part from the rear positioning part is substantially equal to the length of the sheet in the carrying-in direction of the sheet.
2 more elements
A print product production device, comprising:
- an upstream side conveyor part that conveys an individual or signature form sheet on which printing has been performed;
- a plurality of accumulating units;
- and
- a distributing and conveying part that is provided between the upstream side conveyor part and the plurality of accumulating units and that distributes and conveys the sheet conveyed by the upstream side conveyor part to each of the plurality of accumulating units,
- the plurality of accumulating units each accumulating unit comprising:
- a front positioning part (44) that is provided on a front side in a carrying-in direction of the sheet carried into said sheet accumulating part and that positions a front edge in the carrying-in direction of the sheet;
- and
- a rear positioning part (46) that is provided facing the front positioning part on a rear side in the carrying-in direction of said sheet and that positions a rear edge in the carrying-in direction of the sheet,
- the front positioning part being configured to, when the sheet has entered the sheet accumulating part, move away from the rear positioning part such that a distance of the front positioning part from the rear positioning part is larger than a length of the sheet in the carrying-in direction of the sheet, and, after the front edge in the carrying-in direction of the sheet has contacted the front positioning part, move closer to the rear positioning part such that the distance of the front positioning part from the rear positioning part is substantially equal to the length of the sheet in the carrying-in direction of the sheet.
