(54)Accumulating unit and print product production device


(57) [Object] To provide an accumulating unit capable of overlaying a sheet stacked body in a good posture even during high speed operation, and to provide a print product production device.
[Means for Solving] A sheet accumulating part 40 comprises: a front positioning part 44 that is provided on a front side in a carrying-in direction of a sheet (for example, a signature S) carried into the sheet accumulating part 40 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 44 on a rear side in the carrying-in direction of the sheet and that positions a rear edge in the carrying-in direction of the sheet. The front positioning part 44 is configured to, when the sheet has entered the sheet accumulating part 40, move away from the 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 he 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 44, move closer to the rear positioning part 46 such that the distance of the front positioning part 44 from the rear positioning part 46 is substantially equal to the length of the sheet in the carrying-in direction of the sheet.
