Abstract:
1. A post-processing device comprising: a transport section that transports a sheet transported at a predetermined speed from an upstream side toward a downstream side; a load section on which the sheet transported from the transport section is loaded; a first aligner that moves the sheet transported to the load section while being in contact with a surface of the sheet so as to perform an alignment process on the sheet; a second aligner that moves the sheet transported to the load section while being in contact with an edge of the sheet so as to perform an alignment process on the sheet; an alignment controller that performs control such that the first aligner and the second aligner perform the alignment process on the sheet transported to the load section based on a first mode in which the second aligner performs the alignment process while the first aligner performs the alignment process on the sheet, and such that the first aligner and the second aligner perform the alignment process on the sheet transported to the load section based on a second mode, for every predetermined number of sheets, in which one of the first aligner and the second aligner performs the alignment process on the sheet after the other aligner completes the alignment process; and a transport controller that controls the transport section by causing the transport section to transport the sheet at a reduced speed relative to the predetermined speed for the every predetermined number of sheets so that the sheet transported at the reduced speed reaches the load section after completion of the alignment process based on the second mode performed after a previous sheet transported immediately prior to the sheet is loaded on the load section.
