    摘要: Provided is a sheet feeder, which includes: a sheet placing table; a rotary body which is movable and sends out sheets; a sheet placement detection portion for detecting placement of sheets; an upper limit detection portion for detecting that the rotary body has reached an upper limit position; a transport detection portion for detecting transport of sheets; and a control part which rotates the rotary body so as to perform sheet feeding operation regardless of a detection state of the upper limit detection portion when sheets are set on the sheet placing table, determines that a non-feed jam has occurred when no sheet arriving is detected, and stops rotating the rotary body by determining that the sheet feeder is brought into a sheet feeding restriction state, when sheets are set again on the sheet placing table and the rotary body is detected to be in the upper limit position.

    摘要: A post-processing apparatus includes a second sheet conveying portion that conveys a paper sheet, a movement portion that displaces in a displacement direction that is different from the conveying direction of the paper sheet in the second conveying portion, a sheet edge detection portion that is disposed on the movement portion and detects the position of the paper sheet, a punching processing portion that is disposed on the movement portion, and that executes a punching process at a predetermined position on the paper sheet based on the position of the paper sheet detected by the sheet edge detection portion, and a post-processing control portion that controls the second sheet conveying portion to stop the conveying of the paper sheet when the sheet edge detection portion detects that the paper sheet is positioned on an abnormal conveying path that diverges from a normal conveying path within a conveying path region.

    摘要: The folding device includes a folding unit and a prior moving unit. The folding unit performs the folding process on the paper aligned by the alignment member positioned at the folding position. The prior moving unit moves the alignment member from the folding position to the home position or the alignment position according to a position of the end of the paper being moved in the folding process. This can put ahead the starting time for moving the alignment members and reduce the time required for a subsequent folding process, thereby improving efficiency (productivity) of the folding process as a whole.

    摘要: A post-processing device includes a processing tray on which sheets are to be stacked, a transport portion for transporting, a sheet introduced through an introduction port, a turn-aside portion for turning aside the sheet to delay arrival of the sheet at the processing tray, and a delivery mechanism for delivering the sheets stacked on the processing tray to a delivery tray on a boundary between copies. When a remaining number of sheets of one copy unstacked on the processing tray exceeds a maximum number of stacked sheets that is an amount of sheets stackable on the processing tray, the delivery mechanism delivers a sheet stack of the one copy a plurality of times so as to avoid delivery of only one sheet on a last page of the one copy, and the turn-aside portion turns aside a sheet on a first page to be stacked after delivering the sheet bundle.
