A medium cutting device according to an embodiment may include: a fixed blade provided on one side with respect to a conveyance path in which a medium is conveyed in a thickness direction of the medium orthogonal to a surface of the medium and including a cutting edge thereof; a rotary blade provided on the other side with respect to the conveyance path in the thickness direction, and including a cutting edge thereof, wherein the rotary blade is rotatable and configured to be rotated in a rotation direction so that the cutting edge of the rotary blade passes through the cutting edge of the fixed blade to cut the medium being conveyed. The rotary blade includes, on an outer circumferential surface, a recessed portion provided on a side of the cutting edge of the rotary blade in a reverse direction opposite to the rotation direction of the rotary blade.

A printing apparatus includes: an image former that forms an image on a pre-cutting sheet; a cutter that cuts the pre-cutting sheet on which the image is formed; and a hardware processor that controls the image former, wherein the hardware processor acquires image deviation information related to a deviation of an image with respect to a post-cutting sheet, and corrects at least one of a position, a tilt, or a shape of an image formed on the pre-cutting sheet so as to eliminate the deviation of the image based on the image deviation information.

A post-processing apparatus that performs post-processing on paper in which an image is formed, the apparatus including: a paper cutter that cuts the paper in which the image is formed; a reader that reads the paper cut by the paper cutter; and a hardware processor that determines whether a cutting position of the paper cut by the paper cutter is good or not based on a read result read by the reader, wherein the hardware processor determines whether the cutting position of the paper in which partial cutting is performed is good or not, the partial cutting being cutting a portion of the paper by the paper cutter.

A reading apparatus includes a reading device and circuitry. The reading device reads a recording medium in a direction intersecting a conveyance direction of the recording medium. The circuitry detects a reference image for cutting processing of the recording medium, based on read information read by the reading device.

A printing device includes: a feeding tray on which a sheet can be mounted; a first conveying passage; an image forming unit disposed along the first conveying passage and configured to record an image on the sheet; a cutting unit disposed along the first conveying passage downstream of the image recording unit and configured to cut the sheet; a second conveying passage connected to the first conveying passage; and a controller configured to perform: conveying the sheet mounted on the feeding tray to the image recording unit; recording an image on the sheet by the image recording unit; cutting the recorded sheet at a cutting position on the sheet to divide the sheet into a first sheet on which the image has been recorded and a second sheet on which the image has not been recorded; discharging the first sheet; and conveying the second sheet to the second conveying passage.

A trimming device includes: a moving unit including a transport unit that transports a booklet which includes one or more sheets and which is folded in half at a center portion of the booklet, with a folded portion of the booklet at a front, a correction unit that corrects a posture of the booklet in response to a leading end of the booklet transported by the transport unit abutting against the correction unit, the correction unit being capable of advancing to an abutting position on a path of the booklet and retracting from the path, and an upper guide unit that extends at least between the transport unit and the correction unit, the upper guide unit that guides an upper surface of the booklet, the moving unit being movable in a transport direction between (i) a predetermined upstream position and (ii) a downstream position downstream of the upstream position in the transport direction; a lower guide unit that guides a lower surface of the booklet transported by the transport unit; and a cutting unit that cuts a downstream fore edge portion of the booklet in the transport direction, the cutting unit being capable of advancing to the path of the booklet and retracting from the path of the booklet. The upper guide unit is configured such that a gap between the upper guide unit and the lower guide unit widens in accordance with a thickness of the booklet to allow the booklet to pass through the gap.

A cutting apparatus includes a blade configured to cut a sheet that is conveyed along a sheet conveyance path, a scrap path through which scrap generated when the sheet is cut by the blade passes, a guide member configured to guide the sheet conveyed, and a blowing unit configured to blow air such that the air crosses the sheet conveyance path from a side opposite the scrap path with the sheet conveyance path therebetween, wherein the blowing unit blows air such that the air flows along the guide member positioned at a second position at which the scrap is allowed to enter the scrap path.

Provided are a finisher, a non-transitory computer-readable recording medium and a method for controlling transportation of media sheets. The finisher includes a sheet transporter, a sheet cutter for dividing each printed media sheet into multiple cut media sheets by cutting, a sheet inserter that inserts insertion sheets into the sheet path, a sheet stacker for stacking the cut media sheets and the insertion sheets transported by the sheet transporter, a sheet buffer disposed on a branch line branching off from the sheet path, and a controller. The controller sets a sheet insertion mode to a pre-sheet insertion mode or a post-sheet insertion mode, and causes the sheet transporter to transport a part of cut media sheets or an insertion sheet into the sheet buffer and change the order of the sheets in the sheet path so that the insertion sheet is positioned between the cut media sheets.

An image forming device which forms an image for color correction in the margin of a continuous recording medium such as continuous paper as appropriate without causing erroneous detection by a mark sensor at a post-processing stage. In the image forming device, a printing data generator (control section) performs: acquiring a detection criterion to detect a post-processing image for use at the post-processing stage; creating a color correction image to be used for color correction of an original image according to the detection criterion; and arranging the color correction image as an outer area image in an area other than an original image formation area in printing data.

A printing device includes: a feeding tray on which a sheet can be mounted; a first conveying passage; an image forming unit disposed along the first conveying passage and configured to record an image on the sheet; a cutting unit disposed along the first conveying passage downstream of the image recording unit and configured to cut the sheet; a second conveying passage connected to the first conveying passage; and a controller configured to perform: conveying the sheet mounted on the feeding tray to the image recording unit; recording an image on the sheet by the image recording unit; cutting the recorded sheet at a cutting position on the sheet to divide the sheet into a first sheet on which the image has been recorded and a second sheet on which the image has not been recorded; discharging the first sheet; and conveying the second sheet to the second conveying passage.
