A post-processing device includes a processing tray, an aligning plate, a transport section, a feeding section, and a pressing section. A sheet before being subjected to stapling processing by a stapler is to be mounted on the processing tray. The aligning plate aligns ends of a plurality of sheets. The transport section transports the sheet toward the aligning plate. The feeding section is provided between the transport section and the aligning plate and feeds the sheet in a transport direction. The pressing section is provided between the transport section and the aligning plate and applies, to the sheet, a pressing force having a component in a direction opposite from the transport direction. Further, the pressing section applies the pressing force to the sheet before the feeding section applies a feeding force to the sheet.

Post-processing device

A sheet transport device includes a loading unit at which a sheet to be conveyed is loaded, a transport unit configured to impart to the sheet loaded at a sheet loading surface of the loading unit a transport force for transporting the sheet toward an alignment unit, and an adjustment unit configured to adjust the transport force. The adjustment unit includes a movable loading unit formed so that at least part of the sheet loading surface is configured to protrude toward the transport unit and a driving unit configured to displace the movable loading unit in a protruding direction and a retracting direction.

Sheet transport device and method of controlling sheet transport device preliminary class

A post-processing device includes a processing tray on which a medium on which recording was performed by a recording unit is loaded, a rear end alignment unit that aligns a rear end (an example of an end portion) of the medium on the processing tray, a post-processing unit that performs post-processing on the medium aligned by the rear end alignment unit, and a pressing member that presses the rear end of the medium. The post-processing unit is configured to be movable. The pressing member is provided to be rotatable in conjunction with movement of the post-processing unit, in a state in which the pressing member is in contact with the medium aligned by the rear end alignment unit.

An end unit includes: a processing tray including an upper surface on which a medium subjected to recording by a recording unit is mounted; a first paddle and a second paddle that transport, in direction +A, the medium mounted on the upper surface; an alignment section that aligns an edge portion of the medium, which was transported in direction +A by the first paddle and the second paddle, in direction +A; a post-processing section that performs post-processing for the medium aligned by the alignment section; and a load member that applies a load when the medium on the processing tray moves in direction &#x2212;A opposite to direction +A.

Post-processing device and recording system

A printing system includes a printing unit, a position determiner that randomly determines a position where a first information code is to be set, a modifier that modifies print data for printing an image, the first information code, and a positional information code having recorded therein positional information at the time of printing that indicates the position determined by the position determiner so that the first information code is set at the position determined by the position determiner, an acquirer that acquires the position of the first information code on a print medium as positional information and acquires the positional information at the time of the printing from the positional information code, and a determiner that determines whether the printing result is a falsified matter based on comparison of the positional information after the printing with the positional information at the time of the printing.

Printing system and printing determination method

A medium loading device includes a side end aligning member which is positioned at a standby position when a medium is ejected; and a control section. When a value based on first information relating to recording density of a medium to be ejected this time and at least one medium among the media ejected previously is equal to or greater than a threshold value, the control section specifies a first position, which overlaps the medium to be ejected this time, as the standby position, and when the value based on the first information is less than the threshold value, the control section specifies a second position, which does not overlap the medium to be ejected this time, as the standby position, and the control section adjusts the threshold value based on second information relating to at least one medium among the media recorded before the ejection at this time.

Medium loading device and image forming system

A post-processing device includes a processing tray on which a medium recorded by a recording portion is loaded, and a first paddle which is an example of a transportation member provided above the processing tray and rotating to transport the medium toward the upstream in a transport direction. In addition, the post-processing device includes a roller which is an example of a rotating body provided above the rotation shaft of the first paddle, and a paddle unit frame which is an example of an upper member provided above the roller. The roller and the paddle unit frame are positioned within a rotation locus of the first paddle.

A printer includes a housing, a cover, and a movable unit. The housing has a space and an opening. The space accommodates a transportation path section that is at least part of a transportation path for transporting a paper sheet. The opening allows the space to communicate with the outside of the housing. The cover is in any one of positions relative to the opening including a closed position where the cover covers the opening and an open position where the cover uncovers the opening. The movable unit has the transportation path section and is movable between a storage position where the transportation path section is stored in the space and a pulled-out position where the transportation path section is pulled out of the space. The movable unit in the pulled-out position is restrained from moving toward the storage position when the cover is in the open position.
