Provided is a sheet processing apparatus, including: a placement portion to which a sheet conveyed by a conveyance portion in a conveyance direction is placed; a processing portion configured to perform predetermined processing on a sheet placed on the placement portion, and to be movable in a predetermined moving range; and a control portion configured to control the processing portion to position, at a timing at which a sheet conveyed by the conveyance portion passes through the moving range, from a first position of preventing from interfering with the sheet to a second position of performing the predetermined processing on a preceding sheet having been conveyed by the conveyance portion and placed on the placement portion before the sheet.

A post-processing apparatus for post-processing paper discharged from an image forming apparatus comprises: a paper discharging roller for conveying both first and second paper sequentially discharged from an image forming apparatus to an intermediate loading part; a main paddle part for conveying the first and second paper loaded on the intermediate loading part to a compiling region; a reverse roller for conveying, together with the main paddle part, the first and second paper to the compiling region; and a binding part for processing the first and second paper conveyed to the compiling region, the paper discharging roller allows the first paper to stand by on a standby path, and conveys the first and second paper to the intermediate loading part in a state in which the leading end of the first paper protrudes further than the leading end of the second paper.

A bag-making and packaging machine includes a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film roll holding unit that rotatably holds a first film roll, a film temporary placement member on which a vicinity of a leading end portion of a first film wound into the first film roll is manually temporarily placed when attaching the first film roll to the film roll holding unit, a leading end portion detection sensor configured to detect that the leading end portion of the first film is positioned in a prescribed position, and a controller configured to control a rotating mechanism to convey the first film along a predetermined conveyance path until the leading end portion detection sensor detects that the leading end portion of the first film is positioned in the prescribed position.

A conveyance device holds a sheet medium in a roll and includes a drive roller that feeds the sheet medium from the roll to a conveyance path; and a roll rotating unit that rotates the roll forward to convey the sheet medium toward the drive roller and in reverse to rewind the sheet medium and that has multiple drive modes with different speeds of rotation. A control unit controls driving the drive roller and the roll rotating unit, such that, when starting a reverse conveyance operation that rewinds the sheet medium, the control unit selects the drive mode to be used in the reverse conveyance operation based on a first conveyance distance, which is the distance the sheet medium is to be conveyed in the reverse conveyance operation, and the diameter of the roll stored as roll diameter information and as calculated after an immediately previous reverse conveyance operation.

A stacker includes a medium stacking portion for receiving and stacking a medium processed and discharged by a processing unit, a medium butting portion for aligning the medium by contacting a leading end of the medium, and a paddle that includes a feeding portion and is for transporting the medium received by the medium stacking portion in a direction toward the medium butting portion by rotating. Furthermore, the stacker has a first mode in which the paddle stops in a state in which the feeding portion does not contact the medium on the medium stacking portion and a second mode in which the paddle stops in a state in which the feeding portion comes into contact with the medium on the medium stacking portion and is deformed.

In one example, an elevator for a roll of print media includes rotatable shafts oriented parallel to one another and translatable supports to support a roll of print media. Each support is operatively connected to the shafts such that rotating the shafts in a first direction raises the supports and rotating the shafts in a second direction opposite the first direction lowers the supports.

A print device includes a supply unit, a print unit, a conveyer, a tensioner, a drive unit, a processor, a medium detector, and a memory. The tensioner is configured to apply tension to the medium. The memory stores computer-readable instructions that, when executed by the processor, instruct the processor to perform processes including correction processing, which is repeated a plurality of times, of controlling the drive unit and applying the tension to the medium by the tensioner during a back-and-forth conveyance operation of conveying the medium in the return direction after conveying the medium in the conveyance direction, and detection processing of detecting attributes of the medium, based on the detection result output from the medium detector, during one of the back-and-forth conveyance operations, of the plurality of back-and-forth conveyance operations.

A sheet processing includes a first conveyance path, a buffering portion, a second conveyance path, a conveyance roller pair, a supporting portion, a moving member, a regulating portion, and a processing unit. The buffering portion is configured to superimpose a first sheet and a second sheet on each other in a state of being offset from each other in a sheet conveyance direction. An offset amount, by which a leading end of the first sheet in the sheet conveyance direction projects downstream in the sheet conveyance direction with respect to a leading end of the second sheet in the sheet conveyance direction in a state before the first sheet and the second sheet are discharged onto the supporting portion, is larger than a distance from a sheet contact position of the moving member to the regulating portion in the sheet conveyance direction.

A printer apparatus includes a printer main body having a platen roller and a print head to print on recording paper, a cutter unit configured to cut the recording paper, and a presenter unit connected to the cutter unit, wherein the recording paper on which the print head has printed enters the presenter unit through the cutter unit, and comes out from a discharge slot of the presenter unit, wherein the presenter unit includes a first roller and a second roller configured to convey the recording paper placed therebetween, and a flapper disposed along a transportation path of the recording paper between the cutter unit and both the first roller and the second roller, and configured to be flipped open to an outside of the presenter unit to expose the transportation path, wherein an angle at which the flapper is open is selectively set to one of a plurality of different angles.

A sheet feeding apparatus is provided with a pick-up roller that contacts sheets loaded on a load tray to pick up, a paper feed roller that feeds a picked-up sheet, and a separation roller brought into press-contact with the paper feed roller to separate the sheet, where the sheets are separated from the pick-up roller, the separation roller is rotated in a sheet return direction different from a sheet feed direction, and subsequently, the paper feed roller is separated from the separation roller. It is possible to prevent damage to a sheet and sheet jam from occurring in pulling out the load tray loaded with sheets to the front side.
