  • Patent number: 6934507
    Abstract: Provided is an image forming apparatus, in which liable to produce remaining curl, highly effective curl correction is performed. The image forming apparatus includes: a roll receiving portion for receiving a continuous recording sheet wound into a roll shape; a sheet transporting portion for transporting the continuous recording sheet from the roll receiving portion; a cutting portion for cutting the continuous recording sheet sent out into a desired size; an image forming portion for forming a toner image on the recording sheet (which has been cut); a fixing portion for fixing the toner image to the recording sheet by heating the recording sheet on which the toner image is formed; a cooling portion for cooling the recording sheet to which the toner image has been fixed; and a curl correcting portion for correcting a curl of the recording sheet when the recording sheet is cooled.

  • Publication number: 20040221698
    Abstract: An improved and more efficient perforation method for creating multiple punch holes during a finishing process of paper sheets and other sheet materials. A highlight of the present invention is the ability to select between at least two configurations of punch holes automatically, without manual adjustment, and “on-the-fly” without interruption of the sheet or paper flow. The perforation method utilizes two rotatable punches set at different angles such that when one intersects the sheet path, the other clears the sheet path. The speed of rotation is controlled such that the non-selected punch intersects the sheet path in a space between pitches.

  • Patent number: 6745657
    Abstract: A sheet feeding device of the present invention includes a cutter capable of being moved back and forth by hand between two reference positions outside of a sheet conveyance range. When the cutter is held in a halt at a position other than the reference positions, the sheet feeding device returns a sheet toward the upstream side by a preselected amount and then returns the cutter to one of the reference positions. Even when the cutter moved by hand for the replacement or the replenishment of a sheet is left in the sheet conveyance range, the cutter is prevented from again cutting the leading edge of the sheet when returning to the reference position. This protects the leading edge of the sheet from defective cutting.

  • Patent number: 6519441
    Abstract: When a roll paper unit 200 is incorporated into an image formation apparatus, a second outlet guide member 92 is turned around a pivot 92a in the direction of an arrow G, i.e., moved from a position of solid lines to a position of two-dot chain lines, a rear end portion 92b of this second outlet guide member 92 pressing down a front end portion 80c of a guide member 80 to cause the guide member 80 to be turned around a central shaft 80d in the direction of an arrow H, i.e., moved from a position of solid lines to a position of two-dot chain line. Consequently, a path extending in the direction of an arrow C is closed, while a path extending in the direction of an arrow F is opened, the roll paper 72 being transferred in the paper feed direction. When the roll paper unit 200 is drawn out, the second outlet guide member 92 and the guide member 80 are turned in the directions opposite to those mentioned above.

  • Patent number: 6454150
    Abstract: A method and device for improving the throughput of a continuous web cutter, which is operated in move-and-pause cycles to allow the web to be cut into cut sheets. To avoid tear and web breakage, the web is fed at a low cycle rate at the starting stage. The cycle rate is progressively increased. When a feed rhythm is developed at the higher cycle rate, a constant cycle rate is maintained for the rest of the web operation.
