  • Patent number: 8437684
    Abstract: In case of both sides printing, the sheet S having an image formed on the obverse surface is conveyed to the first reversal section of the reversal device 50 disposed in a reversal path R3. In the first reversal section, the sheet S is conveyed to a U-turn reversal path by the reversal roller 56 with the first side section of the sheet S as the leading edge section. In the U-turn reversal path, a position of the first side surface section and a position of the second side surface section of the sheet S are exchanged and the sheet S is conveyed to the second reversal section. In the second reversal section, the sheet having been turned over is fed again to the register rollers 16 with a leading edge section at image forming on the obverse surface as the leading edge side. Whereby the same edge of the sheet S contacts with the register rollers 16 when the image is formed on the obverse side and when the image is formed on the reverse side.

  • Patent number: 8430586
    Abstract: A disabled state in which sheets cannot be discharged at a discharge unit while printing is detected. Upon detecting the disabled state, printing is continued at a printing unit, and a sheet printed upon is evacuated to a storage unit without cutting into a plurality of cut sheets at a cutter unit. After the disabled state is resolved, the sheet which has been evacuated to the storage unit is sent to the cutter unit so as to be cut into the cut sheets, and discharged at the discharge unit.

The document track includes a second, return path extending from a location at the selector gate to a location before the processing device. A bi-directional drive mechanism receives the document as the document passes through the selector gate in the forward direction. A gate actuator selectively moves the selector gate. Upon the bi-directional drive mechanism reversing direction after receiving the document to drive the document in the reverse direction, when the selector gate is in the first position, the selector gate diverts the document into the return path and re-introduces the document to the processing device with the document now in a reverse orientation. When the selector gate is in the second position, the selector gate allows the document traveling in the reverse direction to be re-introduced, in reverse, to the processing device.

  • Patent number: 8196921
    Abstract: In one example, a sheet handling device includes: a first mechanism configured to receive a flexible sheet moving in a first direction in a first orientation and turn the sheet to a second direction; a second mechanism configured to receive the sheet moving in the second direction, turn the sheet to a third direction and simultaneously reorient the sheet to a second orientation; and a third mechanism configured to receive the reoriented sheet moving in the third direction and turn the sheet to a fourth direction. The second mechanism may include, for example, a trio of elongated rollers and an endless loop belt wrapping the trio of rollers to form a nip between the belt and one of the rollers for receiving a first leading edge of the sheet in the second direction and expelling a second leading edge of the sheet in the third direction.

  • Patent number: 8200139
    Abstract: A method and apparatus for efficiently scanning a duplex document in which a scan unit sequentially scans both sides of a sheet of a duplex document by moving the sheet across a reader, and a reverse output unit to output the sheet after turning over the sheet. Therefore, since the sheet of a document can be fed and scanned while the second side of the previous sheet of the document is scanned, scanning time can be reduced. Particularly, the reduction in scanning time is very useful when multiple sheets of a duplex document need to be scanned.

  • Patent number: 8177225
    Abstract: An automatic document feeder of the present invention is provided with a turning/discharging path in a reversing path in order to read images on both sides of documents in lengths less than the main size and discharge in a discharging tray. Further, an aligning wall is provided to bump ends of documents discharged from the turning/discharging path against it. Thus, the documents of which both sides are read are discharged in the sequentially collated state at a high-speed and the aligned state.

  • Patent number: 8172225
    Abstract: A feeding device has a conveying roller that rotates in a forward direction and a reverse direction, to selectively convey a sheet in a conveying direction and a reverse conveying direction. A particular guide member is positioned on an upstream side, guides the conveyed sheet toward the conveying roller, and has a stopper that contacts an end portion of the sheet, thereby stopping movement of the sheet in the reverse conveying direction. A control unit causes the conveying roller to rotate the conveying roller in the forward direction, such that the sheet is conveyed to a predetermined position, then to rotate the conveying roller in the reverse direction, wherein the end portion of the sheet contacts the stopper while the conveying roller rotates in the reverse direction, and then to again rotate the conveying roller in the forward direction, such that the sheet is conveyed toward the conveying roller.

  • Patent number: 8167112
    Abstract: An arrangement to turn print products transported in a conveyed flow along a conveying path in a conveying direction that includes a first conveyor having a traction device guided over a reversing wheel. First clamps are attached to the traction device to clamp the respective print products. A second conveyor is arranged downstream the first conveyor includes second clamps arranged to receive the print products from the first conveyor. A curved turning section connects the first conveyor with the second conveyor along which the print products are turned upside down. The transfer device assists to transfer the print products from the first conveyor to the second conveyor and to turn the print products in the turning section prior to being clamped by the second clamps. The transfer device includes transfer tongs to turn the respective print products around an axis transverse to the conveying direction.

  • Patent number: 8141692
    Abstract: An apparatus for capturing images from checks and other financial and payment-related documents includes a base unit including an input slot for receiving a document to be processed. A transport stage located within the base unit receives the document from the input slot. The transport stage includes a document track, a processing device located along the document track, and a one-way gate located along the document track after the processing device. The document track includes a second, return path extending from a location at the one-way gate to a location before the processing device. A bi-directional drive mechanism receives the document as the document passes through the one-way gate in the forward direction. The bi-directional drive mechanism then reverses direction to drive the document in the reverse direction.

  • Patent number: 8128088
    Abstract: Disclosed is a sheet buffering and inverting device having a sheet transport path and multiple sheet inverter paths extending upward and/or downward there from. Sheets being transported through the sheet transport path are selectively diverted into the sheet inverter paths, held, and subsequently fed back into the sheet transport path such that they are inverted. Optionally, an additional sheet transport path can branch off the sheet transport path upstream of the sheet inverter paths and can connect to the distal end of each of the sheet inverter paths to allow sheets to be buffered without being inverted. This device can be incorporated into a discrete module of a modular printing system to ensure sheets are properly merged and oriented after processing by multiple printing engines. Alternatively, it can be incorporated into a standalone printing system to ensure sheets are properly buffered and/or inverted prior to processing by a single printing engine.
