  • Publication number: 20150014913
    Abstract: The purpose of the present invention is to provide a post-processing apparatus capable of performing conveying to and storing at a predetermined stack tray without causing sheet jamming even when a sheet having larger size than a standard size is introduced. The present invention comprises a post-processing apparatus as a processing tray on which sheets conveyed in a predetermined conveyance direction are stacked into a bundle shape, an aligning device which aligns the sheets conveyed to the processing tray, a binding device which performs a binding process on the sheets aligned by the aligning device, and a controller which controls the aligning device so that a sheet is aligned at a position being apart from the binding device by a predetermined distance when the sheet conveyed to the processing tray has a predetermined size or larger.

  • Patent number: 8636283
    Abstract: A sheet transport apparatus for transporting a sheet along a transport path has a sheet transport mechanism having a plurality of transport rollers for transporting a sheet; and a jam clearing mechanism for removing the sheet, when the sheet causes a transport failure and is jammed on the transport path. The jam clearing mechanism has a coupling member coupled to a transport roller, a jam clearing dial that transfers a rotation force to the transport roller through the coupling member, and a switching device for switching so that the coupling member separates from the transport roller in transporting a sheet, while being coupled to the transport roller in clearing a jam.

  • Patent number: 8500119
    Abstract: A sheet conveying device includes a conveying path along which a sheet is conveyed. First and second conveying roller pairs are arranged on the conveying path at a predetermined distance from each other. Overlapping conveyance sensing devices are located between the first and second conveying roller pairs and include opposing transmission device and reception device. A distance between the first and second conveying roller pairs is shorter than a length of a minimum size sheet in a conveying direction. In the conveying path between the conveying roller pairs, guide members are disposed to sandwich the transmission device and reception device. The guide members are configured to project upward or downward from a sheet conveying line by a predetermined amount with respect to the conveying path, the sheet conveying line extending through nip points of the first and second conveying roller pairs.

  • Patent number: 8422098
    Abstract: A document data capturing device includes a sheet supply tray for carrying documents, a sheet discharge tray located below the sheet supply tray, and a document conveying mechanism including a conveying path along which documents are guided from the sheet supply tray to the sheet discharge tray. The document data capturing device includes a first data-capturing unit and a second data-capturing unit which scan respective sides of a document conveyed by the document conveying mechanism. The first data-capturing unit and the second data-capturing unit are each configured with a reduction-optics scanning mechanism. The conveying path along which a document to be scanned by the first and second scanning mechanisms is conveyed is formed to surround the second reduction-optics data-capturing unit. Thus, the device can be made compact.

  • Patent number: 8210515
    Abstract: A document transport apparatus for transporting a document sheet to a predetermined position that includes a first switchback portion for switching back each of the document sheets of which the front side is read in the document reading portion to transport to the document reading portion and a second switchback portion for switching back each of the document sheets of which both sides are read in the document reading portion to discharge to the sheet discharge tray. The first switchback member provided in the first switchback portion transports two document sheets in mutually different directions and the first switchback member has a first switchback path and a first switchback roller pair each for guiding overlapping two document sheets in the mutually different directions or the same direction. The second switchback member provided in the second switchback portion transports two document sheets in mutually different directions.

  • Patent number: 7748700
    Abstract: Sheet feeding device including: a tray unit having a feeding tray for supporting a loaded-on document's trailing end, and a tilting tray for supporting its leading end; a feeding unit that feeds loaded-on documents from off the feeding and tilting trays; and an elevating mechanism that raises/lowers the tilting tray between the positions where documents are set onto and fed from it. The tilting tray is elevated by a lever that comes out of an opening in a feeding-unit cover, in which state the tray unit, which is pivotable with respect to the sheet feeding unit, is kept from pivoting. Otherwise, when the tray unit is pivoted upward from or returned to the load-on document position, tilting-tray movement, in conjunction with the pivoting action, with respect to the feeding tray is restrained.
