  • Patent number: 8190049
    Abstract: An image forming apparatus performs a single-side image formation such that, when a delay is needed, a stacked sheet discharge control section controls a sheet carrying mechanism so that: a first sheet (for a second imaging job) to be discharged after passing a first sheet-discharging roller via a first sheet-carrying path is directed to another carrying path without being discharged, and is stood by therein. The first sheet and a second sheet (for the second imaging job) which is carried to the first sheet-discharging roller via the first sheet-carrying path after the first sheet, then are concurrently discharged overlappingly. This eliminates needs for delaying image formation for the second imaging job, and for securing time for post-process for the first imaging job. Even if a delay is inevitable, this reduces the delay time greatly and improves the productivity of the image forming apparatus, without reducing its performance wastefully.

  • Patent number: 8041288
    Abstract: In a printer, a scanner unit is formed into a taper shape having a thinner thickness on a side of a pick-up roller in a removing direction of a process unit, to allow the process unit to be removed from the printer. A part of a sheet feeding path is formed in an area between the process unit and a sheet cassette. An image forming position on the sheet feed path is set lower than an upper end of the pick-up roller. Thus, removal of the process unit can be readily performed. Further, the height of the printer at a position of the pick-up roller can be reduced as compared with a case where the scanner unit is not formed into a taper shape.

  • Patent number: RE43358
    Abstract: A data reading apparatus for reading and/or scanning data from a first and second scanned medium comprising a first transportation path P1, along which the first scanned medium is conveyed and a second transportation path P2, along which the second scanned medium is conveyed and wherein the first and second transportation paths each have a common mutually shared middle transportation path through which both scanned media must pass and a common data reader reading data from each scanned medium respectively. Checks S are conveyed on the first transportation path P1, cards C are conveyed on the second transportation path P2 at a different transportation height from that of the first transportation path P1 with data read from the respective media as they are being conveyed. Because the transportation heights differ, scanned media can be transported on different transportation paths without involving special switching devices.
