  • Patent number: 8342505
    Abstract: An improved apparatus and method for accumulating sheets having a horizontal transport deck. Inserts are fed from an insert feeder positioned above the deck. Driven accumulator nip rollers are positioned to receive accumulations of sheets transported on the horizontal deck, and they are also positioned close enough to the insert feeder to receive inserts fed from the insert feeder. A recessed accumulation deck is positioned immediately downstream of the accumulator nip rollers. When a first sheet rests in the recessed accumulation deck, a subsequent second sheet will be placed on top of the first sheet when it enters the recessed deck. The process is controlled whereby insert sheets are released by the insert feeder prior to arrival of an accumulation on the deck. The released insert is driven by the accumulator nip rollers onto the recessed accumulator deck. Then when the accumulation arrives, it is deposited on top of the insert resting there.

  • Patent number: 8342506
    Abstract: In a sheet conveyance apparatus, a sponge roller is provided at a joining portion in which a first sheet conveyance path joins a second sheet conveyance path. A leading edge of a sheet or tailing edge of a sheet abuts at the sponge roller when the sheet is conveyed from the first conveyance path to the second conveyance path. In a projection surface in a direction orthogonal to a sheet conveyance direction in the second sheet conveyance path, an outer periphery of the sponge roller and an outer periphery of a conveyance roller, which is positioned in a downstream side, are partially overlapped in the second conveyance path. Further the sponge roller is rotatably arranged. With such a configuration, the noise generated in the joining portion can be reduced, and effect to reduce the noise can be continued.

  • Patent number: 8342500
    Abstract: An elastic sponge roller is provided at a confluence portion where a first sheet conveyance path joins in a second sheet conveyance path and a leading edge and a rear edge of a sheet are brought into contact with the sponge roller when the sheet is conveyed from the first conveyance path to the second conveyance path. Further, the sponge roller is connected to drive via a one-way clutch. Such a configuration reduces a sound produced at the confluence portion and prevents the leading edge of the sheet from being bent in colliding with the sponge roller to stabilize the conveyance of the sheet.

  • Patent number: 8335465
    Abstract: An image forming apparatus includes a first and a second image forming sections, a paper feeding section, and a paper output section. The image forming sections form an image on paper independently. The apparatus is laterally dividable into a first and a second portions where the first and second image forming sections are respectively positioned. The feeding section is arranged below the first image forming section in the first portion. The output section is arranged above the second image forming section in the second portion. The apparatus has two simple transport paths that run vertically through the image forming sections, respectively, without intersecting each other and detouring around the second or first image forming section.

  • Patent number: 8282092
    Abstract: To provide an image forming apparatus that can highly accurately position and convey, even if an inter-sheet distance of sheets to be conveyed is reduced, the sheets from registration rollers to a transfer position when a toner image on an image bearing member moving at process speed is transferred onto the sheet in the transfer position. A sheet fed from a paper feeding cassette by a pulse-motor driven paper feeding roller is conveyed to pulse-motor driven registration rollers by pulse-motor driven conveying rollers. When the sheet is conveyed to the transfer position according to restart of the registration rollers, the sheet is conveyed by the registration rollers at sheet conveying speed different from the process speed before the leading end of the sheet reaches the transfer position and is conveyed at the process speed after that.
