  • Patent number: 10173855
    Abstract: A sheet conveyance apparatus comprises a first sheet accommodation unit, a second sheet accommodation unit, a conveyance path and a controller. The first sheet accommodation unit and the second sheet accommodation unit are both provided with a movable guide plate which determines the size of an accommodated sheet. The conveyance path conveys a sheet between the first sheet accommodation unit and the second sheet accommodation unit. The controller carries out a control processing so as to change, in a case in which the accommodation size of the first sheet accommodation unit is changed, the accommodation size of the second sheet accommodation unit to be the same as that of the first sheet accommodation unit.

  • Patent number: 10099883
    Abstract: An apparatus is provided that may offer functionalities including printing, scanning and/or copying. The apparatus may include a manual sheet feeding tray disposed at the rear of the apparatus. The height of the sheet feeding tray might not exceed a height of the apparatus, allowing use of the apparatus in spaces having smaller depths. The apparatus may include a sheet guide configured to move in conjunction with the movement of the tray. In some arrangements, a surface of the sheet feeding tray may differ in height between lateral edges of the tray and a central portion. This difference may cause a sheet to be curved in a lateral direction, rendering the sheet more inflexible in a longitudinal direction. According to other aspects, a depressed portion of the tray may match a protrusion extending from the guide in shape such that the two portions may mate in a retracted position.

  • Patent number: 10053323
    Abstract: A sheet handling apparatus for a printing system includes a rotary drum having an inner chamber circumferentially surrounded by an outer peripheral wall with perforations formed therein. By means of sucking an air flow through the perforations of the drum to a suction system, sheets are attracted to the peripheral wall of the drum. A stationary shutter member is positioned inside the inner chamber for blocking the flow of air through the perforations when they pass, with the rotation of the drum, through a first predetermined angular range. The shutter member includes protrusions while the rotary drum includes recesses for receiving the protrusions, such that a meandering air flow passage is formed between the shutter member and the rotary drum. As such, friction between the rotary drum and the stationary shutter member is reduced, thereby reducing the power consumption of the suction system.

  • Patent number: 10042304
    Abstract: A sheet conveyance apparatus according to an embodiment includes a conveyance roller and a register roller arranged downstream of the conveyance roller along a sheet conveyance path. A sensor unit detects a first deflection amount of the sheet and a second deflection amount of the sheet when the sheet is pressed against the register roller. A movable section is connected to at least one end of the conveyance roller. A control section determines a tilt of a rotation axis of the conveyance roller relative to a rotation axis of the register roller based on a difference in the first and second deflection amounts detected by the sensor unit. The control section controls the movable section to move the conveyance roller so that the rotational axis of the conveyance roller is positioned relative to a rotational axis of the register roller in accordance with the determined tilt.
