  • Patent number: 9873577
    Abstract: In an image reading apparatus, in a first process, first and second motor rotate feed and conveyance rollers with circumferential speeds of first and second speeds, respectively. In the first process, the reverse roller has a first separation performance for separating a sheet from another sheet. In a second process, after a detector detects a leading edge of the sheet, the controller stops the first motor, and decelerates the second motor, and the reverse roller has a second separation performance lower than the first separation performance. In a third process, after a trailing edge of the sheet reaches a specific position, the first motor starts rotating the feed roller with the circumferential speed of the first speed. In a fourth process, after the trailing edge of the sheet passes through a reading end position, the controller accelerates the second motor.

  • Patent number: 8540238
    Abstract: An automatic sheet transporting apparatus includes a transporting unit with a discharge roller, the transporting unit discharge a sheet onto a discharge tray configured that support discharged sheets in a stack. A discharge guide, positioned on an upstream side of the discharge tray in a sheet discharging direction, guides a subsequent sheet transported by the transporting unit to a position between the discharge tray and a bottom surface of a previously discharged sheet in the stack. The discharge tray includes at least one rotating member that rotates when the discharge guide guides the subsequent sheet between the discharge tray and the bottom surface of the previously discharged sheet in the stack. The frictional resistance applied to the subsequent sheet is reduced to increase the number of sheets that can be stacked in the discharge tray.
