  • Patent number: 10087029
    Abstract: A sheet conveyance device includes first, second, and third rotating members and a switching unit. The first rotating member rotates in one direction. The second rotating member conveys a sheet in a first direction with the first rotating member rotating. The third rotating member conveys the sheet in a second direction, different from the first direction, in conjunction with the first rotating member rotating. The switching unit switches from a first state where the second rotating member contacts a sheet first surface and the first rotating member contacts a sheet second surface to a second state in which the first rotating member contacts the first surface of the sheet and the third rotating member contacts the sheet second surface by moving the second rotating member before a trailing edge of the sheet conveyed in the first direction is conveyed by the first rotating member and the second rotating member.
