  • Sheet conveying apparatus, image scanning apparatus, and image forming apparatus
    Patent number: 7992858
    Abstract: A disclosed sheet conveying apparatus includes a first conveying unit configured to convey a sheet in a first sheet conveying direction; and a second conveying unit arranged on a downstream side of the first conveying unit in the first sheet conveying direction and configured to convey the sheet conveyed by the first conveying unit in a second sheet conveying direction different from the first sheet conveying direction. At least the second conveying unit acts as a holding/conveying unit with a holding section to hold and convey the sheet and includes a moving/guiding unit arranged along an outer side of a sheet conveying path extending between the first conveying unit and the second conveying unit. The moving/guiding unit moves/guides the sheet toward the holding section of the second conveying unit, and is arranged in a discontinuous manner along a sheet width direction orthogonal to the first sheet conveying direction so as to contact at least one part of the sheet in the sheet width direction.
