  • Patent number: 12003678
    Abstract: An image reading device includes a reader, a transparent member, an opposing member, first and second conveyance rotators, and circuitry. The reader reads a sheet. The transparent member is disposed between the reader and the sheet. The opposing member is disposed facing the reader via the transparent member. The first conveyance rotator is disposed upstream from the reader in a conveyance direction of the sheet. The second conveyance rotator is disposed downstream from the reader in the conveyance direction. The circuitry cause the first conveyance rotator and the second conveyance rotator to convey a cleaning sheet at respective conveying speeds different from each other and bring the cleaning sheet into contact with at least one of the transparent member or the opposing member.

  • Patent number: 11126124
    Abstract: An image reading device includes a plurality of image reading units arranged at different positions in a width direction perpendicular to a conveyance direction of a recording medium to read an image on the recording medium at image reading positions and a conveyance roller pair that conveys the recording medium to the plurality of image reading units. The conveyance roller pair includes a drive roller and a driven roller that contacts the drive roller and rotates following the drive roller. The plurality of image reading units includes an upstream and a downstream image reading units downstream from the upstream image reading unit in the conveyance direction. A reading interval between the image reading positions and a diameter of the drive roller satisfy the relation: X2=n1×?×D1a, where X2 represents the reading interval, n1 represents an integer, and D1a represents the diameter of the drive roller.
