摘要： 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.

摘要： An image inspecting device includes an abnormality detector and circuitry. The abnormality detector is configured to detect an abnormality of an inspection object image. The circuitry is configured to set a non-detection area to be excluded from a detection object area within which the abnormality detector detects an image abnormality and set an area including an abnormality detection portion as the non-detection area when a detection result obtained by the abnormality detector satisfies a non-detection condition.

摘要： A drive transmission device includes a rotation shaft, a drive transmitter attached to the rotation shaft to slide in an axial direction and including an engaging portion extending in the axial direction, and a coil spring to bias the drive transmitter to one side in the axial direction, and a shaft-side drive transmitter disposed on the rotation shaft. The coil spring includes a sparse portion and a dense portion. The shaft-side drive transmitter engages the engaging portion to prevent the drive transmitter from disengaging from the rotation shaft. The coil spring and the engaging portion satisfy C>A−B where A represents a length of the coil spring in a state in which the shaft-side drive transmitter retains the drive transmitter, B represents a compressed height of the coil spring, and C represents a length of the coil spring in the axial direction.
