摘要： A sheet conveyance device includes a loading section, a sheet feeding unit, a separation section disposed downstream in a sheet conveyance direction from the sheet feeding unit, a conveyance member to transport a sheet separated by the separation section, a trailing-edge detector disposed at a first conveyance distance (L1) downstream from a separation position (Ab) and including a rotary follower and a rotation detector, a first leading-edge detector disposed downstream from the trailing-edge detector, and a controller. The trailing-edge detector A detects a sheet length in the sheet conveyance direction. The controller causes the sheet feeding unit to start sheet feeding in response to detection of the leading edge of the sheet by the first leading-edge detector when the detected sheet length equals a predetermined reference length and in other cases in response to detection of the trailing edge of the sheet by the trailing-edge detector.

摘要： In an image reader, a reading member fixedly mounted in the image reader reads an image on a sheet conveyed into the image reader. A guide is disposed opposite the reading member to support the sheet with respect to the reading member. A guide moving member moves the guide with respect to the reading member in a main scanning direction in which the reading member reads the image on the sheet. A guide rotating member rotates the guide in a sub-scanning direction perpendicular to the main scanning direction. A controller controls the reading member to scan different positions on the guide moved by the guide moving member and rotated by the guide rotating member to generate shading data.

摘要： An image reading device and an image forming apparatus. The image reading device includes an image reader to read an image of a document, and a color reference component arranged to face the image reader. In the image reading device, the image reader reads the color reference component at a prescribed timing to obtain color reference image data, and correction data generating processes are executed based on the obtained color reference image data to generate correction data used to correct data of the image read by the image reader. In the image reading device, wherein the color reference component is moved relative to the image reader in a direction orthogonal to a direction toward and away from the image reader. The image forming apparatus includes the image reading device, and an image is formed on a recording material based on data of the image read by the image reading device.
