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.

摘要： A document reading device including an image reader. The image reader includes a first reader to read a first image from a first face of a document fed by a document feeder and a second reader to read a second face of the document. An operation mode is switchable between a normal operation mode in which the image reader is in an operation enabled state and an energy-saving mode in which the image reader is in an operation stop state. In a return from the energy saving mode to the normal operation mode, the image reader performs a start-up operation including a first initial operation for returning the first reader to the normal operation mode and then performs a second initial operation for returning the second reader to the normal operation mode.

摘要： According to an embodiment, an ADF that feeds and conveys original document sheets one sheet by one sheet from a tray unit to a read position on a document glass by motive power from a driving motor includes: an opening/closing unit operable to open and close relative to the document glass; an open/close detection sensor that detects an open/closed state of the opening/closing unit; a first interlock switch, which is arranged between a power source and the driving motor, that is on when the opening/closing unit is closed, and vice versa; and a control circuit that determines the open/closed state of the opening/closing unit based on detection outputs of the first interlock switch and the open/close detection sensor. The control circuit determines that the opening/closing unit is in the closed state when the first interlock switch is on and the open/close detection sensor is detecting the closed state.

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.
