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： According to an embodiment, an ADF includes: a sheet-feed cover unit; a switch unit to be switched on or off depending on whether the sheet-feed cover unit is open or closed and including a first terminal, to which a first voltage, by which a driving motor is driven, is input, and a second terminal connected to the driving motor; and an open/close-detection circuit unit that includes a first switch circuit and a second switch circuit. The first switch circuit is switched on or off based on a threshold voltage that is larger than a second voltage to be generated in the driving motor by a jammed-document removing motion and smaller than the first voltage. The open/close-detection circuit unit detects that the sheet-feed cover unit is closed when the second switch circuit is energized, but detects that the sheet-feed cover unit is open when the second switch circuit is de-energized.

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： 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.
