    Abstract: An image reader includes an image reading device, which is capable of reading a document, an initialization operation control device, which performs an initialization operation before a reading operation starts, in order to return the image reading device to a standby position where the image reading device needs to be located until the reading operation starts, an storage device that stores flag data representing whether the initialization operation needs to be performed, and a flag data control device that controls the flag data. When the flag data represents necessity of execution of the initialization operation, the initialization operation control device performs the initialization operation. When the flag data represents nonnecessity of the execution of the initialization operation, the initialization operation control device does not perform the initialization operation.

    Abstract: A digital copying device, which serves as an image reading apparatus for improving processing speed by adjusting the timing of various operations when reading is performed using a sheet-through system, causes a first traveling body to move beneath a white reference plate in order to read the white reference plate, and then performs an ADF shading operation to move the first traveling body beneath a sheet-through contact glass. The sheet-through contact glass is then subjected to a dirt detection operation by reading a dirt detection reference plate, whereupon an original is conveyed onto the sheet-through contact glass by an ADF to perform a sheet-through reading operation whereby an image of the original is read. When a sheet-through reading operation is to be performed, the sheet-through reading operation is started following the reception of an image reading request and after the elapse of a time (T=Ts+Tl−Td) obtained by subtracting a time Td, which extends from the beginning of the sheet-through reading operation to the point at which the tip of the original reaches a sheet-through reading position, from the sum of a time Ts required for the ADF shading operation and a time Tl required for the dirt detection operation.

    Abstract: A sheet-fed scanner capable of scanning multiple scan lines for image signal calibration includes a housing, a sheet-feeding mechanism, a first scanning module, a first actuator and a first calibration sheet. The sheet-feeding mechanism disposed in the housing feeds a document across a scan region. The first scanning module rotatably mounted in the housing scans a front side of the document fed across the scan region. The first calibration sheet is fixed in the housing and disposed in the scan region. The first actuator drives the first scanning module to rotate such that the first scanning module senses a plurality of scan lines on the first calibration sheet to obtain a first calibration standard for calibrating a first image signal of the front side of the document. Thus, it is possible to avert any flaws in image quality caused by the contaminated calibration sheet.

    Abstract: The image reader according to the present invention is able to set the accurate threshold level free of influence of dirt and dust even when the reference “white” level is requested for shading correction during the acceleration while the carriage is being accelerated without increasing the averaging frequency when the reflected light from the white board is read for shading correction. In addition, because the distance between the head end of the transparent glass and the home position as well as the distance between the home position and the reading window are shortened, the size of the image reader is reduced.
