发明名称 Image reading apparatus and method for reading a document during acceleration or deceleration of a stepping motor
摘要 An image reading apparatus includes a reading device for reading a document to generate image data, and for outputting the image data at a predetermined cycle. A reading control unit receives the image data output by the reading device. A moving device, driven by a driving unit, moves the document and the reading device relative to each other. A timing control unit controls (i) a driving timing of the driving unit, and (ii) a data timing at which the image data output from the reading device is received by the reading control unit. The timing control unit controls the driving timing and the data timing such that a moving speed of the document is accelerated, and the image data output from the reading device is selectively received by the reading control unit in accordance with the driving timing.
