Abstract: In a control device, the scan control unit controls a scanning operation in which data is to be generated by reading a document. The data format selecting unit selects one of a first format or a second format different from the first format as a data format in which the data is to be generated. The resolution setting unit sets a reading resolution based on the data format. The resolution setting unit sets a first resolution as the reading resolution when the data format selecting unit selects the first format whereas the resolution setting unit sets a second resolution different from the first resolution as the reading resolution when the data format selecting unit selects the second format. The scan control unit controls the scanning operation to read the document in the reading resolution set by the resolution setting unit.

Abstract: An image reading apparatus including, a sheet feeding device, a sheet feeding section that controls transport of an original document performed by the sheet feeding device, a reading section that outputs image data by reading the original document, a carriage that is equipped with the reading section, a carriage control section that controls movement of the carriage, a buffer that temporarily stores the image data, and a monitoring section that monitors a volume of the image data stored in the buffer. When the monitoring section determines that the volume of the image data is more than a predetermined threshold value, the sheet feeding section decelerates and stops the transport of the original document, and the carriage control section accelerates the carriage in a direction opposite to the transport of the original document during a deceleration period of the transport of the original document.

Abstract: A beam light scanning device includes an image data processing unit operable to output image-processed data of neighboring pixels in such a way that the data is divided for distribution into first pixel data and second pixel data. The scanner also includes a synchronizer circuit that receives the first and second pixel data as output from the image data processor and outputs these pixel data while letting them be synchronized with clocks as synchronized based on a horizontal synchronous signal. The scanner further includes a couple of pulse width modulators or “PWMs”, a synthetic circuit, and a laser diode module. The PWMs are for adjustment of the pulse widths of the first and second pixel data as output from the synchronizer circuit respectively. The synthetic circuit combines together the pulse width-adjusted first and second pixel data. The LD emits a light beam indicative of the resultant combined pixel data.

Abstract: In a flat bed type scanner, while a control unit (24) for generating a secondary control signal and for controlling a CCD (22) is separated from an image processing ASIC (46) for generating a primary clock signal as a base signal of the secondary control signal, this scanner is arranged so as to generate the secondary control signal having the short pulse width from the primary clock signal having the long pulse width. This scanner employs such an arrangement that the primary clock signal having the long pulse width is transmitted via an FFC (40) which electrically connects the image processing ASIC (46) with the control unit (24).
