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 includes: 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 first threshold value, the sheet feeding section decelerates and stops the transport of the original document, 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: An image reading device reads a document using a plurality of reading modes including a sheet-through reading mode for reading a document at a fixed reading position while the document is automatically fed. The image reading device includes a first resolution changer, a second resolution changer, and a resolution setting unit. The first resolution changer changes one of a linear velocity at which the document is fed and a traveling speed of a reading carriage to change a resolution at which the document is read in a sub-scanning direction. The second resolution changer electrically interpolates image data output from the first resolution changer to change a resolution of the image data. The resolution setting unit provides a plurality of combinations of resolution change rates between the resolution changers as resolution change modes and sets the resolution changers to one of the combinations of resolution change rates.

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.
