  • Patent number: 6775418
    Abstract: An image processing device detects the correlation between a pixel to be removed in thinning pixel blocks generated by using a delay in horizontal and vertical directions and an adjacent pixel. The device then determines a coefficient corresponding to the correlation. From the pixel to be removed and the adjacent pixel, pixel data is generated by using a predetermined calculation equation. Thinning and reduction of each pixel block in the horizontal and vertical directions thus occurs.

  • Patent number: 6442028
    Abstract: An electronic device having a circuit board, a shielding plate disposed thereon and a three-terminal regulator is provided with a heat sink positioned on the outer side of the circuit board and connected to the three-terminal regulator. The heat of three-terminal regulator is radiated from the heat sink, thus making it possible to prevent heating of the shielding plate. In this way, electronic device elements that do not stand up very well to heat, such as an optical pickup unit, can be placed directly on shielding plate, so that the heat of three-terminal regulator is efficiently dissipated and the size of the electronic devices may be reduced.

  • Patent number: 5557373
    Abstract: In an image forming apparatus having a charging member for charging a photoconductive element in the form of a drum or a belt in contact therewith, a cleaning member cleans the surface of a charge roller contacting the photoconductive element. The cleaning member is usually spaced apart from the surface of the charge roller, but the former is caused to contact the latter only for a predetermined period of time at predetermined intervals. This frees the charge roller from excessive cleaning due to the cleaning member and, therefore, obviates defective images. The time for causing the cleaning member to contact the charge roller may be changed on the basis of the degree of contamination of the charge roller in order to cope with accidental smears brought about on the charge roller.
