  • Patent number: 8488180
    Abstract: A mixture of image data in a plurality of categories is prevented from being present on one sheet of recording paper and the handling of printed recording paper is facilitated. Inputted captured image data is saved in order in an image memory. Kinds of the inputted captured image data are determined by the determination section. When the captured image data inputted to the determination section is determined to be of a different kind from the previously inputted image data, the determination section prints through a print head the captured image data previous to the captured image data determined to be of a different kind by the determination section.

  • Patent number: 5402024
    Abstract: With a view to reduce vibrations generated by a motor and improve resistance to heat, reliability and vibration isolation properties without increasing the cost or the number of manufacturing steps in a rotor for a permanent-magnet motor, a rotor core is formed of an outer peripheral portion by which the permanent magnet is fixed, and a central portion by which a shaft is fixed, a clearance is provided between the outer peripheral portion and the central portion, and the outer peripheral portion is connected to the central portion by means of a plurality of fastening members. Thus, a rotor having excellent vibration isolation properties can be obtained. Since the rotor core is formed of laminated iron plates on which the outer peripheral portion, the central portion and the fastening members are all formed as one piece, resistance to heat, reliability and the vibration isolation properties can be enhanced without increasing the cost or the number of manufacturing steps.
