  • Patent number: 7931346
    Abstract: An electronic apparatus suppresses heat generation from a plurality of motors and a control circuit for controlling the motors without stopping operation of the motors entirely. When copy operation starts, an internal temperature of a facsimile apparatus 1 is detected. If the detected temperature is lower than a threshold value 1, an MPU section 10 instructs a motor control section 33 to operate a scanner motor 23, a CR motor 34, and a PF motor 35 at the same time. If the detected temperature is not lower than the threshold value 1 and is lower than a threshold value 2, the MPU section 10 instructs the control section 22 to operate the motors in a time-sharing mode, such that the scanner motor 23 and the CR motor 34, or alternatively, the scanner motor 23 and the PF motor 35, simultaneously operate in combination.

  • Publication number: 20090160884
    Abstract: The invention relates to an electronic apparatus in which heat generation from a plurality of motors and a control circuit for controlling the motors can be suppressed without stopping operation of the motors entirely. When copy operation starts, an internal temperature of a facsimile apparatus 1 is detected by a use temperature detecting section 17 and the detected result is then sent to an MPU section 10. If the measured temperature is lower than a threshold value 1, the MPU section 10 operates a scanner motor 23, a CR motor 34, and a PF motor 35 at the same time by use of a motor control section 33. If the measured temperature is not lower than the threshold value 1 and is lower than a threshold value 2, the MPU section 10 operates the scanner motor 23, the CR motor 34, and the PF motor 35 in a time-sharing mode by use of the motor control section 33. That is to say, the scanner motor 23 and the CR motor 34, or alternatively, the scanner motor 23 and the PF motor 35, simultaneously operate in combination.
