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.
