PURPOSE: To control a fan motor with the optimum driving power without consuming the unnecessary current, by controlling the fan motor for an image forming device and the fan motor for the both side unit in a state of high sped rotation, low speed rotation and stopping respectively corresponding to the specified conditions for instance, such as the standby, the single side successive print and the both side successive print. CONSTITUTION: The speed of the fan motor for the image forming device and fan motor for the both side unit device are controlled corresponding to the respective states such as the standby, the single side successive print, the both side successive print. The rotary speed of fan motor is controlled in three ways by the output signal form the two ports A and B by the control part 100 of the both side unit device and the image forming device. The control part 100 controls the entire operations of the both side unit and the image forming device, is provided with the CPU, the memory such as the ROM for storing the control procedure by the CPU, the memory such as the RAM furnished with the operation area for the CPU and the nonvolatile memory. |
