<p><P>PROBLEM TO BE SOLVED: To provide a drive controller that can start an operating apparatus after passage of a specified time since outputting a trigger signal while starting a step-up circuit only when there is a necessity to operate the operating apparatus. <P>SOLUTION: In the drive controller 5, the trigger signal output from CPU24 is input into both a specified voltage generating circuit 12 and a signal delay part 25. Then, the signal delay part 25 generates a motor starting signal by delaying the input trigger signal for a set time and outputs the motor starting signal into a drive signal generator 13. Then, the drive signal generator 13 outputs a high level of drive signal, if a motor control signal is high-level, and drives a motor 34 thereby, since power supply at a specified voltage is performed from the specified voltage generating circuit 12 and also a motor control signal with its pulse width at its initial value is input when the high level of motor starting signal is input. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
