PURPOSE:To ignore a next detection data when an edge enters during operation before detecting speed by providing a circuit which detects the pulse edge for performing a proper drive control by preventing an erroneous detection which is generated when a traveling speed is fast in a drive control device. CONSTITUTION:When a pulse is generated from a waveform output part 14 in response to traveling of an actuator 13 and the edge is detected by an output waveform detection part 16, the traveling speed of the actuator 13 is detected by a speed detection part 17 in response to the edge detection. Then, a control signal determination part 11 determines the drive control signal to the actuator 13 in response to the output from the speed detection part 17 and then drives the actuator 13 through a drive part 12. When the control signal determination part 11 detects change in pulse during processing at the speed detection part 17 and the control signal determination part 11 in an output signal change detection part 18, a new decision of control signal is prohibited. |
