Abstract
A drive control device is provided that drives an ultrasonic motor element including a piezoelectric element. The drive control device includes a voltage divider circuit unit resistor forming a voltage divider circuit unit together with an identification resistor that identifies the ultrasonic motor element; a control circuit unit connected to the voltage divider circuit unit and that sets a drive condition of the ultrasonic motor element according to a voltage of an identification signal for identifying the ultrasonic motor element; and a drive circuit unit that applies a drive voltage to the piezoelectric element based on the drive condition set by the control circuit unit.
