Abstract
When a drive command (S*) is input by a control circuit (), a drive signal (S) can be emitted to a piezoelectric actuator (Pi) by a drive circuit (), with the result that the piezoelectric actuator (Pi) is changed over from a zero position to a drive position. When a correction command (I, I) is input by the control circuit (), a correction signal (I, I) can be emitted to the piezoelectric actuator (Pi) by a correction circuit (), with the result that the piezoelectric actuator (Pi) is changed over from the zero position to a correction position. The input of the drive command (S*) and the input of the correction command (I, I) are interlocked with respect to one another.
