Abstract
A driving device includes a driven mechanism to be driven by a drive signal to operate with a mechanical motion, a driver to output the drive signal, a sensor circuit to output a subject signal corresponding to a voltage that is generated by a sensor included in the driven mechanism and varies in accordance with operation of the driven mechanism, a regulator to adjust the amplitude and phase of a signal from the driver and thus generate a reference signal, and a comparator to compare the reference signal and the subject signal and output a comparison signal for detection of an anomaly in the driven mechanism.

A driving device, comprising:
- a driven mechanism to be driven by a drive signal to operate with a mechanical motion;
- a driver to output the drive signal;
- a sensor circuit to output a subject signal, the subject signal corresponding to a voltage generated by a sensor included in the driven mechanism, the voltage varying in accordance with operation of the driven mechanism;
- a regulator to adjust an amplitude and a phase of a signal from the driver, and thus generate a reference signal;
- and
- a comparator to compare the reference signal and the subject signal, and output a comparison signal for detection of an anomaly in the driven mechanism.
