Abstract
A movable body apparatus includes a vibratory system, a driving portion for driving the vibratory system, a detecting portion for detecting a resonance frequency of the vibratory system, a drive controlling portion, and a storing portion. The vibratory system has a resonance frequency, and includes at least a movable body capable of being reciprocally, rotatably oscillated. The drive controlling portion regulates a driving frequency of a drive signal applied to the driving portion, based on the resonance frequency of the vibratory system. The storing portion stores the frequency detected by the detecting portion at a first predetermined time. The drive controlling portion regulates the driving frequency with reference to the stored frequency, at a second predetermined time after the storing portion stores the frequency, and executes a drive control of the vibratory system.
