A drive device includes a piezoelectric element, a
drive shaft that receives vibration of the piezoelectric element and vibrates along an
optical axis direction of a first imaging optical
system, an engagement member that is frictionally engaged with the
drive shaft and is connected to the first imaging optical
system, and a
lens controller that controls vibration of the piezoelectric element, in which the first imaging optical
system is provided to be movable in a range including at least a first position and a second position, and the
lens controller performs control of moving the first imaging optical system from the first position to the second position in a case in which a
signal for instructing a power of the drive device to be turned off is received.
