Patent ID: 7986873

Claim:
An optical unit with shake correcting function comprising: a movable module on which at least an optical element is mounted; a fixed body which supports the movable module; a shake detection sensor which detects a shake of the movable module; a drive mechanism for shake correction for swinging the movable module on the fixed body on a basis of a detection result of the shake detection sensor to correct the shake of the movable module; a control section which controls the drive mechanism for shake correction on the basis of the detection result of the shake detection sensor; and a spring member which connects the movable module with the fixed body; wherein the shake detection sensor is a gyroscope which is mounted on the movable module and the control section controls the drive mechanism for shake correction so as to cancel the shake detected by the gyroscope; and when a frequency of a control signal with which the control section controls the drive mechanism for shake correction is set to be “f 1 ”, a resonance frequency of the spring member is set to be “f 2 ”, and a detuning frequency of the gyroscope is set to be “f 3 ”, and wherein the frequency “f 1 ” of the control signal, the resonance frequency “f 2 ” of the spring member, and the detuning frequency “f 3 ” of the gyroscope satisfy the following condition: f 1 <f 2 <f 3 .
