CPC classification number: G02B27/0006 , B06B1/0655 , B08B7/02
Abstract: An imaging unit includes an outermost layer lens, a housing, a vibrator, a piezoelectric element, an inner layer lens, a fixing portion, an imaging element, an imaging control substrate, and a case. The vibrator vibrates the outermost layer lens held by the housing. The piezoelectric element is provided on at least one surface of the vibrator. The case is joined to the housing and houses at least the imaging element and the imaging control substrate. Wiring electrically connected to the piezoelectric element extends from an inside of the housing so as to pass a plane including a mounting surface of the imaging control substrate on which the imaging element is mounted.

Abstract: An optical device includes an outermost layer lens, a housing, a vibrator, an inner layer lens, a fixing portion, and a position adjustment portion. The vibrator vibrates the outermost layer lens held by the housing. The inner layer lens faces the outermost layer lens. The fixing portion fixes the inner layer lens to the housing. The position adjustment portion is provided in the fixing portion to adjust alignment of the inner layer lens with respect to the outermost layer lens. The fixing portion is connected to a portion of the housing that is a node of vibration by the vibrator.

Abstract: An optical device includes a protective cover, a housing, and a vibrating body that vibrates the protective cover by selecting, from multiple vibration modes in which the protective cover is vibrated, a cleaning mode in which vibration displacement of the protective cover becomes maximum and a higher-order heating mode in which the number of nodes is larger than that in the cleaning mode. In the heating mode, the position of the maximum vibration displacement in this vibration mode is within a region of the protective cover that corresponds to the field of view of the optical sensor.
