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.
Claims18
An imaging unit comprising:
- a light-transmissive body to transmit light having a predetermined wavelength;
- a housing to hold the light-transmissive body;
- a vibrator to vibrate the light-transmissive body held by the housing;
- a piezoelectric element provided on at least one surface of the vibrator;
- a lens provided at a position, in the housing, facing the light-transmissive body;
- a fixing portion to fix the lens in a portion of the housing defining and functioning as a node of vibration by the vibrator;
- an imaging element positioned such that the light-transmissive body and the lens are provided in a visual field direction of the imaging element;
- a first substrate electrically connected to the imaging element on a surface of the imaging element opposite to a surface in the visual field direction;
- and
- a case joined to the housing and in which at least the imaging element and the first substrate are housed;
- wherein
- the piezoelectric element is electrically connected to wiring extending from an inside of the housing to pass a plane including a mounting surface of the first substrate on which the imaging element is mounted.
