Title:
DRIVE DEVICE AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/156135
Kind Code:
A1
Abstract:
Provided is a drive device comprising a piezoelectric sheet (311), a movable frame (302), and a control circuit (112). The piezoelectric sheet (311) comprises a first piezoelectric body (803) that bends in a first direction, a second piezoelectric body (804) that bends in a second direction that is orthogonal to the first direction, and a connecting section (807) that connects the first and the second piezoelectric bodies (803, 804). The movable frame (302) is supported by the first piezoelectric body (803) and the second piezoelectric body. The control circuit (112) applies a voltage signal to the first piezoelectric body (803) and the second piezoelectric body, causes each of the piezoelectric bodies (803, 804) to bend, and causes the movable frame (302) to move in the first direction, the second direction, or in a combination of both directions.
