Title:
振動波リニアモータ及びその駆動方法
Document Type and Number:
Japanese Patent JP4276914
Kind Code:
B2
Abstract:
A vibration wave linear motor is a vibration wave linear motor that can drive a plurality of driving targets with a simple and small configuration. In the linear motor, two guide members sandwich two vibrators, which are individually and electrically connected to a driving circuit by a flexible board and an electrode connecting part, and individually driven with an independent operation. Two lens frames are individually driven by the two vibrators via a pin member, a board spring, and an engagement protruding part. For example, in a lens apparatus, one of the two lens frames holds a lens unit in the third group, which is involved in focus achievement, whereas the other lens frame holds a lens unit in the second group, which is involved in zooming.
