Abstract

An operating apparatus (1) of the present invention has a driven element (5), a frame (4) having a contacted element (51) and rotatably supporting the driven element (5), and an ultrasonic motor. The ultrasonic motor includes a vibrating element (6). The vibrating element (6) includes a first piezoelectric element (62) that undergoes extension and contraction by application of an AC voltage, a reinforcing plate (63) having a contact portion (66) and an arm portion (68), and a second piezoelectric element (64) that undergoes extension and contraction by application of an AC voltage. The first piezoelectric element (62), the reinforcing plate (63), and the second piezoelectric element (64) are laminated in this order. The vibrating element (6) is fixedly mounted on the driven element (5) in a state where the contact portion (66) abuts on the contacted element (51). Further, the vibrating element (6) receives reaction force from the contacted element (51) when the vibrating element (6) vibrates so that the driven element (5) is rotated together with the vibrating element (6) by means of the reaction force.

Description

technical field [0001] The invention relates to operating devices and electronic instruments. Background technique [0002] Hitherto, an operating device for driving a driven element of a pan-tilt-type zoom camera or the like is well known. In such an ultrasonic motor, as the above-mentioned technique, a technique described in a website (URL: http: / / www.viewmedia.co.jp / kiki / vcc4.htm (Japanese only)) is known. [0003] However, in the conventional operating device, since the driving mechanism of the driven member is constituted by a large motor such as an electromagnetic motor, there has been a problem that the entire apparatus becomes large in size. Contents of the invention [0004] An object of the present invention is to provide an operating device and an electronic instrument which can minimize the size of the entire equipment. [0005] In order to achieve the above object, in one aspect of the present invention, the present invention is directed to an operating devi...
