Light deflecting device
First Claim
1. An optical deflecting device comprising:
- two optical deflecting elements, each comprising a deflecting surface for deflecting a direction of light;
a first supporting member for rotatably holding a moving body, including at least the optical deflecting elements, with respect to a stationary body;
a driving mechanism for rotating the optical deflecting elements around a predetermined axis of rotation; and
a pivot which couples the moving body to the stationary body and which is disposed on a center of gravity of the moving body at a position located between the two optical deflecting elements.

Abstract
An object of the present invention is to provide an optical deflecting device capable of suppressing undesirable vibrations of an optical deflecting element such as a mirror and allowing a plurality of optical deflecting elements to be easily arranged. The optical deflecting device is characterized in that the device has: a moving body 21 having at least two optical deflecting elements 1,31 held to face each other; supporting means having a first supporting member 32 pivot-connected to the moving body 21 between the two optical deflecting elements 1,31, so as to support the moving body 21 to a stationary body 22 such that the moving body 21 is tiltable around at least a first axis; and first driving means 26, 27, 41, 43 for driving the moving body 21 around the first axis.
