OSCILLATING-BODY DEVICE AND OPTICAL DEFLECTOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an oscillating-body device stabilizing the oscillating movement of a needle by regulating an air flow generated by the oscillating movement of the needle and suppressing its turbulence. SOLUTION: This oscillating-body device is provided with at least one needle 101 or 102 supported to oscillate around a rotation axis 111. At least a part of the needle 101 or 102 has a semicylindrical, hemispherical or spherical air flow regulator 106. The surface of the air flow regulator 106 has a curved shape in respective cross sections perpendicular to the rotation axis 111. COPYRIGHT: (C)2009,JPO&INPIT
