Document Type and Number:
WIPO Patent Application WO/2006/009216
Kind Code:
A1
Abstract:
A light pressure rotator being light-pressure-trapped by irradiation with light and provided with a plurality of blades on the side of light pressure rotation about the central axis of rotation. The light pressure rotator (1) being light-pressure-trapped by irradiation with light and light-pressure-rotating about the central axis O of rotation, characterized in that a reverse torque generating section generating a torque for rotating the rotator in the direction reverse to the predetermined direction is removed from a section arranged with three blades each having a first side face (3) extending in the radial direction from the central axis O of rotation, a second side face (4) facing the central axis O of rotation, a third side face (5) facing the first side face (3), a lower surface (6) intersecting the central axis O of rotation, and an upper surface (7) facing the lower surface (6). The light pressure rotating device characterized by comprising the light pressure rotator (1), a light source C, and an objective (condenser) lens D.
