摘要:
A diffusing plate having a smooth rough surface is obtained by recording on a photosensitive material the image of a mask having a regular fine pattern thereon, treating the photosensitive material to thereby obtain a photosensitive material having smooth roughness, transferring the smooth roughness of the treated photosensitive material to a metal mold, and embossing plastics on the metal mold.

The tiltable-body apparatus including a frame member, a tiltable body, and a pair of torsion springs having a twisting longitudinal axis. The torsion springs are disposed along the twisting longitudinal axis opposingly with the tiltable body being interposed, support the tiltable body flexibly and rotatably about the twisting longitudinal axis relative to the frame member, and include a plurality of planar portions, compliant directions of which intersect each other when viewed along a direction of the twisting longitudinal axis. A center of gravity of the tiltable body is positioned on the twisting longitudinal axis of the torsion springs.
