摘要： The present invention discloses code plate of an optical encoder having a planar portion that is located on a surface to which a light flux for detection is applied; and a non-planar portion that is arranged alternatively with the planar portion on the surface and is comprised of multiple convex structures and concave structures arranged continuously intersecting to a parallel direction of arranging the planar portion and the non-planar portion. The longitudinal direction in the planar portion and the non-planar portion is consistent with the radial direction of the code plate, and a direction (Parallel direction) in which the planar portion and the non-planar portion are arranged alternately is consistent with the circumferential direction of the code plate. The non-planar portion which forms the concave and convex structure is formed by arranging multiple V-shaped structures in the longitudinal direction of the non-planar portion. Since the multiple V-shaped structures are arranged in the direction in which the non-planar portion is extending, the width of the V-shaped structure is not restricted by the width of the non-planar portion in the parallel direction.

摘要： A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion which consists essentially of a single material and which includes a first surface having a smooth surface portion, and a second surface having plural convex portions. Each of the plural convex portions includes a first inclined surface having a concavo-convex portion thereon; and a second inclined surface having a smooth surface portion. The concavo-convex portion allows at least part of light incident from the first surface to cause total reflection, diffraction and interference and to travel toward the smooth surface portion of the second inclined surface, and the smooth surface portion selectively reflects visible light in a predetermined wavelength range toward the first surface, so that when the first surface of the resin molding is observed from outside, the resin molding has a colored appearance with at least one color in addition to a metallic appearance.

摘要： A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion, which has a first surface having a smooth surface portion, and a second surface having plural sections, wherein each of the plural sections has a width and includes one or more convex portions which have one or more ridge lines extending in a ridge line direction. The ridge line direction of the one or more convex portions of at least one of the plural sections is different from the ridge line direction of the one or more convex portions of one or more of others of the plural sections. When the first surface of the resin molding is observed from outside, the resin molding has metallic appearance.
