Round scales plate with radial lines, and motor vehicle - display instrument with a round scales plate with radial lines

摘要

A round scales plate (11) with radial lines includes: a is composed of a resin (43) prepared substrate body, on which a region (53) with radial lines markings by a marking shaping surface (51) of the form of a shaping tool (49) is formed; a plurality of fine grooves (47) which are derived from a center (c) of the region (53) with radial lines markings in a radial direction, extend radially outward, without to intersect one another, and which are designed such that a distance between them on an outermost marginal edge (54) 1 μm or smaller, so that it may be a radial line pattern for the region (53) with radial lines markings; and a thin metal layer (45) which, on at least the region (53) with radial lines markings of the substrate body (43) is applied. Consequently, the round scales plate with radial lines, and the motor vehicle - display unit, which, with the round scales plate is provided with radial lines, is created which, for an observer is a look as if it passes through the cutting edges of a real metal is produced, while it is a shaped resin product and, in comparison to a metal machining product can be obtained at lower costs.
