Abstract

A radial line dial plate includes: a substrate body made of resin on which a radial line mark region is molded by a die mark-molding-face of a molding die; a plurality of fine grooves that extend radially outward in a radial direction from a center of the radial line mark region without intersecting with each other and are formed such that a distance therebetween is 1 μm or less at an outermost peripheral end to give a radial line pattern to the radial line mark region; and a metal thin film that is deposited to at least the radial line mark region of the substrate body.

First claim

What is claimed is:

1 . A radial line dial plate comprising:
a substrate body made of resin on which a radial line mark region is molded by a die mark-molding-face of a molding die; a plurality of fine grooves that extend radially outward in a radial direction from a center of the radial line mark region without intersecting with each other and are formed such that a distance therebetween is 1 I lm or less at an outermost peripheral end to give a radial line pattern to the radial line mark region; and a metal thin film that is deposited to at least the radial line mark region of the substrate body.

2 . The radial line dial plate according to claim 1 , wherein
the grooves are configured such that a depth between adjacent grooves is different.

3 . The radial line dial plate according to claim 1 , wherein
the substrate body is molded by a resin material having excellent transferability.

4 . The radial line dial plate according to claim 2 , wherein
the substrate body is molded by a resin material having excellent transferability.

5 . A radial line dial plate comprising:
a substrate body made of resin that is integrally molded by a molding die; and a metal thin film that is deposited to at least the radial line mark region provided on a surface of the substrate body, wherein the radial line mark region extends in a radial direction from a center of the substrate body and is formed into a radial line pattern shape by a large number of groove portions which are random in groove depth, respectively.

6 . The radial line dial plate according to claim 5 , wherein
the groove portions are randomly formed to have a groove depth of 1 μm as a maximum value or less.

7 . The radial line dial plate according to claim 5 , wherein
a large number of mountain portions formed between the groove portions are formed at a constant pitch.

8 . The radial line dial plate according to claim 6 , wherein
a large number of mountain portions formed between the groove portions are formed at a constant pitch.

9 . An automobile meter provided with the radial line dial plate according to claim 1 .

10 . An automobile meter provided with the radial line dial plate according to claim 2 .

11 . An automobile meter provided with the radial line dial plate according to claim 3 .

12 . An automobile meter provided with the radial line dial plate according to claim 5 .

13 . An automobile meter provided with the radial line dial plate according to claim 6 .

14 . An automobile meter provided with the radial line dial plate according to claim 7 .
