Problems solved by technology

Therefore, at the time of storage or the like, there is a risk that the protrusions 261 come into contact with surrounding objects, so that some of the protrusions 261 are damaged
In addition, because some of the protrusions 261 are damaged, there is a risk that the quality of the metal texture on a part of the surface of the indicator gauge dial 121A will deteriorate.

Abstract

An indicating instrument dial plate includes a substrate that is formed in a plate shape, made of a transparent or semi-transparent material, has a front face including a hairline-treated surface and has a rear face which is irradiated with a dial plate illumination light from a light source inside an indicating instrument, and a half-mirror layer that is formed in a shape of a thin film covering the hairline-treated surface by sputtering and adapted to allow a portion of external light incident to the front face of the substrate from the outside of the indicating instrument to be transmitted into the substrate and to allow a portion of the external light to be reflected. The hairline-treated surface is made by forming fine line-shaped grooves on the front face of the substrate. The hairline-treated surface includes hairline-patterned unevenness which diffuses the external light.

Description

technical field [0001] The present invention relates to an indicating instrument dial having a surface provided with characters, scales, etc. required to indicate measured values ​​and adapted to be mounted on the indicating instrument. Background technique [0002] Figure 5 and 6 The structure of a speedometer 101 as an indicating instrument for measuring and indicating a running speed of a vehicle is shown. [0003] The speedometer 101 includes: a housing 111; an indicating instrument dial 121 attached to the front of the housing 111; a pointer 132 fixedly equipped to rotate through the indicating instrument dial 121 On the end of the pointer shaft 131 inserted in the ground; the control board 142, the control board 142 is equipped with an internal mechanism (for example, a motor) 141 for rotationally operating the pointer 132 (that is, the pointer shaft 131 ), for controlling the internal mechanism 141 A control circuit for operation, etc.; a decorative surface 151, wh...
