Panel for indicating instrument, method of manufacturing the panel, and indicating instrument having the panel

Abstract

A panel for an indicating instrument has a base plate. The base plate has a line pattern with lines. The line pattern is defined by projections and grooves. A desired metal-like appearance is converted into a glossiness ratio Gp/Gv. The projections and grooves are formed at intervals and have at least one dimension in a direction perpendicular to the surface such that the surface has a predetermined glossiness ratio Gp/Gv. Gp is a glossiness measured in a direction parallel to an axis of at least one line. Gv is a glossiness measured in a direction perpendicular to an axis of at least one line.

1 . A method of manufacturing a panel having a line pattern defined by projections and grooves:
 converting a metal-like appearance with lines into a glossiness ratio Gp/Gv, wherein Gp is a glossiness measured in a direction parallel to an axis of at least one line and Gv is a glossiness measured in a direction perpendicular to an axis of at least one line; and   deciding an interval between the at least two adjacent projections and a dimension of the at least one projection in a direction perpendicular to a surface of the panel so that the surface of the panel has a predetermined glossiness ratio Gp/Gv.   
   
   
       2 . The method according to  claim 1 , wherein the panel is made of resin. 
   
   
       3 . The method according to  claim 1 , wherein the projections and grooves are formed by one of a die transferring using a precision die with projections and grooves, a printing using a printing plate, a hot stamping using a transferring film and a precision die, and a laminate processing.
