Abstract

PURPOSE: To produce a scale plate with a parallax preventing mirror which can be illuminated from the back face side, by providing the parallax preventing mirror dependent upon an aluminum evaporation layer on the back face of a ground plate consisting of transparent synthetic resin and printing a scale, characters, etc., on the surface.
CONSTITUTION: Aluminum evaporation processing layer 23 is formed throughout the back face side of ground plate 20 consisting of transparent synthetic resin by the aluminum evaporation processing (the first process); and next, after fan-shaped protection film 23a is provided in a part where a parallax preventing mirror should be formed (the second process), aluminum evaporation processing layer 23 in a part which is not coated with protection film 23a is melted and removed by a solvent such as a caustic soda solution (the third process). Next, printing layers 21 and 22 corresponding to a scale, an index, etc., are formed in the surface side of ground plate 20 (the fourth process), and next, the whole of the surface except a part corresponding to protection film 23a and printing layers 21 and 22 is covered with black ink 24 (the fifth process), thus obtaining the scale plate of an indicating instrument.
