整膜のドット形状の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a dot shape of an illumination adjusting film formed by printing on a dial in order to equalize the brightness of the display section on the front of the dial when the indicator is illuminated. Related to the improvement of.
（従来の技術） 指示計器においては、照明時における文字板の表示部の
明度を均一化する為に文字板に照明調整膜を印刷形成す

ように多角形状の集合形状となる。This illumination adjustment film is formed by each element a of the virtual matrix on the dial surface.
The dot b is formed by a dot pattern in which the area of the dot b is changed in accordance with the shading rate required for uniforming the brightness. The shape of the dot is halftone dot printing as shown in FIG. In the case of, the dot shape is substantially circular, and in the dot generator method which is generally used, it has a polygonal aggregate shape as shown in FIG.

変化し、運転者に違和感を与える。(Problems to be Solved by the Invention) The dot shape of the illumination adjustment film is a circle or a set of minute dots, and a difference occurs in the shapes of the printed portion (dot a) and the non-printed portion. Due to the transmitted light, the shape seen through from the outside changes irregularly depending on the location of the dial, giving the driver a feeling of strangeness.
（課題を解決するための手段） 本発明は前記の課題を鑑み、ドット形状を改良したもの
である。(Means for Solving the Problems) The present invention has improved the dot shape in view of the above problems.

るものである。That is, the dot pattern of the illumination adjustment film in the indicating instrument according to the present invention is the dot pattern of the illumination adjustment film printed and formed on the dial to make the brightness of the dial uniform when the indicating instrument is illuminated. In the element formed by changing the size of the dots in the element according to the light blocking rate, each dot is formed in a rhombus shape.
（作 用） ドットを菱形状とすると、遮光率が変化しても遮光部分
と透光部分共に菱形の相似形となる。(Working) If the dots are diamond-shaped, both the light-shielding part and the light-transmitting part will be similar to the rhombus even if the light-shielding rate changes.
（実施例） 次に本発明の実施例を第１図に示した文字板におけるド
ットパターン例に基づいて説明する。(Example) Next, an example of the present invention will be described based on an example of a dot pattern on the dial shown in FIG.

（ドット）２が菱形状となり、逆に遮光率50％以上では
非遮光部分（透光部分）３が菱形状となるものである。The illumination adjusting film for the dial is formed by finely dividing the dial by virtual matrix elements 1 and printing light-shielding dots 2 having an area corresponding to a predetermined light-shielding rate on each element 1. If the shape is a regular rhombus with inner angles of 90 ° as shown in the figure, each halftone dot (dot) 2 that is a light shielding portion becomes a rhombus when the light blocking rate is 50% or less, and conversely when the light blocking rate is 50% or more. The light-shielding portion (light-transmitting portion) 3 has a diamond shape.

光部分も同様な菱形連続形状となる。In addition to the regular rhombus shape as described above, the present invention may be flat rhombic dots having inner angles of 120 ° and 60 ° as shown in FIG. In this case, when the light blocking ratio is about 30% or less, the light blocking portion (dot) 2 has a diamond shape, and when the light blocking ratio is 70% or more, the light transmitting portion has a diamond shape. Further, between 30 and 70%, both the light-shielding portion 2 and the non-light-shielding portion have the same rhombic continuous shape.

It is possible to provide a dot pattern in which the light-shielding portion and the light-transmitting portion are substantially similar to each other, and the brightness adjusting light is natural and does not cause a feeling of strangeness.
