【発明の詳細な説明】 （産業上の利用分野） 本発明は指示計器の照明時における文字板前面の表示部
の明度を均一化する為に文字板に印刷形成される照明調
整膜のドットパターン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 pattern 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 during illumination of the indicating instrument. Related to the improvement of.

る。(Problems to be Solved by the Related Art and Invention) In an indicating instrument, it is necessary to print and form an illumination adjusting film on the dial in order to equalize the brightness of the display portion of the dial during illumination. It is disclosed in Japanese Patent No. 2065.

想マトリクスの各要素ａの面積に対応して必要な遮光率
の面積とした１個のドットｂを設けてなるものである。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 size of the dot b is changed according to the light blocking ratio required for uniforming the brightness. For example, as shown in FIG. 2, one dot b having an area of a required light blocking rate corresponding to the area of each element a of the virtual matrix is provided.
しかし、ドットパターンの全体をポジにより形成すると
遮光率の大きいところではドットｂが大きくなってしま
い、照明時にドットｂが文字板前面から透視されてしま
うことがある。However, if the entire dot pattern is formed positively, the dot b becomes large in a place where the light blocking rate is large, and the dot b may be seen through from the front surface of the dial during illumination.

転せしめてなることを特徴とするものである。(Means for Solving the Problems) In view of the problems described above, the present invention is to prevent the dots in the light-transmitting portion from becoming larger than a predetermined size. 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. What is formed by changing the size of the dots in the element according to the light blocking rate is that the positive / negative of the dots is inverted with a predetermined light blocking rate as a boundary.
（作 用） ドットパターン全体をポジで形成せず、所定の遮光率以
上をポジネガが反転させると、遮光部分が独立した点と
ならないため、透視されることはない。(Working) If the positive dot is not formed over the entire dot pattern and the positive negative is reversed at a predetermined light shielding rate or more, the light shielding portions are not independent points, and thus are not seen through.
（実施例） 次に本発明の実施例を図面に基づいて説明する。(Example) Next, the Example of this invention is described based on drawing.
ドットパターンは第１図に示すように文字板面の仮想マ

１内に遮光部分のドット２をポジとして形成する場合、
遮光率が例えば50％以下では従前と同様で、50％以上と
なるとドット２′をネガとし、ドット２′以外の部分３
に遮光印刷を施すものである。In the dot pattern, as shown in FIG. 1, when each element of the virtual matrix on the dial plate is formed as a single area 1 and the dots 2 of the light-shielded portion are formed as positive in this unit area 1,
If the light blocking rate is, for example, 50% or less, it is the same as before, and if it is 50% or more, the dot 2'is made negative, and the portion 3 other than the dot 2'is
The light-shielding printing is applied to the.
従って、遮光率50％のときの円形のドットは、単位エリ

ては最大の半径0.5mm（単位エリアの一方を１mmとした
と仮定したとき）ドット（遮光率80％相当）に比して半
径が20％も少なくなったものである。Therefore, the radius of the circular dot when the shading rate is 50% is 0.4 mm when one side of the unit area 1 is 1 mm. This is the largest dot, and the radius is 0.5% (assuming one of the unit areas is 1 mm), which is the largest radius of a single circular dot in the past. Is also less.

前後が適当である。Physical theory The present invention is not limited to positive / negative reversal of dots at a light blocking rate of 50%, and the light blocking rate may be set appropriately for reversing, but if the light blocking rate for reversing is increased, the dots become larger accordingly. If the light-shielding rate is small when inverted, the light-transmitting part will be visible as a circle, so 50%
The front and back are appropriate.

る。(Effects of the Invention) In the present invention, when the illumination adjusting film on the dial of the indicating instrument is printed as described above, the light blocking rate is adjusted by the dot area, and the positive / negative of the dot is reversed at a predetermined light blocking rate. Therefore, the dot portion is prevented from becoming large so that it is difficult to visually recognize the dot portion from the outside.
