【発明の詳細な説明】
本発明は時計用文字板の製造方法に関する。特
に、時分目盛、ブランド名等の表現に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a timepiece dial. In particular, it relates to expressions such as hour and minute scales and brand names.
従来、時分目盛がブランド名は印刷によるか或

鏡面状の平面にできないのでシヤープさが出な
い。後者にあつては別部材を植え込む為、最低で
も文字板上面0.2mmは針が通過できず従つて時計
全体が厚くなる。更に部品点数が多く、加工工数
もかかる為、コスト高となる。 Conventionally, the hour and minute scales were expressed by printing the brand name or by placing a diamond-cut member on the dial after press molding. However, they each have their drawbacks. In other words, in the case of the former, since it is a printing method, the surface does not have metallic luster, and even if metallic ink is used, it cannot be made into a mirror-like flat surface, so there is no sharpness. In the latter case, a separate component is implanted, so the hands cannot pass through at least 0.2mm of the top of the dial, making the entire watch thicker. Furthermore, the number of parts is large and the number of processing steps is also required, resulting in high costs.
本発明はこれら従来の文字板の欠点を解決する
ものであり、時分目盛やブランド名等が文字板上
面に突出せず、しかも平担度のあるシヤープな金
属光沢面を有した文字板を得るものである。 The present invention solves these drawbacks of conventional dial plates, and provides a dial plate that does not have hour/minute scales, brand names, etc. protruding from the top surface of the dial, and has a flat, sharp metallic luster surface. It's something you get.
本発明の要旨は特許請求の範囲に記載の通りで
ある。 The gist of the invention is as described in the claims.

に必要に応じて透明保護塗装をしてもよい。 Next, the present invention will be explained in detail with reference to Examples. First, the process of pressing out the material and welding the legs are the same as for conventional dials. The next polishing step may be a conventional buffing process, but the buffing pattern must be fine and close to a mirror surface.
In the plating step that follows, if necessary, after base plating with nickel or the like, desired finish plating with gold, silver, etc. is applied. Next, a resist film is formed by printing, photoresist method, etc. on the portion where the mirror-like plating is desired to be left. Then, using a metal brush or the like, a radial pattern called Asahiko, or parallel patterns in the vertical and horizontal directions are added and then plating is applied. In this case, it is generally preferable that the plating has a different color tone from the above-mentioned finishing plating. Then, the resist film is peeled off. Furthermore, a transparent protective coating may be applied if necessary.
上記説明中の下地メツキにおいて厚めに光沢ニ

為、表面が平滑になるので、品質が上がり、又そ
れほど高品質を望まない場合には前の工程である
研磨の品質が悪くてもいいことになり作業性や歩
留りが向上する。 When applying a thick layer of glossy nickel plating to the base plating described above, the leveling effect is strong and the surface becomes smooth, resulting in a higher quality.If you do not want such high quality, you can use the previous polishing process. It doesn't matter if the quality is poor, improving workability and yield.
なお、文字板の中心部の例えばブランド名等の
みを本発明の方法に従つてもよい。すなわち文字
板と短針の間に別部材のブランド名を植え込む隙

場合である。この場合、時分目盛は長針の先端の
なす軌跡よりも外側に配されるか、又は長針より
も低く植え込まなければならないのはもちろんで
ある。 Note that the method of the present invention may be applied only to the center part of the dial, such as the brand name. In other words, there is a case where there is no space between the dial and the hour hand to insert the brand name of a separate member, but a built-in hour and minute scale is provided. In this case, it goes without saying that the hour and minute scale must be placed outside the trajectory of the tip of the long hand, or it must be installed lower than the long hand.
以上述べたように本発明によればブランド名や
時分目盛が突出せず、しかも平担度のあるシヤー
プな金属光沢面を有した高級感ある時計用文字板
が得られる。 As described above, according to the present invention, it is possible to obtain a dial plate for a timepiece that has a high-class feel and has a flat, sharp metallic luster surface without the brand name or hour/minute scale being prominent.
