Description
【発明の詳細な説明】 本発明は時計用曜車に関する。[Detailed description of the invention] The present invention relates to a day wheel for a watch.
本発明の目的は軽量で、低コストの曜車を提供すること
にある。An object of the present invention is to provide a lightweight and low-cost day wheel.
現行の曜車は、基板はアルマイト板、歯車は金属または

法で７ウトサート成形して結合する。In the current day wheel, the substrate is made of an alumite plate, and the gears are made of metal or thermoplastic resin. If the gear is metal 11
A metal gear is bonded to a fulmite plate by caulking, and if the gear is made of thermoplastic resin, it is bonded to an alumite plate by injection molding.

まい、曜車が近接の部品と接触して、止まりの原因とな
る。従って現行の曜板は変形、そりをないように作るた
めに余分な手間がかかってしまう。The problem with the above-mentioned current day wheel is that when the day wheel is incorporated into a clock, it causes the hands to stop stopping. The reason for this is that an alumite plate is used for the board, but the thickness is 7/7
Because it is very thin (100 to 10/100 isl) and has no elasticity, it tends to buckle or warp during processing, causing the day wheel to come into contact with nearby parts and cause it to stop. Therefore, it takes extra effort to make the current dayboards so that they do not deform or warp.
しかし、現行では上記のそり、！形を皆無にすること＃
′ｉｓしく、曜車は時計部品の中でも機能上不安定な部
品の一つＫなりている。However, currently the above sled,! To eliminate all form#
It is true that the day wheel is one of the most functionally unstable parts of a watch.
本発明は上記問題点を一挙に解決すると共に、低コスト
な曜車を提供することにある。The present invention aims to solve the above-mentioned problems all at once, and to provide a low-cost day wheel.

・問題点を解決すると共に、低コストの曜車を可能にし
たものである。The present invention solves the above-mentioned problems with the current day wheel by using a lightweight, flexible plastic film or paper for the substrate, and molding the gear (day star wheel) using photosensitive resin using a photographic method. At the same time, it also made possible a low-cost day wheel.

w1. It is possible to make the VC lighter than A with all the same thickness, and when the day wheel is moved, the torque of - should be about H or less compared to the current one. This is very advantageous in terms of battery life. In addition, compared to anodized aluminum plates, the amount of deformation is large under a small load, and the board is highly flexible.If the board is deformed or warped, and the main wheel is assembled into a watch, it may come in contact with a nearby piece. There is little resistance, and the chicks stop and hatch.

寄与で針る。In addition, since the current day wheel is prone to deformation and cracking, when the day wheel is incorporated into a clock, there are 207
However, since the day wheel of the present invention is light and has flexibility, it is possible to almost eliminate the space between the lines mentioned above. It will also be a contribution.
また、歯車を感光性樹脂を用いて写真法で成形すること
は、基板にプラスチックフィルムまたは紙を用いること
を可能にし、及び低コスト化につながる。Furthermore, molding the gear using a photosensitive resin using a photographic method makes it possible to use a plastic film or paper as a substrate, and leads to cost reduction.

たは紙の使用を可能にしてい石。That is, the day wheel of the present invention is produced by coating a plastic film or paper with photosensitive attenuated oil to a certain thickness, then irradiating the unexposed portion with a mask of which the gears will be formed by applying UV light. Since the @ wheel is removed on the substrate by removing it with a developer, the gear can be formed with almost no heat or distortion applied to the substrate during gear molding, making it possible to use plastic film or paper as the substrate.

を提供することが可能になる。In addition, since the gears are formed using a single-light, single-light process using a mask, there is no need for expensive molds compared to the current press method or injection molding method. It also has lighter equipment compared to presses and injection molding machines, and can be automated and continuously processed, making it possible to provide day wheels at low cost.
本発明について、実施例に基づき更に詳しく訝明すふ。The present invention will be explained in more detail based on examples.

From a functional standpoint, vapor deposition or sputtering using AtK is the most suitable stone. A thickness of 500 to 600^ for the metallized layer 2 is sufficient.

In addition to the PIT film, plastic films for the day wheel of the present invention include:
PVC and TAO films are easy to process, and if the resin has good printability, it can be re-stretched.

装、薄フィルムのラミネート法がある。As a method for metallizing paper, silver-based metallic printing and painting are simple.Next, a protective layer 3 is formed on the surface on which a is deposited. The thickness of the protective layer is preferably 10 μf1. The purpose of forming the protective layer 3 is to protect the Fikl vapor deposited layer 2. Figure 1-(2) Methods for forming the first layer 3 include spraying lacquer coating and thin film lamination.

Delicious. The purpose of forming the adhesive layer 4 is to bond the substrate and the photosensitive resin gear when forming the gear with the photosensitive resin in the first construction work. A UV adhesive is preferred as the stone adhesive layer that can be used above.

あれば使用できる。例えば、エポキシ系の接着剤がこれ
に該当する。The reason is that general KUV adhesives and photosensitive resins are highly compatible; for example, if a TJV adhesive is in a semi-cured state that is not fully cured, and a gear is formed with photosensitive resin on top of it, it will not work with the UV adhesive. This is because the photosensitive resin reacts and is bonded and adhered. In addition to the UV adhesive, any adhesive that can be used is one that is reactive with the photosensitive resin in a semi-cured state. For example, epoxy adhesives fall under this category.

させる。Next, a photosensitive resin monomer (liquid) 5 is applied to the desired thickness on the surface of the plastic film coated with the adhesive. A photosensitive resin gear 6 is formed by overlaying a mask 6 with a white spot on the target gear portion via a protective film 8 and irradiating it with UV light for an appropriate period of time. FIG. 1-(4) Next, the unfogged areas are washed off with a developer. 1st
Figure-(5) Next, the photosensitive resin and UV adhesive are sufficiently cured by post-exposure.

できることが望ましい。In terms of strength, the photosensitive resin that can be used in the day wheel of the present invention preferably has a Shore hardness of 70D or more. Further, it is desirable that the image can be developed with a neutral, weakly alkaline, or weakly acidic developer.

どなくすことが可能になっ九。When the above day wheel of the present invention was actually incorporated into a watch and a functional test was conducted, it was found that the torque was reduced to less than H compared to the conventional product, and that even if the board was deformed or warped, the board remained stable. By using a plastic film that is lighter and more flexible than conventional alumite plates, friction loss is greatly reduced, making it possible to almost eliminate clock stops caused by the day wheel.9.

を持りている。Nineteenth, the day wheel of the present invention does not have characteristics that make it possible to reduce the cost. In other words, the plastic film and paper T1 used for the substrate can be obtained at a very low cost, and the gear formation is a simple process of applying photosensitive fM#, exposing, and developing! Compared to conventional day wheels, it has very advantageous aspects in terms of cost, such as the fact that it can be made by hand, does not require expensive molds, and can be easily automated and continuously drawn.
