【産業上の利用分野】[Industrial applications]

本考案は自発光性押釦スイッチ用カバー部材、特には携帯電話機、自動車電話 機、リモコン用スイッチ、ハンディーターミナルなどの文字、記号部またはキー トップ部が自発光性である自発光性押釦スイッチ用カバー部材に関するものであ る。 The present invention is a cover member for a self-luminous push button switch, in particular, a cover for a self-luminous push button switch in which characters, symbols or key tops of mobile phones, car telephones, remote control switches, handy terminals, etc. are self-luminous. It relates to parts.

【従来の技術】[Prior art]

押釦スイッチ用カバー部材については文字、記号などが暗所でも明確に認識で きるように、カバー部材の下側にLEDなどの光源を配置し、このLEDからの 光線によって文字、記号を照光する照光式押釦スイッチ用カバー部材が公知とさ れている。 しかし、この種の照光式押釦スイッチ用カバー部材では、LEDなどの光源か らの光ですべてのキートップ部に設けられている文字、記号などを均一に照光す ることが難しく、このLEDを複数個(5〜8個)使用すると携帯電話機、リモ コン用スイッチの消費電力が増加するし、バッテリーの小型化、長時間使用が難 しくなるために、これらの電子機器の小型化、薄型化および軽量化がはかれない という不利があった。 For the push button switch cover member, a light source such as an LED is placed under the cover member so that the letters and symbols can be clearly recognized even in a dark place, and the light from this LED illuminates the letters and symbols. A cover member for a push-button switch is known. However, with this kind of illuminated push-button switch cover member, it is difficult to uniformly illuminate the characters, symbols, etc. provided on all key tops with light from a light source such as an LED. If multiple (5 to 8) devices are used, the power consumption of mobile phones and remote control switches will increase, and batteries will become smaller and it will be difficult to use them for a long time. Therefore, these electronic devices will become smaller and thinner. And there is a disadvantage that the weight cannot be reduced.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

すなわち、従来公知の照光式押釦スイッチ用カバー部材ではその文字、記号な どを明確に判断するために、LED5〜8個を光源としたものも知られているが 、これには照光ムラや輝度ムラがあり、文字、記号などのを明確に認識すること が難しいし、LEDを多数点灯するため電源の消費も大きく、したがって携帯電 話などの使用時間が短くなるという欠点があり、この欠点を解決するために押釦 スイッチ用カバー部材の下側に透明プラスチック製の導光板を設けることも検討 されているが、これには部品が増えてコストアップとなるし、小型化が難しくな るという問題点がある。 In other words, conventionally known cover members for illuminated push-button switches have 5 to 8 LEDs as the light source in order to clearly determine the letters and symbols, but this involves uneven illumination and brightness. There are irregularities, it is difficult to clearly recognize characters, symbols, etc., and a large number of LEDs are turned on, which consumes a large amount of power, and therefore has the disadvantage of shortening the usage time of mobile phones, etc. In order to solve the problem, it is considered to provide a light guide plate made of transparent plastic under the cover member for the push button switch, but this causes an increase in parts and cost, and it is difficult to reduce the size. There is a point.

【課題を解決するための手段】[Means for Solving the Problems]

本考案はこのような不利、問題点を解決した自発光性押釦スイッチ用カバー部 材に関するもので、これはゴム材料、好ましくは透明または半透明なゴム材料を 用いて成形した押釦スイッチ用カバー部材に所定の文字、記号部を自発光性材料 で印刷または成形してなることを特徴とするものであり、これはまた押釦スイッ チ用カバー部材のキートップ部の少なくとも一部を自発光性材料で成形してなる ことを特徴とするものである。 The present invention relates to a cover member for a self-luminous pushbutton switch which solves such disadvantages and problems, and it is a cover member for a pushbutton switch formed by using a rubber material, preferably a transparent or translucent rubber material. It is characterized in that predetermined characters and symbols are printed or molded with a self-luminous material, and at least a part of the key top portion of the cover member for the push button switch is self-luminous material. It is characterized by being molded by.

【0005】 すなわち、本考案者はLEDなどの光源を使用しなくても文字、記号などが暗 所でも明確に認識することができる押釦スイッチ用カバー部材を開発すべく種々 検討した結果、この押釦スイッチ用カバー部材を透明または半透明あるいは着色 ゴム材料で成形し、この押釦スイッチ用カバー部材に所定の文字、記号などを自 発光性原料で印刷するか成形すれば、これが自発光性であることからLEDなど の光源からの光線を照射しなくてもこの自発光でこの文字、記号などを容易に認 識することができるし、これについてはこのキートップ部を自発光性材料で成形 すればこのキートップ部が自発光で発光するので、このキートップ部に印刷され ている文字、記号を容易に認識できることを見出し、ここに使用する自発光性材 料の種類などについての研究を行なって本考案を完成させた。 以下にこれをさらに詳述する。That is, the present inventor made various studies to develop a cover member for a push button switch that allows characters, symbols, etc. to be clearly recognized even in the dark without using a light source such as an LED. If the switch cover is made of transparent, semi-transparent, or colored rubber material and the pushbutton switch cover is printed or molded with predetermined characters, symbols, etc. using a self-luminous material, it will be self-luminous. This character, symbol, etc. can be easily recognized by this self-luminance without irradiating the light from the light source such as LED. If this key top part is molded with a self-luminous material, We found that the characters and symbols printed on this key top can be easily recognized because this key top emits light by itself, and the self-luminous material used here was found. The present invention was completed by conducting research on the types of This will be described in more detail below.

In addition, in FIG. 1B, the key top portion 12 and the key top portion 13 are vertically stacked to form one key top portion as a whole, but this is equivalent to the key top portion 13 and the key top portion. It may be composed of the same or different self-luminous materials constituting the.

【0008】 この自発光性膜または自発光性キートップ部を有しないキートップ部2、13、 薄肉可動部3、14、ベース部4、15および導電性接点部5、16からなる押釦スイ ッチ用カバー部材は従来の方法で得られたものとすればよく、したがってこれは メチルビニルシロキサンなどのシリコーンゴム、ポリブタジエン、ポリイソプレ ン、エチレンプロピレンジエン三元共重合体、パーフルオロプロピレン・ビニリ デンフルオリド共重合体、クロロプレンゴム、ウレタンゴムなどで例示されるゴ ム系重合体と有機過酸化物とからなるゴム組成物、またはこの有機過酸化物に代 えてレドックス系触媒や硫黄、硫黄同族体などの触媒を添加したゴム組成物、あ るいはビニルシロキサンとオルガノハイドロジエンポリシロキサンおよび白金系 触媒とから付加反応型のシロキサン組成物を用いて、圧縮成形、射出成形、トラ ンスファー成形などで行えばよい。A push button switch composed of the key top portions 2 and 13 having no self-luminous film or the self-luminous key top portion, the thin movable portions 3 and 14, the base portions 4 and 15, and the conductive contact portions 5 and 16. The cover member for rubber may be obtained by a conventional method, and therefore, it may be a silicone rubber such as methyl vinyl siloxane, polybutadiene, polyisoprene, an ethylene propylene diene terpolymer, a perfluoropropylene vinylidene fluoride copolymer. A rubber composition comprising a polymer, a rubber-based polymer exemplified by chloroprene rubber, urethane rubber and the like, and an organic peroxide, or a redox catalyst, sulfur, a sulfur homologue, etc. in place of the organic peroxide. Rubber composition containing catalyst, or vinyl siloxane and organohydrogen polysiloxane and platinum catalyst Using an addition reaction-type siloxane composition from compression molding, injection molding, it may be performed in such a tiger Nsufa molding.

【0009】 しかし、この押釦スイッチ用カバー部材はシリコーンゴムからなるものとする ことが好ましいことから、これは通常は架橋したときの硬度がIRHDで80以下 であり、反撥弾性率40%以上のシリコーンゴムからなるものとするのがよい。こ れは全体を絶縁性としたもの、全体を導電性としたもの、あるいはこれらの組合 せのいずれであってもよいが通常は接点部を導電性とし、その他を絶縁性とした ものとすることがよい。However, since it is preferable that the cover member for the push button switch is made of silicone rubber, the hardness thereof when it is crosslinked is usually 80 or less in IRHD and the repulsion elastic modulus is 40% or more. It should be made of rubber. This may be either entirely insulative, electrically conductive in its entirety, or a combination thereof, but normally the contact points are electrically conductive and the others are electrically insulative. Is good.

【0010】 本考案の自発光性押釦スイッチ用カバー部材ではこの公知の押釦スイッチ用カ バー部材にキートップ部2の天面に、図1(a)に示したように自発光性膜6が 設けられるのであるが、これは押釦スイッチ用カバー部材成形時に液状の自発光 性材料をディスペンサーで注入するようにすればよい。 ここに使用される自発光性材料は透明または半透明なマトリックス部材に自発 光性部材を分散させたもので、好ましくは基本色が淡黄あるいは黄緑色で人間に 最も明るく感じる色(53nm前後の波長)で発光する蓄光顔料からなるものが好ま しく、これには燐光性硫化亜鉛/銅(ZnS:Cu)、燐光性硫化カルシウム/ ビスマス(CaS:Bi)などが例示されるが、この蓄光発光の輝度は顔料の粒 度が大きくなる程高くなるが、輝度効率や分散性、加工性からは19〜25μm程度 のものとすることが最適とされる。In the cover member for a self-luminous push button switch according to the present invention, the known cover member for a push button switch is provided with a self-luminous film 6 on the top surface of the key top portion 2 as shown in FIG. Although it is provided, the liquid self-luminous material may be injected by a dispenser when the cover member for the push button switch is molded. The self-luminous material used here is a transparent or semi-transparent matrix member in which the spontaneous light-emitting member is dispersed, and preferably has a basic color of pale yellow or yellow-green, which is the brightest color for humans (around 53 nm). (Phosphorescent zinc sulfide / copper (ZnS: Cu), phosphorescent calcium sulfide / bismuth (CaS: Bi), etc. are preferred. The higher the particle size of the pigment, the higher the brightness, but from the viewpoint of brightness efficiency, dispersibility, and workability, it is optimal to have a brightness of about 19 to 25 μm.

【0011】 自発光性材料のマトリックス材料は蓄光顔料の透過率を良くするために、でき るだけ透明度のよい材料とすることが好ましい。 また、発光した光をできるだけ高輝度のものとするには、透明度のよい材料と 蓄光顔料を配合するのであるが、蓄光顔料が少量だと輝度が低くなり、色彩もあ ざやかでなくなることが多く、蓄光顔料が大量にすぎると蓄光顔料の粒度が目だ ち、外観、デザイン上好ましくなくなるので、これらは同重量部宛配合すること がよい。The matrix material of the self-luminous material is preferably a material having as high transparency as possible in order to improve the transmittance of the phosphorescent pigment. Also, in order to make the emitted light as bright as possible, a material with good transparency is mixed with a phosphorescent pigment, but if the amount of phosphorescent pigment is small, the brightness will be low and the color will not be vivid. In many cases, if the amount of the phosphorescent pigment is too large, the particle size of the phosphorescent pigment becomes noticeable, which is not preferable in terms of appearance and design.

【0012】 また、この自発光性押釦スイッチ用カバー部材では自発光性膜6の自発光に より文字、記号などを認識するのであるが、これは外光などがあるとこの視認が 難しくなるので、これは図1(a)に示したようにこの押釦スイッチ用カバー部 材のキートップ部2、薄膜可動部3、ベース部4の外側に遮光性塗膜または着色 層7を設けて外光から遮断するようにすることがよい。 この遮光性塗膜または着色層7はシリコーンゴムなどのゴム材料に黒色、灰色 、茶色などの着色剤とこれを導電性とするための導電性付与剤としてのカーボン ブラック、ケッチェンブラックEC、金属粉末またはこれらを混合し、要すれば 電磁波シールド機能をもたせたものとすればよいが、これはカーボンブラックま たはケッチェンブラックECなどが強い遮光性および低抵抗の導電性を有するも のであることから、平均重合度が 100以上のメチルビニルポリシロキサンからな るシリコーンゴムコンパウンド 100重量部に導電性付与剤としてのケッチェンブ ラックECを35〜45重量部添加した、体積抵抗率 0.5Ωcm以下で、ウイリアムス の可塑度が 800以下、好ましくは 100〜700 のものとすればよい。The self-luminous push-button switch cover member 1 recognizes characters, symbols, etc. by the self-luminous light of the self-luminous film 6, which is difficult to see if there is external light. Therefore, as shown in FIG. 1 (a), this is provided by providing a light-shielding coating film or a coloring layer 7 on the outside of the key top portion 2, the thin film movable portion 3, and the base portion 4 of the push button switch cover member. It is better to shield from light. The light-shielding coating film or the coloring layer 7 is made of a rubber material such as silicone rubber, and coloring agents such as black, gray, and brown, and carbon black, Ketjen black EC, metal as a conductivity-imparting agent for making them conductive. Powder or a mixture of these may be used, and if necessary, an electromagnetic wave shielding function may be provided. This is because carbon black or Ketjenblack EC has strong light shielding properties and low resistance conductivity. Therefore, 35 to 45 parts by weight of Ketjenblack EC as a conductivity-imparting agent was added to 100 parts by weight of a silicone rubber compound made of methylvinylpolysiloxane having an average degree of polymerization of 100 or more, and the volume resistivity was 0.5 Ωcm or less. The plasticity of Williams may be 800 or less, preferably 100 to 700.

【0013】 なお、この自発光性押釦スイッチ用カバー部材には透光部8が設けられている が、これは遮光性塗膜または着色層7の上からレーザーマーカーからのレーザー 光をマスクを通して照射すると、このレーザー光によってこの遮光性塗膜または 着色層7が部分的に除去され、ここにマスクに刻まれている文字、記号部などの 符号が抜き文字された透光部8が形成され、図1(a)に示したような本考案の 自発光性押釦スイッチ用カバー部材が得られる。The cover member for the self-luminous push button switch is provided with a light-transmitting portion 8. The light-transmitting portion 8 or the colored layer 7 is irradiated with laser light from a laser marker through a mask. Then, the light-shielding coating film or the colored layer 7 is partially removed by the laser light, and the light-transmitting portion 8 in which characters such as characters and symbol portions engraved on the mask are omitted is formed, The cover member 1 for a self-luminous push button switch of the present invention as shown in FIG. 1 (a) is obtained.

【0014】 つぎに本考案の自発光性押釦スイッチ用カバー部材の製造方法の一例につい て述べるが、これはその各工程の縦断面図を示した図2(a)〜(f)にしたが って行なわれる。 すなわち、この自発光性押釦スイッチ用カバー部材は、まず図2(a)に示 したように着色層成形用金型21と掘り込み金型22との間に透明な未加硫のシリコ ーンゴム組成物23と加硫ずみの着色したシリコーンゴムシート24とを予め重ね、 あるいは重ねずして挿入し、熱圧して図2(b)に示したように掘り込み金型22 の上に遮光性着色層7を成形したのち、この中央凹部にシリンジ25、ディスペン サー26から液状の未硬化または未固化の自発光性材料を注入して、ここに自発光 性材料を形成させる。自発光性材料が液状でない場合には常法に従ってシートの 形態で中央凹部に挿入すればよい。自発光性材料層は硬化または固化して自発光 性膜6となる。Next, an example of a method of manufacturing the cover member 1 for a self-luminous push button switch according to the present invention will be described. This is shown in FIGS. 2 (a) to 2 (f) showing longitudinal sectional views of respective steps. Will be done. That is, as shown in FIG. 2A, the self-luminous push-button switch cover member 1 has a transparent unvulcanized silicone rubber between the colored layer molding die 21 and the engraving die 22. The composition 23 and the vulcanized colored silicone rubber sheet 24 are preliminarily overlapped with each other, or they are inserted without being overlapped with each other and heat-pressed to form a light-shielding property on the digging die 22 as shown in FIG. 2B. After molding the colored layer 7, a liquid non-hardened or unsolidified self-luminous material is injected from the syringe 25 and the dispenser 26 into the central concave portion to form the self-luminous material therein. When the self-luminous material is not in a liquid state, it may be inserted into the central recess in the form of a sheet according to a conventional method. The self-luminous material layer is cured or solidified to become the self-luminous film 6.

【0015】 ついで、図2(c)に示したようにこの掘り込み金型22と浮き出し金型27の間 にシリコーンゴム28を設置し、これを熱圧して図2(d)に示したようにこの遮 光性着色層7と自発光性膜6の上にキートップ部2、薄肉可動部3、ベース部4 、導電性接点部5を成形し、これを金型から離型したのち、図2(e)に示した ようにこの押釦スイッチ用カバー部材成形品の上に設けたレーザーマーカー29か らマスク30を介してレーザ光線を照射すると、この遮光性着色層7が部分的に除 去され、ここにマスク30に刻まれている文字、記号などが抜き文字された透光部 8が形成されて、本考案の自発光性押釦スイッチ用カバー部材が得られる。こ こで使用するシリコーンゴム28は自発光性着色層の蓄光発光の輝度を最も効率よ く効果的にするために白色とすることが好ましい。Then, as shown in FIG. 2C, a silicone rubber 28 is placed between the digging die 22 and the embossing die 27, and the silicone rubber 28 is heat-pressed as shown in FIG. 2D. Then, the key top portion 2, the thin movable portion 3, the base portion 4, and the conductive contact portion 5 are formed on the light-shielding colored layer 7 and the self-luminous film 6, and the mold is released from the mold. As shown in FIG. 2 (e), when the laser beam is irradiated from the laser marker 29 provided on the molded product of the cover member for the push button switch through the mask 30, the light shielding colored layer 7 is partially removed. Then, the light-transmitting portion 8 in which the characters, symbols and the like engraved on the mask 30 are removed is formed, and the cover member 1 for the self-luminous push button switch of the present invention is obtained. It is preferable that the silicone rubber 28 used here has a white color in order to make the luminance of the accumulated light emission of the self-luminous coloring layer most efficient and effective.

【0016】 また、図1(b)に示した本考案の自発光性押釦スイッチ用カバー部材11は、 そのキートップ部12自体を自発光性材料で成形してなるものであるが、このもの はキートップ部12が自発光するので、これは前記した図1(a)、図2に示した 自発光性押釦スイッチ用カバー部材のようにその外側に遮光性着色層7を必ず しも設ける必要はないが、設けない場合にはこのキートップ部12の天面に文字、 記号などを文字、記号部17として設けることが必要とされる。The self-luminous push-button switch cover member 11 of the present invention shown in FIG. 1B is formed by molding the key top portion 12 itself with a self-luminous material. Since the key top portion 12 emits light by itself, the light-shielding colored layer 7 must be provided on the outside of the cover member 1 for the self-luminous push button switch shown in FIGS. 1 (a) and 2 above. It is not necessary to provide it, but if not provided, it is necessary to provide characters, symbols, etc. as the character and symbol portion 17 on the top surface of the key top portion 12.

【0017】 この自発光性押釦スイッチ用カバー部材11の製造は例えばその各工程の縦断面 からなる図3(a)〜(d)に示した方法で行なわれる。 すなわち、この製造は図3(a)に示したように掘り込み金型22の中央凹部に 図2(b)と同じシリンジ25、ディスペンサー26から自発光性材料を注入などし て、ここに自発光性キートップ部12を形成したのち、図3(b)に示したように この掘り込み金型22と浮き出し金型27との間にシリコーンゴム28を設置し、これ を熱圧して図3(c)に示したようにここにキートップ部13と薄肉可動部14、ベ ース部15および導電性接点部16とからなる押釦スイッチ用カバー部材を形成させ ると同じに自発光性キートップ部と一体化させる。The self-luminous push-button switch cover member 11 is manufactured, for example, by the method shown in FIGS. 3A to 3D, which is a vertical cross section of each step. That is, in this manufacturing, as shown in FIG. 3A, the self-luminous material is injected into the central recess of the digging die 22 from the same syringe 25 and dispenser 26 as in FIG. After forming the light-emitting key top portion 12, as shown in FIG. 3 (b), a silicone rubber 28 is placed between the digging die 22 and the embossing die 27, and this is heat-pressed to apply the silicone rubber 28.
