【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は電子機器等に使用される照光式キートップにおける操作ボタン部の構造に関する。 The present invention relates to a structure of the operation button unit in the illumination type key top that is used in electronic equipment and the like.

【0002】 [0002]

【従来の技術】従来この種の操作ボタンの構造において、文字照光方式のプラスチック製キートップにする場合の構造を図2に示す。 BACKGROUND OF THE INVENTION structure of a conventional operation button of this kind, showing the structure in the case of the plastic key top of a character illumination type in Figure 2. この構造はキートップ21,キーシート22,フロントカバー23,導光板14,キースイッチ15,光源(LED)16およびサポート板1 This structure keytop 21, the key sheet 22, the front cover 23, the light guide plate 14, the key switch 15, a light source (LED) 16 and the support plate 1
7とから構成される。 It consists of 7. キートップ21は裏面に凹部21 Recess key top 21 to the rear face 21
aと側面にフランジ部21bを有する形状になっており、キーシート22は表面および裏面にそれぞれ凸部2 The a and the side surface is a shape having a flange portion 21b, the key sheet 22, respectively on the front surface and the back surface protrusions 2
2a,22bを有する形状となっている。 2a, it has a shape having a 22b. キートップ2 The key top 2
1の裏面凹部21aとキーシート22の表面凸部22a Surface protrusion 22a of the first back side recess 21a and the key sheet 22
が嵌合し、かつキートップ21のフランジ部21bがフロントカバー23の裏面に突き当たり、かつキートップ21の裏面凸部22bがキースイッチ15の接点部を押すことになり、キートップ21は位置決めされて脱落しない構造となっている。 There fitted, and a flange portion 21b of the key top 21 abuts against the rear surface of the front cover 23, and the back surface convex portion 22b of the key top 21 is turned to push the contact portion of the key switch 15, the key top 21 is positioned and it has a structure that does not fall off Te.

【0003】さらに、キートップ21に表示される文字部のみが照明される方式、すなわち文字照光方式にするために、キートップ21をプラスチックの2色成形等で成形することにより、文字部のみ光が透過することになる。 [0003] Further, the method of only character portion displayed on the key top 21 is illuminated, ie, to the character Lighting method, by molding a key top 21 by two-color molding of plastic, only the character portion optical There will be transparent. キーシート22はシリコンゴム成形することにより光透過性となっている。 Key sheet 22 has a light transmitting property by silicone rubber molding. 従って光源(LED)16から発生られた光は、透明プラスチック等で成形された導光板14,キーシート22,キートップ21の順に透過し、キートップ21の表面においては文字部のみ光って見えることになり、文字照光式のプラスチック製キートップが得られる。 Thus the light source light is generated from the (LED) 16 is a transparent plastic light guide panel formed in such 14, the key sheet 22, and transmitted in the order of the key top 21, in the surface of the key top 21 that appear to glow only character portion now, the plastic key top of the character illuminated can be obtained. なお、フロントカバー23は遮光性の材料を用いている。 Incidentally, the front cover 23 is using a light-blocking material.

【0004】 [0004]

【発明が解決しようとする課題】上述した従来のキートップ構造には、以下のごとき問題点がある。 The object of the invention is to be Solved by the conventional key top structure described above, there is a following of such problems.

【0005】(1)キートップの形状において、凹部やフランジ部等が必要であり、薄型化及び低コスト化が難しいこと。 [0005] (1) In the key top shape, it is necessary to recess and flange portions, etc., that thin and cost is difficult.

【0006】(2)文字部のみ光を透過するプラスチック製キートップを成形する方法として、2色成形や転写成形を行うとコスト高となる。 [0006] (2) As a method of molding a plastic key top which transmits character portion only light, comes to perform two-color molding or transfer molding cost.

【0007】(3)上記(2)の欠点を避けるために、 [0007] (3) In order to avoid the disadvantages of the above-mentioned (2),
表面を塗装や印刷した後にレーザ光線で文字部のみ剥ぎ取る工法も行なわれているが、表面からの処理であるため耐磨耗性が良くないこと及び文字部に使用できる色調の制約が多い等の欠点がある。 Have been also performed method peeling laser beam only character portion after the painting or printing surface, the color of constraints that can be used in and the character portion abrasion resistance is poor because of the processing from the surface is large, etc. there is a drawback.

【0008】 [0008]

【課題を解決するための手段】本発明の照光式キートップの構造は、キートップの押下によりキーシートを介してキースイッチの接点部を押し内部の光源が光を発する照光式キートップにおいて、前記キートップは光透過性を有するプラスチックからなり、また前記キーシートは光透過性を有する弾性体からなり、且つ前記キートップと前記キーシートを接着等により一体化してなり、また前記キートップの裏面から文字部のみ光が透過するように表示文字等を印刷し、且つ前記キーシートの前記キートップとの接着面以外の部分を遮光処理してもよい。 Structure of the illumination type key top of the present invention SUMMARY OF], in illumination type key top inside the light source emits light press contact portion of the key switch via the key sheet by pressing the key top, the key top is made of plastic having a light transmission property and the key sheet is made of an elastic material having optical transparency, and it and the key top and the key sheet integrated by bonding or the like, also of the key top print the display character or the like as the light only a character portion from the back side is transmitted, and may be shading the portions other than the bonding surface between the key top of the key sheet.

【0009】 [0009]

【実施例】次に本発明について図面を参照して説明する。 EXAMPLES The present invention will be described below with reference to the drawings.

【0010】図1は本発明の一実施例を示す断面図である。 [0010] Figure 1 is a sectional view showing an embodiment of the present invention.

【0011】本実施例は透光性のプラスチックからなるキートップ11,このキートップ11の直下にあり透光性のシリコンゴム成形品からなるキーシート12,遮光性の材料からなりキーシート12を押えつけるフロントカバー13,透明プラスチック等で成形された導光板1 [0011] This example key top 11 made of transparent plastic, the key sheet 12 has consisting translucent silicone rubber molded article directly under the key top 11, the key sheet 12 made of a light shielding material holding down the front cover 13, it has been light guide plate 1 molded in a transparent plastic or the like
4,キーシート12の下部に接するキースイッチ15, 4, the key switch 15 in contact with the lower portion of the key sheet 12,
導光板14内に設けられた光源(LED)16およびこれらを搭載するサポート板17から構成されており、キートップ11を押下することによりキーシート12を介してキースイッチ15の接点部を押し、光源16が光を発するようになっている。 A light source provided on the light guide plate 14 is composed of a support plate 17 for mounting (LED) 16 and these, press contact portion of the key switch 15 via the key sheet 12 by pressing the key top 11, light source 16 is made to emit light. ここでそれぞれ平面状をなすキートップ11の裏面と、キーシート12の表面の相対する面とを接着し、キートップ11とキーシート12を一体化する。 Here adhered with the back surface of the key top 11 forming a planar, respectively, and opposing surfaces of the surface of the key sheet 12, to integrate the key top 11 and the key sheet 12. しかる後に、下方からサポート板17、キースイッチ15、導光板14、キーシート12、キートップ11、フロントカバー13の順になるように順次重ね合わせることにより全体が構成される。 Thereafter, the support plate 17 from below, the key switch 15, the light guide plate 14, the key sheet 12, the key top 11, the entire By sequentially superimposed so that the order of the front cover 13 is constructed. キーシート1 The key sheet 1
2との接着により、キートップ11の形状を非常に単純化することができる。 The adhesion of the two, the shape of the key top 11 can be very simplified.

【0012】さらに文字照光方式のキートップとする場合は、キートップ11を透光性のプラスチックで成形した後に、キートップ11の裏面に遮光色のインクで抜き文字印刷を施せば良い。 [0012] Further, when the key top character lighting method, after molding the key top 11 of a translucent plastic, may be subjected to outline character printing ink of light-shielding color on the back surface of the key top 11. また照光文字に色を付与したい場合は、その上から透光色のインクでべた印刷すれば良い。 Also if you want to impart color to the lighting characters may be printed solid ink translucent colors thereon. なおキーシート12は従来と同様に透光性のシリコンゴム成形品を用い、キートップ11との接着面以外の部分は塗装または印刷等の方法により遮光処理するものとする。 Note the key sheet 12 using conventional as well as translucent silicone rubber molded article, portions other than the bonding surface of the key top 11 is assumed to shading by a method such as coating or printing.

【0013】従って、光源16から発せられた光は、透明プラスチック等で成形さてた導光板24、キーシート12、キートップ11の順に透過し、キートップ11の表面においては文字部のみが光って見えることになり、 [0013] Therefore, the light emitted from the light source 16, a light guide plate 24 was molded from a transparent plastic or the like, the key sheet 12, and transmitted in the order of the key top 11, in the surface of the key top 11 glowing only character portion It will be visible,
文字照光式プラスチック製キートップが得られる。 Character illuminated plastic key top is obtained.

【0014】 [0014]

【発明の効果】以上説明したように本発明によれば、以下の様な効果が得られる。 According to the present invention as described in the foregoing, the following such effects.

【0015】(1)キートップの形状が単純化でき、薄型化及び低コスト化が可能となる。 [0015] (1) can be simplified the shape of the key top, and thin and low cost.

【0016】(2)キートップの裏面に表示文字を印刷するため、文字消え等の耐磨耗性による不具合の心配がない。 [0016] (2) In order to print the display characters on the back of the key top, there is no worry of the problems caused by wear resistance, such as disappear character.

【0017】(3)透光色であれば、透光文字色の色調は自由に選べる。 [0017] (3) if it is translucent color, translucent character color of the tone choose freely.
