Description
제1도는 본 고안의 사용상태 사시도.1 is a perspective view of the state of use of the present invention.
제2도는 본 고안을 설명하기 위한 것으로 (a)는 키이보턴 사시도이며, (b)는 종단면 확대도.2 is for explaining the present invention (a) is a perspective view of the key button, (b) is a longitudinal cross-sectional view.
제3도의 (a)(b)는 종래 키이보턴의 설명단면도이다.(A) and (b) of FIG. 3 are explanatory sectional views of a conventional key button.
본 고안은 전화기 키이보턴의 형광표시 장치에 관한 것이다.The present invention relates to a fluorescent display device of a telephone key button.
종래 키이보턴의 상면에 표시되는 문자 또는 기호에 형광장치를 함에 있어서는 제3도(a)에 도시한 바와같이 키이보턴(1)상면에 형광도료(2)를 이용하여 표시하는 것이나 이와같은 경우 공기중의 산소와 직접 형광도료가 반응하며 퇴색하거나 키이보턴을 손가락으로 누를때마다 마모하여 변색 내지 퇴색하는 것이었다.In the case where a fluorescent device is attached to a letter or symbol displayed on the upper surface of a conventional keyboton, the fluorescent paint 2 is displayed on the upper surface of the keybottle 1 as shown in FIG. Oxygen and direct fluorescent paint reacts and fades, or wears and discolors or fades every time the key is pressed with a finger.
따라서 이를 시정하기 위해 제2도(a)에 도시한 바와같이 키이보턴(1)상면에 형광도료(2)를 이용하여 기호 또는 문자를 표시한 위에 투명의 합성수지를 입히는 것도 알려져 있으나 이 또한 외부의 광선과의 반사가 산란하며 기호 또는 문자가 선명치 못하고 또 외부 광선에 의해 형광도료가 노화되는 것이었다.Therefore, to correct this, as shown in FIG. 2 (a), it is also known to coat transparent synthetic resin on the upper surface of the key button 1 by using a fluorescent paint 2 to display a symbol or a character. The reflection of light was scattered, the sign or character was not clear, and the fluorescent paint was aged by external light.
본 고안은 상기와 같은 종래의 결점을 해결코자 한 것으로 이를 본 고안의 실시예도인 제2도(b)의 단면 설명도에 따라 설명한다. 즉 제2도(b) 도시한바와 같이 키이보턴(1)상면에는 형광도(2)가 매설홈(4)에 매설된 위에 공지의 투명합성수지(3)가 피복되는 것은 공지와 같다.The present invention is to solve the above-mentioned conventional drawbacks will be described according to the cross-sectional view of Figure 2 (b) which is an embodiment of the present invention. That is, as shown in FIG. 2B, it is known that the transparent synthetic resin 3 is coated on the upper surface of the keyboton 1 on which the fluorescence intensity 2 is embedded in the buried groove 4.
본 고안에 있어서는 상기한 공지의 키이보턴(1)의 면에 합성수지로 되고 상면(5)이 내향 만곡된 오목한 상태의 투명의 덮개(6)를 씌우고 하단(7)을 용착하면서 덮개(6)와 키이보턴(1)사이의 공간(9)에 있는 공기를 빼냄으로서 진공상태를 이루도록 하여서 된 것이다.In the present invention, the cover 6 and the cover 6 are covered with a transparent cover 6 in a concave state in which the upper surface 5 is curved inwardly and the upper surface 5 is made of synthetic resin. The vacuum in the space 9 between the key buttons 1 is achieved.
상기와 같은 구성으로된 본 고안의 작용과 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention having the above configuration as follows.
즉 키이보턴(1)을 투명의 덮개(6)로 쒸우고 그 하이의 공간(9)을 진공상태로 한 것이므로 형광도료(2)와 외기와는 완전 차단상태가 된다. 따라서 형광도료(2)는 장기간 사용함에도 불구하고 변색되거나 퇴색하는 일이 없다.That is, since the key button 1 is filled with the transparent cover 6 and the high space 9 is set in a vacuum state, the fluorescent paint 2 and the outside air are completely blocked. Therefore, the fluorescent paint 2 does not discolor or fade even after long-term use.
뿐만아니라 덮개(6)의 상면(5)을 오목한 상태로 구성했기 때문에 측면에서 키이보턴을 보더라도 글자가 똑바로 볼수있는 효과가 있다. 또 종래와 같이 형광도료상의 합성수지(3)를 누르는 것이 아니므로 마모가 거의 없이 선명하게 볼수 있는 것이다.In addition, since the upper surface 5 of the cover 6 is configured in a concave state, even if you see the key button from the side, there is an effect that the letters can be seen straight. In addition, since the synthetic resin 3 on the fluorescent paint is not pressed as in the prior art, it can be seen clearly with little wear.
따라서 제1도에 도시한 바와같이 종래의 전화기(8)의 키이보턴(1)대신 사용함으로서 야간에도 쉽게 구분할수 있는 잇점이 있는 것이다.Therefore, as shown in FIG. 1, the use of the key button 1 of the conventional telephone 8 can be easily distinguished even at night.
