본 고안은 텔레비젼 수상기의 선국장치에 사용되는 전자튜닝 유니트에 있어서 선국된 채널을 조사(照射)하여 표시하는 채널표시 장치에 관한 것이다.The present invention relates to a channel display device for irradiating and displaying a channel tuned in an electronic tuning unit used in a television receiver tuning device.
종래 일반적인 전자튜닝 유니트에 있어서는 선국하고져 하는 채널의 푸쉬버튼을 누르면 푸쉬버튼에 의해 작동되는 스위치 접점이 온(ON)으로 되고 동조회로부와 당해 채널의 동조코일이 접속되어 선국됨과 동시에 조작 패널부의 반투명 재질로 된 표시판에 인자된 당해 채널표시기호(숫자)를 내부로부터 조사하는 램프 또는 발광다이오드가 점등되어 선국된 채널을 표시하게 되는 것이다.In the conventional general electronic tuning unit, when the push button of a channel to be tuned is pressed, the switch contact operated by the push button is turned on, and the tuning circuit section and the tuning coil of the channel are connected and tuned, and at the same time, the translucent material of the operation panel section is selected. The lamp or light emitting diode that irradiates the channel display symbol (number) printed on the display panel from the inside is turned on to display the selected channel.
그러나 상기 램프 또는 발광다이오드는 각 채널마다 하나씩 설치해야 하므로 각 램프 또는 발광다이오드의 배선접속에 따라 구조가 복잡하게 될 뿐 아니라 제조원가가 상승되는 폐단이 있었다. 따라서 본 고안은 이러한 종래의 폐단을 해소하고 하나의 램프로써 다수의 채널을 표시할 수 있도록 하려는 것으로 이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.However, since the lamp or the light emitting diode should be installed one by one for each channel, not only the structure becomes complicated according to the wiring connection of each lamp or the light emitting diode but also the manufacturing cost is increased. Therefore, the present invention is intended to solve such a conventional closure and to be able to display a plurality of channels with a single lamp as described in detail according to the accompanying drawings as follows.
도시한 바와 같이, 다수의 선국용 푸쉬버튼(2)이 설치된 튜닝유니트 본체(1)의 하부에는 다수의 광전송용 분지편(4)을 보유하는 원통형 분광체(3)내에 램프(5)를 설치하고, 각 분지편(4)의 선단에 형성된 전광절곡부(6)와 이격 대향하는 수광절곡부(8)를 보유하는 광전송용 연결용(7)을 각 푸쉬버튼(2) 끝단 측으로 연장 설치하며, 상기 푸쉬버튼(2)에는 전광절곡부(6)와 수광절곡부(8) 사이의 간극에서 접동하여 차광하는 차광판(9)을 일체로 형성하고, 차광판(9)에는 선국시 절곡부(6)(8)를 광학적으로 연통시키는 통공(10)을 천설한 것이다.As shown in the figure, a lamp 5 is provided in a cylindrical spectrometer 3 having a plurality of light transmission branch pieces 4 below the tuning unit main body 1 provided with a plurality of tuning pushbuttons 2. And an optical transmission connection (7) having an all-optical bending portion (6) formed at the tip of each branch piece (4) and facing the light receiving bending portion (8) spaced apart from each other. In addition, the push button 2 is integrally formed with a light shielding plate 9 sliding and shielding in a gap between the all-light bending portion 6 and the light receiving bending portion 8, and the light shielding plate 9 has a bending portion 6 when tuning. The through hole 10 for optically communicating 8) is laid out.
상기 푸쉬버튼(2)은 종래와 같이 접동판(11)에 의해 푸쉬록크 되는 것으로 버튼(2)을 누르면 스위치 접점이 온으로 되고 당해 채널의 동조코일이 동조회로와 접속되어 선국이 이루어지며 이와 동시에 상기 램프가 점등되는 것이다.The push button 2 is push-locked by the sliding plate 11 as in the prior art. When the button 2 is pressed, the switch contact is turned on, and the tuning coil of the corresponding channel is connected to the tuning circuit, and tuning is performed. The lamp is turned on.
분지편(4)을 보유하는 분광체(3)와 연결봉(7)은 광전송율이 좋은 합성수지로 사출 성형한 것이며, 분광체(3)는 투명수지로 하고, 연결봉(7)은 일반적인 표시램프나 발광다이오드와 같이 적색수지로 한다. 분지편(4)과 전광절곡부(6) 및 수광절곡부(8)에는 램프(5)에서의 빛을 직각으로 굴절시키기 위한 호상만곡부(4')(6')(8')가 형성되어 있다. 미설명 부호(12)는 회로 기판이며, (13)은 텔레비젼 수상기의 조작 패널부의 반투명 표시판이고, (14)는 채널표시 기호이다.The spectrometer 3 and the connecting rod 7 having the branched pieces 4 are injection molded from a synthetic resin having good light transmission. The spectrometer 3 is made of a transparent resin, and the connecting rod 7 is a general display lamp. Like a light emitting diode, it is a red resin. The branch piece 4, the all-light bend portion 6, and the light-receive bent portion 8 are provided with arcuate curved portions 4 ', 6', 8 'for refracting the light from the lamp 5 at right angles. have. Reference numeral 12 denotes a circuit board, 13 is a translucent display panel of the operation panel portion of the television receiver, and 14 is a channel display symbol.
이러한 구성의 본 고안은 상기 연결봉(7)의 선단이 표시판(13)의 채널표시기호(14)에 접하도록 설치하여 사용하는 것으로 푸쉬버튼(2)중 어느 하나를 누르면 접동판(11)에 의해 록크되고, 스위치 접점이 온으로 되고 당해 동조코일(미도시)이 동조회로에 접속되어 선국이 이루어지며 이와 동시에 램프(5)가 점등된다. 램프(5)에서 발광되는 빛은 분광체(3)에서 각 분지편(4)으로 분광되어 만곡부(3')(4')에서 각각 직각으로 굴절되면서 절곡부(4)의 선단된다.The present invention of this configuration is to install and use the front end of the connecting rod (7) in contact with the channel display symbol (14) of the display panel 13 by pressing the push button (2) by the sliding plate (11) The lock is turned on, the switch contact is turned on, and the tuning coil (not shown) is connected to the tuning circuit, and tuning is performed, and at the same time, the lamp 5 is turned on. The light emitted from the lamp 5 is spectroscopically directed to each branch piece 4 in the spectroscope 3 and is bent at right angles in the bent portions 3 'and 4', respectively, to the tip of the bent portion 4.
이때 선국된 채널에 해당하는 푸쉬버튼(2) 이외의 푸쉬버튼(2)은 차광판(9)에 천설된 통공(10)이 절곡부(6)(8)에서 이격되어 있으므로 차광판(9)에 의해 절곡부(6)(8)간의 전광이 차단되며(제4도 (a)참조) 선국된 채널에 해당되는 푸쉬버튼(2)의 차광판(9)에 천설된 통공(10)만이 절곡부(6)(8)에 일치하므로 당해 분지편(4)의 절곡부(6)와 당해 연결봉(7)의 절곡부(8)간의 전광이 이루어진다(제4도 (b)참조).In this case, the push buttons 2 other than the push button 2 corresponding to the tuned channel are disposed by the light blocking plate 9 because the through hole 10 installed in the light blocking plate 9 is spaced apart from the bent portions 6 and 8. All light between the bent portions 6 and 8 is blocked (see FIG. 4 (a)), and only the through hole 10 installed in the light blocking plate 9 of the pushbutton 2 corresponding to the tuned channel is bent portion 6 (8), light is transmitted between the bent portion 6 of the branched piece 4 and the bent portion 8 of the connecting rod 7 (see FIG. 4 (b)).
절곡부(8)에 전달된 빛은 만곡부(8')에서 직각으로 굴절되어 연결봉(7)이 끝단쪽으로 전달되며, 그 끝단에서 당해 채널 표시기호(14)를 조사하게 되는 것이다.The light transmitted to the bent portion 8 is refracted at a right angle at the curved portion 8 'so that the connecting rod 7 is transmitted toward the end portion, and the channel indicator 14 is irradiated at the end portion thereof.
이상과 같이 본 고안에 의하면, 다수의 램프나 발광다이오드를 사용하지 않고 하나의 램트로서 선국되는 각 채널의 채널표시를 행할 수 있으므로 구조가 간단하게 되며 원가절감을 도모할 수 있는 효과가 있다. 또한 본 고안은 상술한 전자튜닝 유니트에만 국한되는 것이 아니고, 예컨대 차광판의 구조를 변경하는 것에 의하여 각종 표시장치에 적용할 수 있는 것이다.As described above, according to the present invention, since the channel display of each channel selected as one lamp can be performed without using a plurality of lamps or light emitting diodes, the structure can be simplified and the cost can be reduced. In addition, the present invention is not limited to the above-described electronic tuning unit, but can be applied to various display devices by changing the structure of the light shielding plate.
