본 고안은 TV수상기용 연동식 채널의 선국표시 장치에 관한 것이다.The present invention relates to a channel selection apparatus of a linked channel for a TV receiver.

종래 연동채널방식의 TV수상기는 제5도에 도시한 바와같이, 채널스위치를 작동시키는 선국노브(K)와 각 채널 스위치에 대응하는 발광다이오드 홀더(H)가 별도로 설치되어 있기 때문에 부품주가 많아서 조립이 복잡하고 부품의 점유 공간이 넓게 되어 TV수상기의 전체 크기가 증대되며 원가가 상승되는 폐단이 있었다.In the conventional interlocking channel TV receiver, as shown in FIG. 5, the tuning knob K for operating the channel switch and the light emitting diode holder H corresponding to each channel switch are separately installed. This complicated and large part occupied space increases the overall size of the TV receiver and raises costs.

따라서 본 고안은 이러한 종래의 폐단을 해소하기 위하여 안출된 것으로 이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve such a conventional discontinuity and described in detail according to the accompanying drawings as follows.

제1도 내지 제4도에 도시한 바와 같이, 내부 일측에는 공지의 채널스위치(SW)의 스텝(S)이 삽지되는 삽지홈(2)을, 타측에는 공지의 발광다이오드(LED)가 유삽되는 홀더홈(3)을 형성하고, 홀더홈(3)의 내부에는 전방 통공(5)을 통해 표출되는 광유도편(4)을 내장하며 외측면에는 안내홈(7)이 요설된 안내편(6)을 돌설한 선국노브(1)를 공지의 전면 마스크(M)에 천설된 삽입공(H)에 출몰 가능하게 설치하고, 전면 마스크(M)에는 안내홈(7)이 유삽되는 안내봉(8)을 돌설하여서 된 것이다.As shown in FIGS. 1 to 4, an insertion groove 2 into which a step S of a known channel switch SW is inserted is inserted at one side of the channel, and a known light emitting diode LED is introduced at the other side. A guide piece 6 having a holder groove 3 formed therein, and having a light guide piece 4 exposed through the front through hole 5 inside the holder groove 3 and having a guide groove 7 formed on an outer surface thereof. ) Is installed in the insertion hole (H) installed in the well-known front mask (M) so as to protrude, and the guide rod (8) is inserted into the front groove (M) guide groove (7) It was made by ruling).

상기 선국노브(1)는 불투명 재질로 성형하며, 광유도편(4)은 투명한 유리 또는 합성수지로 성형하되 예컨대 적색을 띄도록 한다.The tuning knob 1 is formed of an opaque material, and the light guide piece 4 is formed of transparent glass or synthetic resin, for example, to have a red color.

미설명 부호(9)는 보강 리브이고 (PCB)는 채널스위치(SW)와 발광다이오드(LED)가 설치된 튜닝프린트 기판이다.Reference numeral 9 is a reinforcing rib and PCB is a tuning printed board provided with a channel switch SW and a light emitting diode LED.

이러한 구성의 본 고안은 다수의 선국노브(1)의 삽지홈(2)에 각 채널스위치(SW)이 스템(S)을 삽지하고, 홀더홈(3)에 각 채널용 발광다이오드(LED)를 유삽하여 하나의 선국노브(1)로써 발광다이오드(LED)의 홀더로서도 작용토록 한 것이다.According to the present invention, the channel switch SW inserts the stem S into the insertion groove 2 of the plurality of tuning knobs 1, and the LEDs for each channel are inserted into the holder groove 3. It is also intended to act as a holder of a light emitting diode (LED) as a single tuning knob (1).

즉, 제3도 (a)와 같이 비선국시(노브(1)를 누르지 않은 상태)에서는 채널스위치(SW)에 내장된 스프링(미도시)에 의해 선국노브(1)가 탄출되며, 제3도 (b)와 같이 노브(1)를 누르면, 삽지홈(2)에 삽지된 채널스위치(SW)의 스템(S)이 압입되어 스위치(SW)가 온(ON)되어 선국됨과 동시에 발광다이오드(LED)가 발광하게 된다.That is, in the case of non-tuning (a state in which the knob 1 is not pressed) as shown in FIG. 3 (a), the tuning knob 1 is discharged by a spring (not shown) built in the channel switch SW. When the knob 1 is pressed as shown in (b), the stem S of the channel switch SW inserted into the insertion groove 2 is press-fitted so that the switch SW is turned on and tuned, and at the same time, the light emitting diode LED ) Will emit light.

이때 발광다이오드(LED)는 홀더홈(3)에 유삽되어 지지되며, 발광다이오드(LED)에서의 빛은 광유도편(4)에 의해 외부로 유도되어 선국된 채널을 표시하게 되는 것이다.At this time, the light emitting diode (LED) is inserted and supported in the holder groove (3), the light from the light emitting diode (LED) is guided to the outside by the light guide piece (4) to display the tuned channel.

상기 조작에 있어 선국노브(1)는 안내편(6)의 안내홈(7)과 전면 마스크(M)의 안내봉(8)에 의해 안내되므로 일측으로 기울어지는 일 없이 원활하게 출몰된다.In the above-described operation, the tuning knob 1 is guided by the guide groove 7 of the guide piece 6 and the guide rod 8 of the front mask M, so that the stationary knob 1 is smoothly inclined without being inclined to one side.

이상과 같이 본 고안에 의하면 하나의 선국노브로써 채널스위치의 온, 오프 조작과 발광다이오드의 홀더로서의 작용을 동시에 행할 수 있으므로 구조가 간단하고 부품수가 감소되어 조립이 편리하고 원가를 절감할 수 있는 효과가 있다.As described above, according to the present invention, since one channel knob can simultaneously perform the on / off operation of the channel switch and the light emitting diode holder, the structure is simple, the number of parts is reduced, the assembly is convenient, and the cost can be reduced. There is.
