컴팩트 디스크 플레이어의 도어 개방회로Door opening circuit of compact disc player

첨부된 도면은 본 고안에 따른 컴팩트 디스크 플레이어의 도어 개방 회로도이다.The accompanying drawings are door open circuit diagrams of a compact disc player according to the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

M : 도어 개폐용 모터 Q1 : 스위칭 트랜지스터M: Door opening and closing motor Q1: Switching transistor

SW : 도어 개방용 스위치SW: Door open switch

본 고안은 백업용 전원을 이용하여 컴팩트 디스크 플레이어의 도어를 개방하기 위한 회로에 관한 것이다.The present invention relates to a circuit for opening a door of a compact disc player using a backup power supply.

현재 컴팩트 디스크 플레이어의 대부분은 도어가 프론트로딩 방식인 바, 이 경우 재생상태에서 정전 혹은 전원 코드를 뽑은 상태에서 이동할때 셋트 내부에 장착되었던 디스크를 빼낼 수 없는 불편함이 있었다.Most of the current compact disc players have a front-loading door, which is inconvenient to remove the disc installed in the set when moving in the state of power failure or unplugging the power cord.

따라서, 본 고안은 이러한 사정을 감안하여 안출한 것으로서 컴팩트 디스크 플레이어 내부에 있는 백업용 전원을 이용하여 정전시나 전원코드를 뽑은 상태에서도 필요시에는 컴팩트 디스크 도어를 개방할 수 있도록 한 컴팩트 디스크 플레이어의 도어개방 회로를 제공하는데 그 목적이 있다.Accordingly, the present invention has been devised in view of the above situation, and the door of the compact disc player can be opened by using the backup power supply inside the compact disc player so that the compact disc door can be opened when necessary even in a power outage or when the power cord is unplugged. The purpose is to provide a circuit.

이러한 목적을 달성하기 위한 본 고안은 직류모터의 일단을 트랜지스터의 콜렉터에 연결하고, 백업용 전원을 트랜지스터의 에미터에 연결하며, 주전원을 트랜지스터의 베이스에 연결하여 주전원이 오프될 경우 백업용 전원을 이용하여 도어를 개방시키도록 구성시켜서 된 것이다.The present invention for achieving this purpose is to connect one end of the DC motor to the collector of the transistor, the backup power supply is connected to the emitter of the transistor, the main power is connected to the base of the transistor to use the backup power supply when the main power is off It is configured to open the door.

이하, 본 고안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 컴팩트 디스크 플레이어의 도어 개방회로도를 도시한 것인바, 이에 도시한 바와같이 도어 개폐용 직류모터(M)를 제어하는 입력단에 트랜지스터(Q1)의 콜렉터를 다이오드(D1)를 통해 연결하고, 트랜지스터(Q1)의 베이스에는 저항(R3)을 통해 접지시킨다. 그리고, 트랜지스터(Q1)의 베이스는 다이오드(D1)과 저항(R2)을 거쳐 주전원(B+)에 연결하고, 트랜지스터(Q1)의 에미터는 저항(R1)을 통해 베이스에 연결함과 동시에 스위치(SW)을 통해 백업전원에 연결한다.FIG. 1 illustrates a door opening circuit diagram of a compact disc player according to the present invention. As shown in FIG. 1, the collector of the transistor Q1 is connected to the diode D1 at an input terminal for controlling the door opening / closing DC motor M. As shown in FIG. It is connected via the ground of the transistor Q1 through a resistor R3. The base of the transistor Q1 is connected to the main power supply B + through the diode D1 and the resistor R2, and the emitter of the transistor Q1 is connected to the base through the resistor R1 and at the same time the switch SW To backup power.

이와같이 구성된 본 고안의 회로의 동작상태를 살펴보면, 전원코드에 전원이 공급되는 상태에서는 트랜지스터(Q1)의 베이스에 주전원(B+)이 저항(R2)과 다이오드(D1)를 통해 공급되므로 트랜지스터(Q1)는 턴온되지 않는다.Looking at the operating state of the circuit of the present invention configured as described above, since the main power source B + is supplied to the base of the transistor Q1 through the resistor R2 and the diode D1 in a state where power is supplied to the power cord. Is not turned on.

그러나, 정전 또는 셋트의 이동으로 인하여 전원 플러그를 뽑은 경우, 주전원(B+)이 저항(R2)을 통해 공급되지 않음으로 트랜지스터(Q1)의 베이스가 로우레벨이 되어 트랜지스터(Q1)은 턴온되는바, 스위치(SW)를 온시킬 경우에 한해서 백업 전원을 통해 컴팩트 디스크 플레이어의 도어를 작동시키는 모터(M)가 회전하게 되어 도어가 오픈될 수가 있다.However, when the power plug is unplugged due to power outage or movement of the set, since the main power source B + is not supplied through the resistor R2, the base of the transistor Q1 becomes low level and the transistor Q1 is turned on. Only when the switch SW is turned on, the motor M, which operates the door of the compact disc player through the backup power source, rotates so that the door can be opened.

이와같이 동작하는 본 고안은 컴펙트 디스크 플레이어의 재생시 정전이 되거나 전원 코드가 뽑혔을 경우 백업용 전원을 이용하여 모터를 회전시킴으로써 도어를 개방할 수 있는 특징으로 지닌 것이다.The present invention, which operates as described above, has a feature of opening a door by rotating a motor using a backup power source when a power failure or power cord is unplugged during the playback of a compact disc player.
