본 고안은 복사기의 스위칭 회로에 관한 것으로서 특히 복사기 덮개에 스위치를 부착 시켜서 대량 복사시 기존의 플레이 버튼 스위치를 사용하지 않고 덮개의 스위치로서 플레이 기능이 수행되도록 하여 대량 복사시 사용자의 편의를 도모하고자 한 것에 주안점을 둔 것이다.The present invention relates to a switching circuit of a copier, and in particular, by attaching a switch to a copier cover so that the play function can be performed as a switch of the cover instead of using a conventional play button switch during mass copying, so as to facilitate the user's convenience in mass copying. The focus is on things.

종래의 복사기는 복사기 몸체 상부에 플레이 스위치를 부착시켜서 복사를 하고자 할때 복사기 유리판에 복사를 원하는 면을 얹어놓고 복사기 덮개를 덮은 다음 몸체 상부의 플레이 스위치를 온 시켜서 복사기가 구동되게 하였는데, 적은 매수의 복사기는 별 불편이 따르지 않지만 대량 복사시는 덮개를 덮고 스위치를 누르는 이중 동작에 많은 시간을 낭비하게 될뿐만 아니라 불편이 따르는 문제점을 가지고 있었다.In the conventional copier, when copying is attached to the top of the copier body, the copier is driven by placing the desired surface on the copier glass plate, covering the copier cover, and turning on the play switch on the top of the copier. Copiers do not have any inconvenience, but when mass copying, not only waste a lot of time in the double operation of covering the cover and pressing the switch, but also had the problem of inconvenience.

본 고안은 상기와 같은 종래의 문제점을 해결하고자, 복사기 몸체 상부의 플레이 스위치이외에 덮개에 의해 스위칭되는 플레이 스위치를 부착시켜 대량 복사시에 사용할 수 있게 함으로써 복사기 사용자의 편의를 도모하고 복사 시간을 단축 시키고자 한 것에 목적을 둔 것으로서 이를 첨부도면에 따라서 설명하면 다음과 같다.The present invention is to solve the conventional problems as described above, in addition to the play switch on the top of the copier body attached to the play switch is switched by the cover to enable the use in large-scale copying to facilitate the user of the copier and to reduce the copy time Its purpose is to explain it according to the accompanying drawings as follows.

제2도와 같이 복사기 몸체(1)상부에 기존의 플레이 스위치(2)를 부착시킨 동일면상에 덮개판(3)에 의해 스위칭되는 스위치(44)를 부착시킨다.As shown in FIG. 2, the switch 44 switched by the cover plate 3 is attached on the same surface on which the existing play switch 2 is attached on the copier body 1.

그리고 이 스위치(4)는 제1도와 같이 전원단자(Vcc)를 접속하고 타단은 콘덴서(C)와 저항(R)으로 구성된 미분기(5)에 접속하여 미분기(5)출력에서 다이오드(D)를 거쳐 멀티 브이브레이터(MV)에 연결하여 출력은 인버터(N)와 스위칭 트랜지스터(TR)를 통해 기존의 스위치(4)를 접속시킨 OR 게이트(G)의 타단에 연결하여 OR 게이트 출력은 복사기의 동작부(6)에 연결하여서 된 것이다.This switch 4 connects the power supply terminal Vcc as shown in FIG. 1, and the other end of the switch C and the resistor R. Is connected to the multi-brulator (MV) through the diode (D) at the output of the differentiator (5), and the output is connected to the conventional switch (T) through the inverter (N) and the switching transistor (TR). The OR gate output is connected to the operating section 6 of the copier by connecting to the other end of the OR gate G to which 4 is connected.

이와 같은 구성으로 형성된 본 고안의 동작 및 작용효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention formed in such a configuration as follows.

복사를 원하는 종이의 면을 복사기의 유리판위에 올려놓고, 복사기의 덮개를 닫으면 덮개판(3)을 닫으면 스위치(4)가 온되어 하이 상태의 신호를 나타내게 된다.When the surface of the paper to be copied is placed on the glass plate of the copier, the cover of the copier is closed, and the cover plate 3 is closed, the switch 4 is turned on to indicate a high state signal.

하이 상태가 유지되어 미분기(5)를 통과하면 임펄스가 만들어지고 이 펄스가 다이오드(D)를 통과하여 정류되어 임펄스가 멀티 브이브레이터(MV)에 인가되어 일정한 주기를 갖는 하이상태의 펄스를 발생하여 이 펄스는 인버터(N)를 통해 로우신호가 트랜지스터(TR)의 베이스에 걸리므로서 트랜지스터(TR)의 콜렉터에 접속된 OR 게이트(G)의 입력은 하이가 되어 출력에서 하이 신호를 출력시키는데, 이때 기존의 스위치(2)를 온시킬때에 하이 신호를 OR 게이트(G)에 인가시키므로서 출력에서 하이 신호를 출력시킨다.When the high state is maintained and passes through the differentiator (5), an impulse is formed, and this pulse is rectified through the diode (D), so that the impulse is applied to the multi-vbrator (MV) to generate a high state pulse having a constant period. Therefore, the pulse is applied to the OR gate G connected to the collector of the transistor TR by the low signal is applied to the base of the transistor TR through the inverter (N) to output a high signal at the output, At this time, when the existing switch 2 is turned on, the high signal is applied to the OR gate G to output the high signal at the output.

OR 게이트(G)의 출력에서 하이 신호가 출력되면 이에 접속된 복사기 동작부(6)가 구동되어 복사를 수행하게 된다. 또한 덮개판의 스위치(4)를 이용하지 않으면 OR 게이트(G)에 접속된 트랜지스터(TR)의 콜렉터는 로우 신호가 걸리게 되고 기존의 스위치(2)에 의해서만 복사기가 동작되게 된다.When a high signal is output from the output of the OR gate G, the copier operation unit 6 connected thereto is driven to perform copying. In addition, when the switch 4 of the cover plate is not used, the collector of the transistor TR connected to the OR gate G receives a low signal and the copier is operated only by the existing switch 2.

이와 같이 본 고안은 복사기의 덮개에 의해 스위칭되는 스위치를 부착시켜서 대량 복사기에 사용하게 되면 사용자의 편의를 도모할 수 있게 되고 복사 시간을 단축시킬 수 있게된 유용한 것이다.As such, the present invention is useful when it is possible to use a large volume copier by attaching a switch that is switched by a cover of the copier, so as to facilitate the user's convenience and to reduce the copy time.
