본 발명은 데이지휠식 전자 타자기나 프린터등에서 한글휠과 영문휠을 자동으로 인식하는 한영 겸용 전자식 타자장치에 관한 것이다.The present invention relates to a Korean-English electronic typewriter which automatically recognizes Korean and English wheels in a daisy-wheel type electronic typewriter or a printer.
종래의 한영 겸용 데이지휠식 전자 타자기에서 한영모드 변환시 휠을 바꾸어주고 키보드상에서 한영모드를 선택하는 키나 스위치가 있어 한글 인자시에는 사용자가 한글모드 위치를 변환함과 동시에 인자휠도 한글휠로 교환해야만 한글인자가 가능하였으므로 만약 휠을 교환하고 모드키를 변환하지 않고 인자하거나 반대로 휠을 교환하지 않고 모드키만 변환하여 인자하여 오타가 발생하는 문제점이 있었다.There is a key or switch to change the wheel in Korean-English daisy-type electronic typewriter and select Korean-English mode on the keyboard. Since printing was possible, there was a problem in that a typo occurred by changing the mode key without changing the wheel and changing the mode key or vice versa without changing the wheel.
본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로서, 한글 영문 모드를 선택하는 키나 스위치를 사용자가 선택하는 불편함을 없애고, 한영휠의 기준점으로 부터 일정한 위치에 포토센서를 부착하고 포토센서가 부착된 위치의 해당 자소 스포크(SPOKE)를 영문휠은 짧게하고 한글휠은 길게하여 포토센서에서 서로 다른 신호가 발생할때 주제어부에서는 하이, 로우 신호로 받아들여 한영모드의 자동으로 이루어지게한 것이다. 이를 첨부된 도면에 의하여 본 발명을 상세히 설명하면 다음과 같다.The present invention has been made to solve the above problems, eliminating the inconvenience of the user to select a key or switch for selecting the Hangul English mode, attaching the photosensor at a fixed position from the reference point of the Hanyoung wheel and attach the photosensor The English wheel is shortened and the Korean wheel is made long so that when the different signals are generated from the photo sensor, the main controller receives the high and low signals and automatically makes the Korean-English mode. The present invention will be described in detail with reference to the accompanying drawings as follows.
데이지휠의 홈포지션(Home position)으로 부터 몇스포크 떨어진 지점에 제 1 도에 도시한 바와 같이 포토센서를 장착하고 포토센서가 장착된 부위에 위치하는 휠의 형태를 제 2 도에 도시한 바와 같이 한글휠은 길게하고 영문휠은 짧게 만들어 포토센서가 어떤 휠인가를 감지할 수 있도록 구성하며 상기 포토센서는 제 3 도에 도시한 바와 같이 주제어부는 콘덴서(C1), 저항(R1),(R2)을 통하여 전원단자(V1)와 광트랜지스터(TR1)의 콜렉터에 연결하고 상기 광트랜지스터(TR1)의 에미터를 접시킴과 동시에 전원단자(V2)는 저항(R3)을 통하여 발광 다이오드(LED)의 애노드측에 연결하고 상기 발광 다이오드(LED)의 캐소드측은 접지에 연결하여 구성한 것이다. 이를 제 3 도와 제 4 도에 의하여 본 발명의 작용효과를 설명하면 다음과 같다.As shown in FIG. 2, a wheel is mounted at a position where the photo sensor is mounted as shown in FIG. 1 at a few spokes away from the home position of the daisy wheel, as shown in FIG. The Hangul wheel is made long and the English wheel is made short so that the photo sensor can detect which wheel. The photo sensor has a main controller as shown in FIG. 3 and a capacitor (C 1 ), a resistor (R 1 ), ( R 2 ) is connected to the collector of the power supply terminal (V 1 ) and the phototransistor (TR 1 ), and the emitter of the phototransistor (TR 1 ) is dished out, while the power supply terminal (V 2 ) is a resistor (R 3 ) Through the connection to the anode side of the light emitting diode (LED) and the cathode side of the light emitting diode (LED) is configured by connecting to the ground. 3 and 4 illustrate the effects of the present invention.
한영겸용 전자식 타자장치에 전원이 온되고 시스템 프로그램에 의해 시스템 초기화가 완료되면 캐리지 및 데이지휠은 정위치에 서게 된다. 키버퍼에 입력된 데이타 값이 없으면 데이지휠의 홈타이머를 체크하여 데이지휠이 홈포지션 위치에 있는지 확인하고 만일 데이지휠이 홈포지션 위치에 있지 않다면 데이지휠 모터를 구동시켜 데이지휠이 홈포지션 위치에 있음을 확인하면 한글 영문 모드를 체크하여 한글휠일 경우는 휠의 길이가 길기 때문에 발광 다이오드(LED)의 빛을 차단시켜 광트랜지스터(TR1l)를 오프시킴으로 주 제어부는 이를 하이신호로 받아들여 한글모드를 세트하며 영문휠일 경우는 휠의 길이가 짧기 때문에 발광 다이오드(LED)의 빛을 통과시켜 광트랜지스터(TR1)를 온시키므로 주 제어부는 이를 로우신호로 받아들여 영문모드를 세트하고 다시 키버퍼를 체크하게 된다. 이때 키버퍼에 입력된 데이타 값이 있으면 한영모드를 체크하여 해당 모드에서 데이타를 처리하게 되는데 한글모드가 세팅되어 있으면 한글처리 루틴으로 가서 한글을 처리하고 영문모드가 세팅되어 있으면 영문처리 루틴으로 가서 영문처리를 마친후 돌아와서 다시 키버퍼를 체크하여 상기 처리과정을 반복 수행하게 된다.When the power is turned on and the system program is initialized by the system, the carriage and the daisy wheel will be in the correct position. If there is no data value entered in the key buffer, check the daisy-wheel home timer to see if the daisy-wheel is in the home position. If the daisy-wheel is not in the home position, run the daisy-wheel motor to drive the daisy-wheel to the home position. If the Korean wheel is checked and the Korean wheel has a long length, the main control unit accepts this as a high signal and turns off the phototransistor (TR 1 l) by blocking the light of the light emitting diode (LED). If the English wheel is set, the wheel length is short, so the light from the light emitting diode (LED) is turned on to turn on the phototransistor (TR 1 ). Will be checked. At this time, if there is a data value input to the key buffer, it checks the Han-Young mode and processes the data in that mode. If the Hangul mode is set, go to the Hangul processing routine. If the English mode is set, go to the English processing routine. After the process, the process returns to check the key buffer again to repeat the process.
상기한 바와 같이 한글 영문휠의 기준점으로 부터 일정한 위치에 포토센서를 부착하고 이 포토센서가 부착된 위치의 해당 자소 스포크를 영문휠은 짧게 하고 한글휠은 길게하여 포토센서에 서로 다른 신호가 발생할때 주 제어부에서는 이를 받아들여 한영모드 변환이 자동으로 이루어지는 장점이 있는 것이다,As described above, when the photo sensor is attached at a certain position from the reference point of the Hangul English wheel, the spokes spoke at the position where the photoelectric sensor is attached are made shorter in English wheel and longer in Hangul wheel so that different signals occur in the photo sensor. The main control unit accepts this and the Korean-English mode is automatically converted.
