Abstract

When a key is inputted, in case it is not a letter typing key, it is checked whether the key is a correction key. When a correction key is inputted, the type correction function is conducted and checks that the counter reaches a certain figure. In case the count is less than a specific figure, the counter is added 1 to conduct the function and by performing the type function, and in case it becomes a certain figure, the ribbon is fed, with the counter being cleared so the type figure can be counted, then consequently returning to the key scan routine.

본 발명은 전자식 데이지 휠 타자기에 있어서 연속으로 오타 수정기능을 수행할때 인자시마다 리본을 피이딩시켜 리본이 느슨하게 풀어지는 것을 방지하는 리본 구동방법에 관한 것이다.The present invention relates to a ribbon driving method that prevents the ribbon from loosening by feeding the ribbon at every printing time when a continuous typo correction function is performed in the electronic daisy wheel typewriter.

데이지 휠 타자기에 있어서 인자된 오타를 삭제하기 위해 수정(Correction)테이프가 부착되어 있는데, 이 테이프는 일반 탄소리본보다 아래쪽에 위치하고 있기 때문에 오타 수정기능을 수행하려면 이 테이프를 햄머위치까지 리프트시켜야 한다.In the daisy-wheeled typewriter, a correction tape is attached to remove the typographical error. Since the tape is located below the normal carbon ribbon, the tape must be lifted to the hammer position to perform the typo correction function.

상기 동작을 연속적으로 반복 수행하게 되면 타자기의 리본 카세트가 진동을 하게 되고 이 진동에 의해 탄소 리본이 느슨하게 풀어지게 된다.When the above operation is continuously repeated, the ribbon cassette of the typewriter vibrates and the carbon ribbon is loosely released by the vibration.

그러므로, 이때 문자를 인자하게 되면 탄소리본이 제 위치를 이탈하였기 때문에 문자가 인자되지 않거나(리본이 느슨하게 풀어져 있는 경우), 데이지 휠 사이에 리본이 끼어 리본이 끊어지거나 문자가 비뚤어지게 인자되는 문제점이 있었다.Therefore, printing a letter at this time does not print the letter because the carbon ribbon is out of position (when the ribbon is loose), or the ribbon is caught between the daisy wheels, causing the ribbon to break or the letter to be skewed. there was.

본 발명은 상기 문제점을 해결하기 위해 안출된 것으로서, 오타 수정 기능 수행시 일정 수 이상 연속으로 수정을 하는 경우 리본이 느슨하게 되지 않도록 오타 수정수를 카운트하여 일정수가 되면 한번씩 리본 피이딩을 시키는 전자식 데이지 휠 타자기의 리본구동방법을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the electronic daisy wheel for counting the number of corrections to correct the typo correction so that the ribbon does not loosen when correcting more than a certain number of times when performing the typo correction function to perform the ribbon feed once It is an object of the present invention to provide a method for driving a ribbon of a typewriter.

본 발명은 전자식 데이지 휠 타자기에 있어서 오타 수정시 리본이 느슨하게 풀어지는 것을 방지하기 위한 리본 구동방법으로서, 카운터를 이용하여 연속 오타 수정수를 카운트하고 일정수가 되면 리본을 피이딩(Feeding)시켜 리본이 느슨해지는 것을 방지하여 일정수 이상 연속으로 오타를 수정하는 경우 인자가 정확하게 되도록 하며, 연속적으로 오타를 수정하지 않는 경우에는 문자를 인자한 후 리본을 피이딩 시켜 주므로써 상기 기능을 수행할 필요가 없다.The present invention is a ribbon driving method for preventing the ribbon from loosening when a typo is corrected in an electronic daisy-wheel typewriter, and counting the number of consecutive typo corrections using a counter and fed the ribbon when a certain number of ribbons are fed. It prevents the loosening to correct the typos in a certain number of consecutive errors, and if the typos are not corrected continuously, it is not necessary to perform the function by feeding the ribbon after printing the characters.

이하에 첨부된 도면에 의거하여 본 발명의 실시예를 상세히 설명한다.Exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명의 블럭도를 나타낸 것이다. 본 발명의 전자식 타자기는 데이타를 저장하는 램(3)과, 본 발명의 제어수단인 프로그램이 내장되어 있는 롬(2)과, 캐리지를 이동시키는 캐리지 모터구동부(6)와, 라인 피드를 수행하는 라인피드구동부(4)와, 데이지 휠을 선택하는 데이지 휠구동부(8)와, 리본 피딩을 수행하는 리본구동부(5)와, 햄머링(Hammering)을 수행하는 햄머구동부(7)와, 키입력을 받는 키 보드부(9) 및 상기 각 소자를 제어하는 중앙처리장치(1)로 이루어졌다.1 shows a block diagram of the present invention. The electronic typewriter of the present invention is a RAM (3) for storing data, a ROM (2) containing a program which is a control means of the present invention, a carriage motor driving unit (6) for moving the carriage, and performs a line feed A line feed driver 4, a daisy wheel driver 8 for selecting a daisy wheel, a ribbon driver 5 for ribbon feeding, a hammer driver 7 for hammering, and a key input It consists of a keyboard unit 9 receiving and a central processing unit 1 for controlling each element.

상기 구성된 본 발명의 동작을 제2도에 도시된 흐름에 의거하여 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above based on the flow shown in FIG.

먼저, 연속하여 수정되는 횟수를 카운팅하는 연속 카운터를 클리어시킨다. 즉, 카운트를 할 수 있는 준비상태를 만들어준다.First, the continuous counter that counts the number of consecutive modifications is cleared. That is, it prepares to be ready to count.

키가 입력되었는가 키스캔을 수행한 후 키가 입력되면 키 입력을 받아 인자키인 경우에는 키 인자를 수행하고, 인자키가 아닌 경우 수정비(Correction Key)인가를 확인한다. 수정키가 아닌 경우에는 입력된 키에 상응하는 처리를 수행하고, 수정키가 입력되었으면 오타수정기능을 수행하며, 카운터가 일정수 "5"가 되었는가를 체크하게 된다. 일정수가 안되었으면 카운터를 "1" 증가시켜 상기 기능을 수행하고, 연속해서 오타 기능을 수행하여 일정수가 되면 리본을 한번 피이딩시키고 카운터를 클리어시키므로써 다시 오타수를 카운팅할 수 있도록 준비한 다음 키스캔 루틴으로 되돌아간다.If a key is input or a key is input after a key scan is performed, the key is received. If the key is a print key, the key is printed. If the key is not a print key, the key is checked. If it is not a correction key, processing corresponding to the input key is performed. If a correction key is input, a correction function is executed, and it is checked whether the counter has become a predetermined number "5". If a certain number is not reached, increase the counter by "1" to perform the above function, and perform the typographical function continuously. When the predetermined number is reached, the ribbon is fed once and the counter is cleared so that the counter can be counted again. Go back to the routine.

본 발명에서는 연속해서 5문자를 수정하는 경우 한번씩 리본을 피이딩시켜 주므로써 카운터는 5자되면 리본을 피이딩시켜 주게 된다.In the present invention, the ribbon feeds the ribbon once when five characters are modified continuously so that the counter feeds the ribbon when five characters are used.

만약, 연속해서 수정키가 입력되지 않는 경우에는 문자를 인자한 후 리본 피이딩을 시켜주므로써 상기한 바와같은 리본 피이딩기능을 수행할 필요가 있다.If the modifier keys are not input continuously, it is necessary to perform the ribbon feeding function as described above by printing the characters and then feeding the ribbon.

본 발명에 따르면, 연속적으로 오타 수정기능을 수행하는 경우 리본이 느슨하게 풀어져 문자가 인자되지 않는 문제점을 일정수마다 한번씩 리본피이딩시켜 주므로써 해결할 수 있어 인자가 안되거나 리본이 끊어지는 것을 방지할 수 있을 뿐만 아니라 인자의 품질을 향상시킬 수 있다.According to the present invention, when the continuous typo correcting function, the ribbon is loosely loosened and the character is not printed, which can be solved by feeding the ribbon once every predetermined number to prevent the printing from being broken or the ribbon being broken. In addition to this, the quality of the factor can be improved.
