The present invention relates to an electronic typewriter that uses Hangul / English as a mixture, and more particularly, to an electronic typewriter that directly converts an incorrectly typed part without re-entering an incorrectly typed part when the English is typed in the Korean mode or when the Korean is typed in the English mode. It is about how to convert Korean to English directly.

Conventionally, only Korean characters can be used in Korean mode and only English characters can be used in English mode. Therefore, in order to correct this when typing English in Korean mode or Korean type in English mode, the wrong typed part had to be deleted and re-entered. Therefore, there is a problem in that an error caused by mode conversion is cumbersome and the typing time is delayed due to re-entry after deleting.

The present invention is to solve this problem, an object of the present invention by automatically converting the incorrectly typed portion by using the memory map for mode conversion when typing in the English mode or Hangul in the English mode The purpose of the present invention is to provide a Korean / English direct conversion method of an electronic typewriter that reduces typing time.

A feature of the present invention for achieving this object is that the system is controlled according to a signal input connected to the output side of the keyboard, a keyboard for inputting a signal such as letters, numbers, functions, etc. A central processing unit, a ROM having a program connected to the central processing unit to control a system according to an input signal, a RAM connected to the central processing unit to store variables used to control a system, and the central processing unit In an electronic typewriter comprising a display unit connected to an output side of the display unit for displaying a current state of the system, and a driving unit connected to the central processing unit for printing a key value input from the keyboard under the control of the central processing unit. If there is an initialization routine in which the system is set and a key input by the initialization routine, the input key A printing routine that prints the corresponding characters on paper and stores them in the buffer area, converts them into corresponding keys by the Korean / English correspondence table of the mode conversion memory map, and stores them in a temporary storage area. Reprinting routine that deletes the printout by entering the modifier key and reprints the deleted part with the key value stored in the temporary storage area, and clears the buffer area and the temporary storage area when the space bar or return device is entered. It is a Korean / English direct conversion method of an electronic typewriter composed of a clear routine.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram of an electronic typewriter, in which a system is controlled according to a signal input to an output side of a power supply unit 10 for driving a system and an output side of a keyboard 20 for inputting signals such as letters and numbers. The central processing unit 100 is connected, and the central processing unit 100 is connected to a ROM 30 having a program for controlling a system according to an input signal. In addition, the central processing unit 100 is connected to the RAM 40 for temporarily storing the variables necessary to control the system, and at the same time the display unit 50 for displaying the state of the controlled system on the output side of the central processing unit 100 ) Is connected, and the driving unit 50 for printing or performing a function according to the signal output from the central processing unit 100 is connected. 2 shows a memory map for mode conversion according to the present invention, in which a buffer area (1) storing key inputs, a Korean code table (2) containing a Korean font corresponding to a Korean key, and an English key corresponding to an English key are shown. The English code table (3) containing fonts, the Korean / English correspondence table (4) for converting the contents stored in the buffer area (1) into English code if it is English, and the English code if it is Korean, and the Korean / English correspondence table And a temporary storage area 5 for temporarily storing the converted contents. On the other hand, the printing routine L2 prints on paper if there is a key input by the determination step S104 of the initialization routine 1, and prints it on paper by the step S104 and then inputs it. Step S105 of storing the key value to be stored in the buffer area 1 of the mode conversion memory map of FIG. 2, and the contents stored in the buffer area 1 by the step S105. A step S106 of converting an input key into a corresponding key by the Korean / English correspondence table 4 of the map; and a temporary storage area 5 of all the conversion memory maps of FIG. ) In the order of step S107. In addition, the reprinting routine L3 determines whether a user inputs a correction mode key in order to recognize and correct that the user has typed English in Korean mode or Korean in English mode, and the determination step (S108). If it is determined in step S108 that the correct mode key is input, step S109 of deleting a wrongly typed part; and reprinting the contents of the temporary storage area 5 in the part deleted by the step S109. It is made in the order of (S110). At this time, if it is determined that the key is not input in the determination step (S108), the clear routine (L4) is performed. In addition, the clear routine L4 determines whether or not the space bar or the return key is input, and the contents stored in the buffer area 1 when the space bar or the return key is determined by the determination step S111. And step S112 for clearing the contents stored in the temporary storage area 5. At this time, if it is determined by the determination step S111 that the state bar or the return key is not input, the printing routine L2 receives and prints the key input again, and after the step S112, the initialization routine L1 is performed. Step S102 is repeatedly performed.

According to the present invention configured as described above, when power is supplied to the system by step S101 of the initialization routine L1, the system is initialized, and after all systems are initialized by the step S101, the initialization routine L2. In step S104, it is scanned whether there is a key input from the first mode keyboard 20. Then, the initialization chutin L1 determines whether there is a key input by the determination step S103, and if it is determined that there is a key input by the determination step S103, by step S104 of the printing routine L2. The character corresponding to the input key value is printed on paper, and the key value input by step S105 of the printing routine L2 is stored in the buffer area 1 of the mode map memory map of FIG. In step S106 of the printing routine L2 using the Hangul / English correspondence table 4 of the mode conversion memory map shown in FIG. 2, the Hangul is stored in the buffer area 2 in step S105. The English corresponding key is converted into the Korean corresponding key, and the converted value is stored in the temporary storage area 5 of all the conversion memory maps in FIG. 2 by step S107 of the printing routine L2. At this time, in order to recognize and correct that the user has typed the English in the Hangul mode or the Hangul in the English mode, it is determined whether the correction mode key is input in the determination step of the reprinting routine L3, and the determination step (S108). If it is determined that the correction mode key is input, the wrongly typed and deleted portion is deleted by step S109 of the reprinting routine L3, and the temporary author area 5 by step S110 of the reprinting routine L3. Reprint the contents stored in the deleted part.

When the step S110 is performed and it is determined that the space bar or the return key is input by the determination step S111 of the screw clear routine L4, the buffer area of FIG. 2 is cleared by the step S112 of the clear routine L4. 1) and contents stored in the temporary storage area 5 are cleared. On the other hand, if it is determined that the correct mode key is not input by the determination step S108 of the reprinting routine L3, the clear routine L4 is performed and the space bar or the return is determined by the determination step S111 of the clear routine L4. If it is determined that the key is not input, the printing routine L2 receives the key input and prints it on the paper. After performing the step S112 of the clear routine L4, the key input of the initialization routine L1 is scanned. Step S102 is repeated.

Herein, an embodiment is described to help understand the present invention. In other words, if you want to type `` technical data table '', after initializing the system by the initialization routine (L1), enter key `` technical data '' in the Hangul mode and type `` technical data '' in the printing routine (L2). Is printed on paper and stored in the buffer area (1), and then converted into English corresponding keys by the Korean / English correspondence table (4) and stored in the temporary storage area. Since the above "technical data" is correct for typing and does not need to be modified, pressing the spacer bar without entering the correction mode key clears the contents of the buffer unit 1 and the contents of the temporary storage area 5 and returns to the initialization step L1. Perform a key scan. At this time, you should input “TABLE” after changing the mode to English mode. If you type “TABLE” in Korean mode without changing the mode, the printing routine (L2) indicates “Su”. Strange characters such as "" are printed on paper and stored in the buffer section 1, and "TABLE" is stored in a temporary storage area by the Korean / English correspondence table. At this time, if the user recognizes a mistake and enters the correction mode key by the reprinting routine (L3), ”And re-arrange“ TABLE ”in the temporary storage area to the deleted location, then press the space bar to open the contents of the buffer section And the contents of the temporary storage area (TABLE) are cleared and the kisscan is executed.

As described above, the present invention can automatically correct the printing error according to the mode conversion using the Korean / English correspondence table of the mode conversion memory map, thereby making it easy to correct an error occurring during the mode conversion and to reduce the typing time.
