FIG. 2 illustrates a system block diagram for inputting a character or operating a function key and supporting a process of operation using the rotary Korean / English input device of FIG. 1.

That is, the Korean / English character input device system 200 includes a condenser microphone 201, an audio amplifier 202, a rectifier circuit 203 and a comparator 204, and potential meta 1, 2 (205) 206, and jog. An input signal of each of the switch 111 and the function key matrix 207 is input to the first microcontroller 208, and is connected to an output terminal of the first microcontroller 208. Decoder circuit 214 and a buffer connected to the output terminal of the second microcontroller 213 and the output terminal 210 and the corresponding infrared receiving module 211, RF receiving module 212 corresponding to the second microcontroller 213, And a third microcontroller 218 connected to the personal computer keyboard terminal 217 by connecting each of the gate circuits 215 to the key-dedicated microcontroller 216, while being connected to the output end of the first microcontroller 208. Up and Down LED Character Display (219) An audio synthesis circuit 222, an audio amplifier 223, and a speaker 224 are connected to the fourth microcontroller 221 connected to the output terminal of the first microcontroller 208. In the figure, 146 and 147 are LED lamps for operation mode display, 225 are decoder circuits, and 226 are LED display devices.

The present invention connects the dial 100 to the personal computer keyboard terminal 217 of the Hangul / English character input device system 200 to input characters in a rotary alignment and at the same time the left and right function keys 138 (139) By using) Morse code input method to enter the character as a detailed description of the operation is as follows.

That is, in order to input characters, when the Korean / English selection mode key 131 is pressed once, the function state of the key matrix 207 is recognized by the first microcontroller 208 and the key code is input by the key scanning operation. To decode the function key to recognize the pressed state of the Korean / English mode key 131, and the first microcontroller 208 detects the lamp ① of the LED lamp 146 indicating the decoded mode state of the key. When the key is pressed, the first microcontroller 208 transmits the key value to the third microcontroller 218 and the fourth microcontroller 221. The third microcontroller 218 decrypts the key value sent from the first microcontroller 208 and generates a character font value for displaying two upper and lower characters corresponding to the key value, thereby displaying the upper LED character display device 219. LED characters are displayed on the text display window 121, 122 by the LED display device 220, the fourth microcontroller 221 decrypts the key value sent from the first microcontroller 208, A character corresponding to the value is generated as a voice through the voice synthesis circuit 222 and then amplified by the audio amplifier 223 to generate sound by the speaker 224.

Then, if the English mode is selected through the Korean / English mode key 131, the Korean consonants and numbers and the fixed character indicating arrow 113 can be rotated while rotating the jog switch clockwise or counterclockwise through the jog switch 111. An English character and a special character printed on the fixed character board 114 are designated by the fixed character indicating arrow 113 'of the Korean consonant dial 113 in which') is printed.

At this time, when the jog switch 111 is rotated, the Korean consonant dial 113 and the Korean vowel character 112 rotate the special function key dial 110 together. When any English character printed on the fixed character board 114 is indicated by the fixed character indicating arrow 113 ', the upper and lower case letters of the indicated character are displayed on the character display window 121 and the lower case letters are displayed under the character display window 122. Special characters are displayed on the character display window 123 and numbers are displayed on the character display window 122.

When the upper input function key 132 is pressed, input of uppercase English letters and special characters of the fixed dial 114 is completed, and then a sound is inputted to the speaker 224, and the first microcontroller 208 sends a sound. The second microcontroller 213 is inputted through an infrared ray transmitting module 209 and an infrared ray receiving module 211 by inputting an angle code sent from the jog switch 111 located in the letter indicated by the fixed text indicating arrow 113 '. And the second microcontroller 213 decodes the position and sends the decoder circuit 214 selection code and data code to the buffer and gate circuit 215 to scan input by the existing key-only microcontroller 216. The value is sent to the personal computer keyboard terminal 217. At this time, if you want to input the lowercase letters of the English characters indicated by the fixed character indicating arrow 113 ', pressing the lower input function key 133, the character input process is the same as the above process. In order to remove a character because an input character is incorrectly inputted, the character can be easily erased by pressing the character erase function key 134 in the order of the most recent character, and the same result can be achieved by using the erase only function key 143.

When the Korean / English code key 131 is pressed once in the English mode, the above operation is repeated, and the speaker 224 outputs a key tone confirming the press of the key, and the LED lamp is turned on to move to the Korean mode. Switch. In the Hangul mode, the character is indicated by the rotating character indicating arrow 114 'printed on the fixed character board 114. The movement of the character is selected by rotating the jog switch using the knob groove of the jog switch 111, and then rotating the character. The character displayed by the character indicating arrow 114 'is performed in the same manner as the operation performed in the function of the English character input mode. At this time, if the upper input function key 132 is pressed, the designated character of the Korean consonant plate is input, and if the lower input function key 133 is pressed, the designated character of the vowel plate is input. If the character input is wrong, the character erase function key 134 can easily erase the characters in the order of the most recently input characters. If you press the Hangul / English mode key 131 in the Hangul mode, you can enter the key value from F1 to F12 of the special function mode dial 110 through the same function key input process described above, LED lamp 146 to check the mode ) The lighting moves.

In addition, when the Hangul / English mode key 131 in the special function mode is switched to the first English input mode again through the same function key input process.

The function keys 131 to 134 are function keys used in the personal computer by rotating the jog switch 111, and the function keys 135 to 145 perform the same operations as the function keys used in the personal computer. Each function key operation is performed by a separate function key group for inputting the input port of the first microcontroller 208 in a scancode manner by the first microcontroller 208. After reading the key input state through the key input state, the key input state is decoded and the converted value is output to the decoder circuit 214, the buffer and the gate circuit 215 so that the second micro controller 213 can recognize the ASCI I code value.

On the other hand, Morse mode key 123 is a function key for switching the character input mode to Morse mode to easily switch Morse code by the toggle function, when the Morse mode is selected, the first microcontroller ( 208 operates as a key input operation program in Morse mode and turns on LED lamp 146.

When the morse mode is entered, the morse code may be generated using the left function key 138 and the right function key 139.

That is, when the left function key 138 is pressed, the key state of the function key matrix 207 is recognized by the scan key code input operation of the first microcontroller 208, the key value is decoded, and the first micro controller is decoded. A frequency already set in the counter circuit of 208 is generated to amplify the signal through the audio amplifier 223 and then transmit a single sound to the speaker 224. At this time, if the key is not returned while pressing the same key, the set single tone is transmitted periodically.

When the right function key 139 is pressed, the key is recognized in the same manner as the function key input operation and the set long sound is periodically transmitted. Accordingly, the first microcontroller 208 generates a morse code combination by adjusting the pressing time of the two keys for a suitable time with only the left function key 138 and the right function key 139, and transmits the input state and sound of these keys. After generating and converting the state to the general morse code, the first microcontroller 208 outputs the converted value through the decoder circuit 214, the buffer and the gate circuit 215 in the same manner as the character input method described above. If the Morse code is input incorrectly, the left function key 138 and the right function key 139 are simultaneously pressed or the character erase function key 134 is inputted in the order of recent input characters in the same manner as the above key input process. You can delete a character.

The morse code tone generating speed adjusting terminal 123 ″ is a volume terminal for the user to arbitrarily adjust the morse code sound generating speed according to the morse code learning progress.

The microphone 148 amplifies a specific single tone generated by the user with the condenser microphone 201 by the audio amplifier 202, converts the signal to a DC level through the rectifier circuit 203, and then initializes the initial sound through the comparator 204. The first microcontroller 208 recognizes the short and long sound durations, thereby finally recognizes the sound as a Morse code, converts the code, and inputs the characters in the same process.

The present invention as described above is finally recognized as a voice or morse code to convert the code to input the characters in the same process as described above. In generating the morse code by voice, the user needs to adjust the sound generation speed according to the degree of learning. For this, the morse sound generation speed adjusting terminal 123 'is used. In FIG. 1, the audio terminal 149 is for connecting a separate earphone and the microphone terminal 148 ′ is for connecting a separate microphone.

In the above description, when using Morse mode, ASCII characters or special function keys that do not exist in the existing Morse code can be used to extend Morse code and to switch the use mode.

In the present invention, the second microcontroller 213 may be integrated into the first microcontroller 208 to perform character input or the like.

In other words, the key scan input of the function key matrix 207 of the first microcontroller 208, the position data input by the jog switch 111, and the predetermined single sound and long sound are input to the condenser microphone 201, and the audio amplifier is input. 202, the rectifier circuit 203, and the comparator 204 outputs the state, and the Morse mode input values by the left and right buttons of the function key matrix 207 are decoded and converted into corresponding scan code values, respectively. Then, the information is transmitted to the personal computer terminal 217 through a wired, infrared or RF transmission medium.

And, Figure 3 is another embodiment of the present invention, by specifying the character to be input through the movement of the LED lamp to input.

That is, the LED display 226 connected to the decoder circuit 225 connected to the first microcontroller 208 of FIGS. 2 and 3 is positioned up, down, left, or right around the LED lamp 226 '. Two characters are fixed-printed and displayed on the input device's fixed dial (100A '), forming a group of characters in three areas: English character group, Korean character group, number and special character group (including function character). When the mode is designated by the zero mode key 131, the left and right keys of the function key matrix 207 are used or rotated clockwise and counterclockwise by a separate rotary optical encoder or jog switch 111. The first microcontroller 208 changes the decoder position information while responding to the rotational speed, and at the same time moves the lighting position of the LED lamp 226 'to designate a corresponding character around the lit LED lamp 226', and functions. Press the key on the upper input key (132) and lower input key (133) to enter This completes the input. In the above, in the Korean mode, the movement of the lighting state of the LED lamp 226 'moves only the Korean character group and the number and special character group, and in the English mode, only the English group and the number and special character group.

Therefore, another embodiment of the present invention is to move the lighting of the LED lamp 226 ′ of the LED display device 226 to designate and input characters.

The present invention can be applied to the PDA, mobile phone and information devices not only can be used separately from the key value generated from the existing keyboard, but also letters around the characters printed by the indicator arrow by rotating the jog switch clockwise or counterclockwise After inputting the character by using the function key to input the character, press the character input key to output the jog switch position data code corresponding to the designated character position, and the microcontroller recognizes this output code. . In this case, if it is used to be compatible with the existing personal computer, it converts to ASCⅡ code and outputs the location code in other applications.

The function keys include a character selection switch key for selecting a letter board printed around a jog switch, an erasing key for easily erasing the last input character when a character is incorrectly inputted, editing a document, making the movement of a cursor convenient, and a computer game. It consists of a special function key for position movement, and the function key status is checked by the existing scanning method and the function key is pressed and the corresponding character code is transmitted to the generating main device.

The F1-F2 keys on the desktop keyboard are collected in a separate dial on the rotating dial, assigned as function key expansion for changes in the usage environment, and the function keys are used to enter characters. It operates by dividing the key input by the micro controller key input scan key method.

If you specify the character of the rotating plate for the elderly with low vision, the display device displays large letters to provide ease of use, and the character voice data corresponding to the rotating plate is output to the memory to output the character sound to the speaker for the visually impaired. Save and output the character sound corresponding to the designated character to the speaker.

In particular, the present invention switches to the Morse mode by using the selection key to provide a method for inputting a character using only two thumbs, and enters the character by inputting the Morse code using only two left and right arrow function keys.

When in Morse mode, pressing the left arrow button causes the speaker to output a repeating tone with a short period of time with a constant amplitude, allowing the user to configure the Make signal of the Morse code while listening to the number of repetitions of the tone. Pressing the speaker outputs a family repeating sound with a long period of constant tone, allowing the user to construct a Morse code Make signal while listening to the repetition of the tone sound.

Special characters other than Morse code can be used by inputting characters by rotating or LED input method after switching modes, or by adding Morse code extension codes.

When there are many kinds of characters to input, it takes up a small space and the user can conveniently check and select the characters and input the characters, and according to the change of character utilization used, the user places a separate key to provide convenience. Select one character among the characters printed on the rotating plate attached to the jog switch knob and the printed characters on the fixed plate around the rotating plate circle by rotating the jog switch clockwise or counterclockwise. When the switch is pressed, the microcontroller sends the digital position code for the jog switch rotation angle to the decrypted corresponding letter code to the generating main unit.

In particular, Morse mode allows the user to adjust the volume level of the tone by two function keys and the tone generator, adjust the tone of the tone, and adjust the tone make time short or long. The character input speed can be adjusted by adjusting the skill of the sign input method.

In addition, the present invention rotates the jog switch clockwise or counterclockwise to move the LED lamp around the printed character along the character string, and use the function key for inputting the character after specifying the character around the lit lamp Character can be input to further increase the convenience of use.

As described above, the present invention is intended to provide convenience to the user with a new arrangement of function keys that are compatible with the desktop personal computer keyboard and reduce the size of the existing keyboard character input device used in the notebook computer and prepare for the change of the use environment. It has the effect of miniaturization of the character input device such as a portable terminal, a PDA, a portable terminal, a wired telephone capable of transmitting a message, a remote control for a wall mount, and various information devices such as convenience of use.
