Abstract

The method inputs English characters using 10 numeric keys. The method comprises the steps: (A) checking that an input key is '*'; (B) sending error signal for non-numeric key input when '*' key is not input in the step (A); (C) checking a number of the same key input and displaying a character according to the number of the same key inputs which is determined by a character table; (D) counting the number of the same key inputs and storing a character corresponding to the number on a temperary buffer; (E) registering the character stored in the temporary buffer when input key is '*' in the step (A) and clearing the temporary buffer; and (F) sending error signal when no character is sored on the temperary buffer in the step (E).

The present invention relates to a key input method in an office device or various devices having a Ten key, and more particularly, to a method of inputting alphabets as well as numbers using the ten key.

In general, office equipment or various key input devices have alphabetic and numeric keys, respectively, and their input methods are also independently recognized. Therefore, the circuit requires many circuits such as the English letter key circuit and the numeric key circuit. Due to these key input devices, the product has a limit in miniaturization.

Accordingly, an object of the present invention is to provide a method for inputting English letters using numeric keys.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram according to the present invention, having a function key and a numeric key, and when those keys are pressed, a ten key board 10 for outputting an electrical signal thereto, and the output of the ten key board 10 is binarized. Receives the key data generation unit 20 for converting and outputting the machine language and the binarized ten key data outputted by the key data generation unit 20, and outputs a beep signal every time a key is input, and converts it into alphabetic data according to the number of key inputs. A microcomputer 30 for converting and outputting a display signal for displaying the same, a speaker unit 40 for receiving a beep signal from the microcomputer 30, converting the audible signal into an audible signal, and displaying the signal from the microcomputer 30. The LCD unit 50 receives a signal and displays the same on a predetermined display device (LCD).

2 is a flow chart according to the present invention, a first step of checking whether or not the "*" key data is input, and if the "*" key data is not input in the first step check whether the numeric key data input If the other key data input is different than the second step of outputting a warning sound and ending the step, and if the same key is repeatedly inputted a predetermined number of times when the numeric key is input in the second step, the character corresponding to the input number when the same number is repeated A third process of circulating data, a fourth process of storing a value determined by circulating in the third process at a time when the same number is not repeatedly input in the third process or temporarily after performing the third process; If the input key data is "*" key data in the first step, if there is data stored in the temporary buffer, the value is registered and then the temporary buffer is cleared and terminated. And if there is no value stored in the temporary buffer, a fifth process of outputting a warning sound and ending the process.

3 is a table of alphabets and numbers corresponding to the type and number of numeric key inputs in the present invention.

Therefore, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

First, the principle of the present invention is briefly described.

The present invention is to implement a method that can input both English letters and numbers with only one numeric key that the keyboard had both an English letter key and a numeric key in accordance with the number of times the numeric key is input using a predetermined memory. It is possible to replace with the input of the English letter so that when the numeric key is repeatedly input a predetermined number of times to replace the English letter corresponding to the number of times. However, if the number is input four times, it is regarded as the original number input.

In order to realize the above principle, in the present invention, the microcomputer 30 has a flow as shown in FIG. 2, and first, in step 101, when there is a key input, it checks whether the data is "*" key data. At this time, when the "*" key data is not input, the microcomputer 30 checks whether a numeric key is input in step 102. At this time, if the numeric key is not input, the microcomputer 30 outputs a warning sound, notifies that the number input is wrong, and returns to receive the number again.

However, when the numeric key is input in step 102, it is determined in step 104 whether the numeric key data has been previously input. In step 106, it is stored in a temporary buffer and returned to step 101 above. At this time, if the "*" key is not input again, repeating the steps (102) to (106) to circulate the characters stored in the temporary buffer. For example, if the number "2" is taken as an example, as shown in FIG. 3, pressing 2 once selects "A", then pressing * registers "A", pressing 2 twice selects "B". Then press * to register "B", press 2 3 times to select "C", then press * to register "C", press 2 4 times to select "2" and press * to enter "2". "Is registered, pressing 2 five times selects" A ", then pressing * registers" A ".

However, if there is a * key input in step (101), the microcomputer 30 proceeds to step (107) to check whether predetermined data exists in the temporary buffer.

If the predetermined data exists in the temporary buffer in the check, it is registered in step 108 and the contents of the temporary buffer are cleared in step 109. When there is no data stored in the temporary buffer in step (107), a warning sound is output through the speaker unit 40 and the process returns to step (101). The buffers are all used by allocating a predetermined area inside the microcomputer 30, and anyone skilled in the art can understand the detailed description thereof.

As described above, the present invention has the advantage of being able to input an English letter as an Arabic numeral key.

Claims (1)

In the data input method using the numeric keyboard, a first step of checking whether or not the "*" key data is input, and if the "*" key data is not input in the first step, checks whether the numeric key data is input. If the other key data input, other than the second step of outputting a warning sound and the end of the step, and if the same key is repeatedly input a predetermined number of times when the numeric key input in the second process is to correspond to the number of times when the same number of repeated inputs A third step of circulating the character data, and a fourth step of storing the value determined by circulating in the third step at a time after the third step is performed, if the same number is not repeatedly inputted in the third step, and ending the step. And when the input key data is "*" key data in the first step, if there is data stored in the temporary buffer, register the value and then click the temporary buffer. And shut down the English input method using the number keys, characterized in that the configuration in the fifth step of if there is no value stored in the temporary buffer to the output end after the beep.
