Problems solved by technology

[0006] In the above-mentioned conventional system, since symbols and letters are input according to the number of times each number key is pressed, there is a disadvantage that the number keys have to be repeatedly pressed two to four times to input at least one symbol or letter.

Embodiment Construction

[0014] see now figure 1 and figure 2 The preferred embodiment of the present invention will be described in detail.

[0015] First, at step 101, the flag register is cleared and the buffered label is cleared, and at step 102, the control unit 20 inputs a key signal from the key input unit 10 . Then, in step 103 to step 114, the control unit 20 detects whether the input key signal is one of the number key, asterisk (*) key and # character number (#) key, if the input key is one of them , then go to step 119. In step 119, the control mechanism 20 detects whether the flag register is cleared, and if the flag register is in the cleared state, it proceeds to step 120. In step 120 , the control unit 20 stores the result obtained by multiplying the input number key by 4 into the register, and in step 121 sets the flag register. Next, the control unit 20 returns to step 102 . Yet in step 119, if flag register is not cleared, control unit 120 just advances into step 122, thereby ...

Abstract

Disclosed is a method to produce character keys by key combination in a multi-key system, in particular to a method to input characters with combined number keys. The method includes the following steps: designate a tab according to the two input keys when inputting two number keys in turn; read the corresponding character according to the tab and display the read character.

Description

technical field [0001] The present invention relates to a method for generating character keys by combination of number keys in a system using multiple keys, more specifically, a method for inputting characters by combination of number keys. Background technique [0002] Typically, terminal equipment such as telephone systems or facsimile systems are programmed to enter characters using numeric keys. [0003] However, in the conventional system, in order to input different letters and symbols shown in Table 1 below, it is necessary to repeatedly press each number key, asterisk (*) key, pound sign (#) key, etc. [0004] 0 1 2 3 4 5 6 7 8 9 * # once ， Q A D G J M P T W ( [ twice - Z B E H K N R U X ) ] ...
