Description

A letter input system, a mobile telephone having that and a input control method

The present invention relates to a character input apparatus, a mobile telephone system having the same, and a control method thereof, which will be described in more detail. A mobile telephone system having the same and an input control method thereof.

Nowadays, portable information terminals (hereinafter referred to as mobile phones) are widely used to become necessities of life, and the use class is gradually diversified into young and old.

Meanwhile, companies that provide mobile communication services provide users with various services such as text message transmission, mail service, and Internet service.

On the other hand, since the size of the telephone is very important in the mobile telephone, the number of keys of the dialing keyboard cannot be increased indefinitely.

Therefore, in the related art, characters are inputted by combining Korean / English with numeric keys of a dialing keyboard to have a plurality of key functions and reducing the number of keys.

A typical conventional character input device is composed of a keyboard arranged with a plurality of keys assigned with a scan code, a micom for scanning a keyboard, at least one key code data, and a key code buffer for storing a key code. According to the program, the scan code is read to produce ASCII code, and the scan buffer and ASCII code are provided through the key buffer.

Hereinafter, a conventional character input apparatus will be described with reference to the accompanying drawings.

1 is a view showing the arrangement of the numeric keys of a general dialing keyboard.

As shown in FIG. 1, the dialing button of the phone allows ten numeric keys' 1 2 3 4 5 6 7 8 9 0 '(Tenkey) to input three English letters and Korean characters, respectively. In addition, the control key and' * Include keys such as' (asterisk), '#' (shop), etc. In FIG. 1, Korean and other function keys are omitted for convenience.

Dialing a phone number with ten numeric keys on the dialing keyboard like this, assigning and calling a specific service with a control key. In order to input the English letters on the dialing keyboard, as shown in Fig. 1, the English letters are arranged on nine numeric keys 1-9. This allows you to enter all twenty six alphabetic characters using a few dialing key buttons.

The character input device of the dialing keyboard should refer to the key combination of FIG. 2 in order to recognize an alphabetic character arranged in the dialing key button of FIG. 1 in the character input mode.

In the dialing keyboard, as shown in the key combination of FIG. 2, the '2' key is inputted for 'A', the '2' key is inputted for the 'B', the '2' key is entered, ' You must enter 2, 2, and 2.

In addition, to input 'ABC', '2', no time input, '2' '2' key, no time input, '2', '2', '2' key is pressed.

When no input is provided to the microcomputer for a certain period of time, the microcomputer checks the key combination already entered in the '1' key and sequentially stores the corresponding English ASCII code in the key buffer. This key input method is low efficiency and the character input speed is very slow because the input time is delayed for each character combination for a certain time.

In addition, if the English input device supports both English upper and lower case letters, the character input mode must be changed from English upper case letters to English lower case letters by pressing a control key that is separately promised for lower case letters.

Therefore, an object of the present invention is to solve the conventional problems, and to provide a character input device, a mobile telephone having the same, and an input control method thereof, which enables simple key input of a letter in English.

As shown in FIG. 4, the most important feature of the English letter key 52 is a sequence key (*, 0, # that designates the number of English letters to be input from two or three English letters arranged in the English key (1 to 9). ) Is there.

In addition, in the embodiment of FIG. 4, a button (*) denoted by (SHC) designates a case input mode in order to support case. The '* (SHC)' button is used to specify the upper and lower case letters, and the first one when the alphabetic character number is already assigned second or third.

At this time, if the English key portion is simply configured to not support lowercase letters, only the alphabetic sequence number designation function should be used.

As shown in FIG. 4, the English letter key 52 assigns a 'Shift function' and an alphabetical order designation cancel function to input a case-sensitive key to the * key of the existing dialing keyboard (FIG. The key is assigned the function of entering the second question among the alphabets arranged in each key, and the # key is assigned the function of specifying the third character.

From the input of the sequence keys (*, 0, #) and the English letter keys (1 to 9), the microcomputer 12 generates 26 uppercase letters and 26 lowercase letters and displays them on the display device 60. Here, by selecting the control key 51, all the keys of the English alphabet key 52 can be inputted in Korean and numerals. Since this is the same as the conventional one, description thereof is avoided.

FIG. 5 is a diagram for inputting a lowercase English letter with the numeric key portion 52 of FIG.

As shown in Figure 5, the lowercase English letters are simply input by the sequence number keys (*, 0, #) and the English letters (1-9), the first English letter of the English letter written on each of the English keys (1-9) You do not need to press the sequence key (*, 0, #) separately.

6 is a diagram showing a key input for inputting an uppercase English letter, which is simply inputted by an uppercase letter designation key (*), a sequence number key (*, 0, #) and an English letter key (1 to 9). It is not necessary to press the sequence number key (*, 0, #) separately when entering the first alphabetic character of the alphabet written in each of (1 ~ 9).

In this case, various modifications may exist in the input method, and may be designed to be input by changing the order of the capital letter key (*) and the sequence key (*, 0, #).

Fig. 7 shows a second embodiment of the English alphabet key portion, in which the expressions (2) and (3) representing the order written on the 0 key and the # key, which are the sequence keys of the first embodiment, are replaced by 2nd and 3rd. Are the same, and the example of inputting alphabetic characters is shown in FIGS. 5 and 6 as in the first embodiment.

In addition, although not shown in the drawings may be represented by 2th and 3th.

Here, SHC on the * key is a compound word of shift and cancel, which combines the case change function and the cancel ordering function.

FIG. 8 is a third embodiment of the English alphabet key portion. (2) and (3), which denote the order inscribed on the 0 key and the # key, which are the sequence keys of the first embodiment, are the same, and only the case conversion function is not supported. The * key only displays the cancel function as shown in (C). This third embodiment can be applied to inexpensive mobile phone models. Since the example of inputting an English letter excludes a lowercase letter, only the uppercase letter shown in FIG.

On the other hand, you can also support only lowercase letters.

FIG. 9 is a fourth embodiment of the English alphabet key portion, and (2) and (3), which denote the order of being engraved on the 0 key and the # key, which are the order keys of the first embodiment, have been omitted, which is implied even if there is no separate indication.
