As shown in FIG. 1, two to four English letters (alphabet) are printed on the numeric keys together with the numbers.

In order to input an English letter, a user must first select a menu for inputting an English character, and then select a menu for inputting English.

In the English input mode as described above, the user inputs English characters, and key data of the corresponding English characters is generated in the order of printing of the English characters printed on the numeric keys according to the number of times the user presses the numeric keys.

For example, if the user wants to enter the English letter 'S', the user presses the numeric key '7'. Since the English letter 'PQRS' is printed on the numeric key '7', the user must press the numeric key '7' four times. You can enter 'S'.

In the above input method, it is necessary to press the numeric keys several times in succession so that the characters printed on the back of the numeric keys can be input, which causes a large number of key inputs, which may cause inconvenience to the user, and may also reduce the character input speed. There is discomfort.

The present invention has been made to solve the above problems, to reduce the number of key input by having a reverse key on the keypad to sequentially input a plurality of characters printed on the numeric keys of the keypad from the forward or reverse direction Has a first purpose.

In addition, a second object is to allow one of a plurality of function keys included in a keypad to function as the reverse key as a user sets a mode for text input.

These objects, features and advantages of the present invention will be more readily understood by reference to the accompanying drawings and the following detailed description. In describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the description thereof will be omitted.

The mobile phone including the keypad of the present invention includes a display unit, a speaker, a microphone and a radio frequency transmitting / receiving unit, a voice processing unit, and the like. The configuration is the same as that of a general mobile phone, and the functions of each component are the same. Will be omitted.

1 is a diagram illustrating an embodiment of a keypad according to the present invention.

In order to explain the keypad according to the present invention, only a part of the main body 50 of the mobile phone including the keypad 60 is illustrated.

The keypad 60 included in the main body 50 of the mobile phone includes a function key positioned at the upper end of the keypad 60 including a menu search and up, down, left and right movements, and numeric and character input. It consists of numeric keys for.

Numbers from 0 to 9 are printed on the numeric keys as representative characters, and alphabetic letters and Korean alphabets (collectively called 'letters') are printed on the numeric keys on which each number is printed. .

The alphabet of the English alphabet is 26 characters, the Korean consonants are 14 characters, the vowels are 10 characters, and two to four English letters and the Korean alphabet and vowels are assigned to one numeric key.

As the user continuously presses a numeric key on which a plurality of characters are arranged, the characters printed on the numeric keys are sequentially converted and input.

At this time, in order to input the third or fourth printed characters on the numeric keys, the user must press the numeric keys three or four times. In order to solve this problem, a reverse key (65) is used as a keypad ( 60).

That is, when the user presses the reverse key 65 and presses the numeric key, the character is inputted from the character printed at the end of the numeric key (reverse direction).

For example, if the user wants to input the letter 'V' arranged on the numeric key '8', the user presses the reverse key 65 and presses the numeric key '8' to print at the end of the numeric key '8'. 'V' is entered immediately.

In particular, when the reverse key 65 is pressed by the user once, the function of the reverse key 65 is set, and when pressed again, the function of the reverse key 65 is released.

That is, when the reverse key 65 is pressed once, reverse character input is set, and when pressed again, the reverse character input is released, that is, the forward character input is set. In this case, the reverse key 65 is set to forward and reverse character input. Functions as a switch key that causes the switch

As shown in FIG. 2, two reverse keys 65 may be separately provided at an upper end of a numeric key so that a user may freely input the reverse key 65 using a right or left hand when a character is input. have.

However, as described above, in order for the reverse key 65 to be separately provided to the keypad 60, the number of keys of the keypad 60 is increased, which is not economical in manufacturing a mobile phone.

To compensate for this, a volume control key 67 or another function key provided on the side of the main body 50 of the mobile phone in order to use the current keypad 60 without increasing the number of keys is provided. The function can be set to be compatible.

That is, when the user selects a mode for sending a short message or for inputting a text such as a phonebook entry or a schedule management, one of the call key, the end key, and the volume control key 67 which is not used for text input is reversed. The key map is software modified to function as the key 65.

When the keymap is changed so that the call key functions as a reverse key, the call key functions as a call key for call connection when the call key is not in the character input mode, and in the state of the character input mode, If a call connection request signal is generated during text input, the keymap returns to the non-text input mode, and the user enters a call key according to the call connection request signal.

Referring to the accompanying drawings, a description will now be given of a character input method in the keypad according to the present invention.

First, a mobile phone equipped with a keypad of the present invention (when a reverse key is provided separately) or a mobile phone that supports using a reverse key in response to a keymap change (when a function key combines a reverse key function) allows a user to input text. Select a menu (S10).

Menus for text entry include sending short messages, entering a phone book, and managing a schedule.

As described above, when the user selects a menu for inputting a character, presses the reverse key 65 (S20) and inputs a specific numeric key (S30), the corresponding character is input according to the number of times the numeric key is pressed.

That is, when the number key is pressed once (S40), the character printed on the last (n) of the number key is input (S50), and when the number key is pressed twice (S45), the last front of the number key (n) Characters printed in -1) are input (S47).

For example, when the user presses the reverse key 65 and presses the number key '9' once, the alphabet letter 'Z' is input, and when the number key '9' is pressed again, the alphabet letter 'Y' is input.

Pressing the numeric key three or more times after pressing the reverse key 65 does not reduce the number of key inputs compared with the conventional number of key inputs, and thus the subsequent steps are omitted in FIG. 3.

If the reverse key 65 is not pressed in S20, characters printed on the numeric keys are sequentially input in the same manner as in the conventional character input method (S35).

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, in the present invention, when the reverse key is pressed when the character is input from the keypad of the mobile phone, and the corresponding numeric key is sequentially input from the last character printed on the numeric key, the number of key presses is reduced and the character input time is reduced. There is an effect that can be faster.

In addition, if the function key included in the keypad of the cellular phone changes the key map to share the function of the reverse key, the existing cellular phone can be used as it is and economical and popularization effect can be increased.
