Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input device for a portable telephone including a PDC, a PHS, etc., and more particularly, to an input device which is foldable and has a small size and good operability. The present invention relates to a mobile phone provided with a mobile phone. 2. Description of the Related Art In recent years, portable telephones have been added with functions such as e-mail, Internet, image input / output, etc. in addition to voice calls, and have the opportunity to input long text such as addresses and e-mails in addition to telephone numbers. Is increasing. Generally, in a mobile phone, a number and a plurality of characters are assigned to one key, and in order to select a desired character or symbol, it is necessary to depress one key a plurality of times in some cases. Is complicated. For example, in order to input katakana "so", it is necessary to press the key "3" five times. In order to solve such a problem, there has been proposed a portable telephone in which a keyboard provided with numeric keys and alphabet keys is connected to an external terminal of the portable telephone so that a character input operation can be easily performed. FIG. 3 shows an example of a mobile phone in which a keyboard is connected to an external terminal. Mobile phone 3
00 is an antenna 301, a receiver 302, a display 30
3. Transmission unit 304, input key 305, cursor key 30
And a keyboard 309 connected to an external terminal via a connector 307 and a cable 308.
Are connected. The keyboard 309 includes a keypad 310 for inputting alphabets, kana, numbers, and the like. Such a keyboard 309 is connected to the mobile phone 3.
By connecting to 00, characters and the like can be input in the same manner as a keyboard of a personal computer or the like. [0005] However, in the conventional technique of connecting a keyboard to an external terminal, it is necessary to carry the keyboard with the portable telephone, which is inconvenient. Further, when the keyboard is miniaturized so as to be portable, there is a problem that it is difficult to input characters and the like. [0007] The present invention for solving the problems is directed to a portable telephone used for mobile communication, which comprises a main body having a plurality of input keys and a plurality of input keys. It is characterized by comprising a keyboard unit connected to the main body and foldable and stored in the main body, and an operation unit having a plurality of input keys and connected to the keyboard unit and foldable on the upper surface of the keyboard unit. An embodiment of a mobile phone according to the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. FIG. 1 shows a state in which a mobile phone input unit 101 and a folding keyboard unit 102 are opened. FIG. 2 shows a mobile phone input unit 101 and a folding keyboard. This is a state where the unit 102 is folded and stored. First, referring to FIG.
1. The state in which the folding keyboard unit 102 is open, that is,
A state in which keys can be input from the folding keyboard unit 102 will be described. The mobile phone 100 of the present invention includes a mobile phone input unit 101 and a folding keyboard unit 102 and has a structure that can be folded by hinges 105 and 106. [0010] The mobile phone input unit 101 includes a transmitting unit 304, input keys 305, and cursor keys 306, similarly to a conventional mobile phone. When inputting a telephone number or inputting a simple character, by pressing the input key 305 a plurality of times using this mobile phone input unit 101 as in a conventional mobile phone, it is possible to input numbers, alphabets, kana, and the like. It can be carried out. The foldable keyboard unit 102 includes keypads 107 and 108 together with a keyboard provided on the main body side of the mobile phone 100. Each keypad has a number from "0" to "9" or "A". ~ "Z" alphabet, "A" ~ "n" kana, "SPACE",
"TAB", "ENTER", etc. can be input. The folding keyboard unit 102 is provided with a folding detection unit 111, and the folding keyboard unit 10
2 detects the folded state and prevents erroneous key input. In addition, by detecting the state in which the folding keyboard unit 102 is opened, the keypads 107 and 108 are enabled, and the mobile phone input unit 101 has special functions,
For example, when the input key 205 or the cursor key 206 is pressed, a specific program can be activated. Note that the folding detection unit 111 does not necessarily need to be provided in the folding keyboard unit 102, and may be provided in the main body of the mobile phone 100 or both the mobile phone 100 and the folding keyboard unit 102. Next, means for storing the mobile phone input unit 101 and the folding keyboard unit 102 will be described. The mobile phone input unit 101 is connected to a folding keyboard unit 102 via a hinge 110. The folding keyboard unit 102 is connected to the mobile phone 10 via a hinge 109.
0 is connected to the main body,
Is folded only in the direction toward the main body of the mobile phone 100 as indicated by the arrow in the drawing. The mobile phone input unit 101 is provided with a folding keyboard unit 102 as indicated by an arrow in the drawing.
Folds only in side direction. FIG. 2 shows a portable telephone 100 according to the present invention.
2 shows a state in which 2 is folded and stored. As shown, the mobile phone input unit 101 appears on the surface of the mobile phone 100 in a folded state.
05, a cursor number 306 and the like can be used to input a telephone number and characters. According to the portable telephone of the present invention, the keyboard portion is folded and accommodated, so that when the folding keyboard portion is opened, the input of numerical values, alphabets, kana and the like can be performed using the keypad. Therefore, the operability when inputting a long sentence or the like by e-mail or the Internet is improved. In addition, since the folding keyboard can be folded and stored in the mobile phone main body, portability is not impaired.
