As described above, a process of operating a mobile mini-computer of a mobile phone type configured by one embodiment of the present invention as described above with reference to various embodiments will be described below.

[1] keyboards (27)

In the present invention, the keyboard 27, which is a means for the user to input information, is converted to a sub key 3 in order to overcome the limitation that all characters and symbols cannot be represented due to the space constraints of existing mobile phones, PDAs and keyboards. It is possible to express characters, symbols, special symbols, subscripts, etc. of countries around the world through the combination of the use of the keys and the existing switching keys and toggle keys. In order to increase the function of the keyboard by introducing a switch key called the sub key (3), and using it, the character representation of the limited main keyboard of the keyboard can be expanded to express two or more characters with one keyboard. .

That is, when the user selects a certain switching key, the control unit 50 controls the storage unit 70 so that the characters or symbols corresponding to the switching key selected by the user are on the main output unit 27 compared to other characters or symbols. By clearly displaying on the screen, the user can input the desired information while viewing the clearly displayed characters or symbols.

Based on these basic principles, the keyboard layout principle of the present invention allows the user to select the most probable method among consonants and vowel shapes, sounds, and associative sequences of related word meanings. By selecting the desired language from the various characters of the world by the user, and if the user selects a random language by the keyboard layout method developed independently, the spelling of the country is represented on the keyboard.

Typically, the keyboard layout is not only two types of PC-type and Canadian keyboard layout, but also to use the keyboard set by programming the user's discretion, in the case of the keyboard layout according to the present invention as shown in Table 1 below in the state the Num Lock key on the keyboard 27 is not toggled there is the character is displayed on the liquid crystal display, one of the numeric keyboard, oi, 2 b, 3 c, 4 Wh, 5 d, 6 ㅈ , 7 b, 8 ㅍ, 9 ㅊ, 0 o, "/" key f, school boy, "×" key is what that is, "Ao" key ㅌ, "+" key is sharper than around the heh The controller controls the display to be displayed in a simple manner , and inputs the Korean consonants ㄲ, ㄸ, ㅃ, ㅆ, and 두 by pressing the corresponding consonant twice or by using the Shift key.

keyboard PC type clockface Remarks / English (Hangul setting) Korean / English (English setting) Initial value Sub key Initial value Sub key One ㅅ, ㅆ ㅣ Tt Ll 'ㅅ' enter twice 'ㅆ' 2 ㅣ ㅏ Ss Kk 3 C, ㄸ ㅑ Ee Ii 'ㄷ' enter twice 'ㄸ' 4 M ㅛ Aa Yy 5 D ㅗ Ff Hh 6 ㅈ ㅠ Ww Bb 'ㅈ' enter twice 'ㅉ' 7 A, ㄲ ㅓ Rr Jj 'ㄱ' enter twice 'ㄲ' 8 ㅍ ㅕ Vv Uu 9 H TT Cc Nn 0 ㅐ ㅡ Dd Mm Of ㅂ, ㅃ ㅔ Qq .. 'ㅂ' enter twice 'ㅃ' × Lol ㅐ Zz . ㅌ ㅖ Xx Pp + ㅎ ㅒ Gg Oo Toggle key

If you press the Sub key formed on the right side of the body in the state that the consonant keyboard keyboard is formed as described above, the consonant keyboard display is converted into a vowel keyboard keyboard, where 1 of the numeric keyboard ㅣ , 2 is ㅏ , and 3 is ㅑ , 4 is ㅛ , 5 is ㅗ , 6 is ㅠ , 7 is ㅓ , 8 is ㅕ , 9 is TT , 0 is ㅡ , "/" key is ㅔ , "×" key is ㅐ , "-" key is ㅖ , "+" key causes the controller 50 controls so that a sharp display ㅒ than other characters or symbols of the surrounding.

For example, if the user wants to enter the word 'much', type 'c' twice or press the Shift key and type 'c', and select the Sub key to convert to vowel keyboard. After entering, release the Sub key you are holding and type 'ㅁ'.

In addition, the user selects the English-English conversion key 28 to input the English characters, the control unit 50 controls the memory unit, if the English characters are clearly displayed on the keyboard (27) Num Lock key (5) By default, English characters are displayed on the screen without being toggled. On the numeric keyboard, 1 is Tt, 2 is Ss, 3 is Ee, 4 is Aa, 5 is Ff, 6 is Ww, 7 is Rr, 8 is Vv, 9 is Cc, 0 is Dd, "/" key is Qq, "x" key is Zz, "-" key is Xx, and "+" key is Gg. 1 is Ll, 2 is Kk, 3 is Ii, 4 is Yy, 5 is Hh, 6 is Ww, 7 is Rr, 8 is Vv, 9 is Cc, 0 is Mm, and the "/" key ‥, "+ The key 50 controls the control unit 50 to display the Pp and the + key to display the Oo more clearly than other characters and symbols around it.

[2] charging of the power supply unit 120 using sunlight

The solar cell is converted into electrical energy by forming two solar cells around the main output device 20 and the auxiliary output device 2, which is the output device of the present invention, and then the inverter unit By converting the device to a constant voltage to continuously charge the battery it is possible to supply the power required by the device.

In addition, the battery for supplying power to the device is configured to be separated into the main battery 13 and the auxiliary battery 12 so that the auxiliary battery 12 continuously supplies power when the main battery 13 needs to be charged. It is possible to prevent the temporary power cut off due to battery replacement, so that the computer work using the device can be continuously performed.

The power control unit uses the timer's time information to cut off all power except the minimum power required for operation and standby of the device when no command is received from the user for more than a certain period of time during computer work. Afterwards, when the user opens a folder, inputs a command through a keyboard and touch screen, or receives an operation such as receiving a wireless phone, the user releases the folder.
