BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic devices requiring input and output such as letters / numbers / symbols, in particular to input devices of various portable terminals or remote controllers including mobile phones.

Today, convergence and complexion of technologies are rapidly progressing as convergence progresses that add various functions to various portable devices including mobile phones.

However, the addition of functionality inevitably leads to an increase in size and weight, which is in violation of the basic purpose of portable devices, so that mobile devices such as mobile phones, personal digital assistants, game consoles, etc. To make it easy and convenient, to have a light weight and small size is a very important factor.

However, there is a difficult technical limitation in designing such mobile devices in a small size, which is a problem regarding the usability of the keypad.

In particular, due to the popularity of short message services (SMS), making keypads easier and more convenient to use is becoming more important than ever before, and manufacturers have reduced the size of their devices to increase their portability. At the same time, there have been requests from various consumers to increase the size of liquid crystal displays (LCDs) for smooth reproduction of more diverse contents.

However, in order to provide a wider display area, the area occupied by the keypad must be reduced. In this case, as the keypads become smaller in size, it is likely that other keys will be pressed repeatedly when contacted between the finger and the 'keys' of the keypad. .

Therefore, minimizing such redundancy, but as a key function of the keypads to ensure that users do not interfere with data input and output, and to provide a means for faster input and output is a very important problem in the design of portable devices.

Keypads for mobile phones generally have a basic configuration as shown in FIG. 1.

In addition to performing functions such as data input and output, the 'keys' used to dial numbers are typically provided in a 4x3 matrix.

The matrix described above includes the first column numbers of the numbers "1", "2", "3", the second column numbers of "4", "5", "6", and the "7", "8". The third row of "," 9 " and the first and second function keys and the fourth row of the number " 0 &quot;

And as an additional array of other keys located above this array, it may be arranged to perform scrolling functions such as starting and ending telephone calls, performing various other functional menus, or browsing the Internet or screen.

One approach that manufacturers typically take is to reduce the size of each of the individual keys in the keypad.

It reduces the overall footprint or size of the keypad.

However, there is a limit to reducing the size of the keypad, and if the keypad is made too small, it is difficult for the user to press the desired key without accidentally pressing the neighboring keys.

Other approaches are usually concealed and designed to be opened and used when needed, but the keypad is still inconvenient.

Looking at the prior art attempted to achieve this purpose is as follows.

First, as shown in the accompanying drawings, the sliding method of the keyboard large enough to be convenient to use while following the conventional traditional key input method in that the user manually inputs a lot despite the latest additional functions such as voice recognition. This is a compromised design, but in this case, the weight of the product increases or the position of the input keys has to be biased toward the bottom, which is inconvenient to use with only one hand.

In addition, as shown in Figure 2, when using a matrix layer structure menu or a character array using a kind of multi-directional switch, the user continues to look at the screen, the desired function or input through the above-described key combinations However, the biggest problem with this approach is that the user can see only one layer on the display described above, and it is difficult to remember where the key buttons or objects are located to operate a function. Not only does it often cause a loss of view of the entire contents of the menu structure, but also increases the number of key presses, which takes a long time when inputting / outputting data.

Practically, even in a portable device, if there is no space limitation, assigning one key to each number or letter like the keyboard of a computer can provide the fastest speed of manual input.

However, as described above, all portable devices have a space limitation in arranging a keypad, and therefore, the number and size of keys that can be assigned are inevitably limited.

Thus, a method of allocating several characters or functions for each 'key' in parallel or as a subdirectory in a tree structure is commonly used.

Thus, when a user wants to input specific data in a portable device, a user needs to touch a larger number of 'keys' than in a method of inputting a computer through a keyboard.

In particular, the input method configured as a matrix hierarchical structure as shown in the accompanying drawings of FIG. 2 of the above-described prior art is very difficult to intuitively remember the overall structure, so that the input method is viewed while the printed form is displayed on the keypad, or While looking at the displayed items, it is necessary to input sequentially along the selection path determined by the manufacturer, and thus the input speed becomes very slow, or it is inconvenient to input in a dark environment or while moving.

In addition, there is a method of providing a control such as a joystick when providing a scroll type input means in a portable device.

Usually, the sensing method in a joystick is known when the axial sensor or the switch is in four directions and in the eight directions.

For example, in the conventional embodiment corresponding to the case of using a sensor or a switch having eight directions, a method of assigning each 'key' to a keypad is as follows.

Divide each of the eight directions into north, south, east, west, northeast, southeast, southwest, and northwest for convenience; '1', 2 ',' 3 ',' 4 ',' 5 ',' 6 ',' 7 ' , Keys corresponding to the input of '8', '9' and '0', respectively, north, northeast, east, southeast, south, southwest, west, southwest and north twice, northeast twice, etc. Based on the assignment of the key, the user inputs data by moving the 'key' in each direction so as to correspond to a predetermined direction in order to input a number and operating a sensor or a switch.

In this case, however, since the layout of the keyboard is arbitrarily determined by the manufacturer, the user cannot remember this logically or intuitively. I had to confirm the location.

In addition, another disadvantage of this conventional approach is that the 'key' operation is used two or more times to achieve the input or control necessary for the input and output of various data. There is an impediment to use, such as significantly slowing down the speed of the system or increasing the input error.

An object of the present invention created in view of the above-described problems, the keypad according to the expansion of the display for electronic devices that require input / output, such as letters and numbers, in particular, various portable terminals or remote control devices including mobile phones In response to the reduction of the layout space, the usage can be intuitively memorized despite the reduced combination of keys, allowing data to be processed quickly using one or both hands without having to visually check the number plate or display. By doing so, it is to provide the usability and convenience of the device according to the input / output.

In order to achieve the above object, the present invention provides an input device for an electronic device that requires input and output of letters, numbers, and symbols, each position for dividing a circle into 12 at predetermined positions outside the main body of the electronic device described above. And at least one input means including a handle pointing a central position of the circle, and a handle detecting sensor for detecting a moving course of the aforementioned handle; A processor for processing a moving course detection signal of a steering wheel input from the handle detection sensor as described above through a previously stored program and logic circuit and transmitting the same to a confirmation means for later review; A mode switch key for switching the selection of the above-described input means so that the above-mentioned processor is divided into letters / numbers / symbols respectively; And a confirmation means for separately displaying the processing signal of the processor which processed the handle detection signal input from the above-described input means, the previously stored letters / numbers / symbols, and the movement map of the handle accordingly. .

According to the present invention configured as described above, when the above-described steering wheel is operated in the same direction as the twelfth part of a familiar watch, the steering wheel sensor senses the moving course of the steering wheel, that is, the position where the steering wheel passes, and inputs it to the aforementioned processor. .

In this way, when the operation state of the handle is input to the processor, the processor outputs a signal such as a letter, a number, or a symbol to the display device according to a pre-stored program and electrical logic circuit.

In this case, the above-mentioned checking means is the same as a display device of a conventional display device, for example, a mobile phone, and displays a moving map of letters / numbers / symbols previously stored in the above-described processor and a handle map accordingly, and displays the displayed characters. Alternatively, by displaying whether the user inputs a number or a symbol correctly by operating the above-described input means, the input operation is mastered upon initial use of the input device.

The above-described input means of the present invention may be configured as a tact switch for inputting, for example, a change value of a state electrically connected and connected to the processor according to a pressing or moving of a handle.

At this time, the handle of the above-described input means is a tact button to select the direction and the center to divide the circle into 12 in the initial contactless state, and return to the initial contactless state after the selection.

The handle detection sensor of the input means described above is a contact point in a tact path in 12 directions for conducting an electrical signal by selection of the aforementioned tact button.

In addition, the above-described input means may be, for example, a joystick input to the processor by converting the position signal in the 12-direction using an internal variable resistance value that changes according to the manipulation of the handle. When the input means for inputting a signal corresponding to each of the processor is satisfied.

In addition, the above-described input means may be installed on one side of the display device of the above-described electronic device, may be installed on both sides, it may be installed at predetermined positions on both sides of the above-described electronic device, In addition, it satisfies any location where the user can easily operate the electronic device.

For example, when the above-described electronic device is a mobile phone, the electronic device may be installed at both sides of a hinge portion that rotates and opens a folder type mobile phone divided into a main body 1 and a main body 2.

On the other hand, the above-described processor of the present invention, for example, in the initial contactless state of the aforementioned handle, when the above-described mode switch key is selected as a number, it is switched to the number input mode, the numbers are arranged in sequence according to the dial arrangement of the clock If the mode switch key is selected as Hangul, it will switch to Hangul input mode and recognize that Hangul is arranged in order according to the arrangement of the clock face.

In addition, when the above mode switching key is selected as the Hangul input mode, the above-described processor is arranged in the clockwise direction of the contact state of the handle sensor "a ~ ㅌ", the center is the "offset function and a period ( .) And question marks (?) "Can be recognized and processed in order.

In this case, the center "space function, period (.) And question mark (?)" Moves to the next symbol if it is soft touch, and the processor may recognize the selected symbol if it is hard touch.

When the mode switching key is selected once more in the Korean input mode, the above-described processor is arranged in order along the clockwise direction of the contact state of the handle sensor, and the center is the "offset function and a period (. ) And question marks (?) "Can be recognized and processed in order.

It can also be recognized / processed as question marks (?) "Arranged in order.

In addition, when the mode switch key is selected once more in the alphabet input mode, the above-described processor arranges the contact state of the handle sensor in the order of "n to y" along the clockwise direction, and the center is "z and the space function. (.) "May be recognized / processed as being arranged in order.

On the other hand, when there are two input means described above in the present invention, the above-described processor, for example, when the above mode switching key is selected as the Hangul input mode, the contact state of the handle detection sensor of one side "A ~ ㅌ" It is arranged in order along the direction, and the center is recognized / processed as the "Floating function, period (.), Question mark (?) And exclamation mark (!)" In order, and the contact state of the other handle sensor is "ㅏ". ~ ㅎ "is arranged in order in the clockwise direction, and the center" replace function, period (.), Question mark (?) And exclamation point (!) "In order can also be recognized / processed.

In addition, when the above-described input means are two, when the mode switch key is selected as the alphabet input mode, the above-described processor is arranged in the contact state of the handle detection sensor of one side "a ~ l" in order along the clockwise direction, The center is recognized / processed as "m, a space function, and a question mark (?)" Are arranged in order, and the contact state of the other handle sensor is "n ~ y" arranged in a clockwise order, and the center is " You can also recognize / process z as a space, followed by a period (.) ".

On the other hand, as described above, when there are two input means, the aforementioned processor recognizes and processes the signal input from one input means as an input signal of letters, numbers, and symbols, and the signal input from the other input means is a mode. It can also be recognized by the switch signal.

At this time, the other input means is, for example, the 12 o'clock position in the clockwise direction, the 3 o'clock position in the numeric input mode state, the 6 o'clock and 7 o'clock in the Korean input mode state, the 9 o'clock and 10 o'clock alphabets. The input mode state and the 11 o'clock direction can be selected as the alphabetical capital mode mode, and the above-described processor may recognize the mode change signal of the input means as described above.

On the other hand, when there are three input means described above, one becomes a numeric input means, the other becomes a Korean input means, the other becomes an alphabet input means, or one becomes a number input means and mode switching means. The other two may be character input means.

Furthermore, when the above-mentioned input means are five, one becomes a numeric input means, the other two become Korean input means, and the other two input characters of alphabets or other countries, such as Chinese or Japanese. May be

Here, the recognition processing of the processor according to the 12 directions and the center selection position of the input means as described above can be variously applied according to a preset state, for example, text input according to a language other than the above-described input mode. Mode, other function mode, edit mode and user setting mode can also be expanded as necessary to save the settings.

On the other hand, the above-described mode switching key of the present invention, for example, may be selectively used any one of the input key of the electronic device, it may be configured to include a separate key.

In addition, the above-described confirmation means of the present invention, for example, displays the selection position of the above-described input means and the recognition processing structure of the processor according to the above, the user confirms the recognition processing structure of the above-described processor or practicing the input operation mastery To display them separately.

In this case, the above-mentioned checking means may be, for example, displayed on a display device basically included in the electronic device described above, or may be displayed on a separate auxiliary display device.

An embodiment of the present invention as described above will be described in detail with reference to the accompanying drawings.

First, the present invention, in the input device of the electronic device that requires the input and output of letters / numbers / symbols, as shown in Figures 3 to 5 of the accompanying drawings, the outside of the main body 2 of the electronic device 1 described above At least one input including a handle 11 for pointing each position to divide the circle into 12 at a predetermined position and a center position of the circle, and a handle sensor 12 for detecting a moving course of the aforementioned handle 11. Means (10); A processor 20 for processing a moving course detection signal of a handle input from the handle detection sensor 12 as described above through a previously stored program and logic circuit and transmitting the same to a confirmation means 40 for later review; A mode switching key 30 for switching the selection of the above-described input means 10 so that the above-described processor 20 separates each of letters, numbers, and symbols; Confirmation that the processing signal of the processor 20 which processed the handle detection signal input from the above-described input means 10 and the previously stored letters / numbers / symbols and the movement map of the handle 11 accordingly are displayed separately so that they can be checked. And means 40.

The above-described input means 10 of the present invention configured as described above is a tact switch for inputting a change value of a state of being electrically connected by being connected according to the pressing or position movement operation of the handle 11 to the processor 20 described above.

At this time, the handle 11 of the tact switch as the input means 10 described above is a tact button which can select the direction and the center of dividing the circle into 12 in the initial contactless state, and returns to the initial contactless state after the selection, The handle detection sensor 12 is a contact point in a tact path in 12 directions for conducting an electrical signal by selection of the tact button described above.

In addition, the above-described input means 10 is installed on one side or both sides of the display device 2 of the electronic device 1 described above.

On the other hand, the processor 20 described above, when the mode switch key 30 is switched to the numeric input mode in the initial contactless state of the handle 11 of the above-described input means 10, the number according to the dial arrangement of the clock Is recognized as being arranged in order, and if the mode switch key 30 is selected as Hangul, it is switched to the Hangul input mode to recognize that Hangul consonants and vowels are arranged in order according to the arrangement of the dial. When the switch key 30 is selected as the alphabet, it is set in advance to switch to the alphabet input mode and recognize that the alphabet is arranged in order according to the dial arrangement of the clock.

For example, when the above-described mode switching key 30 is selected as the numeric input mode, the above-described processor 20 has the contact state of the handle sensor 12 as "0 to 9" and "#" "*" as the clock. It is arranged in order according to the arrangement of the dials, and the center is recognized / processed as "input, out" in order.

And exclamation point (!)" In order.

At this time, the center "space function, period (.), Question mark (?) And exclamation point (!)" Moves to the next symbol if it is soft touch, and the processor recognizes that the symbol is selected if it is hard touch.

Here, the soft touch means a short contact and the hard touch means a longer contact state than the soft touch.

In addition, when the mode switching key 20 is selected once more in the Korean input mode, the above-described processor 20 arranges the contact state of the handle sensor 30 in order according to the dial arrangement of the clock. In the center, it recognizes / processes that "space function, period (.), Question mark (?) And exclamation point (!)" Are arranged in order.

On the other hand, the above mode switching key 30 is configured to selectively use any one of the above-described input key of the electronic device 1, or to include a separate key.

On the other hand, the above-described confirmation means 40 is displayed on the display device 2 included basically in the above-described electronic device 1, or displayed on a separate auxiliary display device.

Prior to describing the operation of the present invention as described above, the present invention is applied to a mobile telephone and is described by reference. In a typical mobile telephone, a keypad for data input is provided as 12 keys. It is composed.

For example, the number of keys required to enter a telephone number includes 10 numbers up to "0", "1" ....... '9 "and 12 keys up to special characters such as' #' and '*'. .

And when you want to enter the words of text messages, such as SMS transmission, a total of 26 from 'a' to 'b'. In the case of Hangul, a total of 24 input means are required for 14 letters, including 14 main consonants and 10 vowels.

Thus, if the manufacturer of a portable device provides a means for entering more than 36 individual characters with a particular simple key combination, the portable device may be as fast as inputting data into a computer keyboard. Could be.

Thus, the present invention, as described above, in the case of sensing in a manner of switching in the 'key' movement with respect to the four or eight directions, a total of 13 including the vertical direction of the center point, per one keypad module It is designed to allow the direct assignment of branches.

Therefore, when two such keypad modules are installed, a total of 169 combinations corresponding to 13 x 13 can be assigned letters or function 'keys'.

Next, look at the operation according to the configuration of the above-described embodiment as follows.

First, as shown in FIG. 6, when the handle 11 of the input unit 10 points and selects each direction and the center of dividing the circle into 12, the handle sensor 12 determines the connection state. When detected or connected, and transmits the signal to the processor 20, the processor 20 outputs letters, numbers, symbols, etc. for the signal through the display device.

At this time, if the above-described mode switching key 30 is selected as a number input mode for inputting a number, the selection of the above-described input means 10 and the recognition processing state of the processor 20 are as shown in FIG. 7. .

That is, "0" through "9" are arranged in order corresponding to each time with respect to the 12 o'clock direction of the clock, and "#" and "*" symbols are arranged in the 10 o'clock and 11 o'clock directions, respectively.

Therefore, the user can intuitively associate the number with the time, so that the user can easily select the eyes.

In more detail, for example, if the sensor having a form divided into four or eight directions, numeric keys 0, 3, respectively corresponding to the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock directions of the analog clock, respectively. 6, 9 are arranged, and 1,2,4,5,7,8, #, * are arranged between the above-mentioned numbers in the same manner.

Sensing and operation of the input means 10 is, for example, when the handle 11 is raised up, the handle detection means 12 inputs the corresponding signal to the processor 20, at this time, when the handle 11 is released to the center position While automatically returning, the input of '0' is completed, and the processor 20 recognizes the number "0" corresponding to the 12 o'clock direction of the handle 11 and outputs it through the display device 2.

 Similarly, in the case of 3, 6 and 9, the handle 11 is moved to the right, down and left to sense and return to complete the input.

If you want to input 1, 4, 7, # repeatedly, similar to operating the speed control gear of the car, first move the handle 11 in the up, left, down, right direction and keep it, Rotate clockwise to move step by step in the up-right, right-down, down-right, left-up direction to sense the number and automatically return to complete the input.

On the contrary, in the case of 2, 5, 8, and *, first, the handle 11 is moved to the right, down, left and up and maintained, and rotates counterclockwise to make it look like right-up, down-right and left. -Down, up-left step by step to sense and automatically return to complete the input.

In addition, in the sensing operation by pressing the center portion, the input termination and the originating functions are performed as the soft touch and the hard touch, respectively.

In this way, in the structure of recognizing and inputting the position of the number, the position of the number or the corresponding character is arranged according to the keyboard layout of the familiar analog clock, so that the user can easily track the position of the 'key'. It is possible to input a desired number or character by simply moving the finger up, down, left, right and clockwise and counterclockwise at an angle of approximately 90 degrees without looking at the key.

Of course, even in the case of inputting the Hangul or the alphabet, as shown in the accompanying drawings, Figures 8 and 9, the same as the above-described numeric input, it is just to place the characters to correspond to the arrangement of the number plate of the analog clock to input as in the above procedure What is necessary is just to implement, and also in the case of selecting and inputting only a direction like a game, you may input as shown in FIG.

Looking at another embodiment of the present invention as follows.

First, as shown in FIGS. 11A and 11B, when the above-described input means 10 is two in the present invention, the above-described processor 20 is configured to switch the mode switch key 30 to the Korean input mode. If it is selected, the contact state of the handle sensor 12 on one side is arranged in the order "a ~ ㅌ" in the clockwise direction, the center "with a space function, a period (.), A question mark (?) And an exclamation point (!). "Is recognized / processed as being arranged in order, the contact state of the other handle sensor 12 is arranged in order along the clockwise direction" ㅏ ~ ㅎ ", and the center is" offset function and period (.) And question mark (?) And exclamation point (!) "Are stored in advance so that they are recognized / processed in order.

In addition, when the above-described mode switching key 30 is selected as the alphabet input mode, the above-described processor 20 is arranged in the order of the contact state of "a ~ l" in the clockwise direction of the one side handle sensor 12 In the center, "m and a space function and a question mark (?)" Are recognized and processed in order, and the contact state of the other handle sensor 12 is "n ~ y" arranged in a clockwise order. It stores the settings in advance so that the center is recognized / processed as "z, a space function, and a period (.)" Are arranged in order.

In the present invention of the embodiment, the consonants, vowels and the input of consonants are made very quickly and easily in the Hangul mode, and in the alphabet mode, the usability is greatly improved, such as not having to switch the matrix layer to another alphabet group.

Also look at another embodiment of the present invention.

First, as shown in a and b of FIG. 12, when there are two input means 10, the above-described processor 20 inputs letters / numbers / symbols from a signal input from one input means 10. The signal may be recognized as a signal, and the signal input from the other input unit 10 may be recognized as a mode change signal.

At this time, the other input means 10, for example, 12 o'clock in the clockwise direction is the initial state, 3 o'clock in the numeric input mode state, 6 o'clock and 7 o'clock in the Korean input mode state, 9 o'clock and 10 o'clock. The direction can be selected as the alphabet input mode state, and the 11 o'clock direction as the alphabet uppercase mode state, and the above-described processor 20 recognizes the mode switching signal of the input means 10 as described above, After inputting a number in Korean mode and switching to Korean mode, and entering Korean mode again, the trouble of switching from Korean mode to alphabet mode and alphabet mode to number mode can be eliminated.

In addition, as another embodiment of the present invention as shown in Figure 13, when the above-described input means 10 is three, one of the input means 10 is the numeric input means 10, the other Becomes the Hangul input means 10, the other is to be the alphabet input means.

According to the present invention, the input of letters / numbers / symbols is performed without changing the mode, thereby reducing the input time according to the mode switching, and more intuitively inputting is possible.

In addition, the present invention may be provided with the position of the input means 10 on one side of the above-described display device 2, as shown in Figure 14a) of the accompanying drawings, as shown in b) of FIG. The display device 2 may be provided on both sides with the display device 2 interposed therebetween, and as shown in FIG. 14C, the display device 2 may be provided on both sides of the electronic device 1 described above, for example, on the side of the hinge. .

Here, the recognition processing of the processor 20 according to the selection direction of the 12 directions and the center of the input means 10 as described above of the present invention can be variously changed and applied according to a preset state. In addition to the input mode, other function modes, editing mode, and user setting mode can be expanded as necessary to save the settings.

In addition, as shown in Figure 15, the input means 10 is applied to five, one of which executes the numeric input mode including the numbers 0 ~ 9 and # / *, the other is Hangul a Execute Hangul input mode including ~ / and space /./,/?/ !, and another one include Hangul ㅏ ~ ㅣ and ,, ㅎ and space /./,/?/! To execute the alphabet input mode including the letters a to m and space / ?, and the other to enter the alphabet input mode including the letters n to z and space /. Run

In this case, the alphabet input mode may input a foreign language such as Japanese or Chinese.
