Description

A bilingual stenography keyboard {

The present invention relates to a two-country shorthand keyboard for constructing a shorthand keyboard to perform shorthand in two languages and arranging switching keys for fast language switching between character key groups.

In addition, the present invention relates to a two-country shorthand keyboard in which letter keys in the letter key group are arranged slightly wider as the letter keys are positioned upward, and the letter keys in the letter key group are arranged in a fan shape.

In general, a keyboard for entering letters is divided into a general keyboard and a shorthand keyboard. The general-purpose keyboard is used by most people when connecting to a terminal such as a PC and inputting letters, and the shorthand keyboard is used by those who have been specially trained for faster text input at trials, conferences, seminars and press conferences.

As shown in FIG. 1, a conventional general-purpose keyboard is arranged with a large number of keys, and a key includes a character key for inputting letters and various function keys. One letter key is usually mapped to one letter, and when pressed, the letter to be mapped is input. When pressed together with a function key such as SHIFT, another character mapped with the function key is input. The general-purpose keyboard generally needs to input letters sequentially. For example, to input the word "chair", c, h, a, i, and r must be sequentially entered.

Such general-purpose keyboards have a standardized appearance worldwide. However, each country only has different keyboard layouts for their language, and the composition and mechanism are the same. Therefore, you can input the language of any country using a single keyboard.

In addition, two or more languages are arranged on a keyboard and language switching keys are arranged on one general-purpose keyboard, and languages of several countries are input at the same time with one keyboard. In this case, the user may input a language currently being used by switching to another language using a language switch key disposed on the keyboard.

In contrast, the shorthand keyboard uses a separate keyboard for each language.

As shown in Figure 2a, the English shorthand keyboard has 10 keys in two stages of five left and right, and four keys at the bottom. The upper left and right keys are all keys for entering alphabetic consonants, and the lower four keys are key groups for entering vowels.

On the other hand, as shown in Figure 2b, the Korean shorthand keyboard has 10 keys in two stages of five left and right, and has six keys at the bottom. In the same way as the English shorthand keyboard, the upper keys are for entering Korean consonants, and the lower keys are for entering Korean vowels.

Although the keyboard for English and Korean shorthand is slightly different, in general, the keyboard for shorthand is divided into consonant key groups from the left and right in the center, and a vowel key group in the lower center. The left consonant key group is a key for inputting a starting consonant (or consonant), and the right consonant key group is a key for inputting an ending consonant (or final). Assorted key groups are keys that enter a vowel between the beginning and ending consonants. Therefore, you can enter starting consonants, vowels, and ending consonants at the same time.

In addition, the keyboard for shorthand includes only keys corresponding to a part of language letters, and may input the remaining letters by combining limited keys. That is, letters are input by combining two or more keys even within the same key group.

As described above, the shorthand keyboard has a different language between Korean and English, that is, the number of characters, the characteristics of consonants and vowels, and so the character arrangement and mapping rules in the keyboard keyboard are very different. Therefore, the Korean shorthand keyboard is used in a slightly different form from the shorthand keyboard for English. Therefore, it is not possible to input English and Korean at the same time with a shorthand keyboard, and the shorthand keyboard of both languages must be used separately.

Therefore, even if a shorthand can shorten both languages in an international conference where two or more languages such as English and Korean are commonly used, the shorthand has a inconvenience of carrying two shorthand keyboards.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems described above, and to configure a shorthand keyboard to perform shorthand in two languages, and to arrange a switching key for fast language switching between character key groups. It is to provide a combined shorthand keyboard.

It is also an object of the present invention to provide a two-letter shorthand keyboard that arranges the letter keys in the letter key group slightly wider as the letter keys are positioned upward, so that the letter keys in the letter key group are arranged in a fan shape. will be.

In order to achieve the above object, the present invention provides a first letter key group in which a consonant key is arranged at a left side of a center, a second letter key group in which a consonant key is arranged at a right side of a center, and a third letter in which a vowel key is arranged at a center bottom. A keyboard top panel including a key group and a switching key arranged between the first and second character key groups, wherein the consonant key or a vowel key comprises a bilingual character; A key input circuit unit for generating a key signal when the key is pressed; And receiving a key signal or a key signal generated at least two simultaneously, and outputting a signal of one letter or a series of letters corresponding to the key signal set, wherein the letters are output as signals of a letter of one of two countries. And an input key mapping unit, and when the switch key signal is generated, the input key mapping unit converts the key signal generated at the same time or after the signal generation into a signal of a letter of another country and outputs the signal.

The present invention also provides a two-letter shorthand keyboard, wherein the first and second letter key groups are arranged to be spaced apart from each other in the center of the keyboard, and the switching key is arranged between the first and second letter key groups. It is characterized by.

In addition, the present invention is a two-letter shorthand keyboard, wherein the first and second letter key groups in the keyboard top plate is inclined so as to be spaced from each other at the lower end and narrowed at the upper end with respect to the center line are arranged symmetrically with each other. do.

In addition, the present invention is characterized in that in the two-letter shorthand keyboard, the switching key is arranged between the lower end of the first and second character key group.

In addition, the present invention is a keyboard for bilingual dual use, characterized in that the switch key has a triangular shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In addition, in describing this invention, the same code | symbol is attached | subjected and the repeated description is abbreviate | omitted.

First, the key arrangement of the dual-language shorthand keyboard according to the first embodiment of the present invention will be described with reference to FIG. 3A. In the following, two languages will be described using English and Korean as examples. However, any other two languages can be applied.

As shown in FIG. 3A, the dual-language shorthand keyboard according to an embodiment of the present invention includes a first and second letter key groups 31 and 32 in which letters of a consonant are written, and a third letter in a vowel. It consists of a character key group 33 and a function key group 34. At this time, consonants or vowels are represented by pairs of consonants and vowels of two languages. For example, in FIG. 3A, letters "K", "T", "N", and "ㅋ" are displayed in correspondence with one key in a pair of letters of different languages (English and Korean), respectively. .

The first and second letter key groups 31 and 32 in which the consonants are marked are arranged in duplicate from left to right at the center of the keyboard. That is, the letter key group in which the letters of the consonants are marked is divided into a first letter key group 31 located on the left side of the center of the keyboard and a second letter key group 32 located on the right side. The first letter key group 31 includes keys 35 for entering initial consonants or initials, and the second letter key group 32 for entering final consonants or final consonants. Keys 35. A character key group (hereinafter referred to as a third character key group) 33 in which letters of a vowel are written is arranged at the lower ends of the first and second character key groups 31 and 32, that is, at the center lower part of the keyboard.

As shown in Fig. 3A, the first and second character key groups 31 and 32 are each composed of keys of an array of 3x5. That is, there are three rows (or stages) and five columns. As another embodiment, it may consist of keys in an array of 2x5. Numeric keys are arranged directly above the first and second character key groups 31 and 32. Therefore, there are 10 numeric keys. Hereinafter, when referring to the columns of the first and second character key groups 31 and 32, the numbers indicated on the numeric keys corresponding to the columns will be referred to.

The keys of the first and second character key groups 31 and 32 and the fingers pressing the same are the same as those of a general general keyboard. That is, 4, 5, 6, and 7 columns are input by the index finger, respectively, and the keys of the columns corresponding to 3 (or 8), 2 (or 9), and 1 (or 0) are respectively applied to the middle finger, ring finger, and little finger. Pressed by.

The first and second character key groups 31 and 32 are arranged to be spaced apart from each other at the lower stage. Preferably, the first and second character key groups 31 and 32 are inclined and symmetrically arranged so as to be spaced from each other at the lower end and narrowed to each other at the upper end with respect to the center line.

The reason why the first and second character key groups 31 and 32 are arranged symmetrically and obliquely is as follows. The arrangement of the first and second character key groups 31 and 32 is the same as the shape of both hands that are narrowly attached to the upper part and the lower part is slightly open when both hands are placed on the keyboard upper plate 41. In other words, since both hands of a keyboard user are not parallel to each other, the angle of both hands is about 25 ° considering the width of the shoulders and the width of the keyboard. It is.

On the other hand, a switching key 37 is arranged between the lower ends of the first and second character key groups 31 and 32. That is, the switching key 37 is disposed between the gaps formed at the last stages of the first and second character key groups 31 and 32. The switch key 37 is a key operated in a toggle manner as an input key for switching between Korean and English. For example, while the user is inputting Hangul using the shorthand keyboard 30, the switching key 37 is automatically switched to a state of inputting letters in English by simultaneously pressing the switching key 37 with the English alphabet.

The switching key 37 is disposed between the last lower ends of the first and second character key groups 31 and 32 for the following reasons.

Since the shorthand keyboard presses several keys at the same time, most of the hands remain on the keys on the character key group. Therefore, in order to make a quick switch between languages, it is preferable to arrange the switch key 37 on the character key group.

In particular, it is preferable that the switching key 37 be able to use the index finger in addition to the thumb. In the shorthand keyboard, the thumb is usually a vowel key, and there are many double vowels or vowel combinations in the vowel, so both thumbs are most likely used. Therefore, in such a case, it is preferable that the index finger is placed at a position where it can be pressed.

As described above, the position where both the thumb and the index finger can be easily pressed is formed between the lower ends of the first and second character key groups 31 and 32. In other words, by arranging the switching key 37 in this portion, there is an advantage that the space can be utilized at the same time while ergonomically separating the lower ends of the first and second character key groups 31 and 32.

Further, the character keys in each group of the first or second character key groups 31 and 32 are arranged slightly wider toward the top in a fan shape. That is, between the character keys in one character key group are arranged slightly wider as the corresponding character key is located above. As shown in FIG. 3A or FIG. 3B, the columns of the letter keys in one letter key group are arranged to have an angle Q. FIG.

This is because the first letter key group 31 is pressed by the fingers of the left hand and the second letter key group 32 is pressed by the fingers of the right hand in the keyboard top board. At this time, spread out your finger to press the letter keys (C, P, R, Y, M or V, X, B, F, L) located at the top of the group, and the letter keys (B, K, F) located at the bottom. Pinch your fingers to enter, W, N or J, N, D, M, Z). Accordingly, by widening between the letter keys located at the top and narrowing between the letter keys located at the bottom, the user can easily enter letters without straining the wrist or finger.

On the other hand, the third character key group 33 is composed of all six keys. As shown in FIG. 3A, six keys 35 are arranged at the lower ends of the first and second character key groups 31 and 32, three from each other. The vowel key 35 is pressed by the thumb. As another example, the number of keys can be modified differently.

In the third character key group 33, vowel keys are arranged separately on both sides of the center. Ergonomically arranging the first and second character key groups 31 and 32 inclined and spaced apart from the lower end, it is preferable to separate the third character key group 33 to both. Therefore, the third character key group 33 is arranged in both directions. At this time, it is preferable that the special key 38 is arranged between the opened vowel keys.

Generally speaking, English alphabet letters are composed of "consonants + vowels", "consonants + vowels + consonants", and "vowels + consonants" in terms of pronunciation. Accordingly, the first letter key group 31 is keys 35 for inputting consonants that appear before the vowels, and the second letter key group 32 is keys 35 for inputting consonants after the vowels. The middle vowel is input by the third character key group 33.

Two or more keys 35 belonging to the three character key groups may be simultaneously input. That is, the first character key group 31 + the third character key group 33, the first character key group 31 + the third character key group 33 + the second character key group 32, and the third character The key group 33 + the second character key group 32 and the first character key group 31 + the second character key group 32 may be input.

When input at the same time, the input order is a key 35 belonging to the first character key group 31, a key 35 belonging to the third character key group 33, and a key 35 belonging to the second character key group 32. It is decided in order of).

In addition, two or more keys 35 belonging to one character key group may be simultaneously pressed and input. For example, the keys "s" and "t" belonging to the left character key group 31 can be pressed at the same time.

On the other hand, the keyboard top plate 41 further includes a function key group 34 in which function keys are arranged on both top and left and right ends of the character key group. As shown in FIG. 3A, function keys are arranged on the upper ends of the first and second character key groups, and special keys or function keys used in a general-purpose keyboard are arranged on left and right sides.

Next, a key arrangement of the dual country shorthand keyboard according to the second embodiment of the present invention will be described with reference to FIG. 3B. Only parts different from the shorthand keyboard 30 according to the first embodiment will be described below.

As shown in FIG. 3B, the first and second character key groups 31 and 32 are arranged to be spaced apart from each other in the middle of the keyboard top panel, and the switching key 37 is formed by the first and second character key groups 31 and 32. Arrange between. In particular, the switching key 37 has a triangular shape.

Next, the key arrangement of the dual-language shorthand keyboard according to the third embodiment of the present invention will be described with reference to FIG. 3C. Only parts different from the shorthand keyboard 30 according to the first embodiment will be described below.

As shown in FIG. 3C, all the keys of the first and second character key groups 31 and 32 are arranged in parallel, and the first and second character key groups 31 and 32 are spaced apart by one key. . Then, the switching key 37 is disposed between spaced lower ends of the first and second character key groups 31 and 32.

In particular, the switching keys 37 are arranged so as to be arranged over all or at least two ends of the keys of the first and second character key groups 31 and 32.

Next, a configuration of a shorthand keyboard for simultaneously inputting multiple letters according to an embodiment of the present invention will be described with reference to FIG. 4.

As shown in FIG. 4, the shorthand keyboard 30 for simultaneously inputting a plurality of letters according to an embodiment of the present invention includes a keyboard upper plate 41, a key input circuit unit 42, an input key mapping unit 43, and a PC connection. And terminal 44.

The key arrangement of the keyboard top plate 41 is as described above.

The key input circuit section 42 generates a key signal when the key is pressed.

The key input circuit section 42 uses a key scan circuit of a general or shorthand keyboard. Therefore, detailed description is omitted.

The input key mapping unit 43 receives one or more simultaneously generated key signals and outputs a signal for one letter or a series of letters corresponding to the key signals. Preferably, the input key mapping unit 43 includes a memory that stores a mapping rule for searching for a letter corresponding to an input key signal.

In particular, the mapping rules are divided into rules for at least two languages (eg, English and Korean). When the currently input language state is English, the input key mapping unit 43 finds a letter corresponding to the input key signal in the mapping rule for English, and outputs the English letter as a signal. If the current input state is Hangul, Hangul characters are output as a signal from the mapping rule for Hangul.

At this time, the state of the currently input language is switched by the switch key 37. That is, when the switch key signal is generated, the input key mapping unit 43 converts the key signal generated at the same time or after the signal generation into a signal of a letter of another country and outputs the signal.

The switch key 37 may be pressed alone or in combination with other character keys. When pressed alone, the input language is switched to another language as in a general general keyboard. If the current input state is English, it is converted to Korean. The keys pressed after that are mapped by the mapping rules of the converted language and output the letters of that language.

When the switch key 37 is pressed together with another character key, the switch is simultaneously switched to another language and then output as a character of the corresponding language. Shorthand should be typed very quickly at the speed of speech, so language switching should be very fast. Thus, the switching key 37 can also be pressed simultaneously with other character keys and it is desirable to switch to another language from the moment of the pressing.

For example, in FIG. 3, it is assumed that shorthand is currently being performed in English. At this time, when the "H" key of the first character key group, the "N" key of the second character key group, and the "A" key of the third character key group are pressed at the same time, the input key mapping unit 43 returns "han". Outputs a series of English letter signals. However, when the keys and the switching key 37 are pressed at the same time, the input key mapping unit 43 switches from English to Korean and outputs a series of Korean letter signals called "angle".

The derived character signal is input to a computer terminal such as a PC via the PC connection terminal 44. PC connection terminal 44 connects the character signal to the PC. The PC connection terminal uses a method of connecting a keyboard to a conventional computer terminal. For example, the PC connection terminal may be implemented by PS2, USB, or wireless. Since such a technique is well known, a detailed description thereof will be omitted.

Next, the mapping rule stored in the input key mapping unit 43 according to the present invention will be described in more detail with reference to FIG. 5. FIG. 5A is a table illustrating mapping rules for English shorthand, and FIG. 5B illustrates mapping rules for Korean shorthand.

First, the mapping rule for inputting the English shorthand will be described.

The alphabet letters a, b, c, d, and e of FIG. 5A are input by inputting one key. That is, it is input by one stroke. Further, "me" is a word composed of two alphabets, or is simultaneously input by pressing the key of the first letter key group and the key of the third letter key group at the same time. In addition, "she" is a word composed of three alphabets, or by pressing two keys of the first letter key group and one key of the third letter key group at the same time.

On the other hand, frequently used words may have mapping rules by abbreviations. For example, "service" is an abbreviation and has a rule consisting of the first character key group "sr" + the second character key group "vs". Therefore, the user may input "service" by simultaneously pressing the first character key group "sr" and the second character key group "vs". In the same way, those of, whichever, etc. can also be input in only one stroke by simultaneously pressing "th" + "o" + "f", "wh" + "i" + "v", and the like.

On the other hand, when each word is entered by the mapping rule, the spacing is automatically entered. For example, if you hit "sh" + "e" and "sr" + "vr" two consecutively, "she service" is automatically entered.

Next, a mapping rule for inputting Korean shorthand will be described.

The Hangul characters of "A", "I", "D", and "Dang" in FIG. 5B include one key of the first character key group and one key of the third character key group, or a second character key group. By simultaneously pressing one of the keys, one key is input. In other words, the Hangul characters of Chinese characters are input by simultaneously pressing "ㄱ" + "ㅏ", "ㄴ" + "ㅏ", "ㄷ" + "ㅏ", and "ㄷ" + "ㅏ" + "ㅇ" respectively.

Also, frequently used words may have mapping rules by abbreviations. For example, "Seoul" is an abbreviation and has a rule consisting of the first letter key group "ㅅ" + the second letter key group "ㅇㄹ". Therefore, the user can input "Seoul" by simultaneously pressing the first character key group "ㅅ" and the second character key group "ㅇㄹ". In the same way, the Republic of Korea, programs, etc. can also be entered in only one stroke by simultaneously pressing "ㄷㅎ" + "ㅁㄱ", "ㄷㄹ" + "ㄱㄹ" and the like.

 Next, an example of inputting a sentence in which words of two countries are mixed according to an embodiment of the present invention will be described with reference to FIG. 6.

As shown in Figure 6, using the two-language shorthand keyboard according to the present invention, a sentence of "I made a program."

That is, in the first stroke, " p (b) " + " u (ㅏ) " + " xr (ㄴㅇ) " At this time, the state of the input language is the Hangul shorthand input state. In the second stroke, enter "pr (ㄴㅎ)" + "gm (ㄷㄷ)" at the same time and press the conversion key at the same time. From the time when the conversion key is input, the state of the language changes to another language. From the time when the conversion key is input, the English shorthand input state is entered, and from this time, it is input according to the English shorthand mapping rule. In other words, "pr (ㄴ)" + "gm (ㄷ)" is input, but "program" is input by the English mapping rule.

Next, when the conversion key is pressed again at the same time as the input of "s (ㄹ)", it is converted to the Korean input mode again, and the key of "s (ㄹ)" corresponds to the Hangul mapping rule and is mapped to "". And, if you input "dty (ㅁㄷㄹ)" + "ryg (ㅇ ㅆㄷ)", and then corresponds to the Hangul mapping rules, it is mapped to the phrase "made".

Next, pressing the conversion key at the same time with "i (ㅣ)" + "md (方 ㅌ)" applies the English mapping rule. Therefore, it is mapped to "I made" corresponding to "i" + "md". From then on, the English mapping rule will continue to apply. Therefore, when "pr (ㄴㅎ)" + "gm (ㄷ)" is input, "pr" + "gm" is input and interpreted as "program" (mapping).

Therefore, you can switch between English and Korean shorthand very quickly by pressing the conversion key at the same time.

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the Example, this invention is not limited to an Example and can be variously changed in the range which does not deviate from the summary.

The present invention is applicable to the development of a two-language shorthand keyboard that configures a shorthand keyboard to perform shorthand in two languages and arranges switching keys for fast language switching between character key groups.
