200: right hand key group

The present invention provides a backspace function including a backspace key for erasing all of the shorthand letters and shorthand sentences that are incorrectly inputted during shorthand on either side of the shorthand key group and the right hand key group of the shorthand keyboard. It is about a shorthand keyboard.

As shorthand using a computer has become popular, various shorthand keyboards are being developed. Shorthand keyboards, unlike typical computer keyboards, have a special keyboard layout and fewer keyswitches. Important considerations in the design of shorthand keyboards include high typing speeds, low error rates, low noise, and low fatigue. To best accommodate these issues, most shorthand keyboards have unique keyboard layouts and ergonomic designs. Shorthand keyboards are used primarily by professionally trained shorthands rather than by the general public, so keyboard layouts can be arbitrarily altered for speed. Of course, educational efficiency and ease of use should be considered.

In order to solve these problems, the 'shorthand combined keyboard' of Korean Patent Registration No. 20-0212369 (filed November 21, 2000), and the Korean Registered Patent Publication No. 10-0341969 (filed December 1999) 'Shorthand keyboard' of 14th) was presented.

However, these shorthand keyboards consist of pressing a direction key to designate a typo character and a neighboring character as a block when a typo occurs during shorthand work, and pressing a cancel button to erase a typo character and a character located later.

Because of this, the shorthand work must be completed for a short time, so the time for correcting a typo is insufficient, and the next shorthand work must be carried out immediately without correcting the typo part. .

The present invention has been devised to solve the above problems, the backspace for erasing the entire shorthand letter and shorthand sentence at the same time in the shorthand in the shorthand key of the left hand key group and the right hand key group of the shorthand keyboard The purpose is to provide a shorthand keyboard comprising a key.

Shorthand keyboard with a backspace function according to the present invention to achieve the above object,

A character key group 10 consisting of a left hand key group and a right hand key group for inputting characters into a case consisting of primary, neutral, and final keys is centrally disposed in the center of the case, and a function key group 20 for executing various functions is provided. It consists of a shorthand keyboard arranged and arranged around the character key group 10,

The left hand key group and the right hand key group are formed on any one of the initial, neutral, and the final key is formed by including a backspace key that erases the entire shorthand letters and shorthand sentences at once.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Also, as shown in FIG. 2, the backspace key may be configured at one side of the second numeric key button '0' of the right-hand key group and at one side of the lower side of the bottom of the final support.

Hereinafter, the process of sending data from the backspace key to the main body will be described. In the normal state, as shown in FIG. 3, both the CLK and DATA pins are in a high state (+ 5V). When it is in this high state, it sends information of backspace pressed to the main body. However, if you set the CLK pin low (0V) on the main unit, the keyboard will determine what it is doing on the main unit and no longer send data. The information of the pressed backspace key is temporarily stored in the buffer.

Data is sequentially transmitted one bit at a time on the DATA pin, and a periodic Perth is applied to the CLK pin at the data rate to distinguish each data bit. Once the CLK pin is clocked, it transmits keyboard data one bit at a time. If the CLK signal falls low by the main body before the transmission of one byte of data is completed, the transmitted data is interrupted.

The data on the backspace key transferred to the main body through the DATA pin is transferred to the microprocessor (MCU).

Hereinafter, as shown in FIG. 4, the abbreviation input mode and the function key input (backspace key input) are checked in the microprocessor (MCU) to perform abbreviated input, abbreviated search, and delete events in parallel. Let's explain.

First, the key input state is checked (S100).

That is, when the key input is the abbreviation input mode, the abbreviation correction and additional input of the database are performed (S110 to S111).

Subsequently, a buffer of multiple array delete characters (delete_count) is initialized (S112).

If the key input is not the abbreviated input mode, it is checked whether a function key is input (S120).

When the function key (Function) is input, it is checked whether the backspace key of the function key is input (S130).

When the backspace key is input, the backspace event is output from the key buffer as many times as the deleted_count in the order stored in the buffer, and the buffer is initialized by specifying the deleted multiplex character as 0 (S131 ~ S132). )

Here, the backspace event deletes all of the shorthand characters and shorthand sentences that are incorrectly inputted by the number of delete arrays (delete_count) stored in the buffer, in addition to the function of deleting only the first character used for the existing general keyboard. This is added and progressed.

If the backspace key is not input, another function key is activated, and the buffer is initialized by setting the number of multi-array deletion characters to 0 (S133 to S134).

Then, if the key input is not a function key input, check whether the primary key of the completed code is entered. If the primary key of the completed code is input, find the primary key of the completed code in the database and output it to the key buffer. The shorthand operation is performed (S140, S190).

Here, the basic key of the completed code is a letter completed through the left hand key group and the right hand key group consisting of the initial + neutral + final key, or the initial + neutral key. For example, "special", "ga", "han", " Choi "... etc. can be mentioned.

Subsequently, if the primary key of the completion type code is not input to the key, the next step is to check whether a word has been input, and if a word is input, find a corresponding word in a database and output it to a key buffer to perform a shorthand operation (S150, S190).

Here, a word is a minimum unit of a word having a certain meaning in grammar, and refers to a linguistic unit having a meaning composed of one or two phonemes by combining primary keys of the completed code.

Subsequently, if a word is not input at the time of key input, after checking whether the utilization type is input, if the utilization type is input, the corresponding word is found in the database and output to the key buffer to perform a shorthand operation (S160 and S190).

Here, the utilization type is registered as an abbreviation of a combination of primary key + number, word + alphabet, number + alphabet of the completion type code, for example, if the primary key + number, word + alphabet, number + alphabet of the completed type code is entered, " "," "Speaks", "speaks", etc. will be output directly to the key buffer.

Subsequently, when a key corresponding to the basic key, word, and utilization type of the completed code is not input at the time of key input, the microprocessor (MCU) recognizes a typo, outputs a typo value to the key buffer, and counts the total number of typos. The multi-array delete character count (delete_count) is stored in the buffer to proceed with the delete event (S170 to S180).

Hereinafter, a process of setting a multi-array delete character count (delete_count) by searching for a corresponding letter in a database through the primary key, word, and utilization type of the completed type code will be described.

This means that if a typo occurs among shorthand letters and shorthand sentences composed of basic keys, words, and conjugations of the completed code, which is an input key, the microprocessor (MCU) deletes all the immediately preceding shorthand letters and shorthand sentences. For example, the number of typos is calculated and stored in the delete_count buffer, and the delete event proceeds as much as the delete_count value.

First, check whether the character to find is one letter, and if it is one letter, the number of deleted characters (delete_count) is calculated as the number of initial + neutral + final and initial + neutral, and the calculated number of deleted characters ( delete_count) is stored in the order in which the buffer is entered, and the delete event proceeds as much as the value stored in the delete_count buffer (S191 to S192 and S196).

The search letter is a single letter refers to a primary key of a completed type code that is a letter completed through the left hand key group and the right hand key group consisting of the primary, neutral, and final keys.

For example, the word "Well", which is a single letter, is a superlative letter 'c' (1), a neutral 'ㅏ' (1), and a final letter 'ㄲ' (1). It is specified as and stored in the buffer. In addition, the delete event proceeds as much as the initial constellation '인' (1), the neutral 'ㅏ' (1), and the finality 'ㄲ' (1), which are values stored in the multi-array delete character count (delete_count) buffer.

Then, if the letter you are looking for is not one letter, check whether the last letter of the next letter is Hangul, and if the end letter is Korean, subtract 1 from the total number of letters (including offset) , Add this to the number of initial, neutral, and final characters of the end character, and store the calculated number in the order in which they are entered in the delete_count buffer, and store in the delete_count buffer. The delete event proceeds as much as the stored values (S193 to S194, S196).

The end letter of the searched letters is Hangul means words, phrases, sentences, etc. that do not include English letters or special characters in the suffix.

For example, "I'm going to school," the last letter of the searched letters, for example, after subtracting 1 from the total number of letters (including spaces) 17, here is the initial letter '다' 18) plus 2, the neutral 'ㅏ' (1), is stored in the buffer as the number of multiple array delete characters (delete_count). Then, the delete event is processed by the number of characters 18, which is a value stored in the multi-array delete character count (delete_count) buffer.

Here, the number of 18 characters includes a cursor indicating the beginning of the delete character as shown in Table 1, which is not included in the microprocessor (MCU) after the typo. It is to delete the cursor more precisely by setting the cursor to the position pointer which is the starting point of deletion.

In other words, if the end character is an English character, the alphabet can be deleted by specifying the positional pointer immediately.However, if the end character is Korean, it is composed of initial, neutral, and final characters. Since it is difficult to specify a pointer, the cursor located after the typo is designated as a position pointer.

I Is crane School ( S c h o o l ) on liver All Cursor Total number 18 Characters One One One One One One One One One One One One One One One One One One

Next, if the ending character of the character to be searched is not Hangul, next, the multi-array delete character (delete_count) is calculated as the total number of letters, and the calculated number is stored in the order of entering the multi-array delete character (delete_count) buffer. Then, the delete event proceeds as much as the value stored in the multi-array delete character count (delete_count) buffer (S195 to S196).

If the end letter of the searched letters is not Hangul, then the multi-array delete_count is calculated as the total number of letters, and the total letters such as words, phrases, and sentences including letters or special characters at the end of the sentence are calculated. Refers to a number (including spaces).

For example, the case of "I am going to school." Because the end of the character ends with a "period (.)", It calculates the delete_count of the multi-array delete character (21) as the total number of letters, and enters the calculated total number of 21 characters into the delete_count buffer. In order to store them, the delete event is processed by the number of characters 21 stored in the delete_count buffer.

Here, the number of characters 21 includes a period (.) Indicating the beginning of the delete character as shown in Table 2, because the microprocessor (MCU) has a period, an exclamation point, and a question mark at the back of the typo. The period, exclamation point, question mark, etc. are set to the position pointer which is the starting point of deletion to delete more accurately.

I a m g o i n g t o s c h o o l .  Total number 21 Characters One One One One One One One One One One One One One One One One One One One One One

As another example, consider the case of "George W. Busi".

Since the end character ends with the letter "i", the multi-array delete character (delete_count) is counted as 14, which is the total number of letters, and the calculated total 14 characters in the order of entering the multi-array delete character (delete_count) buffer. After storing, the delete event is processed by the value of 14 characters stored in the delete_count buffer.

Here, the number of characters 14 includes the alphabet letter i indicating the beginning of the deletion character as shown in Table 3, which is more accurately deleted by setting the alphabet letter i, the typo character, as a location pointer as the deletion start point in the microprocessor (MCU). It is for.

Through this process, if there is a shorthand character that is incorrectly input during shorthand input by the shorthand keyboard, the user may delete all of the front shorthand letters and shorthand sentences that are incorrectly input through the backspace key.

The present invention is configured to include a backspace key for erasing the entire shorthand letter and the shorthand sentence in the shorthand as described above at the same time, it is possible to provide a quality service at the time of shorthand work, it is possible to improve work efficiency It has a good effect.
