Description

The present invention relates to a text editing device such as an electronic typewriter having a spell check function.

[Prior Art] Conventionally, as a text editing device of this type, for example, in an electronic typewriter, a word RAM input from a keyboard or the like is stored, and this word is compared with a prepared dictionary memory to spell it. It is known that the error is checked and if a spelling error is detected, a buzzer or the like notifies the error.

In addition, as a function to correct the printed characters, each character of the input word and its position are stored in a storage area called a collection buffer for one line, the carriage is moved based on that, and the collection key is pressed. Delete the printed characters without pressing the key
A device having so-called autocorrection is known.

[Problems to be Solved by the Invention] In the above sentence editing device, when a line feed operation command is issued by the return key or the like in a mode in which a spell check is performed every time a word is input, a line feed is immediately performed. At the same time, the collection buffer was cleared. For this reason, even if there was a misspelled word at the beginning of the line and it was announced, if you forget it and start a new line, the spelling error may remain. Also, even if you notice a spelling mistake in the previous line after the line feed, you cannot correct it by autocorrection, return the print head to the line of the misspelled word, press the manual correction key, and then press the key of the missed character. Had to press and fix. If you press the return key further, the spelling of the word just before you press the return key will be checked, and a line break will occur immediately. Even if you are informed that there is a misspelling in the previous word, you can not do autocorrection. was there.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a sentence editing device that can correct a word having a spelling error reliably, quickly and easily.

[Means for Solving Problems] In order to solve such problems, the text editing apparatus according to the present invention, as shown in FIG. 1, is inputted with a dictionary storage means for storing a large number of words. A collection buffer that stores a line of a character string composed of words, a line feed means that orders a line feed to the character string, and a word in the collection buffer and a word in the dictionary storage means are compared, and a spelling error is made. If there is a comparison detection means for detecting whether there is a spelling error by the comparison detection means,
It is characterized by further comprising line feed stopping means for stopping the line feed operation even if there is a line feed command of the line feed means, and notification means for notifying when the spelling error is detected.

Here, as the line feed means, if the spelling error is not detected by the comparison detection means, a means for executing the line feed operation can be adopted.

Further, as the comparison detecting means, a means for comparing both words based on the line feed command of the line feed means can be adopted.

Further, as the line feed means, when the comparison detecting means detects a spelling error based on the line feed command, a means for executing the line feed operation based on the next line feed command can be adopted.

Further, as the collection buffer, a buffer whose stored contents are not cleared based on the line feed command when a spelling error is detected based on the line feed command of the line feed means can be adopted.

A buzzer, a light emitting diode, or a liquid crystal can be used as the notification means.

[Operation] In the text editing device of the present invention having the above configuration, the dictionary storage means stores a large number of words, and the collection buffer stores a character string of the input words for one line. Then, the comparison / detection means compares the words in the collection buffer with the words in the dictionary storage means to detect whether or not there is a misspelling, and when the comparison / detection means detects a misspelling. Even if there is a line feed instruction by the line feed means for instructing the line feed of the character string, the line feed stop means stops the line feed operation. At the same time, the notification means notifies that the spelling error has been detected.

That is, according to the present invention, a character string consisting of an input word is stored for one line, the spelling of the word is checked, and if a spelling error in one line is detected, even if there is a line feed command, The line feed operation is stopped and the notification means is used.

[Examples] Next, examples of the present invention will be described. The present invention is not limited to these, and includes various embodiments without departing from the scope of the invention. FIG. 2 is a schematic perspective view showing an electronic typewriter 1 which is an embodiment of the text editing apparatus of the present invention, and FIG. 3 is a block diagram showing its electric system.

The electronic typewriter 1 takes in a character string such as a word input from the keyboard 2 into an electronic control unit 3 (see FIG. 3), stores it, and displays it on a liquid crystal panel 4 to store the stored character. The rows are printed on the paper (not shown) mounted on the platen 6 using the daisy wheel 8 at the same time as the input or in response to a predetermined key input.

When performing printing, the electronic typewriter 1 controls the row direction position of the carriage 16 by driving the stepping motor 18 by the electronic control unit 3 and also controls the daisy wheel 8 and the printing hammer 19 mounted on the carriage 16. . The carriage 16 is slidably supported by a guide shaft 20 provided parallel to the platen 6, and is driven in the axial direction of the platen 6 via a toothed belt 22 by the rotation of a stepping motor 18. The daisy wheel 8, which is rotatably mounted in the type cassette 23, places a type character (not shown) at the printing position by the rotation of a character selection stepping motor (not shown). The printed characters are struck by the printing hammer 19, and printing is performed on the paper through the printing ribbon 25 stored in the ribbon cassette 24. The line feed operation is performed by the return key R, the carriage 16 is moved by one character by the space key SP, and the character is erased by the collection key K.

A buzzer 27 is attached to a side portion of the electronic typewriter 1, and a plurality of through holes 29 are provided in corresponding portions of the case 28.

The electronic control unit 3, as shown in FIG.

Control for realizing the above processing is performed.

Next, the process of checking the input word will be described with reference to the flowchart of FIG. First, the user operates the keyboard 2 to input a character string. The input one-line sentence character string is stored in the collection buffer 33a in the RAM 33, and the processing is performed at the same time. First, the presence / absence of key input is determined (step S1)
[Hereinafter, simply represented by step S. The same applies to other steps], and if there is no key input, the process returns to S1 and waits for key input. On the other hand, if there is a key input, it is judged whether or not it is the return key R (S2), and if it is not the return key R, another key processing, for example, storage processing in the memory by operating a character key is performed (S3). ), Return to S1 and wait for the next key input.

On the other hand, in the case of the return key R, it is determined whether or not the return flag F is set (S4). The return flag F determines whether or not the return key R has already been pressed on the same line, and is not set for the first time. If it is determined in S4 that the return flag F is not set, the words in the line being input are sequentially checked for spelling (S5), and it is determined whether there is a misspelling (S5).
6). If a misspelling is detected here, the buzzer 27
Sound (S7), set return flag F (S7)
8) Return to S1 and wait for the next key input. On the other hand, if no spelling error is detected in S6, a line feed operation is performed immediately (S
9), the collection buffer 33a is cleared, the process returns to S1 and waits for the next key input. In S4, the return flag F
If it is determined that is set, that is, if the return key R has already been pressed once, the return flag F
Clear (S10), return to S1 via S9, and wait for the next key input.

The electronic typewriter 1 of the present embodiment configured as described above
The input word is stored in the collection buffer 33a for one line, and a line feed operation command, for example, the return key R is pressed to sequentially check spelling of all the words in the input line. When a spelling error is detected by this check, the buzzer 27 gives a notification, the line feed operation is stopped, and the return key R is pressed again to start a line feed. That is, when a misspelling is detected, the collection buffer 33a is not cleared by the first line feed operation command, so that the word in the line being input can be easily corrected using autocorrection. Furthermore, even if there is a misspelling in the word entered immediately before the return key R is pressed, the line feed will not occur and the correction can be easily performed. In addition to checking the spelling for each line, the spelling may be checked for each word as well. In that case, if the return key R is pressed, if there is a misspelling, the line will not be broken. There is an advantage that you can correct it surely without forgetting to start a line and forgetting the word that was notified of a spelling mistake.

In addition to the sound of the buzzer 27, voice, LED blinking and liquid crystal display may be used as the means for notifying the user, and the carriage 16 may be moved to the position of the wrong character.

Further, in the above embodiment, a line feed occurs when the return key R is pressed twice. However, the line feed may be stopped until the spelling error is corrected, and the line feed may be released by another key. .

Further, as a means for instructing a line feed operation, the return key R
Not only the key, but also a space for several characters at the end of the line.
Define SP, hyphen key H (see Fig. 2), etc.,
You may use it.

[Effects of the Invention] As described in detail above, the text editing device of the present invention stores one line of a character string consisting of an input word, checks the spelling of the word, and checks the spelling in one line. In the case of detecting the line feed, the line feed operation is stopped even if there is a line feed command, and the notifying means notifies, so that an excellent effect that correction can be performed extremely reliably, quickly and easily is achieved.
