Abstract

PURPOSE:To correct spelling mistakes with extremely high accuracy and in a quick and easy way by checking the spelling mistakes of input words for each line. CONSTITUTION:An electronic control device 3 consists of a CPU31, a control ROM32, a readable/writable RAM33, a word checking ROM34, etc. The character strings equivalent to a single sentence inputted from a keyboard 2 are stored in a collection buffer 33a in the RAM33. Then the spelling check is successively given to all words of the line under an input state by an instruction for line feed actions, e.g., an action to push a return key. A spelling mistake if detected is informed by a buzzer 27 and at the same time the line feed action is stopped. Then a return key is pushed again for line feed. In other words, the buffer 33a is not cleared with the first line feed action. Thus an auto-collection system is applied for easy correction of words of the line under an input state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a text editing device such as an electronic typewriter having a spell check function.

[Prior Art] Conventionally, as this type of text editing device, for example, an electronic typewriter, words input from a keyboard etc. are stored in a RAM.
It is known that the word is stored in a dictionary, etc., and this word is compared with a dictionary memory prepared in advance to check for spelling errors.If a spelling error is detected, a buzzer or the like is used to notify the user of the spelling error.

In addition, as a function to correct printed characters, each character and its position of the input word is stored in a storage area called a correction buffer for one line, and the carriage is moved based on this and the correction key is pressed. Erase printed characters without pressing the key for the character to be printed,
A device equipped with so-called auto-correction is known.

[Problems to be Solved by the Invention] In the above-mentioned text editing device, when a command for a line feed operation is issued using the return key etc. during a spell check mode every time a word is input, a line feed is immediately performed. At the same time, the collection buffer was cleared. Therefore, even if you are notified of a misspelled word at the beginning of a line, if you forget it and start a new line,
Spelling errors were often left intact. Also, when you notice a spelling mistake on the previous line after a line break, the autocorrection cannot correct it, and you return the print head to the line containing the misspelled word, press the manual correction key, and then press the key for the misspelled letter. I had to press and fix it. Furthermore, when you press the return key, only the spelling of the word immediately before you press the return key is checked, and a line break is immediately added, so even if you are notified that there is a spelling error in the previous word, autocorrection cannot be performed. was there.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a text editing device that can reliably, quickly, and easily correct misspelled words.

[Means for solving the problem] In order to solve the problem, the present invention provides a dictionary storage means M1 that stores a large number of words, as shown in FIG.
and a line storage means M2 for storing the word of the line being input.
When receiving an instruction to break the line being input, the line storage means M
a comparison detection means M3 that sequentially compares the words in the dictionary storage means M1 with the words in the dictionary storage means M1 to detect spelling errors; and when a spelling error is detected by the comparison detection means M3, the change action is stopped. The present invention is characterized in that it includes a line break stop means M4 for stopping the line feed, and a notification means M5 for notifying when a misspelling is detected. Here, the notification means M5 may be a buzzer, a light emitting diode, or a liquid crystal.

[Operation] The text editing device of the present invention having the above configuration stores one line of input words in the line storage means M2, and when receiving an instruction to break the line being input, it stores a large number of words in advance. The words in the dictionary storage means M1 and the words in the line storage means M2 are sequentially compared and examined by the comparison detection means M3 to check for spelling errors. If a spelling error is detected, the line feed stopping means M4 stops the line feed, and the notifying means M5 notifies the user of the presence or absence of the spelling error.

[Example] Next, the present invention will be explained in detail. The present invention is not limited to these, but includes various embodiments without departing from the gist thereof. FIG. 2 is a schematic perspective view showing an electronic typewriter 1 which is an embodiment of the text editing device of the present invention, and FIG. 3 is a block diagram showing its electrical system.

This electronic typewriter 1 inputs a character string such as a word inputted from a keyboard 2 into an electronic control device 3 (see FIG. 3), stores it and displays it on a liquid crystal panel 4, and displays the stored character strings on a liquid crystal panel 4. A daisy wheel 8 is used to print a column on a sheet (not shown) mounted on a platen 6 at the same time as input or in response to a predetermined keystroke.

When the electronic typewriter 1 prints, the electronic control device 3 controls the position of the carriage 16 in the row direction by driving a stepping motor 18, and also controls the daisy wheel 8 and printing hammer 19 mounted on the carriage 16. do. 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 rotation of the stepping motor 18. The daisy wheel 8, which is rotatably attached to the character cassette 23, places unillustrated characters at printing positions by rotation of a character selection stepping motor (not shown). The printed characters are struck by a printing hammer 19 and printed on the paper via a printing ribbon 25 housed in a ribbon cassette 24.

Further, the movement change operation is performed by using the return key R, etc., the movement of the carriage 16 by one character is performed by the space key SP, and the deletion of characters is performed by the correction key K.

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

As shown in FIG. 3, the electronic control device 3 is a well-known CPU.
31. It is configured as a logic operation circuit from a control ROM 32 that stores control programs and data in advance, a read/write RAM 33, a word check ROM 34 that stores information for checking words that constitute an input character string, etc. ing.

The CPU 31 performs the following input/output processing while temporarily reading and writing necessary data in the RAM 33 according to a procedure (program) stored in the control ROM 32. That is, (1) the process of manually inputting keys from the keyboard 2 via the keyboard input/output circuit 35; (2> the printing drive circuit 3);
6 to drive the stepping motor 18 to control the carriage 16, while controlling the character selection stepping motor and printing hammer 19 to print characters;
3) Displaying characters input from the keyboard 2 and other necessary information on the liquid crystal panel 4 via the panel drive circuit 37; (4) Upon receiving a command to change the character string, check the spelling of the input character string. (5) When a spelling mistake is detected, the process of outputting the result to the output circuit 38 and sounding the buzzer 27; (5) When a spelling mistake is detected, the process of stopping the change action; (6) In the case of a change action, the stepping motor 18 is driven to return the carriage 16 to the home position (left end), and at the same time drives a line feed motor (not shown) to rotate the platen 6 and feed the paper one line.CPtJ31 contains necessary data, etc. are interconnected with the ROM 32, RAM 33, keyboard input/output circuit 35, print drive circuit 36, panel drive circuit 60, output circuit 38, etc. via the bus 41 to perform control for realizing the above processing.

Next, the process for checking input words will be explained using the flowchart shown in FIG. The user first operates the keyboard 2 to input a character string.

The input one-line character string is stored in the collection buffer 33a in the RAM 33, and is processed at the same time. First, determine the presence or absence of key human resources in step S1.
) [Hereinafter, a step will be simply represented by S. The same applies to other steps], if there is no key power, return to Sl again and wait for key power. On the other hand, if there is a key manually, it is determined whether it is the return key R (S2), and if it is not the return key R, other key processing is performed, for example, processing is performed to store it in the memory by operating a character key (33) , return to Sl and wait for the next key manpower.

On the other hand, in the case of return key R, it is determined whether return flag F is set (S4).

This return flag F is used to determine whether the return key R has already been pressed on the same line, and is not set if this is the first time. If it is determined in S4 that the return flag F is not set, the spelling of the words in the line being input is sequentially checked (S5), and the presence or absence of spelling errors is determined (S6). If a spelling mistake is detected here, the buzzer 27 is sounded (S7), a return flag F is set (S8), and the process returns to Sl to wait for the next key input. On the other hand, if no spelling errors are detected in S6,
Immediately perform a change action (S9) and collect collection buffer 1
Clear 33a, return to Sl and wait for the next key manpower. If it is determined in S4 that the return flag F is set, that is, if the turn key R has already been pressed, the return flag F is cleared (S
10>, return to Sl via S9 and wait for the next key manpower.

Electronic typewriter 1 of this embodiment configured as above
The input word is stored in the collection buffer 33a for one line.
, and by pressing a command to change the line, for example, the return key R, spell checking is sequentially performed for all words in the line currently being input. If a spelling error is detected by this check, a buzzer 27 is used to notify the user, the line feed operation is stopped, and the line feed is started by pressing the return key R again. That is, when a spelling error is detected, the correction buffer 33a is not cleared by the first change action, so 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 pressing the return key R, it can be easily corrected since no line breaks are made. Also, in addition to checking the spelling for each line, it may also be configured to check the spelling for each iH, in which case the word for which the misspelling was reported at the beginning of the line is forgotten and the line is broken. It has the advantage of being able to be corrected without fail.

In addition to the sounding of the buzzer 27, the above-mentioned notification means may include sound, blinking of an LED, and display on a liquid crystal.
Furthermore, the carriage 16 may be moved to the position of an incorrect character.

Also, in the above example, pressing the return key R twice causes a line break, but it is also possible to stop the line feed until the spelling mistake is corrected, and then use another key to cancel the line break. .

Furthermore, as a means of commanding a change action, press the return key R.
In addition, you can also use keys such as the space key SP and the hyphen key H (see Figure 2) that automatically start a new line within the so-called hot zone at the end of a line. good.

[Effects of the Invention] As described in detail above, the text editing device of the present invention has the advantage of checking spelling errors in input words line by line, so that corrections can be made extremely reliably, quickly, and easily. It has a great effect.
