The printing mechanism PM, and the display mechanism D are connected to an input/output interface 29 of the controller C. Since the document which is inputted and edited and is stored in a text memory 51 is printed while being subjected to spelling check of each word included in the document and misspelled words are displayed on the display device 27, the spelling check processing is performed only once in the last stage of document printing and misspelled words are collectively corrected at a time. Thus, the time and the labor required for the spelling check processing are reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a printing device with a spell check function, and particularly to one that prints an already inputted document while checking the spelling.

[Prior art]

Generally, some English word processors are equipped with a dictionary memory and a spell check control program in their control device, and are configured to check the spelling of each word included in document data that has already been input.

For example, by setting the spell check mode,
Each word of the document data stored in the text memory is read out in sequence and compared with word data in the dictionary memory. A word processor has been proposed in which, when a misspelled word is detected, the word is displayed on a display device in a display format different from that of words in other document data.

[Problem to be solved by the invention]

However, in conventional word processors, spell check processing and printing processing are completely different processes.
When attempting to print document data without misspelled words on printing paper, it is necessary to spell-check the inputted document data in advance and complete the editing process before starting the printing operation. That is, spell checking had to be performed every time editing was performed.

An object of the present invention is to provide a printing device with a spell check function that can reduce the time and labor of spell check processing as much as possible by performing a printing operation while checking spelling when printing document data stored in a storage means. Our goal is to provide the following.

[Means to solve the problem]

In the printing device, when a printing command is received from the input means, the data of each word in the storage means is read out one after another, the spelling check means is made to check the spelling, and while the data of the correctly spelled word is supplied to the printing means, the data of the misspelled word is It is provided with output control means for supplying word data to the display means.

[Effect]

In the printing device with a spell check function according to the present invention, when the output control means receives a printing command from the input means,
Each word of the document data stored in the storage means is sequentially read out and the spelling check means is sequentially checked for spelling, and as a result of the spell checking, for words with correct spelling, the word data is supplied to the printing means, and for misspelled words, the word data is supplied to the printing means. supplies the word data to the display means. Therefore, the printing means sequentially prints correctly spelled words on the printing medium, and when a misspelled word is detected, the printing operation is stopped, and the display means displays the misspelled word.

At this time, the re-entered corrected word can be printed in place of the misspelled word.

〔Effect of the invention〕

According to the printing device with a spell check function according to the present invention, as explained above, since the output control means is provided, the spell check is performed only once at the final stage of printing the document stored in the storage means. The time and effort spent on spell checking can be reduced as much as possible.

It has a general configuration including a solenoid 26 and the like.

Next, the overall configuration of the control system of the electronic typewriter I will be explained based on the block diagram of FIG.

The electronic typewriter 1 basically consists of a keyboard 3, a printing mechanism PM, a display mechanism, a control device C, etc. The keyboard 3, printing mechanism PM, and display mechanism are connected to an input/output interface 29 of the control device C. ing.

The display mechanism includes a liquid crystal display 27 and a display RAM for outputting display data to the liquid crystal display 27.
It has a general configuration including a display controller 28 including a character generator ROM (CGROM) storing a large number of dot patterns such as characters and symbols.

The control device C includes a CPU 31, an input/output interface 29 connected to the CPU 31 via a bus 30 such as a data bus, a ROM 40, and a RAM 50.

The program memory 41 of the ROM 40 includes the keyboard 3.
The printing mechanism PM corresponds to the code data input from
A control program for controlling the display mechanism, a control program for controlling print processing for printing document data in the text memory 51, and the like are stored. This print processing control program includes a spell check processing control subroutine that checks the spelling of word data read from the text memory 51 based on each word data in the dictionary memory 42, and a spell check processing control subroutine that checks the spelling of word data read from the text memory 51 based on each word data in the dictionary memory 42; A candidate word search control program to be searched is stored. Note that this spell check processing control and candidate word search control are similar to existing ones, so detailed explanation thereof will be omitted.

In the dictionary memory 42 of the ROM 40, data regarding approximately 70,000 words, for example, is stored in alphabetical order similar to a normal dictionary, in order to check the spelling of words.

The RAM 50 includes a text memory 51 that stores input data as document data, a text pointer 52 that stores one address in the text memory 51, and a text pointer 52 that temporarily stores target word data to be read and spell checked. Word data memory 5 to store
3. A correction word data memory 54 for storing input correction word data is provided.

Next, a print processing control routine performed by the control device C of the electronic typewriter 1 will be explained based on the flowchart shown in FIG. In addition, in the figure, Si (i=1.2.
3...) are each step.

After selecting a document by operating the print key 16, press the execution key 13.
This control is started by the operation of , and the start address of the first word data of the selected document data is stored in the text pointer 52 (810 to 5ll), and the text continues until a word delimiter code such as a space code is detected. By sequentially incrementing the pointer 52, word data is output one after another and stored in the word data memory 53 (S1
2). Next, a spell check is performed on the target word data in the word data memory 53 based on the data in the dictionary memory 42, and as a result, if the spelling is too strong, (813 to 5
14) This target word data is printed on printing paper (S15). Note that after printing the target word data, the delimiter code and the like following the target word data in the document data are also printed at the same time. Then, the start address of the next word data is stored in the text pointer 52 (S16
to 517), SL2 and subsequent steps are repeated to sequentially print correctly spelled words.

When the target word is detected as a misspelled word as a result of the spell check (314), the printing process is interrupted, and the misspelled word corresponding to the misspelled word data is displayed on the display 27 (318).
. In this case, the misspelled word is displayed toward the left end of the display 27, for example. Then, it waits for the operator's key power (S19).

Here, when the end key 14 is operated (320)
, terminate this control and return.

Further, when the code key 15 and the character rcJ key 10 are operated at the same time (S21), the misspelled word data, that is, the target word data in the word data memory 53 is a proper noun, etc., and the spelling is correct, so it is printed as is. (S22・515).

When the code key 15 and the number "1" key 10 are operated at the same time (S23), when a character string (corrected word) is input from the keyboard 3, the corrected word is stored in the corrected word data memory 54 and at the same time is displayed on the display. 27 (S24), and when the return key 12 is operated, the corrected word data is printed (S25/515).
). Further, when the code key 15 and the number "2" key 10 are operated at the same time (S26), the character string (corrected word) inputted from the keyboard 3 is stored in the corrected word data memory 54 and at the same time is displayed on the display 27. is displayed (S27), and when the return key 12 is operated, the target word data is erased from the address indicated by the text pointer 52 in the text memory 51 based on the target word data, the corrected word data, and the data of the text pointer 52. and the corrected word data is stored in insert mode (
S28), the corrected word data is printed (S25)
515).

Further, when the code key 15 and the number "3" key 10 are operated at the same time (S29), the candidate word search control program stores the misspelled word in the dictionary memory 42.
data is searched, candidate words are displayed from the center to the right end of the display 27 (330), and the desired candidate word is selected by operating the number keys 10 corresponding to the display order starting from the first candidate word. When selected (331), the candidate word data is printed as corrected word data through step 328 (S25, 515).

As explained above, a document that has been input and edited and stored in the text memory 51 is printed while checking the spelling of each word contained in the document, and misspelled words are displayed on the display 27. Spell check processing is performed only once at the final stage of printing, and misspelled words are corrected all at once, making it possible to reduce the time and effort spent on spell check processing as much as possible.

Incidentally, the detected misspelled word and the corrected word may be stored in association with each other, and when the same misspelled word as the previous one is detected, the corrected word related to the misspelled word may be displayed on the display 27.

It goes without saying that the present invention can also be applied to electronic typewriters equipped with various types of printers such as thermal printers.
