Abstract

PURPOSE:To enable interruption of operation corresponding to a delimiter key upon detecting of an error, by checking the spelling of each word on the basis of data stored in a word data memory and data stored in a dictionary memory. CONSTITUTION:Code data corresponding to character symbol keys 4-6 being inputted through a keyboard 3 are printed by means of a print mechanism and simultaneously written into a word memory 110. When word delimiter data stored in a delimiter data memory 104 in ROM53 is inputted, said data is written into a delimiter data memory 118 so as to check the data or words written into the word data memory 110. When the spelling is correct, operation corresponding to the delimiter data is executed. If input and printing of data are continued and an erroneous spelling is detected, an alarm buzzer sounds to interrupt operation corresponding to the delimiter data, or printing of period or comma is stopped. In this case, a correction key 23 is operated to erase the error character and print a correct spelling.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an input processing device equipped with a spell check function, and in particular stops the operation of word separator keys such as return and space when a spelling error is detected. The present invention relates to an input processing device configured to perform.

(Prior Art) Recently, electronically controlled English typewriters are equipped with an input data memory for storing input data and a dictionary memory for storing a large number of words in the control device, and are equipped with an input data memory for storing input data and a dictionary memory for storing a large number of words. Devices equipped with a spell check function that automatically checks spelling by comparing words in dictionary memory are also widely put into practical use.

In typewriter mode, where data input from the keyboard is printed sequentially, if you press a word separator key such as the space key or return key after inputting a word, the space or return action corresponding to the separator key you operated will be displayed. At the same time, a spell check is executed, and if a spelling error is detected for the word, an alarm or the like is generated to notify the operator of the spelling error.

(Problem to be Solved by the Invention) In this type of typewriter equipped with a spell check function, when a spelling error is detected in a word spell checked in typewriter mode, a spelling error corresponding to the operated separator key is detected. Operations such as line feed, return, space feed, tab operations, and printing of characters such as commas and periods have already been performed, so in order to correct the spelling of the word in which an error has been detected, the carriage return (print head) must be moved to the corrected character position.

In the above case, relatively high-end models that remember the printed character position can immediately move the carriage to the corrected character position, but lower-class models do not remember the printed character position, so they can be used, for example, as a separator key to return the carriage. When a key is operated, it is necessary to move the carriage to the position of the corrected character in the previous line using a backspace key, paper return key, etc., resulting in a problem that the operability becomes very poor.

In addition, when a misspelling of a word due to missing characters or unnecessary characters is detected, the printed characters such as commas and periods are also erased by changing the printing position of the characters corresponding to the delimiter keys such as commas and periods. However, there are problems in that the correction work is time consuming and the operability is poor.

(Object of the Invention) An object of the present invention is to provide an input processing device that can stop an operation corresponding to a separator key when a spelling error is detected in a spell-checked word.

(Means for Solving the Problems) As shown in the functional block diagram of FIG. 1, the input processing device according to the present invention includes a keyboard for inputting data such as characters and symbols, and each input word. a word data memory that temporarily stores data of a plurality of words, a dictionary memory that stores data of a plurality of words, and a spell check control that performs a spell check of each word based on the data of the word data memory and the data of the dictionary memory. In the input processing device comprising means, when a spelling error in an input word is detected by the spell check control means, a break operation stop control for stopping processing corresponding to the break data next to the last character data of the word. This means that a means has been established.

(Operation) In the input processing device according to the present invention, data of each word input from the keyboard is temporarily stored in the word data memory.

Then, the spell check control means performs a spell check for each word based on the data stored in the word data memory and the data in the dictionary memory storing a plurality of words.

When the spell check control means detects a spelling error in the input word, the delimiter operation abort control means aborts the process corresponding to the delimiter data next to the last character data of the word.

(Effects of the Invention) According to the input processing device according to the present invention, as explained above, when a spelling error is detected in the spell-checked word, the process corresponding to the delimited data is stopped. In particular, when the delimited data is line feed data or return data, there is no need to move the carriage to the print position of the previous line's correction text using the backspace key or the return key. There is no need to erase the symbol, correction work can be carried out quickly, and operability is improved.

The display controller 52 stores display data for displaying characters, etc. on the display 21 in correspondence with code data of each character or symbol. The display controller 52 outputs display data corresponding to code data input to the display controller 52 to the display 21.

The control device C includes a CPU 46, a ROM (read only memory) 53 connected to the CPU 46, and a RAM (
The keyboard 3, each of the drivers 39, 47 to 51 of the driving means PM, and a display controller 52 are connected to the CPU 46.

The ROM 53 stores character symbol keys 4 and 4 of the keyboard 3.
Each of the motors 25, 31,
34, 43, 45, a control program that controls the print hammer solenoid 38 and the display 21, and a keyboard 3.
Each of the motors 25, 31, 34, 43, 45 corresponds to the code data of each function input from the various function keys of
and a program memory 100 storing a control program for controlling the printing hammer solenoid 38, a spell check control program for spell check processing, a control program for character erasing control, a control program for dividing operation stop control to be described later, and the like. For spell checking, for example, there is a dictionary memory 102 in which data regarding approximately 70,000 words is stored, sorted in alphabetical order like a normal dictionary, and a space, return,
A delimiter data memory 104 is provided that stores code data of word delimiters such as tabs, periods, semicolons, and commas.

The RAM 54 includes a word data memory 110 that stores data of the word currently input for spell checking, and a print data memory 112 that stores printed data in sequence in correspondence with the printing position. A current position memory 114 that stores the current position of the carriage 27 in correspondence with the printing position, a type position memory 116 that stores the current rotation angle position of the type wheel 33, that is, the spoke number of the type 36 at the print position, a space, and a return. A delimited data memory 118 that temporarily stores input delimited data such as , period, semicolon, comma, etc.
There are provided a delimiting operation stop flag memory 120 that is set when the delimiting operation is canceled, and various types of memories that temporarily store the results of arithmetic processing performed by the CPU 46.

The CPU 46 uses character symbol keys 4 and 5 of the keyboard 3.
・The code data corresponding to each character and symbol such as alphabets, numbers, and symbols input from 6 is printed on the printing paper 17 by the printing mechanism, and the word data memory 11
0, and each time a delimiter code such as a space is input, the spell check control program and dictionary memory 102
Spell check calculation processing is performed on the input word based on the data.

Further, the CPU 46 sequentially stores the printed data in the print data memory 112 of the RAM 54 in correspondence with the print position, and stores data of the current position that changes each time the carriage drive motor 31 or the type wheel drive motor 34 is driven in the RAM 54. The current position memory 114 and the type position memory 116 are stored.

Then, the CPU 46 processes the code data inputted from various function keys of the keyboard 3 with the control program read from the program memory 100 of the ROM 53, thereby transmitting control signals corresponding to the input code data to each of the drivers 39, 47 to 51. or display controller 5
Go to 2.

Furthermore, the CPU 46 uses character keys 4, 5, and 6 on the keyboard 3.
The code data input from the space key 7 or the code data of characters and symbols successively output from the print data memory 110 are processed by the control program read from the program memory 100 of the ROM 53. Thereby, a control signal corresponding to the code data is outputted to each driver 39, 47 to 51 of the printing mechanism driving means PM and the display controller 52, thereby controlling the printing mechanism and the display device.

That is, when controlling the printing mechanism driving means PM based on code data, a control signal is output from the CPU 46 to the type wheel drive motor driver 51, and a drive current is output from the type wheel drive motor driver 51 to the type wheel drive motor 34. Ru.

Then, the type wheel drive motor 34 rotates by a predetermined angle, and the type 3 of the type wheel 33 corresponding to the code data is rotated.
At the same time that G is set in the printing position in front of the printing hammer 37, a control signal is output from the CPU 46 to the ribbon lift motor driver 50, a drive current is output from the lift lift motor driver 50 to the ribbon lift motor 45, and the ribbon is lifted. The rotation of the motor 45 moves the holder 42 and the printing ribbon 40 to the third position via the drive shaft and cam mechanism.
It is driven to swing to the printing position shown in the figure.

Next, the CPU 46 sends the print hammer solenoid driver 3
When a control signal is output to the print hammer solenoid driver 39 , a drive current is output from the print hammer solenoid driver 39 to the print hammer solenoid 38 , the print hammer 37 hits the type 36 of the type wheel 33 , and characters and symbols are printed on the print paper 17 . It will be printed.

If there is no next key manpower within a predetermined time, C
A control signal is output from the PU 46 to the ribbon lift motor driver 50, the ribbon lift motor 45 rotates, and the holder 42 and print ribbon 40 are returned to the rest position. Furthermore, control signals are output from the CPU 46 to the carriage drive motor driver 48 and the ribbon feed motor driver 49, respectively.

On the other hand, a drive current is output from the carriage drive motor driver 48 to the carriage drive motor 31, the carriage drive motor 31 rotates by a predetermined amount, and the carriage 27 is moved in the printing direction by one character via the wire 32. On the other hand, a drive current is output from the ribbon feeding motor driver 49 to the ribbon feeding motor 43, and the ribbon feeding motor 43 rotates by a predetermined amount to feed the printing ribbon 40.

When the return key 9 is operated, the CPU 46 processes the code data from the keyboard 3 using the control program read from the program memory 100 of the ROM 53, thereby sending control signals to the carriage drive motor driver 48 and the platen drive motor driver 47. Output.

Then, a drive current is output from the carriage drive motor driver 48 to the carriage drive motor 31, and the carriage drive motor 31 rotates in the reverse direction to return the carriage 27 to the print starting position. At the same time, a drive current is output from the platen drive motor driver 47 to the platen drive motor 25, the platen drive motor 25 rotates by a predetermined amount, and the printing paper 17 is fed by one line.

Furthermore, when erasing characters by operating the correction key 23, the CPU 46 erases characters from the program memory 100 of the ROM 53.
When a control program for erasing characters is read in and a control signal is output to the ribbon lift motor driver 50, the ribbon lift motor 45 is rotated and the holder 42 is oscillatedly driven to the correction position shown in FIG. And CPU46 is RAM5
Based on the data in the current position memory 114 of No. 4, data in the print data memory 112 corresponding to the print position of the print head is read out, a control signal is output to the type wheel drive motor driver 51, and the type wheel drive motor 34 moves the type wheel 33. is rotated, the printed characters 36 that are the same as the characters or symbols to be erased are located in the printing position, and the printing hammer solenoid 38 is driven by the drive current from the printing hammer solenoid driver 39, and the printing hammer 37 is struck, and the printing paper 17 is rotated. The printed characters above will be erased.

In the above case, when the printed characters of the word currently being input are erased, the data corresponding to the erased printed characters are erased from the word data memory 110.

By the way, in the typewriter mode in which data input from the keyboard is sequentially printed, when a word separator key such as the space key 7 or turn key 9 is operated following an input word, the input data is first printed. A spell check is performed on the word that has been spelled, and when the spelling is correct, the operation corresponding to the delimiter data is executed, and when a spelling error is detected, the operation corresponding to the delimiter data is stopped. In order to make it easier to understand the explanation based on the flowchart, an outline of this separation operation stop control will be explained.

Code data corresponding to the character symbol keys 4, 5, and 6 inputted from the keyboard 3 are printed by the printing mechanism and written into the word data memory 110.

When word delimiter data corresponding to spaces, returns, tabs, periods, semicolons, commas, etc. stored in the delimiter data memory 104 of the ROM 53 is input, the delimiter data is stored in the delimiter data memory 118 of the RAM 54. written word data memory 110
The data, ie words, written in are spell-checked.

If the spelling of the word is correct as a result of the spell check, the operation corresponding to the delimited data will be executed and data input and printing will continue; however, if a spelling error is detected, an alarm buzzer will sound for a few seconds and the delimited data will be corrected. Corresponding operations such as spaces, returns, and tabs are aborted, or printing of semicolons, periods, commas, etc. is aborted.

At this time, the incorrectly printed characters are erased by operating the correction key 23, and the correct spelling is printed.

Then, the spelling of the words in the word data memory 110 that are written in the correct spelling is checked again, and when there are no errors, the operation corresponding to the delimiter data stored in the delimiter data memory 118 is executed, and the words are input and printed. continues.

When the name of a person or place is not stored in the dictionary memory 102 of the ROM 53, the delimiter data is executed by operating the same delimiter key twice in succession.

Next, the separation operation stop control performed by the control device C of the electronic typewriter will be explained based on the flowchart of FIG.

When the typewriter is powered on, this control starts and moves to step Sl (hereinafter simply referred to as 81, other steps are handled in the same way), where the separator operation stop flag memory 1 is set.
Initial settings such as setting flag F of No. 20 to 0 are performed, and the process moves to S2.

In S2, it is determined whether or not a key has been manually operated (whether or not the key has been operated), and if the key is not operated, 82 is repeated at minute intervals until the key is operated, and when the key is operated, the process goes to 83. In S3, ROM53
Based on the data in the delimiter data memory 104, it is determined whether the operated delimiter key is a space, return, period, semicolon, comma, etc., and if it is a delimiter key, the code corresponding to the delimiter key is stored in the RAM 5.
4 is written into the delimiter data memory 118, and the process moves to S4. If it is not a delimiter key, the process moves to Sll.

In S4, it is determined whether the flag F of the break operation stop flag memory 120 is 1 (cent), that is, whether the break operation has been stopped for the word currently stored in the word data memory 110, and the flag F is set to 1. When the flag F is 0 (reset), the process goes to 313, and when the flag F is 0 (reset), the process goes to S5.
Move to.

In S5, the data (words) written in the word data memory 110 are compared with the data in the dictionary memory 102 based on the spell check control program of the program memory 100, so-called spell check (conventional spell check function) is performed. ) is executed, and it is determined whether the spelling of the word is correct. If the spelling is correct, the process moves to S6, and if a spelling error is detected, the process moves to S8.

In S6, the operation corresponding to the delimiter data stored in the delimiter data memory 118 in S3 is executed.

In the above case, the CPU 46 outputs control signals to each driver of the printing mechanism.

In the next step 37, the flag F of the break operation flag memory 120 is set to O, and the process moves from S7 to 82. Then, steps 82 to S7 are repeated to check the spelling of the sequentially inputted words.

As a result of the spell check, if a spelling error is detected in the word, it is determined as NO in 85, and the steps from S5 to 88
Move to. The next steps 88 to S9 are steps for canceling the operation corresponding to the delimiter key, and in S8 a spelling error is detected, so an alarm buzzer (not shown) sounds for several seconds. In the next step 89, the operation corresponding to the delimited data stored in the delimited data memory 118 is stopped.

In the next step 310, the flag F of the break operation flag memory 120 is set to 1, and the process moves from SIO to 82.

Then, when the character symbol keys 4, 5, and 6 are operated for erasing characters and correcting the incorrect spelling, the result of determination in S3 is NO, and the process moves from S3 to Sll.

S8 to SIO are steps for character erasing and corrected printing, and in Sll, the delimiter operation stop flag memory 12 is used to perform a spell check again on the corrected word.
The flag F of 0 is set to O, and in the next step 312, when the correction key 23 is pressed, erroneously printed characters are erased,
When a character key is used, characters are printed for correction, or when a function key is used, the process corresponding to the function key is executed.
Transition from I2 to 82.

In the above case, when character printing for erasing or correcting a printed character is executed, the data of the erased character is erased from the word data memory 110, and the data of the corrected printed character is erased from the word data memory 110. written to.

Then, when the separator key is operated again, the spell check is executed again in S5 after going through steps 82 to S4, and if the spelling is correct, steps 85 to S7 are executed, the action corresponding to the operated separator key is executed, and the process goes to S2. Transition.

By the way, in the case of a unique word such as a person's name or place name that is not stored in the dictionary memory 102, S2 to S5 and S
After 8-SIO, the alarm buzzer sounds.

In this case, if the same delimiter key as the first delimiter key is operated again, the determination result in S4 is Ye.
s is determined, and the process moves from S4 to S13.

In S13, based on the data in the delimiter data memory 118, it is determined whether the operated delimiter keys are the same delimiter key or not. If the delimiter keys are not the same, the process moves to S14, where an alarm is displayed on the buzzer, alarm lamp, etc., and the process proceeds to S1.
4 to 82, and when the same separator key is selected, the process moves to S6, steps 36 to S7 are executed, the operation corresponding to the operated same separator key is executed, and the process moves to S2.

As explained above, when an error is detected in the spelling of a word as a result of spell checking, the operation corresponding to the word separator key is canceled, so especially when the separator key is return, the carriage 27 is moved and the printing paper 17 is moved.
Paper feeding is stopped, and words with spelling errors can be corrected easily and quickly, improving operability.

Furthermore, since the data corresponding to the word delimiter key is stored in the delimiter data memory 118, the delimiter key operated after correcting the word in which a spelling error has been detected is a different delimiter key that is not the same as the first delimiter key operated. Even when any one of the keys is operated, the delimiter operation may be performed corresponding to the stored delimiter data that was operated first.

Note that if a special key is provided separately and a unique person's name or place name that is not stored in the dictionary memory 102 is entered, the
It may be determined whether or not the second operated key is a dedicated key, and if it is a dedicated key, a dividing operation corresponding to the first operated dividing key may be performed.

In addition, the print position where the separator key is operated is stored as the relocate position, and after correcting a word with a spelling error using the backspace key 8, etc., the carriage 27 is moved to the relocate position using a separate key or locate key (path shown). The spelling check may be automatically performed when the spelling is correct, and if the spelling is correct, the delimiter action corresponding to the first delimiter key operated may be performed.

Although the above embodiment describes an electronic typewriter equipped with a decimal wheel, it goes without saying that the present invention can be similarly applied to a typewriter equipped with a thermal printer or a type ball type printer. The present invention is also applied to a CRT and a word processor equipped with a spell check function, and when a spelling error is detected as a result of spell check, the cursor stops moving to the next line when the separator key is set to return, and the separator key also stops moving to the next line. When tabbing, the cursor may be stopped from moving to the next tab position.

It should be noted that the above-mentioned embodiment is merely an example, and those skilled in the art can make various modifications without departing from the spirit of the present invention.
