Abstract

PURPOSE:To shorten the retrieving processing time of previously set specific retrieving processing control out of plural retrieving processing control by providing the document processor with a means for inhibiting I/O processing control to be executed by interrupting processing during the execution of the specific retrieving processing control. CONSTITUTION:While executing various retrieving processing control for retrieving stored information storing means or an input information storing means based upon various inputs from an input means, a control means controls the input means and an output means by interrupting processing based upon an input from the input means or a retrieved result. On the other hand, an interrupting processing inhibiting means completely inhibits I/O processing control to be executed by interrupting processing when the previously set specific retrieving processing control out of plural retrieving processing control is executed. Since the I/O processing control to be executed by interrupting processing is inhibited during the execution of the specific retrieving processing control, the retrieving processing time of the specific retrieving processing control can be shortened and the working efficiency of document processing can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device, and particularly to one that is designed to shorten the search processing time of a specific search processing control set in advance.

[Prior art]

In general, word processors and electronic typewriters for Roman languages are equipped with a keyboard, liquid crystal display, printing mechanism, etc., as well as a fixed dictionary memory that stores spelling data for many words, and some are equipped with various search functions. It has been put into practical use.

These search functions include, for example, a spell check function that checks the spelling of words input manually from the keyboard against spelling data stored in the fixed dictionary memory or user dictionary memory, and a spell check function that checks the spelling of words entered manually from the keyboard and the spelling data stored in the fixed dictionary memory or user dictionary memory. Candidate word search function to search for candidate words, search/replace function to replace specified words in document data with other words, words "tO", "too"
, rtwo", when words with similar pronunciations that are easily confused are detected in the document data, a word alert function that warns you and displays the similar words, and a word alert function that responds to "(" and [[]) in the document. A punctuation union function has been implemented that warns when general rules for document creation are violated, such as adding ")" or "]" or capitalizing the first letter of each sentence. has been done.

By the way, while executing the various search processes, the CPU of the control device periodically interrupts various input/output processes to control peripheral devices (input/output devices) such as keyboards, displays, and printing mechanisms. The CPU is equipped with a plurality of internal timers, and is also equipped with a dedicated transmitting element for commanding an external interrupt from the outside to the cPU.The interrupt signal from the internal timer is used to control the stepping motor for driving the carriage of the printing mechanism and the daisy chain. Stamping motors for driving wheels, etc. are controlled by internal interrupt processing approximately every predetermined minute time, and keyboard key scanning and display control of display information are controlled at precisely every predetermined minute time using interrupt command signals from external transmitting elements. Each of these is controlled by external interrupt processing.

In this case, if an interrupt process occurs during execution of the search process, the search process will be interrupted.

[Problem to be solved by the invention]

In conventional word processors and electronic typewriters for Roman languages, interrupt processing is repeatedly executed at minute intervals during search processing, so it is especially difficult to perform interrupt processing during candidate word search processing, which tends to take a long time. However, there are problems in that the number of interrupt processing increases, the search processing time becomes significantly longer by the time required for the interrupt processing, and the efficiency of document processing decreases as a result.

The printing mechanism PM includes at least a platen 4 that feeds printing paper, a stepping motor that drives it, a carriage 5 that is supported by a guide parallel to the platen 4, a stepping motor that drives it back and forth in the left and right direction, and a wheel cassette. A type wheel 6 housed in the type wheel 6 and a stepping motor that drives it, a print ribbon 8 housed in a ribbon cassette 7 and a stepping motor that winds it, a solenoid 9 that hits the type on the type type wheel 6, etc. are provided. The stepping motor and solenoid 9 are each driven by a drive signal from a drive circuit 14.

Next, the control system of the electronic typewriter 1 is constructed as shown in the block diagram of FIG.

The display mechanism DM includes a liquid crystal display 10 and a display RAM for outputting display data to the display 10.
and a display controller 11 including a character generator ROM storing a large number of dot patterns such as characters and symbols. Incidentally, reference numeral AM designates an alarm mechanism that includes a buzzer 12 and a drive circuit 13 that causes the buzzer 12 to sound.

The control device C includes a CPU 17, an input/output interface 15 connected to the CPU 17 via a bus 16 such as a data bus, a ROM 1B/19, and a RAM 20.

Here, the CPU 17 is provided with a necessary number of internal timers for controlling each stepping motor of the printing mechanism PM by interrupt processing. Furthermore, although not shown, the control device C is provided with a necessary number of dedicated transmitting elements for inputting interval interrupt signals that command interval interrupts that control key scanning and display control of the keyboard 3 through interval interrupt processing. .

The program memory of the ROM 1B includes a control program that controls the display mechanism DM and the printing mechanism PM in response to code data input from the keyboard 3, and a control program that stores the code data in the input data buffer 21 and the manual word memory 24. , a cursor movement control program that moves the cursor in response to the operation of a cursor movement key, an initial setting processing control program that initializes the printing mechanism PM, etc. immediately after power is turned on, a spell check/candidate word search control program, A search/replace control program that replaces a specified word with another word, a word alert control program that warns about words that have similar pronunciations and are easily confused, and a punctuation program that alerts you when general rules for document creation are violated. A union control program, an interrupt processing control program for various interval interrupt processing such as display control when an interval interrupt signal is input, and the like are stored.

The spell check/candidate word search control program stores a spell check processing subroutine for executing spell check processing on input words and a candidate word search processing subroutine for searching the dictionary memory 19 for candidate words for misspelled words. ing.

In the dictionary memory of the ROM 19, spelling data regarding approximately 70,000 words, for example, is stored in alphabetical order like a normal dictionary in order to check the spelling of words.

Here, the spell check process is a well-known and common process, so it will be briefly explained. The word data of the word input from the keyboard 3 and stored in the input word memory 24 is compared with a large number of word data stored in the dictionary memory of the ROM 19. It is used to check spelling by comparison.

Candidate word search processing is a well-known and general process, so to briefly explain it, it is a process of repeatedly searching the dictionary memory 19 to see if there is a word in which each letter of the misspelled word is replaced with each letter of the alphabet, or a similar process. This method searches for correctly spelled candidate words related to the misspelled word by transposing character strings based on rules that make misspellings easier.

A simple explanation of word alert processing is that the word "
When words that have similar pronunciations and are easy to act on, such as "to", "rtoo", and "rtwoJ", are detected in the document data, a warning is given and the similar words are displayed.

A brief explanation of puncture union processing is as follows.
In the document data, ")" or F that corresponds to "(" or "[")
] It warns when general rules for document creation are violated, such as when j does not exist, when the first letter of each sentence is not capitalized, etc.

The input data buffer 21 of the RAM 20 has a memory capacity for approximately 5 print lines, and document data consisting of a plurality of words input from the keyboard 3 is stored therein.

The line buffer 22 receives input from the keyboard 3 or reads out from the text memory 23 and displays the display 1.
Data such as characters displayed in 0 is stored.

The text memory 23 stores input document data. The input word memory 24 stores the latest input word data.

The candidate word memory 25 stores data on correctly spelled candidate words searched for misspelled words.

The RAM 20 is further provided with various memories, counters, etc. for temporarily storing the results of calculations performed by the CPU 7.

The interrupt command memory 26 stores interrupt command codes for executing various interrupt processes.

The flag memory 27 has a spell check mode that is set (data is "1") when the spell check mode is set by operating the spell check mode setting key and reset (data is "0") when it is canceled. Flag data of flag F is stored.

Next, the control device C of the electronic typewriter 1 performs the following steps.
The initial setting processing control routine is based on the flowchart in Figure 4, the spell check/candidate word search control routine is based on the flowchart in Figure 5, and the interrupt processing control routine is based on the flowchart in Figure 6. explain. In addition, St (i=1.2
．． 3...) are each step.

First, to explain the initial setting processing control, this control is started when the typewriter 1 is powered on, and first, each output port of the input/output interface 15 and the display mechanism D
Initial settings for hardware such as the display controller 11 and RAM 20 of M are executed (SL), initial settings for starting the main program and interrupt handling are executed (S2), and initial setting control for the printing mechanism PM is performed by internal interrupts. To execute, set the interrupt time (for example, about 1m5ec) to the internal timer (S3)
. At this time, this internal timer starts counting.

Next, in order to execute initial setting control of the printing mechanism PM by interrupt processing, an initial setting command code is stored in the interrupt command memory 26 (S4), and an interrupt enable command E is stored.
Interrupt acceptance is enabled by setting the internal interrupt enable flip-flop (S
5), initial setting control of the printing mechanism PM is executed (S6
). When the initial setting process of the printing mechanism PM is completed (S7: Yes), various internal interrupts and interval interrupts can be accepted from then on.

Here, for example, internal interrupt processing control in which the stepping motor of the printing mechanism PM is controlled by one drive pulse every predetermined time will be described.

When this interrupt processing is started, the register of the CPU 17 is saved to the stack (S41), and the remaining count value of the drive pulses supplied to the stepping motor becomes "0".
In other words, when processing a new interrupt (S42:N
o) The command code stored in the interrupt command memory 26 is searched, and when the command code is stored (
S43: Yes s) Processing according to the command code, that is, the stepping motor for driving the carriage and the stepping motor for driving the platen are driven by one drive pulse (S
44). However, in S43, the interrupt command memory 26
When the command code is retrieved by the interrupt handling routine, that command code is erased.

Next, if the remaining count value is not "0" and the driving process is not completed (S45: No), the time for executing the next interrupt process is set in the internal timer (
846), returns the contents of the register that had been saved to the stack to the register, ends the interrupt processing (S47), and
The main routine processing interrupted by the TI instruction continues. Then, each time the time set in S46 elapses, interrupt processing is performed, that is, S41 to S42: Yes, S44,
S45: No, S46 to S47 are executed.

On the other hand, when the drive process ends while executing 344 (
(S45: Yes), then a time for searching the command code is set in the internal timer (84B), and the main routine processing interrupted by the RTI command is continued through S47.

By the way, when a character key is operated (S8: Ye
s, S9・SIO: No), the character code corresponding to the character key is stored in the input data buffer 21 and input word memory 24. Then, word separator keys such as the space key and return key are operated (S8/S9: Ye
s), when flag F is set (Sll:Ye
s), or when the candidate word display key is operated (
S8/SIO: Yes), spell check/candidate word search processing control is executed (S12).

When this process control is started, the input word data stored in the input word memory 24 is read out (S21),
The spelling data stored in the dictionary memory 19 is searched for the input word data (S22), and if the same word as the input word does not exist and there is a misspelling (323: Ye
s), the buzzer 12 sounds to warn you of the misspelling (
S24), when a series of interrupt processing is being executed based on the remaining count value of the drive pulses supplied to each of the stepping motors of the printing mechanism PM (S25: Yes), the interrupt processing is stopped until the count value reaches "0". S25 is repeated until the series of interrupt processing is completed.

When the count value becomes "0" and the interrupt processing is completed (S25: No), the internal interrupt enable flip-flop is reset by the interrupt enable instruction DI, thereby disabling the reception of interrupts (S2
6). That is, from this point on until interrupts are permitted in S30 or 332, the above-described internal interrupt processing and interval interrupt processing are completely prohibited.

Next, the dictionary memory 19 is searched for a candidate word related to the misspelled word stored in the input word memory 24 (S27), and when a candidate word is detected (328:
Yes), all candidate words are stored in the candidate word memory 25 (S29).

Then, acceptance of an interrupt is permitted by the interrupt enable command El (S30), all candidate words stored in the candidate word memory 25 are displayed on the display 10 (S31), and the process returns to the main routine. On the other hand, if the spelling of the input word is correct (S23: No), the process immediately returns to the main routine, and if no candidate word is detected (328: No), the interrupt is accepted by the interrupt enable command El as in S30. After being permitted (332) and warning with buzzer 12 (S33)
, return to the main routine.

Furthermore, when keys such as the search key, replace key, sword alert key, puncture union key, etc. are operated (S8: Yes, S9/SIO: No)
, a search/replace process, a word alert process, and a puncture union process corresponding to the operated function key are executed (S13).

As explained above, since any interrupt processing control is prohibited while candidate word search processing control is being executed, the search processing time required for candidate word search processing control does not include the extra processing time spent on interrupt processing control. The original search processing time can be significantly reduced.

Note that interrupt processing may be prohibited while spell check processing control, word alert processing control, punctuation union processing control, etc. are being executed, and various search processing controls are possible with fixed dictionary memory and user dictionary memory. Of course, the present invention can be applied to document processing devices such as word processors for Roman languages and word processors for Japanese.
