Description

TECHNICAL FIELD The present invention relates to a data processing system that prints out character data corresponding to input data, and particularly has a printing function suitable for use in a typewriter with memory, a word processor, and the like. Data processing system.

2. Description of the Related Art The conventional printing methods of this type of data processing system are roughly classified into the following two methods. The first method is necessary items for printing character data input in advance, for example, paper size, character spacing, line spacing, vertical / horizontal writing designation,
After setting items such as pagination designation, left and right margins, upper / lower margins, the number of print copies, and print range to target values, print output is performed in a predetermined format.

In the second method, when a key for activating a printing operation is operated, the character data input before the key is operated is printed out from the current position of the printer head.

In the first method, since all the character data have to be input and then the data regarding many items necessary for specifying the print output must be input, the operation is complicated, and the print output format is prepared in advance. Since it is selected from the inside, there is a drawback that it is not possible to print out in a free format. In the second method, a predetermined length, for example, 1
It is configured to print out each time character data for a line is input, and moreover, a predetermined key input is required when performing the printout. Therefore, the operation is complicated, and the range of the input character data to be printed out this time is not displayed. Therefore, the operator has no choice but to rely on the memory, and an operation error is likely to occur.

Further, as shown in FIG. 6, assuming that the position of the printer head PH currently placed on the paper (B) is P1, the print output is started from the position P1. Therefore, the input character string data shown in one line on the display screen (a) is
As shown in FIG. 7B, the print result is printed over a plurality of lines. Therefore, there is a problem that the occurrence rate of erroneous operations due to this is very high.

The function of each circuit unit of the processing circuit 100 described above is advantageously realized by a microcomputer, and the processing content thereof will be described based on the flowcharts shown in FIGS. 2 to 5.
In FIG. 2, the program is started and step 500 is executed.
When a key is input from the operation unit 10 with, the next step 50
In 2, it is determined whether or not the operated key is a character input key. When it is determined to be “Yes” in step 502, the process proceeds to step 504, and in step 504, what mode is currently set is determined. Then step 50
In step 6, it is determined whether or not the mode determined in step 504 is the character input mode, and in the buffer in which the mode is the character input mode, it is further determined in step 508 whether or not the reading input mode. If it is determined in step 508 that the reading input mode is not set, the process proceeds to step 514. If it is determined in step 508 that the input mode is the reading input mode, the process proceeds to step 510. In step 510, it is determined whether the candidate character string selected based on the reading information is being selected, and the operator displays it. If the candidate character string displayed on the screen of the device 20 is being selected, the process proceeds to step 512.
The determination as to whether the candidate character is being selected in step 510 is made as follows. That is, a control signal for requesting the next candidate is output from the next process discriminating circuit 110 in FIG. 1 to the candidate holding circuit 119, and this control signal is used as a candidate confirmation process (step 512, step 546).
Since it is always in the "selected state" during step S4, it is possible to determine in step 510 whether the candidate character is being selected by checking whether this control signal is "selected". it can. In step 512, a specific candidate character string of the plurality of candidate character strings is determined. That is, when a candidate character string is displayed on the screen of the display device 20 and a key unrelated to candidate selection such as the next candidate key is operated, the candidate character string is fixed.

Next, in step 514, the confirmed character string information is taken in as text and edited, and in step 516, text display data is created based on the edited text data, and then in step 518, the display device 20 is displayed. The content is displayed on the screen.

Further, in step 520, it is determined whether the print mode is the typewriter mode. Here, in the present embodiment, three printing modes, a normal printing mode, a sequential printing mode, and a typewriter mode, can be designated by the operation unit 10.

The normal print mode is a mode in which when the print key of the operation unit 10, which is a key for requesting the start of printing, is operated, printing is performed in page units or document units at once from the beginning of a page or document to the end of a page or document. Is. What is the sequential print mode?
When you operate the line feed or page break keys on the operation unit 10,
In this mode, the current range from the beginning to the end of the line is printed from the current print head position.

Further, the typewriter mode is a mode in which the conversion candidate for “reading” is fixed and at the same time, the fixed character string is printed from the current head position.

If it is determined in step 520 that the typewriter mode is in effect, the process proceeds to step 574 in FIG. If it is determined in step 520 that the mode is not the typewriter mode, the execution of the program ends. If it is determined in step 510 that the candidate character string is not selected, the process proceeds to step 522, in which the reading information input from the operation unit 10 is stored in a predetermined storage area, and in step 524. Reading display data is created from this reading information, "reading" is displayed on the screen of the display device 20 in step 526, and the execution of this program ends.

On the other hand, when it is determined that the key of the operation unit 10 operated in step 502 is not the character input key, the process proceeds to step 528, and in step 528, the operated key has the same “reading”.
It is determined whether or not it is in the next candidate mode of the operation unit 10 for reading the next candidate character string for and displaying it on the screen of the display device 20. If the key operated in step 528 is determined to be the next candidate key, the next step
At 530, the next candidate character string for the same "reading" is selected, and at step 532, the next candidate character string data is stored in a predetermined storage area.

Further, in step 534, character string display data to be the next candidate is created, in step 536, the next candidate character string is displayed on the screen of the display device 20, and the execution of this program ends. Here, the processing contents of steps 500 to 536 will be specifically described with reference to FIG. In step 500, the operator "Kanjiha"
Character is input, it is determined in step 502 that the character is input, and the process proceeds to step 504, and the current mode is determined. Then, in step 506, the character input mode is determined, and in step 508, the reading input mode is determined. Here, since the key input character is simply displayed on the display device 20, the reading input mode is determined. Since no kanji candidates have been selected yet, it is determined to be “NO” in step 510 and step 522.
In step 524, reading information is stored and reading display data is created and display 526 is executed. At this time, the character string "Kanjiha" is displayed on the display screen (a) of the display device 20 as an unconfirmed display 600 such as a reverse character as shown in FIG. 7 (A). Here, the process of step 522 corresponds to the operation in which the read data is sent from the character input circuit 102 to the read information storage area 104, and the process of step 524 is the read display circuit 106.
Then, the display data is sent to the display device 20.

When the next candidate key of the operation unit 10 for kana-kanji conversion is first operated in this state, the first candidate character string "Kanji wa" is displayed on the display screen (as shown in FIG. 7B). I)
Is displayed in. That is, when the next candidate key is first operated, a next candidate request signal is sent from the next process discriminating circuit 110 in FIG. 1 to the candidate display circuit 119. The character data input from the operation unit 10 is input from the next process determination circuit 110 to the character input circuit 1
02, sent to the candidate selection circuit 116 via the reading information storage area 104. Here, the candidate selection circuit 116 searches the dictionary file 118 to select the character string of the first candidate, and using this as candidate information, the candidate character string storage area 120 and the candidate display circuit 119.
Send to. This processing corresponds to the processing of steps 530 and 532. Since the candidate display circuit 119 has been selected by the next candidate request signal, the character string "Kanji" is immediately displayed on the display screen (a) of the display device 20 as shown in FIG. Displayed in unconfirmed display 600. The processing up to this point corresponds to the processing from step 534 to step 536 in FIG.

When the next candidate key is operated while the character string of the first candidate is displayed, it is determined in step 502 that it is not the character input key, and the process proceeds to step 528. Proceed to 530. After that, the operation is the same as the display of the character string of the first candidate, and thus the description thereof will be omitted. By the processing so far, FIG. 7C is displayed on the display screen (a) of the display device 20.
As shown in, the character string of "secretary is" is displayed on the unconfirmed display 600 such as a reverse character. In this state, for example, the display device 2
As shown in Fig. 7 (D), the display screen of (0) of "0" is "I".
Is input, it is determined in step 502 that the character is input, and the process proceeds to step 504, step 506, and step 508. Because the reading input mode is selected for inputting characters,
Further, it proceeds to step 510. In step 510, the character string candidate of "secretary is" has not been confirmed yet, so "YES" is determined and the process proceeds to step 512. The candidate determination process in step 512 is the first
The candidate information is sent from the candidate selection circuit 116 in the figure to the candidate character string storage area 120, the candidate information is sent to the candidate confirmation circuit 108, and the character string "secretary is" is reversed as shown in FIG. 7 (C). In order to bring the candidate display circuit 119 displayed in the unconfirmed display 600 such as “into the non-selected state”, the next candidate request signal output from the next process determination circuit 110 is turned off. The confirmed character string is displayed in step 518 through the processing in steps 514 and 516. Here, the processing of step 514 corresponds to the operation of the text editing circuit 112,
The process of step 516 corresponds to the operation of the text display circuit 114.

In FIG. 2, if it is determined that the key operated in step 528 is not the next candidate key, the step in FIG.
Move to 538. In step 538, it is determined whether the operated key is a line feed or page break key.
If it is determined to be “Yes” in 538, the process proceeds to step 540, and in step 540, it is determined what the currently set mode is. Further, when it is determined in step 542 that the print mode is the sequential print mode, the process proceeds to step 574 in FIG. On the other hand, when it is determined in step 542 that the print mode is not the sequential print mode, the process proceeds to step 544, and in step 544, it is determined whether the candidate character string selected based on the input reading information is being selected. If it is determined that the candidate character string is not being selected in step 544, the process proceeds to step 548. If it is determined in step 544 that the candidate character string is being selected, a specific candidate character string of the plurality of candidate character strings is determined in step 546. Note that here, the step
Steps 544 and 546 are the same as steps 510 and 512 in FIG. 2, but steps 510 and 516 in FIG.
In contrast to the processing for confirming the candidate when the character string is input in, the steps 544 and 546 in FIG. 3 are the processing for determining the candidate when the line feed or page feed key is operated in step 538. Then, in step 548, the confirmed character string is taken in as text, edited, and further, text display data is created based on the text data edited in step 550, and then in step 552 on the screen of the display device 20. The contents are displayed, and the process proceeds to step 554. In step 554, it is determined whether or not the currently designated print mode is the typewriter mode, and when it is determined in step 554 that the current print mode is the typewriter mode, the steps shown in FIG. Continue to 574. If it is determined in step 554 that the current print mode is not the typewriter mode, then the execution of this program ends.

When it is determined that the key operated in step 538 is not the line feed or page feed key, the process proceeds to step 556, and step 5
At 56, it is determined whether the further operated key is the print key. If it is determined in step 556 that the operated key is the print key, the process proceeds to step 574 in FIG. 5, and if it is determined in step 556 that the operated key is not the print key, the step is further performed. It is determined whether the key operated at 558 is the print mode setting key. If “Yes” is determined in step 558, a specific print mode of the three print modes is set in step 560, and execution of this program ends.
If it is determined to be “NO” in step 558, it is further determined in step 562 whether the operated key is the print format key requesting the setting of the print format, and in step 562, “NO”. If it is determined to be "," other processing is performed and the execution of this program ends. If it is determined as “Yes” in step 562, step
Use 564 to set the character spacing, line spacing, paper size, left and right margins, vertical writing / horizontal writing, etc., and determine the print format. FIG. 8 shows the state when the print format is set. In FIG. 8, in the case of a device configuration with a limited display screen such as a small device such as a typewriter with an electronic memory,
Although the method of sequentially changing the display was shown, in the case of a device configuration that uses a conventional CRT display or the like that can display multiple lines, display data is displayed for multiple items at a time and each item is displayed on the display screen. It may be configured to set the item.

Further, when the print mode key of the operation unit 10 for setting the print mode is operated, the display shown on the display screen (a) is displayed as shown in FIG. 9, and one of the three print modes is selected. can do.

As described above, in the present embodiment, it is possible to select three types of print modes, that is, the normal print mode, the sequential print mode, and the typewriter mode. However, the print format described above is also effective in any print mode. Therefore, if preset, it is not necessary to reset again at the start of printing in any print mode.

When it is determined in step 506 in FIG. 2 that the mode is not the character input mode, the process proceeds to step 566 in FIG. 4, in step 566 it is determined what mode is currently set, and the process proceeds to step 568. In step 568, it is determined whether or not data for designating the print format is being input. If it is determined that the print format is not being input, other processing is performed, and the execution of this program ends.

On the other hand, if it is determined in step 568 that the print format is being input, the corresponding item is fetched in step 570, then the print format data is set in step 572, and the execution of this program ends.

Also, step 520 in FIG. 2 and step 54 in FIG.
2. If "Yes" is determined in step 566 and step 554, the process proceeds to step 574 shown in FIG. 5, and in step 574 it is determined what mode is currently set. Further, in step 576, it is determined whether or not the currently designated print mode is the normal print mode, and if "NO" is determined in step 576, the process proceeds to step 580. If "Yes" is determined in step 576, the position of the printer head is initialized.
That is, the printer head is moved to the left end of the effective print range. Next, in step 580, the range to be printed out of the text data is calculated based on the print mode information and the edited text data, the print format is created in the next step 582, and the print range determined in step 580 is further created. The relevant portion is extracted from the text data based on the information to create print data. Further step 58
In step 6, this print data (print data) is output to the printing device 30, and then in step 588 it is determined whether the print mode currently specified is the typewriter mode. If "Yes" is determined in step 588, execution of the printer is ended as it is.

On the other hand, if it is determined to be “NO” in step 588, the printer head is moved to the left end as in step 578,
Next, in step 592, one line of paper is fed, and the execution of this program ends.

Here, in the typewriter mode, the printer head is not initialized and the paper feed for one line is not performed after printing is completed because the next candidate character string to be determined follows the previous printed character string. This is because it needs to be printed. This state will be described with reference to FIG. That is, FIG.
If the printer head is located at position P2 with respect to the paper (b) when the candidate character string “secretary is” is displayed on the display screen (b) as shown in, the hiragana “i” will be displayed at this time. When the indicated key is operated, the character string “Secretary is” is confirmed as shown in FIG. 8B, the character of the confirmed character string “Secretary is” is printed from position P2, and the printer head PH indicates “ Stop at the next position of "ha".

In the typewriter mode in the present embodiment, when a character that can be a prompting confirmation but cannot be a conversion target is input, such as an alphabetic character, a space character, or a line feed, the character is input. At the same time, the character is printed. That is, when the space key is operated, one space character is immediately printed. (Actually, the head moves right by one character.) When the line feed key is pressed, the line feed is printed out (paper feed for one line). As a result, in the typewriter mode, the head can be moved to any position on the paper by space input and line feed input, and printing can be started from that position (position designation character). is there.

A backward key (backspace) and a reverse line feed (backline feed) key may be provided on the operation unit 10 to move the head of the printer vertically and horizontally in the typewriter mode.

In the conventional data processing system, the screen image and the image after the actual printing are not necessarily associated with each other. Further, although some key input operation is always required for the printing operation after the character data is input, the printing method by the typewriter mode in this embodiment realizes a one-to-one correspondence between the character data input and the print output. Therefore, erroneous operation due to the difference between the screen image of the display device and the print result is prevented, and unnecessary key operation by starting the print operation when the conversion candidate character string is determined becomes unnecessary, and the final output of the document or data is the print output. The operability regarding can be dramatically improved.

Effects As described above, according to the present invention, a one-to-one correspondence between character data input and print output is realized, and thus operability for print output can be improved.
