Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a data processing device, and particularly relates to input data (such as words) and associated data (such as correct spelling, synonyms, parts of speech, conjugations, etc.). The present invention relates to a data processing device capable of retrieving various types of data from a related data memory and displaying the retrieved data on a display.

(Prior Art) A conventional data processing device, such as an electronic typewriter having a spell check function, displays input words on a display while creating a document, and also checks the spelling of the input words. In this type of data processing device, if a misspelling is found during a spell check, a buzzer sounds at that point. Furthermore, a correctly spelled word is displayed on the display at a position away from the word to be spell checked.

(Problems to be Solved by the Invention) In the conventional data processing device described above, correctly spelled words are displayed at a position away from the spell checked word. Therefore, each time the user checks the displayed correctly spelled word, the user must take his or her eyes off the document creation position and move to another location where the correctly spelled word is displayed.

Therefore, there is a problem in that work efficiency during document creation is extremely poor.

Furthermore, it is necessary to reserve a dedicated area on the display to display the searched word with the correct spelling, which causes the problem that the display cannot be used effectively.

(Object of the Invention) An object of the present invention is to improve work efficiency during data input by making it possible to display related data on a display in a position close to input data, and to display related data. The purpose is to make effective use of the display by eliminating the need for a dedicated area.

(Means for Solving the Problems) As shown in the functional block diagram of FIG. 1, the data processing device according to the present invention includes an input means for inputting character and symbol data, and input data from the input means. a display means for displaying on a display; a related data memory storing related data related to the input data; and a search means for searching the related data memory for data related to the input data; The apparatus further includes display control means for reducing the display of the corresponding input data on the display and displaying the corresponding related data in the empty area created by the reduction of the display when related data is retrieved.

(Operation) Input data input from the input means is displayed on the display by the display means. The search means searches for data related to the input data from the related data memory. When the related data is retrieved, the display control means reduces the display of the input data on the display and displays the corresponding related data in the empty area created by the reduction of the display.

(Effects of the Invention) According to the data processing device according to the present invention, since the display control means as described above is provided, when the related data corresponding to the input data is retrieved from the related data memory and displayed on the display, the input It becomes possible to display related data in correspondence with positions close to the data. As a result, it is no longer necessary to take one's eyes off the display position of the input data to check the displayed related data, and work efficiency during data input can be improved. Furthermore, since a dedicated area for displaying related data is no longer required, the display can be used more effectively.

Furthermore, for spell checking and spelling correction of input words,
Spell checking, search for candidate words, and display control of input words and candidate words are performed as described below.

Next, a control flowchart of the data processing apparatus according to the present invention will be explained based on FIGS. 4(a) to 4(C). still,
In this embodiment, a memory mode case will be described for convenience.

In FIG. 4(a), this control is started when the typewriter is powered on. First, in step Sl (hereinafter simply referred to as Sl, and other steps are handled in the same way), the control program stored in the program memory 81 is read to the main CPU 76, and initial settings such as resetting the misspelling flag 95, which will be described later, are performed. After is executed, the process moves to S2. In S2, we wait for key personnel,
If we have the key human resources, we will move on to S3. In S3, it is determined whether the misspelling flag 95 is set. At the initial stage, the misspelling flag 95 is reset, so the process moves to S4.

In S4, it is determined whether the input key is the character/symbol keys 10-12 or the space key 13. Character symbol key 10-1
If it is not 2 or space key 13, the process moves to S5. S
In step 5, it is determined whether the input key is the return key 15 or not. If it is not the return key 15, the process moves to S6. At S6, processing is performed to perform operations as a general typewriter based on commands from input keys.

Input key is character symbol key 10-12 or space key 1
3, the control moves from S4 to 38 in FIG. 4(b). In S8, the input data corresponding to the latest two lines are sequentially stored in the line buffer 93, and the input data regarding the latest word is also stored in the input word memory 94.

Next, the process moves to step 39, and the data in the line buffer 93 is transferred to the display device. The display device reads a display pattern corresponding to the data from the character generator 74 and outputs it to the display controller 73. Display controller 73 outputs a display signal to LCD display 71 according to the display pattern data. The display dot pattern in this case is a normal font consisting of a dot matrix of 5×1 characters, and a specific example thereof is shown in FIG. 5(a). Next, the process moves to step 310, where it is determined whether the input key is a delimiter key (keys such as space, comma, bill, etc.). Oysters inside
If is not a delimiter key, the process returns to S2. That is, until the delimiter key is input, the input data is simply stored and displayed in S8 and S9.

In SIO, if the input key is a delimiter key, Sll
to move to. 31), the word stored in the input word memory (the latest input word) is stored in the dictionary memory 82.
A spell check is performed by searching for words with the same spelling within the search terms, and if there is a misspelling, a search for candidate words is performed by searching for words with one letter difference.

If candidate words are detected, all detected candidate words are stored in candidate word memory 96. next,
Proceeding to S12, it is determined whether or not there is a misspelling in the spell-checked word. If there is no misspelling, the process returns to 32 in FIG. 4(a). If there is a misspelling in 312, the process moves to S13.

In S13, a misspelling flag 95 is set. This set means to proceed to the process of replacing the input word with the detected candidate word. Next, the process moves to S14, and the first candidate word among the candidate words stored in the candidate word memory 96 is stored in the candidate word buffer 97. In S15, the code data of the latest input word targeted for spell checking is converted into a reduced font (5 characters per character).
The data is converted into code data of a font consisting of a x5 dot matrix), and the data is transferred to a display device. The display device reads a display pattern corresponding to the data from the character generator 74 and outputs it to the display controller 73. Display controller 73 outputs a display signal to LCD display 71 according to the display pattern data. As a result, the latest input word displayed in a normal font (a font consisting of a dot matrix of 5×1 characters) is converted to a reduced font and displayed in the upper half of the same position. Next, the process moves to step 316, where the code data of the candidate word in the candidate word buffer 97 is converted into code data of a reduced font, and the data is transferred to the display device. The display device reads a display pattern corresponding to the data from the character generator 74 and outputs it to the display controller 73. The display controller 73 is
A display signal corresponding to the display pattern data is output to the LCD display 71. As a result, the candidate word is displayed in a reduced font in the lower half of the same position as the latest input word, which is displayed in a reduced font. For example, in Figure 5(a), if ``rEXANPLE'' is determined to be a misspelling and the candidate word is ``rEXAMPLE'', then rEXANPLEJ and rEXAMPLE are each represented in reduced fonts as shown in Figure 5(b). At the same time, rEXANPLE, + and rEXAMPLEJ are displayed in two rows, upper and lower. As a result, there is no need to take one's eyes off the display position of the input word to check the displayed candidate words, and work efficiency during text input can be improved. Furthermore, since a dedicated area for displaying candidate words is no longer required, it becomes possible to effectively utilize the LCD display 7. When the process in S16 is completed, the process returns to 32 in FIG. 4(a).

Here, the operator determines whether to replace the latest input word with the displayed candidate word. If you want to replace it with another candidate word, press the next candidate key 16. At this stage, the misspelling flag 95 has already been set, so the control moves from S3 to 317 in FIG. 4(C).

In S17, it is determined whether the input key is the next candidate key 16 or not. Since the next candidate key 16 has been input, the determination is Yes, and the process moves to S18. At 51B, after searching the candidate word memory 96 for the next candidate word, the process moves to S19.

In 319, it is determined whether the next candidate word exists. If the next candidate word does not exist, the process moves to S20, and after displaying that there is no next candidate word, 32 in FIG. 4(a)
Return to If the next candidate word exists in S19, the process moves to 321, the next candidate word is stored in the candidate word buffer 97, and then the process moves to 316 in FIG. 4(b). At 316, as described above, the next candidate word is rendered in reduced font and displayed at the same position in place of the previous candidate word displayed in reduced font. This allows the operator to check the next candidate word without taking his eyes off the display position of the input word. When the process in S16 is completed, the process returns to 82 in FIG. 4(a).

If the operator determines that the latest input word should be replaced with the displayed candidate word, he or she presses the spell conversion key 17. Since the misspelling flag 95 has already been set, the control goes from S3 to S via 817 in FIG. 4(C).
22. In S22, it is determined whether the input key is the spell conversion key 17 or not. Since the spell conversion key 17 has been input, the determination is Yes, and the process moves to S23. S2
3, the latest input word data in the line buffer 93 is replaced with the candidate word data in the candidate word buffer 97. Next, in S24, shrinkage is performed.

Converts candidate words displayed in small font to normal font and displays them at the same position on the display. Next, the process moves to 325, and after resetting the misspelling flag 95, the process returns to 32 in FIG. 4(a).

If the operator determines that he wishes to leave the displayed latest input word as it is without rewriting it, he does not press the spell conversion key 17 but presses the return key 15. Since the misspelling flag 95 is set, the control moves from S3 to 326 via S17 and S22 in FIG. 4(C). In S26, it is determined whether the input key is the return key 15 or not.

Since the return key 15 was pressed manually, the determination is Yes, and the process moves to S27. In S27, the latest input word being displayed in a reduced font is converted to a normal font and displayed at the same position on the display.

Further, the contents of the line buffer 93 are left unchanged. Next, the process moves to S25, and after resetting the misspelling flag 95, the process returns to 32 in FIG. 4(a). In addition, the input keys are return key 15, next candidate key 16, and spell conversion key 1.
If it is other than 7, the control is S3, S17, S22, S2
After passing through 6 and moving to 328, after sounding the buzzer, the 4th
Returning to 82 in Figure (a).

If words are input one after the other, the spell check control will be performed each time the separator key is input. Once a series of words have been input and their spelling checked, the return key 15 is pressed. As a result, control shifts from S5 to S37, and the data in the line buffer 93 is transferred to the text memory 9.
2 and stored.

As explained above, according to this embodiment, when spell checking, the input word area on the LCD display 71 is divided into two, and the input word is displayed in one of the two divided display areas while corresponding to the other. Since candidate words are displayed, there is no need to take your eyes off the display position of the input word to check the displayed candidate words (this improves work efficiency when inputting sentences. Since a dedicated area for displaying is not required, the LCD display 71 can be used effectively.

In the above embodiment, the spelling of the input word is checked and the misspelled word is replaced with a candidate word. The input word may be replaced with a synonym.

Alternatively, the conjugated form of the input word (past tense, past participle form, comparative, superlative, etc.) can be searched and displayed based on commands from the conjugated form search key, and the input word can be replaced with the conjugated form. good.

Further, although the above control is performed in the memory mode, it can be similarly executed in the line-pie-line mode in which input data is printed line by line. However, in the control in the line-pie-line mode, the processing in S7 is the printing processing on the printing paper 45.

In the embodiment described above, the present invention is applied to an electronic typewriter, but it can be similarly applied to various word processors.
