Abstract

PURPOSE:To improve the operability by retrieving the content of modifier data for character data above and below a data input position based on data in present position memory and data memory, and allowing modifier data of the same content as character data to be stored in data memory together with the character data, if the modifier data is of the same content as the character data. CONSTITUTION:Entered character data and modifier data are stored in data memory as a pair using an input device. In addition, the entered character data is output to an output device in accordance with a data entry position indicated by an input position indicator device. Further, a retrieval device retrieves the content of modifier data in data memory corresponding to a character position above and a character position below data entry position, based on present position memory which stores a data entry position as the present position, if character data is entered by the input device. As a result, the modifier data is stored in data memory together with character data, if the modifier data corresponding to the character position above and below the data entry position is of the same content as the character data.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document creation device, and more particularly, to a document creation device that simplifies document creation and editing operations.

[Prior Art] Conventionally, in document creation devices such as typewriters and word processors, data corresponding to the erroneous character is deleted from the line buffer by operating a delete key for erroneous characters in a document, and erroneous printing on printing paper is also erased. Some were equipped with an autocorrection function that erased characters or incorrectly entered characters on the display device.

In addition, some had a bold mode for outputting input character data in bold, an auto underline mode for automatically adding an underline to character data, and the like. In this case, bold output data and underlined data are also stored in the line buffer along with character data.

[Problem to be solved by the invention] However, in the document creation device, for example,
When the operator enters multiple character data with bold mode and auto underline mode set and finds an incorrect input in the character-modified input character data after canceling both modes, the operator By moving the cursor or print head to the position of the erroneously input character and operating the erase key, the corresponding data is deleted from the line buffer and the erroneously input character is erased from the printing paper or display device. By resetting both modes and inputting correct character data, the character data and the modification data corresponding to the set mode are stored in the line buffer. Furthermore, the operator had to move the cursor or print head to the input position before starting the correction operation by operating a relocate key or the like, and then cancel both modes again.

Therefore, these correction operations are extremely complicated and burdensome to the operator.

The present invention was made in order to solve the above-mentioned problems, and by simply inputting correct data, it is possible to input characters that are the same as the characters on both sides without worrying about the modification status when inputting correction data. It is an object of the present invention to provide a document creation device that is extremely easy to operate and is capable of adding character decorations.

[Means for Solving the Problems] In order to achieve this object, the document creation device of the present invention includes an input means for inputting character data and character modification data corresponding to the character data, and input means for inputting character data and character modification data corresponding to the character data. an output means for outputting input character data, an input position indicating means for indicating the data input position on the output means, and a current position for storing the current position of the input position means. a position memory, and searches for the contents of modification data for upper and lower character data of the data input position based on data in the current position memory and data memory when character data is input from the input means. and control means for storing the same modification data in the data memory together with the input character data when the higher and lower modification data are the same according to the search result of the search means. .

[Operation] The present invention having the above configuration stores character data and modification data inputted by the input means in a data memory as a pair. Furthermore, the input character data is outputted onto the output means according to the data input position indicated by the input position indicating means.

Furthermore, when character data is inputted by the input means, the retrieval means is configured to search for characters corresponding to upper character positions and lower character positions of the data input position based on a current position memory that stores the current position of the data input position. Search the contents of qualified data in data memory. As a result, when the modification data corresponding to the upper and lower character positions are the same, the modification data is stored in the data memory together with the character data.

Further, the liquid crystal display 75 forms part of a display mechanism described later, and is connected to the keyboard 3 or the RAM 50 described later.
You can display multiple lines of data from.

Next, the overall configuration of the control system of the word processor will be explained based on the block diagram of FIG.

The word processor 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, display mechanism are connected to the main CPU of the control device C ( central processing unit) 39
It is connected to the.

The control device C includes a main CPU 39 and its main CPU 3.

The program memory 41 of the ROM 40 includes the keyboard 3.
A control program for controlling the printing mechanism PM and display mechanism in correspondence with code data input from each character key and various function keys, a control program for correction control to be described later, and the like are stored.

The RAM 50 includes a current position memory 51 that sequentially updates and stores the current position of the carriage 22 (print head) from the absolute origin in correspondence with the print position, code data such as printed characters, underline flags, etc. A print data memory 5 that stores approximately 500 characters of attribute data consisting of character modification data such as bold flags and carriage movement amount data in 2-byte correspondence with print positions.

Pointer 53 and main CPU 3
Various types of memories and the like are provided for temporarily storing the results of the arithmetic processing performed by the computer.

Based on the control program, the main CPU 39 causes the printing mechanism PM to print characters and symbols corresponding to the data input from each character key 10, and sequentially stores the print data in the print data memory 52 in correspondence with the print position. .

Furthermore, when the erase key 12 is operated, the main CPU 39
is the data of the current position memory 51 and the print data memory 5.
Based on the data of No. 2, the printed characters 27 identical to the printed characters are struck by the printing mechanism PM via the correction ribbon 29 to be erased. In this case, the print head is struck once at the current position, then struck once at a position where the print head is slightly moved, for example, 1/240 inch in the printing direction, and then the print head is moved from the current position in the direction of the gray medium character. Erasing is performed by striking once at a position slightly moved by 1/240 inch, for a total of three strikes.

The display mechanism includes an interface 70 and a display CPU 7.
1, a character generator 72, a display controller 73, and a liquid crystal display 75, which are connected as shown.

The character generator 72 has a liquid crystal display 7.
Approximately 400 types of dot matrix display data for displaying characters and symbols are stored in correspondence with the code data.

The display CPU 71 reads out display data corresponding to the command data and character data output from the main CPU 39 via the interface 70 from the character generator 72 and outputs the display data to the display controller 3. . The display controller 73 writes display data into the display RAM 74 and at the same time outputs a display signal corresponding to the display data to the liquid crystal display 75. Furthermore, the display CPU 71 also performs cursor movement control that instructs the display controller 73 of the address to which the cursor should be moved, in response to cursor movement data from the main CPU 39 via the interface 70.

Next, the correction processing control performed by the word processor control device C when the typewriter mode is set will be explained based on the flowchart of FIG. 4.

When the word processor 1 is powered on, this control starts, moves to step Sl (hereinafter simply referred to as Sl, and other steps are handled in the same way), initial settings are executed, and S
2, it waits for a key input. Then, when a key is input, the process moves to S3, where it is determined whether the erase key 12 is pressed, and when the erase key 12 is operated, the result of the judgment at 83 becomes Yes, and the process moves to S4. In S4, the data in the current position memory 51 is written to the print data pointer 53, and the data in the print data pointer 52 is written based on the data in the print data pointer 53.
The data at the address corresponding to the print head position is read out. Then, in the next step 85, it is determined whether the data is print data or not, and if it is print data, the process moves to S6. In S6, an erasing operation is performed based on the read print data (including underlined data), that is, character data and character modification data. Then, in the next step 87, a space code is written to the address of the print data memory 52 corresponding to the erased character data, and all character modification flags corresponding to the print data are reset. That is, the erased print data is erased from the print data memory 52.

When it is determined No in S5, for example, if the read data is a space code, the process moves to S8, the print head is moved by one character in the direction of the gray medium character, and the value in the current position memory 51 is decremented. At the next step 89, the data of the current position memory 51 is written to the print data pointer 53, and based on the data of this print data pointer 53, the data of the address corresponding to the print head position of the print data memory 52 is read out. . Then, in the next step 810, it is determined whether or not there is print data, and if there is print data, the process moves to S6. Further, when there is no print data, for example, when it is the first data in the print data memory 52, the process moves to S11, an alarm process such as sounding a buzzer is executed, and the process returns to S2.

On the other hand, when the character key 10 or the space key 11 is operated, the determination result in S3 becomes No, and the process moves to S12. Then, in S12, the result of determination as to whether the operated key is the character key 10 or the space key is Yes, and the process moves to 813. In S13,
Print positions on both sides of the print position facing the print head,
In other words, the data at the addresses of the print data memory 52 corresponding to the adjacent left and right print positions are read out, and the RA
It is stored in the work memory in M50. In the next step S14, it is determined whether the character modification data (character modification flags) of the two read data are the same. If the character modification data of adjacent print position data is the same, S
15, the character data (character code) corresponding to the operated character key or space key and the character modification data of the adjacent print position are printed at the print head position based on the work memory. The data is stored at an address in the data memory 52. Then, in S16, printing processing is performed based on the printing pattern stored in the printing data memory 52. At this time, the main CPU 39 outputs control signals to each drive circuit of the printing mechanism PM. Subsequently, in S17, the print head is moved by one character in the printing direction, and the value in the current position memory 51 is incremented.

On the other hand, if the determination result in S14 is NO, that is, if the character modification data of each data in the adjacent print position is not the same, the process moves to S18, and character modification is performed based on the character modification mode currently set in the word processor. The data and the character data corresponding to the operated character key or space key are stored in the address of the print data memory 52 corresponding to the print head position. Then, the process moves to S16 to perform the printing process, and then in S17 the print head is moved by one character in the printing direction, and the process returns to S2.

In the above embodiment, a case was explained in which printing is performed on printing paper in the typewriter mode (direct print mode) of the word processor 1. It may also be a case where processing is performed.

That is, basically, the correction processing control is almost the same, so to simplify the explanation, the print head (carriage) as the input position indicating means in the above embodiment is used as the cursor, and the printing mechanism as the output means The PM is used as a display mechanism, the printing paper is used as a liquid crystal display 75, and further,
By replacing the RAM 50 as a data memory with the display RAM 74, the same functions and effects as in the embodiment described above can be obtained.

In addition, in the above embodiment, when reprinting after erasing a printed character, if the character modification data of the printing positions on both sides adjacent to the printing position do not match, the character modification data set in the word processor at that time is automatically deleted. Although the character modification data is stored in the print data memory based on the modification mode, it is also possible to notify the operator that there is no match.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, when a character is input again after erasing an incorrectly input character, the character can be inputted again without worrying about the character modification state for that character. , it is possible to provide an extremely easy-to-operate document creation device that can give the same character decoration to the characters on both sides just by operating the correct character key.
