Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document processing device that edits documents, and particularly to a document editing device that enables format change processing when special characters or codes are input. It is.

[Prior Art] Conventionally, in thermal transfer printers, the printing format and character width are not determined by the print on the printing medium as in daisy printers, but by converting or referencing the printing font using software. , it is possible to take various printing forms. To increase the expressive power of printing, there is a function that enlarges the font vertically and horizontally, such as quadruple-width characters, and executes printing.

(Question B to be solved by the invention) However, when creating a document using enlarged characters, it is often used for the first character of the document or the first character of each chapter and section 1. In this case, When changing from an enlarged character input line to the next line, the user must use the space key to move the carriage to the unprinted area and then print. This requires a very tedious task of carefully inputting the information.

Further, as an example of display processing, there is a case where a document is permanently stored and this document is edited. In this case, usually
Users take measures to avoid special character input areas such as the enlarged characters by using an indentation function or a permanent spacing function. however,
In areas avoided by these methods, there are serious problems such as misalignment due to maintenance work on the previous line, and enlarged characters and characters on the next line overlapping.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a document editing device that can automatically avoid areas used by inputting enlarged characters or enlarged symbols, thereby reducing the burden on the operator.

[Means for Solving the Problems] A document editing device according to the present invention includes an input means for inputting an enlarged character or an enlarged code, and a method for subtracting the input area width of the enlarged character or enlarged code from the current margin width. , and format changing means for automatically setting the input possible area width from the next line.

[Function] According to the present invention, when inputting enlarged characters, etc., the input area width from the next line is automatically set by subtracting the input area width of the enlarged characters, etc. from the current margin width. By providing a format changing means, the area used for inputting the enlarged characters etc. can be avoided.

[Example] Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram illustrating the electrical configuration of an embodiment of the present invention. In the figure, a CPU (central processing unit) A plays a central role in the process in this embodiment, and is connected to other elements by a system bus B.

The input means C is a keyboard, and characters are input by pressing each character key. Further, the special character specifying means is a character width switch on the keyboard, and in this embodiment, a slide switch having three positions is used. These positions allow the specification of normal width characters, 9x width characters, and 4x width characters, respectively.

Document memory E is a random access memory that encodes input characters and stores them as document data.
After inputting, it is configured so that it can be edited on the screen and the document stored in the tree document memory can be printed in reverse.

The multi-format setting means F is provided to change the print area such as margins and tabs during registration and editing of the document, and reduces the print area to free up space for graphs, drawings, etc. Alternatively, it is a means used to change the format of the document itself by changing the paper or pitch.

The display device G is used for editing the document memory E. In this embodiment, CPU units for 80 columns x 25 rows are used.

The printing device H is used for printing the document memory E and for immediate printing when a key is input.

FIG. 2 shows the printing section of the thermal printer used in this example. In this figure, a recording sheet 2 backed up on a platen 1 is configured to be recorded by a recording head (thermal head) 4 mounted on a carriage 3.

The platen 1 in FIG. 2 has a roller shape and is designed to also function as a sheet feeding roller. The carriage 3 has a guide shaft 5 installed parallel to the platen 1.
A stepping motor (carriage drive motor) 6. Drive pulley 7, driven pulley 8
, and a timing belt 9 wound around these pulleys and coupled to the carriage 3. A ribbon cassette 11 for feeding an ink ribbon 10 between the thermal head 4 and the sheet 2 is replaceably mounted on the carriage 3.

A printing pattern forming means configured by arranging a plurality of electrothermal transducers such as heating resistors is provided on the front surface of the thermal head 4, and the thermal head 4 sends the ink ribbon 10 and the sheet 2 to the carriage 3. through pulley 1
The ink ribbon 10 is mounted so as to be driven to swing between a head down position where the ink ribbon 10 is pressed against the ink ribbon 10 and a head up position where the ink ribbon 10 is retracted from the ink ribbon 10.

Further, when the carriage 3 is moved in the head-down state, the ink ribbon 10 in the ribbon cassette 11 is wound and driven in synchronization with the movement of the carriage.

During recording, the thermal head 4 is moved in a head-down state, the ink ribbon 10 is fed in synchronization with this, and recording is performed while driving the electrothermal transducer of the head based on print data. , arrow F on sheet 2
Pitch forward in the direction and start a new line.

A thermal transfer recording apparatus control system suitable for carrying out the present invention will be described with reference to FIG. In the figure, the control circuit of the recording device transmits input from the keyboard to a central processing unit (CPU) 20.
Control signals from the carriage drive motor 6, sheet feed motor 23 . The ribbon winding motor 16 and the head up/down motor 24 are driven. Further, the driver 22 is a CPU 20
Based on the print data signal received from the thermal head 4, a plurality of electrothermal transducers of the thermal head 4 are driven to generate heat, and operate to form a predetermined print pattern on the sheet 2.

Further, in this embodiment, eight font characters are provided for printing for each character key specified by input from the keyboard 21, and beautiful printing corresponding to each character pitch is realized. This font character is stored in character generator read-only memory CGROM2.
5, and the CPU 20 extracts a corresponding character printing pattern from the character code input from the keyboard 21, and drives a plurality of electrothermal transducers of the thermal head 4.

The editing process of the thermal transfer type electronic typewriter implementing the present invention will be explained using the flowcharts of FIGS. 4 and 5.

In FIG. 4, process 1 carries out a process of taking in key data from the keyboard. A key pressed by the user is input as a key signal. Depending on the type of key, if it is a carrier return key in process 2, the process branches to process 17 in FIG. 5, which will be described later.

In process 3, it is determined whether quadruple angle is specified, and in process 4, it is determined whether or not it is canceled. These processes 3 and 4 branch to process 15, but in process 15, it is determined whether the currently input character or the character to be input in the future is a double-width character. The processing is performed by exclusive ORing the instruction flags for the execution. That is, in process 5, it is checked whether the instruction flag is set, and if it is set, the process proceeds to quadruple-width character processing 6.

In process 6, the character width is calculated, and the Xl+ shown in Figure 6 is calculated.
Perform position indexing such as X2. It is determined in process 7' whether the position is within the margin and the desired input is possible, and if it is not possible, an error is notified to the user in process 16.

If it is determined in process 7 that printing is possible, control proceeds to process 8. Here, the horizontal position used by inputting quadruple-width characters, that is, xl and x in Figure 6
The 2nd class position is being updated. In other words, P in Figure 6
The horizontal position of l will be memorized.

In process 9, display processing of quadruple-width characters is performed, and in process 10, writing to the document memory is performed.

Processes 11 to 14 are processes for performing the above-mentioned quadruple-width character processing as normal character processing.
A branch is made so that the double-angle position update process is not performed.

FIG. 5 shows a processing flow when the process is branched in the process 2 and the depression of the carrier return key is recognized. In process 17 in the figure, it is determined whether there is a quadruple-width character input at the current beginning and the format needs to be changed, and the horizontal position and left margin updated in process 8 are Determine whether the positions are equal or not, and if they are equal,
No need to change the format, if they are not equal,
It has been determined that a format change is necessary.

In process 18, a margin is changed, that is, a format is created in which the input position of the line after the carrier return is changed. This format is similar to a normal format change, but because it does not involve display, the MSB (maximum significant bit) is turned on for the left margin recording area and the LMGO value in Figure 6. .

In process 19, the format change data created in process 18 is recorded in the document memory as a multi-format.

FIG. 8 is a diagrammatic representation of the area of the document memory, and represents the structure of one document data. In this figure, the original form part OFM is always set at the beginning of each text, and its format has exactly the same structure as in FIG. 7.

Also, the text part TXT in the figure is a document data recording part, which starts with the start code FO and ends with the end code F1.
It ends with. In other words, the multi-format and quadruple-width format are included in this document data recording portion.

Furthermore, these multi formats have start code EO.
, and end code E1 to declare the start and end of the process to simplify the process.

After writing the format in step 19, the screen is redisplayed. Here, the screen is scrolled horizontally and vertically, the line counter is updated, etc.

Furthermore, in step 21, the cursor is moved to the beginning position of the multi-format.

When CRI in Figure 6 is input, the cursor position is P
It will be set at the position l. Furthermore, in order to complete the quadruple-width line feed processing, the quadruple-width horizontal position is reset in step 22. This is to determine whether or not the format needs to be changed in process 17. Therefore, in the reset operation process 22, the value of the left margin position and LMG are inserted as they are in the horizontal position. I'm doing it.

This makes it possible to move the cursor to position P2 in the carrier return operation of CR2 in FIG.

The carrier return operation process for normal characters is process 1.
7, it is determined that it is a carrier return for the normal character input line, so there is no need to update the input position for the next line, and the cursor is moved to the left margin position in the same way as in step P2. In process 24, the screen is redisplayed and the cursor is moved to the left margin position.

After the above-described processing is completed, the process returns to process 1 and corresponds to the next character input. Through this process, the appropriate line break position for the next line for inputting quadruple-width characters is automatically determined,
Moreover, because this method is realized by using the multi-format setting processing of document editing devices such as current electronic typewriters, there are no technical problems or cost increases associated with it. .

Example 2 In the first example described above, the format for specifying the range of the special area is different from the normal multi-format, and the display device used in the first example is a character display. Therefore, if an expression similar to the multi-format is implemented, there will be spaces between lines in the special area. Alternatively, the character string input on the same line as the special area will be expressed on the next line. For this reason, the format data developed when changing the format according to this embodiment is not displayed on the screen.

This poses no problem for the operator and is a solution to the above problem, but if the hardware problem is an editing device that has a display device other than a character display, the special area It is also possible to display a format for specifying a range, and the expression becomes more attractive, especially if the device is equipped with a dot refresh type LCD and CRT. Furthermore, if color expression is used, the appeal to the operator will further increase. However, these high-performance LCDs and CRTs
When using , a high-definition device is required, and a high-speed CPU, display driver, and RAM are required.

Example 3 In Example 1, in order to not display the format for specifying the range of the special area, the maximum value bit in the left margin area is turned on as shown in Figure 7, so that it is not displayed. Define things systematically,
We achieved this.

This means that the resolution in Example 1 is 173 in the printing device.
Since the size is 60 inches (360 dots per inch), even if the maximum value was expressed, the MSB was empty, so this could be used, but as shown in Figure 9, an area is set at the beginning of each format, It is also possible to express whether the format is to be displayed or not. However, if effective use of memory is considered, the first embodiment is more reasonable.

Embodiment 4 In Example 1, a double-width character was taken as an example, and the special area declaration was made by an instruction from the keyboard, but the instruction may be made by means other than the keyboard. That is, if input from an image reader, input by line scan, etc. are used as instruction means, and scanning data subsequently transmitted by these instruction means is used as each data, automatic format change, which is the gist of the present invention, will also be possible. Moreover, its usability will also be expanded. In this case as well, it is necessary to have an image processing and editing function that can handle the scanning data.

As explained above, in the embodiment of the present invention, when an input instruction such as quadruple-width is declared by the special character input instruction means,
By using the multi-format setting means and changing the editing area, the operator is freed from the troublesome work and consideration required to secure space for inputting enlarged characters or adding drawings, etc. It becomes possible to do so. It is also possible to prevent the area from shifting due to character insertion or deletion when editing a registered document.

[Effects of the Invention] As described above, according to the present invention, it is possible to automatically avoid areas used by inputting enlarged characters or enlarged codes, thereby reducing the burden on the operator.
