Abstract

PURPOSE: To display or print characters in an easy-to-read style by specifying an overwriting mode, and then inputting symbols and characters and storing their dot patterns in a buffer memory in an overwriting style. CONSTITUTION: If an overlay judgement part 2 judges that the overlay mode is specified when a dot pattern expansion part 1 stores a dot pattern in a buffer memory 3 after expanding an inputted symbol or character into the dot pattern, the dot pattern is stored by being overwritten to a dot pattern which is already stored in the buffer memory 3. Consequently, the dot pattern corresponding to a new symbol or character represented with the specified symbol or character in the buffer memory 3 is generated in the buffer memory 3 and displayed on a display device 4. Consequently, the symbol and character can be displayed out in a symbol-character combined easy-to-read style.

Description

[Detailed Description of the Invention] [Summary] Regarding a superimposed display output method that displays and outputs input symbols and characters in a superimposed manner, symbols and character patterns are superimposed to display and output special symbols in an easy-to-read format. For the purpose of and a superimposition determination section that instructs the dot patterns to be developed in an overlapping manner, and is configured to display and output using the dot patterns developed and superimposed by the dot pattern development section.

[Industrial application field]

The present invention relates to a superimposed display output method for displaying and outputting input symbols and characters in a superimposed manner.

[Problems to be solved by conventional technology and invention] Conventionally,
A display device that displays characters and symbols input from a keyboard or the like displays only character patterns registered within the device or in an external storage device.

Therefore, for example, if you want to display a symbol such as f,
Even if you have individual patterns such as "f", "1", and "-1", it is not possible to display a combination of these, so a symbol that combines these three is registered as one new symbol. Or, you must display "1" on the top line and "-2" on the bottom line, centering on f''. In the former case, you must register a new symbol. However, in the latter case, there is a problem that the position and spacing of characters become unnatural.

An object of the present invention is to display and output special symbols and the like in an easy-to-read format by superimposing symbols and character patterns.

[Means for solving problems]

Means for solving the problem will be explained with reference to FIG.

In FIG. 1, a dot pattern development section 1 develops input symbols and characters into dot patterns and stores them in a buffer memory 3.

The superimposition determination section 2 notifies the pattern development section 1 of this fact when the superposition mode is designated.

The buffer memory 3 stores tone patterns corresponding to symbols and characters.

[Effect]

As shown in FIG. 1, in the present invention, after a dot pattern development section 1 develops input symbols and characters into a dot pattern, when the dot pattern is stored in a buffer memory 3, a superposition determination section 2 determines the superposition mode. is specified, the buffer memory 3 has already been filled in response to this notification.
The dot pattern is stored in such a manner that it overlaps the dot pattern stored therein.

Therefore, a new dot pattern corresponding to the symbol or character specified in the buffer memory 3 is generated in the buffer memory 3, and a dot pattern is generated in the display device 4.
This makes it possible to display and output in an easy-to-read format that combines symbols and characters.

〔Example〕

Next, the configuration and operation of one embodiment of the present invention will be explained in detail using FIGS. 1 to 4.

In FIG. 1, a dot pattern development section 1 develops input symbols and characters into dot patterns and stores them in a buffer memory 3. At this time, if there is a notification from the overlay determining unit 2 that the overlay mode is in effect, the dot pattern is stored in a manner that overwrites the dot pattern already stored in the buffer memory 3, that is, the dot pattern is overwritten on the dot pattern already stored in the buffer memory 3. The overlay determining unit 2 stores the results of an OR logical operation between each dot of the existing dot pattern and the corresponding dot of the dot pattern to be overwritten. , and notifies the dot pattern development section 1 of this fact to instruct it to store the input dot patterns of symbols and characters in the buffer memory 3 in a superimposed manner.

The buffer memory 3 stores dot and dot patterns corresponding to symbols and characters. The tone pattern stored in the buffer memory 3 is read out and displayed on the display device 4.
The information may be displayed on the screen, or printed using a dot printer not shown.

FIG. 2 shows an example of character patterns that are displayed and output in a superimposed manner. Figures 2(a) to 3(c) show character patterns (dot patterns) for overlapping, and Figure 2(d) shows character patterns (dot patterns) for overlapping.
shows an example of a character pattern superimposed in the buffer memory 3. In this way, individual patterns as shown in FIG.
Create and display patterns in Figure 2 (d) that combine two
By outputting, it becomes possible to display and output special symbols, characters, etc. in an easy-to-read format.

The procedure for storing data in an overwritten manner in the buffer memory 3 will be explained with reference to FIG.

FIG. 3(a) shows the case where the symbol "f" displayed at the cursor position on the display device 4 is displayed by manually pressing the key.This is because after specifying the superimposition mode, After storing a dot pattern corresponding to the manually entered symbol "f", for example "00111010" in the buffer memory 3, at a predetermined position in the buffer memory 3, it is read out and the display bag r! This is what is displayed on 14.

Figure 3 (B) shows the case where the pre-registered symbol "-3'" is displayed manually using the key under the condition shown in Figure 3 (A). The dot pattern corresponding to the symbol '-4'', for example, 11000000'',
After performing an OR logical operation with the pattern 00111010'' which is already stored in the buffer memory 3 and which is about to be overlapped, the result 11111010'' is stored in the original buffer memory 3 position, and then read out and displayed on the display device 4. This is what is displayed.

As described above, the result of ORing the dot pattern corresponding to the symbol or character to be overwritten with the dot pattern stored in the buffer memory 3 is stored and displayed on the display device 4. By doing so, it becomes possible to display and output special symbols etc. in an easy-to-read format.

Next, the operation of the configuration shown in FIG. 1 will be explained in detail using FIG.

In FIG. 4, the symbol ■ indicates a state in which it is determined whether or not a mode switching operation has been performed. If YES,
Execute ■ in the diagram. If NO, 0 in the figure is executed.

In the figure, ■ indicates a state in which it is determined whether the current mode is the superposition mode. If YES, the current superimposition mode is canceled with ■ in the figure, the cursor is moved to the next character position with ■ in the figure, and the process ends. In the case of NO, the mode is set to the superimposition mode at ■ in the figure, the character code is loaded into the buffer memory 3 at ■ in the figure, and the process ends. In accordance with the procedure indicated by (3) in the figure, the first dot pattern for superimposition, for example "f", is stored in the buffer memory 3 by the dot pattern developing section 1 in FIG.

0 in the figure indicates a state in which it is determined whether the current state mode is the superposition mode or not. If YES, the character code of the character input with @ in the figure is overwritten in the buffer memory 3, and the process ends. By following the steps in [phase] in this figure, dot patterns corresponding to symbols and characters from the second time onwards, such as “
1" and "-5" are overwritten in the memory 3.
Store inside.

If NO, normal processing is performed, that is, the dot pattern corresponding to the input symbol or character is stored in the buffer memory 3.

Through the above procedure, when the overwrite mode is specified, the dot patterns corresponding to the input symbols and characters are stored in the buffer memory 3 in an overwritten manner.

[Effects of the Invention] As explained above, according to the present invention, after specifying the overlapping S mode, Mr. B inputs symbols and characters and overwrites them in the buffer memory. special symbols and symbols that are not registered in the device.
Characters, etc. can be displayed and printed in an easy-to-read manner. This allows an operator who inputs a document to easily enter special symbols manually.
