Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a character processing device that can handle patterns (external characters) consisting of multiple types of dot configurations, and in particular, to a character processing device that can process patterns created and stored in other models with different dot size configurations. The present invention relates to a character processing device that can be typewritten.

[Prior art]

Conventional characters in character processing devices have had different dot configurations depending on the model. For example, one model only handles dot configurations in which one character has 24 dots vertically and 24 dots horizontally (hereinafter abbreviated as 24X24 dots), another model handles 24X24 dots and 32X32 dots, and still another model handles 24X24 dots and 16X16 dots. There was a variety of ways to deal with dots.

[Problems to be Solved by the Invention] As described above, when a pattern (external character) created and stored in one model is used in another model, the present invention is capable of converting the original pattern (external character) into a pattern of another model. You have to re-enter the data using the creation function, and also design and re-enter the dot configuration pattern that did not exist in the original model.
The object of the present invention is to realize a character processing device that improves the shortcomings that scanning is slow and designs are difficult to unify.

(Means for Solving the Problem) According to the present invention, there is provided an input means for inputting a character code, a search means for searching a pattern stored in a storage means based on the character code, and a pattern searched by the search means. determining means for determining whether or not the pattern is of a predetermined pattern size; a changing means for changing the pattern size if the pattern is not a predetermined pattern size according to the determining means; and a registration for registering the pattern changed by the changing means. By having the means, it is possible to easily transplant patterns such as characters.

〔Example〕

FIG. 1 shows the configuration of one embodiment of a character processing device according to the present invention.

In the configuration shown in FIG. 1, the CPU is a central processing unit in the form of a microprocessor, which performs calculations for character processing, logical judgments, etc., and uses an address bus AB and a control bus C.
B. Controls each component connected to those buses via the data bus DB.

The CPU also recognizes graphic areas in a document, determines the size and type of graphic areas, and generates figures based on the contents of the RAM, which will be described later.

Address bus AB transfers address signals that indicate components to be controlled by the microprocessor CPU. Control bus CB is microprocessor CP
Control signals for each component to be controlled by U are transferred and supplied. The data bus DB transfers data between each component device.

Next, the ROM is a read-only fixed memory, and stores control procedures by the microprocessor CPU, which will be described later, such as the procedure shown in FIG. 6.

Further, the RAM is a writable random access memory having a configuration of 1 word and 16 bits, and is used for temporary storage of various data from each component. The stored data includes registers HK that store the types of dot configurations handled by the main unit.

There are code registers CR and patterns that store the character codes of read external characters, and patterns that are being created or modified.

Other data stored includes data representing the type of DISK, which will be described later, and a register storing data representing the dot configuration of external characters stored in the DISK.

KB is a keyboard, which includes alphanumeric keys, hiragana keys, katakana keys, character symbols and symbols such as function character keys for specifying graphic areas, and keys for specifying the start and end of kanji conversion, as well as main character processing keys. It is equipped with various function keys for instructing various functions to the device.

DBUF is a buffer memory that stores document information input from the keyboard KB, an enlarged screen of a custom character pattern being created or modified, and the like.

DISK is the created document and character pattern.

This is a magnetic disk device for external storage of custom character patterns.

The DISK is a magnetic storage device as an external storage for storing fixed-form documents, custom character patterns, etc., and the porting of custom characters from other models is performed via this device.

CR is a cursor register, the contents of which can be read and written by the CPU. CRT controller CR (described later)
The TC displays a cursor at a position on the display device CRT corresponding to the address stored here.

A CRT is a display device using a cathode ray tube or the like, and a dot-configured display pattern and a cursor display on the display device CRT are controlled by a CRT controller CRTC.

The CRT controller CRTC has a cursor register CR.
and displays the contents stored in buffer DBUF on display device C.
Display on RT.

CG is a character generator, and the display device CRT
Generates character signals such as characters, symbols, and cursors to be displayed on the screen.

Note that since the content of the buffer DBUF is displayed in correspondence with the position on the display device CRT, the display is performed simply by storing document data, external character patterns, etc. in the buffer DBUF.

The character processing device of the present invention, which is composed of each of these components, operates in response to various inputs from the KB. When input from the KB is supplied, an interwoven signal is first sent to the CPU, and the CPU is stored in the ROM and outputs various control signals, and various controls are performed using these control signals.

In the character processing device having such a configuration, the external character reading means includes:
A stored external character pattern is read from a storage medium such as a floppy disk onto the memory of a character processing device. Here, this external character reading means can also read external character patterns created and stored in other models. Further, the external character storage means is a means for storing the external character pattern on the memory of the character processing device in a storage medium such as a floppy disk that is different from the one from which the external character was read. The input/output means themselves between the storage medium and the memory are simply referred to here as reading means and storage means, and are meant to perform these processes.

Next, the principle of pattern enlargement/reduction will be explained with an example. An example is 1 of n, xm, from an 8x8 dot pattern of nxm.
This is a case where a 6×6 dot pattern of 0×10 dots and nl×m is created.

In order to create a 10x10 dot pattern from an 8x8 dot pattern, it is necessary to increase the rows and columns of the 8x8 dot pattern by two dots each. The increasing position is determined in advance between the 2nd and 3rd dots and between the 6th and 7th dots of the 8×8 dots. FIG. 2 explains an example of an algorithm for inserting dots in enlarging a character pattern. To increase the number of columns, if the dot is at the left position (2nd and 5th dots) or a white dot, the dot in between is a white dot, and the left position is a black dot and above the right position (3rd dot and 7th dot). If both the row above and the row below are white dots, they are white dots, otherwise they are black dots. Similarly, for a line, if the upper position is a white point, it is a white point; if it is a black point, but both the left and right sides of the lower position are white points, it is a white point; otherwise, it is a black point. FIG. 3 is an explanatory diagram showing the process of enlarging a pattern based on the algorithm of FIG. 2.

Figure 3 (1) shows the loaded 8x8 dot pattern, Figure 3 (2) shows the area between the second and third dots in the same figure.
A row of dots is inserted between the sixth and seventh dots. FIG. 3(3) shows a row of dots inserted between the second and third rows and between the sixth and seventh rows of FIG. 3(2).

When creating a 6x6 dot pattern from 8x8 dots, it is necessary to reduce the rows and columns of the 8x8 dot pattern by 2 dots. The positions to be reduced are determined in advance, such as the third and sixth dots of the 8x8 dot. Figure 4 shows the rows of dots in character pattern reduction.
FIG. 2 is a diagram illustrating an example of a column deletion algorithm. If there is a black dot in the row of dots to be deleted, the dot at the corresponding position in the next row is checked, and if it is a white dot, the corresponding position in the previous row is set as the black dot. Similarly for lines, if there is a black dot in the line to be deleted, check the dot at the corresponding position on the next line, and if it is a white dot, set the dot at the corresponding position on the previous line as the black dot. . FIG. 5 is an explanatory diagram showing the process of reducing a pattern based on the algorithm of FIG. 4.

FIG. 5(1) shows the read 8×8 dot pattern. FIG. 5(2) is obtained by removing the third and sixth columns of FIG. 5(1).

FIG. 5(3) is obtained by deleting the third and sixth lines of FIG. 5(2).

The above configuration will be explained with reference to FIG.

In step S1, a custom character pattern and a character code for one character are read from a custom character pattern stored at a predetermined address on a storage medium such as a floppy disk. In step S2, it is determined whether or not all external characters have been read based on which address has been read. If all are read, the process ends. In step S3, the CPU
checks the type of the number of constituent dots of the read external character pattern by comparing registers HK and K, and if it is the same as or greater than the type of the number of constituent dots used at the read destination, the process advances to step S8. If the types of the read (external character) patterns are insufficient to the types of the read destination, the process advances to step S4 to create a pattern with the insufficient number of constituent dots. Step S
In step 4, it is checked whether the missing pattern can be created by enlarging the read pattern.

If there are 8x8 dots but no 10x10 dots, you can create one by enlarging it, so go to step S5.

In step S5, the read pattern is enlarged,
Create the missing pattern. At this time, the missing pattern is 2f! If there are more than class i, enlarge each one and create a pattern.

That is, the corresponding character pattern is accessed from the disk DISK and stored in the buffer B1 on the memory RAM.

Next, in order to enlarge the pattern developed on the buffer B1 of the memory RAM, the 8×8 pattern of the buffer B1 is processed as shown in FIGS. 2 and 3, and the memory R
Expanded to buffer B2 on AM.

When the instruction for enlarging processing is determined, it is determined in step S4, and pattern enlarging processing is executed in step S5 according to the procedure and determination described above, and the buffer B2 of the memory RAM is
is memorized.

Next, in step S6, it is checked whether the missing pattern can be created by reducing the read pattern. If there are 8x8 dots but no 6x6 dots, it can be created by reducing the size, so go to step S7. In step S7, the read pattern is reduced to create a missing pattern. At this time, if there are two or more types of missing patterns, each is reduced and a pattern is created.

The CPU determines reduction in step S6, and then proceeds to step S7.
Then, the 8×8 dot pattern in the buffer B1 of the memory RAM is converted into a 6×6 dot pattern as shown in FIG. 4.5 and stored in the buffer B3 of the memory RAM.

Once the missing pattern is captured in this way, it is stored in the read destination or another storage medium together with the character (external character) code of the register CR in step S8. This completes the printing of 8 patterns for one custom character, so go to step S1 to read the next custom character.

That is, in step S8, the CPU determines whether the created pattern or the appropriate pattern should be registered;
If support for registration comes from keyboard KB, register CR
character code or newly set character code (
Step S9 to the disc set based on CR).
memorize it.

When this process is completed, the process moves to step S1.

In the example, enlargement/reduction is performed from reading external characters.

The system continues to memorize characters until there are no more foreign characters to read, but the user can choose to read, enlarge, reduce, and memorize one character at a time, and has also added a means to modify the created pattern. It is also possible to create a custom character.

The enlarging/reducing algorithm is just one example, and may be replaced with another algorithm deemed appropriate.

Also, even if the number of constituent dots is different in length and width,
You can apply each algorithm.

Furthermore, in the example, only the case of reading external characters created on other models is possible, but by changing the storage means so that they are stored in the storage medium of other models, it is also possible to print 8 external characters on other models. be.

In the embodiment, enlarged/reduced patterns are also stored, but among the read patterns, only the patterns with the reference number of constituent dots are stored, and missing patterns can be enlarged/reduced as necessary. It is also possible to create and use it using a reduction means.

〔effect〕

As explained above, by providing the pattern enlargement/reduction means, it has become possible to transplant external characters at once without the user having to input missing patterns one character at a time.

Furthermore, the created pattern is based on a certain algorithm, so it is consistent with other character patterns. Therefore, even when modifying a created pattern, compared to inputting one character by character by the user,
Now there are fewer parts to modify.
