Description

[Detailed Description of the Invention] [Summary] Conversion of the character angle of a dot character pattern in a character display device, and the flyback time that occurs when signals of each column are sequentially transmitted from the right side of the dot character pattern. A method of converting a pattern to a specified angle using .

[Industrial application field]

The present invention relates to a method for outputting a dot character pattern output from an electronic computing device in a reversed left/right or up/down direction. Only regular characters are used.

However, as the use of electronic computing devices has expanded to a wide variety of fields, it has become inconvenient to express cutlery using only conventional fixed-form characters, and there has been a demand for rotated character patterns in which the horizontal or vertical directions are reversed. However, conventional methods generally involve separately creating character patterns in an offline method, and there has been a need for a method that can be created offline as needed.

In addition, with the spread of computer typesetting machines, printing is done on a display, and at the same time formatting is done to grasp the image, but even if rotated characters are used due to typesetting requirements, regular characters are usually used. Generally, a method is adopted in which the characters are displayed on a display, a function is input, and rotated characters are printed out at the time of printing.

Therefore, considering the original purpose of formatting, there is a need for a character pattern angle conversion method that can easily convert regular characters into rotated characters and display them on a display device.

[Conventional technology]

When converting the angle of a dot character pattern used in an electronic computing device and displaying the rotated character pattern on a display device or printing it out, the following method has conventionally been used.

(1) An application program method in which the angle conversion of a character pattern is processed within the application program and a rotated character pattern is created from a stored dot character pattern.

(2) A unique character pattern method in which a character pattern rotated 90 degrees or 180 degrees left and right is specially created, registered in a special area of a storage device, and used as a special character.

(3) In addition to (1) and (2) above, in the stroke dot method in which character pattern data is stored in a vector method, the horizontal stripe information of the vector is converted according to the rotation angle,
There is a vector data conversion method that creates a rotated character pattern at any angle.

[Problem that the invention seeks to solve]

However, all of the above methods require complicated processing and time.
The cost is high and it is not suitable for application to low-cost equipment.
It has the following problems.

(1) In the application program method, a purpose-specific application program is developed and a rotated character pattern is included as a part of the application program. Therefore, it cannot be said that it is a method for easily creating a rotated character pattern, and it has the disadvantage that it takes a long time to prepare.

(2) The unique character pattern method extracts regular characters that require rotated characters from the storage device, converts the scanning direction of the character pattern according to the rotation angle, and then converts the completed rotated character pattern to the original character. Regarding the method of assigning a distinct code and registering it in a special area of the storage device for use,
This must be carried out off-line using a program for converting the scanning direction of the dot character pattern, and requires additional processing time on the electronic computing device.

In addition to the above method, a method is also used in which a rotating character pattern is designed in dots and entered and registered using a card input format or a graphic reader, but either method takes a long time when the number of characters is large. The cost will be high.

(3) The vector data conversion method has the feature that it is easier to operate and can create rotated character patterns faster than the above (11) (21) if a dedicated program is installed, but the disadvantages of the vector data conversion method are Although the conversion of vertical and horizontal position information is fast, it is necessary to convert the vector pattern to a dot pattern and fill in the inside of the character before outputting the character, which increases the overall processing time.

Furthermore, this method is limited to devices that employ a vector method, and cannot be applied to character display devices that store dot character patterns as they are in a storage device.

As described above, the conventional method requires a long time to prepare, the work is complicated, and the cost is high, and there are problems that it cannot be easily applied to arbitrary characters.

The present invention aims to solve these problems and provide a method for easily creating rotated character patterns.

[Means for solving problems]

FIG. 1 is a diagram explaining the principle of angle conversion of a dot character pattern according to the present invention.

As shown in FIG. 5(a), when the dot character pattern 1 representing the kanji "upper" is accessed, signals are sent in the order of character pattern strings A1 to A, . In other words, the same figure (
First, like bl, the character pattern address 3-1 in column A1
The signals are sent in the order of ~N, and this signal sending time A +
Following T, the signal in the A2 column is also the same as the A, T time.
will be sent within the time. A flyback time FT occurs while the signal moves from the At column to the A2 column, and the signal for each column sequentially changes to A. It is sent out until it reaches the column.

Here, the flybank time FT is idle time from the perspective of data processing. The present invention makes effective use of this free time, and sequentially stores the signals 1 to N of character pattern addresses 3 in the storage device in the replaced state on the right end surface of the rotating character pattern row 4 within each free time. This is a method of storing the characters and creating a new rotated character pattern 5.

As described above, the present invention provides a method of creating a rotating character pattern by utilizing the idle time in the fly bank, which was originally left unattended. This problem is solved by processing the conversion of .

[Effect]

In the dot character pattern 1 of FIG. 1(a), a signal is sent in the direction of character pattern addresses 3 1 to N every time A I""' A of the character pattern string 2. The flybank time FT shown in the figure (b) occurs when the signal transmission of the A8 column of the character pattern string 2 is completed and the signal is transferred to the A2 column. Using this time, the data of the dot character pattern is replaced in the storage device with the angle of the dot character pattern converted.

That is, as shown in the schematic example of the rotated character pattern 5 obtained by converting the angle from the dot character pattern 1, the data in the direction 1 to N of the character pattern address 3 is converted into the rotated character pattern string 4.
By newly storing the character pattern in the storage device in a state in which the character is replaced with the right end face of the character, a character pattern whose angle is converted to the right 90 degrees can be created.

〔Example〕

FIG. 2 is a circuit block diagram for creating a rotated character pattern according to the present invention.

Create rotating character patterns using Character Generator 2
Select the character that requires angle conversion from among the characters stored in 3, and store the code of that character in code register 2.
Enter 1.

Further, as shown in the side view of character pattern address replacement in FIG. 3, dot-based rotation address data 31 corresponding to the angle conversion of the character pattern is input into the code register 21 in advance.

The line counter 22 reads a regular character pattern from the character generator 23, replaces the data in accordance with the angle conversion of the rotary address data 31 input to the code register 21 within the fly bank time FT, and stores the data in the shift register 24. Store.

When the data replacement is completed, the CPU (Central Processing Unit) 25 starts reading out the data and outputs it on the screen of a display device or as printed matter.

In this way, for example, the character pattern for "above" shown in (a) of Figure 4 can be changed to a pattern of 90 degrees to the right (b), a pattern of 90 degrees to the left (C), or a pattern reversed to 180 degrees (angle like dl). is arbitrarily converted and displayed as a rotated character pattern.

〔Effect of the invention〕

As described above, according to the present invention, rotated character patterns can be created extremely easily from fixed character patterns stored in an electronic computing device.

What's more, the effective use of flyback time, which was conventionally left as idle time, means that the computer processing time required to create a rotating character pattern can be reduced to virtually zero time. , and the economic effect is also excellent.

Furthermore, this method can be easily added to a conventional device as an extended function, and is extremely effective in practice.
