Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a display device or a printing device that displays or prints characters in which various character sizes with different numbers of dots coexist. The present invention relates to a method for processing data containing a mixture of various character sizes, which is divided into unit sizes of 1 and 2, and is used for hardware processing to display busyness or print processing.

[Conventional technology and problems]

In display devices or page printer devices that print on cut form sheets of sizes such as A4, 85, etc., printing with different numbers of dots, such as 24 x 24, 3
When various character sizes such as 2X32 and 40X40 dot matrices are mixed, if the number of character digits per line and the number of lines per page are fixed, the line length and the width between lines will also change, so You will need to adjust the number of lines and digits accordingly.

Therefore, in a screen (page screen) that manages rows and columns, the concept of rows and columns breaks down, and it becomes extremely difficult or complicated to implement it on the hardware side. .

Conventionally, as a data processing method where various character sizes are mixed, dot data for one screen (one page) is owned,
Among them, there is an image-like processing method for drawing various characters,
There is a processing method that uses hardware, for example, a counter, to manage the distortion of the concept of lines and columns due to the mixture of various character sizes. However, the former method requires a large amount of dot memory for one screen (one page), resulting in a significant cost reduction and a disadvantage in that the processing speed is significantly reduced. . On the other hand, the latter method has the disadvantage that rows and columns are managed by hardware, resulting in complicated logic, which increases costs, and makes it impossible to respond flexibly to changes in specifications.

[Purpose of the invention]

The present invention eliminates the above-mentioned drawbacks, and provides a method for processing data in which various character sizes are mixed, which can process data in which various character sizes are mixed, using simple logic and with a small amount of hardware. The purpose is to

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the hardware configuration to which the present invention is applied, and FIG. A (This is a diagram showing an example of conversion to a buffer. In the diagram, 1 is a screen buffer, 2 is an MPU (microprocessor), 3 is a conversion buffer, 4 digits CG (character generator),
5I-i matrix counter, 6IdP/S (parallel/serial) conversion! , 71d serial interface control circuit, 8 to 10 are selectors, information stored in the D1i1I buffer, and D2 information stored in the conversion buffer.

In FIG. 1, display information containing a mixture of various character sizes is transferred from a host computer (not shown) to a serial interface, and is stored in a screen buffer 1 through a serial interface control circuit 7. The format of the display information stored in the screen buffer 1 is such that a character size is added to each character code, as shown in IA shown in FIG. According to the present invention, when there are dots that are the greatest common divisor of various character sizes, for example, a character size of 24 x 24 dots and a character size of 32 x 32 dots, the dots are divided into 8 dots as one unit, and this 1 unit 1
It is processed as a digit. For that purpose M P tJ
2, the data stored in the screen buffer 1 is sequentially read out and divided into units according to the character size, as shown in D2 in FIG. The character size of the dot is divided into four parts, a character position designation flag is added to each unit, and the character code to which the character size designation flag and character position designation flag are added is re-edited in the conversion buffer 3. If the size is 24 x 24 dots, the character position specification flag is rooj for the left part of the character, ro IJ for the middle part of the character, and r for the right part of the character.
l OJ, in the case of 32x32 dots, the left part of the character is ro
OJ, the character in Chubu is ro IJ, the character Fuchu is ``10''
", and the right part of the character is defined as "11". The CG4 has character patterns of each character size corresponding to the character code, and it is also possible to register the character pattern through the data bus by tracing the address from the MPU 2 to the selector 10. . When displaying display information stored in the conversion buffer 3, when the node is activated, the conversion buffer 3 is sequentially accessed with the minimum unit of 1 row and 1 digit, and each character size and A character pattern is read out from the CG 44 using the character code as an address according to each character position. At this time, the matrix counter 5 counts the number of rows and digits, and the matrix counter 5 counts the number of rows and digits, assuming that the minimum unit of the conversion buffer 3 is one row and one digit. The character pattern read out from CG4ρ is

The data is converted into realistic dot data and sent to the display section CRT. The display output of "Kan" shown in Figure 2 is 2
This is an example of characters with sizes of 4 x 24 dots and 32 x 32 dots, and the display output of "characters" is 24 x 24 dots.
This is an example of the size of characters. In FIG. 2, only the digit direction is divided into minimum units for simplicity, but in reality, the row direction is also divided into minimum units. As is clear from Figure 2, when divided into the minimum unit of 8 dots, 24×2
Consists of 4 dots for "Kan" and 1d 3 digits for "character", 32X
It consists of 4 digits of 32 dots. Although the above description has been about display output, the same applies to print output. Figures 3 and 4 are diagrams showing an example of the flow of processing by a microprocessor in a printing device to which the present invention is applied. Figure 5 shows an example of a processing device in which print data sent in JIS code is divided and edited into unit sizes and stored in a conversion buffer.

The following describes the processing by the microprocessor (MPU) when print data is sent from the main unit and is directly divided and edited, stored in the conversion buffer, and then printed using a configuration that eliminates the screen buffer. The flow will be explained with reference to FIGS. 3 and 4. The print data is, for example, formatted data as shown in FIG.

〔Effect of the invention〕

As is clear from the above explanation, according to this company, even if various font sizes with different numbers of dots are mixed, information is stored by re-editing the size of the greatest common divisor of the various font sizes.

It is possible to display or print data with a mixture of various character sizes with a very simple circuit configuration.
