INDUSTRIAL APPLICATION FIELD The present invention relates to a character pattern transfer control method for converting character codes output from an information center into character patterns and transmitting the converted character patterns to an output device.

In recent data communications, information centers built by general-purpose computers with database functions are connected to a large number of terminals, and information centers provide text and graphic information in response to requests from the terminals. Conversational information and communication services with interactive communication functions are becoming increasingly popular. This terminal includes a personal computer type terminal using a personal convenience store, a facsimile machine, and the like. Among these, when using a facsimile as a terminal, encoded data (character code) processed by the computers that make up the information center.
It is necessary to convert the image into a facsimile image signal (character pattern).

Additionally, there is a demand for information to be provided more quickly in response to information requests from each terminal.

BACKGROUND OF THE INVENTION FIG. 4 shows a block diagram of a conventional character pattern transfer control system.

Information center side control device 20 and a plurality of output control devices 25
and a character pattern conversion device 21 are connected to the common bus 27. Each output control device 25 is provided with an output device 26 such as a facsimile. The character pattern conversion device 21 includes a code analysis section 22 and a code/pattern conversion section 2.
3. It is composed of a bus control section 24.

The operation shown in FIG. 4 will be explained using the conventional bus usage state explanatory diagram of FIG. 5.

When transferring the character code output from the control device 20 to a desired output device 26, first, bus control of the common bus 27 for transferring the character code to the character pattern conversion device 21 is performed. The character code output from the control device 20 is then transferred to the code analysis aB 22 of the character pattern conversion device 21 via the common bus 27. The code analysis unit 22 analyzes what kind of character pattern the character code should be converted into. When this character pattern information is analyzed, it is converted into character turn data by the code/pattern converter 23.

In order to transfer the character pattern to a desired output device 26, bus control is performed by the bus control section 24.

Thereby, the character pattern is transferred via the common bus 27 to the output control device 25 corresponding to the desired output device 26.

Problems to be Solved by the Invention However, in the conventional character pattern transfer control method as described above, character code transfer and character pattern transfer are performed using the same common bus. At the time, character pattern transfer could not be performed, and there was a problem that the character pattern transfer efficiency decreased.

The present invention has been made in view of these points, and an object of the present invention is to provide a character pattern transfer control method that improves the efficiency of character pattern transfer.

Means to solve problems FIG. 1 is a block diagram of the principle of the present invention.

In a character pattern transfer control method in which a character code output from an information center 10 side is converted into a character pattern by a character pattern conversion means 11, and the character pattern is transferred to a desired output means 12 among a plurality of output means 12. ,
A character code transfer bus 13 is provided between the information center 10 and the character pattern conversion means 11, and a character pattern transfer common bus 14 is provided between the character pattern conversion means 11 and the output means 12.

Then, the character code is transferred by the character code transfer bus 13, and the character pattern is transferred by the character pattern transfer common bus 14.

According to the present invention, the character code transfer from the information center 10 to the character pattern conversion means 11 is carried out by the character code transfer bus 1.
3, and the character pattern transfer from the character pattern conversion means 11 to the output means 12 is performed on the character pattern transfer common bus 14, so each transfer is separated and the bus usage by character code transfer and character pattern transfer is This eliminates contention and improves character pattern transfer efficiency.

Embodiments The present invention will be explained in detail below based on embodiments shown in the drawings.

FIG. 2 shows a block diagram of an embodiment of the character pattern transfer control method according to the present invention.

Components that are the same as those of the conventional example shown in FIG. 4 are given the same reference numerals, and detailed explanation thereof will be omitted.

13 is a character code transfer bus, 14 is a character pattern transfer common bus, 20 is a control device, 21 is a character pattern conversion device composed of a code analysis section 22, a code/pattern conversion section 23, and a bus control section 24, and 25 is an output. control device, 2
6 is an output device.

Information center control device 20 and character pattern conversion device 21
A character code transfer bus 13 is provided between them, and a character pattern transfer common bus 14 is provided between the character pattern conversion device 21 and the output control device 1f25. Control device 20
The character code output from the character code transfer bus 13
is transferred to the character pattern conversion device 21. The character code is converted into a character pattern by the character pattern conversion device 21, and the character pattern is transferred to the output control device 25 corresponding to the desired output device 26 via the character pattern transfer common bus 14.

FIG. 3 shows an explanatory diagram of the bus usage state of the embodiment shown in FIG.

A plurality of output control devices 25 are connected to the character pattern transfer common bus 14, and the bus control unit 24 performs bus control when transferring character patterns. For example, when attempting to transfer a character pattern to the output control device 25 corresponding to the desired output device 26, if the character pattern transfer common bus 14 is being used for transfer to another output control device 25, When the transfer is completed, the data is transferred to the output control device 25 corresponding to the desired output device 26. No bus control is performed on the character code transfer bus 13, and character code transfer is performed sequentially.

Effects of the Invention Since the character pattern transfer control method of the present invention is configured as detailed above, character code transfer and character pattern transfer are separated, contention on the common bus is suppressed, and conversion efficiency into character patterns is improved. This has the effect that a desired character pattern can be obtained more quickly.
