Abstract

PURPOSE:To improve the transmission efficiency of facsimile communication messages by having a character code system original to a facsimile replay system in addition to a character code system prescribed by the JIS standard and therefore increasing the number of applicable characters via the 1-byte character code. CONSTITUTION:A host computer 1 produces a facsimile communication message with character codes and gives an instruction to a facsimile response equipment 2 via a communication circuit 12 to deliver the character codes to a facsimile terminal. Here the information which gives index to a conversion table 23 or 24 is added to the facsimile communication message and a character code contains a single byte. The equipment 2 analyzes the facsimile message supplied from the computer 1 through a control part 21 and retrieves the corresponding character code dot pattern out of a character code dot pattern memory 22 via the table 23 as long as the character code is defined by the JIS standard. While the table 24 is used for the retrieval of the character code corresponding to the facsimile system. Thus the original picture signals for a page of facsimile are produced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a facsimile response device that converts a character code into a facsimile signal and outputs the signal to a facsimile terminal.

The facsimile response device receives character code information from a host computer or the like, converts the character code into a facsimile signal, and outputs the signal to a facsimile terminal. Therefore, the facsimile answering device must store character dot patterns corresponding to character codes. Examples of this type of character dot pattern include Japanese Industrial Standards (JIS).
), which correspond to the character codes specified in the information processing character code table (JIS C6220, JIS G 6226, etc.).

According to such a character code table, the maximum number of 1-byte character codes is 256 characters, so most character codes are 2-byte characters. If this is done between the facsimile answering device and the facsimile answering device, there is a problem in that the transmission efficiency deteriorates as shown below.

(1) Compared to 1 byte and 71 characters, 2 bytes/
A single character doubles the transmission time.

(2) When character code information for one page of the facsimile screen is divided into multiple blocks and transmitted to the host computer using the facsimile response device button, the number of times the data is transmitted increases.

Incidentally, as this type of device, one described in Japanese Patent Laid-Open No. 165558/1983 is known.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile response device that has high transmission efficiency with a host computer.

[Summary of the Invention] In order to achieve the above object, the present invention has a system-specific character encoding system other than the next character encoding format specified by the JIS standard. Used for each system to increase the number of characters that can be used with a 1-byte character code.

[Embodiments of the invention] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The figure is a block diagram of a facsimile answering device. connected to a host computer 1 via a communication line 12;
A facsimile answering device 2 connected to a facsimile terminal (not shown) via a telephone line +1li13 has a control unit 2.
1 and a character code dot pattern memory 22, and conversion tables 23 and 24 inside the control section 21.

The character code dot pattern memory 22 contains JIS C6
220 and character dot patterns based on the character code table for information processing specified by TIS C6226 are stored.

The conversion table 23 is a table that associates one-byte character codes among the character codes specified by JIS with the seven addresses in the character code dot pattern memory 22 in which the character code dot patterns are stored. .

The conversion table 24 shows character codes and their characters when 256 frequently used character codes are replaced with character codes in a syllabite structure based on the system's own character coding system, out of character codes in a 2-byte structure according to the JIS standard. Character code dot pattern memory 2 in which code dot patterns are stored
This is a table that associates addresses within 2.

The host combination, E-1, creates a facsimile message using a character code, and instructs the facsimile response device 2 to output the character code to the end of the facsimile machine 1 via the communication line 11112. Here, information for indexing the conversion table 25 or 24 is added to the facsimile message,
The character code is composed of 1 pie j. In other words, in the case of this embodiment, for each message or for each character code within the message, check whether the character code is of the JIS standard (whether it is a character code for which the conversion table 23 should be used) Or, since the character code has information as to whether it is unique to the system (whether the character code should use the conversion table 24), the structure of the character code is 1 byte.

The facsimile response device 2 analyzes the facsimile message input from the host computer 1 with the control unit 21,
If it is a character code based on the JIS standard, the corresponding character code dot pattern is searched from the memory 22 in the conversion table 23, and if it is a character code unique to the system, it is searched in the conversion table 24.
The corresponding character code dot pattern is retrieved from the memory 22 and the entire original image signal for one facsimile page is generated. This original image signal is code-converted into a format compatible with the facsimile terminal button and sent to the telephone line 1m3.

In this way, according to this embodiment, since it has a character code conversion table based on the JIS standard and a character code conversion table unique to the system, the casing and character code dot pattern memory can be used to reduce the software load. Since it can be shared, memory can be saved.

If it is desired to further increase the number of character codes based on the system's unique character code system, it is sufficient to simply increase the number of conversion tables and provide information for indexing the increased conversion tables to the facsimile message.

〔Effect of the invention〕

According to the present invention, there is an effect of improving the transmission efficiency of a message in which a 1-byte character code can be used in two or three times, and by a factor ξ.
