Abstract

PURPOSE:To process suitably the external characters both in the open or close systems, by installing the means for judging whether it is the external character code or not, and the external character pattern memory. CONSTITUTION:When the telegram character code is sent from the data terminal, a deciding means 21 decides whether the character code is an external character code or not in the control part. When the character code is the external character code, it is decided whether or not there is the pattern corresponding to the character code in the external character pattern memory. When there is a pattern corresponding to said code, the character code is set to addition and deletion means 24 together with the decided result information. At the means 24, the control code is added to the character code and is sent to a transfer part 23 together with the decided result information. The transfer part 23 sends the character code onto the bath based on the decided result information, accesses the external pattern memory and reads out the corresponding external character pattern.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a device that is connected to a data terminal that handles character code data (hereinafter simply referred to as a character code), such as a word processor, a personal computer, etc., and that processes character code data via a line. The present invention relates to an improvement in a compound facsimile device capable of transmitting and receiving both codes and image signal data (hereinafter simply referred to as image signals).

[Technical background of the invention]

In this type of compound facsimile device, the data terminal is configured to transmit external character code data (character code data that does not meet the specified standards, such as character code data such as special symbols or marks, as described below).
These are simply called external characters).
Whether it is a compound facsimile device that acts as a transmitter or a compound facsimile device that acts as a receiver, it is necessary to handle the above-mentioned external character code.

Therefore, if external character codes are agreed upon in advance within a closed system, character codes such as special characters will be compatible within the system and no particular problem will occur.

[Problems with background technology]

However, external characters are originally registered and used when it becomes necessary to use new characters, symbols, etc. When a new custom character is created or changed on the data terminal side, the registration of the custom character code and the corresponding custom character pattern data (hereinafter simply referred to as the custom character pattern) will be performed for the entire system. It had to be done and was complicated.

Furthermore, when a private character code is sent from a complex facsimile machine outside the closed system, even if there is a private character pattern corresponding to the private character code, it is generally not properly associated with the character code. For this reason,
The above-mentioned private character character code is converted to an incorrect private character pattern. Further, if there is no private character pattern corresponding to the private character code, conversion to a private character pattern cannot be performed. To deal with this, there is a method of converting the private character code sent from a compound facsimile machine outside the closed system into a pattern such as all white (or all black). However, in this case, the private character pattern is unknown, and there is no point in transmitting the private character code.

[Purpose of the invention]

The present invention was made in view of the drawbacks of the conventional devices as described above, and its purpose is to
To provide a compound facsimile device that can appropriately process external character codes even in an open system.

[Summary of the invention]

Therefore, in the present invention, there is provided a determination means for determining whether each of the input character codes is a non-standard character code, a non-standard character pattern memory for storing a non-standard character pattern corresponding to the non-standard character code; A compound facsimile apparatus is configured, comprising processing means for receiving the determination result information and processing the input character code by accessing the private character pattern memory when the information indicates that the information is a private character. .

[Embodiments of the invention]

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

FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, 1 indicates a control section. This control section 1 is, for example, a microprocessor, and controls each section via a bus 2 to compress and expand image signals. A main memory 3 is connected to the bus 2, and the main memory 3 stores control programs and various data used by the control section 1. 4 is a character code buffer,
This character code buffer 4 contains a character code transferred from a data terminal (not shown) via an interface 8 (described later), or a character code transmitted from a destination compound facsimile device (not shown) and transmitted from a network control unit 6 or a modem 7 (described later).
The character code input via the controller 1 is stored under the control of the controller 1. Reference numeral 5 indicates an image signal buffer, and this image signal buffer 5 contains a pattern (image signal) corresponding to a character code in the character code buffer 4, which has been converted by a character generator 10 or an external character pattern memory 13, which will be described later. Alternatively, an image signal corresponding to a document read by a reading unit 9 (to be described later), or an image signal transmitted from a facsimile machine of the other party and input via a network control unit 6 and a modem 7 are transmitted through the bus 2, respectively. stored via.

6 indicates a network control unit (hereinafter referred to as NCU);
The CU 6 is controlled by the control unit 1 via the bus 2, and
Makes and restores calls to the switched network. 7 is a modem, which modulates the image signal or character code input via bus 2 and outputs it to NCU 6, demodulates the image signal or character code input via NCU 6, and outputs it to bus 2. . An interface 8 is connected to a data terminal (not shown), receives the character code transferred from the data terminal, and outputs it to the bus 2. 10 is a character generator, which stores patterns corresponding to character codes of the JIS standard.

The character generator 10 receives the character code read out from the character code buffer 4 by the control unit 1, converts it into a corresponding pattern, and outputs it.

If the output pattern is for transmission, it is compressed by the control unit 1 and stored in both signal buffers 5, and if it is for recording, it is stored as is in the image signal buffer.

11 is a recording section. The recording unit 11 receives the compressed image signal and sends it from the image signal buffer 5 to the control unit 1.
An image signal read out and expanded by an image signal, or an image signal corresponding to a character code in the character code buffer 4 that is transmitted from a data terminal (not shown) or a multifunction facsimile device of the other party and patterned by the character generator 10, or an external character. The pattern memory 13 receives an image signal corresponding to a non-standard character code in a patterned character code, and performs a recording operation. Reference numeral 12 denotes a panel section through which the operator can input various commands and data such as starting transmission.

The input commands and the like are taken into the control section 1 via the bus 2, and the control section 1 performs processing based on them. Further, the control section 1 sends a command to the panel section 12 via the bus 2 in order to turn on or off a lamp (not shown) of the panel section 12. 13 indicates a private character pattern memory. The external character pattern memory 13 stores the external character pattern transferred from the data terminal via the interface 8 from the other party's compound facsimile machine, and the NCU 6. A custom character pattern input via the modem 7 is stored. In the private character pattern memory 13, corresponding private character patterns are stored using private character character codes as addresses, and this memory is rewritable.

In such a compound facsimile device, the control section 1
has functional parts as shown in FIG. Reference numeral 21 indicates a determining means, and the determining means 21 determines whether each character code received from a data terminal (not shown) or a multifunction facsimile machine of the other party is a non-standard character code. This determining means 21 is configured to, for example, select the top n (n=0,
1, ---) bits are detected, and when the n bits include "1", it is determined that it is a non-standard character code. Alternatively, if you have made an agreement to add control code data to the private character code in advance, when this control code data is input, it can be decoded and a specified output is performed. good.

Alternatively, it has a memory table of control code data or a non-standard character code that has the minimum value when binary encoded, and the value matches the control code data or is greater than or equal to the stored non-standard character code. It may be determined that the character code is a non-standard character code by detecting whether the character code is a character code or not.

Furthermore, in this embodiment, the determining means 21 has a memory table in which JIS character codes are stored and a memory table in which non-standard character codes corresponding to the non-standard character patterns stored in the non-standard character pattern memory 13 are stored. The memory table is searched to determine whether the input character code is a JIS character code or a non-character character code of a non-character pattern already stored in the non-character pattern memory 13.

Further, within the processing means 22, there is a transfer unit 23, which has a function of transferring the character code in the character code buffer 4 to the modem 7 in a predetermined format. , the character generator 10, or the function of transferring the character code to the external character pattern memory 13 and creating a pattern, etc., which are necessary for transmitting the character code or patterning it and sending it to the recording unit 11. The processing means 22 also includes an addition/deletion means 24 for adding and deleting control code data, and a character pattern data transmission/reception detection means 25 for detecting that a necessary set of a character code and a character pattern are transmitted and received together. and a valid period storage means 26 for storing the valid period of the private character pattern currently stored in the private character pattern memory.

When it is indicated that the data to be transmitted and received includes a non-standard character code and a corresponding non-standard character pattern, the addition/deletion means 24 adds control code data in advance of the non-standard character code and transmits the data. Or, if control code data is added, it is deleted.

The external character pattern data transmission/reception detection means 25 also detects facsimile transmission control information (for example, NSF).

(NSS signal), it is detected that necessary sets of private character character codes and private character patterns are sent and received at once. That is, the above control information is analyzed and, for example, depending on whether a predetermined flag is "1" or "0", it is detected that the necessary set of private character character codes and private character patterns are sent and received at once. The validity period storage means stores, for example, the ID of the other party's multifunction facsimile device to which the data is to be sent (or to which the data has been sent). Then, as long as the other party does not change, the external character pattern in the external character pattern memory 13 is made valid. The validity period storage means 26 can also store information such as how many pages the custom character pattern is valid for, or that the custom character pattern in the custom character pattern memory 13 is valid on that day. .

The operation when the composite facsimile apparatus configured as described above functions as a transmitter will be explained.

It is assumed that the external character pattern and its external character character code are transferred in advance from a data terminal (not shown) via the interface 8, and the necessary external character pattern is already stored in the external character pattern memory 13.

Next, the panel section 12 is operated and the data terminal is operated.

When the character code of the message is sent via the interface 8, the control unit 1 inputs the character code as shown in step 101 of the flowchart of FIG. Determine whether or not is a private character code. Here, it is assumed that the character code "[Treasury accumulation (excellent) 3,000,000 yen]" is input. These “assets of 3 million yen”
Among the character codes, the character code for "(excellent)" is a non-standard character code, and the character codes for other characters are JIS character codes.

The determining means 21 determines that the character code of the characters other than "(excellent)" is a JIS character code and is not a non-standard character code, so the determination means 21 determines NO in step 102 for the character code of the characters other than "(excellent)". , Next, in step 103, it is checked whether or not it is a JIS character code. In this operation, as described above, the determination means 21
This is done by searching the memory table in which the character code is stored.

“3A62” for “goods” and “3A62” for “shape”
741”, “2333” for “3”.

“2330” for “O” and “4” for “10,000”
B7D" is displayed in hex according to the JIS standard. If this character code is input, the control section 1 proceeds from step 103 to step 104. After confirming that the character code buffer 4 is empty in step 104, the transfer unit writes the character code to the character code buffer 4 in step 105. The transfer unit 23 repeats the operations between step 106 and step 101 until it detects a code indicating the end of data in the input character code.

Now, in step 102, the determining means 21 is "(excellent)"
'' character code ``7442'' is input and it is determined that it is a non-standard character code. Then, YE
The process branches to S and proceeds to step 107, where it is determined whether or not there is a pattern corresponding to the "(excellent)" character code in the external character pattern memory 13. This determination is made by the determination means 21 searching the memory table of the private character character codes of the private character patterns stored in the private character pattern memory 13 described above. If YES here, the character code "(excellent)" is sent to the separate addition/deletion means together with the determination result information indicating that it is a non-standard character code. Therefore, in step 108,
The addition/deletion means 24 adds the control code data "7441" in advance to the character code "(excellent)" and sends it to the transfer section 23 together with the determination result information. In step 109, the transfer unit sends the character code "(excellent)" onto the bus 2 based on the determination result information, accesses the private character pattern memory 13, and reads out the corresponding private character pattern. Thereafter, the external character pattern is transferred to the image signal buffer 5 by the operations in steps 104 to 106 described above. Note that if NO is determined in steps 103 and 107, the control unit 1
sounds an alarm and waits for operator intervention.

After all character codes have been processed in this way, the control section 1 controls the NCU 6 to transmit data to the called party's multifunction facsimile machine according to the transmission control procedure shown in FIG.

That is, the transmitter already knows from the NSF signal that the receiver can receive both the image signal and the character code, and the transmitter uses the NSS signal to mix the pattern (image signal) and character code. The receiver is notified that the facsimile transmission will be performed using

Following this, a TCF signal is sent out from the transmitter, training is performed, and when preparation for reception is completed, a CFR signal is sent out from the receiver. Here, data in which a character code and a pattern (image signal) are mixed is sent out from the transmitter. As mentioned above, “asset accumulation (excellent) 3 million yen”
Since the character code and external character pattern of are stored in the character code buffer 4 and the image signal buffer 5, the control unit 1 reads each of "goods" and "shape" from these buffers, as shown in FIG. Character code "3A"
After sending out "62" and "3741", the control code data "7441" of the private character and the private character character code "7442" of "(excellent)" are transmitted. Next, the "(excellent)" external character pattern is sent out as a 3×24 byte signal. This external character pattern is composed of 24 bits x 24 bits as shown in FIG.

The pattern of "(Excellent)" used here is as shown in the same figure, so if it is displayed in hex format, it will be as follows: Line a 00FF00 Line B 0300D0 Line C 0D7FB0 ・ ・ ・ ・ ・ ・ ・ ・ ・ Row W 03D1D0 The xth line 00FF00 is transmitted. Furthermore, "3", "0", "0"
”, “10,000” character codes “2333”, “
2330", "2330", and "4B7D" are sent,
An EOP signal indicating the end of transmission is sent to the receiver. Therefore, when the receiver sends back an MCF signal indicating that the reception was successful, the transmitter sends out a DCN signal and disconnects the line.

When the composite facsimile apparatus of this embodiment becomes a receiver, it operates as shown in the flowchart of FIG.

First, in step 201, the control section 1 receives the character code via the NCU 6 and the modem 7, and the determination means 21
As shown in step 202, it is determined whether or not it is a non-standard character code. Here, character codes other than "(Excellent)" in the character code for "Property 3 million" above are JIS character codes, so NO.
The process branches to step 203 and proceeds to step 203. In step 203, the determiner means 21 determines whether or not it is a JIS code using its own memory table, and if YES, outputs the character code and determination result information indicating that this character code is not a private character character code. do. These are given to the transfer unit 23 via the addition/deletion means 24, and in step 204, the transfer unit 23 sends the character code to the character generator 10 and reads out the corresponding pattern. Furthermore, the process proceeds to step 205, where it is confirmed that both signal buffers 5 are empty, and the process proceeds to step 206, where a pattern is written into the image signal buffer 5. Furthermore, the control unit 1 returns to step 201 until it confirms in step 207 that reception of all data has been completed,
Continue working.

In addition, in the case of control code data, private character character code, and private character pattern for "(excellent)", step 2
02 is YES, and in step 208, the addition/
The deletion means 24 deletes the control code data "7441". Furthermore, in step 209, the transfer unit 23 receives the determination result information, the private character character code, and the private character pattern, and stores the private character pattern at the address corresponding to the private character character code in the private character pattern memory 13. Furthermore, regarding the external character pattern, as mentioned above, step 2
According to the flowchart from 05 onwards, the image signal buffer 5
Store it in

In this way, after receiving all the data (or during reception), the control section 1 sequentially sends the image signals accumulated in the image signal buffer 5 to the recording section 11. Recording section 11
receives this and performs a recording operation.

In this way, once the private character code and its pattern are received, the validity period storage means 26 stores the fourth
Upon receiving the NSF signal shown in the figure, the ID of the transmitter is stored. From now on, the control unit 1 performs the operations shown in FIG. 8 instead of the portion indicated by the dashed-dotted line in the flowchart of FIG. 7.

That is, in step 301, in the external character pattern memory 13,
The determining means 21 determines whether or not there is a corresponding external character pattern.

Further, in step 302, the transfer unit 23 determines whether the ID of the valid period storage means station 26 is the same as the previous ID, and if YES, the corresponding external character pattern is read out from the external character pattern memory 13 in step 303. Note that in step 301, if the applicable custom character pattern is not stored in the custom character pattern memory 13, or in step 302, it is determined that the custom character code is not valid because it was sent by a compound facsimile machine with a different ID. In either case, sound an alarm and wait for operator intervention. However, in such cases,
The transfer unit n may receive the above result information, read out a predetermined pattern such as an all-white pattern (or an all-black pattern) from the character generator 11, and store this in the image signal buffer 5 in step 205. good.

FIG. 9 shows a transmission control procedure for transmitting necessary sets of external character character codes and corresponding external character patterns that are required in advance. Here, the transmitter sequentially transmits the private character code and its private character pattern according to the flowchart of FIG. Also, in advance, NS
When the S signal is used to send out information indicating that the data will be transmitted all at once, the external character pattern data transmission/reception detection means 25 of the receiver will:
This is detected and notified to the transfer unit 23. Then, the transfer unit 23 stops the determining means 21 and the addition/deletion means 24, and simply passes the private character character code and the private character pattern. The private character character code is the first 2 bytes, and the private character pattern is 3×24 bytes, so the transfer unit 23 synchronizes the private character pattern with (2 bytes) + (3×24 bytes) as one unit. The pattern is stored in the address corresponding to the external character code in the external character pattern memory 13.

When the transmission of all the private character codes and private character patterns is completed, the transmitter transmits the character code of the message. Although this character code includes a non-standard character code, step 109 in the flowchart of FIG. 3 is omitted so that the non-standard character pattern is not sent. Further, step 10B may also be omitted and control code data may not be added.

The character code transmitted in this manner is patterned in the receiver according to the flowcharts of FIGS. 7 and 8, and sent to the recording section 11, where the recording section 11 performs a recording operation. At this time, the transfer unit 23 stores the validity period storage means 26.
Refer to , and pattern the external character code.

In this way, even if the non-standard character codes differ between terminals, it is possible to ensure the generation of appropriate non-standard character patterns.

〔Effect of the invention〕

As explained above, according to the present invention, the private character character code and the private character pattern used in the transmitter are transmitted to the receiver, a message is sent, and recording is performed based on this. You can record. Therefore, in a closed system, it is easy to change or add a character code, and even in an open system, messages can be transmitted using the character code without any inconvenience. Furthermore, the once sent private character character code and private character pattern are subject to predetermined conditions (for example,
If it is treated as valid for each page, for each series of transmissions, and for each terminal, a lot of transmission time is required at the beginning, but after that, only the character code is required, which reduces transmission time and improves efficiency. Can be transmitted well. Furthermore, even in this case, it is possible to change or add a custom character pattern to the custom character code when necessary, which is extremely convenient.
