CONSTITUTION:A deciding means 21 decides whether character code data received by a reception means is external character code data or not. If decision result information as the result of this decision indicates that received data are external character code data, a processing means 22 registers the external character code data and pattern data sent correspondingly to external character code data in a pattern data generating means. Since character code data are transmitted at a telegraphic message together with external character code data and corresponding pattern data in such a manner, it is registered in the pattern generating means and is used hereafter.

Description

Detailed Description of the Invention

 [Object of the Invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is connected to a data terminal that handles character code data (hereinafter, simply referred to as a character code)-for example, a word processor, a personal computer, etc .-- and is connected to another composite device via a line. The present invention relates to an improvement of a composite facsimile apparatus capable of receiving both a character code and image signal data (hereinafter, simply referred to as image signal) from a facsimile apparatus.

[0002]

2. Description of the Related Art In a compound facsimile apparatus of this type, a data terminal is an external character code data (character code data that does not meet a predetermined standard, such as character code data such as special symbols or marks). Yes, hereinafter, this is simply referred to as an external character)
Therefore, it is necessary to handle the above-mentioned external character code regardless of whether the compound facsimile apparatus serving as a transmitter or the compound facsimile apparatus serving as a receiver.

Therefore, if an external character code is arranged in advance in a closed system, the character code of a special character or the like has flexibility in the system and no particular problem occurs.

[0004]

However, the external character is originally registered and used when a new character, symbol, or the like needs to be used. When a new external character is created or changed on the data terminal side, the external character character code and the corresponding external character pattern data (hereinafter referred to simply as the external character pattern) are registered in the entire system. This had to be done for each complex facsimile machine, which was complicated.

Further, when an external character code is sent from a closed complex facsimile device outside the system, generally, even if there is an external character pattern corresponding to this external character code, it is appropriately associated. Not not. Therefore, the external character code is converted into an incorrect external character pattern. Further, if there is no external character pattern corresponding to the external character code, conversion to the external character pattern cannot be performed. In order to deal with this, there is a method of converting the external character code transmitted from the compound facsimile apparatus outside the closed system into a pattern such as all white (or all black) at a constant rate. However, in this case, the external character pattern is unknown and there is no point in transmitting the external character code.

The present invention has been made in view of the above-mentioned drawbacks of the conventional apparatus, and an object thereof is a composite apparatus capable of appropriately processing an external character code in both a closed system and an open system. A facsimile machine is provided. [Constitution of Invention]

Reference numeral 13 indicates an external character pattern memory. Gaiji pattern memory
An external character pattern transmitted from the partner facsimile machine of the external character pattern transferred from the data terminal via the interface 8 and input via the NCU 6 and the modem 7 is stored in the area 13. The external character pattern memory 13 stores a corresponding external character pattern with the external character character code as an address, and this memory is rewritable.

In such a complex facsimile apparatus, the control section 1 has a functional section as shown in FIG. 21 is
The determining means 21 determines whether or not each of the character codes received from a data terminal (not shown) or the other party's compound facsimile machine is an external character code. This determination means 21 is, for example, the upper n (n) of the input and binary encoded character code.
= 0,1, ...) bit is detected, and “1” is added to the n bits.
When is included, it is determined to be the external character code. Alternatively, when the arrangement is made such that the control code data is added to the external character code in advance, when this control code data is input, it is decoded and a predetermined output is performed. good. Alternatively, it has a memory table of the control code data or the external character code that becomes the minimum value when binary coded, and either matches the control code data or is a value equal to or greater than the stored external character code. It is also possible to determine that the character code is the external character code by detecting each character code.

Further, in this embodiment, the judging means 21 is
A memory table storing the IS character code,
The external character pattern memory 13 has a memory table in which the external character code corresponding to the external character pattern is stored, and the input character code is the JIS character code, or the external character pattern memory 13 has already stored the character code. The memory table is searched to determine whether each character is an external character code of the external character pattern.

Further, the processing means 22 has a transfer section 23, and the transfer section 23 sets the character code in the character code buffer 4 as a predetermined format in the modem 7.
To the character generator 10 or the external character pattern memory 13 for patterning the character code in the character code buffer 4 for transmitting the character code, or for patterning and sending to the recording unit 11. It has the necessary functions to do. Further, the processing means 22 includes an adding / deleting means 24 for adding / deleting control code data, and an external character pattern data transmission / reception detecting means 25 for detecting that the external character character code and the external character pattern are collectively transmitted / received in a required group. And an effective period storage means 26 for storing the effective period of the external character pattern currently stored in the external character pattern memory.

The adding / deleting means 24 adds the control code data in advance of the external character code when the external data character code and the external character pattern corresponding thereto are included in the data to be transmitted / received. Then, the control code data is deleted when it is added.

External character pattern data transmission / reception detection means 25
Is control information for facsimile transmission (for example, NSF, N
Based on the SS signal), it is detected that only a required set of external character code and external character pattern are transmitted / received together.
That is, the control information is analyzed to detect that a required set of external character code and external character pattern are collectively transmitted and received, for example, depending on whether the predetermined flag is "1" or "0". The valid period storage means 26 stores, for example, the ID of the partner compound facsimile machine to be transmitted (or transmitted). Then, as long as the other party does not change, the external character pattern in the external character pattern memory 13 is validated. Further, it is also possible to store in the effective period storage means 26 such that the external character pattern is valid up to a page unit and the external character pattern in the external character pattern memory 13 is effective on that day. .

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

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

Next, when the panel section 12 is operated and the character code of the electronic message is transmitted from the data terminal through the interface 8, the control section 1 displays the character code as shown in step 101 of the flowchart of FIG. The character code is input, and in step 102, the determination means 21 determines whether or not the character code is an external character code.

[0019]

[Outer 1]

This operation is performed by the judging means 21 as described above.
This is performed by searching the memory table in which the IS character code is stored.

"3A62" for "goods", "3741" for "shapes", "233" for "3"
"330" and "0" are displayed as "2330", and "10,000" are displayed as "4B7D" in hexadecimal according to the JIS standard. When this character code is input, the control unit 1 proceeds from step 103 to step 104. After confirming that the character code buffer 4 is empty in step 104, the transfer unit 23 writes the character code in 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.

[0022]

[Outside 2]

This determination is performed by the determining means 21 by searching the memory table of the external character code of the external character pattern stored in the above-mentioned external character pattern memory 13.

[0024]

[Outside 3]

Thereafter, the external character pattern is transferred to the image signal buffer 5 by the operations of the above-mentioned steps 104 to 106.
When the result in steps 103 and 107 is NO, the controller 1 sounds an alarm and waits for operator intervention.

When all the character codes are processed in this way, the control unit 1 controls the NCU 6 to send the data to the called compound facsimile machine of the other party by the transmission control procedure of 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 NSS signal causes
The transmitter informs the receiver that the pattern (image signal) and the character code are mixed to perform the facsimile transmission.

Following this, the transmitter sends a TCF signal, training is performed, and when preparation for reception is completed, a CFR signal is sent from the receiver. Here, the transmitter transmits the mixed data of the character code and the pattern (image signal).

[0029]

[Outside 4]

A line 00FF00 b line 0300D0 c line 0D7FB0 :: :: ::: w line 03D1D0 x line 00FF00, which is transmitted. Furthermore, "3", "0",
Character code "233" for each of "0" and "10,000"
3 ”,“ 2330 ”,“ 2330 ”,“ 4B7D ”are transmitted, and the EOP signal indicating the end of transmission is transmitted to the receiver. Therefore, from the receiver, confirm that the reception was successful.
When returned by the CF signal, the transmitter sends a DCN signal to disconnect the line.

When the compound facsimile apparatus of the embodiment becomes a receiver, it operates as shown in the flowchart of FIG. First, in the control unit 1 which has received the character code via the NCU 6 and the modem 7 in step 201, the judging means 21 judges whether or not it is the external character code as shown in step 202.

[0032]

[Outside 5]

In step 203, the judging means 21 judges whether or not it is the JIS code by the memory table of its own, and if YES, the above character code and judgment result information indicating that this character code is not the external character code. Is output. These are given to the transfer unit 23 via the adding / deleting means 24, and the transfer unit 23 determines in step 204
At, the character code is sent to the character generator 10 to read the corresponding pattern. Further, the process proceeds to step 205, where it is confirmed that the image signal buffer 5 is empty, and the process proceeds to step 206 to write the pattern in the image signal buffer 5. Further, the control unit 1 returns to step 201 and continues the operation until it confirms in step 207 that the reception of all data is completed.

[0034]

[Outside 6]

Further, in step 209, the transfer unit 23 receives the determination result information, the external character code, and the external character pattern, and stores the external character pattern in the external character pattern memory 13 at an address corresponding to the external character character code. Furthermore, for the external character pattern, as described above, step 20
5 The image is stored in the image signal buffer 5 in accordance with the flowcharts thereafter.

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

In this way, once the external character code and its pattern are received, the effective period storage means
26 receives the NSF signal shown in FIG. 4 and stores the ID of the transmitter. After that, the control unit 1 performs the operation as shown in FIG. 8 in place of the one-dot chain line in the flowchart of FIG. That is, in step 301, 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 or not the ID in the effective period storage means 26 is the same as the last time, and if YES, in step 303 the corresponding external character pattern is read from the external character pattern memory 13. Incidentally, step 30
If the corresponding external character pattern is not stored in the external character pattern memory 13 in 1 or it is determined in step 302 that the external character pattern is an external character character code transmitted by the compound facsimile machine with a different ID and is not valid. , Both sound an alarm and wait for operator intervention. However, in such a case, the transfer unit 23
Receives the above result information,
A predetermined pattern such as an all-white pattern (or an all-black pattern) may be read from 11 and stored in the image signal buffer 5 in step 205.

FIG. 9 shows a transmission control procedure in the case where a necessary external character code and a corresponding external character pattern are sent in a required group in advance. Here, the transmitter is shown in FIG.
The external character code and the external character pattern are transmitted one after another in accordance with the flowchart of FIG. In addition, when the information indicating that the data is to be collectively transmitted is previously transmitted by the NSS signal, the external character pattern data transmission / reception detection means of the receiver.
25 detects this and notifies the transfer unit 23. Then, the transfer unit 23 suspends the determining unit 21 and the adding / deleting unit 24 so that the external character code and the external character pattern are simply passed. The external character code is the first 2 bytes, and the external character pattern is 3 x 24 bytes, so (2 bytes) + (3 x 24 bytes) is defined as one unit.
Synchronously, the transfer unit 23 stores the external character pattern in an address corresponding to the external character code in the external character pattern memory 13.

When the transmission is completed for all the external character code and external character pattern, the transmitter transmits the character code of the electronic message. Although this character code includes the external character code, step 109 is omitted in the flowchart of FIG. 3 and the external character pattern is not sent. Also, step 108 may be omitted and control code data may not be added.

In the receiver, the character code thus transmitted is patterned according to the flow charts of FIGS. 7 and 8, and is sent to the recording section 11 for recording operation in the recording section 11. At this time, the transfer unit 23 uses the effective period storage means 26.
The external character code is patterned by referring to.

By doing so, it is possible to ensure the generation of a proper external character pattern even if the external character code differs between the terminals.

[0042]

As described above, according to the present invention,
The external facsimile character code data and the corresponding pattern data are sent together with the character code data from the other party's compound facsimile machine, so that they are registered in the pattern generating means and are used thereafter. Therefore, accurate recording is guaranteed without registration in advance. To be done. For this reason, it is convenient because no special external character registration work is required for each device in the system.
