Abstract

PURPOSE:To prevent a circuit from being grasped at an unnecessary time and to perform communication control by disconnecting the circuit temporarily after the reception end of character codes is detected, and calling an opponent complex facsimile equipment on the basis of communication control information and sending out necessary information once the completion of recording operation is detected. CONSTITUTION:When all character codes in a character code buffer 2 are recorded as picture data at a recording part 5, the 1st detecting means 11 detects the completion of the recording operation. Consequently, a control part 1 reads the necessary communication control information out of a memory 2' in order to call an origination side which transmits the character codes, and sends out dial number data. When the origination side answers to it and a circuit connection is made, the origination side sends a nonstandard function signal or standard function signal and a called side sends out a signal responding to it. For example, this signal includes information indicating correct reception and recording, information indicating that the reception is not performed correctly, or information indicating that the absence of recording paper or jams.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a transmission system for transmitting character codes by a complex facsimile device.

[Technical background of the invention and its problems]

With a conventional facsimile machine, 11! , when sending out im data, a dummy signal is added to the artist data sent from the sending facsimile device, and the time required for the receiving facsimile device to perform the recording operation (hereinafter referred to as recording output time, and sending time) was made to match on a per-page basis or on a per-multiple-line basis.

It is impossible to match the recording output time and the sending time on a per-page basis with a complex facsimile machine capable of transmitting character codes. That is, J
The transmission of the character code corresponding to the original number 4 in the IS A column usually ends in 2 to 3 seconds, but if the recording operation of the reception 111 + facsimile device is slow, the transmission of the character code corresponding to the original number 4 in column A is completed, but if the recording operation of the reception 111 + facsimile device is slow, the character code of the first page or several pages may be sent. Even if there is a code memory, transmission must be stopped every time the character code memory becomes full, and in terms of total time, it takes about the same amount of time as when transmitting image data.

Unfortunately, if the line is disconnected after sending several pages of character code, the receiving 4M (lj:l facsimile machine will run out of recording paper, the recording paper seam, etc.), and the receiving (, T data will not be processed. If the transmission fails, the superstitious facsimile cannot request retransmission, or it may be abnormal. The purpose of this system is to provide a transmission system using a complex facsimile machine that can prevent lines from being seized at unnecessary times and can also manage communications.

[Summary of the invention]

Therefore, in the present invention, the compound facsimile device includes a character code buffer for storing the character codes of multiple pages of documents, a memory for storing communication control information sent from the other party's compound facsimile device, and a character code buffer for storing the communication control information sent from the other party's compound facsimile device. comprising a first detection means for detecting the end of the note t'l-m work corresponding to the character code, a second detection means for detecting the end of reception of the character code, and a control means,
After detecting the end of character code reception, the line is disconnected, and once the end of the recording operation is detected, a call is made to the other party's compound facsimile machine based on the communication control information above, and the necessary information is sent. I made it.

[Embodiments of the invention]

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

FIG. 1 is a block diagram of a composite facsimile apparatus that implements the transmission method of the present invention. In the figure, numeral 1 denotes a control section, which controls each section in the figure. 2 is a character code buffer, which is used to store the received galactor code tray. Reference numeral 2' denotes a memory, and this memory 2' stores not only zolograms that are accepted by the control section 1, but also data used by the control section 1.

3 is a modem, 4 is a network control unit that starts and restores the switching network, 5
Reference numeral 1 indicates a recording section, 6 a panel section for performing various inputs, and 7 a character code/image data conversion section.

In the composite facsimile machine configured in this way, the sending facsimile machine outputs a character code via the network control unit 4, and the receiving facsimile machine receives and receives the character code via the network control unit 4. .

The control unit 1 is functionally shown in FIG. 2. υ
;j also, 11 is the first detection means for detecting the end of outputting the copy corresponding to the character code taken;
Reference numeral 12 denotes a second detection means for detecting the end of reception of the character code. Other functions of the control section 1 include a function of controlling each section in FIG. 1 and a communication control function.

Transmission by the composite facsimile apparatus configured as described above will be explained with reference to FIG.

In this example, it is assumed that the character code is sent from the original calling party (the sending compound facsimile machine). The line is now seized and the called party (receiving complex facsimile machine) sends an N5F (indicating non-standard function) signal or a DIS (
A signal (indicating a standard function) is sent out. In response, the calling side sends N5S (sending command in response to NSF signal) 1g.
A signal or a DO8 (send command in response to a DIS signal) signal is sent. For example, the ID number of the calling party in the NSS signal,
Contains communication control information such as telephone number and transmission serial number.

This communication control information is stored in the memory 2' by the control section 1. Furthermore, the calling side sends out a TCP (training check) signal, and in response to this, the called side sends out a CFR (reception readiness confirmation) signal. Therefore, the calling side sends the character code in an amount that is less than or equal to the data amount corresponding to the capacity of the called side's character code buffer (this capacity can be known from, for example, an NSF signal). Then, the second detection means 12 on the called side receives an EOP (indicating that there is no transportation) from the calling side.
When it is detected that the signal has been sent, the control unit 1 on the called side sends an MCF-WA signal, which is a signal to notify the final result after the recording operation, instead of the MCF (message confirmation) signal.
Sends IT signals. Then, the calling party receives the DCN (
Outputs a signal commanding disconnection of the line, and the reminiscence is disconnected.

On the called side, when the character code for one page of the original is stored in the character code buffer 2, the controller 1
reads this character code (il-read and sends it to the character code/image data conversion section 7. As a result, the character code is converted into image data, and this image data is sent to the recording section 5 by the control section). In the recording section 5, the receiver performs predetermined printing on the recording paper based on the image data taken.In this way, all the character codes in the character code buffer 2 are converted into image data, and when the recording section 5 finishes recording, , the first detection means 11 shown in FIG. 2 detects the end of the recording operation.Thereby, the control unit 1 transmits the communication control information necessary to call the calling party that has transmitted the character code. memory 2
' and sends out the dial number data as shown in FIG.

When the calling side responds to this and a line connection is established, an NSF signal or D/S signal is sent from the calling side, and an NSS signal or DC8 signal is sent from the called side. . For example, information indicating that the NSS signal was correctly received and recorded, information indicating that it was not correctly received, or information indicating that the recording paper is out or the recording paper is jammed is inserted into the NSS signal. be done. Therefore, this NSS
By receiving the signal, the calling side that sent the character code receives, for example, information that the character code has been correctly received and recorded, outputs a DCN signal, and disconnects the line. Also,
When the calling side receives information indicating that reception was not possible correctly, that the recording paper is out, or that the recording paper is jammed, the control unit 1 of the calling side stores, for example, the character code corresponding to this information in the memory 2. ', and sends it to the character code/image data conversion section 7. l! The data of the 1st team is sent to the recording unit 5, the recording operation is performed, and the operator waits for intervention.

Alternatively, if the control unit 1 has a retransmission function, all character codes of the necessary pages may be retransmitted.

[Effects of the Invention] As explained above, according to the present invention, the 5 lines are always disconnected after the character code is sent and while the receiving compound facsimile machine is in the recording operation. This eliminates the inconvenience of having your line tied up at times. In addition, since the necessary information is sent from the receiving compound facsimile device to the sending compound facsimile device that sends the character code, it is possible to manage communication, and if the character code is not received correctly, retransmission can be performed. It is extremely convenient because it allows you to perform various types of processing.
