Description

The present invention relates to an image transmission device, and more particularly to an image communication device that responds to a signal intended for telephone reservation from a partner device. <Prior Art> A facsimile device having a conventional image memory and capable of memory transmission does not send all image signals at the time of memory transmission, but is a signal intended for telephone reservation (hereinafter, telephone reservation signal). However, when it is sent from the other receiver, there are roughly two types of methods. The first method is to immediately accept it and stop the memory transmission.
The second method is to
It is a method of not accepting a telephone reservation signal from the receiver of the other party. In the first method, when all the image signals have not been transmitted at the time of memory transmission, the telephone reservation signal from the receiver of the other party is received, and when the operator raises or lowers the telephone receiver of the telephone, the facsimile machine In the standby state, the handset is picked up and becomes exactly the same as the state in which a telephone call is made. If the call ends here and the sender wants to send memory again, Faximili will respond according to the open / closed status of the line.
Determine the operation such as sending / not sending the selection signal, and
The transmission procedure for communication is retransmitted from the beginning, including the image signal already transmitted repeatedly. So, for example, when sending 100 sheets of memory to the memory, after sending the 99th sheet, make a call by telephone reservation, and then again
If the sender wants to send to the memory, it is necessary to repeat the transmission from the first sheet even though 99 originals have already been transmitted to the receiver. Therefore, it cannot be said to be rational in terms of waste of a great deal of time, waste of recording paper and other resources, waste of electric energy. Also, considering the influence on congestion and the like from the viewpoint of monopolization of the telephone line for a long time, it was not preferable in the telecommunications business. If a function to send only the remaining part that could not send the image signal to the memory is added to the fax machine, a special key or a special operation is required to do this. It was not rational in terms of wasting resources, affecting production costs, and wasting time due to complicated operations. or,
Even in this case, there is a drawback that a transmission procedure for transmitting an image signal and, in some cases, a selection signal need to be transmitted, which requires a lot of time. Furthermore, considering what will be done after the line is released, Huaximiri. The fact that the transmission stopped during the memory transmission. Who did it send the memory to? It must be remembered what the image signal is and what the rest of the image signal is to be sent. Therefore, a memory is required, which is not preferable in terms of effective utilization of the memory and saving of electric energy. Considering, for example, the case where a memory transmission is continuously performed by a polling request from the other party, and a call is made for the telephone reservation from the receiver side before the end of sending the last page for each communication, memory consumption In addition, since the sender has to distinguish each communication and change how to deal with it, more keys are added and the operation becomes complicated. In the second method, after the communication is completed and the line is released, the receiver side calls the transmitter side to block the line, and then the receiver must call the sender by some method. The problem here is that the transmitter is performing memory broadcast communication to multiple locations, and at this time, it is very unlikely that the line will be connected, and the receiver will transmit for a long time. Occasionally, people could not be called. <Objective> The present invention, as in the conventional case, when a call request is made from the receiving side between pages during transmission of data of a plurality of pages and a call is made by the operator between the pages, data communication is performed after the call ends. For the purpose of eliminating the inconvenience of having to perform complicated control when resuming, when transmitting multiple pages of data, even if the call request from the receiving side is between pages, without calling the operator, Send the data of the next page, if there is a call request from the receiving side after sending the data of the last page, call the operator, and if the operator answers the call, call the communication line connected to the sending means. An object of the present invention is to provide a communication device for switching to the means. <Embodiment> FIGS. 1 to 6 show an embodiment of the present invention, FIG. 1 is a block diagram of the facsimile machine of this embodiment, and FIG. 2 is an explanatory diagram of a transmission procedure of the facsimile machine of this embodiment. FIGS. 3 and 6 are a part of the control flow chart, FIG. 4 is an operation panel of the facsimile machine, and FIG. 5 is a display explanatory view on the display of the facsimile machine. In FIG. 1, 1 is a modem for communication, 2 is an NCU for connecting a line to a telephone side or a modem, 3 is a modem control unit for controlling 1 and 2, and 4 is for recording a received image on a recording paper. A recording unit, 5 is a reading unit for reading an original by a CCD, 6 is a sensor for detecting the presence or absence of a recording paper original, 7 is a sounding body that emits a warning sound to the operator, a sound for calling, etc.
8 is a display for displaying the status of the facsimile machine to the operator, 9 is a key including a telephone call key, 10 is an operation panel including 8 and 9, 11 is a ROM for storing the control program of the facsimile machine, and 12 is a read Image memory for storing multiple pages of original image data, 13 is RAM including 12, 14 is 1
It is a central control unit that controls ~ 13. Further, in FIG. 4, 15 is an indicator, 16 is a telephone reservation button, 17 is other keys, and 18 is
It is an operation panel containing 15 to 17. In the above configuration, when the receiver sends a signal for the purpose of making a telephone reservation even though the final page is not finished while the fax is being sent to the memory, for example, as shown in FIG. Ignore the signal. In this case, the sending side is sending two sheets of memory, and the recipient wishes to talk with the sender while receiving the first original.
For example, a telephone reservation button such as 16 in FIG. 4 is pressed. Then, the receiver ends the reception of the first original normally, and after receiving the MPS indicating the presence of the next original from the transmitter,
A signal PIP requesting a telephone reservation is sent to the transmitter. The transmitter receives this signal, but does not shift to the call state, and a digital command signal that requests the transmission mode of image data.
After transmitting DCS, the image signal of the second page is transmitted (Fig. 2). FIG. 3 shows the transmitter operation flow chart at the time of FIG. Here, the transmitter does not shift to the call state, but the display on the display as shown in FIG. 4 becomes as shown in FIG. 5, and the receiver wishes to talk with the sender. Tell the sender that Next, when the transmitter finishes sending the last page of the manuscript and sends the last page end signal EOP, the receiver receives it and sends a PIP to the transmitter to shift to the talking state again. The transmitter, in turn, receives this signal and causes the sounding body of FIG. 1 to ring in order to shift to the talking state, and prompts the sender to lift the handset of the telephone (off hook). When the sender receives this and lifts the handset, the transmitter sends out a call request signal PRI-EOP to the receiver, then controls the NCU of FIG. 1 to switch the line to the telephone side, and wait state. Becomes Upon reception of this, the receiver causes the sounding body contained in the receiver to ring and urges the receiver to turn off the handset of the telephone. At this time, a pseudo ring tone may be sent from the receiver to the sender. Next, when the receiver raises the handset of the telephone, the receiver sends a PIP to the transmitter, switches the line to the telephone side, and enters the standby state. For the first time, a call can be made between the transmitting and receiving parties. FIG. 6 shows the transmitter operation flow chart at the time of FIG. Even if the transmitter simply sends the page end signal EOM, the MPS
The same operation as when is sent is performed. <Effect> As described above, according to the present invention, when the call request signal is received between the pages of the data of a plurality of pages, the call processing of the operator is not performed and the data transmission of the next page is performed. Send a procedure signal and then send the next page of data, while after sending the last page of data,
If the call request signal is received while the communication line is connected to the transmitting means, call the operator,
If the operator responds to the call, the communication line connected to the transmission means is switched to the communication means, so that while the data of multiple pages is being transmitted, the operator makes a call between pages according to the call request from the receiving side. Compared with the conventional one, it is not necessary to perform complicated control for resuming data communication after the call ends.
