Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to facsimile communication which allows data transmission even while data is being received.

0002

2. Description of the Related Art While a facsimile machine 16 is receiving data, there are many cases where it is desired to transmit data by the facsimile machine due to urgent requirements.

[0003] In such a case, a facsimile communication system is required that can transmit data even while receiving data.

[0004] As a method of this kind, Japanese Patent Laid-Open No. 61-218
An interruption method for facsimile communication is proposed in Japanese Patent No. 27.

This is an interrupt method for facsimile communication between facsimile terminal devices connected to a storage-enabled facsimile communication network, in which the receiving side sends an interrupt request signal to the transmitting side, and depending on the response from the transmitting side, an interrupt request signal is sent to the transmitting side. an interrupt means for disconnecting the line, and a transmitting means for determining the interrupt request signal and, if the interrupt is permitted, switching the transmitting line to the storable facsimile communication network and continuing the transmission. This is a method in which the transmitting side continues transmission and the receiving side performs interrupt transmission.

According to this method, if there is an urgent transmission request during reception and an interrupt request is input using an interrupt key or the like,
Sends an interrupt request (unable to receive next page) signal to the sending side. If the transmitting side approves the request, it disconnects the line with the receiving side, calls the receiving side again through a facsimile communication network having storage means, and continues transmission. The image signal after switching the communication network is stored in the storage means, and is transmitted when the receiving side is empty.

[0007]

[Problems to be Solved by the Invention] However, in this type of system, since the interrupt is performed after confirming the sending side, it not only puts unnecessary effort on the sending side, but also makes it difficult for the operator on the sending side to If you do not know this, you cannot effectively interrupt.

[0008] The present invention has been devised in view of these points, and an object of the present invention is to enable interrupt transmission to be made during reception without any burden on the transmitting side.

[0009]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention, as shown in the principle diagram of FIG. a data storage means 18 for storing; a communication path switching means 24 for switching between a communication path to the facsimile device 16 and a communication path to the data storage means 18; The apparatus includes a communication path switching requesting means 28 for sending out a path switching request, and a stored data transmitting means 26 for transmitting data stored in the data storage means 18 to the facsimile machine 16.

0010

[Operation] Assume that while the facsimile machine 16 is receiving data, it may be necessary to urgently send a document or the like.

In this case, the caller uses the facsimile machine 16
A communication channel switching request means 28 issues a communication channel switching request. This communication path switching requesting means 28 may be a dedicated switch button or a dialing numeric keypad.

When receiving a communication path switching request from the communication path switching requesting means 28, the communication path switching means 24 switches the communication path to the facsimile device 16 to the data storage means 18.

Therefore, the received data to be received by the facsimile device 16 is stored in the data storage means 18, and during this time, the facsimile communication path is released and the facsimile device is ready for transmission.

[0014] Therefore, the sender makes an emergency facsimile call. When the transmission is completed, the interrupted data can be retrieved by transmitting the received data stored in the data storage means 18 to the facsimile machine 16 by the stored data transmission means 26. This data retrieval after the end of the call may be performed automatically after the end of the call, but the data reception request means 3 provided in the facsimile machine
The transmission request may be made after waiting for a transmission request by 0.

Furthermore, if the facsimile device 16 has an automatic calling means 32 that makes a call at a designated time, reception may overlap with the reserved time. In this case, in order to perform reception and transmission at the same time, if the facsimile machine 16 is receiving at the scheduled transmission time registered in the automatic transmission means 32, the communication path switching means 24 switches the communication path to the facsimile machine 16. Data storage means 1
It is preferable to include a time-based switching means 34 for switching to 8.

[0016]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 2, a digital exchange 10
to the originating facsimile machine 14 and the receiving facsimile machine 1 via trunks (T1, T2, T3), respectively.
6. A data storage means 18 is accommodated.

Here, P1 is the receiving facsimile machine 1
6 and the sending facsimile device 14, P2 is the second communication path connecting the sending facsimile device 14 and the data storage means 18, and P3 is the receiving facsimile device 16 and the data storage means 18. This is the third communication path that connects the .

Further, the digital exchange 10 has a central processing unit 20 for controlling exchange, and this central processing unit 20
A main storage device 22 is connected to. This main storage device 2
2 stores a communication path switching program and a stored data transmission program, which cause the central processing unit 20 to switch between the communication path to the facsimile machine 16 and the communication path to the data storage device 18. and a stored data transmitting means 26 for transmitting the data stored in the data storing means 18 to the facsimile machine.

Furthermore, among the facsimile machines, at least the receiving facsimile machine 16 is provided with a communication path switching requesting means 28. This communication channel switching request means 28 utilizes a dial numeric keypad, and for example, when #111 is pressed, the central processing unit 20 recognizes that it is a communication channel switching request.

The receiving facsimile machine 16 has data reception requesting means 30 for requesting the stored data transmitting means 26 to transmit the received data stored in the data storing means 18 to the facsimile machine 16. This data reception request means 30 also utilizes a dialing numeric keypad, and for example, when #222 is pressed, the central processing unit 20 recognizes that it is a data reception request.

The receiving facsimile machine 16 of this embodiment also has an automatic transmission means 32 . This automatic transmission means 32 is adapted to transmit data to be transmitted at a specified time.

Corresponding to the automatic transmission means 32, the communication path switching means 24 switches the communication path to the facsimile apparatus 16 when the facsimile apparatus is receiving at the scheduled transmission time registered in the automatic transmission means 32. It has a time-based switching means 34 for switching the data storage means 18 to the data storage means 18.

Next, an example of the operation of simultaneous transmission during facsimile reception according to this embodiment will be explained. In this example, it is assumed that seven documents are being sent from the sender's facsimile to the receiver's facsimile, and that the need for facsimile transmission arises when the fifth document is being sent.

In this case, the sender issues a communication path switching request using the communication path switching request means 28 of the receiving facsimile machine 16. Even if this communication path switching request is made,
The communication channel is not switched immediately, but after the reception of the fifth document is completed, a communication channel switching request signal is sent to the communication channel switching means 24.

Upon receiving the communication path switching request signal, the communication path switching means 24 switches the communication path to the facsimile device 16 to the data storage means 18.

Then, the communication path is switched from the first communication path P1 to the second communication path P2, so that the image signals of the sixth and seventh documents to be received by the receiving facsimile machine 16 are stored in the data storage means. 18, and upon completion of reception, sends a completion signal to the originating facsimile machine 14.

During this time, the facsimile communication path P1 is released and becomes ready for transmission. Therefore, the sender makes a facsimile call to a third facsimile device (not shown).

When the transmission is completed, the data reception request means 30 provided in the receiving facsimile machine 16 sends a reception request. Then, the communication path switching means 24 receiving this
switches the communication path from P3 to P2. Therefore, the stored data transmitting means 26 transmits the sixth sheet in the data storing means 18,
The seventh image signal is sent to the receiving facsimile machine 16. When the receiving facsimile device 16 completes reception, a completion signal is sent to the stored data sending means.

It should be noted that even if the receiving facsimile device 16 is receiving data at the time when the automatic calling means 32 makes a reservation for automatic calling, at that time, the time response switching means 3
4 is activated and the same operations as described above are automatically performed.

[0031]

According to the present invention, an interrupt call can be made only by operating the receiving facsimile machine without requiring any operation from the sending facsimile machine.
