Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a transfer means for a facsimile machine.

〔overview〕

In the present invention, in a means for transferring image data from a calling facsimile machine to a forwarding facsimile machine via a called facsimile machine, the telephone number of the forwarding facsimile machine set in the called facsimile machine is transmitted to the calling facsimile machine. By transferring the image data to the receiving facsimile machine, it is possible to directly transfer the image data without having to store it in the receiving facsimile machine.

[Conventional technology]

In the conventional example, the receiving side temporarily stores the image signal information sent from the other party in a memory, and then ends the communication. Thereafter, the receiving facsimile machine makes a call according to the forwarding destination number inputted in advance, and transmits the image signal information stored in the memory to the forwarding destination facsimile machine.

[Problem that the invention seeks to solve]

In such a conventional example, the image signal information is once stored in the receiving facsimile device and then transmitted to the destination facsimile device, which has the drawback of using a large amount of expensive memory for image signal storage.

The present invention aims to eliminate such drawbacks and to provide a data transfer device that does not require a memory for storing image signals.

[Means for solving problems]

The present invention provides a first facsimile device for transmitting image data;
In a data transfer device included in a second facsimile device that relays this image data and a third facsimile device that transfers this image data, each of the first and second facsimile devices is connected to the third facsimile device. The second facsimile device includes a storage means capable of storing subscriber number data, and the second facsimile device includes an operation section that stores the subscriber number data related to the third facsimile device in the storage device by operation, and a call from the first facsimile device. The first facsimile apparatus includes signal generating means for generating a procedure signal including subscriber number data stored in the storage means of the own apparatus in response to a signal, and the first facsimile apparatus transmits the second facsimile apparatus in response to a calling signal from the own apparatus. Signal analysis means that extracts subscriber number data from the procedure signal arriving from the device and stores it in the storage means of the own device, automatically calls the subscriber number data stored in the storage means of the own device and automatically converts the image data. It is characterized by having an automatic transmission means for transmitting a transmission.

The first and second facsimile devices can be constructed and used as devices having the same standard and configuration.

[Effect]

The receiving facsimile machine stores the forwarding destination telephone number given by the operation, and transmits the stored forwarding destination number as a procedure signal to the calling facsimile machine. The originating facsimile machine analyzes the received procedure signal and outputs the forwarding destination number. A call is made to this transfer destination number based on instructions from the control section, and when the transfer destination is connected, image data is sent out.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1st
The figure is a configuration diagram showing this embodiment.

As shown in FIG. 1, this embodiment includes a reading section 1, a recording section 2, an image processing section 3, a modem section 4, a network control section 5,
It includes a procedure signal generation section 6, a procedure signal analysis section 7, a control section 8, a transfer destination number storage section 9, an operation section 10, and a calling section 11. That is, in this embodiment, each of the first facsimile device that transmits image data and the second facsimile device that relays this image data can store subscriber number data related to the third facsimile device to which the image data is transferred. The second facsimile device includes a forwarding number storage section 9 which is a storage means, and the second facsimile device stores subscriber number data related to the third facsimile device in the storage device by operation. The first facsimile apparatus includes a procedure signal generating section 6 which is a signal generating means for generating a procedure signal including subscriber number data stored in a storage means of the own apparatus in response to a calling signal from the own apparatus. A procedure signal analysis section 7, which is a signal analysis means for extracting subscriber number data from a procedure signal received from the second facsimile device in response to a paging signal and storing it in a storage means of the own device, stores it in the storage means of the own device. The system is equipped with a calling section 11, which is an automatic calling means for automatically calling subscriber number data and automatically sending image data, and a network control section 5.

FIG. 2 is a diagram showing an example of a communication procedure according to an embodiment of the present invention.

Next, the operation of this embodiment will be explained based on FIGS. 1 and 2.

In the receiving facsimile machine, the operator uses the operation unit 10 to enable the transfer function and to set the telephone number of the destination facsimile machine in advance. The control section 8 manually enters the telephone number of the destination facsimile device from the operation section 10 and writes it into the destination number storage section 9 . When a call arrives in this state, the network control unit 5 closes the line, and then the procedure signal generation unit 6
generates a procedure signal containing information for enabling the transfer function or telephone number information of the transfer destination outputted from the transfer destination number storage section 9 in accordance with an instruction from the control section 8 . The modem section 4 modulates the procedure signal necessary for transmission over the line, and transmits it to the line via the network control section 5. On the other hand, the originating facsimile device demodulates the procedure signal sent from the incoming facsimile device via the network control section 15 in the modem section 4, and the procedure analysis section 7 detects the information of the forwarding telephone number included in the procedure signal. and stored in the transfer destination number storage section 9. When communicating with the forwarding destination facsimile machine thereafter, the control section 8
The calling section 11 makes a call in response to the instruction from the forwarding destination facsimile device, encodes the image information read by the reading section 1 in the image processing section 3, modulates it in the modem section 4, and then sends it to the network control. The image signal is sent out via the section 5, and a transmission operation is performed to the destination facsimile machine.

That is, as shown in FIG. 2, when the called facsimile machine starts up in response to a call signal from the calling side and the line is closed, the first thing that happens is a procedure signal from the called facsimile machine instructing transfer. A transfer destination instruction signal is sent. When the originating facsimile device confirms the transfer instruction, it returns a response signal. Next, the receiving facsimile device sends out a transfer destination information signal containing information on the telephone number of the transfer destination facsimile device. The originating facsimile device receives the forwarding destination information signal, stores the telephone number of the forwarding destination facsimile device in the forwarding destination number storage section 9, sends out a response signal, and temporarily ends the communication.

The calling facsimile machine then closes the line again and
Based on the telephone number of the destination facsimile device stored in the destination number storage section 9, the calling section 11 makes a call to the line to call the destination facsimile device, and receives an initial identification signal from the destination facsimile device. After that, the procedure signal and training signal are sent out. When it continues to receive response signals, it sends out an image signal, performs normal facsimile communication, and then sends out a termination signal to end the communication.

〔Effect of the invention〕

As explained above, when the transfer function is set in advance, the receiving facsimile machine notifies the calling facsimile machine of the telephone number of the forwarding destination facsimile machine using a procedure signal. Since the facsimile device calls the destination facsimile device for communication using the destination facsimile device number notified by the procedure signal, compared to conventional devices, the receiving facsimile machine does not require a large amount of memory for image signal M storage. This has the effect of reducing the cost of the device.
