Abstract

PURPOSE:To perform the continuous transmission of image data from in incoming call side with charging on a call issuing side after the transmission of the image data from the call issuing side is completed. CONSTITUTION:An opposite station address and the image data for transmission are registered on storage parts 5a, 5b from operating parts 2a, 2b and image data reading parts 4a, 4b in advance. A control part 3b, after receiving the image data from outgoing side facsimile equipment 1a, retrieves the presence/ absence of the image data awaiting transmission for the outgoing side facsimile equipment 1a, and requests a transmission right to the facsimile equipment 1a when the image data awaiting transmission is retrieved, and transmits retrieved image data to the outgoing side facsimile equipment 1a by reading out from the storage part 5b after the transmission right is transferred.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile communication system, and more particularly to a facsimile communication system capable of mutually exchanging transmission rights.

[0002]

2. Description of the Related Art A conventional facsimile communication system, as a first conventional example, is one-way communication from a calling side to a called side when transmitting image data, and the called side to the calling side. When transmitting image data, a method is used in which after the call is released, the called side makes a call, and after the call is connected, the image data is transmitted.

In the second conventional example, after the call connection, the transmission right is forcibly transferred from the calling side to the called side, and if there is image data from the called side to the called side, the called side is called. It is a system in which image data is transmitted from the caller side to the calling side.

[0004]

In the above-mentioned conventional facsimile communication system, in the case of the first conventional example, the image data is only transmitted from the calling side to the called side between one call connection and a call release. Therefore, there is a problem that the image data cannot be transmitted from the called side due to the charging of the calling side.
Further, in the case of the second conventional example, there is a problem that efficient communication cannot be performed because the calling side always transfers the transmission right even if there is no image data from the called side.

[0005]

According to the facsimile communication system of the present invention, a destination station address and image data for transmission are registered in a facsimile apparatus which is connected to a communication network and can mutually exchange the transmission right of image data. Registration means,
When receiving image data from the partner station, searching means for searching for registration of image data waiting to be transmitted to the station address of the partner station in communication, and communicating when the image data waiting to be transmitted is searched. And a transmission means for transmitting the searched image data after the transmission right is transferred from the other station.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, this embodiment is constructed by connecting fax machines 1a and 1b to each other via a communication line 10.

Facsimile machines 1a and 1b respectively include operation units 2a and 2b, control units 3a and 3b, image data reading units 4a and 4b, and storage units 5a and 5b.

The operation units 2a and 2b each include an operation switch and the like, and the facsimile machines 1a and 1b operate in response to an operation on the operation units 2a and 2b.

The control units 3a and 3b are respectively the operation units 2a and
In response to a command from 2b, the facsimile machines 1a and 1b
Control the overall behavior.

The image data reading units 4a and 4b read image data for transmission in response to commands from the operation units 2a and 2b, respectively.

The storage units 5a and 5b are respectively the operation units 2a and 5a.
In response to the command from 2b, the destination station address and the image data for transmission read by the image data reading units 4a and 4b are registered.

Next, the operation of this embodiment will be described.

First, the facsimile machines 1a and 1b
Inputs the partner station address using the operation units 2a and 2b, respectively, and stores the input partner station address in the storage units 5a and 5b.
In addition, the image data reading units 3a and 3b read the image data for transmission and register the image data in the storage units 5a and 5b.

Operation unit 2 of the facsimile machine 1a on the calling side
A case will be described in which a is operated to call the destination station address as the station address of the facsimile apparatus 1b on the receiving side and the image data is transmitted to the facsimile apparatus 1b.

Control unit 3 of the facsimile machine 1b on the called side
After the reception of the image data from the facsimile apparatus 1a, b searches the storage unit 5b for image data whose destination address is the station address of the facsimile apparatus 1a. If there is image data as a result of the search, the control unit 3b requests the transmission right from the facsimile apparatus 1a.

When the control unit 3 of the facsimile apparatus 1a receives the request for the transmission right, the control unit 3 transfers the transmission right.
Delegate to. When the control unit 3b of the facsimile device 1b accepts the transfer of the transmission right, the control unit 3b transmits the image data retrieved by the storage unit 5b to the facsimile device 1a, and then transfers the transmission right to the facsimile device 1a. The control unit 3a of the facsimile apparatus 1a accepts the transfer of the transmission right and then releases the call.

In this way, in this embodiment, after the facsimile machine 1a on the calling side transmits image data, the facsimile machine 1b on the calling side is transmitted from the facsimile machine 1b on the called side.
Image data can be continuously transmitted to a. Therefore, the calling side is charged a fee for the transmission of the image data from the called side facsimile device 1b.

[0020]

As described above, according to the present invention, the registration means for registering the destination station address and the image data for transmission, and the station address of the partner station in communication when receiving the image data from the partner station. A search means to search for the presence or absence of registration of image data waiting to be transmitted, and when the image data waiting to be transmitted is searched, the transmission right is requested to the communicating station, and after the transmission right is transferred from the station. By including the transmitting means for transmitting the searched image data, the image data can be continuously transmitted from the callee side after the image data has been transmitted from the callee side, and the callee side is charged by the callee side. The effect is that image data can be transmitted.
