Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication apparatus such as a facsimile apparatus capable of performing subaddress communication.

[0002]

2. Description of the Related Art In a conventional facsimile apparatus capable of sub-address communication, a sub-address and a communication specification are registered in a memory corresponding to a memory box. Irrespective of this, the receiving capability of the own device is notified to the other device by the initial identification signal.

[0003]

However, in the above-mentioned conventional example, the communication specification of the memory box specified by the sub-address signal is, for example, relay broadcast or transfer, and the receiving capability of these destinations is not the same. If the receiving capability is higher, there is a disadvantage that the receiving capability is limited.

[0004] On the other hand, when the receiving capability of the relay broadcast destination or the transfer destination is lower than the receiving capability of the own device, the reception from the transfer instruction source or the reception from the relay broadcast instruction source is performed by the transfer. Communication with a higher receiving capacity than the receiving capacity of the destination or the receiving capacity of the destination of the relay broadcast is executed, which is extremely wasteful in terms of communication cost and the like.

Accordingly, the present invention is to perform efficient communication in accordance with the transfer destination or the capability of the relay broadcast destination when the communication specification of the memory box specified by the subaddress signal is relay broadcast or transfer. It is an object of the present invention to provide a data communication device capable of performing the following.

[0006]

According to a first aspect of the present invention, there is provided a data communication apparatus capable of sub-address communication, wherein first registration means for registering a receiving capability corresponding to a call destination and memory box. Second registration means for registering the sub-address signal and the communication specification, and when transfer or relay broadcast is selected by the sub-address signal, the initial register having the highest reception capability among transfer destinations or relay broadcast destinations. Control means for transmitting an identification signal.

The second invention of the present application is the first invention, further comprising a selection means for selecting whether or not to output reception information to its own device when performing transfer or relay broadcast,
The control means changes the content of an initial identification signal transmitted when transfer or relay broadcast is selected by a subaddress signal, depending on whether or not to output received information to the own device.

According to a third aspect of the present invention, in the second aspect, the control means selects the transfer or the relay broadcast by the subaddress signal when the output of the reception information is selected to the own device. In this case, the initial identification signal having the highest reception capability among the own device, the transfer destination or the relay broadcast destination is transmitted, while when the output of the reception information to the own device is not selected, the sub-address signal is used. When transfer or relay broadcast is selected, an initial identification signal having the highest reception capability among destinations to be transferred or relay broadcast is transmitted.

According to a fourth aspect of the present invention, in a control method of a data communication device capable of sub-address communication, a first registration step of registering a receiving capability corresponding to a call destination and a memory box A second registration step of registering a sub-address signal and a communication specification; and, when transfer or relay broadcast is selected by the sub-address signal, an initial identification signal having the highest reception capability among transfer destinations or relay broadcast destinations. And a control step of transmitting

According to a fifth aspect of the present invention, there is provided a computer-readable storage medium storing a program for controlling a data communication device capable of sub-address communication, wherein a reception capability is registered corresponding to a call destination. A registration step, a second registration step of registering a subaddress signal and a communication specification corresponding to the memory box, and a transfer destination or a relay destination when a transfer or relay broadcast is selected by the subaddress signal. And a control step of transmitting an initial identification signal having the highest reception capability.

As described above, according to the first, fourth, and fifth aspects of the present invention, when the communication specification of the memory box specified by the sub-address signal is the relay broadcast or transfer, the destination of the relay broadcast or the transfer destination is specified. By transmitting an initial identification signal of the receiving capability and notifying the receiving device of the receiving capability of the data communication device that actually performs reception, it is possible to perform efficient transfer or relay broadcast.

In the second and third inventions, when the relay broadcast or transfer is selected, the content of the initial identification signal to be transmitted is appropriately changed again depending on whether or not the own device outputs the reception information. This makes it possible to make maximum use of the transfer destination, the relay broadcast destination, and the receiving capability of the own device, and to perform communication without waste.
