Abstract

PROBLEM TO BE SOLVED: To enable high-speed communicating and to prevent a user from waiting by executing a dual processing where reading and recording are not processed together at the time of whole dual communication and they are processed together at the time of half dual communication. SOLUTION: A control circuit 20 judges whether information of the signal line 24a of an operating part 24 is whole dual communication or half dual communication. At the time of whole dual communication, it is displayed that reading and writing are not executed in a display circuit 26 by the level 1 signal of the signal line 20g, a control part 24 receives information of the operation in the operating part 24 with the signal line 24a so as to transmit it, reception information is displayed in a display part 22 with the signal line 20f and reading for copying and memory storage and the recording of memory reception information are not executed. At the time of transmission in half dual communication, transmission is executed by pre-procedure, picture transmission and post-procedure. At the time of reception, the half dual communication of pre-procedure, reception/recording and post-procedure are executed and memory storage for memory transmission is executed. Thus, high-speed communication is secured at the time of whole dual communication and the user is not made to wait at the time of half dual communication.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention is particularly concerned with V.I. 34 half-duplex communication and V.34. 34 relating to a facsimile machine capable of full-duplex communication.

[0002]

2. Description of the Related Art Most conventional facsimile machines use half-duplex communication. For full-duplex communication, a NACK tone is transmitted when an error is detected during image signal reception, and the transmitter transmits a signal. And the frame is retransmitted from an erroneous frame.
The ACK tone is band divided.

[0003]

However, with the recent boom in personal computers, facsimile machines are also used for data communication, that is, V.70. It is expected that the number of those having 34 full-duplex communication functions will increase. V. here. In the full-duplex communication 34, the signal transmitted by itself is canceled by echo cancellation, and the signal from the partner device in the same band is received.

By the way, V. In 34, half-duplex communication has a high communication speed, and it is difficult to secure S / N. If full-duplex communication is used, it is more difficult to secure S / N. With the same design as a conventional facsimile machine, V. 34
There was a drawback in that it could not make full use of the full-duplex modem function, and it became a low-speed data communication.

[0005] The present invention relates to 34 full-duplex communication and V.34. 3
It is an object of the present invention to provide a facsimile device capable of effectively performing the half-duplex communication of 4 above.

[0006]

Means for Solving the Problems The first invention of the present application is:
V. 34 full-duplex communication means and V.34. 34 in a facsimile machine having half-duplex communication means. 34, when the half-duplex communication is performed, both the reading operation and the recording operation, or either one of them is permitted. 34, when the full-duplex communication is performed, by prohibiting both the reading operation and the recording operation, V.34. In full-duplex communication of No. 34, since the dual processing of simultaneously performing the reading operation and the recording operation is not performed, it becomes possible to secure high-speed communication. During the half-duplex communication of 34, a dual process of simultaneously performing a reading operation and a recording operation is performed, and it is possible to provide a facsimile device that does not make a user wait.

The second invention of the present application is to perform V.V. operation when recording operation of memory reception information or copying operation, reading operation of original information for memory transmission and memory storage are being executed. If half-duplex communication of No. 34 is selected, half-duplex communication is performed in addition to the operation up to now, and V.34. 3
If full-duplex communication of No. 4 is selected, the current reading operation or recording operation is interrupted, and V.V. By switching to full-duplex communication of No. 34 and displaying the fact, V.34 during the reading operation and the recording operation. Proper operation can be obtained if 34 half and full duplex communications are selected.
