[Industrial application field]

The present invention relates to a data communication system, and more particularly to a facsimile communication system with improved control when a facsimile device is not placed in an automatic receiving state.

There is a type in which a facsimile device is connected to a computer via a public communication line and data is transferred between the facsimile device and the computer. Due to the structure of such a facsimile communication system, there are cases in which a facsimile procedure for successful data transfer between a facsimile device and a computer cannot be carried out.

[Conventional technology]

In the conventional facsimile communication system as described above, when a computer makes a call to a facsimile device to transfer data, if the facsimile device is in automatic reception mode, the data signal sent from the facsimile device is In response, a facsimile procedure is automatically initiated between the computer and the facsimile device.

However, if the facsimile machine is not set to automatic reception, it will generate a ring tone, but if the operator picks up the handset in response to this, the phone will become unanswered. There is a problem with it being stored away.

[Problem to be solved by the invention]

The present invention was invented in order to solve the above-mentioned drawbacks, and provides a data communication system that can give voice guidance to the operator of the called device and allow the data transmission procedure to proceed normally even if the called device is not in an automatic receiving state. Its purpose is to provide.

[Means to solve the problem]

FIG. 1 shows a block diagram of the principle of the present invention. In this figure, 10 is a called device which causes the transmission of a called identification signal and automatic setup to the receiving state in response to a calling signal which is received only when set to the automatic receiving state. otherwise, activation of the setup actuator causes setup to the receive state. A calling device 20 is connected to the called device 10 via a communication line 22, and transmits the calling signal to the called device 10 prior to transmitting data to the called device 10. Send to. The calling side device 20 of a data communication system that performs data communication between both devices configured as described above receives a called identification signal from the called side device 10 within a specified time after transmitting the calling signal. A detection circuit 24 detects whether or not
and a voice guidance output unit 26 for transmitting voice guidance information for setting up the called device 10 to the receiving state, and the detection circuit 2
The characteristic part of the present invention is that the voice guidance information is transmitted from the voice guidance output unit 26 to the called side device 10 when the called identification signal is not detected within the specified time by the voice guidance output section 26. be.

[Effect]

When transmitting data from the calling device 20 to the called device 10 via the communication line 22, a calling signal is sent to the called device 10.

When the called device 10 is set to the automatic receiving state, a called identification signal in response to the calling signal is returned to the calling device 20. When the detection circuit 24 detects that the called identification signal is received within a specified time, the calling device 20 starts normal data transmission.

When the called device is not set to the automatic receiving state and does not receive the called identification signal within the specified time, the detection circuit 24 outputs a non-set state detection signal. The detection signal activates the voice guidance output unit 26, which transmits voice guidance information to the called side device via the communication line 22 to set the called side device 10 to a receiving state.

The voice guidance information is emitted from the sound emitter 30 on the called device side. This voice guidance is a signal that the called device 10 wants to activate the existing setup activation section.

Therefore, even if the called device 10 is not set to the automatic receiving state, it is possible to prevent the system from falling into a dormant state.
