Abstract

PURPOSE:To send information on emergency from one set of facsimile equipment by switching a line even in receiving the information from other station to a communication line for emergency communication automatically at the time of detecting the transmission of information through the emergency communication use communication line. CONSTITUTION:When information is sent through a communication line 12 for emergency communication from other station, a changeover device 13 is switched by a microcomputer built in a controller 15 and the communication line 12 is connected to a facsimile equipment 20. When the transmission of information requiring emergency is finished and the transmission of information through the communication line 12 is interrupted, the changeover device 13 is switched to the original state. When the information is sent through the communication line 12, the changeover device 13 is switched and at the same time a signal is outputted from an external output device 16 by the control of the controller 1 to drive a voice output device 18 and an alarming device 19 thereby informing the information requiring emergency.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a facsimile machine that automatically switches between a regular communication line for one facsimile machine and an emergency communication line provided for emergency communication. The present invention relates to a communication line switching device.

[Conventional technology]

Conventionally, in order to alleviate the inconvenience of not being able to send urgent information to a station equipped with only one facsimile, if the facsimile is receiving information from another station, K. Stations that frequently receive urgent information have adopted the configuration shown in FIG. 3.

In the figure, +11 and +2) are communication lines, (3) is a private branch exchange, 141 and 151 are lines, (6) is a regular facsimile, and (7) is a facsimile for emergency communication.

Private branch exchange (3) for two communication lines (1) and (2)
Two facsimile machines 161 and 171 are connected via a communication line, and even when one facsimile IJ is receiving information from another station, it is configured to be able to send information through an unused communication line.

[Problem that the invention seeks to solve]

The conventional method described above requires two facsimile machines, which is a heavy economic burden, and is also inconvenient in that it cannot send information if both facsimile machines are receiving information from another station. is not resolved.

This invention has been made in view of the above circumstances, and is a communication line that provides a configuration that alleviates the inconvenience that a single facsimile machine cannot send information while it is receiving information from another station. The purpose is to provide a switching device.

[Failure to solve the problem]

The facsimile communication line switching device of the present invention includes a switching device for switching between a regular communication line for the facsimile and an emergency communication line provided for urgent communication, and a communication line for emergency communication from the other party. a detection device that detects the transmission of information over the line; and a control device that includes a microcomputer and controls switching between the regular communication line and the emergency communication communication line for the facsimile by the switching device in response to the detection by the detection device. It is equipped with the following.

[Effect]

Under the control of the microcomputer built into the control device, when the detection device detects the transmission of information from another station over the emergency communication line, even if the facsimile is receiving information from another station over the regular communication line, , the communication line for the facsimile is automatically switched to the communication line for emergency communication, and urgent information is received.

The switching device (
13) is switched and the communication line (12) is connected to the facsimile (20).

Transmission of urgent information has been completed, communication session II (12)K
When information is no longer being transmitted, the detection device (14) K is detected and the switching device (13) is switched back to its original state under the control of a microcomputer containing a control value R (15).

When information is sent from communication line (12) K,
As soon as the switching device (13) is switched, the control Ilc
The external output device M! is controlled by the position (15). (16), audio output device (1B), alarm device (1B),

When external output is not required, external output can be stopped by setting information using the terminal (17).

Figure WJ2 is a flowchart showing the control procedure of the control device (15).

Checking the detection state of the detection device (14) (31),
It is determined whether information is transmitted or not (32
), if the information has not been transmitted, the process returns to step (31)K after a one second time delay (33). If information is being sent, switch the switching device (13)
(34).

Next, it is determined whether or not no-voltage contact output is necessary (3

The embodiment described above is configured to provide a non-voltage contact output capable of ringing a bell in order to issue a thorough warning when urgent information is received.

〔Effect of the invention〕

As described above, according to the present invention, when an emergency is required, information can be sent to a single facsimile using an emergency communication line provided in addition to the regular communication line, which is different from the conventional communication line. In addition, there is no need to use two facsimile machines, which has the effect of reducing the economic burden.
