Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a proxy communication request system in a facsimile system. With the development of the information society in recent years, a large amount / high-speed transmission of various information has been performed. Facsimile is also an effective means of information transmission.
It has been developing rapidly in recent years. However, if an abnormality or the like (out of paper, etc.) occurs in the facsimile, communication cannot be performed thereafter until the operator's recovery work is performed. Therefore, a communication proxy is required until restoration by the operator is performed.

[0002]

2. Description of the Related Art In a conventional facsimile system, there are the following communication proxy systems when some abnormality occurs. (1) Communication messages, list information and the like are stored in a memory such as an IC memory and a magnetic memory, and after the abnormality is recovered, printing is performed by the recording unit. In this case, the main control unit detects the occurrence of an abnormality such as paper out, and when the abnormality is detected, the memory control unit is instructed to control the memory by the memory control unit. (2) When an abnormality occurs, the telephone number registered in advance is notified of the abnormality by a voice function or the like, and the operator's recovery work is prompted.

[0003]

However, in the case of the conventional facsimile system as described above, in the former case, a large amount of storage medium is required for storing the communication message, which increases the cost. There was a problem. Further, in the latter case, it is impossible to deal with the occurrence of an abnormality at night. For this reason, there has been a problem that the device of the popular machine class is in a device stopped state for a long time.

The present invention has been made in view of the above conventional problems, and even in a facsimile apparatus having no memory function or voice function, the communication agency at the time of occurrence of an abnormality is low cost and easy at night. The purpose is to provide a proxy communication request method that can be performed by

In FIG. 1, 2 is a public line, 3 is an extension exchange, 6 and 7 are a plurality of facsimile devices connected to the public line 2 through the extension exchange 3, and 18 is a facsimile device 6 in which facsimile communication is impossible. Detecting means for detecting the release of the generated or disabled state, and 19 is a request / release means for requesting or canceling the absent transfer to the proxy facsimile machine (7) to the extension exchange.

[0006]

[Function] Due to the increase in the amount of information transmission, general companies have introduced various extension exchanges. Extension switches have come to have various functions by digitization. Call forwarding is one of the functions. This is because if the destination telephone number is notified to the extension exchange in advance in the case of absence,
This is a function to automatically transfer a call to the corresponding number to the destination number. Further, as the cost of facsimile becomes cheaper, a plurality of devices have been introduced.
In the present invention, the absent transfer function of the extension exchange is used to transfer to another facsimile when the facsimile is abnormal.

It is detected whether or not the facsimile communication is disabled, and if it is generated, the extension exchange is requested to make an absent transfer to the substitute facsimile machine. After that, when the communication disabled state is released, the absent transfer to the facsimile machine acting on behalf of the extension exchange is released. As described above, even in an inexpensive facsimile machine having no memory function or voice function, the communication can be easily performed at night at a low cost when an abnormality occurs, and the facsimile work is not stopped for a long time.
