2. Description of the Related Art Conventionally, in general, when a facsimile is mistakenly connected to a line on which a telephone is installed, even if the other telephone side disconnects the line, the facsimile repeats a predetermined retransmission, so that the telephone is called each time. You have to hang up and disconnect the line, and you can't do anything from the telephone side. Similarly, the facsimile side can't recognize whether the other party is a telephone or not, and you can resend it a preset number of times. Resulting in.

Conventionally, for example, Japanese Patent Laid-Open No. 63-3102.
In the facsimile device reported in Japanese Patent No. 58,
It has identification means for identifying the other party and line switching means for switching the line. When the switching signal is input according to the voice information from the called facsimile machine, the line is connected to the telephone, and when it is not input, the facsimile is connected. Reception can be transitioned. However, in this facsimile device, the line can be switched from the facsimile device to the telephone or to the normal facsimile reception. However, when the line is erroneously connected as described above, the telephone side has the above-mentioned identification means. Since there is no line switching means, the operator can only disconnect the line by placing the receiver.

[0004]

As described above, in the conventional telephone and facsimile machine, once the facsimile erroneously transmits the facsimile to the telephone, the telephone side as described above is identified by the other party and the line switching means. Even if the telephone side disconnects the line, the facsimile side connects the line until it reaches the preset number of retransmissions, and has to answer the phone each time.
In addition to the interruption of business each time, the facsimile side makes a line connection every time it resends meaninglessly, so that there is a problem that a telephone charge is added each time.

Therefore, according to the present invention, when a facsimile erroneously connects a line to a telephone, the facsimile communication can be normally terminated without performing unnecessary retransmission from the facsimile, resulting in useless time and useless telephone charges. It is an object of the present invention to provide a telephone and a facsimile device that can omit the above.
