Abstract

PURPOSE:To provide an appropriate operation corresponding to the plural kinds of connected telephone sets by providing a registering means on which the kind of respective telephone set is registered and changing control when an incoming call is received based on registration information. CONSTITUTION:The kind of telephone set in accordance with a telephone number is registered on a registration circuit 46. In this case, it is assumed that an automatic answering telephone is registered on the telephone set A, and an ordinary telephone on the telephone set B. A control circuit 50 performs the control so as to hold speech by detecting a signal CNG sent from an opposite side when detecting the closure of a DC loop is detected when an automatic answering telephone mode is selected and the telephone set is the ordinary telephone set B 4, or, detecting silence. Also, the circuit 50 detects sent signal CNG or silence when the telephone set connected to a line on which the DC loop is detected is the telephone set A 2, and performs such control to transfer a mode to a communication mode when such signal is detected, and to continue automatic answering recording when it is not detected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus capable of connecting a plurality of telephones.

[0002]

2. Description of the Related Art Conventionally, in a facsimile apparatus to which a plurality of telephones can be connected, the plurality of connected telephones are treated as the same type of telephones.

That is, judging from the side of the facsimile machine, when the incoming call mode is the answering machine mode, it is judged that all of the plurality of telephones are answering machines, and the FAX / TE.
In the L automatic switching mode, it has been determined that all of the plurality of telephones are normal telephones.

[0004]

Therefore, for example, two telephones can be connected to the facsimile machine, one is an answering machine, the other is an ordinary telephone, and an answering machine mode is selected. If there is an incoming call and the operator answers with a general telephone, the facsimile machine determines that the answering machine has answered and detects the CNG signal or the silence, and these signals are erroneous. If it is detected, there is a drawback that the communication is switched to facsimile communication and the communication becomes impossible.

An object of the present invention is to provide a facsimile apparatus which can obtain an appropriate operation depending on the types of telephones to be connected.

[0006]

According to the present invention, in a facsimile apparatus to which a plurality of telephones can be connected, there is provided registration means for registering the type of each telephone, and the control at the time of incoming call is changed based on this registration information. It is a thing.

Specifically, when the answering machine mode is selected, when the closing of the DC loop is detected and the normal telephone is connected to the line in which the DC loop is detected, the other party When a call is made without detecting the CNG signal transmitted from the device or detecting silence, and not switching to the communication mode, and the voice mail is connected to the line where the DC loop is detected, The CNG signal transmitted from the other party is detected for a predetermined time, or the silence is detected. If these signals are detected, the communication mode is entered. If these signals are not detected, the message recording is continued.
