Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device to which an answering machine can be connected.

[Conventional Technique #i] Conventionally, facsimile apparatuses have been provided which have a connection part for a child telephone and to which an answering machine can be connected.

In this facsimile machine, when there is a call from an external communication device, the answering machine is first activated,
While sending a response message, the facsimile machine determines whether the called party is a facsimile machine or a telephone call.If it is determined that the called party is a facsimile machine, one line is connected to the facsimile machine, and the facsimile machine It is designed to start the reception operation.

[Problems to be Solved by the Invention] However, in the conventional example described above, in order to determine whether the called party is a facsimile or a telephone while the answering machine is sending a response message, a facsimile signal (FC signal) from an external communication device is used. There was a drawback that the answering machine conflicted with the answering message, making it impossible to determine whether the called party was a facsimile.

For this reason, the user has to be careful when inputting so that the output of the response message is sent a little, which is troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile device that can reliably determine whether a call is being called, regardless of the timing at which a response message is sent.

[Means for Solving the Problems] The present invention provides a facsimile device to which an answering machine can be connected, and when a call is received, the line is connected to the answering machine before determining whether the called is a facsimile or a telephone. The system is characterized in that the call is determined by attenuating the signal from the answering machine, and after determining that the call is a facsimile, the line is connected to the facsimile main body.

[Function] In the present invention, by attenuating the response message from the answering machine and avoiding collision between the response message from the answering machine and the facsimile signal (FC signal) from the external communication device, it is possible to ensure the determination of the called party. can be done.

[Example] FIG. 1 is a circuit diagram showing one embodiment of the present invention.

This facsimile machine includes an answering machine 1 equipped with a message recording/reproducing device, a slave telephone 2, an off-footer detection circuit 3 of each telephone 1.2, and an H1 relay 4 operated by the hoo and king of the answering machine 1. It has an H2 relay 5 that operates when the child telephone 2 is hooked, and an attenuator 6 that attenuates the signal from the answering machine 1.

This facsimile device also includes a CML relay 7 for switching between a telephone and a facsimile body, a Ci detection circuit 8 for detecting Ci (Kohlinge indicator), an audio transformer 9, and an FC detection circuit lO for detecting an FC signal.
, the line transformer 11, the modem 12 that performs modulation and demodulation, and the control of the entire device, especially the switching of each of the relays 4, 5, and 7, the control of the amount of attenuation of the attenuator 6, and the determination of whether the called is a facsimile or a telephone. It has a CPU 13 that performs.

FIG. 2 is a flowchart illustrating the operation of this embodiment when a call is received. First, the facsimile machine receives the call and determines that it is Ci. When this happens (S2), the CPU 13 issues a command to the 7-tone attenuator 6 to attenuate the signal from the answering machine 1, and the attenuator 6 attenuates the signal from the answering machine 1 (S3).

Then, the FC detection circuit IO starts detecting FC (S4), and if there is an FC signal, it is determined that the called device is a facsimile, and if no FC signal is detected for a certain period of time, it is determined that the called device is a telephone. (S5. S6).

Then, if it is determined that the called party is a facsimile, C
The ML relay 7 is switched to the modem 12 side (S9), the attenuation by the attenuator 6 is canceled (S10), and facsimile reception operation is performed (S11).

If it is determined that the called party is a telephone, the attenuation of the attenuator 6 is canceled (S7), and the answering machine 1 sends a response message and records a business message (S7).
S8). Then, when the answering machine is finished, it returns to standby.

[Effects of the Invention] As described above, according to the present invention, by providing a circuit that attenuates a response message from an answering machine, it is possible to reliably determine whether the called party is a facsimile or a telephone. Therefore, it is possible to eliminate the trouble that the user has to think about how to leave a message on the answering machine.
