There are various types such as Kyu II.

Additionally, there is an answering machine that can be remotely controlled using a telephone line, and it has become popular in ordinary households. However, this answering machine! The reality is that it is not possible to connect the fil and the telephone control device to the same telephone line.

(Problems to be solved by the invention) This invention was made in view of the above circumstances.
The object is to provide an excellent telephone control device that can be used on the same telephone line as an answering machine.

[Structure of the Invention] (Means for Solving the Problems) A telephone answering machine that is connected to the same telephone line as an answering machine that responds to a specific number of ringing signals, and that a specific signal is input while the answering machine is responding. A switching signal receiving section is provided which detects from the telephone line and issues a starting signal, and a control means is provided which starts a telephone control operation in response to the starting signal from the switching signal receiving section.

(Function) When a specific signal is input from the telephone line while the answering machine is answering, the answering machine receives it as a switching signal and starts telephone control operation.

(Example) An example of the present invention will be described below with reference to the drawings. In the drawings, the same parts as in FIG. 2 are designated by the same reference numerals.

As shown in FIG. 1, the main body 1 includes a microprocessor 10
The microprocessor 10 includes an incoming call detection section 11, an incoming call lamp 12, a DTMF receiving section 13 which is a switching signal receiving section, a synthesized voice sending section 14, and a relay 1.
5.16 is connected.

The microprocessor 10 performs overall control of the telephone control device.

The incoming call detection section 11 is connected to a telephone line via a capacitor 17 and a resistor 18, and detects a ringing signal (bell signal) sent from the telephone line. The incoming call lamp 12 lights up when the incoming call detection section 11 detects a ringing tone signal and when there is a lighting command from the microprocessor 10.

The DTMF receiving section 13 includes a capacitor 17, a resistor 18, a transformer 19, a resistor 20.21, a diode 22.23,
It is connected to the telephone line via the normally closed side of the relay contact 15b, and the relay contact 15a1 transformer 24
, and the normally open side of the relay contact 15b to the telephone line, and decodes the code signal (signal from the telephone) sent from the telephone port 1i1L.

The synthesized voice transmitter 14 outputs a dragon horn information signal in response to a command from the microprocessor 10, and its output end is connected to a telephone line via a relay contact 16a, a transformer 24, and a relay contact 15a. ing.

Furthermore, the microprocessor 10 includes an adapter output section 31 for outputting a device control signal, an adapter input section 32 for receiving a device response signal, a device setting switch/password setting switch 33, an out-of-home set switch 34, and an out-of-home set lamp 3.
5 is connected. Further, a device control switch 36 for manual operation and a device operation monitor lamp 37 are connected to the adapter 2 .

A line T for the resident's own telephone is branch-connected to the telephone line, and an answering machine 50 is connected to the line T. The main body 1 also includes a power supply section 38 for receiving operating voltage.
is provided, and this power supply section 38 is connected to a commercial AC power supply 40.

Next, the operation in the above configuration will be explained.

The outing set switch 34 is now on, and the answering machine H1 is on.
It is assumed that so's outing set switch (not shown) is turned off.

In this state, when a ringing tone signal is sent from the telephone line, it is detected by the incoming call detection section 11. When the incoming call detecting section 11 detects the Mth ringing signal, for example, the fourth ringing signal, the microprocessor 10 excites the relay 15, turns on the contact 15a, and closes the telephone line. and,
A voice information signal corresponding to a message indicating that there is no one in the dwelling unit is outputted from the synthesized voice sending section 14, and the relay 16 is energized to turn on the contact 16a. This voice information signal is transmitted to the caller via the telephone line.

When the caller confirms that the caller is absent and enters a code signal corresponding to the PIN number, the code signal is transmitted from the telephone line to relay contact 15a.
, )-lance 24 and the normally open side of the relay contact 15b, the signal is transmitted to the DTMF receiving section 13, where it is decoded. Here, the password is, for example, 0000 to 99.
99, 10,000 arbitrary number combinations.

The microprocessor 10 determines whether the content of the code signal to be decoded, that is, the PIN number, matches a preset PIN number. If they match, the microprocessor 10 sends a voice information signal corresponding to a message to that effect to the synthesized voice sending unit 14. output from. Therefore, the caller confirms that control is possible and inputs a control command (code signal) for the desired device. This control command is decoded by the DTMF receiving section 13, and a corresponding device control command is sent to a predetermined device via the adapter 2. Then, the equipment operates according to the equipment control command, and a message indicating the operating status is sent (for example, "The air conditioner has been turned on.")
A voice information signal corresponding to the voice information signal is transmitted from the synthesized voice transmitter 14 to the telephone line and transmitted to the caller.

However, when the input PIN does not match the preset PIN, the microprocessor 10 determines that it is a prank by a third party if this happens twice,
The relay 15 is de-energized, the contact 16a is opened, and the telephone line is forcibly opened.

In this case, there may be an input error by the caller, so the first mismatch is allowed.

Next, a case where the going out setting switch 34 is on and the outing setting switch of the answering machine 50 is on will be described.

When a ringing signal is sent from the telephone line, it is detected by both the incoming call detection section 11 and the answering machine M50. When the Nth (<M) ringing signal is thus generated, the telephone answering machine 50 responds to it. That is, the answering machine 5A 50 plays back the recording tape, sends the playback signal to the telephone line, and records the audio signal sent from the telephone line onto the tape. When the caller hangs up the telephone and disconnects the telephone line, a change in voltage on the telephone line is detected by the call detection circuit in the answering machine 50, and the answering machine 50 stops operating. In this case, the capacitor 17 prevents the influence of the voltage change on the telephone port wAL from being transmitted to the DTMF receiving section 13.

By the way, when the answering machine 50 is in operation, when the caller inputs a specific code signal (for example, a DTMF signal by pressing button 114 TI three times) to activate the telephone control device, the code signal is transmitted through the telephone port IIL. , and a capacitor 17° transformer 19. The signal is transmitted to the DTMF receiver 13 via the normally closed side of the relay contact 15b. The DTMF receiving section 13 receives the sent code signal as a switching signal, and supplies an activation signal to the microprocessor 10. The microprocessor 10 excites the relay 15 in response to the activation signal, closes the telephone line by turning on the contact 15a, and executes the telephone control operation described above. In this case, the voltage change on the telephone line due to the turning on of the contact 15a causes the answering machine 5 to
0 is detected by the call detection circuit, and the operation of the telephone answering machine 50 is stopped.

In this way, when both the out-of-home set switch 34 and the out-of-home set switch of the telephone answering machine 50 are on, the answering machine 50 always responds to the ringing signal first, and the answering machine 50 If a specific signal is input from the telephone line during answering, it is taken in as a switching signal and the telephone control operation is started. It can be used in various ways. Moreover, since the configuration is simple, just adding a circuit including a relay contact 15b, a capacitor 17, and a diode 23 to the DTMF receiving section 13, no cost problems arise.

Further, when the out-of-home set switch 34 is off and the out-of-home set switch of the answering machine 50 is on, normal answering machine operation is performed.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without changing the gist.

[Effects of the Invention] As described above, according to the present invention, when an answering machine that responds to a specific number of ring signals is connected to the same telephone line, and a specific signal is input while the answering machine is responding. A switching signal receiving section is provided which detects from the telephone line that the telephone line has been switched and issues an activation signal, and a control means is provided which starts the telephone control operation in response to the activation signal from the switching signal receiving section. It is possible to provide an excellent telephone control device that can be used on telephone lines.
