The signal is emitted from the DTMF emitting section.

In this telephone device, the DTMF (No. 3) emitted by the automatic dialing device DM is acoustically detected by the DTMF detector 5, and the detected DTMF No. switch 1
and then sent to the telephone line. That is, with the above-described operation, it is possible to make a call to the destination selected from the telephone number registered in the automatic dialing device DM without operating the dial 4 of the telephone device.

Next, a second embodiment will be explained.

The second embodiment is an example implemented in a multi-function telephone such as a so-called button telephone, which itself is controlled by a microprocessor, and the dial signal format of the telephone line is DT.
This can be carried out regardless of whether it is an MF signal format or a DP signal format (a format in which the dial signal is composed of the number of intermittent DC loops of the communication line).

As shown in FIG. 2, like the first embodiment, the second embodiment is also comprised of a telephone main unit and an automatic dialing device DM.

To explain each part of the telephone main unit, 21 is a central control unit (hereinafter referred to as CPU) which collectively controls the telephone main unit.
It's called (T). ), 22 is a line control unit that controls the opening and closing of the telephone line and also controls the transmission of dial signals (dial pulses) when the dial signal format is the DP signal format; 23 is a line control unit that controls the telephone line under the control of the CPU A dial signal generation unit that generates a dial signal to be sent to the line, 2

Also, to explain each part of the automatic dialing device DM, 1.
1 to 15 are the same as the same symbols as in the first embodiment (11 is c p to distinguish it from the CPU (T) of the telephone device)
Let it be U (D). ), 31 is a dial code generation section that generates a dial code corresponding to the telephone number information stored in the temporary storage memory 15, and 32 is a dial code emission section that emits the dial code generated by the dial code generation section.

In each of the above parts, the dial code detection unit 24 of the telephone device, the dial code generation unit 31, and the dial code emission unit 32 of the automatic dialing device DM are respectively connected to the first
This corresponds to the DTMF detection section 5, [ITMi' emission section 17, and (ITMi' emission section 17) of the embodiment.
In the embodiment, the information transmission medium from the automatic dialer DM to the telephone device is not necessarily limited to DTMF signals (however, DTMF signals may also be used), for example, other audible tones or electric conduction signals. The dial code detection section 24, the dial code generation section 31i, and the dial code emission section 32 are configured by appropriate means depending on the medium used. To explain the case where an electromagnetic induction signal is used as an example, the dial code detection section 24 is a receiving coil, the dial code generation section 31 is a modulator that modulates the electromagnetic induction signal with information stored in the memory 14, and the dial code transmission section 32 is each composed of a transmitting coil. Further, in this case, it goes without saying that the dial code is set in correspondence with each dial number.

Furthermore, the structure of the telephone device and the automatic dialing device DM in the second embodiment is such that the medium includes a DTMF signal, etc.
If an audible sound signal is used, it may be the same as in the first embodiment, but if an electromagnetic voice signal is used as in the above example, the hole 104 provided in the mounting surface 102 of the telephone device and the automatic dialing device may be used. The hole 204 provided in the bottom surface 203 of the DM is not required (there is no need to provide each hole).

Next, the operation of the second embodiment will be explained.

As in the case of the first embodiment, when the automatic dialing device DM is attached to the telephone device and the dialing button 201 is pressed after selecting the destination, the dialing button 201 is read out from the memory 14 and stored in the temporary storage memory 15. Based on the information, the dial code corresponding to the destination telephone number is emitted from the dial code emitting unit 32.

The dial code emitted from the automatic dialing device DM in the above manner is detected by the dial code detecting section 2 of the telephone device.
4, and the CPU(T) 21 reads this and controls the dial signal generation section 23 to generate a dial signal corresponding to the dial code. At this time, CPU(T
) 21 determines the dial format set in the dial format setting unit 25, and when the dial format is a DTMF signal format, the dial code () corresponding to the dial code detected by the dial code detection unit 24 in the dial signal generation unit 23 is determined. I
A TIAF signal is generated, and the DTMF signal is sent to the telephone line via the dial signal sending path of the telephone communication network 2 and the line control section 22. When the dial format is a DP signal format, the dial signal generation section 23 generates an intermittent pulse signal corresponding to the dial code, and the line control section 22 controls the DC loop of the communication line by the number of pulses of the intermittent pulse No. 13. A DP signal is sent to the telephone line by intermittent times.

With the above operations, it is possible to make a call to a selected party from the telephone number registered in the automatic dialing device DM without operating the dial 4.

In addition, in the above second embodiment, the dial format is DTM.
It is also possible to fix it to either the F signal format or the DP signal format, and in this case, the dial format determination process in the dial format setting section 25 and CPU(T) 21 is not required.

[Effects of the Invention] As explained above, the present invention includes an automatic dialing device that has a function of registering and storing telephone numbers, which is attached to the main body of the telephone, and the automatic dialing device itself having a function of registering and storing telephone numbers. (A) Since the automatic dial sending function section does not correspond fixedly to the telephone set, it is possible to automatically send a dial signal based on the dial code emitted. You can also make calls using automatic dialing.

(B) By using a large number of automatic dialing devices, the number of registered telephone numbers becomes infinite.

(C) For example, privacy can be protected by using an automatic dialing device for dealing with people.
