Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to an automatic dialing device attached to a telephone.

[Technical background of the invention and its problems] In conventional automatic dialing devices, a pre-registered telephone number is automatically dialed, including the area code, by pressing the corresponding key switch on the abbreviated keyboard. dialed.

However, there are cases where the area code is no longer necessary due to a change in the installation location of the telephone. Also, if only the automatic dialing device of the telephone is made portable, there will be a similar change in whether or not an area code is required.

However, regardless of the location of traditional automatic dialing devices,
Since dialing includes a pre-registered telephone number and area code, there is a drawback that measures must be taken such as re-registering and storing the area code in accordance with the location of the automatic dialing device.

[Purpose of the invention]

The present invention has been made in view of the above, and an object of the present invention is to provide an automatic dialing device that eliminates the above-mentioned drawbacks and eliminates the need to register and store each telephone number again according to the position of the automatic dialing device. do.

[Embodiments of the invention]

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In FIG. 1, numeral 1 is a Keysui-Nochi matrix circuit. The output of the key switch matrix circuit 1 is supplied to a keyboard decoding circuit 2 for decoding, the decoding output of the keyboard decoding circuit 2 is supplied to a memory control circuit 3, and the output of the memory control circuit 3 is used to input a telephone number including an area code. It is configured to access the memory 4, which has been written in advance, and read out data corresponding to the pressed key switch of the key switch matrix circuit 1. Further, the output of the memory control circuit 3 accesses the toll station registration memory 5 in which the toll number of the calling place is stored, and the data is read out.

The upper digits of the data read from the memory 4 and the data read from the toll office registration memory 5 are supplied to a successive approximation circuit 6 to detect a match. On the other hand, data read from the memory 4 is supplied to the oscillation control circuit 7. The output of the comparison circuit 6 is also supplied to the oscillation control circuit 7. The oscillation control circuit 7 receives the coincidence output from the comparison circuit 6 and stops supplying the toll number in the data from the memory 4 to the oscillation circuit 8, and when it does not receive the coincidence output from the comparison circuit 6, the oscillation control circuit 7 All of the data from the oscillator circuit 8 is supplied to the oscillation circuit 8.

The oscillation circuit 8 receives data from the oscillation control circuit 7 and oscillates an appropriate oscillation corresponding to the data, for example, a button signal. This oscillation output is amplified by an amplifier 9 and then drives a speaker 10. The generated sound from the speaker IO is sent to the phone.

In one embodiment of the present invention configured as described above, when the key switch of the key switch matrix circuit 1 is pressed, the output of the key switch matrix circuit 1 is supplied to the keyboard decoding circuit 2, Detect keyswitch. The memory control circuit 3 receives the output of the keyboard decode circuit 1 and 2 and accesses the memory address 40 corresponding to the pressed key switch, and also accesses the toll station registration memory 5. As a result, the data corresponding to the telephone number corresponding to the pressed key switch is read out from the memory 4, and the data corresponding to the telephone number corresponding to the pressed key switch is read out from the memory 4.
The data corresponding to the stored telephone number is read out and successively compared in the comparator circuit 6. Data corresponding to the desired telephone number is output from the Zunawaji memory 4, and the upper part of this data is data corresponding to the area code. Further, the area code registration memory 5 outputs data corresponding to the area code of the location where the telephone is installed. When the area code output from the memory 4 and the area code stored in the area code registration memory 5 match, the comparison circuit 6 detects a match by comparing both data sequentially starting from the most significant digits. Generates detection output. Further, when the area code output from the memory 4 and the area code stored in the area code registration memory 5 are different, the comparison circuit 6 does not generate a match detection output.

When the comparison circuit 6 does not output a match detection output, all the data output from the oscillation control circuit 7 and the memory 4 are supplied to the oscillation circuit 8. As a result, the oscillation circuit 8 outputs an oscillation output corresponding to the telephone number including the area code.

When a match detection output is output from the comparison circuit 6, the data corresponding to the telephone number excluding the area code part in the data output from the oscillation control circuit 7 and the memory 4 is supplied to the oscillation circuit 8. As a result, the oscillation circuit 8 outputs an oscillation output corresponding to the telephone number excluding the area code.

Next, a specific example will be explained. Memory 4 contains the complete information including the area code at the time of registration, for example (A) 0429 49
5111, (b)03 4941111. This registration is performed by pressing the registration instruction switch 11, which instructs registration, and pressing the key switch matrix circuit 1.

Further, the toll code of the location where the automatic dialing device is installed, for example 0429, is also registered in the toll code registration memory 5 in the same manner.

Therefore, when making a telephone call, if a call instruction corresponding to "0429 49 5111" is given in the key switch control circuit 1, the comparator circuit 6 detects that the station number 0429 matches, and oscillates 495111. . Similarly, if an oscillation instruction corresponding to "034941111" is given to the key switch matrix circuit 1, the comparator circuit 6 detects that the station numbers do not match, and "o34941111" is issued.
1111'' oscillation is generated.

In addition, when the station number corresponding to the installation position changes due to a change in the installation position of the automatic dialing device, the stored contents of the toll station registration memory 5 can be changed to data corresponding to the new area code. It is possible to cope with the case of a new installation position. For example, when the installation location is moved to a location corresponding to the location of the area code "03", the data corresponding to "03" will be recorded in the toll station registration memory 5. In the above examples (a) and (b), (a)
oscillates as "0429 49 5111", and oscillates as "494 1111" for (b).

〔Effect of the invention〕

As explained above, according to the present invention, the first memory stores data corresponding to a complete telephone number including the area code, and the data corresponding to the area code of the location where the automatic dialing device is installed. and a comparing means for detecting a match between the data corresponding to the area code in the data read from the first memory in response to a call instruction and the data read from the second memory. , a control means for omitting the matching part in the data read from the first memo and ri based on the detection output of the comparison means when dialing a telephone number, the automatic dialing device can be reused even if the installation location of the automatic dialing device is changed. There is no need to remember the registration of each phone number,
All you have to do is change the registered memory of the station number.
