Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to an automatic dialing device for telephone or other subscriber communication systems, and more particularly to an automatic dialing device that can be separated into an operation section and a main device section.

[Background of the invention]

An automatic dialing device is a device that stores the telephone number of the other subscriber in advance and automatically dials a call by pressing a button. Conventionally, the stored telephone number data is unique to the device. , this data cannot be used commonly by other automatic dialing devices. Therefore, the present inventor constructed an automatic dialing device with a main unit that is connected to a telephone line and a telephone set, and an operating unit that is detachable from the main unit, and records telephone number data on the operating unit.
, I devised a device that would allow this to happen. According to this device, the operating section and the main unit can be separated, so when you go out, you can take the operating section with you and connect it to the same type of main unit installed outside. Automatic dialing can be made from that location using a pre-registered phone number.

However, with such a device, there is no problem if the main unit to which the control panel is connected is within the same area code, but if it is in an area with a different area code, the connection as described above will not occur. If you try to make a dial call using this function, you may not be able to make a dial call in some areas. For this reason, it is necessary to distinguish between subscribers who can make dial calls and those who cannot, and to distinguish between them, it is necessary to check the area code of the subscriber making dial calls, which is very complicated. , there are 10 advantages of separating the operation section.

[Purpose of the invention]

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the automatic dialing device is divided into a main unit and an operating section, and the operating section is carried and replaced, so that a pre-registered telephone number can be used on the go. To provide an automatic dialing device which can be used in any country and which does not handle differently depending on whether the area code is different or different.

[Key points of the invention]

The present invention has a main unit that is connected to a telephone line and a telephone set, and an operation unit that can be easily removed from the main unit, and the main unit stores the area code of the area where it is installed. a first memory for storing a telephone number; and a dialing circuit for transmitting a dialing signal to a telephone line; a second memory for storing a telephone number in the operation section; The number stored in the second memory is compared with the first area code of the telephone numbers read from the second memory, and if they match, the area code is omitted and the call is made by dialing. The present invention is characterized by comprising a control section for controlling.

[Explanation based on examples]

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram of an apparatus according to an embodiment of the present invention.

In FIG. 1, this automatic dialing device consists of a main unit 1 and an operating unit 2 which is detachably connected to the main unit 1 via a connector 16.

The main unit 1 can be connected to a telephone line terminal 3 and a telephone 4, and the telephone line terminal 3 is connected to a switching circuit 6 of the main unit 1.

The switching circuit 6 is a circuit that switches the telephone line terminal 3 to the telephone 4 side or the dialing circuit 5 side, and one pole is connected to an off-hook detection circuit 7 that detects when the telephone 4 is off-hook.
The other pole is connected to a dialing circuit 5 and to a speaker 9 via an amplifier 8.

In addition to the above, the main unit 1 also includes a memo 1, a subscriber switch group 15, and the like.

The operation section 2 includes a control section 10, and a telephone number memory section 12 for storing telephone numbers, a display section 13, a function switch section 14 for operating dialing, etc. are connected to the control section 1o. The control unit 10 is also connected to the dial transmission circuit 5, switching circuit 6, off-hook detection circuit 7, and memory 11 of the main unit l through the connector 16, respectively.

The function switch group 14, as shown in FIG. Connecting.

The operating section 2 is connected to the main device section 1 through a connector 16, and has a structure that allows for easy removal and portability.

The operation of the device configured in this way will be described next.

First, the operation of storing telephone numbers will be explained.

When the record switch 19 is pressed, the control unit 10 detects this and puts the device into a storage state. Next, subscriber switch group 1
When 5 is pressed, the control section 10 detects this and selects the corresponding memory in the telephone number memory section 12, and at the same time, the previously stored telephone number is erased, making it possible to newly store the telephone number. Also, at this time, the switch number input by the subscriber switch group 15 is displayed on the display section 13. While these operations are being performed, subscriber switch group 1
Data such as switch number 5 is temporarily stored in the control unit 10.

Next, press the number switch 20 in the order of the phone number. Through this operation, the control section 10 identifies this number, writes this telephone number into the corresponding memory of the previously selected telephone number memory section 12, and displays this telephone number on the display section 13 one after another. After writing the telephone number, press the off switch 18. When remembering this phone number,
Even if you are a subscriber with the same area code as the area where this device is installed, remember all the area codes.

On the other hand, a specific subscriber switch 1 of the subscriber switch group 15
5a corresponds to the memory section 11 of the main unit 1, and data such as the switch number of the subscriber switch 15a is stored in the memory section 11 by the same storage operation as described above. Here, the memory unit 11 stores the area code IJ of the area where the main device 1 is installed.

Next, the dialing operation will be explained.

When the call switch 17 is pressed, the control unit IO detects this and activates the switching circuit 6. As a result, the line from the line terminal 3 is turned off, and the line from the detection circuit 7 side to the dial transmission circuit 5 is turned off.
and the dialing circuit 5 closes the connection.

With this connection, the dial tone from line terminal 3 is transmitted to amplifier 8.
The signal is amplified by the speaker 9, amplified by the speaker 9, and used as a monitor.

Next, press the subscriber switch 15 corresponding to the subscriber you want to call. Phone number memory 1 supported by this operation
The telephone number No. 2 is read out by the control unit 10. The data corresponding to the read telephone number is converted into a dial signal by the dial transmission circuit 5 via the control unit 10,
It passes through the switching circuit 6 and is sent to the line terminal 3. When the telephone numbers are sequentially read out, converted into dial signals and sent out, the ringing tone from the line through the line terminal 3 is amplified by the switching circuit 6 and the amplifier 8 and amplified by the speaker 9 so that it can be heard.

When the other party answers, the voice of the other party can be heard from the speaker 9. When the handset of the telephone 4 is lifted, the off-hook detection circuit 7 is activated, and the control unit 10 switches the line of the switching circuit 6 to the off-hook detection circuit 7 and the telephone 4 side, allowing a call to be made using the handset.

Next, the dialing operation, which is a feature of the present invention, will be explained. - When dialing as described above, the part corresponding to the area code of the telephone number read from the telephone number memory unit 12 is checked by the control unit 10 against the area code in the memory unit 11 of the main device unit 1. . If the matching results match, the control unit! When data is sent to the dial transmission circuit 5 via 0, the number excluding the 1 part corresponding to the area code number is sent. As a result, the dial signal excluding the area code is sent from the dialing circuit 5 to the line terminal 3 via the switching circuit 6.

Therefore, if you take this operating section 3 to an area with a different area code and replace it with the operating section of the main unit 1 installed there to make a dial call, the memory section 11 of the main unit 1 Only the subscriber's phone number that matches the area code of the subscriber will be dialed, with the area code removed.

As explained above, even if the operating unit is taken to areas with various area codes and exchanged there to make dial calls, accurate dial calls can always be made automatically.

It should be noted that the present invention can also be applied to private branch exchange equipment such as PBX, and in that case, the above-mentioned area code number also includes signals that supplement the outside line calling signal, such as the 0 calling signal. .

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to remove the operation unit from the automatic dialing device and take it to an area with a different area code to make a dial call. Data can be commonly used for any automatic dialing device. Moreover, even when exchanging the operating unit in an area with a different area code and dialing to a subscriber in that area, the area code of the registered subscriber's telephone number is automatically removed. Since you can make a normal dial call, there is no need to check the area code of the other subscriber each time, and there is no need to worry about making a mistake.
Operation becomes extremely easy.
