DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having a speed dial function.

[0002]

2. Description of the Related Art Some telephones have a speed dial function. In a telephone having this speed dial function, for example, the telephone number "03-
3458-7163 "is registered in advance (actually,"-"is unnecessary, but it is described for convenience; the same applies hereinafter).

[0003] Then, when a call is made, the user goes off-hook. 2. Press the "Speed key". 3. Enter the abbreviated number “02” using the dial keys. Key operation, the phone number "03-345"
8-7163 "is dialed.

Therefore, according to the telephone having the abbreviated dialing function, the dialing operation for a frequent partner or a long telephone number such as a toll-free telephone can be facilitated, and dial errors can be reduced.

[0005]

However, in order to make a call using the speed dial function, as described above, the telephone number "03-3458-7163" of the target party is used.
Must be registered in the telephone in advance. As a matter of course, it is not possible to call a telephone number that has not been registered by speed dial.

[0006] Moreover, the registration is made by the telephone number of the other party,
Both the abbreviated number and the abbreviated number must be entered correctly into the phone according to the prescribed procedure, so if you do not look at the instruction manual, for example, you may not be able to register or incorrect registration may be performed .

Further, even if the number is registered as an abbreviated number, if the number of registered numbers is large, the abbreviated number may be mistaken when calling, and it is necessary to prepare a memo or the like. The present invention is intended to solve such a problem.

[0008]

Here, considering telephones used in ordinary households and the like, the number of telephone parties is not so large. And when the other party of the call is different, the last four digits or the last three digits of the telephone number hardly match. Therefore, the other party can be distinguished by the last four digits or the last three digits of the telephone number.

The present invention pays attention to such a point. For example, at the time of the first call, the telephone number "03-3458-
7163 "is dialed normally. This will cause normal dialing for this phone number,
This telephone number is stored in the memory. For the second and subsequent calls, press the speed key, then
Enter the last four digits of the telephone number "7163". Then, using this “7163” as a keyword, the original telephone number “03-3458-7163” is extracted from the memory, and the extracted telephone number “03-3458-7” is retrieved.
163 "is dialed. It is like that.

According to the present invention, there is provided a memory, an abbreviated key, and a dial key. When a telephone number is input by using the numeric keys of the dial key, a call is made to the telephone of the input telephone number. Process, and the entered telephone number and the entered telephone number
A set of lower 4 digits or lower 3 digits is stored in the memory, and when the abbreviation key and the dial key are operated, the number input by operating the dial key is entered. as a keyword, searches the last four digits to below 3 digits above stored in the memory, by the search, <br/> phone number that is on the last four digits to below 3 digits and set Is retrieved from the memory, and a call is made to the telephone having the retrieved telephone number.

[0011]

Once a call is made, the telephone number is automatically registered in the speed dial, for example, using the last four digits of the telephone number as a shortened number. Therefore, after that, a telephone call can be made only by inputting the last four digits of the telephone number of the other party.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 1 is a telephone line, 11 is NC
U and 12 are communication circuits, 13 is a transmitter, and 14 is a receiver. Then, during a call, a voice signal from the transmitter 13 is sent out to the line 1 through the call circuit 12 and the NCU 11, and a voice signal from the other party is supplied from the line 1 to the receiver 14 through the NCU 11 and the call circuit 12. You. The NCU 11 has a DTMF signal forming circuit, a 4-wire / 2-wire conversion circuit, a hook switch, and the like.

Reference numeral 21 denotes a ringer for receiving a call, 22 denotes a dial key, 23 denotes an auxiliary operation key or switch, 2
Reference numeral 4 denotes an LCD for displaying a telephone number and the like, and reference numeral 30 denotes a microcomputer for controlling the operation of the entire telephone. The microcomputer 30 is connected to means 11, 12, 21 to 24.

Further, the microcomputer 30 has a memory 31 for storing telephone numbers at the time of abbreviated dialing, and has, for example, a routine 60 shown in FIG. 2 for abbreviated dialing processing.

FIG. 4 shows an example of the external appearance of the telephone. An LCD 24 is provided above the dial keys 22. In this example, it is assumed that the shortcut key is the “#” key of the dial keys 22.

<< Standby, incoming call, etc. >> At the time of standby, the microcomputer 30 determines whether the handsets 13 and 14 are off-hook, whether a ringer signal indicating an incoming call is obtained from the line 1, It is monitored for input.

When a ringer signal indicating an incoming call is obtained from the line 1, the ringer 21 is driven to notify the incoming call. Then, when the handsets 13 and 14 are picked up, this is detected by the microcomputer 30, the ringer 21 is stopped, and the communication circuit 12 is connected to the line 1 through the NCU 11. Therefore, a call can be made with the other party thereafter.

Then, if the handsets 13 and 14 are hooked on after the call, the call termination processing is performed, and then the apparatus returns to the standby state.

In the standby mode, when there is an input from the key 23, a process corresponding to the key input, for example, a one-touch dial, is executed, and then the standby mode is set again.

<< Ordinary Call by Dial Key Operation >> This is a case where a call is made to a partner of a telephone number not yet registered in the speed dial. In this case,
Just like a general telephone, the handsets 13 and 14 are picked up and the telephone number of the other party may be dialed. In this case, it is assumed that a call is made to “03-3458-7163”.

That is, when picking up the handsets 13 and 14, this is detected by the microcomputer 30 and the
The process proceeds to step 61 of the routine 60. In this step 61, the communication circuit 12 is connected to the line 1 through the NCU 11, and then in step 62, key input from the dial key 22 is awaited.

In this case, since the call is made by a normal dial key operation, the telephone number "03-3458-7163" of the other party is inputted from the dial key 22.

Then, the process proceeds from step 62 to step 63, in which step 62
It is checked whether the first digit of the key input is a numeric key of the dial key 22.

In this case, since the first digit of the key input at step 62 is a numeric key ("0" key), the process proceeds from step 63 to step 64. Phone number 4 below
The number of digits, the telephone number, and the number of calls to the telephone number are set as one set, and the set is stored in a table format in the memory 31.
Registered in.

In this case, the telephone number "03-3458-7"
163 "for the first time, as shown in FIG. 3, the last four digits of the telephone number"# 7163 ", the telephone number" 03-3458-7163 ", and the number of calls" 1 ".
Are set as a set, and this set is registered in the memory 31. In FIG. 3, “#” before the last four digits is a symbol (code) added at the time of registration, and indicates that the subsequent four digits are abbreviated numbers. That is, hereafter, the last four digits “7163” are replaced with the telephone number “03-34”.
58-7163 ".

Subsequently, the processing of the microcomputer 30 is performed in step 6
The process proceeds from step 4 to step 65, in which display data indicating the telephone number input in step 62 is supplied to the LCD 24, and the telephone number is displayed on the LCD 24. In this case, the telephone number "03-3458-7"
163 "is displayed.

Then, the process proceeds from step 65 to step 66, in which step 62
The dial data of the telephone number entered in
Is supplied to the NCU 11, is converted into, for example, a DTMF signal, and is then sent out to the line 1. Therefore,
This means that the dialing of "03-3458-7163" has been performed, and if the other party answers the telephone, the telephone conversation can be performed as described above.

Also, in this case, even if the other party has not made a call in the past, if the other party makes a call, the lower four digits of the telephone number are added to the telephone number as shown in FIG. This will be registered in the memory 31 as a short number.

<End of Calling> The process of the microcomputer 30 proceeds to step 71 following step 66. In step 71, it is checked whether the handsets 13, 14 are on-hook. , Step 71 is repeated.

Therefore, during a call with the other party, it is monitored in step 71 whether or not the on-hook operation has been performed.

Then, the call ends, and the handsets 13, 14
Is on-hook, this is detected in step 71, and the processing of the microcomputer 30 proceeds from step 71 to step 72, where the data in the memory 31 is sorted. In this case, this sorting is performed in units of one set of the abbreviated number, the telephone number, and the number of calls, such that the set with the highest number of calls is the first.

When this step 72 is completed,
The routine 60 ends, and the system returns to the standby state.

<< Calling by Abbreviated Dialing >> This is a case where a call is originated by the abbreviated dialing function. In this case, pick up the handsets 13 and 14 and then dial key 2
Then, the user presses the "#" key of No. 2 and then inputs the last four digits of the telephone number of the other party from the dial key 22. For example,
As shown in FIG. 3, when abbreviated numbers are registered in the memory 31, when dialing “03-3458-7163”, “# 7163” is input from the dial key 22.

That is, when the handsets 13 and 14 are picked up, the processing of the microcomputer 30 proceeds to step 61. In this step 61, the communication circuit 12 is connected to the line 1 through the NCU 11, and then in step 62, the dial key 22 Wait for input from.

In this case, since the call is made by abbreviated dialing, the dial key 22 is used to input the abbreviated number "#
7163 ".

Then, the process proceeds from step 62 to step 63, in which step 62
It is checked whether the first digit of the key input is a numeric key of the dial key 22.

In this case, since the first digit of the key input in step 62 is not a numeric key, the process proceeds from step 63 to step 81. In step 81, the first key input of step 62 is performed. It is checked whether the digit is the “#” key of the dial key 22.

Then, in this case, since it is the "#" key,
The process proceeds from step 81 to step 82. In this step 82, the abbreviated number in the memory 31 that matches the last four digits of the abbreviated number input in step 62 is searched, and is set as the matched abbreviated number. The phone number is retrieved. In this case, the short number of the memory 31 is searched using “7163” as a keyword, and “7163”
Telephone number "03-3458-716"
3 "is taken out.

When the telephone number is extracted, the processing of the microcomputer 30 proceeds to step 83, and the processing of step 8
In 3, the number of calls of the set of telephone numbers retrieved in step 82 is incremented by “1”, and then the process proceeds to step 65.

Therefore, in step 65, the display data indicating the telephone number extracted in step 82 is
D24, and the telephone number is displayed on the LCD24. In this case, the telephone number “03-3458-716”
3 "is displayed.

Then, the process proceeds from step 65 to step 66. In this step 66, step 82
The dial data of the telephone number taken out in step (1) is supplied to the NCU 11 through the microcomputer 30, converted into a DTMF signal, and sent out to the line 1. Then, when the other party answers the telephone, the call can be made.

Therefore, a call is made by the abbreviated dial function.

In step 81, step 6
If the key input of No. 2 is not the "#" key, the processing of the microcomputer 30 proceeds from step 81 to step 89. In this step 89, the processing corresponding to the key input is executed. Become.

<< Summary >> As described above, according to the present invention, when a normal call is made, the last four digits of the telephone number are registered as abbreviated numbers, and the telephone numbers are registered in the abbreviated dialing memory 31. Therefore, thereafter, it is possible to call the other party by abbreviated dialing simply by dialing the last four digits of the other party's telephone number, that is, without registering the abbreviated dialing.

Moreover, since the registration of the speed dial is automatically executed, there is no need to refer to the instruction manual or perform troublesome key operations every time the registration is performed, and anyone can easily perform the speed dial function. Can be used.

When the number of call destinations is large, the data in the memory 31 may overflow. However, since the data in the memory 31 is sorted in descending order of the number of calls at step 72, the data in the memory 31 When the data overflows, the telephone number of the other party whose number of calls is small is not registered in the speed dial, and even if the number of call destinations is large compared to the capacity of the memory 31, a practical speed dial registration is performed. It can be performed.

<< Other Examples >> In the above description, the lower 4
If the digits (abbreviated numbers) match in the telephone numbers of two or more opponents, in step 63, the corresponding opponent's telephone numbers are selectively displayed by operating the key 23, and the display is performed. What is necessary is just to make it dial to the telephone number made.

Although the last four digits of the telephone number are used as the abbreviated number, the probability that the last three digits of the telephone number match is 1/1000.
The last three digits can be abbreviated numbers. Or lower 4
The digit and the last three digits may be selected by a user using a switch.

[0049]

[0050]

According to the present invention, when a call is made normally, the last four digits of the telephone number are set as the abbreviated number, and the telephone number is registered in the abbreviated dialing memory 31.
After that, just dial the last four digits of the other party's phone number,
That is, it is possible to make a call to the other party by speed dial without registering speed dial.

Furthermore, since the registration of the speed dial is automatically executed, there is no need to refer to the instruction manual or perform a troublesome key operation every time the registration is performed, and anyone can easily perform the speed dial function. Can be used.

When the number of call destinations is large, the data in the memory 31 may overflow. However, since the data in the memory 31 is sorted in descending order of the number of calls in step 72, When the data overflows, the telephone number of the other party whose number of calls is small is not registered in the speed dial, and even if the number of call destinations is large compared to the capacity of the memory 31, a practical speed dial registration is performed. It can be performed.
