CONSTITUTION:A storing part 11 can store plural telephone numbers to respective abbreviated address, and for example, has a memory area to be able to store the figure or the symbol of 40 digits for respective abbreviated addresses. When plural telephone numbers are registered in the storing part 11 and the abbreviated address is inputted by an abbreviated key 10b and a dial key pad 10a, at the time of the calling, the dialling is automatically executed until the incoming call is performed to the idle line wire by only one dial operation. Thus, a dial operation is simplified.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a speed dialing device in a telephone.

(Prior art) Conventionally, a telephone number has been registered corresponding to a two-digit number (abbreviated number), and when a call is made to the owner of this telephone number, dialing can be performed simply by inputting the abbreviated number. There are telephones that have speed dialing devices that can be used to speed up dialing.

This type of device generally includes a dialing circuit that sends a dialing signal corresponding to telephone number data to a telephone line and dials the telephone number, and a storage means that stores registered telephone numbers in a storage area corresponding to each abbreviated number. , When the shortcut operation button is pressed, the manual shortcut number is read from the key input section, the registered telephone number corresponding to the manual shortcut number is retrieved from the storage area, and this is supplied as telephone number data to the dialing circuit for speed dial control. The configuration includes means.

The user stores and registers the telephone number in the storage means in advance. When making a call to that telephone number, by operating the shortcut operation button and key input section and inputting the shortened number corresponding to the telephone number, the control means reads out the telephone number from the storage means and automatically calls the telephone number. It will dial the phone number, so it is very convenient if you register a phone number that you call frequently.

(Problem to be Solved by the Invention) However, depending on the calling party, one person may have many telephone numbers (external lines), and in this case, it is necessary to search for an external line that receives an incoming call, that is, an external line that returns a ringback tone. The speed dial operation must be repeated, and this type of device, which is designed to simplify the dial operation, cannot take full advantage of its advantages.

Furthermore, as just described, when a single person to be registered owns many telephone numbers (external lines), that person alone occupies many abbreviated addresses, causing inconvenience.

The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to provide a speed dial device for telephones that makes dialing operations easier and makes effective use of the speed dial function. It is about providing.

[Structure of the invention]

(Means for Solving the Problem) Therefore, the present invention includes a line disconnection circuit provided to disconnect the telephone line when the telephone line is captured, and a plurality of registered telephone numbers for each abbreviated address. a storage means capable of storing abbreviated address, and when the abbreviation operation button is pressed, reads the input abbreviated number from the key input section, retrieves one registered telephone number stored in the input abbreviated address from the storage means, and stores it as the abbreviated address. a first abbreviated dialing control means for providing telephone number data to the dialing circuit; an undialed registered number detecting means for outputting a registered number detection signal when an undialed registered telephone number is entered at the input abbreviated address;
When the busy tone detection signal and the undialed registration number detection signal are received, the line disconnection circuit is controlled to temporarily disconnect and reacquire the telephone line, and then the information of the undialed registration number is stored from the storage means. A second speed dial control means is provided which extracts one registered number and supplies it to the dialing means as the telephone number data, and when an abbreviated address is input, first the registered telephone number of one of the input abbreviated addresses is dialed. After that, if the call cannot be received, the undialed telephone number will be automatically sent as long as there is an undialed telephone number.

(Function) Therefore, according to the present invention, if the user registers the phone number of the other party who has multiple outside lines in one abbreviated address as much as possible, then when making a call, the user can make only one call. With this dialing operation, the system will automatically dial until an available outside line is received, and it will also be possible to register more phone numbers by using other abbreviated addresses.

(Example) Examples of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is an exchange, 2 is a telephone, and L is a telephone line connecting exchange 1 and telephone 2. In FIG.

3 is a line control circuit including a hook switch 4a, a normally open electronic switch 4b, and a normally closed electronic switch 4c, 5 is a tone detection circuit, 6 is a communication circuit, 7 is a handset, and 8 is a speaker unit. Signals from the telephone line are supplied through a line acquisition switch 3 and a line control circuit 4 to a tone detection circuit 5 and a speech circuit 6, and are also supplied through the speech circuit 6 to a handset 7 or a speaker unit 8.

The line control circuit 3 functions as a line disconnection means, and disconnects the telephone line in response to a hooking control command while the telephone line is captured by the hook switch 4a or the electronic switch 4b. hook switch 4
A is turned on and off by raising and lowering the handset, and in this case, the handset becomes the operating means for generating the line capture command, and the spring biasing the hook switch 4a in the closing direction constitutes the line capture control means. I will do it. The electronic switch 4b is turned on when the on-hook switch is turned on when making a dial call in the on-hook state, under the control of the control unit 12, which will be described later. In this case, the on-hook switch operates the operating means for generating a line capture command. , and the control section 12 constitute a line acquisition control means.

The tone detection circuit 5 identifies whether the tone signal from the telephone line is a ringback tone, busy tone or dial tone, and outputs identification data.

The telephone call circuit 6 connects and disconnects the handset 7 or the speaker unit 8 to and from the telephone line in response to a call control command.

Reference numeral 9 denotes a dial circuit, and this dial circuit 9 sends a dial signal corresponding to telephone number data to the telephone line via the line control circuit 3.

10 is a key input unit including a dial pad 10a and abbreviation key 10b, 11 is a storage unit, and 12 is a control unit.

The storage unit 11 is capable of storing a plurality of telephone numbers for each abbreviated address. For example, each abbreviated address has a storage area that can store 40 digits or symbols, and the abbreviated address "01" is a telephone number r03-123-456.
7J and r0425-89-0123J are stored as shown in FIG. Comma between both phone numbers ",
" is used here as data representing the break between the two.

To do this, for example, the user presses the memory key and then the shortcut key 10b to inform the control unit 12 that a telephone number for speed dialing will now be registered. Then, the control unit 12 enters the registration acceptance mode. Next, tap the dial keypad 10a to input the abbreviated address, which in the above example is "01". Then, press the dial keypad 10a for the phone number, r031234567.
Enter ゜0425890123J. If the telephone has a liquid crystal display or the like, the control unit 12 causes the input numbers to be displayed on the liquid crystal display in sequence. The operator turns on the write key after confirming the correctness of the input by looking at the display. Then, the control unit 12 writes the manually entered data to the abbreviated address [01j, and notifies the end of the process using a liquid crystal display or sound. When registration is complete, press the memory key again. Then, the control unit 12 cancels the registration acceptance mode. This completes the registration.

In addition to controlling this registration, the control unit 12 functions as a first speed dial control means, an undialed registration number detection means, and a second speed dial control means.See FIG. 3 for details of the control below. I will explain as I go along.

First, in the standby state, the electronic switch 4b is off;
The electronic switch 4C is commanded to be on, and the communication circuit 6 is commanded to be on.

Then, when the hook switch is turned on, and when the on-hook switch is pressed and the electronic switch 4b is turned on in response to a command from the control section 12, a dial tone detection signal is input from the tone detection circuit 5. The control unit 12 learns that the telephone line has been captured (
Step Sl). At this time, the call circuit 6 is on and a ringback tone is supplied to the handset 7 or the speaker unit 8, so that the operator can be informed of the line capture through these.

Next, it is determined whether the call is a speed dial call or a manual dial call depending on whether the shortcut key 10b is pressed (
Step S2).

As a result of this determination, if the call is a manual dial call, the telephone number data input from the dial keypad 10a is sent to the dial circuit 9, and dialing is performed by the dial circuit 9 (step 510).

If the result of the determination in step S2 is a speed dial call, the abbreviated address input from the dial keypad 10a is input (step S3). Note that at this time, the telephone call circuit 6 that was turned on in step S1 is turned off.

Next, referring to the storage unit 11, it is determined whether or not the input abbreviated address has a registered telephone number (step S4).

The specific method can be performed depending on whether or not there is numeric data in the first digit of the registered telephone number storage area.

As a result of the determination, if there is no registered telephone number, the telephone call circuit 6 is turned on and a busy tone is supplied to the handset or speaker unit 8 (step 511).
.

Further, as a result of the determination in step S4, if there is a registered telephone number, the first registered telephone number in the input abbreviated address is given to the dial circuit 9 as telephone number data (step S5). That is, according to the example shown in FIG. 2, the numeric data from the first digit "0" to before the comma "," is given to the dialing circuit 9 as telephone number data.

Next, the output of the tone detection circuit 5 is monitored to determine whether the tone signal from the telephone line is a busy tone or a ringback tone (step S6).

As a result of this judgment, if it is a ringback tone,
The telephone circuit 6 is turned on and the ringback tone is sent to the handset 7 or speaker unit 8 for monitoring.

This allows the operator to know that the call has arrived.

Further, if the determination in step S6 is a busy tone, it is determined whether or not there is an undialed registered telephone number by referring to the storage unit 11 and determining whether there is a number after the comma "," (step S7). .

As a result of this judgment, if there is no message, the process moves to step 81, 1 and a busy tone is transmitted to the handset 7 or speaker unit 8.
be monitored by

On the other hand, if there is an undialed registered phone number, a hooking command is given to the line control circuit 3, and the electronic switch 4c is first turned off to disconnect the telephone IL, and then, for example, after 2 seconds, the electronic switch 4c is is turned on to reacquire the telephone line (step S8).

Next, one of the undialed registered telephone numbers of the input abbreviated address is read and the telephone number data is given to the dialing circuit 9 (step S9). As a result, the second registered telephone number is automatically registered without the need for a second speed dial operation.

Thereafter, steps 86 to S9 are repeated until an incoming call is received or as long as there are undialed registered telephone numbers.
When an incoming call is received or there are no more undialed registered phone numbers, the process moves to step Sll and the speed dialing operation is terminated.

Note that steps 83 to S5 perform processing as a first speed dial control means, step S6 performs processing as a busy tone detection means in cooperation with the tone detection circuit 5, and step S7 performs processing as a non-dial registration number detection means. The processing is performed as follows, and the process proceeds to step S8. S9 performs processing as a second speed dial control means.

As described above, according to this embodiment, by registering a plurality of telephone numbers in the storage unit 11 and inputting an abbreviated address using the abbreviated key 10b and dial keypad 10a, only one operation is required. All calls will be automatically dialed until a call is received or the registered phone number is dialed.

〔Effect of the invention〕

As explained above, according to the present invention, if the user registers the phone number of the other party who has multiple outside lines in one abbreviated address as much as possible, then when making a call, the user can dial only one time. The system automatically dials until a call arrives at an available outside line, which has the effect of simplifying dialing operations.

Furthermore, this allows the user to register more telephone numbers of destinations using the free abbreviated addresses, allowing efficient use of the abbreviated dialing function.
