3 is supplied to the speaker 14.

The dial number registration unit 20 is activated based on a signal from the key switch reading unit 18, and stores an area number and a dial number for designating an area in which the dial number of the speed dial is stored. 1
Storage unit 21). Dial number memory unit 21
Stores a dial number of a speed dial corresponding to an area number in a corresponding storage area according to an instruction from the dial number registration unit 20, and is bidirectionally connected to the dial memory control unit 28.

Further, the dial memory control unit 28
Is a bidirectional connection with a dial changing timer 24, a sending dial number temporary memory 22, and a sending dial number memory 23, and outputs thereof are an MF dial signal generating section 25 and a line opening / closing control section 26. Is given to.

The dial changing timer 24 sends a signal for counting the time limit T for changing the digit of the dial number to the dial memory control section 28. This time limit T determines the time during which the dial number can be changed, and is normally set to 1 to 2 seconds.

The temporary dial number memory for transmission (second storage section) 22 temporarily stores the dial number to be transmitted, and is bidirectionally connected to the dial number memory 23 for transmission. The sending dial number memory (third storage unit) 23 stores the dial number immediately before the actual transmission, and its output is connected to the MF dial signal generating unit 25 and the line opening / closing control unit 26. ing.

The dial memory control unit 28 reads the registered dial number from the dial number memory unit 21 based on the speed dial transmission start signal from the key matrix 10, and sends the dial number temporary memory 22 for transmission.
Temporarily stored in. Then, the dial numbers are read from the sending dial number temporary memory 22 digit by digit, and the voice synthesizing circuit control unit 19 is driven to control the voice synthesizing circuit 12 to generate the synthetic voice corresponding to the read number. , From the speaker 14.

Further, when the dial change timer 24 is activated at the start of transmission of the speed dial, and the operation signal is sent from the change key before the count of the dial change timer 24 reaches the time limit, the change dial is changed. Instead of the number of the corresponding digit of the dial number received from the temporary dial number memory 22 for transmission, the number pressed for the change after that is received as the number of the corresponding digit in the transmission dial number memory 23. The number is stored and actually sent. On the other hand, if the change key is not pressed before the dial changing timer 24 reaches the time limit, the number of the corresponding digit read out from the sending dial number temporary memory 22 at the time when the time limit is reached is the sending dial number. The control is such that it is sent to the memory 23 and stored as the number of the corresponding digit.

Next, the operation of the telephone having the above-mentioned configuration is described in (1)
The normal dial transmission operation and (2) automatic dial or speed dial transmission operation will be described separately. However, FIG. 2 and FIG. 3 show a flowchart at the time of a calling operation by a speed dial.

(1) Normal dial transmission operation.

The ringing signal sent from the telephone exchange through the telephone line 1 is guided to the ringer circuit 2. Upon receiving the ringing signal, the ringer circuit 2 emits a ringer sound or blinks a not-shown indicator lamp to notify the incoming call.

When the user picks up the handset 6 in response to this call, the hook switch 7 operates and the hook switch detector 16 outputs an off-hook detection signal. The line opening / closing control unit 26 operates in response to the hook detection signal, sends an operation signal to the line opening / closing circuit 4, and closes the line opening / closing circuit 4. As a result, the telephone line 1, the bridge circuit 3, the line opening / closing circuit 4 and the speech circuit 5 are connected, and it becomes possible to talk with the outside line by the handset 6.

On the other hand, when the user makes a call, first, when the handset 6 is picked up, the hook switch 7 is activated and the hook switch detector 16 outputs an off-hook detection signal. Along with this, the line opening / closing control unit 26 operates and sends an operation signal to the line opening / closing circuit 4 to close the line opening / closing circuit 4. As a result, the telephone line 1, the bridge circuit 3, the line switching circuit 4 and the speech circuit 5 are connected.

After that, when the key of the key operation section 9 is pressed to input the dial number of the other party, the dial number data is sent from the key matrix 10 to the key switch reading section 18 and read. Then, the number data is sent from the key switch reading unit 18 to the dial memory control unit 28 in the order in which the keys are pressed, and sequentially stored in the sending dial number memory 23.

Subsequently, this dial number memory for transmission 2
The dial numbers stored in 3 are sent to the telephone line 1 in the stored order. At this time, the dial number is sent to the telephone line 1 through either the line opening / closing control unit 26 or the MF dial signal generation unit 25, depending on the selection mode of the dial mode switch 8.

(2) Calling operation by auto dial or speed dial.

Here, only the dialing operation using the speed dial will be described, and the description of the auto dial will be omitted.

In this case, it is necessary to register the dial number of the speed dial beforehand. First, when the registration start key (not shown) of the key operation unit 9 is pressed while the handset 6 is placed, the information from the key matrix 10 is sent to the key switch reading unit 18. The key switch reading unit 18 determines the input content from the number by this key operation.
In this case, because it is the speed dial registration mode,
The key switch reading unit 18 activates the dial number registration unit 20.

After this, an area number for specifying an area for storing the dial number of the speed dial, for example, "0".
When "1" is pressed, the information from the key matrix 10 is read by the key switch reading unit 18 and sent to the dial number registration unit 20.

Thereafter, the dial number guided to the dial number registration section 20 via the key matrix 10 and the key switch reading section 18 is stored in the storage area of the dial number memory section 21 corresponding to the area number.

When the registration end key is pressed after the dial number has been input in this way, the dial number registration unit 20 is passed through the key matrix 10 and the key switch reading unit 18.
A stop signal is sent to the dial number registration unit 20 to complete the registration operation.

As a result, only one dial number of the speed dial is registered, and if the above operation is repeated as necessary, a plurality of dial numbers can be registered as the speed dial.

Next, when making a call using this speed dial, when the handset 6 is taken up, the line switching circuit 4 is closed by off-hook, and the telephone line 1 is connected to the telephone circuits after the bridge circuit 3 ( Step S11).

After this, instead of pressing the other party's number, the transmission start key of the speed dial is pressed, and then the area number, for example, "01" is pressed (step S1).
2). This is the same as pressing the dial number stored in the corresponding area number of the dial number memory unit 21.

Further, the information indicating that the transmission is made by the speed dial is guided from the key matrix 10 to the key switch reading unit 18 and detected, whereby the dial memory control unit 28 is activated.

Next, the pressed area number "01" is read from the key matrix 10 to the key switch reading unit 1.
Then, it is sent to the dial memory control unit 28 via 8. As a result, the dial memory control unit 28
Reads out the dial number stored in the area "01" of the dial number memory unit 21 (step S1).
3) Temporarily store the transmission dial number in the temporary memory 22. After this, the dial memory control unit 28
Controls the sequential reading of dial numbers digit by digit from the sending dial number temporary memory 22 (step S1).
4, 15).

That is, the dial memory control unit 28 first reads the first digit and then clears the dial changing timer 24 to t = 0 (step S16). Further, the dial memory control unit 28 drives the voice synthesis circuit control unit 19 to generate the synthetic voice corresponding to the read number (step S17),
The voice synthesis circuit 12 selects the voice data in the voice data memory 11 for synthesis to output a voice synthesis signal. By transmitting this voice synthesis signal to the speaker 14, a number is emitted as a synthetic voice.

During this time, the dial changing timer 24 is t
Continue counting for 1-2 seconds until = T.

Here, when the user hears the voice dialed number from the speaker 14, if he / she wants to change the number of the heard digit, he / she can press the key of the number to be changed immediately. Whether or not this operation is performed is immediately determined (step S1).
8).

That is, the dial changing timer 24 is t
When the change key is pressed before = T, the information from the key matrix 10 is read by the key switch reading unit 18 (step S25) and guided to the dial memory control unit 28. Dial memory control unit 28
When the information of the changed dial number is received, the number corresponding to the button pressed for change is transmitted as the first digit number, not the first digit number read from the transmission dial number temporary memory 22. Dial number memory 23
Send to. As a result, the sending dial number memory 2
In 3, the number corresponding to the button pressed for change is stored as the first digit number.

On the other hand, in step S18, if the change button is not pressed before the dial change timer 24 reaches t = T, the dial dial temporary memory 22 is read first when t = T. The issued number is sent to and stored in the sending dial number memory 23 as the first digit number (steps S19, S20).

In this way, when the first digit dial number is stored in the sending dial number memory 23, the dial memory control unit 28 subsequently sends the second digit dial number to the sending dial number temporary memory 22. The first digit dial number stored in the transmission dial number memory 23 is transmitted to the telephone line 1 during this period.

In this case, on the basis of the detection result of the dial mode detecting section 17 for detecting the mode, for example, in the case of pulse dialing, the line opening / closing control section 26 which also functions as a dial pulse generating section is driven to transmit the pulse dial. The first digit dialed number is transmitted to the telephone line 1 from the line switching circuit 4 having a built-in circuit (step S
21, 22). However, during this pulse dialing, the speech circuit control unit 27 is also driven to mute the speech circuit 5 and prevent noise from entering from the handset 6.

On the other hand, when the detection result of the dial mode detector 17 is the MF dial, the MF dial signal generator 2
5 is driven. As a result, the speech circuit control unit 27 is driven to control the speech circuit 5,
The first digit dial number stored in the sending dial number memory 23 is sent as an MF dial from the MF dial signal generator 25 to the speech circuit 5 and is sent to the telephone line 1 (steps S21 and S22).

In parallel with this, the dial memory control unit 28 reads the second digit dial number from the sending dial number temporary memory 22 (steps S24, 1).
5). Then, the dial changing timer 24 is set to t = 0 again.
To generate a synthetic voice corresponding to the read number. When such an operation is repeated up to the last digit of the dial number (step S23), the calling operation ends.

According to the present invention, it is possible to confirm the dialed number to be transmitted at the time of calling the speed dial or the auto dial by the synthesized voice and to change only the number of the arbitrary digit at the time of calling. This is convenient when using a part of the registered dial number or when you notice an error at the time of registration, etc.

Further, if the dial number stored in the sending dial number memory 23 can be updated or newly registered in the dial number memory section 21, the convenience is further enhanced.

[0055]

As described above, the dial transmitting device of the telephone according to the present invention displays the dialed number one digit at a time when the speed dial or the automatic dialing is made, and can change the corresponding digit within the time limit by the timer. , If you find an error in the dial number when you make a call or if you want to change only some digits, you do not need to re-enter all the phone numbers for one station before dialing as in the conventional method, and operability is improved. It will be much improved.
