Abstract

(57) [Summary] [Purpose] To facilitate recovery operations when dialing errors occur. [Structure] A telephone with a redial function includes a storage means for storing a dial number entered when making a call, and a hook switch that is pressed within a certain period of time after the dial is input to disconnect and restore the call. means for canceling the last dialed digit when the hook switch is released and the re-dial key is pressed; a call control means for sending out the dial stored in the storage means; It is equipped with a correction validity display means to show that the dial number is valid, and even if a dial number is operated by mistake, if the hook switch is immediately pressed and the re-dial key is pressed, only the last digit is removed and sent.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a telephone with a redial function that makes it easy to recover from dialing errors. It's about machines.

0002

[Conventional technology]

In conventional telephones, the recovery method for dialing errors is, for example, To talk to the number 123-4567, lift the handset and press the hook switch. When I started dialing, I accidentally got the number 123-46. If you accidentally manipulate the dial number, please turn the hook switch once as shown in Figure 3. Press to disconnect and recover the call, then release the hook switch and try again. It was necessary to perform a new dial operation.

0003

[Problem that the idea aims to solve]

With the conventional telephones mentioned above, if you accidentally dial a number, Having to redo the dial operation from the beginning is time consuming and difficult to operate, and the LCD etc. There is a method to correct the misdial while checking it on the display device, but The disadvantage was that the price of the handset was high.

0004 In addition, communication networks of multiple carriers have been constructed, and it is possible to select or When communicating through a network, many dials are required, and operations in the event of a misdialing are difficult. The problem was that the mental pain of starting over was great.

[0005]

[Means to solve the problem]

In order to solve the above-mentioned conventional problems, this invention aims to solve the above-mentioned conventional problems by A storage means for memorizing the number and a hook switch within a certain period of time after dialing. Press to disconnect and recover the call, then release the hook switch and redial. A means for canceling the last dial input digit when a key is pressed, and the dial When a single digit input is canceled, the input dial or dial before the canceled dial is and a call control means that sends a The correction validity display means is also provided.

[0006]

[Effect]

A telephone configured as described above can be used even if the dial number is incorrectly operated. Immediately press the hook switch within the specified time to disconnect and recover the call, and then If you release the lock switch and press the redial key, the previously dialed number will be restored. Only the last digit of the number can be removed and sent. Therefore, try dialing again from the beginning. You can recover from a single-digit dialing error without having to redo the dialing process.

【Example】

Hereinafter, the present invention will be described in detail according to embodiments shown in the drawings. Figure 1 is a reproduction of the present invention. 1 is a block circuit diagram showing an embodiment of a telephone with a dialing function; FIG. Figure 2 shows the dial operation. It is a timing chart showing a method for solving production errors according to the present invention. Figure 3 is a diamond 2 is a timing chart illustrating a conventional method for solving a manual operation error.

[0008] In Figure 1, 1 is a line, 2 is a hook switch, and 3 is an on-hook detection circuit. , 4 is a dial circuit, 5 is a memory circuit, 6 is a controller, 6a is a dial memory control control circuit, 6b is a call control means, 7 is a timer, 8 is a correction validity display means, 9 is a re-dialing 10 is a dial key, 11 and 17 are rectifier circuits, 12 is a 2-wire 4-wire conversion 13 and 15 are amplifier circuits, 14 is a transmitter, 16 is a receiver, and 18 is a ringer circuit. 19 is a speaker (sounder).

[0009] In a telephone with a redial function configured as described above, for example, dial number 1 To talk to 23-4567, press dial key 10 after off-hook. However, I accidentally entered the dial number 123-46. In this case, press hook switch 2 to reset timer 7 and set the time. After starting the count and performing disconnection and recovery at the same time, the count output of timer 7 starts. The LED indicator etc. of the correction validity display means 8 is turned on by force, and the correction validity display means 8 The re-dial key 9 is pressed within a certain period of time that is valid. In this case, the controller The controller 6 activates the dial storage control means 6a and stores the dials stored in the storage circuit 5. Read the number "12346" and remove the last digit "6". canceled da The dial “1234” before the dial is sent to the dial circuit 4 by the call control means 6b. and sent to line 1. The user then dialed “567” from the incorrect number. I want to hear it.

0010 Therefore, the user has to operate the hook switch 2 and the redial key 9. By dialing after the wrong digit, you can make a single digit dialing error. can recover the In addition, the user shall check whether the correction by redialing is valid or not. This can be confirmed by lighting up the LED display or the like of the correction validity display means 8.

[0011] Also, in order to talk to the person with the dial number 123-4567, you can go off-hook. , after dialing "1234567" using dial key 10. , if the call is interrupted due to a conversation or other reason, corrections made using redial key 9 will be invalid. It is confirmed whether or not the correction validity display means 8 is turned off by turning off the LED display or the like. So After that, go off-hook and press the redial key 9. In this case, controller 6 starts the dial storage control means 6a and reads the dial number stored in the storage circuit 5. “1234567” is read and the previously dialed “1234567” is the call control. The control means 6b sends the signal to the dial circuit 4, and then to the line 1. Do it like this Thus, the redial key 9 performs a commonly used redial function.

0012

[Effect of the idea]

The telephone with a redial function in this invention is a telephone with a redial function that uses the dial number input when making a call. A storage means for memorizing the number and a hook switch within a certain period of time after dialing. Press to disconnect and recover the call, then release the hook switch and redial. A means for canceling the last dial input digit when a key is pressed, and a means for storing it in a memory means. A call control means that sends out the dial that is being held and cancels the last dialed digit. Since it is equipped with a correction valid display means to show that the dialed number is valid, If you press the hook switch immediately and press the redial key, Only the last digit can be removed and sent.

[0013] Therefore, you can easily complete the final step without having to restart the dial operation from the beginning. It is possible to recover from a digit dialing error.

[0014] In addition, corrections that indicate whether or not corrections made by re-dialing on an LED display, etc. are valid. The above functions can be realized at low cost simply by adding an effective display means.
