Abstract

PURPOSE:To prevent mis-dialing, by sequentially displaying a dialed number at the end of dialing. CONSTITUTION:In switching a selecting switch 12 to the position of a dial key 10 and operating the dial key 10 sequentially, the corresponding numbers are inputted to a controller 6 via the switch 12. The numbers are stored in a memory of the controller 6 and displayed on a digital display device 7. If the numbers displayed on the display 7 are coincident with the telephone number of a called party, a confirming switch 8 is depressed. Then, the content of the memory is transmitted to a transmitter 9, where a frequency signal corresponding to the numbers is generated and transmitted to a line via a manual switching device 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone number confirmation device that can confirm the telephone number of the other party to be called, and its purpose is to display the operated numbers in order when the number insertion on the telephone is completed. To provide a telephone number confirmation device which transmits a number by pressing a confirmation button and prevents calling of an erroneous destination.

The present invention will be explained in detail below using examples. 1st
The figure shows a first embodiment, in which a telephone number confirmation group [B] is provided separately from the existing push-button type telephone A. FIG. 2 is a circuit block diagram of telephone A and telephone number display device B. In telephone A, 1 is a bell that indicates an incoming call, 2 is a group of buttons, 3 is a transmitter, 4 is a receiver, and 5 is a receiver. Each shows a hook switch closed by lifting I4, while telephone number display device B
is provided with a controller 6 including a memory, a digital (numeric) display 7 for displaying the contents of the memory on the controller 6, a confirmation switch 8 for controlling the controller 60, and a confirmation switch 8 for controlling the controller 60. By operating the switch 8, the transmitter 9 receives the contents of the memory and generates a frequency signal, and the signals from the dial key 1° and the voice-to-number converter 11 are selectively input to the controller 6. A selection switch 12 is further provided. The dial key 10 is "o" to r9J [
It consists of *Jr#J keys, and when pressed, a numeric signal corresponding to the pressed number is outputted to the selection switch, and the audio number converter 11 converts the audio input from the microphone 15. It includes a circuit that decodes the signals, and converts the decoded numbers into a numerical signal similar to the above-mentioned numerical signal and outputs it to the selection switch 12. 13 is a manual switch for connecting or disconnecting the output side of the transmitter 9 in parallel to the cord 14 connected to the telephone A.

In the embodiment shown in FIGS. 1 and 2, the existing telephone A can be used in exactly the same manner as before. Telephone number verification device B is enabled to operate by switching the manual switch 113 to the telephone number verification device B side. For example, by switching the selection switch 12 to the dial key 10 side and pressing the dial key 10 to "1". ~ It's your turn to operate in the order of "7"! , numerical signals indicating the numbers "1" to "7" are input to the controller 6 via the selection switch 12. Therefore, the number is stored in the memory in the knee controller 6, and the number is displayed on the digital display fW7. Next, read the number displayed on the digital display 7 and call it out. If it is confirmed that the phone number matches the number of the other party, press the confirmation switch 8, and the current contents of the memory are sent to the transmitter 9, where the corresponding number in the pushbutton group 2 is pressed. Numbers “1” to “7”
A frequency signal that is exactly the same as the frequency signal that is generated when the button "" is pressed is generated, and is sent to the line via the manual switch 13. On the other hand, if you switch the selection key 10 to the side of the voice-to-digit converter 11 and say ``ichi'', ``nii'', etc. into the microphone 15, the voice-to-digit converter 11 will respond with ``1'', Numerical signals ``2''...``7'' are generated and input to the controller 6 via the selection switch 12, and the following is the same as above. In the above, if the numbers displayed on the digital display 1!7 are incorrect, although not particularly shown in the figure, press the power-on switch to clear the memory and perform the operation again.

FIG. 3 shows a second embodiment in which an existing dial-type telephone A' is equipped with a telephone number confirmation device [B'.
Components that are the same as those in the figures are given the same reference numerals.

What is different from FIG. 2 is that the telephone A' is provided with a dial 16, and the telephone number confirmation device B' has a dial pulse transmitter 1117 that generates the same pulse as that generated when the dial 16 is operated. This is the point that it is provided.

FIG. 4 shows a third embodiment in which a telephone number verification device is integrated into a push-button type telephone, and the interior is as shown in FIG. 5. In this figure as well, the same parts as in FIG. 2 are given the same reference numerals. What is different from FIG. 2 is that the frequency signal transmitter 9 corresponding to the transmitter 3 and the poufchet button group 2 is connected to the contact 18a of the confirmation switch 18.
'', connected to internal lines 19 and 20 via 18b,
Another contact 18C of the confirmation switch 18 is connected to the internal line 19.
is inserted, and the outgoing voice I3 is sounded by the voice input section of the voice-to-digit converter 11, and furthermore, the controller 6 receives a detection signal from the dial tone detector 21 that detects the dial tone transmitted when the line is connected, and the display is displayed. The controller 6 is configured to automatically send out the numbers given by the hook switch 5, and furthermore, the controller 6 is configured to control power-on, memory clear, etc. using a signal from the hook switch 5.

In the embodiment shown in FIG. 5, when the handset 4 is removed, the hook switch 5 is closed and the contents of the memory and display are cleared. Therefore, by switching the selection switch 12 to the dial key 10 and operating the dial key, or by switching the selection switch 12 to the voice-to-digit converter 11 side and speaking into the transmitter 3, the controller 6 can be contacted. When a numeric signal is inputted, the digit is stored in the memory in the controller 6 and displayed on the digital display I7. Then, when the switch 18 is pressed, the contacts 18a to 18c close, and the dial tone sent from the station is detected! When 121 is detected, the contents of the memory of the contraler 6 are input to the transmitter 119, and the corresponding 1lkfa signal is generated and transmitted to the line. When the receiver 4 is returned to the telephone after the call, the hook switch 5 is opened and the memory in the controller 6 is cleared.

FIG. 6 shows a fourth embodiment in which a telephone number confirmation device is integrated into a dial type telephone, and in this figure, the same parts as in FIGS. 3 and 5 are designated by the same reference numerals. has been attached. This embodiment is the same as the embodiment shown in FIG. 5, except that the controller 6 generates dial pulses from the dial pulse generator 17.

In the above embodiment, the telephone number is confirmed using the digital display 7, but the telephone number can also be confirmed by voice using the receiver 1B4 or a specially provided speaker.

As described in the several embodiments above, the present invention has the feature that it is possible to confirm a call number that has been operated once.
