Abstract

PURPOSE:To prevent mis-dialing by hearing the dialing by an ear. CONSTITUTION:A telephone number entered by a dial key 8 at dialing is tentatively stored in a dial signal transmission reception section 4, the telephone number entered by a CPU 1 is retrieved as to whether the telephone number is registered in a memory 2. If the entered telephone number is not registered, the CPU 1 uses a voice synthesis section 6 to convert into voice signal the telephone number received by the dial signal transmission reception section 4 and sends the voice signal to a handset 9 via a changeover section 5. If the CPU 1 recognizes it that off-hook is detected by a hook state monitor section 3, the entered telephone number is converted into the dial signal by the transmission reception section 4 and sent to a telephone line 10 via the changeover section 5 and registered in the memory 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone set, and more particularly to a telephone set with a function for preventing erroneous dialing.

[0002]

2. Description of the Related Art Conventionally, a telephone of this type has a structure in which a telephone number input at the time of making a call is displayed on a display to prevent erroneous dialing.

[0003]

The above-mentioned conventional telephone has a structure in which the telephone number input at the time of calling is displayed on the display to prevent erroneous dialing. There is a problem that you have to dial while watching.

[0004]

A telephone according to the present invention registers a holding means for temporarily holding an input telephone number at the time of calling and, if the input telephone number is unregistered, the telephone number. It has registration means and voice conversion means for transmitting the telephone number to the caller by voice when the telephone number input at the time of calling is not registered.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, the telephone of this embodiment receives a dial key 8 for inputting a telephone number and a telephone number input from the dial key 8 for temporary storage and dials if the registered telephone number matches. A dial signal transmitting / receiving unit 4 for converting into a signal and transmitting it, a memory 2 for storing and registering an inputted telephone number, and a handset for converting the telephone number into a voice when the inputted telephone number is not registered. Voice synthesizer 6 for sending to 9 and on-hook / off of handset 9
A hook state monitoring unit 3 for monitoring a hook, and a switching unit for switching between transmitting a dial signal from the dial signal transmitting / receiving unit 4 to the telephone line 10 or transmitting a telephone number from the voice synthesizing unit 6 to the handset 9. 5 and a central control unit (hereinafter referred to as CPU) 1 that controls the entire embodiment via a bus 7.

Next, the operation of this embodiment will be described.

When a telephone number of the other party is input from the dial key 8 at the time of making a call, this telephone number is transmitted to the dial signal transmitting / receiving section 4 and temporarily stored. The CPU 1 searches whether or not the same telephone number as the telephone number transmitted to the dial signal transmitting / receiving unit 4 is registered in the memory 2.

If there is the same telephone number, the CPU 1 detects the off-hook state and converts the telephone number transmitted to the dial signal transmitting / receiving section 4 into a dial signal and sends it to the telephone line 10 via the switching section 5. After that, the switching unit 5 is connected to the handset 9 and the telephone line 10.

If the same telephone number is not found by searching, C
PU1 is connected to the handset 9 via the switching unit 5 from the voice synthesis unit 6.
In response, the telephone number transmitted to the dial signal transmitting / receiving unit 4 is converted into voice and transmitted.

When the calling party goes on-hook, the hook state monitoring section 3 informs the CPU 1 that the call is on-hook, and the CPU 1 abandons the dial number transmitted to the dial signal transmitting / receiving section 4.

If the caller does not go on-hook, the telephone number transmitted to the dial signal transmitting / receiving unit 4 is converted into a dial signal and sent to the telephone line 10 via the switching unit 5,
Further, this telephone number is registered in the memory 2 by the CPU 1.

[0014]

As described above, according to the present invention, the holding means for temporarily holding the input telephone number at the time of calling, and the registration for registering the input telephone number if the input telephone number is not registered. By providing a means and a voice converting means for transmitting the telephone number to the caller by voice when the telephone number input at the time of calling is not registered, the telephone number not registered at the time of calling If you dial, you can check this phone number by voice, and if you dial the registered phone number, you can call it to the calling party without checking the dialing, assuming that it is not a mistaken dialing. There is an effect that it is possible to further prevent malfunctions as compared with the case of checking with.
