DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cordless telephone device, and more particularly to a cordless telephone device that visually or audibly displays the dial operation of a handset to enable operation confirmation.

A cordless telephone has a base unit installed on the telephone side, and one or more portable handsets that are linked to the base unit, and the handsets are responsible for sending dial signals and transmitting voice signals. Install a transmitting and receiving circuit for transmitting and receiving,
The device is equipped with a receiving circuit that receives dial signals and audio signals from the handset and sends them to the telephone line, and a transmitting circuit that transmits audio signals from the telephone and handset to the handset.

That is, a cordless telephone is a device in which the handset drives a predetermined telephone by intervening wireless transmission and reception between the handset and the base, thereby making it possible to talk to other telephones.

However, with such cordless telephones, since the phone is operated while being separated from the phone and connected to other phones, it is necessary to check whether the coordination between the handset and WL device and the communication between the phones is normal. There is.

Conventionally, whether or not a telephone has connected to another telephone in response to an operation of a handset is confirmed by a tone signal sound emitted by a tone dialer in response to a dial operation of the handset. In this case, since the determination is made by listening to the tone signal sound of the handset, it is not possible to determine whether the telephones are actually not connected or whether the base unit is malfunctioning.

An object of the present invention is to provide a cordless telephone device that is capable of determining whether an abnormal state is present in a base unit and a slave unit, based on reception of a confirmation signal from the base unit, as to whether or not the linked operation between the two is operating normally. .

In this invention, a voice synthesis circuit that converts a dial signal from a handset into an identification voice signal is installed in a base unit installed adjacent to a telephone, and the voice signal obtained by this voice synthesis circuit is transmitted to the handset. The present invention is characterized in that the slave unit generates a dial number identification voice in response to the dial operation by the voice signal from the base unit.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

As shown in Figure 1, a cordless telephone has two telephones.
A base unit 4 is installed adjacent to the base unit 4, a handset 6 is installed corresponding to the base unit 4, and the phone 2 and the base unit 4 share a telephone line 8.
connected to.

The handset 6 has a built-in transmitting circuit for transmitting dial signals and audio signals, and a receiving circuit for receiving audio signals from the base unit 4, and has a dial 10 and a microphone 12 on its front surface. , speaker 14, display element 1
6. A transmitting antenna 188 and a receiving antenna 18B are installed.

The base unit 4 also includes a receiving circuit that receives dial signals and audio signals from the handset 6 and sends them to the telephone line 8, and a transmitting circuit that transmits audio signals from other telephones to the handset 6. In addition to being built-in, there is a transmitting antenna 2 on the front part.
0A and a receiving antenna 20B are installed.

As shown in FIG. 2, the base unit 4 is equipped with a transmitting/receiving circuit 22, which receives the transmitted radio waves from the slave TA6 with an antenna 20B, and amplifies the radio waves with a high frequency amplification/frequency change circuit 24. After changing the frequency to a predetermined frequency, the demodulation circuit 26 demodulates the signal into an audio signal. That is, the output of this receiving system is sent from the terminal 28 to the telephone line 8 and is also applied to the speech synthesis control circuit 30, and the control output of this speech synthesis control circuit 30 is given to the speech synthesis circuit 32. This speech synthesis circuit 32 may be constructed of a speech synthesis high-density integrated circuit (LSI).
Its operation is controlled by the dialing signal to generate a dialed number identifying audio signal, such as the number tone.

This audio signal or audio input from the telephone line 8 is applied to a modulation circuit 34 of the receiving and transmitting system. That is, tml! After the transmission signal is frequency-modulated with the audio signal frequency, it is amplified by the high-frequency amplification circuit 36, and the high-frequency output is transmitted from the antenna 2OA to the handset 6.

As shown in FIG. 3, the handset 6 is equipped with a transmitting/receiving circuit 38. In this transmitting/receiving circuit 38, a high frequency signal received by the antenna 18B is amplified by a high frequency amplification/frequency changing circuit 40 and changed to a predetermined frequency. Thereafter, the signal is demodulated into an audio signal by the 1-mode tuning circuit 42. That is, the demodulated output obtained by this receiving system is applied to the speaker 14 and reproduced.

Further, a ballstone dialer 44 and an audio amplifier 46 are installed at the input section of the transmission system. The pulse tone dialer 44 generates pulse tone signals by operating the dial 10, and the audio input from the microphone 12 is amplified by the audio amplifier 46. The pulse tone signal or the audio output of the audio amplifier 46 frequency-modulates a carrier wave in the modulation circuit 48, and the modulated output is amplified in the high-frequency amplification circuit 50 and then transmitted from the transmission antenna 18A to the base unit 4.

In such a configuration, operation confirmation and phone calls will be explained. When connecting this telephone to another telephone, operate the dial 10 of the handset 6 to generate a pulse dial signal from the pulse tone dialer 44, which is sent to the transmitting antenna 1.8A via the modulation circuit 48 and high frequency amplification circuit 50. to the base unit 4.

The handset 6 receives this and transmits the high frequency amplification/frequency change circuit 4.
0 and IM through the demodulation circuit 42, and the demodulated output thereof is reproduced by the speaker 14, so that the operation dial number can be aurally confirmed. In this case, if the number is displayed on a display means such as a liquid crystal display element, the operation number can be visually confirmed.

As shown in the figure, the base unit 4 receives the dial signal sent from the handset 6, converts it into an identification voice, sends it to the handset 6, and receives it at the handset 6 to confirm. ,
The operation of the base unit 4 and the base unit 4 and slave unit 6 depend on the presence or absence of the audio signal.
It is possible to determine whether the state of coordination with the dial is normal or not, and it is also possible to prevent erroneous operation of the dial.

Next, if the dialing operation is normal, the other party's telephone can be called by this dialing operation. In other words, by dial operation,
