ら制御信号がでるように設定する。FIG. 2 is a block circuit diagram of a main part showing an electrical configuration of one embodiment of the cordless handset 7 of the cordless telephone apparatus according to the present invention. In the present invention, a control channel signal (f1) used between the master unit 2 and the slave unit 7
For example, a weak signal of a low level in the 380 MHZ band is always output from the master unit. Further, when there is an incoming call to the base unit 2 from outside, a ringing tone signal from outside is also transmitted from the base unit 2 to the slave unit 2 as a calling signal (f2). On the slave unit 7 side, the transmitting / receiving antenna 6 ′ is connected to a first bandpass filter 8, and the filter 8 controls the signal of the control channel.
(f1) and the calling signal (f2) are selected. These signals f
1 and f2 are amplified by the high frequency amplifier circuit 9 and
Supplied to A local oscillation signal is supplied from the local oscillation circuit 11 to the mixing circuit 10, a signal whose frequency has been converted to an intermediate frequency from the mixing circuit 10 appears, and the second bandpass filter 12
And the third bandpass filter 13. A signal corresponding to the signal (f1) is extracted from the second bandpass filter 12. This signal is detected by a detection circuit 14 comprising an envelope detector and supplied to a comparison circuit 15, where it is compared whether it is greater than a predetermined value. The predetermined value is determined as follows. That is, for example, based on the value of the detection output appearing in the detection circuit 14 at a position where the master unit 2 and the slave unit 7 are separated by 2 m, when the detection output is larger than this reference value, a control signal is output from the comparison circuit 15. Set to.

出音が鳴ることになる。On the other hand, a ringing tone signal corresponding to the FM-modulated ringing signal (f2) appears in the third bandpass filter 13, and a switching circuit 16 is connected in series with the signal transmission line.
Is connected, and when the control signal appearing in the comparison circuit 15 is larger than a predetermined value, the switching circuit 16 is cut off, and the ringing tone is not supplied to the subsequent ringing tone amplifier 17 so that the ringing from the speaker 18 is performed. No sound comes out.
Accordingly, power consumption of a battery or a rechargeable battery built in the slave unit 7 is suppressed. Further, the master unit 2 and the slave unit 7 are, for example, 4 m
When it is placed away from the remote unit, the switching circuit 16 is turned on by the control signal from the comparison circuit 15, and a ringing tone sounds from the slave unit 7.

を継続するように設定しておく。In the above description, an example has been described in which the weak signal of the control channel signal (f1) is always output from the base unit 2. However, the base unit 2 always needs to continuously transmit a weak radio wave. For example, when there is an incoming call to the base unit 2 from outside, the base unit 2 may transmit the incoming call simultaneously with the incoming call and only for a period until the calling signal (f2) from the base unit 2 disappears. Good. that time,
A delay circuit 19 is connected to the preceding stage of the switching circuit 16, and the delay time is determined before the ringing signal corresponding to the ringing signal (f2) arrives at the switching circuit 16.
The signal corresponding to (f1) is the detection circuit 14 and the comparison circuit 15
The switching circuit 16 is set so as to be controlled to be in the cut-off state by arriving at the switching circuit 16 via. At this time, the switching circuit 16 is set so as to continue the cut-off state slightly longer than the delay time even if the control signal from the comparison circuit 15 is lost.

By detecting the carrier wave of the call radio wave by the detection circuit 14, the ringing tone of the slave unit 7 can be controlled.

とは言うまでもない。FIG. 3 shows a circuit of another embodiment of the present invention using a wide band amplifier circuit. That is, a broadband filter 20 is connected to the antenna 6 ', and a broadband amplifier circuit 21, a detection circuit 14, and a comparison circuit 15 composed of an operational amplifier are connected. In this case, if the white noise falls below a certain level in accordance with the magnitude of the control channel signal (f1), the ringing tone does not sound. In the above description, the embodiment of the cordless telephone having the slave unit has been described, but it goes without saying that the present invention can be similarly applied to a portable radio telephone or the like.

保持することが出来るという効果が得られる。As described above, the cordless communication system of the present invention does not need to ring the handset when the position of the base unit and the handset is very close to each other. Therefore, both the parent device and the child device do not ring and give noise and discomfort, and furthermore, the energy for ringing is eliminated, and the battery and the rechargeable battery built into the child device are eliminated. The advantage is obtained that wasteful consumption can be suppressed and the battery of the slave unit can be held for a long time.
