Here, the coupling relationship between the outer case 1 and the transmission switch 2 is, as shown in the broken sectional view of FIG. 3, the outer case 1 has a spring action by a spring 48 with a base 47 fixing the transmission switch 2 as a base. Is installed as. When the external case 1 is pressed here, the convex portion forming a part of the external case 1 is pressed down, the push button of the transmission switch 2 is pressed, and the transmission switch 2 is turned on.

The wireless receiver 32 includes a receiving antenna 20 and a receiving antenna.

And a reception display 26 for displaying the reception, and a reception display driver 25 for driving the reception display 26.

Although the calling signal generator 5 and the identification signal generator 10 are provided for calling the partner station in the above-described configuration, the role of the identification signal generator 10 is that of the partner having the identification signal detecting function of the own station. The call signal generator 5 is provided to send a local identification signal to the station to be captured and hold the line with the partner station until the call is completed. The ringing signal generator 5 is for ringing the ringing tone generator of the partner station, and the call is completed. It stops together with (completion of operation of the first timer 4 described later).

First, the wireless transmission unit 31 will be described.

The calling signal is transmitted as follows. The outer case 1 is attached to the base of the case so as to act as a spring,
Only while the outer case 1 is being pressed, the transmission switch 2 interlocking with the outer case 1 is turned on. First, when the outer case 1 is pressed, the transmission switch 2 is turned on, and the time detector 3 detects this time and starts counting the time. A fixed time t
_{After 1} (0.2 to 0.5 seconds) has passed, the time detector 3 sends a first control signal to the first timer 4 to activate it. Upon activation, the first timer 4 sends the first control signal to the ringing signal generator 5 to start sending out the ringing signal. That is, the first
When the timer 4 is activated almost simultaneously with the pressing of the outer case 1, the pressing of the outer case 1 may be stopped and the pressing may be instantaneous. On the other hand, the first timer 4 sends a second control signal to the ringing signal generator 5 to stop the ringing signal when a predetermined time (for example, about 5 to 10 seconds) has been reached from the start. During operation of the first timer 4, the call display driver 7 for displaying that the call is being made,
The call indicator 8 is turned on. On the other hand, during the operation of the first timer 4 (for example, for about 5 to 10 seconds described above), the output signal thereof operates the identification signal generator 10 via the OR gate 9 and the transmitter 11 as well. Therefore, the calling signal and the identification signal described above are combined by the adder 6 and input to the transmitter 11 and transmitted from the transmitting antenna 12 as a transmission radio wave.

The audio signal is transmitted as follows. Outer case 1
When the time during which the transmission switch 2 is continuously pressed reaches a predetermined time t ₂ (for example, about 3 seconds), the time detector 3 that continuously counts the ON time of the transmission switch 2 is controlled by the second control. A signal is sent to the second timer 13 to activate it. Second timer 13
The operation of the first timer 4 is stopped (the signal line for this stop is not shown) and the sending of the calling signal is stopped at the same time that the output of the second timer 13 is passed through the OR gate 9. The identification signal generator 10 and the transmitter 11 are controlled and continuously operated. On the other hand, the output of the second timer 13 turns on the audio input switch 6 and transmits the audio signals of the microphones 17 and 18 mounted around the left and right ears to the transmitter 11 via the adders 19 and 6. It enables the transmission of voice information. The second
While the timer 13 is operating, the transmission display unit 15 is turned on via the transmission display driver 14 in order to display that the transmission is in progress.

Next, the wireless receiver 32 will be described. Receiving antenna 20
The signal received at is input to the receiver 21. The demodulated output of the receiver 21 is input to an identification signal detector 22, a ringing signal detector 23 and a separator 24 which separates only a voice signal. First, the identification signal detector 22 detects the identification signal from the partner radio device and turns on the reception display 26 through the reception display driver 25.
At the same time, the audio output switch 27 is set to the connected state. That is, the communication line is maintained as long as the identification signal is transmitted from the partner station and is received by the own station.

On the other hand, the ringing signal detector 23 detects the ringing signal from the partner radio device, operates the ringing tone generator 28, and outputs this ringing tone signal output through the adder 29 and the voice output switch 27 to the speaker 30.
Output as a ringtone. Further, the voice signal is separated by the separator 24 which blocks the above-mentioned identification signal and ringing tone signal, and is output from the speaker 30 through the adder 29 and the voice output switch 27. When the identification signal is no longer detected, the voice output switch 27 is turned off, but at this time, even if the reception output of the radio wave is obtained, it is determined that the signal should be received by another wireless device, and no ringing sound or voice is output. . As described above, the operation as the wireless device only pushes the outer case, but the wireless device having the function of a normal portable wireless device can be realized.

FIG. 2 is an external view of an embodiment of the present invention. The two antennas 41 and 42 are antennas for transmitting and receiving radio waves, but they do not give a mechanical image and are natural. It is desirable that the antenna be attached to a protrusion that does not affect the transmission / reception efficiency of radio waves when the outer case of the device is pushed by hand. Therefore, for example, it is possible to prepare for the shape of the ears 43, 44 and the like. In the embodiment of the present invention, a speaker is provided at the mouth position 46 and a microphone is provided at the ear positions 43 and 44 so as to correspond to the intuition of human beings.
However, the position is not necessarily limited as long as a sufficient volume can be obtained.

In the present embodiment, the configuration in which the first and second timers 4 and 13 are provided to send only the calling signal and both the calling signal and the voice signal has been described, but the time detector 5, and It is also possible to adopt a press talk system in which all the above timers are not provided, or a system in which only the second timer 131 is used for a fixed time transmission mode.

[Effect of device]

As described above, according to the present invention, there is no need to perform a troublesome operation such as searching for a button to send a calling signal without giving a mechanical feeling like a conventional wireless device.
There is an effect that it is possible to provide a wireless device that is easy to handle for housewives and sick people at home.
