It operates by transmitting to the controller 12. Reference numeral 14 denotes a battery that supplies power to the remote controller 12.

[0008] The controller 2 of the adapter body 1 and the remote controller 12 communicate by radio or infrared. The wireless or infrared communication between the remote controller 12 and the control unit 2 can be switched by automatically determining the communication status. Generally, infrared rays have strong directivity and allow clear calls, but communication becomes impossible if an obstacle is on the optical path of the infrared rays. In the case of wireless communication, communication is not interrupted even if you are in the next room, in the toilet, or on the second floor, but if there is interference from other radio waves, communication failure may easily occur, and noise may occur. It is easy for senior citizens to hear, and because there is a possibility of wiretapping, they basically call using infrared rays, and switch to wireless when they cannot use infrared rays. . This switching is performed by periodically emitting infrared rays for checking from the infrared light emitting device provided on the adapter main body 1 and automatically performing the operation when the infrared light emitted periodically cannot be received by the infrared light receiving device of the remote controller 12. When the remote controller 12 is used, or when the remote controller 12 is used, the infrared light emitting device of the remote controller 12 emits a check infrared ray, and when the adapter main body 1 can receive the light, a light reception signal is transmitted to the remote controller 12. Thus, communication is performed by infrared rays, and if light cannot be received at this time, communication is switched to wireless.

Reference numerals 15a and 15b denote informing means provided on the adapter body 1 or the remote controller 12.
The notifying means 15a and 15b are for notifying the user of an incoming call or off-hook when the other party picks up the receiver, and incorporates a high-brightness lamp, a high-volume bell or a vibrator. And the notification means 15a,
When a lamp is used as the lamp 15b, the notification may be made by the lamp 6 of the adapter body 1 or the lamp 12d of the remote controller 12. Reference numeral 16 denotes an emergency broadcast receiver provided in the adapter body 1.
Is a speaker 5 of the adapter body 1 when an emergency broadcast is performed.
a) The broadcast is automatically performed via the speaker 12b of the remote controller 12. When a call is in progress, an interrupt function provided in the control unit 2 interrupts the telephone voice during the call to make an emergency. The broadcast is notified to the user.

[0010] In such a configuration, an AC power supply adapter 4 is connected to the adapter body 1, and a wired line 3 and a general telephone are connected to terminals of the adapter body 1.
When an incoming call is received in this state, a telephone call is made using a general telephone, or using the hands-free speaker 5a and the microphone 5b of the adapter body 1 or the microphone 12a or the speaker 12b of the remote controller 12. Then, when making a call, the call may be made using a general telephone. However, when suddenly feeling sick or feeling ill, asthma, heart attack, etc., and seeking rescue, the one-touch dial button 7 using the adapter body 1 or the remote controller 12 which is closest to the user,
Using 12c, a person in charge or a nearby collaborator or family doctor can be called for help. At the time of this call, the telephone number of the elderly or severely disabled person who seeks rescue is notified to the other party by the telephone number notification function of the control unit 2, so that even if the voice is muted, the other party can be known. Therefore, measures such as arranging an ambulance can be taken. When an emergency broadcast is performed, the emergency broadcast receiver 16 is notified of the emergency broadcast from the speaker 5a of the adapter body 1 or the speaker 12b of the remote controller 12. When the broadcast of the emergency broadcast receiver 16 is notified from the speaker 12b of the remote controller 12, infrared or wireless communication for communication between the adapter body 1 and the remote controller 12 is used. If the emergency broadcast receiver 16 provided in the adapter body 1 receives an emergency broadcast during a call, the emergency broadcast is interrupted by the interrupt function of the control unit 2 and the emergency broadcast flows from the receiver. .

If the receiver is inadvertently forgotten to hang up after a call or touched the receiver and accidentally removed the receiver and did not notice it, the busy tone based on the off-hook of the receiver during a non-call or the receiver held for a certain period of time By doing so, the line side voltage becomes 0V. This busy tone or 0 volt voltage is
0, that is, it is detected by the tone detector 10a or the line voltage monitor 10b. When the off-hook is detected in this manner, the control unit 2 disconnects the general telephone from the wired line 3. Due to this disconnection, the off-hook busy tone and the 0V voltage from the ordinary telephone are not detected. Then, the on-hook signal output from the control unit 2 causes the control unit 2 to be in a state where it can receive a call.

Therefore, if there is an incoming call, the adapter body 1
Notification means 15a and the remote controller notification means 1
The buzzer or lamp of 5b sounds or blinks, or the vibrator of the notification means 15b of the remote controller 12 vibrates. When the user notices these notification signals, the user picks up the receiver off the ordinary telephone, and the adapter 1 or the remote controller 1
When the call button 2 is pressed, the control unit 2 connects the disconnected ordinary telephone to the wired line 3, so that the call may be continued. At this time, a call may be made using the hands-free speaker 5a and the microphone 5b provided in the adapter body 1 without using the receiver of the general telephone, or the microphone 12a of the remote controller 12 may be used.
And a call may be made using the speaker 12b. During this call, the emergency broadcast receiver 1 provided on the adapter body 1
When the emergency broadcast is received by the control unit 6, the emergency broadcast is interrupted by the interrupt function of the control unit 2 to notify the emergency broadcast via the general telephone, the speaker 5a of the adapter body 1, and the speaker 12b of the remote controller 12. Become. When making a call using the remote controller 12, the adapter main body 1 and the remote controller 12 are connected to each other by infrared or wireless communication to perform communication. The infrared and wireless modes are automatically switched according to the communication status. Switching between infrared rays and wireless communication basically gives priority to infrared rays, and automatically switches to wireless communication when infrared rays cannot be received so that communication is not interrupted.

Another preferred embodiment shown in FIG. 3 is a simplified type which does not supply power to the adapter body 1 from the outside, uses the voltage of the wired line 3 as a power source, and does not use the remote controller 12. This is an adapter, and the operation and effects are the same as those of the preferred embodiment. FIG. 4 shows another electric circuit used in the preferred embodiment of the present invention. The difference from the above-described preferred embodiment is that the pseudo circuit 11 and the tone detecting section 10a are omitted. The reason why the tone detector 10a is omitted is that the tone detector 10a
This is because the off-hook can be sufficiently detected by the circuit voltage monitoring unit 10b alone. The reason why the pseudo circuit 11 is omitted is that the pseudo circuit 11 is used.
If there is an incoming call with the handset forgotten, the call can be made just by picking up the handset and pressing the talk button.If the pseudo circuit 11 is omitted, if there is an incoming call with the handset forgotten, The off-hook receiver must be once hooked up to a general telephone, and then off-hook again to make a call, which complicates the operation, but has the advantage that the number of parts is reduced and the device can be provided at low cost. Will occur.
