In the past, there were many cases where parents were confused because a dumb old man wandered around regardless of the statute of limitations, and as a countermeasure, sensors etc. were used to detect when a dumb old man wandered and forcefully lock entrances and exits 1 to 1. and prevent it,
There was a method to search for the whereabouts of a wandering dumb old man by having the dumb old man carry a radio transmitter and detecting the direction of the emitted radio waves, but the former was a large-scale device that installed automatic doors and was expensive. Due to the price, it was not something that could be installed and used personally. In the latter name, the radius is 4 to 5 K.
Due to conditions such as the power consumption of the wireless transmitter, which requires a service area of 24 hours and a transmission duration of 24 hours, and the power consumption required for constant standby for about half a year, the capacity of the power supply battery becomes large, and It was difficult to make something light and small that could be carried around at all times, and it also required a device to detect wandering, a direction finder, etc., which inevitably led to high prices.

FIG. 3 is an explanatory diagram of the configuration of a single call type device according to an embodiment of the present invention, and FIG. 2 is an explanatory diagram of the configuration of a dual alcohol type device. In Fig. 1, 1 is a power battery, and 2 is a power switch, which cannot be operated by a dull old man.Since this device is designed to be used in all weather conditions, it is equipped with a waterproof mechanism. Due to necessity, a normally closed type reed switch is used as the power switch 2 in this embodiment. M is a magnet, and as shown by the reference arrow, when the device is not in use, a recess for storing the magnet M is provided on the outer surface of the device box near the reed switch 2, and the magnet M is lightly fitted onto the recess to secure the reed switch 2. The structure is such that the power supply can be opened by placing them close together. When using an old man who is dumbfounded, use the recess to remove the makune l-M.
Remove it and close reed switch 2 to use. 3 is a pager, and 4 is a power switching circuit that is closed and self-maintained by the first incoming call signal output from pages 1 to 3, and supplies power to each circuit other than pager 3 to operate each circuit. , the self-holding state is released and the power is turned on when the call signal is received again. Reference numeral 5 denotes a message signal reproducing circuit which reproduces a message signal predetermined by a voice synthesis device C or a voice recording IC.

4D is a power switching circuit, and when the first channel call incoming signal A is input to the ON terminal of 4D, the power supply is closed and self-held, and the second channel call incoming signal B is input.
The configuration is such that when input to the OFF terminal of the 4D, self-holding is canceled and the power supply is opened. The rest of the circuit configuration is similar to that of FIG. 1, and the dashed line 10 indicates one embodiment of the dual alcohol type device. Also, although not shown, the device box, speaker, speaker sound hole, battery case, etc. are equipped with a waterproof mechanism, making it possible to use it in all weather conditions. To attach this device to the body of a dazed old man, it is attached using an arm band and a waist bell.
It must be put on and taken off by a guardian, such as by locking it so that it cannot be easily removed by a dazed elderly person. Also, the device may be made into a pendant type and hung from the neck, but in this case, locking the device around the neck is not gentle and dangerous, so consideration must be given.

Now, when the single-call device 9 according to the embodiment is attached to the arm of the dazed old man using an arm band, the device is locked, and the magnet M is removed from the recess on the outer surface of the device, the device 9 becomes ready to receive the first call signal. If it is inferred that the dumb old man has wandered off without the guardian's knowledge, if the device 9 worn by the dumb old man is called by phone using the pre-registered Pocket 1 to Bell number, Pocket 1 will be called. Hebel 3 receives and outputs the first call incoming signal, which is input to the connected power switching circuit 4, which is closed and self-maintained, and the connected message signal reproducing circuit 5, low frequency amplification Power is supplied to circuit 6 and red flashing light 8, these circuits operate, and the connected speaker 7 emits, for example, "I'm lost. Please help someone nearby. Telephone number 8o1-. Please call 3699 or notify the nearest police station.'' It plays a predetermined message and announces that the person is a dumb old man.

If there are people nearby, they can be expected to report the incident to their parents or police station by phone. The message is repeatedly played until the self-holding of the power switching circuit 4 is released, and when a person who hears the message or a parent who has been contacted by the police station calls Juiso@9 again by phone, The self-holding of the power switching circuit 4 is released by the incoming call signal again, the power supply is opened, reproduction of the message is stopped, and the device 9 is restored and waits to receive the next first call signal. In addition, in the pocket l-bell system, there are occasional incidents of 1 dial, 2 calls, where the phone calls only once, but then receives a second call after a few minutes. When this device 9 is operating and playing messages, if a call radio wave is accidentally sent to the device 9 that is not the intention of the parent, the device 9 will not be able to call again. Sometimes the message playback operation is stopped because it is determined to be an incoming call signal, and parents may not be able to detect this and may be confused. In the dual-alcohol device 10 of the Poe embodiment shown in FIG. 2, even if an accident such as one dial and two calls occurs, it is possible to continue operating without any trouble.

, when the parent calls the second channel by phone and the first channel call incoming signal A is input to the ○N terminal of the power switching circuit 4D, the circuit is closed and self-maintained, and the following occurs. As in the case of the single call type device 9 of the embodiment, when the message is repeatedly played back and the parent who has been contacted by the message calls the second channel by telephone, the second channel call incoming signal B is transmitted to the power switching circuit 4D. When the signal is input to the OFF terminal of the power switching circuit 4D, the self-holding state of the power switching circuit 4D is released and the power is opened, and the device 10 stops and restores the message playback operation and waits to receive the next first channel calling signal. . Even if an accident 1 or so called 1 dial 2 calls occurs during this message playback operation, the 1st channel is dedicated to ON operation, so there will be no change no matter how many call radio waves are sent to that channel. The message will continue to play without any problems.
