Abstract

PURPOSE:To install a telephone set accessory to each home, by combining skilfully an automatic dial informing device and a telephone automatic response device when an emergency takes place. CONSTITUTION:In using the accessory as an automatic alarming device for the emergency, when a sensor 1 is set on, a terminal 1 of an NAND gate G-1 goes to H. Since a terminal 2 of the G-1 is H with the Q of an FF-3, a loop with the main body and a transmitting station (not shown) is formed via a contact y1-1 and a line transformer LT. An exchange calls out a called party through abbreviated dialing 103 in 3-digit reproduced from a tape after stable running. Since the tape keeps running even during this call, when the called party hooks off in response to the call, a part of the latter half message is listened to by the called party, allowing to inform the energency telephone call.

Description

[Detailed Description of the Invention] In an accessory device for a telephone, there is an automatic notification device that automatically dials and notifies a center or the relevant location in the event of an emergency, such as theft or sudden illness of an elderly person. There has been a desire in the past for a simple device that can be used in any so-called automatic telephone answering device that automatically answers an incoming call. However, conventionally, combining two of these independent devices requires complicated equipment, and automatic emergency notification devices are required to be used once a year after installation.
In order to ensure stable operation even once every few years or even once every few years, there is a drawback in that it is necessary to use a large number of detection devices, etc., and when the power is cut off, the We had to worry about it not working, and it was expensive and complicated, and we didn't have the appropriate equipment.

In view of the above-mentioned conventional situation, the present application skillfully combines an automatic dial notification device and an automatic telephone answering device in the event of an emergency situation, and makes it possible to install this as a telephone accessory device in each home. It is something that

The structure and operation of the present application will be explained in detail below.

FIG. 1 illustrates the recording state of the recording tape 100, and 101 is a conductive foil attached to the starting point of the tape;
102 is a message recorded in the first half of the tape, such as ``This is Hashimoto Corporation, but the person in charge is away.'' is prerecorded. Also 103
is speed dial recorded via touchtone, 10
4 is the second half of the message, for example, ``The answering machine has recorded your request, and I will give you a call.When you hear the beeping sound, please tell me your request.'' Further, 105 is a beep tone, and while this is being reproduced, the recording device is driven as described later. Further, 106 is the end of the tape, and since an endless tape is used in this embodiment, the end is the same as the above-mentioned starting point, but this is not limited to an endless tape, and even when the tape is rewound. Because all you have to do is 2
You may also use a reel of cassette tape.

On the other hand, in Fig. 2, Ll and R2 are telephone lines, NE and cd
s is a photocoupler for detecting a calling signal composed of neon and a photoreceptor, G-1 is a Nant gate, and 1 is a sensor that is turned on due to theft, for example, and this turns on to short-circuit both ends of the above-mentioned -CDS. . ′-! , g is a delay circuit that outputs L level after the above call signal rings 1 to 3 times, FF-1 is a 7-lip front knob for driving loop relay Y-1, and FF-2 is for driving motor M. Flip-flop 3 is a safety timer, Fl-, which outputs the LV level when the tape 100 causes a tape error.
3 is a flip-flop which is set by the output of the safety timer. Moreover, the husband is a reset button for resetting the above-mentioned FF-3, 5, 6 and 7 are amplifying circuits, and 8 is a rectifying and smoothing circuit.

Further, a circuit composed of a transistor TR-3, resistors R8 and R9, a capacitor C2, and a diode D1 is a beep tone detection circuit for detecting the beep tone 105 described above. Further, 1 is a Schmitt circuit, and Y-2 is a relay for recording the caller's incoming message, which is turned on while the above-mentioned beep tone is being played (the recording circuit is not shown).

At the same time, the voice of the developer caller whose relay Y-2 is turned on can be amplified by the speaker SP.

First, a case will be described in which the device described above is used as an automatic notification device in the event of an emergency situation.

When the power is turned on to this device, the set terminal S of flip-flop FF-2 is charged by the charging current of capacitor C1.
Instantly, I set FF-2. So FF-2
Q becomes L, and the motor M is driven via the resistor R5 and the transistor TR-2, and the tape 100 is driven to locate the beginning. When the cueing is completed, the conductor foil 101 and the electrode CP
Since the FF-2 is reset by contact with the FF-2, the running of the tape is canceled. If the conductive foil 101 and the electrode CP are in contact with each other when the power is turned on as described above, the tape will not run and will immediately enter a standby state.

If sensor 1 is turned on in the above state, Nando Game)G
-1 terminal l is pulled up to H level. Since the terminal 2 of G-1 is H due to the Q of FF-3, the terminal 3 of G-1 becomes L, and the flip-flop FF-1 is set via the delay circuit 2, for example, after 1 second, so the FF -1 Q is L
Since the relay Y-1 is kept in the operating state through the resistor R3 and the transistor TR-1, its contact yl-1
, a loop is formed between the device side and a transmitting station (not shown) via line transformers LT. At the same time, Fl-2 is set via the resistor R4, so the tape 100 is driven via the motor M as described above. Therefore, the tape is played back from the starting point, and the played sound is transmitted through the recording/reproducing head RPH, the amplifying circuit 5, the contact y2-1, the amplifying circuit 5, and the line transformer L.
The signal is sent to the originating station from terminals L1 and L2 via T.

The message 102 in the first half mentioned above is sent out first, and although this message is used as an answering machine, it does not have any effect on the exchange at the originating station, and does not affect the tape running. The exchange functions to call the called party by means of the three-digit abbreviated dial 103 that is reproduced after the number has stabilized. The tape continues to run even during this call, so when the called party goes off-hook in response to the call, he or she can hear part of the latter half of the message and thereby know that the call is an emergency call. Subsequently, the beep tone 105 is reproduced, but the signal is detected by a beep tone detection circuit composed of a transistor TR-3 via an amplification circuit (2) and a rectification/smoothing circuit (3). 9
, resistor R11,) holds relay Y-2 in operation via run sister TR-4. Therefore, the contact point y2-1.
By switching y2-2, the voice of the called party coming through the line transformer LT is amplified by the amplification circuit 6 and a message of encouragement is sent to the speaker SP. If the installation location is an office or the like and there is an emergency due to theft, the amplified voice of the called party can be used to scare away the thief.

The above tape 10075 is wrapped around the knee and the conductor foil 101 and electrode CP
When it comes in contact with FF-2 through reset terminal R(1)
FF-1 is reset by the Q output of FF-2, and the device returns to the standby state. However, if sensor 1 continues to be on, the FF-1 and FF-2 cent terminals are reset. Since the L-level t-node human power continues, the operation will continue without returning to the standby state. Therefore, in this case, the safety timer 3 will continue to operate, and when the timer 3 times out after 2 minutes, which is more than one revolution of the tape 100, its output will cause the safety timer's 7 lip-flop FF-3 is set, FF-
The Q output of FF-2 resets FF-2 via the center terminal R(2), further resets FF-1 via the Q output of FF-2, and then resets the FF-1 via the Nant gate G-1.
Since the terminal 2 of the sensor is pulled down to the L level, the output of the sensor 1 becomes invalid, and the device is restored. Since this recovery state is locked, someone must press the reset button 4 to release the lock.

Therefore, by turning on this reset button, the above FF-3
At the same time as the beam is set, it is FF via diode D2.
By setting -2, it is possible to retrieve the beginning of the tape that has stopped midway and restore the normal standby state to the normal starting point position.

It should be noted that if the tape 100 is to be used exclusively as an automatic reporting device in the event of an emergency situation, it is not necessary to pre-record a dedicated message on the tape 100.

Next, the case where this device is used as a general T-talk automatic response device will be explained.

When a call signal enters terminals Ll and L2, terminal 1 of Nantes gate G-1 becomes H by the photocoupler NE and cds.
level and the ringing signal is raised to 2~
After ringing three times, FF-1 is set, so as is clear from the above, a loop is formed, the caller and this device enter a conversation state, and the ringing signal stops ringing. At the same time, as described above, FF-2 is set via resistor R4 to drive the tape 100, and first, as described above, the first half of the message 102 is reproduced and sent to the caller. Then speed dial 10
3 is played back, but since they are both in a conversation state, there is no effect, and then the latter half of the message is played back, and then the beep tone 105 is played back. Approximately 1 second at the beginning of this beep tone is sent to the caller, but after this beep tone charges capacitor C2, relay Y-2 is activated while the beep tone is being played. The incoming message of the caller can be amplified by the speaker SP, and at the same time, the other contacts of relay Y-2 (not shown) can drive the recorder to record the incoming message of the caller. . When the taker 00 makes one round and the conductive foil 101 comes into contact with the electrode CP, the apparatus is restored to the standby state as described above, and the above-described operation is repeated every time a call signal is received. Alternatively, since the output of the Schmitt circuit 9 returns to the H level at the end of the beep tone 105, the same function as the electrode CP can be performed via the capacitor C3 and the transistor TR-5, which are indicated by dotted lines.

Next, in this device, the sensor may be turned on as described above, and the device may be in a state without a brim. This often happens when sensors are installed on doors, etc. Because you will become speechless. However, the safety timer device is activated, the call is temporarily disconnected, and the device is in a locked state from now on. The caller then calls the number again, and this time the device is locked, so the phone will not ring. In such a case, the caller will contact the neighbor's house, the nearest police box, or the nearest center, and have someone dispatched. When that person enters the house while the person is away and finds out that the door is indeed open and a burglar has broken in, the person must contact the outside owner (the person). You can also do it. Alternatively, the person in question can also make a phone call.

In this way, the person himself/herself will be the second person to the person who came in.
The user is only asked to press the pushbutton switch 4 as shown in the figure. This is a reset switch with a large sign on it, and you will be asked to press the reset switch to leave. By simply pressing this reset switch, the device returns to its initial incoming call waiting state. In this way, after pressing the reset switch, the device enters the standby state, so the device will operate again after the person leaves the room again. Even if the door is opened again when leaving and sensor 1 is activated, this time it only happens once. After that, if you call from outside to check again, this time it will work as an automatic response device, so you know that the device is fully restored. Also, as mentioned at the beginning, after installing this device, especially the automatic emergency notification device, it will work once or twice a year, or once every few years, so check this. You can check this by dialing from outside.

In other words, when you call this, you can know that the power has been turned on because it normally works as an automatic response device. Also, since a speed dial number is generated after that, it is possible to detect this and, in fact, detect whether this is a correct signal, such as ※○○. By performing such a service at least once a month, it is possible to guarantee the reliability of the overall operation and provide a sense of security.

Also, while testing this device, if the tester says, ``If anyone is there, please answer the phone.''
Since this is amplified, if an elderly person is bedridden or there is someone nearby, they can pick up the phone and talk to each other to relieve their feelings of loneliness and give them a sense of security. Alternatively, if it is installed as an automatic notification device for alarms such as theft, even if the system is activated and a manager or the like happens to come into the house, the above-mentioned loudspeaker "Please answer the phone" will be heard. , the manager can answer the phone and talk to each other, so you can confirm that the manager has arrived, and at the same time say thank you for your hard work, which is extremely convenient for communication with the manager. It is valid.

As a result, functions such as confirming the operation of an automatic notification device in an emergency situation or constantly checking the function can be obtained very easily and naturally. claims a patent within the scope described above.
