-23369, Special Publication No. 43-25607). In the above-mentioned prior application, when a message is received on an answering machine, a pager center is called, and the person himself/herself becomes aware of this by ringing the pager he/she is carrying, and then directly calls his or her home answering machine and remotely controls it. However, in recent years in the United States and other countries, pager centers have been using radio waves to call the person carrying the pager, and then sending a short message over the radio waves. In many cases, the person in question can read the contents of a very simple message via the pager they carry. Although there are various methods for this, the present application provides a new means that can be used in common with these methods. The purpose of this application is to contact person A (i.e., a person carrying a pager) who should be contacted by the general public.

2-3 is the caller's incoming message for 15 seconds, and 102-2 and 102-4 are intermittent signals sent from this device to the caller every 15 seconds; Suppose that the incoming message was recorded for 30 seconds. Further, 103 is a dial tone input when the telephone line is closed for paging operation, and 104 is a speed dial reproduced by endless tape T-3, which may be two or three digits depending on the country. Further, 105 is a guidance message sent from the center, 106 is a beep tone sent from the center following the guidance message, and 107 is a beep tone sent from the center to the beginning of the receiving tape T-2 by detecting the beep tone. This is the caller's incoming message that is played, and the intermittent signal at 107-2 is the same as the above-mentioned 102-2.
This is what was recorded and played back. This device is composed of the above-mentioned parts, and has the functions described below in detail. First, when there is an incoming call from an unspecified number of callers, the ringing signal is detected by the ringing amplifier 1 ,
The output sets flip-flop FF-1 and keeps relay Y-1 in operation, so that contact _y1-1 closes telephone lines L1 and L2. At the same time, T-1 drive circuit 2 is connected via contact y _1-2 .
is started and the response tape T-1 starts running.
Here, the response message pre-recorded in T-1 is reproduced by the recording/playback head RPH-1, and then sent to the telephone line L via a well-known amplifying circuit (not shown).
1, sent to L2. 1 response tape T-1
When the conductor foil 4 pasted at the starting point comes into contact with the electrode 5 , a NAND gate G-2, a differential circuit 6 ,
Since the flip-flop FF-2 is set via terminals 2 and 3 of the OR gate G-5, the T-2 drive circuit 9 is activated via the transistor TR-3.
Normally feed the receiving tape T-2 in the recording state.
At the same time, the first counter 13 is set to an operating state by the output of FF-2, and starts counting in seconds from 0 seconds using the 1-second clock 12 as a clock input. Here, the first counter is 13 , 0.
When second terminal 0 switches from L to H level, second counter 1 is passed through terminals 1 and 4 of Noah gate G-7.
The clock terminal C of No. 4 becomes H level, the counter counts 1, and the terminal 1 becomes L level. As mentioned above, the recording time of T-2 is 15
It is divided into seconds, and the counter remembers that this is the first 15 seconds of recording. Now, when the recording time of T-2 reaches 15 seconds, the terminal 15 of the first counter 13 becomes L level, and the terminals 1 and 7 of the NOR gate G-6 and the AND gate G
-3 (terminal 1 is H due to FF-5), one pulse of approximately 0.5 seconds is obtained via the differentiating circuit 7, and the beep tone oscillation circuit 8 is further driven via the terminals 2 and 4 of the NOR gate G-4. Therefore, the above-mentioned beep tone for approximately 0.5 seconds is sent to the telephone line via the line transformer LT. This is done in the same way at the 16th and 17th seconds, so the caller can hear the intermittent signal three times (corresponding to 102-2 in FIG. 2). If the caller speaks the matter without hanging up, the T-2's recording time will be extended by an additional 15 seconds, and this will occur at the 17th second mentioned above.
An intermittent signal will be sent at 32 seconds with 15 seconds added, and then one at a time at 33 and 34 seconds. In addition, from the 17th second mentioned above, 2
At the 19th second, terminal 2 of Noah Gate G-7,
4, the count number of the second counter 14 is 2
Therefore, terminal 2 is set to L. Now, when the caller hangs up after hearing the above-mentioned intermittent signal, a high-level pulse generated in the telephone line causes the instantaneous interruption detection circuit 15 to
Transistor TR-1 turns on momentarily and resets the flip-flop FF-1 from NAND gate G-15 through terminals 1 and 3 of OR gate G-1, so relay Y-1 is restored and released from the closed state. . At the same time, the flip-flop FF-2 is reset by the output of G-15, so the T-2 drive circuit 9 is released and the receiving tape T
-2 stops running. Furthermore, the timer 17 is activated from the output of the above G-15 via terminals 1 and 3 of the OR gate G-18, and after about 2 seconds, one negative pulse is output from the differentiating circuit 18 and the flip-flop is activated.
Set FF-3 and FF-4. Here is the above FF
-3 output keeps relay Y-2 in operation, and contact _y2-1 closes telephone lines L1 and L2. At the same time, the rewinding circuit 19 is activated by the output of the FF-4, and a rewinding operation for rewinding the receiving tape T-2 to the starting point of the current cycle is started. The starting point of that cycle is when the above-mentioned call arrives, the output of ringing amplifier 1 causes inverter G-12 and transistor
This is set by resetting the tape counter 10 to "0000" by driving the solenoid SD for a short time via TR-2. Now, as mentioned above, when the telephone line is closed, a dial tone is sent out from the station. This dial tone is detected by the dial tone detection circuit 20 , and further activates the abbreviated dial drive circuit 21 via the AND gate G-16 activated by the Q output of the FF-3.
Start running. As mentioned above, T-3 has a 2-digit or 3-digit speed dial recorded,
This speed dial is reproduced by the recording/reproducing head RPH-3, further amplified by the amplification circuit 23 , and sent to the telephone line. When the center responds through this speed dial, a guidance message (105 in FIG. 2) is sent from the center to the device, but the device does not respond to this message at all. Therefore, there is no problem in using the system even if the guidance message is not sent. Next, a beep tone (106 in Figure 2) is sent from the center. This beep tone is detected by the beep tone detection circuit 24, and flip-flop FF-5 is inverted to the set state when the beep tone ends. Here, when the terminal of FF-5 goes to the L level, flip-flop FF-2 is set via terminals 1 and 3 of OR gate G-5, so the T-2 drive circuit 9 is activated and the receiving tape is turned on as described above. This time, T-2 is sent normally in the playback state. At this time, the receiving tape T-2 will have finished rewinding to the starting point of that round while calling the center, but this means that when T-2 is rewound to the starting point of that round, the tape The counter becomes "0000" and the counter contact 11 opens as shown, so the flip-flop FF is connected via the inverter G-14.
-4 is reset and the rewind circuit 19 is released. Now, as described above, at the same time as the normal feeding of the receiving tape T-2 starts, the first counter 13 also starts counting in seconds from 0 seconds by the output of FF-2, as described above. On the other hand, the second counter 14
In the normal feed described above, the clock input via the clock enable terminal CE is prohibited by the terminal Q (H level) of FF-5, so the count number 2 is held as described above, and the terminal 2 is at the L level. .
Therefore, since G-9 among NAND gates G-8, G-9, and G-10 is activated, when the terminal 32 of the first counter 13 becomes L level, G-9 is activated.
Terminal 3 switches from L to H level. To explain this in FIG. 2, the caller's incoming message 107-1 is played for 15 seconds and sent to the center, and the intermittent signal 107-2 is also played and sent to the center. While this intermittent signal is being played, a similar intermittent signal is sent from the center to this device, and when audio is input to the center after the intermittent signal from the center is interrupted, the center receives the signal. The movement (which is recorded once at the center) is now extended for an additional 15 seconds. Therefore, even while the caller's message 107-3 is being played back for another 15 seconds, a loop is formed between the center and this device, and the playback of this message is completed. When the terminal 32 of the first counter 13 goes to the L level at 32 seconds from the tape start point of that time, the terminal 3 of the NAND gate G-9 goes to the H level, so the flip-flop FF is transferred through the terminals 2 and 4 of the OR gate G-11. -5, FF
-3, FF-2 resets the second counter 14 , and further resets the first counter 13 by resetting FF-2, and stops the running of the receiving tape T-2. The device returns to the standby state, waiting for an incoming call from the caller. On the other hand, the caller's message recorded at the center is sent after a signal tone is sent to the person carrying the pager, so the person carrying the pager can listen to messages from the customer stored on his or her own answering machine. Can be done. In this embodiment, a cassette tape was used as the receiving tape, but it is also possible to use a multi-track tape of 15 seconds per round. In that case, the first track is used for response, the second track is used only for response when the tape is full, the third track is used instead of T-3 in the figure, that is, the recording track of the multi-frequency signal for speed dialing, and the fourth track and the following are used. It can also be used as T-2 in the figure, that is, a truck for receiving messages from general customers. In this way, even if the pager carrier misses a message when the tape is full, the pager carrier can switch to the response-only track by known means when the tape is full. This makes it easy to directly call an answering machine and listen to the call remotely using known means. As mentioned above, the present invention is already applicable to the well-known patent No. 543449.
In addition to the basic functions such as numbers, the pager center can send messages to the pager bearer, and the pager center can send messages from general customers or messages once stored on the answering machine to the pager center. This makes it possible to send a message in a short period of time to a person carrying a pager who has been called by someone, and it adds a new utility to the answering machine, and its effects are great.
