In the above-mentioned prior application, when a message is received on the answering machine, the pager center is called, and the person himself/herself becomes aware of this by ringing the pager he/she is carrying, and directly calls his/her home answering machine and remotely controls it. In recent years, in the United States and other countries, pager centers have called the person carrying the pager by radio wave, and then broadcast a short message over the radio wave. The person will be sent to the station via the pager he carries.
Many of them are designed to allow you to see the contents of simple messages. 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 that when a general unspecified number of people wish to contact person A (i.e., a person carrying a pager), they call A's telephone number and record a message on their answering machine. This enables the layered device to call the pager center and send the message from the center to A via radio waves.

A second object of the present application is to provide a means for A to directly call the answering machine and read and listen to the messages remotely even if some of the messages are not delivered to A.

The intermittent signal 7-2 is a reproduction of the recorded signal 102-2 mentioned above.

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 ringing amplifier 1, and its output sets flip-flop FF-1 and keeps relay Y-1 in the operating state, so its contact Telephone line L by y1-1
1. Let L2 be in a closed state. At the same time, the T-1 drive circuit winter is activated via the contact y1-2, and the response tape T-1 starts running.

Here, the response message 9, which has been injected into T-1 in advance, is reproduced by the recording/reproducing head RPH-1 and sent to the telephone lines L1 and L2 via a well-known amplification circuit, which is not shown. Ru. When the response tape T-1 goes around once and the conductor foil affixed to the starting point comes into contact with the electrode part, it will turn off (Nando game)G
-2. Since the flip 70 knob FF-2 is set via the terminal 2.3 of the differential circuit 6 and 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 is set to an operating state by the output of the FF-2 and starts counting in seconds from 0 seconds using the clock 12 of about 1 unit as a clock input. This is the first
When the O second terminal O of the counter 13 switches from L to H level, the clock terminal C of the second counter 14 becomes H level via the terminal 1.4 of Noah Game) G-7, and the counter becomes 1 and the terminal 1 becomes L level. This is to store in the counter that the recording time of T-2 is divided into 15 second units as described above, and 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
becomes L level, and one pulse of about 0.5 seconds is obtained through terminal 1.7 of NOR gate G-6, AND gate G-3 (1 terminal becomes H due to the Q of FF-5), and differentiating circuit 7, and then the NOR gate ) Since the beep tone oscillator circuit 8 is driven through the terminal 2.4 of G-4, the beep tone is sent out to the telephone line through the line transformer LT for about 0.5 seconds.

This is done in the same way at the 16th and 17th seconds, so the caller can hear the intermittent signal three times (102 in Figure 2).
-2). If the caller speaks the matter without hanging up, T-2's recording time will be extended by an additional 15 seconds, adding 15 seconds to the 17 seconds mentioned above for 32 seconds and an additional 33 seconds.
One intermittent signal is sent every 34 seconds. In addition, at the 19th second, 2 seconds after the 17th second mentioned above,
The count number of the second counter 14 becomes 2 through the terminal 2.4 of 7, and the terminal 2 becomes L. Now, when the caller hangs up after hearing the above-mentioned intermittent signal, the high-level pulse generated on the telephone line turns on the transistor TR-1 of the instantaneous interruption detection circuit for a moment, and from the Nante gate G-15 to the OR gate G- Since the flip-flop FF-1 is reset through the terminal 1.3 of the relay Y-1, the relay Y-1 is restored and released from the closed state. At the same time, the clip-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, from the output of G-15 above, OR gate G
Start the timer V via terminal 1.3 of -18 and approx.
After a second, one negative pulse is output from the differential circuit A to set flip-flops FF-3 and FF-4. Here, the above FF-3 and the above FF-4 output simultaneously turn the rewind circuit 1.
9 and starts a rewinding operation for rewinding the receiving tape T-2 to the starting point of the current time. The starting point of that cycle is when the inverter G is activated by the output of the ringing amplifier J at the time of the above-mentioned incoming call.
-12, solenoid S via transistor TR-2
By driving D for a short time, the retape counter W is set to r.
This is set by resetting to ooooJ. 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 I/- tone detection circuit and further activates the abbreviated dial drive circuit 21 via the AND gate G-16 activated by the Q output of the FF-3. 3 starts running. As mentioned above, the T-3 has a 2-digit or 3-digit speed dial recorded, and this speed dial is played back by the recording/playback head RPH-3, and is further amplified by the amplification circuit and sent to the telephone line. Sent out. When the center responds with 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 in any way. Therefore, there is no problem in using the system even if the guidance message is not sent. Next, a beep tone (106 in FIG. 2) is sent from the center as a signal. This beep tone is detected by the beep tone detection circuit 24.
13-, and when this beep tone ends, the 7 lip-flop FF-5 is inverted to the set state.

When the terminal 6 of FF-5 goes to L level, it's a game)
Flip-flop FF-2 via terminal 1.3 of G-5
is set, the drive circuit 12 is activated in the same way as described above, and the reception tape T-2 is normally fed this time 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 This is because the counter becomes l'-0000J and the counter contact 11 opens as shown, so the flip-flop FF-4 is reset via the inverter G-14 and the unwinding circuit is released.

Now, as described above, at the same time as the normal feeding of the receiving tape l-2 starts, the first counter 13 also starts counting in seconds from 0 seconds by the same output of <FF-2 as described above.

On the other hand, the second counter 14 is FF-
Since the clock input to the clock signal 14 through the clock enable terminal CF is inhibited by the clock input terminal Q (H level) of the circuit 5, the aforementioned count number 2 is held and the terminal 2 is at the L level. Therefore, among the Nant gates G-8, G-9, and G-10, G-9 is activated, so when the terminal 32 of the first counter 13 becomes L level, the terminal 3 of G-9 changes from L level. Switch to H level. To explain this in Figure 2, the caller's incoming message 107-1 is played for 15 seconds and sent to the center, and the intermittent signal 1.07-2 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. There are 15 more movements (this will be recorded once at the center).
It is now extended to 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. 32 from the tape start point of that episode
When the terminal 32 of the first counter 13 goes to the L level in the second, the terminal 3 of the NAND game) G-9 goes to the H level, so the flip-flops Fl-5, FF- 3. Reset FF-2, the second counter once, and then reset FF', 2 to reset the first counter.
The counter 13 is reset and the running of the receiving tape T-2 is stopped, and the apparatus is restored to a standby state in which it waits for incoming calls from an unspecified number of callers. 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 listens to the message from the customer stored on his or her own answering machine. be able to.

Although a cassette tape is used as the receiving tape in this embodiment, it is also possible to use a multi-track tape with a cycle length of 15 seconds. 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 person carrying the pager misses the message when the tape is full, the pager can be used by switching to the response-only track by known means when the tape is full. The carrier can easily call the answering machine directly and listen to the call remotely using known means.

As described above, the present invention has the basic function of the already known patent No. 543449, and combines it with a service in which the center of the pager conveys messages to the person carrying the pager. This device makes it possible to transmit messages once stored in the answering machine for a short period of time to the pager bearer called from the pager center, and adds a new utility to the answering machine. is a dog.
