Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic telephone answering and recording device having a paging function. [Prior Art] Conventionally, there has been an answering machine having a paging function, for example, as disclosed in Japanese Patent Application No. 44976/1983. However, these methods do not allow the user to distinguish between cases in which the user, i.e., the caller, absolutely has to call the person in question, and cases in which the caller is reluctant to call the person in question. Therefore, there was a practical problem.

[Problem that the invention seeks to solve]

In order to solve the practical inconveniences of the above-mentioned prior art, the present invention pages the caller according to the response term output from the answering machine when the caller makes a call, or
Alternatively, the object is to provide a means for selecting whether to send only a message to the person while paging the person in question.

〔Example〕

Hereinafter, embodiments of the structure and function of the present invention will be described.

In FIG. 1, A is an answering machine, B is a paging device, and L1 and L2 are telephone lines. In the answering machine A, 1 is a ringing circuit for detecting a calling signal;
2 is a first control section, and when the output of the ringing circuit 1 is applied to the input terminal (river), the output terminal (2) is held at the L level and the load relay Y-l is held on, and at the same time A pulse is generated from the output terminal (3) to start the second control section at the next stage. In addition, the input terminal (4) of the first control unit 2
) is a reset terminal. 3 is the second control section, (
5) is the above-mentioned start input terminal, and when a pulse is applied to this, it drives the response tape T-1, and the input terminal (6) drives the response tape T-1. The first beep tone (50 in Figure 2) is detected by the beep tone detection circuit 6, and when its output is applied, the running of the response tape T-1 is stopped and at the same time, the reception tape T-2 is placed in the recording state. When the caller's voice is detected by the voice detection circuit 9 and the output thereof is applied to the input terminal (7), the above-mentioned recording operation is continued. ing. When several seconds pass without any voice being detected from the caller, a pulse is generated from the output terminal (8), which resets the first control section mentioned above, thereby releasing the hold on relay Y-l and Contact yl-
It is designed to release the connection of the telephone line by 1.

Reference numerals 4 and 5 are amplifying circuits for reproducing the response tape T-1, 7 is an amplifying circuit for recording the receiving tape T-2, and 8 is an amplifying circuit for the voice detection circuit.

Next, in paging device B, L'['2 is a line transformer, and the telephone line Ll is used for operations other than the paging operation described later.
, L2 via a capacitor C1, and performs input/output of signals to be described later. Further, 10 is the signal amplification circuit, and 11 is a beep tone detection circuit for detecting the beep tone reproduced during the operation of the above-mentioned answering machine A, and this also detects the dial tone at the start of the paging operation. It's done in a circuit.

Further, 12 is a voice detection circuit having the same function as 9 described above. Reference numeral 13 denotes a third control section, and as described above, the output of the first beep tone (51 in FIG. 2) detected after the response message by the beep tone detection circuit 11 is applied to the input terminal (10). Then, a built-in timer (first timer) with an operating time of several seconds starts, and when the output of the audio detection circuit 12 is applied to the input terminal (II) during this several seconds of timer operation, the output terminal (12) becomes L. The level is maintained continuously and the second beep tone (triple tone) generator of I4 is not driven. In this way, the output terminal (
12) is held at L level, when the output terminal (14) is switched to H level during paging operation, which will be described later, 17 is output via inverter 15 and AND gate 16.
The fourth control section of the controller can be started, and the output of
The system is configured to drive the speed dial generating unit No. 9 to call a specific person. Further, after the output of the beep tone detection circuit 11 is applied to the input terminal (10), if the output of the audio detection circuit I2 is not applied to the input terminal (11) during the several seconds of timer operation, the several seconds of timer operation ends. At the same time, the second beep tone (triple tone) generator 14 is driven to send out a triple tone shown at 55 in FIG. In addition, when the called party C (specified person) responds due to the paging operation, the output terminal (13) goes to 75fH level, and the speed dial generator generates a special signal set by the digital switch 18. By sending this to a specific person, it is possible to identify where the paging is coming from. This special signal may be a combination of different single frequencies instead of the DTMF signal of the telephone.

In addition, when the specified person responds as described above, a timer of about 20 seconds (second timer) built in the third control unit 13 is started, and when the timer operation ends, one shot is emitted from the output terminal (15). The fourth control unit 17 outputs a pulse of
is reset to turn off relay y-2, contact v2
-1 to release the closure on the paging device side B.

This device is composed of the above-mentioned parts, and their functions will be specifically described below.

When a force is applied to the terminal (1), the time constant circuit and flip-flop circuit built in the first control unit 2 maintain the relay Y-l in the operating state via the output terminal (2). Line transformer LTI by contact v1-1
The telephone lines L1 and L2 are brought into a closed state via the telephone line L1 and L2. At this point, the ringing signal stops ringing and you are in a talking state. At the same time, the output terminal (3
) outputs a pulse, and when the pulse is input to the input terminal (5) of the second control section 3, the built-in drive circuit drives the response tape T-l. Therefore, a response message (5 in Figure 2
Q) is reproduced by the recording/reproducing head RPH-l, and the amplifying circuit 4.
After being amplified in step 5, it is sent to the calling party via the line transformer LTI. After this response message, a beep tone (51 in FIG. 2) is recorded by a known means, and the beep tone is detected by the beep tone detection circuit 6, and the detection output is sent to the input terminal of the second control section 3. (6) causes the response tape T-1 to stop driving and at the same time, the reception tape T-2 to be driven in a recording state. Or put the receiving tape T-2 on standby in recording state,
The reception tape may be started after the voice detection circuit 9, which will be described later, detects the voice of the caller. On the other hand, the above-mentioned beep tone is sent to the telephone line via the line transformer LTI, but it is also detected by the beep tone detection circuit 11 via the capacitor Cl, line transformer LT2, and amplification circuit 10, and this detection output is sent to the telephone line via the line transformer LTI. 3 is input to the input terminal (10) of the control section 13. At this point, the first timer of several seconds built into the third control section 13 mentioned above starts. After this timer starts, the subsequent operation is 2.
Divided into two. One case is that the caller's voice is applied before the timer ends, and the other case is that the caller's voice is applied after the timer ends. When the voice from the caller is applied before the operation of the Ushizu timer ends (52 in A in FIG. 2), the voice -9= is detected by the detection circuit 12 via the line transformer LT2 and the amplification circuit 10. The detection output is sent to the third control unit 1.
It is input to input terminal 3 (!I). This is the first part mentioned above.
Output terminal (12) by AND action with the output of the timer
It acts to maintain the L level. Therefore, the terminal α of the AND gate 16 is held at H level via the inverter 15. Similarly, the terminal is held at L level here, and the subsequent operation will be described later. On the other hand, the voice of the caller is also detected by the voice detection circuit 9 via the line transformer LTI and amplification circuit 8, and the detection output is input to the input terminal (7) of the second control section 30, and the voice ( The receiving tape T-2 is driven in a recording state while the voice is being input without interruption for a certain period of time (message), and the message from the caller is recorded via the recording/reproducing head RP'H-2. Record. Also, the voice from the caller is detected by the voice detection circuit 12.
It is also detected by , but in this case, each output of the third control section 13 is held at the current state while the voice from the caller continues.

Now, when the caller puts the telephone on the hook and the voice is interrupted for a predetermined period of time, the output of the voice detection circuit 9 disappears and the recording of the reception tape T-2 is canceled via the second control section 3. At the same time, a pulse is output from the output terminal (8) to reset the first control section 2, turning off the relay Y-l and releasing the connection of the telephone line. Furthermore, response tape T
-l is rewound to the starting point for cueing and then restored to the standby state. Note that the response tape starting point detection circuit is not shown because it is well known. On the other hand, the caller's on-hook status is also detected by the voice detection circuit 12, and when the detection output disappears, the output terminal (I4) of the third control unit 13 is switched from the L level to the H level, thereby causing the above-mentioned AND Activates the gate 16 and uses its output C to activate the fourth control unit I.
Start 7. First, a built-in flip-flop turns on relay y-2, and its contact v2-1 connects telephone lines L1 and L2. Since the dial tone is now sent from the station to the paging device B side, it is detected by the beep tone detection circuit 11 which has the same function as the continuous tone detection function. As is clear from the figure, the illustrated answering machine A and the paging device are completely independent, and the answering machine A can freely select the model according to the user's preference. Therefore, as mentioned above, even if the caller goes on-hook, answering machine A
The recovery time varies, and even if the paging device B starts and detects a dial tone as described above, there may be cases where a silent or busy tone is received. If the dial tone is not detected in this way, the output terminal (14) of the third control section 13 is returned to the L level, and at the same time a pulse is output from the output terminal (15) to reset the fourth control section I7. As a result, after the relay y-2 is turned off and the telephone line is disconnected, the timer (third timer) built in the third control unit 13 restarts the relay y-2 approximately 10 seconds later. And when a dial tone is detected,
The enable signal is sent from the output terminal (16) to the fourth control unit 17.
By inputting to the input terminal (17) of the output terminal (1
9), the speed dial generator 19 is driven to sequentially send out three-digit speed dials. After sending the speed dial, a ringback tone is returned, which is detected by the voice detection circuit 12. When the called party (specified person) answers, the ringback tone detected by the voice detection circuit 12 disappears, and it is assumed that the specified person has responded, and the third
By switching the output terminal (13) of the control unit 13 to the H level and driving the speed dial generator with a special signal set by the digital switch 18, such as ° "pee per per", a specific person who hears this signal can hear it from anywhere. It is now possible to tell whether the page is paging or not. Alternatively, this special signal may be decoded and displayed using a tone decoder. Since such a call state is maintained for about 20 seconds by the second timer built in the third control section 13, the reception tape T can be switched on by remote control operation as necessary, although this is not shown as it is publicly known. It is also possible to remotely listen to messages recorded on -2. Now, when the operation of the second timer ends, the outputs of the third control section 13 and the fourth control section are reset to the initial state, and standby for the next paging operation.

Next, if the caller does not speak for several seconds even after hearing the first beep tone (51 in Figure B in Figure 2), the first timer built in the third control unit (several seconds) is activated. and the output of the audio detection circuit I2 cannot be ANDed, and in this case, the output terminal (12) is held at H level as described above. Therefore, through the inverter I5, the AND gate 1
The terminal α of the fourth control unit !6 is held at L level, regardless of the output of the output terminal (14). The fourth control section 17 cannot be activated via the start terminal ST of 7, and the relay y-2 and the speed dial generating section 19 can be energized, but cannot perform the paging function.

On the other hand, when the paging action is interrupted by holding the output terminal (12) at H level as described above, the second beep tone generating section 14 is driven by the signal from the same output terminal (I2), 55 in Figure 2 (B)
It is designed to send out the triple tone shown in . Even in this case, the receiving tape is driven by the output of the voice detection circuit 9, and only the message can be recorded. When the caller goes on-hook, the answering machine A is restored after a predetermined period of time, and at the same time the output of the voice detection circuit 12 disappears, the output terminal (12) of the third control unit I3 returns to the L level. The inhibition of paging operation is canceled and the next paging operation is waited for.

Although the circuit example described above is mainly composed of logic ICs, it goes without saying that it can also be composed of a one-chip microprocessor. Further, since the triple tone generating section 14 described above is independent, it can be omitted if necessary without directly affecting the paging function, and other tones can also be used in place of the triple tone.

〔effect〕

As described above, the present invention provides a function in which the conventional device always pages the person when a message is received, or a means in which the caller calls the person by pressing a code number on a telephone. Even in the most popular regions, it is now possible to select the method of calling the person or simply leaving a message without calling the person, depending on the timing of the response term. In fact, it can be said that the practical effects of this type of device have been increased.
