Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, as tapes used for answering machines, endless tape has been used for answering tapes, and ordinary cassette tapes have been used for receiving tapes. However, as a popular type for home use, a method has been proposed that uses a single tape (hereinafter referred to as a single cassette) and simplifies the tape drive mechanism and circuit. However, in conventional single cassettes, in order to avoid using endless tape as a response tape, response words are blown into a single tape with an end at intervals dozens of times, and the above-mentioned intervals are used as reception tape. use,
It was used to record messages from customers. Therefore, in order to set up the device, the user had to perform a complicated operation in which the user had to record the response terms several dozen times on a single cassette. Therefore, since many people who originally used answering machines were lazy, it was contradictory to require such a thing as described above. Therefore, these devices were beyond the limits of practical use. However, unless endless tape is used, this is the current situation. In the present invention, this has been basically modified so that the response term can be recorded only once in a single cassette and used each time a call is received.

The structure and operation of embodiments of the present invention will be explained below.

In Figure 1, L1 and L2 are telephone lines, LT

Also, 2 is a delay circuit to provide a non-recording section of about 1 second between the famous messages described later, and IC-2 is a counter that increases the count each time IC-1 is set and stores the number of incoming calls. I'll let you. 3 is a recording tape for recording response terms and incoming messages on a single tape as shown in FIG. 2, which will be described later; 4 is a rotary switch that opens and closes while the recording tape 3 is running; Reference numeral 5 denotes a starting point detection circuit for detecting the starting point of the recording tape 3 via the rotary switch 4. Also, M1 is a motor for driving the above-mentioned recording tape 3, but if solenoid SD is working at the same time, the tape 3 is normally fed, and motor M1
When the tape 3 is working alone, the tape 3 is rewound. Further, M2 is a motor for fast forwarding the tape. In addition, EH is the erase head common to the first and second tracks of the recording tape 3, and RPH-

Also, 8 is a delay circuit of approximately 0.1 seconds that is activated when the final trailing edge of the control signal of the second track is detected during the above-mentioned fast forwarding, and this device records data via the flip-flop IC-20 that is set by this output.

Although not specifically shown in the drawings as it is well known, the circuit controls the recording tape 3 through the load relay Y-R. Various remote control operations such as playback and backspace can be performed. Further, when an incoming call is received after the recording tape 3 has finished recording a predetermined number of incoming messages for a predetermined number of calls, for example, five calls, a circuit for returning to a standby state after transmitting the first half of the message dedicated to response terms; That is, IC-21, IC-22, IC-23, capacitors C7, C8 and diode D
It has a control circuit at the end of the tape consisting of 3 and D4.

On the other hand, FIG. 2 illustrates the recording distribution of the recording tape 3. As shown in FIG. That is, 100 is a first track on which audio is recorded, and 101 is a second track on which control signals are recorded. More specifically, 102 is the first half of the response term, and is a response-only message such as ``This is Hashimoto, but I'm away at the moment.'' For example, "This is Hashimoto, but I'm away at the moment." Further, the second half of the response term 104 includes words that prompt recording. For example, ``If you are in a hurry, the answering machine will accept your request and we will contact you later. Please briefly explain your request.''
It's like, "Please." Further, 103 is a non-recording section of 1 to 2 seconds provided to distinguish between the first half and the second half of the above-mentioned response term. Further, 105 is a control signal recorded on the second track during the recording of the above-mentioned response term, and this is used to determine the reproduction section of the response term, as will be described later. Further, 107 and 110 are recorded incoming messages, and in this figure, five calls are recorded. Furthermore, control signals 108 and 111 are recorded on the second track corresponding to this incoming message when this incoming message is recorded. And between each incoming message there is about 1 like 106, 109, 112.
A second unrecorded section is automatically provided.

The present invention is composed of the above-mentioned parts and has various functions as described below.

First, it is assumed that the first half 102, the second half 104, and the control signal 105 of the response term shown in FIG. 2 have been previously recorded from the starting point of the recording tape 3. When this tape is set and power is supplied to this device, flip-flop IC-5 is set via terminals 1 and 3 of NOR gate IC-4 due to the time constant of resistor R1 and capacitor C1, so the terminals of IC-5 are L and Q. becomes H. When IC-5 becomes L, transistor Tr1 is turned on via terminals 2 and 3 of OR gate IC-7 to drive motor M1. On the other hand, through Q of IC-5 and gate
Since terminal 3 of IC-8 becomes H, the transistor
Tr2 is off and cannot drive solenoid SD. As described above, when M1 is driven and SD is not driven, the recording tape 3 is rewound. During this winding, the rotary switch 4 repeats opening and closing, and charges the capacitor of the starting point detection circuit 5, which is shown as a block diagram since it is well known. When it is rewound to the starting point, the rotary switch 4 stops opening and closing and the charging of the above capacitor stops, and the discharging of the above capacitor ends in 2 to 3 seconds, so the output of the starting point detection circuit 5 causes the above IC-5 to stop. Reset and stop driving motor M1. The apparatus is now in a standby state, with the recording tape 3 as the starting point, waiting for an incoming call from a third party. Now, when a ringing signal enters L1 and L2 of the telephone line, flip-flop IC-1 is set through ringing amplifier 1, so relay Y-1, which is its load, is held in an operating state, and its contact _y1 Since a DC loop is formed through _-1 , the calling signal stops and a mutual communication circuit is established. Now, when the above IC-1 is set, the signal is passed through the delay circuit 2 to the terminal 2 of the AND gate IC-6.
And set terminal 2 of IC-8 to L. Terminal 1 of IC-6 and terminal 1 of IC-8 are L due to terminal Q of IC-19, which is a fast-forwarding IC described later, so transistor Tr1 is turned on via terminals 1 and 3 of the OR gate, and motor M1 is turned on. to drive.
At the same time, as is clear from the above, terminal 3 of IC-8
Since is set to L, transistor Tr2 is also turned on and drives solenoid SD. As mentioned above, when M1 and SD are driven simultaneously, recording tape 3
be sent normally. Here, as mentioned above, the first half of the response term 102 recorded on the first track of the recording tape 3 is played back by the recording/playback head RPH-1 and transmitted via the analog switch SW3, the amplifier circuit 7, and the analog switch SW4. The line reaches the transformer LT and the telephone line is sent out. Since the recording tape 3 is not at the end this time (the case of the end will be described later), the unrecorded portion 103 and the response word 104 in the latter half are continuously played back. On the other hand, the control signal 105 recorded on the second track is played back by the recording/playback head RPH-2, and is connected to the analog switch SW2 and capacitor C.
4. After the width is increased by the expansion circuit 6, the diodes D1 and D
2. Since this control signal is rectified and smoothed by capacitor C6, the Schmitt circuit
Clock terminal C of counter IC-12 is held at L via IC-11. Note that this counter counts when the terminal C switches from L to H. Subsequently, when the reproduction of all the response words 104 and the control signal 105 in the latter half is completed and the non-recording section 106 is reached, the diodes D1 and D2 are switched off.
Since the DC output due to this disappears, the count number of IC-12 becomes 1 through IC-11, and terminal 1 becomes H. It should be noted that this counter IC-12 is reset from the reset state when it enters the loop as described above. Now, with this count number 1, terminal 2 of AND gate IC-13 is H, terminal 1 of IC-13 is connected to terminal 1 of counter IC-2,
This IC-2 increases the count number each time a call arrives due to the output of IC-1 (up to 5 as described later), and when the first call arrives like this, terminal 1 of IC-2 goes high.
It is. Therefore, since terminal 3 of IC-13 becomes H, flip-flop IC-19 is reset continuously from the standby state via terminals 1 and 7 of OR gate IC-18. Although not shown, the IC-19 is reset when the device is set to standby mode. Therefore, IC-
When the count number 12 reaches 1, the clock terminal C of the IC-19 is set to H, and the function of inverting the IC-19 is prevented by applying a reset. Incidentally, when the IC-19 is reversed, the motor M2 is driven and acts to fast-forward the tape 3, but if this is the first incoming call, the incoming message 107 is continuously recorded immediately after the unrecorded section 106. Therefore, such fast forwarding is unnecessary only for the first time. Note that this fast forwarding will be described later. Now, if IC-19 is not inverted (set), the terminal of IC-19 is H, so the terminal D of the D-type flip-flop IC-20 is H, and there is a delay after the above-mentioned control signal disappears in this H state. Approximately 0.1 seconds later due to circuit 8
IC-20 with clock terminal C of IC-20 set to H
Invert (set) When the terminal Q of IC-20 switches from L to H, the timer circuit 9 is started for about 30 seconds, and the analog switches SW1 to SW4 are switched according to the output of the timer circuit 9, and the recording/playback head RPH is switched.
1. Switch RPH-2 to recording mode. Here, an incoming message from a third party coming in via the telephone line is recorded via the line transformer LT and the amplification circuit 7 on the first track 107 of the recording tape 3 as shown in the figure. At the same time, on the second track 108, a control signal is recorded by a multivibrator (oscillation frequency of about 1 KHZ) consisting of IC-9 and IC-10. Next, the above timer circuit 9
When the time-off occurs after about 30 seconds, its output becomes H, which causes the flip-flop IC-1 to
Since IC-1 is reset through reset terminal R1 of Y-1, relay Y-1 is restored and the loop is opened. On the other hand, the delay circuit 2 causes the motor M1 and solenoid SD to be restored and the recording tape 3 stops running after about 1 second, so there is no recording area 109 on the tape.
occurs, and at the same time the flip-flop IC for recording
20. When the counter IC-12 is also reset and the output of the delay circuit 2 returns to H, the pulse of the capacitor C2 causes the above-mentioned cue flip-flop to be activated via the terminals 2 and 3 of the OR gate IC-4.
Set IC-5, rewind tape 3 to the starting point, and restore to complete standby state. In addition, the counter
IC-2 stores the above-mentioned incoming call 1.

Next, when the second call arrives, the first
The operation is different from that when the second incoming message is received, and when the sending of the response term is completed, the section of the incoming message 107 recorded as described above is fast-forwarded, and then the next incoming message 110 is recorded. A detailed explanation will be given below, but portions that overlap with the above will be briefly described. Now 2
Relay Y-1 is kept in the operating state by the second ringing signal, forming a loop. At the same time, IC-2 becomes count number 2 and holds its terminal 2 at H level. The response terms 102 and 104 of the tape 3 are reproduced from the beginning as described above, and when the unrecorded part 106 is reached, the counter IC-12 becomes 1 and its terminal 1 is set to H level. At this point, the clock terminal C of the fast-forward flip-flop IC-19 is set to H, and the IC-19 is inverted. When the first call is received, the AND gate IC is activated at this time.
Since IC-19 was reset through -13, IC-19 was not reversed and tape 3 was not fast-forwarded, but this time IC-13's terminal 1 is L and its terminal 3 is L. There is no reset to terminal R of IC-19, so IC-19 is inverted (set). When the terminal of IC-19 becomes L, the transistor TR3 is turned on to drive the fast-forward motor M2 and start fast-forwarding the tape 3.
At this time, the terminal Q of IC-19 becomes H.
The motor M1 is deactivated through IC-6, and the solenoid SD is deactivated through IC-8. Now, even during the above-mentioned fast forwarding, the control signal 108 recorded on the second track is transmitted to the recording/playback head RPH as described above.
-2 and charges the capacitor C6 via the amplifier circuit 6, but when it reaches the non-recording section 109, the charge in C6 is discharged and the Schmitt circuit IC-11
Set counter IC-12 to count number 2 via . Here, when terminal 2 of IC-12 becomes H, terminal 2 of AND gate IC-14 becomes H. I C-
Terminal 1 of IC-14 becomes H due to terminal 2 of counter IC-2, so terminal 3 of IC-14 becomes H and resets IC-19 via OR gate IC-18, so motor M2 is stopped and the fast-forward state is released. , the motor M1 and solenoid SD, which had been stopped during fast forwarding as described above, are driven again, and the tape 3 is again driven normally. Further IC
-19 is reset, the recording flip-flop IC-20 is set as described above, and the incoming message is recorded at position 110 on tape 3 as described above. Subsequently, when the timer circuit 9 times out, the loop is opened as described above, a non-recording section 112 is created by the delay circuit 2, and then the tape 3 is rewound to the starting point to restore the complete standby state. do. Note that the incoming message cannot be recorded during the fast forwarding mentioned above, so during this time
The outputs of the multivibrators of IC9 and IC-10 may be sent as beep tone signals via the line transformer LT.

Next, when the third incoming call arrives, the incoming message 107, 1 is recorded in fast forward after the response term has been sent as described above.
11, the current incoming message is recorded after the unrecorded part 112, and after the recording is finished, the tape 3 is rewound to the starting point and the standby state is restored.

Next, when the above-described operation is repeated and the tape 3 reaches its end, it functions as a response-only machine as described below. Here, the end of the tape is the counter IC.
The number of incoming messages that can be recorded is determined by the output method in step 2, which means that the recording of the last incoming message has been completed. In this embodiment, the tape ends when recording of incoming messages for five calls is completed.

Now, when the fifth call arrives, the counter IC
The count number of 2 becomes 5, and the terminal 5 becomes H, pulling the terminal 2 of the NAND gate IC-21 to H. I C
Terminal 1 of -21 is L because it is connected to the terminal of flip-flop IC-1, which is set when a call is received. When IC-1 is reset after recording the incoming message, the terminal of IC-1 becomes H and the terminal 1 of IC-21 becomes H.
At this point, terminal 3 of IC-21 becomes L, flip-flop IC-22 is set, and its terminal Q becomes H.
The IC-22 remains set until the remote control operation described later is performed. When the next call arrives in this state, a loop is formed as described above, and reproduction of the first half 102 of the response term is started from the beginning of the tape. This response term is amplified by the amplifying circuit 7 and then connected to the diode D via the capacitor C7.
3. It is rectified by D4, charges the capacitor C8, and keeps the input of the inverter IC-23 at H.
Therefore, during playback of response terms, AND gate IC-2
Terminal 1 of 4 is L. Terminal 2 of IC-24 is at H level due to terminal Q of IC-22 mentioned above. IC-2
Terminal 3 of No. 4 becomes H after about 1 second due to the time constant circuit of R10×C9 after the loop is formed. Therefore, while the response term 103 is being reproduced, the terminal 4 of the IC-24 is at L, so it is not reset to IC-1. When it reaches the non-recording part 103, the above C8 cannot be charged and the charge is discharged after about 1 second, so terminal 1 of IC-24 is set to H via inverter IC-23, so the AND condition is satisfied. Since it is established and the terminal 4 of IC-24 is set to H, the reset terminal R of IC-1 is set.
Reset IC-1 via 2 and relay Y-1
is restored, the loop is opened, and the cue flip-flop IC-5 is set via the delay circuit 2, capacitor C2, and OR gate IC-4, and the tape 3 is rewound to the starting point to wait for the next call. Note that while the counter IC-2 is working as a response-only machine, the terminal CE (clock enable) of the counter IC-2 is open, and the count number does not exceed 5.

Next, a case will be described in which the owner of this device operates the remote control from a telephone outside the home. When a remote control signal is sent during playback of a response term, the signal passes through the line transformer LT, amplification circuit 10, micro fork F, and rectification and smoothing circuit 11, sets the remote control control circuit 12, and operates the load relay Y-R. hold in state.

Since the relay Y-R is well known, a reproducing circuit for the first track 100 of the tape 3 is formed using operating points not shown. This may be an analog switch. At the same time, the counter IC-2, flip-flop
Reset IC-22. As a result, the incoming call after this remote control operation is completed is regarded as the first incoming call. Further, the tape 3 is rewound to the starting point by the output of the remote control control circuit 12 and reproduced from the starting point, but these are not shown because they are well known.

As described above, in the present application, if the user records the response term only once for a single cassette,
The company also provided an innovative device that could automatically record messages for reception while performing skip operations. In order to achieve a similar purpose to the present application, Japanese Patent Publication No. 56-30982 (Japanese Patent Application No. 1983-
107233), but as you can see from the specification, the distance between the first head and the second head is large enough to accommodate messages for response and reception. Because it was necessary, it could not be used in the drive mechanism of ordinary compact cassette tapes, etc., and it was not put into practical use.
By adopting a completely different method, the present invention has made it possible to use the mechanism that uses a normal compact cassette tape as is. Furthermore, when the incoming message is recorded up to the end of the tape, the present invention automatically switches to an answering-only answering machine. After the answering machine has been recorded, it is switched to answer-only mode, increasing the practical effectiveness of the answering machine.
