Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic telephone answering device that allows a message to be conveyed to a caller to be rerecorded by remote control.

When a caller makes a call, the automatic telephone answering device activates an endless answering tape and tells the caller, for example, ``I'm away at the moment, so if you have anything to do, I'll record it on tape.'' Please talk to me.

'', and the caller then speaks if there is a message to be conveyed, and the message is recorded on a receiving tape separate from the endless tape. By the way, as a result of receiving many calls from many callers while you are away, messages may be recorded up to the end of the receiving tape, making it impossible to record the messages from the callers. In this case, it is necessary to change the contents recorded on the endless tape. Taking these points into consideration, the present invention is an automatic telephone answering device that allows the owner to change the content of the message to be transmitted to the caller by remote control, and will be described below with reference to the drawings.

1 is a tape recorder section, and 2 is a control section. The tape recorder section 1 includes a recording and reproducing head 3 for endless tape, an erasing head 4, and a recording and reproducing head 5 for receiving tape.
, erasing head 6, switches 7, 9, 1 for switching these
0, amplifier circuits 12 and 13, beep tone circuit 14, bias oscillation circuit 15, remote control circuit 16 that passes and amplifies only remote signals, voice control circuit 17 that generates control signals depending on the presence or absence of audio signals, tape position detection circuit 18, calling Ring-up circuit 19 for detecting signals
, a transistor 21 connected in series with a motor 20 for driving the endless tape, a motor 22 for driving the received signal tape, a transistor relay 24, and L.
It has an S relay 26 and the like. The control section 2 is composed of several flip-flops, an OR circuit, and a NAND circuit. Next, the operation of the present invention will be explained.

{1' Automatic answering state A message from the caller is automatically recorded as follows.

First, when the caller turns the dial and sends a paging signal, the paging signal is supplied to the ring-up circuit 19 via lines L, , L2, part of it is sent to the flip-flop 31 via the OR circuit 30, and the rest is sent to the flip-flop 32. These flip-flops 31 and 32 are set. When the flip-flop 31 is set, the transistor 21 is turned on and the motor 20J is rotated.
Furthermore, by setting the flip-flop 32, the transistor 27 is turned on, which excites the LS relay 26 and turns on the LS.
Turn on the switch 33. At this time, since the output of the AND circuit 35 is "1", the switches 7 and 10 are turned on.
0, line transformer 34, and LS switch 33, it is added to lines L and L and transmitted to the calling party.
2. After the message to be transmitted is finished, the beep tone signal recorded on the endless tape is played back. The beep tone circuit 14 then generates a signal which sets flip-flop 36 and then flip-flop 38. By setting the flip 20 flip 38, the transistor 23 is turned on, causing the motor 22 to rotate. At this time, the output of the AND circuit 35 becomes "0", so the switch 7
. Therefore, the message from the caller applied via the lines L, L is applied to the head 5 via the switch 9, the amplifier circuit 12, the bias oscillation circuit 15, the switch TR-2, and is recorded on the receiving tape 3. . When the endless tape goes around once, the tape switch 41 is turned on by a steel foil or the like.

Then, the flip-flop 31 is reset. When the voice further disappears, output 4 of the voice control circuit 17
The power becomes level "1" and the flip-flop 32 is also reset, returning to the standby state. [21 Remote Playback To play back messages recorded while you are away, proceed as follows.

First, while sending a message to the caller, the owner sends a remote signal on a defined frequency. At this time, the Q output of the flip-flop 36 is at level "0" and the Q output is at level "1", so when the output of the remote control circuit 16 becomes level "1" due to the addition of the remote signal, the output of the AND circuit 42 becomes level “1”. As a result, flip-flop 38 is set, transistor 23 is turned on, and motor 22 begins to rotate. The flip-flop 28 is also set, and the output of the OR circuit 29 becomes "1", turning on the transistor 25 and turning on the transistor relay 24. Then switch TR-1
, TR2 are switched to a state different from that shown, and the signal reproduced by the head 5 is transmitted to the lines L, L via the amplifier circuit 12 and the like, and transmitted to the owner. After that, it flips every time there is a remote signal. The plunger 43 is triggered to turn the plunger 44 on and off to perform rewinding or playback. When the receiving tape is rewound to the stereotaxic layer, a signal is generated from the tape position detection circuit 18 to reset the flip-flop 43 and turn off the plunger 44 to bring it into the playback state. At the same time, a timer 45 is set, and if there is no remote signal after a certain period of time, the output is turned on. When the receiving tape is played back and there is no sound, a signal is generated from the voice control circuit 17, which resets the flip-flop 38 and starts the timer 45.
Set. Turns on the output if there is no remote signal within a certain period of time. This sets the flip-flop 31. When the flip-flop 31 is set, the motor 20 rotates, and when the beginning of the endless tape is reached, the flip-flop 32 is reset to return to the standby state. Legs Changing the recording of messages by remote control,
The message recorded on the endless tape can be changed to a different message by remote control as follows.

The owner sends the ring signal and the remote signal is sent after the device has finished sending messages to the caller and plays a beep tone. That is, when the beep tone signal is reproduced, flip-flops 31 and 36 are set. Then, when a remote signal is applied to the remote control circuit 17 and the output of the remote control circuit 17 becomes level "1", since the flip-flop 36 is at level "1", the AND circuit 46 becomes level "1".
Then, the flip-flop 47 is set. As a result, the flip-flop 38 is reset, the motor 22 is stopped, the output of the AND circuit 35 becomes level "0", and the erasing head 41 and switch 9 are turned off. When the endless tape goes around once, OR circuit 48, AND circuit 4
9 becomes level "1", and the motor 20 swivels.
Since the flip-flop 32 is in the set state, the LS relay 26 remains on. When the second IJ mote signal is input, the AND circuit 50Z becomes level "1", the flip-flop 51 is set, the AND circuit 52 and the OR circuit 30 become level "1", the flip-flop 31 is set, and the motor 20 is turned on. AND circuit 52, OR circuit 5
3 becomes level "1", the erasing head 4 is turned on, the OR circuit 40 becomes level "1", and the switch 9 is turned on.

As a result, when the owner sends a message to be changed to the receiver and speaks, the message is applied to the line transformer 34 via lines L and L2, and then to the switch 9 and the amplifier circuit 12.
, are supplied to the head 3 via the bias oscillation circuit 15 and switch TR-2, and are recorded on an endless tape.

At the same time, the timer counter 54 starts counting up and counts the recording time. When the necessary recording is completed, input the third IJ mote signal. This sets the flip-flop 55, stops the timer counter 54, and sets the AND circuit 52 and OR circuit 53 to level "1".
When the endless tape goes around once, the tape switch 41 is turned on and the OR circuit 4 is turned on.
8 becomes the next bell “1”, but the AND circuit 49 becomes the next bell “1”
0'', the flip-flop 31 remains set and the motor continues to rotate up to 2 times.And the AND circuit 5
The output of 6 becomes "1", and the flip-flop 57
This sets the timer.

Counter 54 begins counting down. When the countdown reaches 0, the level of the Q core terminal becomes ``1'', the flip-flop 18 is reset, and the output of the OR circuit 53 becomes ``1''.

This causes the beep tone circuit 14 to operate to generate a beep tone and record the beep tone on the endless tape.

After the endless tape has completed one rotation, the device is reset. As described above, the automatic telephone answering device of the present invention has LS when outgoing to convey a pre-recorded message to the caller and during response recording to record a message from the caller.
Since the state of the flip-flop that operates the relay or each motor is different, both remote listening and remote recording can be performed by remote control based on the difference.
