Description

[Detailed Description of the Invention] The applicant previously proposed that in an automatic telephone answering and recording device in which the answering tape and the receiving tape operate independently, the time when a call was received and the cumulative time that the receiving tape ran from the beginning. He proposed a device that would record the message on a receiving tape and allow the user to listen to it as a voice over a telephone line even from a remote location. However, the present invention provides a means by which even the simplest type of answering machine can perform the above-mentioned functions. In some simple answering machines, a general tape is divided into a plurality of parts, and the upper part records the response words and the lower part records the received message. Alternatively, even if the response tape and reception tape are separate, both tapes are driven simultaneously when a call arrives, and the reception tape is controlled by one cycle of the response tape. .
An even simpler example is that on a general tape, response terms are sequentially recorded dozens of times, such as a response message, a reception message, a second response message, and a second reception message. There is a so-called single cassette system in which recording is made during the drive.
In any case, when the user goes home and listens in such a case, it is very tedious to listen to the response terms many times, so the receiving tape is silent during the section corresponding to the response terms. When the receiver tape is at the position where it should be recorded, it records the receiver message, and when it is played back after returning home, only the receiver message is played back without hearing the response words many times. There are many things that have been devised. In such a case, considering the overall playback time of the receiving tape, the receiving tape or receiving track is also running at the same time in the section where the response term is being sent, so if this is to be played back, this period is considered wasted time. It's summery. The gist of the present invention is to utilize this dead time to record the current time when a telephone call is received, thereby making effective use of the dead time of the receiving tape, which is the biggest drawback of simple answering machines.

In other words, the purpose of the present application is to run a recording medium having two tracks, one for response and one for reception, and to record each message on each track. To make it possible to record the time of arrival of a call in a section of a commercial track.

The structure and operation of an embodiment of the present application will be explained below. In this embodiment, a response track on which response words are recorded and a reception track on which a reception message is recorded are connected by upper and lower channels of the same magnetic tape. I will now describe the answering machine I created.

That is, in Fig. 1, L1 and L2 are telephone lines, LT is a line transformer, 1 is a ringing amplifier for detecting a calling signal, 2 is a transistor, A is a relay that serves as a load for the transistor, and its contacts are They are illustrated as a-1, a-2, and a-3. 3 is a differentiating circuit that outputs one negative pulse when the transistor 2 is turned on; 4 and 5 are set by the output of the differentiating circuit 3, and are connected to electrodes CP-1, CP-2, CP, which will be described later.
The RS type flip-flops 6 and 7, which are reset by -3, are analog switches such as MC14066, which conduct the audio signal in the direction of the arrow while the control terminal 3 is at H level. Also, number 8 is a voice clock that notifies the time by voice, such as the CT-660 model made by Shaap Co., Ltd.
When the push button 9 is pressed, the current time at that moment is output to the built-in speaker 10. Further, EH-1 and RPH-1 are an erasing head and a recording/reproducing head for the first track shown in FIG. Further, EH-2 and RPH-2 are an erasing head and a recording/reproducing head for the second track shown in FIG. Further, AMP-1 and AMP-2 are amplifier circuits for the first track and the second track. In addition, CP-1, CP-2, and CP-3 are conductor foils PP-1 and CP-3 pasted in a staggered manner as shown in Figure 2.
PP-2, PP-3... and PR-1, PR-2...
Each two electrodes are electrically conductive at the same time due to...
Fig. 2 also shows an endless tape or cassette tape for recording response terms, incoming messages, and time on one tape 11, and between the conductive foils PP-1 and PR-1 mentioned above. The response term is recorded on the first track, the time is recorded on the second track, and the receiving message is recorded on the second track of the conductor foils PR-1 and PP-2, which are used for one cycle of operation after receiving a call. The structure is such that it is repeated continuously on the same tape for each incoming call.

Next, its effect will be explained.

It is assumed that the response term has already been blown in by a known method and that the tape 11 is at the starting point. If there is an incoming call from a third party here, ringing amplifier 1
detects a calling signal, turns on transistor 2, and energizes relay A of the load. At this point, contacts a-1, a-2, and a-3 of relay A are made.
Since a loop is formed by contact a-1 via line transformer LT, the ringing signal stops ringing. At the same time, the motor M is driven by contact a-2 to run the tape 11 shown in FIG. 2 in the direction of the arrow from point _t0 . At the same time, when the transistor 2 is turned on, the pulse generated by the differentiating circuit 3 sets the two flip-flops 4 and 5. At this point, the output Q of the flip-flop 5 becomes H, and this output applies a bias to the base of the transistor 2 via the resistor R1 to keep the relay A in the operating state. Also, the output Q of the flip-flop 4
becomes H and becomes L, so the analog switch 6 is on and the analog switch 7 is off, so the response term 1 recorded in the first track of the tape 11 that has started running as described above is from _t0 . The signal is reproduced by the recording/playback head RPH-1, amplified by the AMP-1, passed through the analog switch 6 mentioned above, and sent out to the line via the line transformer LT. Further, since the analog switch 7 is turned off, signals coming in via the line transformer LT are blocked, and no recording of signals coming in from the telephones L1 and L2 is performed on the second track. That is, in this embodiment, the analog switch 7 and the flip-flop 4 constitute means for blocking a signal from entering the receiving track from the telephone line during the transmission of a response term.
However, when the other contact a-3 of the relay A is made, the same effect occurs as when the push button 9 is pressed.
The current time displayed at that time is uttered as "0:00", and the output is applied to the amplifier circuit AMP-2 via resistor R2, amplified, and then output to the recording/playback head RPH.
- 2 from position t ₀ of the second track in FIG. 2 (time 1). That is, in this embodiment, the contact a-3 of the relay A, the resistor R2, and the amplifier circuit
AMP-2 and recording/reproducing head RPH-2 make the audio clock 8 utter the current time, and constitute a means for recording the current time on the receiving track.

Next, the transmission of response term 1 is completed, and the conductor foil PR-
1 shorts electrodes CP-2 and CP-3, flip-flop 4 is reset and its output Q becomes L,
Q returns to H, the analog switch 6 is turned off,
Analog switch 7 is turned on.

At this point, the sending of response terms is completely cut off, and messages for reception from a third party that come in via the telephone line are transferred to the line transformer and the analog switch 7.
After being amplified by the amplifier circuit AMP-2, the message is recorded on the second track of the tape 11 via the recording/reproducing head RPH-2 (reception message 1). Note that although this contact point a-3 is closed, the voice clock 8 used is one that utters the time at the moment when it is energized as described above, and the contact point a-3 continues to be in a closed state. Do not pronounce the time with the chisel alone.

Now that the recording of message 1 for reception is complete, the conductor foil
When PP-2 shorts electrodes CP-1 and CP-2, the aforementioned flip-flop 5 is reset and its output Q returns to L, so the bias applied via resistor R1 is cut off and transistor 2 is turned off. Then, relay A is restored. Here, the loop is opened by the contact a-1, and the motor M1 tape 11 is stopped by the contact a-2, but due to inertia of the tape 11, the conductor foil PP-2 is connected to the electrodes CP-1, CP-
It stops at the position where it passes through 2, that is, at the position t1. Contact a-3 is also turned off to wait for the next time utterance. At this point, the device returns to the standby state, repeats the above operations in response to the next incoming call, and returns the tape 11.
Time 2, . . . , received message 2, . . . are recorded on the second track.

When the owner returns home, if the tape 11 is a cassette, he or she can rewind it to the starting point and play only the second track. Before playing each recorded reception message, the owner can check the time when the reception message arrived. It can be heard.

As described above, the present application provides that in a simple answering machine in which a response term is recorded on the response track and a received message is recorded on the reception track, the response term is used when listening to the received message after returning home. If the section reception track corresponding to the section is blank and there is wasted time in its playback time, the reception time when the message was received is recorded there, so you can use it by listening to this. It can be said that the above-mentioned wasted time is virtually eliminated and the practical effect is increased. Conventional systems in which the time of incoming calls was recorded on receiving tapes were already applied for in 1974.
65127 (Special Publication 1977-32611) and other patent applications 1977-88910
(Japanese Patent Publication No. 49-32206), etc., but there is no precedent for the above-mentioned patent, and the present application is the first such patent, and therefore, the applicant claims a patent within the scope described above.
