Description

[Detailed Description of the Invention] A user calls up a remote listening answering machine from outside the home, and while listening to a message from a customer stored in the device by remote control, immediately calls the other party. There are times when you need to contact someone or interrupt a call for other reasons.

At this time, it would normally be preferable to wait a while, stop the tape, and restore the machine, but in some cases this may not be possible. In this case, if the continuation signal described below is not sent, the playback of the receiving tape will stop within a maximum of 6 sands and the device can be restored, and if the continuation signal is sent again, this will cause the above playback to continue to the next one. A method that continues for about 6 Kagami sand intervals is generally adopted. For example, Tokuko Sho 5
It is similar to the device No. 2-8052. In the conventional device, the CR timer determines the interval between the first continuation signal and the next continuation signal to be sent out at 5 or 6 times. To do this, it was necessary to have a timer circuit (hereinafter referred to as the main timer circuit) in which the time was set in advance. For example, according to the accompanying drawing in the aforementioned Japanese Patent Publication No. 52-8052, this interval is determined by the main timer 19 shown in the figure. However, some answering machines are of the so-called simultaneous type, in which the answering tape T-1 and the receiving tape T-2 are driven at the same time. This is the response tape T-
In this method, the running time of the receiving tape T-2 is controlled by the one-round time of the receiving tape T1. There are cases in which two tapes are driven simultaneously by a single capstan, and cases in which the driving time of the receiving tape is controlled by one rotation of the response tape, although the drive mechanism is completely separate.
The present invention is intended to control the drive of the receiving tape by one revolution of the response tape during remote control playback, without having a separate timer mechanism as described above in any of the above devices. The operating principle will be explained below.

In FIGS. 1 and 2, terminals L1 and L2 are telephone line input terminals, which are connected to the telephone line via the primary coil of a transformer LT.

PRE-AMP is a preamplifier, and MF is a so-called microphone using a sound element vibrating element. It is called a fork and is designed to pass only a specific frequency (hereinafter referred to as a remote control signal). Next, AMP is for amplifying the signal through the MF, RT is a delay circuit of 2 to 3 seconds, and Y-1, Y-2, Y-3, and Y-4 are relays. Further, the contact point is indicated as y3-, for example. Therefore, the user first calls this device, operates the loop opening relay Y-1, and puts it into a talking state at its short point, -.
After listening to the response terms from tape T-1, by remote control,
Only the specific frequency signals introduced from L1 and L2 pass through the MF and are delayed by 2 to 3 seconds in the delay circuit RT, after which the relay Y-3 can be activated. (Although this relay Y-4 also works, it is not directly related to the current operation and will be described later.) Relay Y
When -3 is activated, the plunger coil Sd is cut off by the contact seal -. Sd is pinch roller PR-2 (P
Since it is mechanically connected to R-1), pull this pinch roller in the direction of the arrow in the figure. The tape T-2 is then removed from the pressure between the capstan CAP-2 and the pinch roller PR-2, and the tape is released from the normal cabstan drive. Although not shown in the diagram, for example, Kosho Hakama 5
By using a mechanism such as that shown in 2-29123, if the current flowing to Sd is cut off, the mechanism automatically enters a high-speed rewind state, so the tape is rewound at high speed and the remote control signal is not transmitted. From the moment you quit, T-2 goes into play mode and you can listen to the accumulated messages from customers. Up to this point, both FIG. 1 and FIG. 2 are the same, but FIG. In Figure 2, T-1 and T-2 are shown running separately with different drive mechanisms. That is, in FIG. 1, T-
1 and T-2 are both driven by the same motor M. Therefore, even when the above-mentioned T-2 is playing the remote control, the conductor foil P-1 short-circuits the contact electrode CP-1 at the end of T-1 as it goes around T-1, causing the relay Y-2 to operate. After that, points y2-, y2-2 become contact points (black circle side). When the power to motor M is cut off by you, tape running stops. In addition, the soaring signal oscillation circuit and timer are activated by the uniform-2, and an audible signal (hereinafter referred to as a request signal) is transmitted to the caller via the telephone line. Note that this sending time is the time during which a timer is working, and when the set time has passed, the IJ Ray Y-1 is turned off. This is the aforementioned Tsubaki Kimisho 52-
The same principle applies to 8052, and 2 in the figure of the same specification.
The sub-timer circuit indicated by 0 corresponds to the timer illustrated in this application. Then, when relay Y-1 is turned off, the telephone loop circuit is released and the device is restored. However, if the user sends a continuation signal for about 1 second in response to the request signal before the timer expires, the playback will be continued as follows. That is, when relay Y-4 in the figure is turned on as described above, the bush point 4-, falls to the right when facing the figure, releasing the hold on relay Y-2, and the contact 2-, becomes the white circle in the figure. Since the motor M is connected to the side, the motor M is energized again, and the tapes T-1 and T-2 start driving again. Next, T
-1 goes around once, the same process is repeated, and tape T-2 can continue to be played. Furthermore, in the case where T-1 and T-2 have separate drive mechanisms and motors M1 and M2 as shown in FIG. It is controlled by one revolution. However, while the remote control is turned on and tape T-2 is rewound, relay Y-3 is activated as shown in Figure 1.
d has been canceled. Then, when the remote control signal is interrupted, relay Y-3 returns to contact y3-, and Sd is connected to power source B.
Electricity is supplied again from the AT, and reproduction of the tape T-2 is resumed. Further, the motor MI is also energized from the break contact point 3-, and the response tape T-1 is also run. When the response tape goes around, the conductor foil P-
1 short-circuits the other electrode CP-1, the relay Y-2 operates, and the contact y2- cuts off the current to the motors M1 and M2, stopping the response tapes T-1 and T-2. Then, as in FIG. 1, the signal circuit operates at contact 2-2 and outputs a request signal. During this time, tape T-2 has stopped.
When the user sends a continuation signal of a specific frequency for about 1 second in response to this request signal, relay Y-4 is activated and releases the holding of relay Y-2 at y4-, causing tape T-1 to go around one more time. , and thereafter, a decision is made every time T-1 goes around whether to continue reproducing T-2 or not. This time is very accurate because no CR timer or the like is used as in FIG. 1, and if no request signal is sent, the tape T-1 remains in a standby state with its face exposed, waiting for an incoming call. In addition, the contacts y, -2 in the figure are connected to the above-mentioned S after the relay Y-1 is restored.
d, M1, M2, etc. and the power supply. Also, capacitor C2 below y4-, is initially P
This delay is used to smoothly start the motor when CP-1 remains on top of CP-1. Although two examples have been given above, the present application is not limited to the above two examples, but the essence is a type in which a receiving tape or something equivalent thereto is driven for a certain period every certain period of the response tape. Needless to say, it is applicable to all. As described above, in the present application, as seen in previous applications, the reproduction of the reception tape during remote control was continued using the time of one section (one round) of the response tape itself, rather than using a timer. a' Compared to the previous application, the main timer can be omitted, which saves cost, and 'b - Since the T-2 travel is controlled by one round of the response tape, the time is saved in the subordinate CR.
It is much more accurate than one controlled by a timer,
'c} To restore the device at the beginning of the response tape,
The applicant claims the patent as indicated in the above claims because it has various excellent practical effects, such as being able to wait for the next standby state while the tape is being started naturally. It is something.
