Description

[Detailed Description of the Invention] This invention relates to a device mainly used for repetitive information notification in telephone services such as weather forecasts and market price notifications, which repeatedly reproduces an endless magnetic tape and sends this reproduced signal to a central office line. The present invention relates to a talkie sound source device designed to perform the following functions.

This type of talkie sound source device is equipped with two systems of reproducing sections, and when one system breaks down, it is automatically switched to the other system so that the signal transmission to the central office line is not cut off.

In this case, it is necessary to prepare two magnetic tapes with the same message recorded on them, and instead of using a scale that is very troublesome when recording, even if the recorded tapes are to be sent to a remote location, two magnetic tapes must be prepared. It has the disadvantage of being uneconomical as it has to be sent to the same address.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks.
To provide a talkie sound source device which can ensure the integrity of continued playback by operating another system when one system fails by simply preparing one recorded tape.

AL and BL are contacts activated by the audio detection circuit 8.

The main control device 9 is configured so that the A system starts playing by pressing the start switch STa, and when the sound of the A system is no longer detected by the audio detection circuit 8, the B system, which will be described later, starts playing. There is.

Next, 10 is a recording control device, in which A2
, A3, A4, and A5 are relays.

This is a contact operated by a relay, which is indicated by the symbol A followed by a second number.

Sensors 12a and 13a are in contact with the magnetic tape 2a, and are activated by contacting a sensing tape (made of an electrical conductor) attached to the magnetic tape 2a. 12a and 13a can be electrically connected to each other.

Next, the portion related to the recording function in the A system 1a will be explained.

paO is a switch connected to the output terminal 3"a of the magnetic head 3a, and is designed to switch to either ground or the input terminal 4"a of the amplifier 4a.

The switches paO, pa1 and the switch pa2 in the recording control device 10 are connected and disconnected in conjunction with a lock switch Pa (not shown), and by pressing this lock switch Pa, the A system 1
A has a recording function added to enable recording.

Next, in the description of the B-system reproducing device (also simply referred to as B-system), redundant explanation will be omitted by replacing A and B and a and b in the above description.

In addition, in the main controller 9, the start switch STb
When pressed, A and B in the explanation of the main control device 9,
Let us respond by switching a and b.

Next, 14a is a recording circuit 14b which connects the output terminal 4'a and the input terminal 1lb.
This is a recording circuit that is connected to the

With the above configuration, A system 1a is regenerated, B system M
The case where a playback signal is recorded to 1b will be explained.

First, it is assumed that a message is recorded on the magnetic tape 2a immediately after the sensing tape portion.

When the start switch STa is pressed in the state shown in FIG. 1, the relay A1 is activated and the contact a01 is brought into contact and self-maintained.

At the same time, the contact a12 is connected, so the motor 5a rotates, the magnetic tape 2a runs, and the message is picked up by the magnetic head 3a and passed through the switch paO to the amplifier 4a.
The signal is amplified in width and sent to the central office line 7 via the line transformer 6 through the contact a13.

The message being played back is transferred to the magnetic tape 2 of B system 1b.
When a lock switch Pb (not shown) is turned on in order to record data to the recorder B, the switches pbo, pb1, pb2 are switched from the state shown in the figure to the opposite side.

As a result, the B system 1b becomes ready for recording.

The sensing tape in the magnetic tape 2b is the sensor 1
2b and 13b are not in a conductive state (at this time, the magnetic tape 2b is said to be at the sensing position), relay B2 is in the recovery state, and contact b20 is in the state shown (recovery side), and relay B3 is in the state shown (recovery side). is activated, the contact b31 is connected, the motor 5b rotates, and the tape 2b runs.

When the magnetic tape 2b comes to the sensing position, the sensor 12
b, 13b conduct, relay B2 operates, and contact b20
becomes active, relay B3 is restored, contact b31 is disconnected, and magnetic tape 2b is stopped.

On the other hand, the magnetic tape 2a continues to run, and when it reaches the sensing position, the sensors 12a and 13a become conductive and the relay A2 is activated.

At this time, the magnetic tapes 2a and 2b are both at the sensing position, and IJL-A2 and B2 are operating.

Therefore, since contacts a22 and b22 are in contact, relay B4 is activated and contact b40 is in contact, relay B3 is activated and contact b31 is in contact, motor 5b is driven, and magnetic tape 2b runs.

The previous relay B4 is self-held by contact b41.

Since the contacts b23 and b42 are connected, the relay B5 also operates and maintains itself.

In this state, when the magnetic tape 2b passes the sensing position, the relay B2 is restored and the contact b23 is disconnected, but the relay B5 is self-holding.

The magnetic tapes 2a and 2b are now running together.

The reproduced message signal is sent to the output terminal 4' of the amplifier 4a.
a to the input terminal 1lb via the recording line 14a,
The switch pbO enters the magnetic head 3b through the resistor Rb.
is grounded through.

The data is now recorded on the magnetic tape 2b. When magnetic tape 2b comes to the sensing position, sensors 12b and 13b become conductive, relay B2 is activated, contact b20 is activated, and contact b50 is disconnected, so relay B3 is restored and motor 5 is activated.
b stops.

Now the message on magnetic tape 2a is transferred to magnetic tape 2b.
It was reproduced in .

The A-system reproducing device 1a continues to send messages to the central office line 7.

After that, if lock switch Pb is turned off manually or automatically, relays B4 and B5 are restored.

If the A system playback device 1a fails, the audio detection circuit 8
is activated, the contacts AL and BL in the main controller 9 are switched, the B-system reproducing device 1b starts reproducing, and the reproducing signal is transmitted from the output terminal 3'a of the magnetic head 3b to the amplifier 4b via the switch pbo. The signal is amplified in width and sent from the line transformer 6 to the central office line 7 through the contact bl3.

Therefore, messages continue to be sent despite the failure of the A line 1a.

In the above explanation, the A system 1a is first reproduced and the B system 1b is reproduced, but conversely, the B system 1b is reproduced and the A system 1 is reproduced.
It is also possible to copy to a.

The operation in this case is explained above by replacing the symbols A and B, and a and b among the symbols of the part names, so that they are easy to read and redundant explanations are omitted.

As described above, according to the present invention, even when the A system 1a fails, the B system 1b can be activated to continue sending the signal to the central office line 7, and in accordance with this, the reproduction of the recorded touch message can be continued. This has the effect of ensuring maintainability.

Moreover, a recording function is added to the B system a1b, and the A system a1
A recording line 14a is provided so as to input the output of A to the recording line 14a, and during playback of the A system 1a, the sensing tape portions of the endless magnetic tapes 2a and 2b of both systems are detected by sensors 12a, 13a, 12b, and 13b. The magnetic tape 2b of the B system 1b is used for one cycle from 1 to detection again.
Since the recording control device 10 is provided so that the message is recorded on the A-line 1a, the message content can be automatically copied to the B-line magnetic tape 2b when the A-line 1a is played back.

This has the great advantage that only one magnetic tape is required on which the message is recorded, although the above-mentioned integrity can be guaranteed.
