-15763 (Japanese Patent Application No. 49-96887) is a known example. The present application is an improvement on these conventional known examples. The first purpose of the present application is to emit a first remote control signal (hereinafter referred to as _f1 ) for the purpose of remotely listening to this device from a remote location, and transmitting a signal to a receiving tape T.

This is a sound generation circuit. Next, details of the operation will be specifically explained. First, we will discuss the case where a call is received from a third party (an unspecified number of people). When a ringing signal enters the terminals L1 and L2, it is detected by the ringing circuit 1 and in order to keep the load relay Y-1 in operation,
A loop is formed via the contact y1-1 and the primary side of the line transformer LT, and the calling signal is stopped. At the same time, the T-1 drive circuit is activated by the output of ringing circuit 1 .
3 is set, and the response tape T-1 is driven at a constant speed to drive the load motor M1. T here
-1 pre-recorded response terms are recorded in the recording/playback head.
The signal is reproduced by the RPH-1, amplified via the T-1 recording/reproducing circuit 4 , and sent to the line via the matching circuit 2 and line transformer LT. Next, when a pre-recorded beep tone is played following the response term, it is detected by the beep tone detection circuit 5 ,
This output sets the T-2 recording start circuit 6 , and the output drives the motor M2 at low speed to set the input terminal of the variable speed motor drive circuit 9 to H level via the OR gate G-1. do. When the motor M2 is driven at a low speed in this manner, the receiving tape T-2 is run at a normal constant speed. Also, the audio switch 7 is activated by the output of the T-2 recording activation circuit 6 . When a message from a third party comes in here, the line trans
LT, the signal is amplified by the T-2 recording/reproducing circuit 8 via the matching circuit 2 , and recorded onto the receiving tape T-2 by the recording/reproducing head RPH-2. Next, when the third party hangs up and the silent state continues, or when a dial tone or busy tone is sent from the station, the output of the audio switch 7 goes to H level.
This resets the ringing circuit 1 and the T-2 recording starting circuit 6 , so that the relay Y-1 is restored and the loop is opened, and the motor M2 is stopped to stop the running of the receiving tape T-2. Press to return to standby mode, waiting for the next call. Then, by repeating the above-described operation, messages from third parties are accumulated on the receiving tape T-2. In addition, response tape T-1
continues to run even during recording of the receiving tape T-2, and when the foil P-1 comes into contact with the electrode CP-1 after completing one circuit, the T-1 drive circuit 3 is reset.
-1 stops running. Next, we will discuss remote control operations performed by the owner using a telephone while away from home. When the device is called as described above, the response terms are first played back from T-1. When the remote control signal _f1 is sent here, it is detected by the filter circuit 11 via the line transformer LT and the matching circuit 2 , and the T-2 playback switching circuit 16 is set, and its output switches the T-2 recording and playback circuit. 8 to the receiving tape T-2 playback side, and control terminal CON of the T-1 recording/playback circuit 4 .
Through this, the amplification effect of this 4 is lost and the response term is prevented from being reproduced. Thereafter, the response tape T-1 runs silently on its own until it reaches the starting point. At the same time, the output of the filter circuit 11 instantaneously resets the tape counter 15 to "0000". This is because the counter 15 has a built-in solenoid in series with the capacitor, and this solenoid is instantaneously driven to reset the counter scale to "0000". At the same time, the output of the filter circuit 11 sets the unwinding circuit 14 , thereby driving the unwinding solenoid SD-R of the load. The output of 14 is passed through gate G-1 to set the input terminal of variable speed motor drive circuit 9 at H level to drive the load motor M2 at low speed. In this way, when the motor M2 is driven at a low speed and the rewinding solenoid is driven, the receiving tape T-2 is rewound at the normal rewinding speed. During this winding, the winding sound generating circuit 23 is driven by the output of the winding circuit 14 to generate an intermittent signal with a cycle of, for example, 2 seconds. As described later, this intermittent signal disappears when T-2 is rewound to the starting point, so by counting the number of these intermittent signals, the owner can determine how much T-2 has been rewound. It is possible to determine whether the same amount of messages have been stored in T-2. Now, during the above-mentioned rewinding, the rotary switch R-SW is connected to the reel stand (not shown).
Since this stops when T-2 is rewound to the starting point, the starting point detection circuit 17 detects this and sets its output to H level. This output resets the winding circuit 14 , so the solenoid SD-R, the winding sound generating circuit 23 , and the motor M2 that were driven by this output stop their operations, so T-2 remains stopped at the starting point. placed. At the same time, the alarm issuing circuit 1 is activated by the output of the starting point detection circuit 17.
8, and sends out an intermittent signal with a period of 1 second, for example, from its output OUT1. At the same time, its output
An H level signal is output from OUT2 and AND gates G-3 and G-2 are pulled up to H level.
Here, the owner receives the receiving tape T-2 as mentioned above.
It is determined whether to reproduce at high speed or low speed (standard constant speed), and remote control signal f ₂ or remote control signal f ₃ is selected and transmitted. For example, if you send the remote control signal f ₂ (for high-speed playback),
This signal passes through the filter circuit 12 and resets the alarm generation circuit 18 via the OR gate G-4, thereby stopping the intermittent signal, and further raises the AND gate G-3 to the H level. The output becomes H and T-2 high-speed regeneration circuit 1
9, and this output causes the motor M2, which had been temporarily stopped as described above, to maintain the high-speed input terminal of the variable speed motor drive circuit 9 at the H level.
Now drive at high speed. Here is the receiving tape T.
-2 is driven in the normal direction at a high speed (for example, four times the constant speed), and the recorded message from a third party is played back at, for example, four times the speed. Owners of remote locations can simply connect a high-speed recorder to their telephone handset and record it in less time (1/4 the time) than before, and listen to it later in a quiet location. It can be done. Now, the tape counter 15 is driven in the reverse direction during rewinding, but during playback it is driven in the forward direction and when it reaches the remote control point (the point where the remote control was first turned on), the scale of this counter becomes "0000". At this time, the built-in contacts are short-circuited, so the output terminal OUT becomes H level,
In order to reset the T-2 high-speed regeneration circuit 19 by this output, as is clear from the above, the motor M2
stops, and T-2 stops running. At the same time, a timer 21 is driven by the output of the counter 15 , and when the output terminal OUT1 is at H level for, for example, 10 seconds, the remote control point display signal generation circuit 22 is driven during that time to send out, for example, a continuous signal. Once the owner hears this signal on the monitor of a recorder coupled to the handset, he can hang up. On the other hand, after 10 seconds, the output terminal OUT2 of the timer 21 becomes H level, and this signal resets the ringing circuit 1 by restoring the relay Y-1 and opening the loop. At the same time, in order to reset the T-2 regeneration switching circuit by the output of OUT2 of this timer 21 ,
At this point, the device returns to a complete standby state. On the other hand, when the remote control signal _f3 is sent out while the T-2 is stopped at the starting point, the output of the filter circuit 13 sets the T-2 low-speed reproduction circuit 20 via the AND gate G-2, and further this output is Since the low speed input terminal of the variable speed motor drive circuit is held at H level through OR gate G-1, T
-2 will be played back at low speed. In this case as well, as in the case of high-speed playback described above, when the remote controller point is reached, the counter 15 stops T-2, and the timer 21
The device will recover after 10 seconds. As described above, when the owner rewinds a tape at high speed by remote control from a remote location, the owner takes into account the time required to rewind the tape and, conversely, the time required to play it back at normal speed. If time is not required or if it is convenient for the owner to listen directly, the remote control signal f ₃ can be sent out and played back at normal speed for direct listening, and from the rewinding sound. If it takes time to think about the playback and calls are costly, or if you don't have much time to listen, you can send out another remote control signal _f2 and record it on a high-speed recorder that you carry separately. Once the information is received, the owner listens to it slowly and can make any of the above selections according to his or her will, which increases the practical effects of this type of device. It can be done.
