Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables a remote listening answering machine to send any message as soon as possible when the user calls from a remote location using a pre-recorded customer call tone. It concerns a device that picks up and listens to the sound. Previously, there were structures similar to this, but none of them were perfect.
In short, there was no other option than to play the tapes one after the other and wait for the desired one to appear. An object of the present invention is to enable a user who is away from home to instantly send any message by specifying the code number, as long as he remembers the code number assigned to the message.

The structure and operation of the embodiment of the present invention will be explained below.

FIG. 1 is a circuit diagram showing the principle of the present invention,
FIG. 2 illustrates the recording state of the receiving tape T-2.

In Figure 1, L1 and L2 are telephone lines, LT
is a line transformer that connects the telephone line and this device, T-1 is an endless response tape inscribed with application terms, P-1 is a conductive foil pasted to the starting point of T-1, and CP- 1 is a starting point detection electrode short-circuited by P-1, EH-1 and
RPH-1 is an erasing head and recording/reproducing head for T-1. As shown in Figure 2, T-2 is a receiving tape consisting of two tracks, EH-2 is an erasing head that is shared by the first and second tracks of T-2, and RPH-2-1 is a receiving tape of T-2. The recording/playback head for the first track, RPH-2-2, is the head for the second track of T-2. Further, 1 is a ringing amplifier that maintains the load relay Y-1 in an operating state when a ringing signal is detected, and the reset terminal R is set to H.
This hold is released when the level is reached. Also 2
is a start point detection circuit for detecting the start point of the above T-2, 3 is a clock for the CPU which will be described later, and 4 is a start point detection circuit for detecting the start point of the above T-2.
-1 is a motor drive circuit for the drive motor M1, and 5 is a motor speed control circuit for the above-mentioned T-2 drive motor M2. When the terminal LS is at H level, M2 is driven at the normal speed, and the terminal HS is M2 at H level
It is constructed so that it can be driven at high speed. Further, 6 is a solenoid drive circuit for driving the solenoid SD2, and when SD2 is driven while the above-mentioned M2 is being driven at a normal speed, the above-mentioned T-
2 is driven in the forward direction at a constant speed, and when SD2 is driven with the above M2 being driven at high speed, T
-2 is fast forwarded at a constant high speed. 7 is a drive circuit for the solenoid SDR, and when SDR is driven while M2 is being driven at high speed, T
-2 is rewound at a constant high speed. Also, the CPU is a microprocessor, ROM
is read-only memory where programs are stored, and RAM is random access memory where data is temporarily stored. In the diagram, the CPU, ROM, and RAM are separated, but
It goes without saying that a single-chip CPU integrated into one may also be used. Further, IC-1 to IC-5 are analog switches through which signals pass in the direction of the arrow when the control terminal C becomes H level. Also, PLL1 to PLL7
is a PLL circuit for detecting a specific frequency, PLL1 is for detecting the 400Hz signal sent from the station, and PLL2 is for detecting the end tone recorded at the end of each message on the first track of T-2. PLL3 to PLL7 are for detecting signals of the pushphone (registered trademark).

Further, FIG. 2 illustrates the recording state of the above-mentioned receiving tape T-2, where 10 is the first track, 11 is the second track, 12 and 13 are the recorded messages from the calling party, and 14 is the recorded state of the receiving tape T-2. and 15 are end tones recorded after the message from the calling party is finished, and this is used as a signal to determine the end of each message. Also, 16 and 17 are signals indicating the code number, 16
17 indicates that one pulse is recorded and is the first message, and 17 indicates that two pulses are recorded and is the second message.

The present invention is composed of the above-mentioned parts and has the following functions. First, when this device detects an incoming telephone signal, the input port 1 of the CPU changes from H to L through the ringing amplifier 1.
The program built into the ROM will start. Next, the output port 13 is set to H and the motor M1 is operated via the motor drive circuit 4 to drive T-1 in the direction of the arrow. At the same time, set output port 2 to H.
IC-1 is connected and RPH-1's re-output sound is AMP-1
The signal is amplified and sent out via the line transformer LT. When T-1 goes around once and the conductor foil P-1 comes into contact with CP-1, this is detected through the input port 2, and the motor M1, that is, T-1 is stopped, and at the same time, a beep tone is sent out through the output port 1. After sending out the beep tone, the output port 11 is set to H, and the motor M2 is driven via the motor speed control circuit 5, and at the same time, the solenoid SD2 is driven via the output port 9, so that T-2 is normally fed. At the same time, output port 7 is set to H, so the recording amplifier AMP-4 is connected to the recording/playback head RPH-2-1, and the caller's voice is output to T.
-2, record on the first track as shown in Figure 2, 12. When T-2 starts as described above, one pulse (because it is the first incoming call) is sent from output port 6 to the second track of T-2 via AMP-3 and IC-4 as shown in Figure 2. It was recorded as 16 of
Also, the first incoming call is recorded in the RAM. When the caller hangs up and a 400 Hz tone is input from the office, this is detected by PLL 1, and output port 13 is set to H via input port 3 to restore relay Y-1 and open the loop. Next, output an end tone of a specific frequency from output port 1,
1 of T-2 via resistors R4, R2 and AMP-4.
At the end of the cycle, the end tone is recorded for a predetermined period of time as shown at 14 in FIG. 2, and then the complete standby state is restored. Repeat the above operation for each incoming call,
The number of incoming calls is stored in RAM.

Next, to start the remote control, use the pushphone (registered trademark) or if there is no pushphone.
If you send a specific code, such as a 418# PIN number, from a portable signal generator that replaces a pushphone,
This is detected by PLL3 to PLL7, and a reproducing circuit for the recording/reproducing head RPH-2-1 of the first track is formed via IC-2 and AMP-1, which are turned on with output port 3 set to H. At the same time, output port 4 is set to H, and the output of RPH-2-2 of the second track is connected to input port 10 via IC-3 and AMP-2, which are turned on. At the same time, the output port 12 is set to H to drive the motor M2 at high speed via the motor speed control circuit 5, and the solenoid is driven via the output port 10.
Since it drives SDR, T-2 is rewound at high speed. At this time, in the first remote control operation, T-2 is turned back to the starting point. When the starting point is detected via the starting point detection circuit 2, the output port 10 is set to L via the input port 11 to release the solenoid SDR, and at the same time, the output port 9 is set to H to drive the solenoid SD2. At the same time, the output port 12 is set to L and the output port 11 is set to H to drive the motor M2 at low speed. At this point, the receiving tape T-2 is switched from rewinding to normal playback. During this remote control playback, the code number (16, 17 in Figure 2) of the second track of T-2 is checked, and the code number matches the number of incoming calls stored in the RAM, and the end tone is detected. The program stops T-2 from running. If a predetermined period of time continues, the output port 13 becomes H and returns to the standby state. If you specify a code number during remote control playback or while T-2 is stopped as described above, for example, for the third message, press 3# to quickly rewind T-2 and input the code number. When detected, normal feeding occurs, and when an end tone is detected at that end, output port 12 becomes H.
Since the motor M2 is driven at high speed, T-2 is fast-forwarded and returns to the standby state after detecting the last code number. When the next remote control is operated, T-2 is rewound to the code number that matches the previous number of incoming calls stored in the RAM, and then the playback is switched to.

As described above, in the present invention, a code number is attached to each message recorded by an unspecified number of customers (callers), and a user calls the message from the outside and sends the code number to the Pushphone (registered trademark). By specifying the message with the # symbol and a number, the message corresponding to the code number corresponding to that number can be immediately called up. This method has a much more practical effect than the one in which the tape had to be played back one by one from the starting point and then waited.
