Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a device for informing a caller by voice of the number of incoming calls in an answering machine.

In Patent No. 91511y (Japanese Patent Publication No. 46-47-6 filed by the same applicant), the applicant proposes a device that automatically answers telephone calls and allows the user to listen to the telephone calls from a remote location. This proposed a method that would let you know how many calls had been received by emitting a sound pulse equal to the number of calls that had been accumulated up to that point when remote listening was started in the middle of a response tape. However, this method is inconvenient because the number of pulses cannot be determined unless the pulses are accurately taught. In this application, the number of times is uttered accurately using voice. In other words, the purpose of the present application is to store the number of incoming calls that have been accumulated while the answering machine is away from a microcomputer in a RAM, and then the owner can remotely control the number of calls that have been received by an answering machine, thereby converting the number of incoming calls into a voice conversion device. The goal is to convert the information into audio and inform the user.

A second object of the present invention is to make it possible to operate only the response tape without counting the number of incoming calls at the end of the tape, and not to count this count as the number of incoming calls. The third purpose of the present application is to clear the memory of the microcomputer, RAM, and other devices in order to return the number of incoming calls to the first one after knowing the number of incoming calls using the remote control as described above. The structure of an embodiment of the present application will be explained below. In the figure, LT is a line transformer for connecting this device to the telephone line, 1 is an incoming call detection circuit using a photocoupler or the like to detect a calling signal, and 2 is a startup circuit that introduces the output of the above incoming call detection circuit 1. It consists of an integrating circuit that accumulates charge, and a Schmitt circuit that outputs an output when this charge reaches a certain value.

3 is a holding circuit using a flip-flop circuit;
is a relay, and yl-1 is its contact. Further, 5 is an amplifier circuit for amplifying the remote control signal, 6 is a microfork for detecting the remote control signal, and 7 is the 6 above.
8 is a buffer circuit for improving the rise of the output of 6, and 9 is a read-only memory ROM, the contents of which are data for generating sounds from 0 to 9. - has been memorized.
10 is a drive circuit for the motor MI for driving the response tape T-1, and 11 is an audio control circuit VOX, which maintains its output by the incoming audio after the device switches to the recording state. This is a common voice control circuit that has a function such that if a silent tone, dial tone, or busy tone other than voice is input continuously for several seconds, the output disappears. Further, 12 is a motor drive circuit for driving the motor M2 for receiving tape T-2, and 13 is a motor driving circuit for driving the pinch roller PR-2 to drive the tape T-2.
A solenoid disturbance circuit 14 that drives the solenoid coil SD for crimping to P-2 repeatedly opens and closes via a reel stand (not shown) while the receiving tape T-2 is running. This rotary switch stops opening and closing when T-2 travels to the end or is rewound to the starting point. In addition, 15 is LPC (Lima "Pr
This is a speech synthesizer based on the CMing method, and is processed by a microprocessor CPU.
16 is a D-A converter for converting the digital output of the voice synthesizer 15 (false 1) into analog; IT is an amplifier circuit; Power amplifies the beep tone signal output from 2. Further, T-1 is an endless response tape, and a conductive foil P-1 is pasted at the starting point, and has an electrode CP-1 for detecting the conductive foil P-1. Also C
The PU is a one-chip microprocessor that handles the entire process of book counterfeiting, and the R
It has a built-in OM and a RAM for temporary storage.

18 is a clock circuit for the CPU, which uses a crystal. The above-mentioned parts constitute this device. Next, the effect of the present application will be described. First, when there is an incoming call from a third party, it is detected by the incoming call detection circuit 1, and the relay Y-1 of 4 is driven via the starting circuit 2 and the holding circuit 3, and the telephone line is closed via its contacts y1-1. Form a connection circuit.

At the same time, the output of the starting circuit 2 enters the input port 3 of the CPU to start the CPU. First, the output port 3 of the CPU becomes "H" and the motor MI is driven via the motor drive circuit 10 to run the response tape T-1. child)
The response term recorded on T-1 is the playback head RPH.
-1 and sent out to the line via LT, but this circuit is omitted because it is a public 3 mark. T-
1 tape goes around once and the foil P-1 on the T-1 tape becomes the electrode C.
When P-1 is touched, the output port 3 is set to "L" by the program via the input port 4, and the motor drive circuit 10 stops the motor MI and the tape T-1. Next, the program sends out an audible signal of about 0.9 Sunama beep tone from the output boat 2 to inform the third party that Hitomi Motobishi is switching to recording mode, but this is caused by the program's clock signal of the clock circuit 18. is converted into a flexible signal. Subsequently, output port 4 becomes “H” and VOX circuit 1
1, the motor drive circuit 12 is started via this VOX circuit, and the motor M2 is further driven. Subsequently, the solenoid drive circuit 13 is activated via the output boat 6, energizing the solenoid SD, and thereby the pinch roller P
With R-2 pressed against the capstan CAP-2, the receiving tape T-2 runs in the normal feeding direction in a recording state. Subsequently, the output boat 2 sends out the 0.9 sand beeb tone again. This beeptone is sent from the line transformer LT to L1 and L2 via the amplifier 17, but this beeptone is also recorded on T-2 and used to determine the end of messages from a third party. . However, since the recording circuit is well known, it is omitted in this figure. Inside the CPU, when the recording state is switched to as described above, the fact that there was a single incoming call is stored in the 8-bit RAM used as a built-in counter.

This is incremented (added) by 11 when the T-2 tape is switched to the recording state for each incoming call. The reason why T-2 was made to increment after switching to the recording state was T-2.
If 12 is recorded to the end, this type of answering machine usually works as an answer-only machine, so it is meaningless to count the number of incoming calls when it works as an answer-only machine. I try not to do that. Now, the recording of T-2 is maintained through the VOX circuit 11, but if a third party hangs up the phone and says, ``It will be in a state of silence, or if the station sends a signal tone such as a lockout loan, after a few seconds.'' Since the output of the VOX circuit 1 1 becomes "L", the motor M2 is stopped via the motor drive circuit 12, and then the input board 5 detects that the output of the VOX circuit 1 1 becomes "L", and this Return the CPU to its initial state using a program.

Therefore, the output boat 6 is
is turned off and T-2 stops running. At the same time, the output port 1 becomes "L" and the holding circuit 3 is reset, so the relay Y-1 of 4 is turned off and the loop is opened, so that the device returns to the standby state. Next, the remote control operation performed by the user from outside will be described. If you call the book bag counterfeit and send a remote control signal while the response tape T-1 is being played, the micro fork M of the line transformer LT and amplifier circuits 5 and 6 will be activated.
, the rectifying and smoothing circuit 7, and the buffer circuit 8 to pull the input port 2 to "H". As a result, the CPU side determines that a remote control signal has been received. First, output boat 7
Although not shown in the figure, by making rH [one, T-1
The reproduction sound of T-1 is turned off, T-1 continues to run silently, and the amplifier circuit of T-2 is put into reproduction mode. T-1
If the playback sound stops midway, confirm that the remote control is working properly, then turn off the remote control signal. When the CPU determines via the input board 2 that the remote control signal has been cut off, the voice call arrival count notification device of the present invention, which notifies the number of call arrivals by voice, is activated. First of all, the CPU is C
It is checked how many count values are stored in the 8-bit RAM in the PU for each incoming call.

For example, if the number of incoming calls is 15, this is a decimal number, so it is normally stored in RAM as a "value" equivalent to hexadecimal, but with this device, the number of 1G ships is directly stored by the program. The number of incoming calls is memorized. That is, in the above example, it is "15". Therefore, the maximum value in this embodiment is up to "99" in terms of IQ Hayabusa, which is sufficient for practical use in an answering machine. Now, if the count value is "15" above, the upper digits (this is the upper 4 of the 8-bit RAM)
If it is determined to be ``1'', it is checked as ``1'' in the ROM where the audio data is stored.
The range in which audio data corresponding to
U sequentially outputs corresponding audio data while giving instructions via the address bus. Approximately 120 ITs are allocated to each number from 0 to 9, and approximately 1 second is required to output the data for each number.

Now, data 1 of the above is added to the voice synthesizer 15 via the output port 8, but in this case, even if the ROM capacity is small, LPC (LimarPre
A process of predicting linearity is performed using a dictation coding method. This method is already known for use in speech synthesis devices such as those manufactured by Texas Instruments. Since the output of the voice synthesizer 15 is a digital signal, it is converted to an analog signal via a DA converter 16, amplified by an amplifier circuit 17, and then sent to the line via the LT. child)
So, the data that makes "1" sound like "one" is in the ROM.
is stored in When the CPU determines that this "1" data has been sent from the above end address, it then reads the "1" data stored in the lower 4 bits of the RAM.
5" is processed in the same way as "1" above. This “5”
sounds like "Five". In other words, the number of incoming calls "15" ultimately sounds like "one five five." If this were to be uttered as "fiftine," a huge ROM capacity would be required for the numerical values 0 to 99, which would be extremely expensive, so this method is used in the present invention. Furthermore, if the number of incoming calls is five, the program can be used to make it pronounce "FIVE" or "ZERO FIVE". When the CPU determines that the utterance of the number of incoming calls as described above has ended, the output port 5 becomes "H" according to the program, and rewinding of T-2 is started to drive the motor M2 via the motor drive circuit 12.

This is because T-2 is driven only by the motor and serves as a winding mechanism when the solenoid coil SD does not work. During this rewinding, the rotary switch 14 linked to the reel stand (not shown) repeats opening and closing, thereby causing the input boat 6 to
Repeat H and "L" to check that rewinding is continuing. When the T-2 is wound back to the starting point, the input boat 6 remains at "H" or "L" depending on how the rotary switch 14 stops. At this point, the CPU determines the end of rewinding, and drives the SD via the solenoid drive circuit 13 to set the output port 6 to "H", thereby lowering the receiving tape T-mount 2.
Switch to normal feed. In this step, the user can sequentially listen to the messages from the customer previously recorded on T-2. Next, in order to release the remote control, the owner sends the remote control signal again, and the input boat 2
”, the CPU is reset to the initial state by the program, and therefore the counter RA
M is also reset to "00", stopping T-2 from running and opening the loop. Therefore, when the next call arrives, the counter RAM will count from "01". In this embodiment, the system is configured so that the incoming message is heard when it is quiet after the remote control signal is turned off, but it is possible to listen to the incoming message over the outgoing remote control signal as long as you pay attention to the signal level. Not even. As described above, in order to further perfect the device of the present invention, which achieved its general purpose in the aforementioned Hakama Kosho 46-47086, the present application uses a voice generation device consisting of a CPU and a voice synthesizer, and converts the numbers in which the voice is stored into a decimal system. Since it was configured to speak out one digit at a time as a number, it was possible to have the generation function with a relatively simple device such as a RAM for storing voice data or a voice generator. Since the counter is made to count when the receiving tape is driven, if the connection is released only by driving the response tape, or if the receiving tape reaches the end and the receiving tape is not driven, There is no counting, so that when you listen to this with a remote control, the counted number does not confuse with the actual number of incoming calls.

Also, by listening to the remote control once, the RAM and other memory bags are all cleared, and a new count is started from the next incoming call. Since such a device is unprecedented and extremely effective as a future direction, the applicant claims a patent within the scope described above.
