Further, reference numeral 5 denotes a ringer section, which amplifies the tone ringer through a piezoelectric element speaker 6 into which a calling signal is received.

Note that H8I and H82 are hook switches.

As mentioned above, although only the main parts of the multifunction telephone are shown in Figure 1, the DTMF tones generated by pressing the dial keys are for calling the called party, and this telephone has a built-in It is not intended to control the equipment being used.

On the other hand, in Fig. 2 of the subject, various operations can be performed on the equipment built into the telephone by key operations on the dial keys, and the above equipment is operated by remote control using a telephone outside the home (Pussiniphone). It is configured so that it can be executed using the same operating method as when operating at home.

Note that although this embodiment is described using tape as the recording medium, the present invention is not limited to tape (it can also be used with a solid-state recording/playback circuit using RAM (random access memory)). In this case, components that require electric power, such as the solenoid and motor described above, are not required, and control with reduced power consumption is possible.

Next, detailed operation will be explained.

In one embodiment of the present application, an answering machine is shown in a telephone as shown in FIG.

This basic circuit was developed in Japanese Patent Application Laid-Open No. 60-23 by the applicant.
0754, and in these earlier applications, the buffers G-1, G-2, and G shown in FIG.
Operation button (t1) on the input side of -3, (AUTO)
, (t-2) are connected, and the above operation button (t-2) is connected.
1") once, the response tape will be fed normally; if pressed twice within a certain period of time, the response tape will be rewound; and if pressed three times within a certain period of time, the response tape will be fed normally. Fast forward.To control the receiving tape,
The operation key (t-2) is pressed, but normal feeding, winding, and fast forwarding are the same as in the case of the response tape described above.

In addition, in order to drive the response tape or reception tape in recording mode, press the operation button (AUTO) once and then press the operation key (t-1) within a certain period of time, for example, 1.5 seconds.
) or (t-2) once.

In order to put the automatic answer recording into a standby state, press the operation button (AUTO) once as described above and leave it as it is, and the machine will go into a standby state waiting for an incoming call after 1.5 seconds as described above.

Also, if you press the operation button (AUTO) once and then press the operation button (t-1) or (t-2) two or three times consecutively within the above specified time, the corresponding tape will be rewound. Erase in state or fast forward state.

Also, press the corresponding operation button 1 to cancel the above operation.
Press twice.

In the previous application, the various operations described above were performed using three operation buttons (t-1).
, (AUTO), and (t-2).

On the other hand, in the present application, the dedicated operation button (t-
1), (AUTO), and (t-2) are omitted and are used in common with the dial key for dialing on a telephone.

In this embodiment, the operation buttons corresponding to the above (t-1) are the 1'' key of the dial key 21 shown in FIG.
(AUTO) corresponds to the 2'' key pressure, and (t-2') corresponds to the 3# key pressure.

We will explain manual operations while at home.

Note that this manual operation has been described in detail in the above-mentioned earlier application based on a flowchart, so the flowchart will be omitted here and the differences from the earlier application will be explained in detail.

First, when the power is turned on to this apparatus, it is assumed that the response tape (not shown) and the reception tape (not shown) are stopped. It is also assumed that the handset (not shown) of telephone 20 is in an on-hook state.

For example, in order to send the response tape normally,
Before the operation, if the PIN switch SW2 is on, the digital switch 32 is set to 3.
A digit password, for example 123'', is input by operating the dial key 21.

This PIN number is the same as the PIN number for remote operation, which will be described later, and can only be purchased by the owner of this device. If the PIN switch SW2 is turned on, a third party can use this phone. Even if an erroneous operation is made when making a call using a borrowed telephone, malfunction of the answering machine in the telephone or eavesdropping can be prevented.

Now, in order to normally feed the response tape from the stopped state of the apparatus as described above, after sending the password as described above, the It l jj key of the dial key 21 is pressed once. By pressing this key, the universal (7) DTMF oscillation circuit outputs two frequencies of 697H2 and 1209Hz,
After setting the level to an appropriate level with resistor R21, the amplifier circuit 2
4, and its output is applied to the tone decoder 25. The tone decoder section 25 is a tone decoder IC and a gate IC.

It is composed of a 3-state buffer to prevent the output from the speech recognition unit 33, which will be described later, from being confused.
When the switch SW1 is sliding to the left as shown, the output of the tone decoder section is activated. Therefore, while the tone decoder section is being applied with a DTMF of 1", the output/terminal (1) of the tone decoder section 25 is
It outputs an H level signal from , and interrupts the CPU via G-4. At the same time, the output from the buffer a is checked to see how many times the input terminal DBO becomes H level within one second (described later). If the above input terminal DBO becomes H level once, the output port P
Solenoid FWD, SD with 20 and P22 at H level
I and motor M1 are energized, and the response tape is normally fed.

In addition, if the input terminal DBO becomes H level twice within a predetermined time, the response tape is rewound three times or three times.
If the level reaches H level more than once, fast forwarding is performed.

On the other hand, if the key 3'' on the dial key 21 is pressed, the DTMF oscillation circuit 22 will output 697Hz and 147Hz.
Two frequencies of 7 Hz are output, amplified by the amplifier circuit 24, and the output terminal (3) of the tone decoder section 25 is raised to H level. Therefore, this output causes C to be passed through buffer G-3.
Pull the input terminal DB2 of the PU to the H level, and raise it to the H level several times within a certain period of time, as in the case of the input terminal DBO described above.
It checks whether the level has been reached, and based on this, the receiving tape is controlled to be normally forwarded, rewound, and fast forwarded.

Note that the above-mentioned constant time of 1 second is initialized every time a key of the dial key 21 is pressed, and 1 second is newly set to make the operation easier.

This also applies to remote control operations, which will be described later.

On the other hand, when the 12" key of the dial key 21 is pressed, the DTMF oscillation circuit 22 generates 697H2 and 13a.
It outputs two frequencies of isHz and raises the output terminal (2) of the tone decoder section 25 to H level via the amplifier circuit 24. Therefore, the input terminal D of the CPU is connected via the buffer G-2.
When BI becomes H level, the light emitting diode 32 (AUTo) blinks for 1.5 seconds according to the program. Alternatively, an intermittent sound is output from the output port P27, and the intermittent sound is amplified by the speaker SP via the analog switch G-14 and the amplifier circuit 3,0.31.

Now, as mentioned above, if you press the "'1" key on the dial key 21 once while the light emitting diode is blinking, the response tape will be in the recording state as in the previous application.
Press the I key once to enter the receiving tape recording state.

Also, as in the previous application, by pressing the at l pp, '3'' key a predetermined number of times, the corresponding tape can be rewound and erased.
Can be fast forwarded and erased.

On the other hand, as mentioned above, the light emitting diode 32 (AUTo)
Even if it is blinking, if you leave it as it is, it will go into standby mode in automatic response recording mode as in the previous application. At this time, the light emitting diode 32 does not light up continuously, indicating that the state has been switched to the standby state.

At the same time, the response tape is rewound for cueing, and when cueing is completed, the light emitting diode 33 (READY) lights up.

When a predetermined period of time (for example, 30 seconds) has elapsed after entering the standby state as described above or after the response tape or reception tape has stopped, the input of the above-mentioned PIN code will be canceled, and when performing the next operation, The password code must be entered again using the dial key 21.

Next, the operation in automatic response recording mode will be explained.

First, when an incoming call is received in the standby state, a ringing signal is detected by the ringing circuit 26 and sent to the C through the OR gate G-5.
It is input to the input terminal T'ESTI of PU. TES
T' 1 is connected to the counter in the CPU,
The number of alternating current waveforms of the calling signal is counted, and when it is regarded as a calling signal, output port P26 is set to H level, relay Y-1 is kept on, and the telephone line is closed via its contact y1-1. Make it.

Therefore, the ringing signal stops ringing and becomes a talking state. At the same time, output boats P20 and P22 are set to H level solenoid FWD.
, SDI and motor M1 are energized, and the response tape (not shown) is driven normally.

The response message is played back by the recording/playback head RPH-1,
Switching circuit 29, preamplifier 30. Analog switch G-
13 (programmed on) to the line transformer LT and is sent to the caller.

When the sending of the response message is finished, a DTMF (it l 71) tone is briefly recorded at the end of the response message.
When this DTMF tone is detected by the CPU via the line transformer LT, resistor R22, amplifier circuit 24, and tone decoder 25, the response tape stops running and the receiving tape (not shown) is detected by the CPU. ) in recording mode.

Therefore, the caller's message is sent to Line Translator LT.
Analog switch G-14 (turned on by program),
The recording/playback head RPH is connected via the preamplifier 30 and the switching circuit 29 (switched to recording mode by the program).
-2 and is recorded on the receiving tape.

When the caller finishes the call and hangs up the phone, the line voltage fluctuates, which is transferred to the ringing circuit 26.
When detected by CPU via OR gate G-5, relay Y
-1 is turned off to disconnect the telephone line. At the same time, the receiving tape stops running, the response tape is rewound to find the beginning, and the standby state is restored.

Next, we will discuss remote control operation by the owner who is away from home. Therefore, call this device using a touch-tone phone while you are away.

While the response message is being sent or after the receiving tape is switched to the recording state, the three-digit password set by the digital switch 32 is sent by pressing the button on the button 7.

If the passwords do not match, the device will recover, but if they match, the running response tape or reception tape will stop and wait for a remote control signal for the next operation.

The subsequent remote control operation is the same as the manual operation at home described above, and the key arrangement is also the same. That is, in order to listen to the message recorded on the reception tape, it is first necessary to rewind the reception tape, and to do so, press the "3" key on the touch-tone phone twice in succession. . This suppression causes the receiving tape to be rewound to the physical beginning or to the beginning of the unheard message. When the receiving tape is rewound to the starting point, it stops. Also, if you want to cancel the rewinding of the receiving tape, press the 3" key on the Poon-Phone once.

To play the reception tape, press the 3'' key on the touch phone once after the reception tape has stopped as described above.

To cancel playback of this reception tape, press the 3" key once. Or press the C button at the last end of the message.
It may be stored in the memory in the PU and automatically stopped at this point.

To switch to recording, press “2” on the touch-tone phone.
Press the key once. In the case of the manual operation described above, the light emitting diode 32 blinked, but when operating this remote control, the C
An intermittent sound is output from the PU output port P27 for 1.5 seconds. 61” on the touch-tone phone while hearing this intermittent tone.
Press the key once to switch to response tape recording mode and switch to part 3.
” key once to switch to reception tape recording mode.

In the response tape recording mode, the response message is dubbed, and in the reception tape recording mode, it can be used, for example, when you want to keep a record after listening to all the business messages remotely.

As mentioned above, in this embodiment, the
0754, but the present invention is not limited thereto. For example, the P1'' button on the touch phone can be used to play and stop a receiving tape, and the at3pp button can be used to play and stop a receiving tape. You can use the easy-to-operate keys on the dial key arrangement to perform functions such as backspace of the receiving tape, 7" button to record and stop the response message, and 9" button to play and stop the response message. It can also be used by assigning it to Of course, it goes without saying that the same function is assigned to the same key (button) K both during remote operation, which is the purpose of the present invention, and during operation at home.

As mentioned above, this device controls the devices inside the telephone using the push-on tone. However, since it would be inconvenient if the device inside the telephone malfunctioned due to the dial operation when calling the called party, countermeasures have been taken in the present application. That is, in FIG. 2, when the handset (not shown) of telephone 20 is picked up for dialing, hook switches H83 and H84 are closed. With this H83, the output of the DTMF oscillation circuit 22 that oscillates when the dial key 21 is operated is introduced into the output circuit 23, amplified by the output circuit 23, and then output to the telephone line.

On the other hand, since the input side of the amplifier circuit 24 is grounded by H84, the output of the DTMF is not input to the tone decoder section 25, so that the equipment in the telephone, in this embodiment the answering machine, will not malfunction.

However, in the above-mentioned example, when the called party is called and the conversation is started and the mutual conversation is to be recorded on the receiving tape, the DTMF tone is not input to the tone decoder 25 and it is impossible to control the receiving tape. It is possible.

Figure 4 shows an example of a circuit that solves the above problem.Dial operation for calling the other party (called party) from this device does not cause the device inside the telephone to operate, and when the called party answers, the call status is maintained. After this point, the above devices can be controlled by key operations on the touch-tone phone on the caller's or called party's side.

In FIG. 4 above, the circuits and components added to FIG. 2 are as follows.

That is, 34 is a line polarity reversal detection circuit, which switches the output OUT from H level to L level when the called party answers and the polarity of the telephone line is reversed to enter the talking state. This is a circuit that returns to H level when it goes on-hook. Various types of circuits using operational amplifiers, photocouplers, etc. are known as this circuit.

Further, TR, -1 is a transistor, and is turned on by the output of the line polarity reversal detection circuit 34 in cases other than the above-mentioned communication state.

Therefore, when you pick up the handset (not shown) to call the called party from this device, the hook switch H83,
84 is closed and the dial is being operated, the output of the line polarity reversal detection circuit 34 causes the transistor TR,-1 to
is on. Therefore closed hook switch H84
The input side of the amplifier circuit 24 is grounded through the ground.

Therefore, the DTMF tone generated by the dial operation does not reach the tone decoder section 25, and the equipment inside the telephone does not malfunction.

On the other hand, in a call state in which the called party answers and the output of the line polarity reversal detection circuit 34 changes from OFF to L level, the amplifier circuit 24 is activated and the transistor T-1 is turned off. A tone decoder 25 generates a DTMF tone by key operation of the caller or called party's touch-tone phone.
Since it reaches the CPU via the , it can control the devices inside the phone. Based on the same principle as above, even when a call is received and the call state is established, the above call is memorized, and from the time the called party goes off-hook to the time when the called party goes on-hook, that is, during the call state, both parties It is also possible to control devices within the stuffing machine by the operation. In addition, a dedicated recording button is provided in place of the above-mentioned Button 7 on key (numeric keypad), and this recording button operates only in the mutual call state as described above, so that the call state is canceled. You can also set this call recording to stop.

Next, the device has a speed dial section, which allows dialing numbers or codes for controlling internal telephone equipment to be stored in a memory within the CPU.

The above-mentioned code is, for example, a password code when starting remote control operation. In addition, in this embodiment, II I fit or u
The response tape or reception tape was controlled in various ways depending on the number of times the 3 jj button was pressed, but a special three-digit code similar to a PIN code was assigned to each type of control, and this special code was used to perform various remote control operations. Alternatively, it is also possible to perform a test.

Alternatively, in addition to the remote control operation described above, it is also possible to assign a special code for playing or recording a specific message. By storing this special code in the speed dial section, one-touch or two-touch operation of Button 7 on (dial key) is possible. It is also possible to use it for testing remote control operation or for actual operation.

In order to register the above-mentioned password code or special code in the speed dial section, the buttons of the dial button section 21 are pressed in the order of "x%YYY".

Here, ×” is a number representing the registration order using the keys 0 to 9.
For example, it is a 3-digit password code or special code where YYY is 0 to 9.

The program is the “Kaya” D that is generated by pressing the above key.
When a TMF tone is detected, the previously input number is regarded as a number representing a registration number, and the memory area in the CPU assigned to this number is specified by an address. Then, the three-digit number input after "Kaoru" is stored in the above memory area.

To read the code stored as described above, K presses the button "X", where "X" is the registration number described above.

When the program detects the DTMF tone "X", it specifies the memory address from the contents, reads the 3-digit code, and outputs it as a DTMF tone.

Alternatively, if ten buttons are provided on the input board (not shown) of the CPU, the speed dial can be read out with one touch.

The present invention can also be effectively used for cordless phones. In a conventional cordless phone, a base unit and a slave unit are installed at separate locations, as shown in FIG. 5a. When the base unit receives a call, the bell on the base unit or handset will ring, and when the handset is off-hook, the caller and the called party on the handset can talk through the base unit, and the handset can be connected to the handset. The system goes off-hook, performs dialing, and calls the called party via the base unit.

Therefore, when the above-mentioned call is received or when a call is made, the base unit receives the radio waves emitted from the handset during the off-book operation of the handset, and the telephone lines L1 and L2 are closed.
It has not been possible to control only the devices built into the base unit, such as an answering machine, from the handset, independent of the telephone line.

In the present invention, two methods are proposed to solve this problem. The first is 1", '2" in the on-hook state where the hook switch of the handset is open as shown in Figure 5a.
Power switch (not shown) when '3'' key is pressed
is on! 7 Emit radio waves modulated with DTMF tones to the base unit.

Here, when the °'1'' key is pressed, normally two frequencies, 697H2 and 1209H2, are output, but in the above-mentioned off-hook state, a switching circuit linked to the hook switch (not shown) outputs II. It connects to the A H7 oscillation circuit (not shown) and outputs two frequencies, 697H2 and 1633Hz.This is not yet used in Japanese touch-tone phones, but it is used for the two frequencies for the key °゛A''. It's the same as what you have.

Also, when the "2" key is pressed, two frequencies for the B" key are output, and when the II3.# key is pressed, two frequencies for the 'C" key are output (FIG. 5b).

When each output of these "'A-C" is decoded by a tone decoder (not shown) in the base unit, telephone lines L1 and L
To control an answering machine as described above without terminating the telephone number 2.

Of course, in the off-hook state with the hook switch closed,
If you press the '1~3'' key, the corresponding DTMF)-
(Figure 5b).

Also, if the owner uses a remote controller to operate the remote control while out and about, the KI A-C'' DTMF tones will not be output, so in this case, the 1 to 3'' DTM tones mentioned above will not be output.
It is programmed to operate the remote control using the F tone.

Additionally, this device has a voice recognition section as shown in FIG.
By switching the changeover switch SW1 to the right side, '1~
3" DTMF )-on by registering with ``ichi'', ``°ni'', ``su/'' or other name, PIN code, or speed dial in the same way as in the case of DTMF l--on. The response tape and reception tape can be controlled.

Next, the second method is to connect the handset of a cordless phone to two
When the parent and child press the button twice, the wireless communication between parent and child remains the same.Furthermore, in the above embodiment of the present application, a call from outside may come in even when a certain device is being operated without connection to the telephone line. obtain.

In this case, as shown in Figure 1, when the telephone is on-hook, H82 is connected to the ringer circuit, so it is ready to receive a ringing signal, and if you wish to answer the telephone, you must operate the answering machine. After hanging up the telephone, the handset (not shown) can be taken off-hook to answer the telephone. If you don't want to answer the phone, you can either leave it as it is, or switch the answering machine to automatic answer recording mode and answer the incoming call after locating the beginning of the answering tape or reception tape. You can also leave it to them. Furthermore, in the case of a cordless phone, it must be possible to receive incoming signals even when the handset is controlling equipment in the base unit.

Further, in this embodiment, a tape is used as described above, but in a solid-state recording and reproducing device, operations corresponding to rewinding and fast forwarding are instantaneously executed.

Therefore, when using a solid-state recording and playback device, the key operations are 2
If you press the key twice in a row, it will move back by 1 page and then stop. If you press the key 3 times in a row, it will skip 1 page and then stop. .

FIG. 5 shows a specific circuit using the above-mentioned solid-state recording and reproducing device, which is composed of a solid-state recording and reproducing device 60, a control LSI 610, and a dynamic random access memory DRAM 62.

The above control LSI is commercially available under the name T6.66B manufactured by Toshiba, for example. To explain the main terminals,
BEC4'' is a recording/playback switching terminal, and the 9H level is the recording mode and the L level is the playback mode. Also °'
5TART" is the start terminal for recording and playback operations,'
"S T OP" is a terminal for stopping the above-mentioned recording and playback operations, and "Phrase O" to "Phrase 4" are terminals for selecting phrases. Since they are composed of 4 bits, a maximum of 16 phrases can be used. "IN" is a terminal for selecting phrases. audio input terminal,
``OUT'' is an audio output terminal, and ``EO8'''' is an output terminal that outputs an H level when the bottom of each phrase is detected.

In order to record the above-mentioned response message on this solid-state recording and reproducing device, the same operation as in the case of the above-mentioned tape is performed. That is, I of the dial key 21 in FIG.
t Press the 271 key, then press the 3'' key.

Here the program will output ports "P23, P24, P2
5. Set P26'' to '1000'' and assign the first phrase for the response message. At the same time, select the H level recording mode for the output capo-1-P20. At the same time, the output port P16 is set to H level, and the analog switch G-15 is turned on to activate the microphone MIC.

Next, in the above state, when a start pulse is applied from the output port P21, the response message spoken into the microphone is input to the control LSI 61 via the input terminal IN, and the A/ The audio digitized by the D converter is stored in the DRAM 62.

When the response message is finished, press the "1" key once as in the case of the tape described above. When this suppression is detected by the program, a stop pulse is output from the output capo-1-P22 to cancel the above-mentioned recording operation.

The control LSI 61 uses the above-mentioned start pulse i.

When a stop pulse is applied, the start address and stop address of each phrase are stored in the memory built into the LSI, and when the stop address or the DRAM is detected to be full, the output terminal EQS is (End of 5peech) is H
become the level.

Therefore, when the It l F+ key is pressed once to confirm the response message recorded as described above, the output capo P2O is set to L level and switched to Te playback mode, as described above. When the first phrase is selected and a start pulse is applied, the response message is reproduced from the beginning and is amplified by the speaker SP via the output terminal OUT, the preamplifier 30, and the main amplifier 31.

Then, when the end of the response message is reached, the above LS
I sets the output terminal EO8 to H level and automatically stops the above-mentioned reproduction operation.

On the other hand, in order to transmit the response message in the automatic response recording mode, the output reproduced as described above is transmitted to the telephone line via analog switch G-13. To record the caller's message, select the next phrase using output ports P23 to P26, turn on analog switch G-14, and record in the same manner as for the response message described above. Can be done. That is,
Give the above stop pulse when the caller goes on-hook.

Also, to play the message during remote listening,
After specifying the next phrase of the response message, give a start pulse in the playback mode, and when the phrase reaches the end, the output terminal EO8 becomes H level (returns to L level with the start pulse), so this is sent to the CPU. It is programmed to automatically switch to the next phrase when detected via the message, and automatically play the entire message.

In the above-mentioned embodiment, an answering machine is described as an internal device of the telephone, but the present application is not limited to this.
