The selection circuit 68 is also connected to the reception channel display section 6 and is configured to display the selected channel. Furthermore, the aforementioned volume selection push-button switches Ss and Sa are connected to a volume selection circuit 69, and by switching the state of the volume control circuit 70 according to the state of the volume selection circuit 69, the volume selection circuit 69 changes the state of the speaker 5. 7) It is configured so that the sound i can be adjusted.

Conversely, each time the switch S6 is closed, the value is decreased by one level.

Note that the power-on command (TV ON command) signal A output from IFF4i of the voice recognition device 65 mentioned above is the same as the above-mentioned F
A power cut command (TV OFF) is sent to the set terminal S of F52.
Command) - The television function unit 51 is configured so that the signal B is input to the reset terminal R of the FF 52, the channel selection circuit C is input to the channel/channel selection circuit 68, and the volume level selection signal is input to the volume selection circuit 69. and voice recognition device 35
A connection relationship between the two is configured.

Further, the operation ON command signal output from the control block operation control signal receiving section 61 described above is transmitted to the volume control circuit 70 described above.
It is configured so that it is also input to the mute control terminal 70a. Also in FIG. 5, the power supply relationship from the power supply control section 56 to the television function section 51 is simply shown by broken lines.

Here, the operation of the remote control unit and the television when the time signal operation time or alarm operation time predetermined by the configuration of the time signal time detection circuit 14 or the memory contents of the alarm memory 12 is reached will be explained. .

However, the circuit shown in Figure 3 operates with positive logic, and when it is simply written as [H] or [L], it indicates that it is logically at the (H) level or [L] level. shall be.

Further, the bistable switch S mentioned above is maintained at the ON position, and therefore, power is supplied from the power supply control section 60 to the control block operation control signal reception section 61, and the reception section 61 is also in the operation ON state. shall be maintained.

By the way, in the remote control unit of this embodiment, the time signal time detection circuit 14 is activated every time the contents of the time counter 11 become one minute before the hour or one minute before half past the hour.
The time signal operation control signal J is outputted from the alarm operation control signal J, and the coincidence detection circuit 15 outputs an alarm operation control signal C6 every time the alarm set time stored in the alarm memory 12 coincides with the alarm set time.

On the other hand, the FF 72 and the AND circuit 73 constituting the unit operation control circuit 16 are in a state in which the transmission block 20 of the remote control unit automatically starts operating in response to the time signal operation control signal J and the alarm operation control signal C8. It was established to control whether or not the
The aforementioned push button type switch SI is connected to the T terminal of the aforementioned FF 72. Therefore, if the FF 72 is set in the set state by operating the switch S, the AND circuit 76 is maintained in the ON state, and as a result, the remote control unit responds to the time signal operation control signal J and the alarm operation control signal C8. , it becomes possible to automatically perform predetermined operations as described below. Also, in this way, the FF
When 72 is in the set state, the FF 7

3, the unit operation status display section 1c of the liquid crystal display device 1 displays 'AUTOMATI
The text "CSPE'ECHIN" is displayed to clearly indicate that the transmission block for remote control is ready to automatically start operating at a predetermined time.Therefore, prior to the following explanation, It is assumed that the above-mentioned FF 72 is also in the set state.

First, when the above-mentioned time signal operation control signal J or alarm operation control signal C6 is output, the signal J or C0 goes through the OR circuit 71, the above-mentioned AND circuit 76, and In order to be input to the differentiating circuit 75, one pulse signal formed here is F.
The signal is input to the set terminal S of the FF 76 to control the FF 76 to the set state. As a result, inverter 7
The output side of 7 is set to (L), and the AND circuits 78 and 79 are controlled to the ON state to transmit the audio signal.

The output side of the OR circuit 80 also becomes [L] unless an operation extension command signal -1p, which will be described later, is output from the input level detection device 28 of the sections 2 and 1.

By the way, when FF76 enters the sector state as mentioned above,
Nf Jarnell type FET (hereinafter abbreviated as N type FET) 18a that constitutes the transmission/reception block operation control element section 18
is in the ON state, and electrical energy is supplied from the power supply battery E to the above-mentioned receiving block 19 and control block operation control signal transmitting unit 29, so that the receiving block 19 becomes ready for reception. At the same time, the transmitter 29 starts transmitting the control block operation control signal.

On the other hand, in the control block provided on the side of the television main body, when the control block operation control signal receiving section 61 receives the control block operation control signal from the transmitting section 29, the receiving section 61 blocks the control block. An operation ON command signal is generated, and this operation ON command signal is input to the power supply control section 62. ,,,u,“□...1 from I
Worker, 664, speech recognition device 65, speech synthesis device 6
2, and power is turned on to the transmitting device 44. That is, since the above-mentioned time signal operation control signal J or alarm operation control signal C8 is formed on the remote control unit side and the FF 76 is set, the power supply is turned off as described above on the control panel side of the TV main unit. When the input is performed, the audio signal receiving unit 64, the audio recognition device 65, and the audio synthesizing device 6
2. The above preparations have been made for the transmitting device 44 and the like to operate.

On the other hand, timer circuits 81 and 82 forming the unit operation control circuit 16 are used to control the operation timing and operation duration of the speaker 3, the transmission block 20, and the reception block 19, which also serve as alarm elements. As mentioned above, when the output side of the inverter 77 and the output side of the OR circuit 79 become CL),
The timer circuits 81 and 8-2 are released from the reset state, and the AND circuits 78 and 79 are turned on.
The IHz input from the frequency dividing circuit 10 via
(Start counting 0 signals.

Here, when the timer circuits 81 and 82 respectively count a predetermined number of signals (that is, when a predetermined time 11 and 12 respectively elapse), the output sides Tl and T2 become (
H), and in this example, each of the timer circuits 81 and 82 has 1.H). (1,
It is configured so that

- That is, - as an example, it is sufficient to configure so that t = 5 seconds and t = 120 seconds (2 minutes). Therefore, as described above, timer circuits 81 and 82
After starting the counting operation of the signal z, first, when time t1 elapses, the timer circuit 81
One output side T1 of the timer circuit 81. becomes (H), and then, when time t2 has elapsed, the output side T of the timer circuit 82 becomes [H], and so on, one output side T1 of the timer circuit 81. The output side of 82 becomes (H).

By the way, after -j when the FF 76 is set, that is, after each timer circuit 81 and 82 starts counting, 1. Until the time elapses, the output sides Tt and Tt are both in the (L) state, and therefore the output side of the EX-OR circuit 86 is in the [L] state.

On the other hand, since the FF76 is in the set state,
The output side of the INH circuit 84 is at (H), and as a result, until the above 21 hours have elapsed, the speaker 6 is first driven by the buzzer sound generation signal forming circuit 17, and when the alarm buzzer sound is generated, the speaker 6 is driven. , the user is notified that the alarm set time has arrived, or that the hour or 30 minutes past the hour is approaching.

Next, when 21 hours elapse and the output side T becomes (H), the output side of the EX-OR circuit 86 becomes [H] until another 27 hours elapse and the output side T2 also becomes (H3). Become. .

As a result, even though the F F 76 label is still in the set state, the output side of the INH circuit 84 becomes [L], and the generation of the alarm buzzer sound is interrupted. ' becomes CI(), the N-type FET 18b of the transmission/reception block operation control element section 18 is turned on, power is turned on from the power supply battery E to the audio signal transmission section 21, and the transmission is performed. The unit 21 is also turned on. That is, in this state, the voice input through the microphone 2 is converted into a radio wave signal by the transmitter 21 and transmitted. Further, the transmitted signal is received by the audio signal receiving section 64 which is already in the operation ON state as described above, and is again converted into an audio analog signal by the receiving section 64, and then sent to the aforementioned speech recognition device 65. will be entered into.

That is, in this state, when a voice television operation control command is input through the microphone 2, a series of processes for controlling the operation of the television function section 51 are executed as described below. . Note that since the output side of the EX-OR circuit 86 is connected to the decoder/driver circuit 14, the EX-OR circuit 86 is
- When the output side of the OR circuit 86 becomes [H], a message 1SPEECHIN' is displayed on the unit operation status display section 1C of the liquid crystal display device 1 to clearly indicate that audio input from the microphone 2 is possible. It is controlled to blink easily.

Similarly, on the control block side of the TV main unit,
The control block operation display panel 8 is configured to display the characters '5PEECHIN' by receiving the operation ON command signal from the control block operation control signal receiving section 61 described above. Therefore, it is clearly indicated that voice input is possible on either side of the remote control unit or the television body.

Here, in this embodiment, the types of television operation control that can be processed through voice input commands are as follows: Operation of the television function section 51 + 77 ON-OF
This includes control of F (power on/off), designation of the pollium level, designation of the reception channel (reception frequency), etc.

First, a voice command such as "switch on" is inputted from the microphone 2, and then sent to the voice recognition device 65 as a voice analog signal via the voice signal transmitter 21 and the voice signal receiver 34 described above. When the command word is recognized by comparison with the characteristic information of the voice "switch on" which is input and stored as a standard pattern in the 5PU 40, the IFP 4
A question response signal G corresponding to the word "switch on/" recognized by the voice processor 1 is output, and this signal is input to the speech synthesizer 66. As a result, the voice synthesizer 3B generates a voice signal for pronouncing the question "Switch on?", for example, and this voice signal is input to the transmitter 44, where it is converted into a radio wave signal and transmitted. will be done.

When this transmitted radio wave signal is received by the receiving block 19 of the remote control unit mentioned above,
It is again converted into an audio signal and input to the speaker 6, and the question "Switch on?" is sent to the speaker 6 to confirm the command.
The word will actually be pronounced. At this time,
Predetermined confirmation words, such as "Oh, kay."
When words such as ``etc.'' are input into the microphone 2 by voice, the voice signal of the confirmation word is transmitted to the voice recognition device 65 via the voice signal transmitting section 21 and the voice signal receiving section 64.
will be entered into. Here, when it is recognized which question has been answered by comparing it with the standard voice pattern of "Okay" stored in the 5PU 40, the IFP 41 issues an actual power-on command (TV ON). One pulse signal is output as the command signal A and is input to the set terminal S of the FF 52 mentioned above. As a result, the FF 52 is forced to enter the cent state, so the power supply control section 56 turns on the power to the television function section 51, and the television function section 51 is controlled to be in the ON state. , Conversely, if the voice command "switch off" is recognized and confirmed in the same way, it is activated by one pulse signal output from the IFP41 as the power cut command (TV OFF command) signal B. , FF power supply control section 53
The supply of power to the television function section 51 is cut off, and the television function section 51 enters the operating/OFF state.

Next, predetermined words such as "Channel 1", "Channel 2", "Channel Sun", etc. to designate the receiving channel are input as audio into the microphone 2, and the When the command is recognized by the voice recognition device 65, and furthermore, the words of approval such as "all-key j" in response to a confirmation question are also recognized, a channel selection signal C is output from the IFP 41 according to the above specified contents. That is, the channel selection signal C is input to the Q channel selection circuit 68, and as a result, the tuner section 54 is controlled so that the radio wave corresponding to the designated channel is received. It turns out.

Similarly, for example, "volume one", "volume one", "volume one", "volume one", "volume
When words predetermined to specify the volume level, such as "2", "Volume Sun", etc., are input as voice into the microphone 2, and the command is recognized and confirmed by the voice recognition device 65. In this case, a volume/bell selection signal is output from IFPλ1 according to the above specified contents. The volume level selection signal is input to the volume selection circuit 6.8 described above, so that
It functions to adjust the audio output level from the speaker 5 to the specified content by switching the volume adjustment resistor of the volume control circuit 70.

Note that if the words in the above question are incorrect, the user can simply input the voice command again.

On the other hand, while the audio signal transmitter 21 of the above-mentioned Youni remote control unit 21 is operating, audio is input to the microphone 2 and the input level detector provided in a part of the audio signal transmitter 21 28, when it is determined that the level of the input voice differs by a certain level or more, the input level detector 28 outputs an operation extension command signal P and outputs an operation extension command signal P to the OR circuit. 80, the timer circuit 82 is reset.

Further, as described above, when the aforementioned 22 hours have elapsed without any new input of the operation extension command signal P, the output side T2 of the timer circuit 25 also becomes (H). As a result, both T1 and T2 become (H), so E
Since the output side of the X-OR circuit 86 becomes (L) and the N-base transistor 18b is turned off, the power supply from the battery E to the audio signal transmitter 21 is also cut off, and the audio The signal transmitter 21 will automatically return to the OFF state.

Furthermore, when the output side T2 of the timer circuit 82 becomes (H), the output side of the OR circuit 85 becomes [L], so the FF 76 also returns to the reset state, and as a result, the output side of the inverter 27 becomes (H). ) and the timer circuit 81
．． Since 82 is also held in the reset state,
The unit operation control circuit 16 returns to the normal state before the time signal operation control signal J or the alarm operation control signal C8 was generated.

Furthermore, when the FF7'6 returns to the reset state, the N-type transistor 18a is also controlled to the OFF state, so power supply to the control block operation control signal transmitter 29 and the receiving block 19 is also cut off, and the control The transmission operation of the block operation control signal and the reception operation by the reception block 19 are also stopped.

On the other hand, on the television main body side, when the control block operation control signal receiving section 61 detects that the transmission of the control block operation control signal has been stopped as described above, the receiving section 6
Since the output of the operation ON command signal from 1 is also stopped,
In the end, the power supply controller 62 is connected to the audio signal receiver 64, the audio recognition device 65, the audio synthesizer 66, and the transmitter 4.
The power supply to the control program 4 is also cut off, these operations are automatically stopped, and the control program operation display panel 8
The display will also be erased.

As described above, in this embodiment, since the input level detector 28 automatically extends the operation time for transmitting/receiving audio input signals of a certain level or higher and for voice recognition, the television function unit 51 This prevents a situation in which voice input suddenly becomes impossible during a line in which instructions regarding the operation of the computer are being input by voice.

In addition, if no new audio input of a certain level or higher is detected over a period of 27 hours, the transmission/reception of audio signals and voice recognition operations are automatically terminated, so the transmission block This also prevents the 2°, the audio signal receiving unit 64, the audio recognition device 35, etc. from continuing to operate indefinitely, causing malfunctions and wasting power.

In this embodiment, as described above, while the operation ON command is being output from the control block operation control signal receiving section 61, that is, the voice signal receiving section 64 and the voice recognition device 65
etc. are in the ON state, in order to prevent the speech recognition device 65 from malfunctioning due to the audio output from the speaker 5 of the television function section 51, the audio output from the speaker 5 is controlled to be muted. There is.

However, it is also inconvenient that the above-mentioned mute state is always maintained for a predetermined period of time even though there is no intention to specify the operation of the television.

Therefore, in this embodiment, when the push button switch s, 5) of the remote control unit is pressed, the output side of the OR circuit 85 becomes (H) and the FF 76 is returned to the reset state, as described above. timer circuit 82
It is also possible to forcibly control the output side T2 to be in exactly the same state as when it becomes (H). That is, in this embodiment, when the operation of the remote control function is started even though there is no need to specify the operation of the television, or when the specification is finished, the above-mentioned me: The structure is such that it is possible to quickly escape from the L-t state.

On the other hand, in the unit operation control circuit 16 described above, FF7
2 is in the reset state, the AND circuit 76 is also OFF.
In order to maintain the F state, even if the time signal operation 5 control signal J and the alarm operation control signal C8 are formed, these are blocked by the AND circuit 76, and the above-mentioned transmission/reception and voice recognition operations are interrupted. is not started automatically.

Therefore, if remote control operation is not necessary, the FF 72 may be reset by operating the switch S1. Further, at this time, the display on the unit operation state display section 1c is in the erased state.

Note that when the switch S2 is pressed, a single pulse signal is formed in the differentiating circuit 75 regardless of the state of the FF 72 described above, so a series of operations exactly the same as in the above case are immediately started. It turns out. Also at this time, the unit operating state display section 1c displays "5PEE".
The display "CHIN" will be controlled to a blinking state.

As described above, according to the present invention, as the alarm set time approaches or reaches a predetermined time such as on the hour or half past the hour, the audio signal transmission and reception operations in the remote control are automatically performed. When the desired or appropriate time is reached, the remote control unit can be started without any manual operation.
By inputting various operation commands by voice and having them recognized by voice, or by asking the recognition results again by voice and confirming them, you can reliably control the operation of specified electronic devices such as televisions and radios in a kind of dialogue format. It becomes possible to control the operation, and the operation mode of the electronic device can be made very innovative and easy.

Further, by configuring the operation control signal formed based on the contents of the time counter to control the operations of at least the transmitting means and the receiving means of the remote control unit, the transmitting means and the receiving means are continuously driven. This makes it possible to prevent wastage of power from the power supply battery and malfunctions caused by unintentional voice input. ,・7P Furthermore, as in the case of the above-mentioned embodiment, when the alarm approaches or reaches a predetermined time such as the cent time, the hour, or half past the hour, first an acoustic alarm element such as a remotely controlled buzzer or speaker is activated. If the configuration is configured to clearly indicate that voice input is possible by activating the device or by activating an electro-optical alarm display means, the user's attention can be clearly drawn. This allows smooth voice input from the user.

In particular, television and radio programs are generally organized so that they change from one program to another on the hour or 30 minutes past the hour. In addition to notifying the user of proximity and arrival, the user's mood and needs at that time, whether there is a program they want to watch or listen to, etc.
If electronic devices such as radios and televisions can be configured to operate freely, flexibly, quickly, and in the desired manner according to the situation, it is possible to command them by voice input.
A product that is well suited to the above-mentioned temporal characteristics of radio and television program programming and that can provide a novel and new sense of use will be realized. ' Also, in the above embodiment, the remote cone door 0-
In addition to transmitting and receiving means for audio signals, control block operation control signals are transmitted and received between the unit and the TV itself.
By also providing the receiving section 29.61, the operation of the control panel consisting of the audio signal receiving section 64, the speech recognition device 65, etc. on the television main body side can be controlled from the remote control unit side. However, according to such a configuration, the control block can be automatically operated only when necessary, so that power consumption on the control block side can also be prevented.

In this case, the control block only needs to constantly supply power to the control block operation control signal receiving section 61.

Further, the connection between the control block operation control signal transmitting/receiving sections 29 and 61 may be made by, for example, an ultrasonic signal instead of a radio wave signal. On the other hand, the audio signal transmitting/receiving section 21.
64, it is actually preferable to use FMtlI: as the radio signal.

Furthermore, in the above-described embodiment, the speaker 6 is configured to generate an alarm buzzer sound when the time signal time, etc. arrives, but by using the voice synthesizer 66, the arrival of a predetermined time can be made by voice. It is also possible to configure the system to notify. In that case, when the time signal time etc. arrives, the contents of the time counter 11 at that time are converted into an appropriate coded radio signal, transmitted to the receiving means of the control block on the TV main body side, and voice synthesis is performed. A device 66 synthesizes an audio signal according to the coded wireless signal, converts the audio signal back into a wireless signal, and sends the signal to the receiving block 1 in the remote control unit.
As a result, for example, [It will be 10 o'clock soon.] ] may be output from the speaker 6.

Furthermore, in the above-mentioned embodiment, the time signal operation is performed one minute earlier than the hour or half past the hour, but this is because the program starts on the hour or half past the hour. This design allows for the desired control to be completed and executed before the process begins.

In this case, it is preferable to configure the system so that the notification operation is performed approximately 10 seconds to 3 minutes before the hour or 30 minutes before the hour. It's okay.

On the other hand, in the above-mentioned embodiment, after the time signal operation control signal J or the alarm operation control signal C0 is generated, the remote control unit C proceeds with the operation based on the output signal from the unit operation control circuit 16 consisting of a timer circuit, etc. However, the progress of each process such as the voice recognition device and alarm element is controlled by the ROM.
It is also possible to configure the process to be performed by

In that case, store the progress program etc. in the ROM in advance, knot the addresses in the ROM sequentially according to the contents of the counter synchronized with the clock signal, and configure the corresponding ROM each time. Possible options include doing so.

Furthermore, in the embodiment described above, the transmission block 20 and Receive block 1
For example, the audio signal transmitter 21 transmits the operation control signal J or c via the output of a timer circuit or the like.
It is configured so that the operation is indirectly controlled by the controller o.

However, in addition to this embodiment, the transmission block 2 is directly controlled by the operation control signal J or C0.
0 or all reception blocks 19 can be configured to start driving.

In the above embodiment, the operation control signal is configured to control both the operation of the speaker 6, which also functions as an alarm element, and the operation of the transmission block 20 and the reception block 19. It is also possible to form the control signal for the operation and the operation control signal of the transmission block separately (ie separately at a suitable time interval from each other).
