SOLUTION: A user depresses an operation key of a remote control transmitter 1 twice. A reception section 3 of a device 2 receives a remote control signal of the 1st depression, an identification section 4 identifies a control code, a CPU 11 reads voice data denoting a function corresponding to the control code from a voice data storage section 5, a voice processing section 6 conducts voice synthesis from the voice data, and a speaker 7 sounds the voice. A memory section 8 stores the identified control code. A control code resulting from a received remote control signal of the 2nd depression from the remote control transmitter and from being identified by the identification section is given to a discrimination section 9 and compared with data read from a memory section. When they are coincident, a signal is fed to a circuit to be controlled 10 via the CPU, which conducts corresponding control.

FIG. 1 is a block diagram of a main part of an embodiment of a remote controller according to the present invention. In the figure, 1 is a remote control transmitter, 2 is a main part of a device controlled by the remote control transmitter 1, 3 is a receiving unit for receiving a signal transmitted by a key operation of the remote control transmitter 1, and 4 is a receiving unit 3. An identification unit for identifying a control code of a remote control signal received at
Reference numeral 5 denotes a voice data storage unit (comprising a ROM or a RAM) for storing voice data representing a function corresponding to the control code. Reference numeral 6 denotes voice data representing a function corresponding to the control code identified by the identification unit 4. A voice processing unit for reading and synthesizing voice from the data storage unit 5; a speaker 7 for outputting voice based on a signal from the voice processing unit 6; a memory unit 8 for storing a control code identified by the identification unit 4; By the next key operation within a predetermined time by the remote control transmitter 1,
The discriminating unit 10 that compares the control code received by the receiving unit 3 and identified by the identifying unit 4 with data read from the memory unit 8 to determine a match is identified by the identifying unit 4 based on a signal from the identifying unit 9. A controlled circuit (for example, a power ON / OFF circuit, a TV receiver tuning circuit, a volume control circuit, etc.) controlled based on the control code thus set, and a CPU (Central Processing Unit) 11 for controlling the above-described units. .

Next, the operation of the remote controller according to the present invention will be described. To operate the device 2 by remote control, the same key of the remote control transmitter 1 is pressed twice, for example, the channel "1" of the TV receiver. From the remote control transmitter 1, a control code for controlling the device 2 corresponding to the pressed key is
It is transmitted by an infrared signal or the like together with a custom code indicating the manufacturer and model of the device 2. The signal of the first key operation of the remote control transmitter 1 is received by the receiving unit 3 of the device 2,
Input to the identification unit 4 via 11 to identify the custom code representing the own device, and identify the control code "channel 1".
The CPU 11 reads “1 channel” audio data representing a function corresponding to the control code identified by the identification unit 4 from the audio data storage unit 5, transfers the audio data to the audio processing unit 6, synthesizes the audio, and “ One channel "is output as sound. At the same time, the control code “channel 1” identified by the identification unit 4 is stored in the memory unit 8 via the CPU 11. The second signal from the remote control transmitter 1 is received by the receiving unit 3, and the control code “channel 1” is identified by the identifying unit 4. This data is input to the determination unit 9 via the CPU 11 and
Compare with the data read from the memory unit 8 via the PU11,
At the coincidence, the control signal of "channel 1" is sent to the corresponding controlled circuit, that is, the channel selection circuit via the CPU 11, and the reception channel is switched to "1".

If the control code of the second signal from the remote control transmitter 1 is not "Channel 1" but, for example, "Channel 3", it means that the first key pressed was incorrect. The control code “channel 3” identified by the identification unit 4 is compared with the control code “channel 1” read from the memory unit 8 by the determination unit 9 and a mismatch is determined. Based on the signal from the determination unit 9, the voice data of the identified control code “3 channel” is read out from the voice data storage unit 5 via the CPU 11, and voice is synthesized by the voice processing unit 6, and “3 channel” is output from the speaker 7. Output audio.
Then, the control code “channel 3” is input to the memory unit 8 and the stored control code of “channel 1” is rewritten to “channel 3”. Then, when the control code of “channel 3” is transmitted next from the remote control transmitter 1, this signal is received by the receiving unit 3, and the control code “channel 3” is identified by the identification unit 4 and determined through the CPU 11. The data is input to the unit 9 and compared with the data read from the memory unit 8 via the CPU 11. When the data matches, a control signal of "Channel 3" is sent to the channel selection circuit via the CPU 11, and the reception channel is switched to "3". When the same key of the remote control transmitter 1 is continuously pressed three or more times, the same control code is identified for the second and subsequent times, so that the device 2 repeats the same control as the second key operation.

The control code stored in the memory unit 8 is deleted after a predetermined time, for example, one second has elapsed. This is to prohibit the control code received and identified by the next operation of the remote control transmitter 1 from operating as a continuation of the previous remote control operation, and to be able to cope with new remote control. When the same control code is identified three or more times in succession by the identification unit 4, a signal is continuously sent to the controlled circuit 10 to continuously control the designated function. This is because when the same control code is continuously transmitted by one key operation, such as when the operation key of the remote control transmitter 1 increases or decreases the volume, the first control code is identified as “increase the volume”.
Is output as a voice, and while the key is pressed, the control for increasing the volume is continuously performed.

The audio signal from the audio processing unit 6 may be input to an audio circuit (not shown) of the device 2 and output from a speaker for audio output of the device 2 (separate from the speaker 7). Good. Further, when the receiving unit 3, the identification unit 4, the audio data storage unit 5, the audio processing unit 6, the memory unit 8, the determination unit 9 and the CPU 11 are always operated by the preheat power source and the keys of the remote control transmitter 1 are operated. Also, the control function is output by voice even when the operation of the device 2 is stopped. Further, a switch for switching the audio output of the control function to stop is provided, and when the switch is operated to the stop side, the operations of the audio data storage unit 5, the audio processing unit 6, the memory unit 8, and the determination unit 9 are stopped, and the control function is stopped. Is stopped, and C is received based on the control code received by the receiving unit 3 and identified by the identifying unit 4.
A signal is sent to the corresponding controlled circuit 10 via the PU 11 to control the designated function, that is, the control of the controlled circuit 10 is performed by one key operation of the remote control transmitter 1. Good.

[0017]

As described above, according to the remote control device of the present invention, if the key of the remote control transmitter is pressed once, if the key of channel 1 is used, the sound of "1 channel" is output from the device. If you press the key of channel 3 incorrectly, press the key of channel 3 to output the sound of "3 channel", and then press the same key to select the channel of 3 channel. If you make a mistake, you can directly control the device to the desired operation by pressing the correct key again. Can be avoided.
