2. Description of the Related Art Conventionally, in a remote control device,
BACKGROUND ART A controlled device, for example, an electronic device such as a video tape recorder, a television device, or a stereo device is operated by a remote control transmitter (hereinafter, referred to as "remote control transmitter") using infrared light. The infrared light output from the remote control transmitter is coded based on the remote control signal, and the remote control signal is generally different for each electronic device. Therefore, there is known a so-called learning remote control transmitter that can learn a remote control signal output from a remote control transmitter for another electronic device so that, for example, another electronic device can be operated by one remote control transmitter. Here, FIG. 7 shows a configuration of a conventional learning remote control transmitter.

In FIG. 7, when the operation section 11 of the learning remote control transmitter 10 is operated, the operation key operated by the microcomputer (hereinafter referred to as "microcomputer") 12 is discriminated and the memory control signal SA corresponding to the operation key is detected.
Is generated. The microcomputer 12 is connected to a memory unit 13 that stores remote control signals in advance and a memory unit 14 that can newly store remote control signals.
The remote control signal CA stored in the memory 14 or the remote control signal CB newly stored in the memory unit 14 is selected and read based on the memory control signal SA and supplied to the modulation unit 15.

The modulator 15 generates a carrier signal of a predetermined frequency and the carrier signal is a remote control signal C.
It is modulated by A and supplied to the light emitting unit 17 via the transmission amplifier unit 16 as a modulation signal MA.

The light emitting section 17 is constructed by using an infrared light emitting diode. By driving the infrared light emitting diode based on the modulation signal MA, the learning remote control transmitter 10 codes a code according to a remote control operation. The converted infrared light is output.

On the other hand, in the remote control light receiving section of the electronic device which is the controlled device, the infrared light coded from the learning remote control transmitter 10 is received to generate a reception signal, and this reception signal is demodulated. Is used as a remote control signal.
The remote control signal is discriminated by the microcomputer and the operation control signal is output corresponding to the remote control signal to control the operation of the electronic device according to the remote control operation.

When learning a remote control signal of a remote control transmitter of another electronic device, the coded infrared light output from the other remote control transmitter is transmitted by the remote control transmitter 20.
Is supplied to the remote control light receiving unit 21 of.

The remote control light receiving section 21 is composed of a phototransistor or the like, and the infrared light output from the remote control transmitter of another electronic device is photoelectrically converted to receive signal R.
B is generated. This received signal RB is received signal processing unit 2
2 is supplied.

In the reception signal processing unit 22, the reception signal RB is amplified and the band is limited, and the signal NB of the component of the carrier frequency is supplied to the demodulation unit 23.

The demodulation section 23 demodulates the signal NB to generate a remote control signal CB. This remote control signal CB
Are stored in the memory unit 14 in correspondence with the operation keys for the learning of the operation unit 11. That is, when the remote control signal CB is stored in the memory unit 14 based on the memory control signal SA generated by the microcomputer 12 when the operation key for learning is operated and the operation key for learning is operated, The remote control signal CB is read from the memory section 14 based on the memory control signal SA from the microcomputer 12, and infrared light coded based on the remote control signal CB is output.

In this way, since the remote control transmitter 10 can also store remote control signals of other electronic devices, one remote control transmitter can also control electronic devices of different manufacturers.

[0012]

By the way, when the remote control transmitter having the learning function is used, the remote control transmitter needs a microcomputer for controlling an operation for storing a remote control signal of another electronic device. At the same time, the electronic device requires a microcomputer for controlling the operation of the electronic device by discriminating the remote control signal, which increases the cost.

Further, for example, when operating a stereo device and a television device capable of reproducing a compact disc on which an image signal is recorded, with one remote control transmitter, it is necessary to sequentially operate the operation keys of the remote control transmitter and the stereo system. If the remote control light receiving parts of the device and the television device are close to each other and do not face the same direction, the remote control transmitter must be oriented in the direction of the stereo device or the television device each time. It was complicated.

Therefore, the present invention provides a remote control device which is inexpensive and can easily operate a plurality of electronic devices.
