BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for remotely operating home electric appliances such as personal computers, televisions, videos, air conditioners and the like of different manufacturers.

[0002]

2. Description of the Related Art In a normal remote control device,
Since a remote control code corresponding to a home electric appliance such as a television / video is provided in advance, remote control devices corresponding to the number of home electric appliances such as a television / video are required.

FIG. 4 is a schematic diagram showing an example of this conventional example. Remote control device for personal computer (4.
1), a remote control device for a television (4.
2), remote control device for video (4.3)
And each remote control device was required. Therefore, conventionally, it was necessary to use the same number of remote control devices as the number of home appliances. In addition, in the case of multifunctional home appliances, switch buttons are required for the number of functions to be controlled, and the required number of switch buttons also increases, resulting in an increase in the size of the remote control device. was there. With this increase in size, it has become impossible to operate easily and easily with one hand.

[0004]

In the above-mentioned prior art, it is necessary to use a plurality of remote control devices to remotely control a plurality of home appliances. Therefore, there is a problem that it is confusing which remote control device can remotely control which home electric appliance, and the operation is not easy because the operability is different for each remote control device.

[0005] In addition, in order to sufficiently extract each function of a multifunctional home appliance, switch buttons are required as many as the functions to be controlled. Therefore, it is necessary to provide a large number of switch buttons required for the remote control device. Therefore, as a result of the increase in the number of switch buttons,
There is a problem that the remote control device becomes large.

An object of the present invention is to provide a remote control device that can control home appliances of different manufacturers with one remote control device in order to solve the above-mentioned problems.

Another object of the present invention is to provide a remote control device capable of remotely controlling a plurality of home electric appliances with a single remote control device while minimizing installation of switch buttons for a multifunctional home electric appliance. It is in.

Another object of the present invention is to provide a miniaturized remote control device for improving operability.

[0009]

In order to achieve the above object, a small and multifunctional remote control device according to the present invention comprises a maker corresponding mode for giving a maker corresponding code,
A mode switch button that switches between intelligent mode that assigns an intelligent code that changes the type of remote control signal, and a function that is selectively used for each mode selected with the mode switch button. In the case of, a plurality of function switch buttons for selecting an intelligent code, a function control switch button for instructing a specific function for remote operation, actually issuing a remote control signal when pressed, and controlling various functions, A maker code table corresponding to the function switch button used in the manufacturer compatible mode, and an intelligent code table corresponding to the function switch button used in the intelligent mode. A table, and means for storing in advance a function control code table specifying the functions, and means for holding senses the mode switch button, and means to acquire and depressed state of the function switch button held,
Means for acquiring and holding a state in which the function control switch button is pressed, means for synthesizing a remote control signal according to the pressed state when the function control switch button is pressed, and emitting the synthesized remote control signal as infrared light Means for remotely controlling home electric appliances of different manufacturers.

When the function control switch button is pressed, it is preferable to determine whether the mode flag of the mode switch button is ON or OFF.

Further, when the mode flag is OFF, it is determined which one of the plurality of function switch buttons has been pressed, and the intelligent code of the corresponding function, the function control code, and the maker code not indicating a specific maker are used as the remote control signal. It is preferable to synthesize and transmit the remote control signal by infrared rays.

Further, when the function switch button is not pressed, it is preferable that only the conventionally compatible function control code is used as the remote control signal and the remote control signal is transmitted by infrared rays.

When the mode flag is ON, it is determined which one of the plurality of function switch buttons has been pressed, and a maker corresponding code and a function control code of the corresponding function are synthesized into a remote control signal, and the remote control signal is generated. Preferably, transmission is by infrared.

Further, when the function switch button is not pressed, it is preferable that the default maker code and the function control code are combined with the remote control signal, and the remote control signal is transmitted by infrared rays.

Further, it is preferable that after the remote control signal is transmitted, the mode flag of the mode switch button and the function flag of the function switch button are cleared.

The small and multifunctional remote control device of the present invention has a mode switch button for distinguishing between a maker corresponding mode and an intelligent mode, and a maker is selected in the maker corresponding mode. Intelligent code (F1, F
2, F3, etc.), a maker code table corresponding to the function switch button used in the maker mode,
A means for storing in advance an intelligent code table corresponding to a function switch button used in the intelligent mode and a function control code table for designating a function, sensing and holding the mode switch button, and pressing the function button Means for acquiring and holding a state, means for acquiring and holding a state in which a function control switch button is pressed, means for combining a remote control signal according to a button pressed state when the function control switch button is pressed, and combining Means for emitting the remote control signal as infrared light, and the combined remote control signal is composed of a total of 6 bytes, each consisting of 2 bytes in the order of intelligent code, manufacturer code and function control code. The condition of this means is that the home electric appliance can receive all remote control signals of 4 bytes for the manufacturer mode, 2 bytes for the conventional mode, and 8 bytes for the intelligent mode. The remote control signal is an infrared signal, and hardware conditions such as frequency and the number of bits of one character are unified.

In the remote control device of the present invention,
Set the mode switch button state that the operator wants to use. When the mode is set to the maker corresponding mode, the function switch button corresponding to the maker to be remotely operated is pressed, and thereafter, “0” to “9”,
If you press one of the buttons “#” or “*”,
The remote control signal is synthesized. For example, since the mode corresponds to the manufacturer, the code “1234” (provisional) corresponding to the function switch and the function control code “11”
EE "(provisional), and" 123411EE "is transmitted by infrared rays as a remote control signal.In the case of the intelligent mode, if the conventional remote operation is desired," 0 "to" 9 ","#", When one of the switch buttons “*” is pressed, the remote control signal is synthesized, for example, when the “0” switch button is pressed, “00” representing 0 and “FF” of the inverted code are displayed as the function control code. "00FF" (temporary).
This is transmitted as a remote control signal. In the case of intelligent support, after pressing the function switch button and pressing one of the switch buttons “0” to “9”, “#” or “*”, the function switch button “F1F1” and the manufacturer Since the code is not set, “0000” and the function control code “00FF” (temporary) are synthesized, and “F1000”
000FF "is transmitted as a remote control signal.
