It has a mode of operation as a remote control device for transmitting data (hereinafter referred to as an auxiliary mode).

First, the operation of the normal mode will be described. The user's control command input through various function keys of the key selection unit 32 is converted into a corresponding electrical signal and input to the control unit 40. The controller 40 executes a built-in program and reads encoded data corresponding to an electrical signal input thereto from the memory 34 and provides the infrared data to the infrared transmitter 36. The infrared transmitter 36 converts the encoded data input thereto into an infrared signal and transmits the infrared signal. The control unit of the controlled device (not shown) receives the infrared signal transmitted from the remote control device through its infrared receiver and decodes it to control the controlled device to perform the intended operation by the user.

Next, the operation in the auxiliary mode will be described. Normal mode and auxiliary mode have mutually exclusive relationship, which is designated by AUX key. The auxiliary mode has two independent modes. One of them is a mode (referred to as a learning mode) for receiving an infrared signal transmitted from another remote control device and assigning the encoded data detected therefrom to various function keys of the key selection unit. A mode of transmitting coded data learned through the following (hereinafter referred to as a user mode). Learning mode and user mode are specified by the LEARN key.

First, the operation of the learning mode will be described.

The key selector 32 generates an electrical signal corresponding to the function key selected by the user and transmits the electrical signal to the controller 40. The control unit 40 decodes the electrical signal from the key selection 32 to obtain a code indicating the selected function key and stores it.

② The user operates another remote control device to transmit the infrared signal corresponding to the selected function key.

The infrared receiver 38 receives the infrared signal transmitted from another remote control device (not shown), extracts the encoded data, and provides it to the controller 40.

Learning to associate coded data having a code system suitable for the controlled device by the operation to the function key of the remote control device of the present invention is performed. By repeating the above operation, the necessary function keys are learned.

Next, the user mode will be described. In the user mode, the operation of the key selection unit 32 is the same as that in the normal mode except that the encoded data associated with the learning mode is sent. The user's control command input through various function keys of the key selection unit 32 is converted into a corresponding electrical signal and input to the control unit 40. The controller 40 executes a built-in program and reads encoded data corresponding to an electrical signal input thereto from the memory 34 and provides the infrared data to the infrared transmitter 36. In this case, the encoded data to be read is data learned through the learning mode. The infrared transmitter 36 converts the encoded data input thereto into an infrared signal and transmits the infrared signal. The control unit of the controlled device (not shown) receives the infrared signal transmitted from the remote control device through its infrared receiver and decodes it to control the controlled device to perform the intended operation by the user.
