2. Description of the Related Art Household audio equipment, video equipment,
Furthermore, in air conditioners and the like, remote control is widely used. In remote control of such a device, the device body, that is, the controlled device is usually regarded as being accompanied by a remote control device for transmitting a remote control signal, which is generally called a commander. A remote control signal is transmitted from the remote control device at a position distant from the control device, the remote control signal is received by the control signal receiving unit included in the controlled device, and various controls in the controlled device are received. It is performed based on the control signal.

In such a case, the remote control signal sent from the remote control device and received by the control signal receiving unit provided in the controlled device is surely received by the specified controlled device. Therefore, for example, in FIG.
As shown in FIG. 1, start code data STC representing the beginning, type of controlled device (audio disc player, audio tape recorder, television receiver, video disc player, video tape recorder (VTR), VTR integrated video camera, etc. ), The category code data CGC, the key code data KYC representing the operated one of the plurality of key switches provided in the remote control device, that is, the type of control to be executed, and the control to be performed. It is formed on the basis of a data group that includes the identification code data IDC specifying the controlled device in time series. The number of bits forming each code data is, for example, 5 bits for the category code data CGC, 7 bits for the key code data KYC, and 16 bits for the identification code data IDC assigned to each device. .

The remote control device is provided with a transmission side identification code memory section for storing identification code data, and is read from the transmission side identification code memory section as start code data, category code data and key code data. A remote control signal corresponding to a data group formed by adding the identification code data is formed, and infrared rays from the light source are modulated by the remote control signal and sent out,
The remote control signal is transmitted. Further, the controlled device is provided with a receiving side identification code memory section in which assigned identification code data is stored in advance, and based on a detection output signal obtained by detecting infrared rays from the remote control device. As a result, a remote control signal is obtained, and further decoding is performed on the remote control signal to obtain a data group corresponding to the remote control signal. Then, the identification code data in the data group corresponding to the remote control signal and the identification code data read from the receiving side identification code memory unit are collated, and when they match, the category code in the remote control signal Control is performed according to the data and the key code data.

[0005]

As described above, when the remote control device controls a specific controlled device, the identification code data stored in the transmission side identification code memory section of the remote control device is used. It is necessary that the identification code data stored in the reception-side identification code memory unit of the specific controlled device match each other. Therefore, for example, as disclosed in JP-A-63-26098, a switch for setting an identification code is provided on the controlled device side, and the switch for setting the identification code is operated to set the identification code. When the controlled device receives the remote control signal from the remote control device including the identification code data previously stored in the transmitting side identification code memory section under the condition, the receiving side identification code in the controlled device is received. It has been proposed that the memory section stores the same identification code data as the identification code data previously stored in the transmission side identification code memory section of the remote control device.

However, since the setting of the identification code on the controlled device side as described above requires the user of the controlled device to intentionally perform the setting, the user is annoyed. There is a problem of causing it.

In view of the above point, the present invention sends and sends a remote control signal corresponding to the data group including the identification code data for identifying the controlled device, which is read from the transmission side identification code memory section. When the controlled device specified by the identification code data that has received the remote control signal is controlled, the identification code data stored in the transmission side identification code memory unit and the reception provided in the controlled device prior to the control are performed. The remote controller is designed to automatically set the identification code that matches the identification code data stored in the side identification code memory unit without the user of the controlled device being aware of it. An object is to provide a control device.

[0008]

In order to achieve the above object, a remote control device according to the present invention reads and reads identification code data for identifying a controlled device, which is stored in a transmission side identification code memory section. An operation control unit that forms a remote control signal corresponding to a data group including the issued identification code data, a transmission unit that transmits the remote control signal obtained from the operation control unit, and a transmission side that is derived from the operation control unit. An external connection terminal, wherein the transmission-side external connection terminal is provided in a controlled device including a reception section for receiving a remote control signal transmitted from the transmission section and a reception-side identification code memory section. When connected to the terminal, the operation control section stores identification code data for identifying the controlled device, which is stored in one of the transmission side identification code memory section and the reception side identification code memory section. , Are stored in the other of the sender identification code memory section and the receiving side the identification code memory unit,
It is assumed that the identification code is set.

[0009]

In such a remote control device according to the present invention, for example, when the entire device is mounted on the controlled device,
The transmission side external connection terminal is brought into a state of being connected to the reception side external connection terminal provided in the controlled device. Then, each time the transmission-side external connection terminal is connected to the reception-side external connection terminal, the operation control section causes the identification code data stored in advance in the reception-side identification code memory section provided in the controlled device to be changed. The operation that is read and stored in the transmission side identification code memory section, or the identification code data that is stored in advance in the transmission side identification code memory section is read and the reception side identification code provided in the controlled device The operation stored in the memory unit is automatically performed. Therefore, when the entire device is attached to the controlled device, the identification code data stored in the transmission side identification code memory unit and the identification code data stored in the reception side identification code memory unit provided in the controlled device The setting of the identification code that makes it coincide with is automatically performed without making the user of the controlled device aware of it.
