Abstract

A remote control device having a learning function includes a manipulating section having a plurality of control keys; a first read only memory having storage portions which correspond to the keys and store informations for remote control signals in advance; a reception section for receiving a remote control signal; a mode changeover section for shifting the operation mode of the device between a reception mode and a transmission mode; an erasable second memory which has storage portions corresponding to the control keys of the manipulating section; a writing section for writing the information of the remote control signal received by the reception section into the storage portion of the second memory corresponding to the manipulated control key of the manipulating section when the operation mode is shifted to the reception mode; a reading section for reading the information stored in the storage portions of the first and second memory, which correspond to the manipulated control key of the manipulating section, in response to the manipulation of the key when the operation mode is shifted to the transmission mode; and a transmission section for transmitting the remote control signals formed from the information read by the reading section.

Claims

1. In a learning remote control device comprising a manipulating section having a plurality of control keys, a first memory means having storage portions which correspond to said control keys, a reception means for receiving a remote control signal from the outside of said device, and a mode changeover means for shifting the operation mode of said device between a reception mode and a transmission mode, the improvement comprising:

an erasable second memory means which has storage portions corresponding to said control keys of said manipulating section, said control keys being the same as those corresponding to said storage portions of said first memory means;

a writing means, operable when said operation mode is shifted to said reception mode by said changeover means, for writing the information of said remote control signal received by said reception means into the storage portion of said second memory means, said written information being stored in a storage portion of said second memory means which corresponds to a manipulated one of said control keys of said manipulating section;

a reading means, operable when said operation mode is shifted to said transmission mode by said mode changeover means and the one of said control keys is manipulated, for reading the information stored in those storage portions of said first and second memory means which correspond to the manipulated one of said control keys of said manipulating section; and

a transmission means for transmitting the remote control signals respectively corresponding to said information read from said first and second memory means by said reading means and wherein said first memory means is a read-only type memory which stores predetermined information representing remote control signals for operating a first appliance, and wherein said second memory means stores information representing received remote control signals for operating a second appliance which is different from the first appliance.

2. The remote control device of claim 1, wherein said first memory means comprises a ROM, and said erasable second memory means comprises a RAM.

3. The remote control device of claim 1, further comprising display means for prompting a user after a remote control signal is received by said reception means and stored in said erasable second memory means by said writing means.

4. A learning remote control device comprising a manipulating section having a plurality of control keys, a first memory means having storage portions corresponding to said plurality of control keys, respectively, reception means for receiving a remote control signal, and a mode changeover means for shifting the operation mode of said device between a reception mode and a transmission mode, the improvement comprising:

a second memory means having storage portions corresponding to said plurality of control keys, respectively, so that the storage portions of said memory means correspond respectively to the storage portions of said first memory means;

a writing means, coupled to receive an output of said reception means, for writing information representing the received remote control signal into a storage portion of said second memory means which corresponds to the manipulated control key of said manipulating section when said operation mode is shifted to said reception mode by said mode changeover means;

reading means, coupled to receive an output of said first and second memory means, for reading the information stored in the storage portions of said first and second memory means, the storage portions of the read information corresponding to the manipulated control key of said manipulating section, said reading means only being operable when the operation mode of the device is switched to the transmission mode by said mode changeover means; and

transmission means, coupled to receive an output of said reading means, for transmitting the remote control signals corresponding to said information read by said reading means, and wherein said first memory means is a read-only type memory which stores predetermined information representing remote control signals for operation a first appliance, and wherein said second memory means stores information representing received remote control signals for operating a second appliance which is different from the first appliance, whereby a manipulation of a single control key, during the transmission mode of operation by the device causes the read remote control signals from the first and second memory means to be transmitted by said transmission means.
