Remote controller

1. A remote controller comprising:

at least one first input unit that macro-controls predetermined remotely controlled devices including signal source devices;

a plurality of second input units that select the signal source devices;

a memory unit that stores a plurality of remote control codes for remotely controlling the remotely controlled devices;

a transmitting unit that externally transmits the remote control codes; and

a control unit that, when the first input unit is operated, outputs the remote control codes for remotely controlling the plurality of remotely controlled devices to the transmitting unit, and causes the transmitting unit to externally transmit the codes, wherein

when the first input unit and one of the second input units are operated in a predetermined manner, the signal source device to be remotely controlled by the first input unit is changed to the signal source device that has been selected by the operated one of the second input units.

2. The remote controller according to claim 1 , wherein

said memory unit further stores a macro-control process sequence that is associated with said first input unit, the macro-control process sequence including key codes for operation keys for remotely controlling said remotely controlled devices in a predetermined order, and

said control unit:

when said first input unit is operated, carries out one of a remote control processing carried out in the same manner as in a case in which operation keys corresponding to the key codes included in the macro-control process sequence that is associated with the operated first input unit are operated, and a predetermined remote control processing, and

when the first input unit and the one of said second input units are operated in the predetermined manner, changes a key code in the macro-control process sequence for remotely controlling said signal source device to a key code for remotely controlling the signal source device that has been selected by the operated one of the second input units.

3. The remote controller according to claim 1 , further comprising:

a third input unit that turns off power of said remotely controlled devices that have been turned on through a macro-control operation by said first input unit, wherein

said control unit:

when the third input unit is operated, outputs the remote control codes for turning off power of the remotely controlled devices that have been turned on through the macro-control operation by the first input unit to the transmitting unit, and causes the transmitting unit to externally transmit the codes, and

when one of the first input unit and the third input unit is operated together with the second input unit in the predetermined manner, changes the signal source device to be turned off by the third input unit to the signal source device that has been selected by the operated one of the second input units.

4. The remote controller according to claim 1 used in an audio-visual system including an audio-visual amplifier as one of said remotely controlled devices, the audio-visual amplifier having an input selector for selecting one of the signal source devices to which one of an audio signal and a video signal is inputted, wherein

said second input units are operation keys for switching the input selector of the audio-visual amplifier, and

the signal source devices selected by the second input units are associated with the operation keys.

5. A remote controller comprising:

a plurality of first input units that turns on power of a plurality of remotely controlled devices;

a second input unit that turns off power of the plurality of remotely controlled devices;

a memory unit that stores a plurality of remote control codes for remotely controlling the remotely controlled devices;

a transmitting unit that externally transmits the remote control codes; and

a control unit that outputs the remote control codes to the transmitting unit and causes the transmitting unit to externally transmit the codes, wherein

the control unit:

when any of the plurality of first input units is operated, outputs remote control codes for turning on power of predetermined remotely controlled devices associated with the operated first input unit to the transmitting unit, and causes the transmitting unit to externally transmit the codes, and

when the second input unit is operated, outputs remote control codes for turning off power of the remotely controlled devices that have been turned on by the first input unit that has been operated last time to the transmitting unit, and causes the transmitting unit to externally transmit the codes.

6. The remote controller according to claim 5 , wherein

said memory unit further stores macro-control process sequences that are associated with said first input units, each macro-control process sequence including key codes for operation keys in a predetermined order, the operation keys being for remotely controlling said remotely controlled devices, and

said control unit:

when any of said first input unit is operated, carries out one of a remote control processing in the same manner as in a case in which the operation keys corresponding to the key codes included in the macro-control process sequence that is associated with the operated first input unit are operated, and a predetermined remote control processing, and

when said second input unit is operated, turns off power of the remotely controlled devices whose key codes for turning on power of the remotely controlled devices are included in the macro-control process sequence that is associated with said last operated first input unit.

7. The remote controller according to claim 6 , wherein

when said macro-control process sequence associated with said last operated first input unit is modified after an operation of the sequence,

said control unit, when said second input unit is operated, turns off power only of predetermined remotely controlled devices regardless of the macro-control process sequence associated with the last operated first input unit.
