Abstract

A remote control device for an electronic appliance includes a plurality of channel number inputting keys for inputting a channel number and a further key different from the plurality of channel number inputting keys. When the further key was operated, a CPU determines whether any one of the plurality of channel number inputting keys was operated directly before the further key was operated. If so, the CPU sends the electronic appliance a first remote control code related to channel selection. If not, the CPU sends the electronic appliance a second remote control code which controls a function different from the channel selection. In this case, the sole key fulfills the two functions to reduce the number of keys.

Claims

1. A remote control device for an electronic appliance, comprising:

a plurality of channel number inputting keys for inputting a channel number to the remote control device;

channel number code sending means for, when any one of said plurality of channel number inputting keys is operated, sending a channel number code corresponding to the operated channel number inputting key;

an end code sending key;

end code sending means for sending an end code which represents that said channel number code sending means has finished sending the channel number code, in response to operation of said end code sending key;

a further key different from said plurality of channel number inputting keys and said end code sending key, said further key corresponding to a function;

determining means for, when said further key is operated, determining whether any one of said plurality of channel number inputting keys was operated to send the corresponding channel number code, directly before said further key has been operated;

control means for controlling said end code sending means to send the end code for channel selection when said determining means determines that one of said plurality of channel number inputting keys was operated directly before said further key has been operated; and

function executing means for executing the function corresponding to said further key after said control means has controlled said end code sending means to send the end code.

2. A remote control device according to claim 1, further comprising:

timekeeping means for measuring the current time; and

current time display means for displaying the current time.

3. A remote control device according to claim 1, comprising a case to which a band is attached for wearing said remote control device on a wrist, said case enclosing respective elements of said remote control device therein.

4. A remote control device according to claim 1, further comprising:

means for controlling said end code sending means to send the end code, when said further key and said end code sending key are not operated within a given time after any one of said plurality of channel number inputting keys was operated.

5. A remote control device according to claim 1, wherein said determining means comprises operation storage means for storing the fact that any one of said plurality of channel number inputting keys was operated when that fact occurred, said operation storage means being cleared when said further key is operated.

6. A remote control device according to claim 1, wherein said control means sends a remote control code, using infrared rays.

7. A remote control device according to claim 6, further comprising:

display means for displaying a remote control code sent by said control means.
