Abstract: To provide a remote controller into which a kitchen timer function and a television control function are integrated so that mutual cooperation between cooking and television watching is simplified. As shown in FIG. 5, when executing a kitchen timer function using a remote controller 50, a user depresses a function selection button 71 predetermined number of times to select the kitchen timer function. Next, the user depresses a first time period setting button 72 to set a “minute” unit portion of the desirable time period and then depresses a second time period setting button 73 to set a “second” unit portion of the time period. Finally, the user depresses a SET/STOP button 74 and the kitchen timer function starts. When the timer counts down and its display indicates “0 minute and 0 second”, a buzzer 58 of a remote control section 56 gives an alarm sound. Further, the remote control section 56 switches the display of a liquid crystal display section 54 to a clock time display.
