A timer set key is depressed and a set time is incremented a number of times, if it is determined that an incremented set time is equal to "OFF", then the processing proceeds and the incremented set time is displayed during a time period longer than about 100 milliseconds, which is a display time of a normal set time, e.g., about 500 milliseconds. Therefore, when the set time is successively incremented from the set time to the set time during the time that the timer set key is depressed, only "OFF" is displayed for a time period longer that those of other set times. |
