PURPOSE:To improve facility of timer function, by a method wherein, when the one timer set during operation of the other timer is rendered ineffective, an alarm is sounded. CONSTITUTION:When set control of a get-up timer is effected during setting of a go-to-bed timer, when an ignition time by the get-up timer set by a switch 3 is earlier than an extinguishing time set by the go-to-bed timer, an ineffective sound for the get-up timer is alarmed from a buzzer 10. Thus, a user varies a set time of get-up ignition. When set control of the go-to-bed timer is effected during set of the get-up timer, when an extinguishing time by making of a go-to-bed switch 5 is later than an ignition time by the get-up timer, an ineffective sound for the go-to-bed timer is alarmed from the buzzer 10. Thus, a user effects set control of the go-to-bed timer again. |
