PURPOSE:To enable the easy discrimination and grasping of alarm content by a user, by informing a past or present alarm sound and a past/present simultaneous alarm sound in a different mode. CONSTITUTION:After the set time (t) of a monomultivibrator 5 is elapsed, output L2 is turned OFF and MPU3 is brought to a wt. state. When key input data sent to MPU3 is alarm generating time setting input, it is sent to RAM7 through L4, a time counting part 4, DL and AL to be stored therein. The time counting part 4 compares a set time and a counted time and, when both times are coincided, alarm generation is informed to MPU3 through a signal line L5 while MPU3 reads set time information from RAM7 through AL and DL according to the program in ROM6 and sends the same to interface 10 and display buffer 8. The set time stored in the display buffer 8 is displayed by a display device 9. |
