PURPOSE:To enlarge a time alarm indicating character of a time alarm setting wheel and to increase the width of a contact by enabling the setting of an alarm of 24-hours type with a 12-hours indication by switching the setting of AM and PM. CONSTITUTION:When an AM-PM setting piece 96 is operated, an AM-PM setting drum 95 is rotated, and thereby AM or PM is indicated, while AM or PM is set by an AM setting contact 101 or a PM setting contact 102, and by an AM- PM setting common contact 103. Accordingly, an alarm time is indicated with a 12-hour unit by a time alarm setting wheel 64', and time setting fixed contacts 99 are reduced only to twelve in the same number as of minute alarm setting made every 5min. By this constitution, intervals between time alarm indicating characters and the fixed contacts of the time alarm setting wheel can be made larger than those in the case of 24-hour indication. Thereby the reliability on processing, etc. is improved and the setting of the alarm is facilitated. |
