PURPOSE:To make separate parts for display of ante meridiem and post meridiem unnecessary, by providing a display, by which ante meridiem and post meridiem are distinguished from each other, on a 24-hour wheel in the alarm clock where a hour unlocking wheel and a minute unlocking wheel are provided for the 24-hour wheel and a 1-hour wheel. CONSTITUTION:A minute unlocking wheel 17 and a hour unlocking wheel 18 are provided for 1-hour wheel 12 and a 24-hour wheel 14 respectively; and when an aimed time comes, an alarm equipment is operated by switch mechanisms provided between them. Numbers 14a 1-24, AM and PM or classification by coloring on the 24-hour wheel 14 are seen through a display window 10a of an alarm mechanism part 2 to distinguish ante meridiem and post meridiem from each other, thus preventing ante meridiem and post meridiem from beig set erroneously. |
