Abstract
PURPOSE: To enable to set the alarm time in a short time, by providing the first and second detection wheels to detect the phase of the gears of hour and minute unit, and the third detection means in interlocking with the leaf having the projection at a part of the minute digit leaf with a given minute interval.
CONSTITUTION: The detection lever 27 is rotationable to the shaft 28 and has the first arm 27a related to the minute and hour detection plates 25, 26, and the second arm 27b, and also has the pin 27c operating the first switch SW1. The second switch SW2 is in interlocking with the right projection of the third minute leaf 6c and the fourth leaf 6d. When alarm unit is desired to be in use, the third switch SW3 is ON and the minute gist drum 20 and the hour gist drum are set to the desired time by turning the knob 15. Thus, the phase of the cams 25a, 26a of the minute detection plate 25 and hour detection plate 26 is determined. When the leaf of 59min. is inverted to 00min., since the projection 61 restricting the switch SW2 is absent, the switch SW2 is ON with spring force and the buzzer B is activated.
