Hour chime clock
摘要:
An hour chime clock has an hour-indicating hand and a plurality of display units disposed circumferentially around the hour-indicating hand at different hour positions. The display units are displaceable between two positions to display either an ornament or an hour numeral. At each hour, a melody chimes and the display units undergo a predetermined pattern of movements. After chiming the hour, the display unit at the present hour position is placed in a different display state from the display state of all the other display units.
