EDUCATIONAL CLOCK CAPABLE OF ACTIVELY CALCULATING A GAP ANGLE POSSESSIVELY BY USING AN ANGLE HAND

摘要

PURPOSE: An educational clock is provided to have an educational effect by calculating an angle between an hour hand and a minute hand of a clock.;CONSTITUTION: A base plate(100) rotates an hour hand and a minute hand along an upper side. An angle hand(500) rotates around the upper side of the base plate to measure a gap angle between the hour hand and the minute hand. The angle hand helps measuring the gap angle of an hour display unit indicating the hour hand and a fixed time which is adjacent to the hour hand, by separating the hour display unit, which indicates each fixed time, into fixed angle units.;COPYRIGHT KIPO 2013
