Automatic Revolution Apparatus of a Globe and Lelestial Globe

摘要

An automatic revolution apparatus is disclosed. An automatic revolution apparatus comprises a celestial globe of trans-=parent material fixedly installed on an upper surface of a revolution plate rotated by a revolution shaft; a globe of transparent material provided within the celestial globe and rotated by a rotation shaft installed at the angle of 66.5° with respect to the horizontal direction, with the standard map of the world displayed thereon; a revolution device installed within an upper and lower cover to rotate the revolution shaft; a rotation device installed within the revolution plate to rotate the rotation shaft; a celestial globe view horizon provided within the celestial globe to be the horizon of an observer; a zenith display part vertically provided in a center of the celestial globe view horizon to display the observer's position; and a manual operation knob installed at an end of the rotation shaft for a user to rotate the globe manually. An object of the present invention devised to solve the problem is to provide an automatic revolution apparatus of a globe and celestial globe which can present the earth position, seen from the sun and other stars, and can enhance students scientific thinking power to comprehend the revolution of the universe spatially and three-dimensionally.
