Clock-type device for observing changes in the moon, sun and stars

摘要

The present invention relates to a clock-type device capable of observing changes in the moon, sun, and stars, and specifically, has a circular market with one rotation at 24 hours and two division scales displayed at the same angle with respect to the center. In a clock-type device, a plurality of concentric circles having an arbitrary diameter are formed with respect to the center, and the first concentric circle having the shortest diameter from the center is the orbit around the moon, the second concentric circle outside the first concentric circle is the orbit around the sun, The outermost third concentric circle is set to represent the diurnal orbit of the vernal equinox, so that anyone can easily see the movement of many objects in outer space, planetary movements, the concept of poetry, the movement of the constellations, the phase change of the moon, the change of seasons, etc. The present invention relates to a clock-type device that can observe the change of month, sun and season so that it can be known using a simple operation button.;According to the present invention, it is possible to understand the principles and concepts of the celestial body more easily by implementing inexpensive and universal equipments on the clock-type device that show the interrelationship between the sun, moon and stars, and especially the concept of time and the change of the four seasons and constellations. There is an effect that can be easily understood, and when the clock-type device according to the present invention is used as an educational tool in an institution that teaches the movement of the celestial body, such as a school, there is an effect that can be widely used as an inexpensive and practical equipment.;In addition, the operation is simpler and more versatile than the conventional complex devices, so that the movement of major celestial bodies can be observed at the same time.
