| titleOfInvention | Planetary system studying tools capable of simultaneously measuring tine, seasons and altitude of sun |
| abstract | PURPOSE: A celestial body teaching aid is provided to constantly measure time, term, and altitude by constantly maintaining the cross point of a projection. CONSTITUTION: The upper side of a reference surface(10) is open and the lower side thereof is hemispheric. An indication unit indicates a time line(21), a solar term line(22), and an altitude line(23) on the reference surface. An enlarging unit(30) enlarges the upper end of the reference surface to the outside. A projection unit(40) is detachably installed in the four minutes location unit of the enlarging unit. |
