Earth globe.

摘要

An earth globe includes a base and a hollow globe body made of translucent material and having a spherical configuration corresponding substantially to the earth. A first support mechanism serves to rotatably support the globe body relative to the base around a first axis corresponding substantially to the earth axis. An illumination device and a shading device are disposed within the globe body. The shading device serves to shade light from the illumination device over a substantially half region of the globe body. A second support mechanism is provided to rotatably support the shading device relative to the globe body around a second axis corresponding substantially to an axis perpendicular to the orbital plane of revolution of the earth around the sun. A first and a second drive device are provided to rotate the globe body around the first axis at a first rotational speed and to rotate the shading device around the second axis at a second rotational speed different from the first rotational speed, respectively. <IMAGE>
