DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a combination of a globe and a celestial sphere. The celestial sphere is illuminated from the inside to project a constellation on the surface of a wall or the like. It relates to a globe with a celestial sphere that can be made.

[0002]

2. Description of the Related Art Conventionally, as a globe with a celestial sphere, for example,
There is one as seen in Japanese Utility Model Publication No. 1-28539 related to the applicant's invention. The globe with a celestial sphere has a configuration in which a globe and a celestial sphere simulating a celestial body are supported on a bow having two arc-shaped portions erected on a pedestal so as to rotate separately from each other. Functions can be demonstrated.

[0003]

However, the globe with the celestial sphere can learn and understand the realities of the globe as a globe and the celestial sphere as a celestial sphere. Many constellations are drawn and can be understood only in the superficial range, and it is difficult to learn and understand the cosmic view like a planetarium and the earth as a single star in the universe, and to learn and interest in astronomy. There was a problem that it was not enough to exalt.
Therefore, the present invention has been made to solve such a problem, by illuminating the celestial sphere from the inside and drawing the constellation of the surface on a wall or the like so that the globe can be enjoyed therein,
The purpose of the present invention is to provide a globe with a celestial sphere that can enhance learning and interest in astronomy.

[0004]

In order to achieve the above object, a globe with a celestial sphere according to the present invention has a support rod erected on a base, and the globe and the celestial sphere are vertically moved via the support rod. Deploy. The globe and the celestial sphere are pivotally supported so as to be rotatable about the same axis, and a motor is provided on the base as driving means. Further, the celestial sphere is formed of a light-transmitting hollow sphere, and a light bulb is built therein. Then, the motor is driven to rotate the globe and the celestial sphere, and at the same time, emits light from the bulb. As a result, constellations on the surface of the celestial sphere are drawn on the surface of a wall or the like, and the globe is rotated against the background, so that the planetarium can be enjoyed and the understanding of astronomy is deepened.

[0005] Further, by installing an audio device including an IC music box substrate and a speaker on a base to generate sound related to the universe, the sound effect is squared with the three-dimensional representation of the earth and constellations, thereby enhancing the sense of presence. be able to.
