Claims (1)

[Scope of Claim for Utility Model Registration] A dome having a display section showing an east-west direction and a projection surface facing south on a horizontal plane, and a north-south direction shown in a vertical plane perpendicular to the east-west display line of the dome. It has a display section, and displays the time of the day from 1 a.m. clockwise from the bidirectional display section at equal intervals over the entire circumference, and tilts at an angle (α) corresponding to the inclination of the celestial equator with respect to the horizon. A base is provided with a time display board, which is rotatable around the center of the time display board, and dates from January to December are sequentially displayed in a counterclockwise direction at equal intervals over the entire circumference. a main date plate, which is provided integrally with the main date plate and displays the same date at the same angular position corresponding to the date on the main date plate;
At an angle (β) with respect to the time display plate in order to set the mid-south altitude of the sun's orbit as seen from the earth at the angle (α) and the ecliptic inclination (β) at a position where the summer solstice and winter solstice lines face due south. It has a plate with a slit that is inclined, and a date indicator that is rotatably provided around the center of the plate with a slit and indicates the date of the plate with a slit, and a date indicating part that is located inside at the same angular position as the date indicator. comprising a solar projection tube that projects a light source onto a projection surface of the dome;
A solar projector in which the moon phase is sequentially displayed in a counterclockwise direction around the entire circumference, with O at the same angular position as the sun projection tube at the rotation center opening, and 15 at the angular position 18 [° from the sun projection tube;
A lunar age sheet that is fixed to the rotation center opening of the solar projector by forming a lunar hole in the shape of the moon corresponding to each lunar age at the same angular position as the lunar age display except for lunar age 0, and this lunar age sheet. a lunar projection which is rotatably provided at the center of rotation of the solar projector and is selectively located in each of the lunar holes to project an internal light source onto the projection surface of the dome through each of the lunar holes; Projection observation of the sun and moon comprising a moon projector having holes: Equipment.
