Claims

[Scope of utility model registration request]

The circular disk A is divided into n equal sectors A1, A2, A3...
For each of ..., draw constellations in the northern sky from red radius 0 o'clock to red radius 24 o'clock, with the radial direction of the sector as the direction of the equideclination line, and a disk that has a radius larger than disk A and shares the center with disk A. B is placed below A, and the ring shape of disk B viewed from above is divided into m equal sectors B1, B2, B.
3...Draw the constellations in the southern sky from red radius 0 o'clock to red radius 24 o'clock, with the radial direction of the fan shape as the direction of the equideclination line, and divide the back surface of the disk B into m equal parts D1
, D2, D3..., draw constellations in the northern sky from red radius 0 o'clock to red radius 24 o'clock, with the radial direction of the fan shape as the direction of the equideclination line, and draw n around the surface of the disk A.
Fill in the yearly month and day scale M, and place a fixed plate C on top of the circular plate A, which has a visible window N for the northern sky, a visible window S for the southern sky, and a visible time scale window T, under the back side of the circular plate B. A fixed plate E with a visible window Q directly above is placed on top of the
Connect fixed plate E and fixed plate C to disk B via a spacer.
A constellation that has a mechanical or electrical device that connects A and B so that when disk A is rotated m counterclockwise, disk B rotates clockwise n times.
