    • PURPOSE:To see a constellation of a specified time of a year at a glance, by interlocking a rotation of a revolving shaft of a clock and a rotation of a constellation plate, so that the constellation place performs one rotation by one day of a fixed star day. CONSTITUTION:A star group which can be seen over one year in a specified place in Japan is drawn successively along the circumferential direction on a discoid constellation plate 1, and many teeth 2 engaged with a driving gear 11 are formed like a gear on its outside circumferential face. A surface plate 4 and a back plate 5 of a body 3 are connected as one body by holding a prescribed interval by a connector 6, an elliptical window 7 is provided on the surface plate 4, and the constellation plate concerned 1 is supported so as to be freely rotatable through a supporting shaft 8 between the surface plate 4 and the back plate 5 of the body 3, so that the about lower half part of the constellation plate 1 can be seen from the window concerned 7. The size of the window 7 to the constellation plate 1 corresponds to a field of view which can be observed when looking up to the star group in a night sky from on the earth.
    • 目的:通过将时钟的旋转轴的旋转和星座板的旋转相互联动,一目了然地看到一年中指定时间的星座,使得星座位置一天旋转固定 明星之日。 构成:在圆盘状星座板1上沿着圆周方向连续地绘制在日本特定地方可以看到的一年以上的星星组,并且与驱动齿轮11啮合的许多齿2在其外部形成为齿轮 圆周面。 主体3的表面板4和背板5通过连接器6保持规定的间隔作为一体连接,在表面板4上设置有椭圆窗7,并且所述星座板1被支撑为 可以通过主体3的表面板4和背板5之间的支撑轴8自由旋转,从而可以从相关窗口7看到星座板1的大约下半部分。窗口的尺寸 7到星座板1对应于在从地球上看夜空中的星团时可观察到的视场。
