| 摘要 | PURPOSE:To obtain an easy-to-handle direction indicator that requires no power source by supporting the 1st and 2nd solar cells rotatable on an axis and by providing the 1st and 2nd coils that generate a turning force with currents supplied from the cells and magnetic fluxes. CONSTITUTION:Supporting frame 1 is supported being rotatably on axis 2 and to this supporting frame, the 1st and 2nd partially-cylindrical solar cells 3 and 4 are so fitted that the photodetection surfaces outside of plane 5 containing the core of axis 2 will be symmetric. A magnet consists of concentric columnar N pole 6 and S pole 7, the N and S poles and axis 2 are concentric and cylindrical gap 8 where magnetic flux passes in the radius direction is formed. Further, the 1st and 2nd coils 9 and 10, positioned in gap 8, are fitted to supporting frame 1. Those 1st and 2nd coils 9 and 10 are connected to the 1st and 2nd cells 3 and 4 to generate turning forces opposite in direction. Thus, the handling is facilitated and the need for power sources is eliminated. | ||||||
