PURPOSE:To carry out clear display even in a daylight. CONSTITUTION:A light emitting diode is assembled into one surface of multicolored polyhedron of a magnetic rotational display device 13, aimed for the display through rotational control of a colored surface. The turning on/out of the light emitting diode of the magnetic rotational display device 13 is controlled by a lighting control circuit 12. Magnetism for rotating the magnetic rotational display device 13 is generated by a magnetism generating circuit 15 by utilizing the principle of electromagnet. Control information relating rotational direction as well as of rotational number is output to the magnetism generating circuit 15 by a rotational control circuit 14. The entire display device is controlled by a display control circuit 11. |
