<p>A rotating display element (D) which is provided with a display surface member having a plurality of display surfaces F1-F4 which are selected by rotating the display surface member, and a display unit which uses the display element. The display surface member of the rotating display element (D) has incorporated therein a permanent magnet type motor mechanism and is driven by the permanent magnet type motor mechanism. The rotor (R) of the permanent magnet type motor mechanism has first and second double-pole permanent magnet members (M1, M2), and its stator (S) has first and second magnetic members having wound thereon first and second exciting windings (L,, L2), respectively. The display (D) unit has first and second power supply means (J1, J2) for supplying power to the first exciting winding (L1) of the permanent magnet type motor mechanism and third and fourth power supply means (J3, J4) for supplying power to the second exciting winding (L2). The plurality of display surfaces Fl-F2 of the display surface member can selectively be directed to the front by supplying power to the first exciting winding (L1) via the first or second power supply means (J1, J2) and by supplying power to the second exciting winding (L2) via the third or fourth power supply means (J3, J4). A display panel can be constituted by arranging, in a matrix form, a number of such display units each empolying the rotating display element.</p> |
