Display element with an odd number of display surfaces and display unit using the same

摘要

In display comprising a display surface member with a plurality of display surfaces, and a permanent magnet type motor mechanism composed of a stator having magnetic members each forming a magnetic pole at one free end and excitation windings wound on the magnetic members and a rotor having a magnet member with a double-pole permanent magnet, the number of display surfaces of the display surface member is three or more odd number; the numbers of magnetic members and excitation windings of the rotor are also odd in accordance with the number of display surfaces and the magnet member of the rotor has a first magnetic pole opposed to the magnetic pole of one of the odd number of magnetic members and a second magnetic pole opposed to the magnetic poles of the other two adjacent magnetic members.
