Claims

[Claims for Utility Model Registration] 1. A four-sided display in which a rotary body 7 having four display surfaces is rotatably supported by a rotary shaft 8, which is provided integrally with the rotary body 7; Excited to S pole and N pole in the direction of both ends 8a and 8b of 8,
4 arranged at angular intervals of 90° around the rotation axis 8
two electromagnets 17, 18, 19, 20, a predetermined distance apart from the electromagnets 17, 18, 19, 20 in the direction of both ends 8a, 8b of the rotating shaft 8, and a N pole of the electromagnets 17, 18, 19, 20 or S
A four-sided display comprising permanent magnets each having two magnetic poles acting on the poles and located in the same plane orthogonal to the rotation axis 8. 2. The permanent magnet has a substantially fan-shaped planar outline and is composed of a pair of first and second permanent magnets facing each other with magnetic poles in the direction of both ends of the rotating shaft 8. The four-sided display according to claim 1.
