From the above-mentioned i-th state of the display element E in which the i- _th display surface F i of the display surface member D of the display element E faces forward, the stator of the permanent magnet type motor mechanism Q is changed. excitation winding L i-th is wound on the magnetic body B _i of the i th ST
_If the electric power is supplied to _i for a short time through the above-mentioned electric power supply means J _i constituting the drive unit G, the i-th magnetic body B of the stator ST of the permanent magnet type motor mechanism Q is supplied. _i pole P _i of is magnetized to the S pole. However, at this time, the first magnetized magnetic pole 12N of the magnet body M forming the rotor RT of the permanent magnet type motor mechanism Q faces the magnetic pole P _i of the _i- th magnetic body B _i . Therefore, the rotating torque is not substantially generated in the magnet body M in both the clockwise direction and the counterclockwise direction. Therefore, the rotor RT of the permanent magnet type motor mechanism Q is
Does not rotate substantially clockwise or counterclockwise,
Therefore, the above-mentioned i-th state of the display element E is maintained.

From the above, the first display element E having an odd number of display surfaces according to the present invention shown in FIGS.
Using examples, according to the first embodiment of the display device according to the present invention, the display surface F _i of the display facepiece D of the display element E is directed to the front, from the state of the _i-th display element E , A j-th excitation winding L _j wound around the j-th magnetic body B _j of the stator RT of the permanent magnet type motor mechanism Q, and the j-th power source constituting the drive unit G. It is possible to easily obtain the j-th state of the display element E in which the j-th display surface F _j of the display surface member D of the display element E faces forward by simply supplying power through the supply means J _j. You can

From the i-th state of the display element E in which the i- _th display surface F i of the display surface body D of the display element E faces forward, the j-th display surface of the display surface body D of the display element E is changed. After obtaining the j-th state of the display element E with F _j facing forward, the j-th magnetic body B _j of the stator ST of the permanent magnet type motor mechanism Q is obtained.
Even if the supply of power to the _j-th exciting winding L _j wound above is cut off, (A) the first magnet body M of the rotor RT constituting the motor mechanism Q is Magnetizing magnetic pole 12N (N pole in this embodiment)
Acts on the magnetic pole P _j of the j-th magnetic body B _j of the stator ST which constitutes the motor mechanism Q, and (B) the second magnetized magnetic pole 12S of the magnet M (this embodiment).

2) Magnetic material B _{(j- (n + 1) / 2)} magnetic pole P _{(j- (n + 1) / 2 )} and (j- (n + 1) / 2 + 1) magnetic material B
_Since it acts on the magnetic pole P _{(j- (n + 1) / 2 + 1)} of _{(j- (n + 1) / 2 + 1)} , there is no need to specially provide any additional means, and The j-th state of the display element E, in which the display surface F _{j of j} is facing forward, causes substantially no displacement,
It is surely kept.

Therefore, the j-th display surface F of the display surface member D
_{The j-th} state of the display element E in which j is facing forward is
It can be secured without power consumption.

Further, since the display surface body D of the display element E has the state in which the permanent magnet type motor mechanism Q for rotating the display element E is provided, the rotation for rotating the display surface body D is performed. It is not necessary to separately prepare the mechanism separately from the display element E.

Although detailed description is omitted, power is supplied to the excitation winding of the permanent magnet type motor mechanism Q by the display element and the display element disclosed in the above-mentioned JP-A-62-79495. It is easier than a display device using it.

Furthermore, the rotor RT of the permanent magnet type motor mechanism Q needs only one magnet body M having N and S poles. Therefore, the permanent magnet type motor mechanism Q is simple, JP-A-62-79495 discloses an operation for bringing a desired one of an odd number of display surfaces of the display surface member D into a state in which the rotor RT is lightened and the rotor RT is also lightened. It is possible to perform the operation at a higher speed than the case of the existing display element and the display device using the same.

The display device according to the present invention shown in FIGS. 1 to 12 uses a large number of them, and a large number of the display elements E are arranged in a matrix on a common plane or curved surface to form a panel. If it is manufactured, it is possible to selectively direct the plurality of display surfaces of the plurality of display elements E to the front face by the driving device of the plurality of display devices, so that characters, symbolic figures, patterns on the panel are displayed. Etc. can be displayed. Therefore, it can be used for, for example, an advertising panel, a traffic sign, and the like.
