The principle of the first embodiment of the display element E having five display surfaces according to the present invention and the structure of the first principle of the display device using the same according to the present invention are described above. Became clear.

According to the display device using the first embodiment of the display element E having five display surfaces according to the present invention having such a structure, the first to the first parts of the permanent magnet type motor mechanism Q are used. As described above, one of the _five magnetic bodies B _{1 to} B _{5 is} generally referred to as the i-th magnetic body B _i , and generally speaking, the first magnetic body B _i of the rotor RT is formed by the permanent magnet MB. Magnetic pole 21

2 + 1), and therefore, closely faces the magnetic pole P _{(i + 3)} of the (i + 3) th magnetic body B _{(i + 3)} , and (b) i becomes i = (5 + 1)
/ 2, and therefore i = 3, as shown in FIG. 11, the (i + (5-1) / 2) th, and therefore the (i

It is clear that the _i-th magnetic body B _(i-2) faces the magnetic pole P _(i-2) at the _i- th rotational position.

Also, the rotor R of the permanent magnet type motor mechanism Q
When T is in the i-th rotation position in this way, as shown in FIGS. 9 to 13, the i-th display surface F _i of the display surface body D forming the display element E is moved forward. It is also clear from the above description that the i-th state of the display element E, which is the orientation, is obtained.

Further, the first magnetic pole 12B of the rotor RT
Is closely opposed to the magnetic pole P ₁ of the i-th magnetic body B ₁ of the stator ST, and thus the i-th state of the display element E in which the i- _th display surface F _i of the display surface body D faces forward is From the obtained state, the i-th control signal C _{i is} output from the control signal generation circuit 24.

(B) When i is i ≧ 3, the (i−2) th magnetic body B
_Since it is opposed to the magnetic pole P _{(i-2) of (i-2)} , a rotational torque is generated in the rotor RT in the clockwise direction, so that (a) i of the first magnetic pole 12B is i ≦ In case of 4, i-th magnetic pole B
proximate opposed to the pole P _{(i + 1)} of the Tonariru to _i and clockwise (i + 1) of the magnetic member B _{(i + 1),} therefore, the display facepiece D (i

Further, the first magnetic pole 12B of the rotor RT is
The i-th state of the display element E in which the i- _th display surface F _i of the display surface member D faces forward is obtained because the magnetic pole P ₁ of the i-th magnetic member B ₁ of the stator ST is closely faced. From the control signal generation circuit 24, when (a) i is i ≦ 2, the (i + 3) th control signal C _{(i + 3)} is output from
In the case of> 2, if the (i−2) th control signal C _(i−2) is generated as “1” in binary display for a short time, (a) i is i ≦ 2. In the case of (i + 3) th power supply means J _{(i + 3)} , and when (b) i is i> 2, the (i-2) th power supply means J _(i-2) supplies power 20
Therefore, when (a) i is i ≦ 2, (b) i is applied to the i-th and (i + 3) th excitation windings L _i and L _{(i + 3)} of the stator ST.
Is i> 2, power is supplied to the _{i- th} and _{(i-2) th} excitation windings _Li and L _(i-2) of the stator ST for a short time, so that (a) i is i. When ≦ 2, as shown in FIGS. 15, 17 and 19, the i-th and the (i +) th of the stator ST are
3) Magnetic materials B _i and B _{(i + 3)} magnetic poles P _i and P _{(i + 3)}
However, when (b) i is i> 2, as shown in FIGS. 21 and 23, the i-th and (i−2) th magnetic bodies B of the stator ST are
The magnetic poles P _i and P _{(i-2) of i} and B _(i-2) are magnetized to the same polarity (N pole) as the first and second magnetic poles 12B and 12C for a short time, and at this time, Second magnetic pole 12C

_Since it is opposed to _(i-3) , counterclockwise rotation torque is generated in the rotor RT, and thus the first magnetic pole 12B
When (a) i is i <2, the magnetic pole P of the _{(i + 4) th} magnetic body B _{(i + 4)} adjacent to the i- _th magnetic pole B _i in the counterclockwise direction is
_{(i + 4)} close to each other, and accordingly, the _{(i + 4)}
4) The display element E in which the display surface F _{(i + 4)} faces forward is in the (i + 4) th state, the (i + 4) th state is maintained, and (b) i is i ≧ 2. In this case, the magnetic pole P of the _{(i-1) th} magnetic body B _(i-1) adjacent to the i- _th magnetic pole B _i in the counterclockwise direction
