The structure of an example of a display device using a rotary display element according to the present invention has been roughly clarified above. Next, the details of the structure of the example will be described together with its operation.

According to an exemplary configuration of the display device using the rotary display element according to the present invention described above, the rotor R constituting the motor mechanism Q has two bipolar permanent magnet bodies M1 attached to the rotating shaft 11. and M2, and the N and S poles of the bipolar permanent magnet M1 and the N8i and S of the 2Fi permanent magnet M2.
The poles maintain an angular interval of ±α° (however, α°=0° in the figure) when viewed around the rotation axis 11.

On the other hand, the stators S constituting the motor mechanism Q are arranged around the rotation @11, which acts on the N and S poles of the two-pole permanent magnet M1, with an angular spacing of 180° between them. Magnetic pole P1
and P2, and the magnetic body B1 acts on the N and S poles of the bipolar permanent magnet M2, around the rotating shaft 11, and the magnetic poles P1 and P2 of the bipolar permanent magnet M1 and ±90''±α° and a magnetic body B2 having magnets ff1P3 and P4 arranged at an angular interval of 180°,
Then, the magnetic poles P1 and P2 of the magnetic body B1 are connected to the rotating shaft 11.
, and the magnetic poles P3 and P4 of the magnetic body B2 similarly extend around the axis of rotation 11 over an angular range of 90°.

Therefore, in the rotor R of the motor mechanism Q, the movable contacts C of the changeover switches W1 and W2 described above are in the position of the fixed contact d other than the fixed contacts a and b, and therefore the excitation winding of the stator S When power is not supplied to either L1 or L2, the N and S poles of the bipolar permanent magnet M1 are magnetic, as shown in FIGS. 5, 9, 12, and 15. Opposing one ends a of magnetic poles P1 and P2 of body B1, respectively,
The N pole and S pole of the bipolar permanent magnet M2 are respectively opposed to one end of the magnetic poles P3 and P4 of the magnetic body B2.
The above-mentioned first rotational position is taken, or the sixth rotational position is taken.
13 and 16, the N and S poles of the bipolar permanent magnet M1 are the magnetic poles P1 and P2 of the magnetic body B1.
The above-mentioned fourth rotational position is such that the two ends of the permanent magnet M2 face each other, and the N and S poles of the two-pole permanent magnet M2 face the one ends a of the magnetic poles P4 and P3 of the magnetic body B2, respectively. Are you taking the figures 7, 10 and 1?
As shown in Fig. 7, the N and S poles of the bipolar permanent magnet M1 are opposite to the magnetic poles P2 and Pl of the magnetic body B1, respectively, and the N and S poles of the bipolar permanent magnet M2 are opposite to each other. Magnetic material B2
8, 11, and 14, or a two-pole permanent The N and S poles of the magnet M1 are opposed to one ends a of the magnetic poles P2 and Pl of the magnetic body B1, respectively, and the two-pole permanent magnet M2
It takes the above-mentioned third rotational position in which the N and S poles of the magnetic body B2 are opposed to one end of the magnets ff1P4 and P3, respectively.

The reason is as follows.

That is, the rotor R is as shown in FIGS. 5, 9, and 9.

When the rotor R attempts to rotate counterclockwise from the above-described first rotational position shown in FIGS. 12 and 15, the N and S poles of the two-pole permanent magnet M1 become magnetic. Since the magnetic poles P1 and P2 of body B1 are not opposed to each other, 2
A rotational torque that prevents the rotor R from rotating counterclockwise is not generated in the polar permanent magnet M1, but the N and S poles of the bipolar permanent magnet M2 are the same as the magnetic pole P3 of the magnetic body B2. and P4, so the two-pole permanent magnet M
2, a rotational torque is generated that prevents the rotor R from rotating counterclockwise. Further, when the rotor R starts to rotate clockwise from the state where the rotor R is in the above-mentioned first rotation position shown in FIGS. 5, 9, 12, and 15, , since the N and S poles of the two-pole permanent magnet M2 do not face the magnetic poles P3 and P4 of the magnetic body B2, the rotor R cannot rotate clockwise in the two-pole permanent magnet M2. However, since the N and S poles of the bipolar permanent magnet M1 do not oppose the magnetic poles P1 and P2 of the magnetic body B1, the rotor A rotational torque is generated that prevents R from rotating clockwise.

Moreover, if the rotor R does not rotate clockwise from the state in which the rotor R is in the above-mentioned fourth rotation position shown in FIGS. 6, 13, and 16, then Since the N and S poles of the magnet M1 do not face the magnetic poles P1 and P2 of the magnetic body B1, the two-pole permanent magnet M1 prevents the rotor R from rotating clockwise. No rotational torque is generated, but since the N and S poles of the two-pole permanent magnet M2 do not oppose the magnetic poles P4 and P3 of the magnetic body B2, the rotor R is rotated clockwise to the two-pole permanent magnet M2. A rotational torque is generated that prevents the product from rotating. Furthermore, if the rotor R does not rotate counterclockwise from the state in which the rotor R is in the above-mentioned fourth rotation position shown in FIGS. 6, 13, and 16, Since the N and S poles of the permanent magnet M2 do not face the magnetic poles P4 and F3 of the magnetic body B2, the two-pole permanent magnet M2 is
Although the rotational torque that prevents the trochanter R from rotating counterclockwise is not generated, the N and S poles of the bipolar permanent magnet M1 are not opposed to the magnetic poles P1 and F2 of the magnetic body B1. Therefore, a rotational torque that prevents the rotor R from rotating in the counterclockwise direction is generated in the two-pole permanent magnet M1.

Furthermore, from the state where the rotor R is in the above-mentioned second rotational position shown in FIGS. 7, 10, and 17, the rotor R
If it continues to rotate clockwise, the two-pole permanent magnet M1
Since the N and S poles of the magnetic body B1 do not face the magnetic poles P2 and Pl of the magnetic body B1, the rotational torque of the two-pole permanent magnet M1 that prevents the rotor R from rotating clockwise is Although it does not occur, 2 results are permanent...N and S poles of stone body M2
Since the poles are not opposed to the magnets 1 (iP3 and F4) of the magnetic body B2, a rotational torque that prevents the rotor R from rotating clockwise is generated in the two-pole permanent magnet M2. Furthermore, if the rotor R does not rotate counterclockwise from the state in which the rotor R is in the above-mentioned second rotation position shown in FIGS. 7, 10, and 17, Since the N and S poles of the permanent magnet M2 do not face the magnetic poles P3 and F4 of the magnetic body B2, the two-pole permanent magnet M2 is prevented from rotating the rotor R in the counterclockwise direction. Although no blocking torque is generated, the N and S poles of the two-pole permanent magnet M1 do not oppose the magnetic poles P2 and Pl of the magnetic body B1, so the rotor R is A rotational torque is generated that prevents full rotation in the counterclockwise direction.

Furthermore, the rotor R is shown in FIGS. 8, 11, and 14.
When the rotor R is rotated counterclockwise from the third rotational position shown in the figure, the N and S poles of the two-pole permanent magnet M1 become the magnetic poles P2 and Pl of the magnetic body B1. Therefore, the rotational torque that prevents the rotor R from rotating counterclockwise is not generated in the bipolar permanent magnet M1, but the N pole and the N pole of the bipolar permanent magnet M2 are not opposed to each other. S
Since the poles are not opposed to the magnetic poles P4 and F3 of the magnetic body B2, a rotational torque is generated in the two-pole permanent magnet body M2 that prevents the rotor R from rotating counterclockwise.

Furthermore, if the rotor R does not rotate clockwise from the above-mentioned third rotation position shown in FIGS. 8, 11, and 14, the two-pole permanent Since the N and S poles of the magnet M2 do not face the magnetic poles P4 and F3 of the magnetic body B2, the two-pole permanent magnet M2 prevents the rotor R from rotating clockwise. No rotational torque is generated, but since the N and S poles of the two-pole permanent magnet M1 do not oppose the magnetic poles P2 and Pl of the magnetic body B1, the rotor R is rotated clockwise to the two-pole permanent magnet M1. A rotational torque is generated that prevents the product from rotating.

For the above reasons, when power is not supplied to either of the excitation windings L1 and F2 of the stator S, the rotor R is
rotational position, a second rotational position, a third rotational position, and a fourth rotational position.
One of the rotational positions is taken.

Also, the display surface is as shown above), and the motor mechanism Q
is mounted on the rotor R so that the display surfaces F1, F2, F3 and F4 respectively face forward when in the first, second, third and fourth rotational positions described above. There is.

Therefore, the rotor R of the motor mechanism Q now assumes the above-mentioned first rotational position, and therefore the display element E is in a state in which the display surface F1 of the display surface body is directed forward (this is the first rotational position). 1). Then, from such a state where the display element E is in the first state, as shown in FIG. Supply means J2
Power is supplied for a short time via the power supply means J4, and from a time slightly before or after the start of power supply, a short supply of power is supplied to the excitation winding L2 via the power supply means J4 described above. Even after the supply of time, the display element E maintains the above-mentioned first state.

The reason is as follows.

By supplying power to the excitation winding L1 via the power supply means J2, the magnetic poles P1 and P2 of the magnetic body B1 become S poles and N poles, respectively, so that the two-pole permanent magnet body M1 has a counterclockwise Suppose that a small rotational torque is generated in the direction, and the rotor R cannot rotate counterclockwise. However, by supplying power to the excitation winding 12 via the power supply means J4, the magnetic poles P3 and P/l of the magnetic body B2 become S and N poles, respectively, and therefore the two-pole permanent magnet A small clockwise rotational torque is generated in the body M2, and the rotor R
cannot rotate clockwise. Therefore, no rotational torque is generated in the rotor R, or only a small rotational torque in the counterclockwise or clockwise direction is generated in the rotor R.

When a small rotational torque in the counterclockwise direction is generated in the rotor R, the N and S poles of the bipolar permanent magnet M1 become the S and N poles of the magnetic body B1, respectively.
2, so the two-pole permanent magnet M
1, although no rotational torque is generated to prevent the rotor R from rotating counterclockwise, the N and S poles of the bipolar permanent magnet M2 are connected to the S and N poles of the magnetic body B2, respectively. Since the magnetic poles P3 and P4 are not opposed to each other, a rotational torque is generated in the two-pole permanent magnet M2 that prevents the rotor R from rotating counterclockwise.

In addition, when the above-mentioned small clockwise rotational torque is generated in the rotor R, the N pole and S pole of the two-pole permanent magnet M2
Since the poles do not face the magnetic poles P3 and P4, which are S and N poles, respectively, the two-pole permanent magnet M2 has a rotation force that prevents the rotor R from rotating clockwise. Although no torque is generated, the N and S poles of the bipolar permanent magnet M1 do not face the magnetic poles P1 and P2, which are the S and N poles of the magnetic body B1, respectively, so the bipolar permanent magnet A rotational torque is generated in the body M1 that prevents the rotor R from rotating clockwise.

For the above reasons, even if power is supplied to the excitation windings L1 and L2 via the power supply means J2 and J4, respectively, from the state in which the display element E is in the first state described above,
The display element E maintains the first state described above.

Further, from the state where the display element E is in the first state described above, as shown in FIG. 6, power is supplied to the excitation winding L1 via the power supply means J2 for a short time, Moreover, if power is supplied to the excitation winding L2 for a short time via the power supply means J3 mentioned above from a time slightly before or after the start of supply of power, the rotor R of the motor mechanism Q takes the above-mentioned fourth rotational position, and as a result, the display element E changes to a state in which the display surface F4 is facing forward (this is referred to as the fourth state), keep it.

The reason is as follows.

By supplying power to the excitation winding L1 via the power supply means J2, the magnetic poles P1 and P2 of the magnetic body B1 become the S pole and N14, respectively. In this case, the magnetic pole P1
and the N pole of the bipolar permanent magnet M1 and Sf at one end a of P2.
Since the magnets i are facing each other, no rotational torque is generated in the two-pole permanent magnet M1, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated. In silence,
By supplying power to the excitation winding L2 via the power supply means J3, the magnetic poles P3 and P4 of the magnetic body B2 become N14 and S poles, respectively, and in this case, one end of the magnetic poles P3 and P4 Since the N and S poles of the two-pole permanent magnet M2 are facing each other, the two-pole permanent magnet M2
Due to the repulsive force between the N pole of the bipolar permanent magnet M2 and the N pole of the magnetic pole P3, and the repulsive force between the S pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P4, the bipolar permanent magnet M2 A large rotational torque in the counterclockwise direction is generated. Therefore, a counterclockwise rotational torque is generated in the rotor R, and the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and the rotor R rotates 45 degrees counterclockwise from the above-mentioned first state.
If the rotation exceeds 10°, the N and S poles of the bipolar permanent magnet M1 are opposite to the magnetic poles P1 and P2, which are the S and N poles of the magnetic body B1, respectively. No rotational torque is generated in the permanent magnet M1, or even if it is generated, only a small rotational torque in the clockwise direction is generated. Silently, the Nli and S poles of the bipolar permanent magnet M2 approach the magnetic poles P4 and P3, which are the S and N poles, respectively, so that the N pole of the bipolar permanent magnet M2 and SFi of the magnetic pole P4 are A large rotational torque in the counterclockwise direction is generated in the bipolar permanent magnet M2 due to the attractive force between the S pole of the bipolar permanent magnet M2 and the N pole of the magnetic pole P3. For this reason,
The rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates over 90 degrees counterclockwise from the above-mentioned first rotation position, the bipolar permanent magnet Since the N pole and S pole of M2 are in a relationship opposite to magnetic poles P4 and P3, which are the S pole and N pole of magnetic body B2, respectively, 2
No rotational torque is generated in the polar permanent magnet M2, but even if it is generated, only a small rotational torque in the counterclockwise direction is generated. Silently, the N pole and S pole of the bipolar permanent magnet M1 are the magnetic poles P1 and P, which are the S pole and the N pole, respectively.
Since it is in a relationship that does not face 2, 1.2 pole permanent magnet M1
At this time, a large rotational torque is generated which prevents the rotor R from rotating more than 90' counterclockwise from the first state. Therefore, the rotor R does not rotate beyond 90' in the counterclockwise direction from the first rotation position.

For the above-mentioned reasons, if power is supplied to the excitation windings L1 and L2 via the power supply means J2 and J3, respectively, from the state in which the display cable E is in the first state described above,
The display element E switches to and remains in the fourth state described above.

Further, from the state in which the display element E is in the first state described above, power is supplied to the excitation line L1 for a short time via the power supply means J1, as shown in FIG. ,
Moreover, if power is supplied for a short time to the excitation winding L2 via the power supply means J4 mentioned above from a time slightly before or after the start of the supply amount of power, the rotor R of the motor mechanism Q assumes the second rotational position mentioned above, and thus,
The display element E changes to a state in which the display surface F2 faces forward (this is referred to as a second state), and maintains the second state.

The reason is as follows.

By supplying power to the excitation winding L2 via the power supply means J4, the magnetic poles P3 and P4 of the magnetic body B2 become S and N poles, respectively. In this case, one end of the magnetic poles P3 and P4 Since the N and S poles of the two-pole permanent magnet M2 are facing each other, no rotational torque is generated in the two-pole permanent magnet M2, or even if it is, only a small rotational torque in the clockwise direction is generated. . However, by supplying power to the excitation winding L1 via the power supply means J1, the t;n poles P1 and P2 of the magnetic body B1 become N and S poles, respectively, and in this case, the magnetic pole P1 Since the N and S poles of the bipolar permanent magnet M1 are facing one end a of P2, the repulsive force between the N pole of the bipolar permanent magnet M1 and the N pole of the magnetic pole P1 is Polar permanent magnet M
Due to the repulsive force between the S pole of P1 and the S pole of magnetic pole P2,
A large clockwise rotational torque is generated in the two-pole permanent magnet M1. Therefore, a clockwise rotational torque is generated in the rotor R, and the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 45° clockwise from the above-mentioned first rotational position.
If the rotation exceeds 10°, the N and S poles of the bipolar permanent magnet M2 are opposite to the magnetic poles P3 and P4, which are the S and N poles of the magnetic body B2, respectively. No rotational torque is generated in the permanent magnet M2, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated. However, since the N and S poles of the bipolar permanent magnet M1 approach the magnetic poles P2 and Pl, which are the S and N poles, respectively, the N pole of the bipolar permanent magnet M1 and the S pole of the magnetic pole P2 A large clockwise rotational torque is generated in the bipolar permanent magnet M1 due to the attractive force between the S pole of the bipolar permanent magnet M1 and the N pole of the magnetic pole P1. Therefore, the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and if the rotor R rotates more than 90 degrees clockwise from the above-mentioned first state, the N pole of the bipolar permanent magnet M1 and Since the S pole faces the magnetic poles P2 and Pl, which are the S and N poles of the magnetic body B1, respectively, no rotational torque is generated in the bipolar permanent magnet M1, or even if it is generated, the clock Only a small rotational torque in the direction is generated. Silently, the N and S poles of the bipolar permanent magnet M2 have become S and N poles, respectively! 11'4 P 3 and P
4, so the two-pole permanent, permanent magnet M2
At this time, a large rotational torque is generated which prevents the rotor R from rotating more than 90' clockwise from the first state. Therefore, the rotor R does not rotate beyond 90' clockwise from the first rotation position.

For the above-mentioned reasons, the excitation winding I! When power is supplied to 2L1 and L2 through the power supply means No1 and J4, respectively, the display element E changes to the second state described above,
Keep that second state.

Furthermore, from the state where the display element E is in the first state described above, as shown in FIG. 8, power is supplied to the excitation winding L1 via the power supply means J1 for a short time, Moreover, if power is supplied to the excitation winding L2 for a short time via the power supply means J3 mentioned above from a time slightly before or after the start of supply of power, the rotor R of the motor mechanism Q assumes the third rotational position mentioned above, and thus,
The display element E changes to a state 8 (this is referred to as a third state) in which the display surface F3 faces forward, and maintains the third state.

The reason is as follows.

Power is supplied to the excitation winding L1 through the power supply means J1, and power is supplied to the excitation winding L1 through the power supply means J2 from a time slightly after the time when the power supply starts. shall be taken as a thing.

In such a case, power is supplied to the excitation winding L1 via the power supply means J1, so that the magnetic pole P of the magnetic body B1 is
1 and P2 become N and S poles, respectively, and in this case, a two-pole permanent magnet M1 is attached to one end a of magnets iP1 and P2.
Since the N and S poles of are facing each other, the repulsive force between the N pole of the bipolar permanent magnet M1 and the N pole of the magnetic pole P1,
A large clockwise rotational torque is generated in the two-pole permanent magnet M1 due to the repulsive force between the S pole of the two-pole permanent magnet M1 and the 5ffi of the magnetic pole P2. Therefore, a clockwise rotational torque is generated in the rotor R, and the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and if the rotor R rotates more than 45 degrees clockwise from the above-mentioned first state, the N pole of the two-pole permanent magnet M1 and magnetic poles whose S poles are S and N poles [P2 and P
l, so the N pole of the two-pole permanent magnet M1 and the magnetic pole P2
A large clockwise rotating torque is applied to the bipolar permanent magnet M1 due to the attractive force between the S pole of the bipolar permanent magnet M1 and the N pole of the Ia pole P1. Occur.

Further, the rotor R is configured to supply power to the excitation winding L2 via the X source supply means J3 at the first point described above.
If the point is at or near the point in time when the magnetic body B2 has rotated more than 45 degrees clockwise from the rotation position, from that point on, the magnetic poles P3 and P4 of the magnetic body B2 become the Ni and S poles, respectively, and in this case , since the N and S poles of the bipolar permanent magnet M2 are opposite to the magnetic poles P3 and P4, respectively, the repulsive force between the N pole of the bipolar permanent magnet M2 and the N pole of the magnetic pole P3 is A clockwise rotational torque is generated in the bipolar permanent magnet M2 due to the repulsive force between the S pole of the polar permanent magnet M2 and the S pole of the magnetic pole P4.

Therefore, the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and if the rotor R rotates more than 90'' clockwise from the above-mentioned first state, the S and N poles of the magnetic body B1, respectively. Since the N and S poles of the two-pole permanent magnet M1 face one end of the magnetic poles P2 and Pl, respectively, no rotational torque is generated in the two-pole permanent magnet M1, or even if it is generated, , only a small rotational torque in the clockwise direction is generated.However, the N and S poles of the bipolar permanent magnet M2 are connected to one end a of the magnetic poles P3 and P4, which are the N and S poles, respectively, of the magnetic body B2. Since they face each other, there is a repulsive force between the N pole of the bipolar permanent magnet M2 and the N pole of the magnetic pole P3, and a repulsive force between the S pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P4. As a result, a large clockwise rotational torque is generated in the two-pole permanent magnet M2.Therefore, a clockwise rotational torque is generated in the rotor R, causing the rotor R to rotate clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 13 clockwise from the above-mentioned first rotational position.
If the rotation exceeds 5 degrees, the N and S poles of the bipolar permanent magnet M1 are opposed to the magnetic poles P2 and Pl, which are the S and N poles of the magnetic body B1, respectively. No rotational torque is generated in the polar permanent magnet M1, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated. Silently, the N and S poles of the bipolar permanent magnet M2 approach the magnetic poles P4 and P3, which are the S and N poles, respectively, so the N pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P4 and the S pole of the two-pole permanent magnet M2 and the magnetic pole P3.
Due to the attractive force between the N pole of the bipolar permanent magnet M2
A large clockwise rotational torque is generated. For this reason,
The rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 18 clockwise from the aforementioned first rotational position.
If it rotates beyond 0°, the N and S poles of the bipolar permanent magnet M2 will be in a relationship opposite to the magnetic poles P4 and P3, which are the S and N poles of the magnetic body B2, respectively. No rotational torque is generated in the second permanent magnet M2, or even if it is generated, only a small rotational torque in the clockwise direction is generated.

However, since the N and S poles of the two-pole permanent magnet M1 do not face the magnetic poles P2 and Pl, which are the S and N poles, respectively, the rotor R is connected to the two-pole permanent magnet M1. A large rotational torque is generated that prevents the rotor from rotating more than 180° clockwise from the first state.

Therefore, the rotor R does not rotate more than 180° clockwise from the first rotation position.

In the above description, power is supplied to the excitation winding L1 via the power supply means J1, and then, from a slightly later point in time than the time when the power is supplied, the power supply means J3 is supplied to the excitation winding L2.
, but on the contrary, power is supplied to the excitation winding L2 via the power supply means J3, and then at a point slightly later than the time when the power is supplied. , when power is supplied to the excitation winding L1 via the power supply means J1, detailed explanation is omitted, but the rotor R is moved to the above-mentioned first rotational position in the counterclockwise direction opposite to that described above. Rotate by 180° from

For the above-mentioned reasons, if power is supplied to the excitation windings L1 and L2 via the power supply means J1 and J3, respectively, from the state in which the display element E is in the first state described above,
The display element E changes to the above-mentioned third state, and the third state
maintain the condition. .

Further, the rotor R of the motor mechanism Q takes the above-mentioned fourth rotational position, so that the display element E faces the display surface F4 of the display surface body forward. Assume that the state is as follows. Then, from the state in which the display element E is in the fourth state, as shown in FIG. Power is supplied via means J2 for a short time, and from a time slightly before or after the start of supply of power, power is supplied to excitation winding L2 via power supply means J3 described above. Even if the supply is performed for a short period of time, the display element E maintains the fourth state described above.

The reason is as follows.

By supplying power to the excitation winding L1 via the power supply means, No.2, the magnetic poles P1 and P2 of the magnetic body B1 become S poles and N poles, respectively, so that the two-pole permanent magnet body M1 Assume that a small clockwise rotational torque is generated and the rotor R cannot rotate clockwise. However, by supplying power to the excitation winding L2 via the power supply means J3, the magnetic poles P3 and P4 of the magnetic body B2 become N and S poles, respectively, and therefore, the two-pole permanent magnet body M2
A small rotational torque in the counterclockwise direction is generated, and the rotor R begins to rotate counterclockwise. Therefore, either no rotational torque is generated in the rotor R, or the rotor R has a reaction time of 51
Only a small rotational torque in the direction, direction, or clockwise direction is generated. When a small rotational torque in the clockwise direction is generated in the rotor R, the N and S poles of the two-pole permanent magnet M1 become the S and N poles of the magnetic body B1, respectively.
2, so the two-pole permanent magnet M
1, although no rotational torque is generated to prevent the rotor R from rotating clockwise, the N of the two-pole permanent magnet M2 is
Since the poles and the S poles are not opposed to the magnetic poles P4 and P3, which are the S and N poles of the magnetic body B2, respectively, the rotor R rotates clockwise in the bipolar permanent...stone body M2. A rotational torque is generated that prevents the product from dying. In addition, when the above-mentioned small counterclockwise rotation 1 to 1 torque occurs in the rotor R, the N pole and S pole of the bipolar permanent magnet M2 become the S pole and the N pole, respectively, and the magnetic poles P4 and P3 Since there is no relationship in which they do not face each other, in the two-pole permanent magnet M2,
Although no rotational torque is generated to prevent the rotor R from rotating counterclockwise, the N and S poles of the bipolar permanent magnet M1 become the S and Nff1 of the magnetic body B1, respectively. Since the two-pole permanent magnet M1 does not face the magnets ff1P1 and P2, a rotational torque that prevents the rotor R from rotating counterclockwise is generated in the two-pole permanent magnet M1.

For the above reasons, even if power is supplied to the first winding tlAL1 and L2 of the display element E from the fourth state described above through the power supply means J2 and J3, respectively, the display will not be displayed. Element E maintains the fourth continuous state.

Further, from the state where the display element E is in the fourth state described above, as shown in FIG. 9, the display element E is excited t! Power is supplied to the first winding 1-1 for a short time via the power supply means J2, and from a time slightly before or after the start of the power supply, the excitation is 6N! When power is supplied to the winding L2 for a short period of time via the power supply means J4 described above, the rotor R of the motor mechanism Q assumes the first rotational position described above, so that the display element E , the display cloth F1 is switched to a first state in which it is directed toward iri, and the first state is maintained.

The reason is as follows.

When power is supplied to the excitation winding L1 via the power supply means J2, the magnetic poles P1 and P2 of the magnetic body B1 become S poles and N+ poles, respectively. In this case, one end of the magnetic poles P1 and P2 becomes Since the N and S poles of the bipolar permanent magnet M1 are opposed to each other, no rotational torque is generated in the bipolar permanent magnet M1, or even if it is generated, only a small rotational torque in the clockwise direction is generated. By silently supplying power to the excitation winding L2 via the power supply means J4, the magnetism of the magnetic body B2 increases. 4P3 and P4 become 5ffi and N pole respectively, and in this case the magnetic pole P
3 and one end a of P4 are the S pole and N pole of the two-pole permanent magnet M2.
Since the poles are facing each other, there is a repulsive force between the N pole of the bipolar permanent magnet M2 and the N14 of the magnetic pole P4, and the S pole of the bipolar permanent magnet M2 and the S pole of the vA pole P3. A large clockwise rotational torque is generated in the two-pole permanent magnet M2 due to the repulsive force. Therefore, a clockwise rotational torque is generated in the rotor R, and the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and if the rotor R rotates more than 45 degrees clockwise from the fourth state described above, the NwI and S of the 244i permanent magnet M1 Since the poles are opposite to the magnetic poles P1 and P2, which are the si and N poles of the magnetic body B1, respectively, no rotational torque is generated in the bipolar permanent magnet M1, or even if it is generated, it is only in the counterclockwise direction. Only a small rotational torque is generated. Silently, the N pole of the two-pole permanent magnet M2 approaches the magnets fiP3 and P4, which are the S and N poles, respectively, so the N pole of the two-pole permanent magnet M2 and the S pole of the magnetic pole P3
The attractive force between the pole and the S pole of the bipolar permanent magnet M2! 1
Due to the attractive force between pole P4 and NK, a bipolar permanent magnet,
A large clockwise rotational torque is generated at 5th rest M2. Therefore, the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 90' clockwise from the above-mentioned fourth state.
If the rotation exceeds , the N and S poles of the two-pole permanent magnet
Since the poles are opposed to the magnetic poles P3 and P4, which are the S and N poles of the magnetic body B2, respectively, no rotational torque is generated in the two-pole permanent magnet M2, or even if it is generated, it is rotated clockwise. Only a small rotational torque is generated. However, since the N and S poles of the two-pole permanent magnet M1 do not face the magnetic poles P1 and P2, which are the S and N8 poles, respectively, the rotor R is attached to the two-pole permanent magnet M1.
A large rotational torque is generated that prevents the rotor R from rotating more than 90' clockwise from the fourth state.This causes the rotor R to rotate more than 90' clockwise from the fourth state. It does not rotate.

For the above-mentioned reasons, if power is supplied to the excitation windings L1 and +2 via the power supply means J2 and J4, respectively, from the state in which the display element E is in the fourth state described above, the display element E transforms into the first state described above and remains in that first state.

Furthermore, from the state in which the display element E is in the fourth state described above, as shown in FIG.
Supplying power for a short time via the power supply means J1,
Moreover, if power is supplied to the excitation windings 19 and 12 for a short time via the power supply means J4 mentioned above from a time slightly before or after the start of the power supply, the motor machine! ii The rotor R of Q assumes the above-mentioned second rotational position, so that the display element E changes to the second state in which the display surface F2 is facing forward, and the second state is changed to keep.

The reason is as follows.

Power is supplied to the excitation winding L1 via the power supply means J1, and power is supplied to the excitation winding 12L2 via the power supply means J4 from a time slightly after the start of the supply of power. do.

In such a case, power is supplied to the excitation winding 1 via the power supply means J1, so that the magnetic pole P of the magnetic body B1 is
1 and P2 become the N pole and S pole, respectively, and in this case, one end of the magnetic poles P1 and P2 is connected to the bipolar permanent magnet M1.
Since the N and S poles of are facing each other, the repulsive force between the N pole of the bipolar permanent magnet M1 and the Ni of the magnetic pole P1,
Due to the repulsive force between the S pole of the bipolar permanent magnet M1 and the S pole of the magnetic pole P2, a large rotational torque in the counterclockwise direction is generated in the bipolar permanent magnet M1. Therefore, a counterclockwise rotational torque is generated in the rotor R, and the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates more than 45'' in the counterclockwise direction from the above-mentioned fourth rotation position, the two-pole permanent magnet N of body M1
As the poles and S poles approach magnetic poles P2 and Pl, which are S and N poles, respectively, the attractive force between the N pole of bipolar permanent magnet M1 and the S pole of magnetic pole P2 and the bipolar permanent Magnet M
Due to the attractive force between the S pole of P1 and the N pole of magnetic pole P1,
Bipole permanent...A large counterclockwise rotation of 1-lux is generated in the stone body M1.

In addition, the above-mentioned excitation winding 2 is supplied with power supply means J/I.
If the point in time when power is supplied through is the point in time when the rotor R has rotated more than 45 degrees counterclockwise from the above-mentioned fourth rotational position or in the vicinity thereof, then from that point on, the magnetic The magnetic poles P4 and P3 of the body B2 are N and S poles, respectively, and in this case, the N and S poles of the bipolar permanent magnet M2 are opposite to the magnetic IP4 and P3, respectively, so
The two-pole permanent magnet is A large rotational torque in the counterclockwise direction is generated in the magnet M2.

Therefore, the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and the rotor R rotates 9 clockwise from the above-mentioned fourth rotational position.
If it rotates beyond 0', 2
Since the N and S poles of the polar permanent magnet M1 face each other, no rotational torque is generated in the bipolar permanent magnet M1.
Even if it does occur, only a small rotation (-rook) will occur in the counterclockwise direction. Silently, one end of the magnetic poles P4 and P3, which are the N and S poles, respectively, of the magnetic body B2,
Since the N and S poles of the polar permanent magnet M2 face each other, the repulsive force between the N pole of the bipolar permanent magnet M2 and the N pole of the magnetic pole P4, and the S pole of the bipolar permanent magnet M2 S of magnetic pole P3
Due to the repulsive force between the poles, the two poles are permanent... to the stone body M2,
A large rotational torque in the counterclockwise direction is generated. For this reason,
A large rotational torque in the counterclockwise direction is generated in the rotor R, and the rotor R rotates in the counterclockwise direction.

In this way, the rotor R rotates counterclockwise, and the rotor R rotates 1 clockwise from the above-mentioned fourth rotational position.
If the rotation exceeds 35°, the N pole and SK of the bipolar permanent magnet M1 are opposed to the S pole of the magnetic body B1 and the la poles P2 and Pl, which are N +4, respectively, so the
No rotational torque is generated in the polar permanent magnet M1, or even if it is generated, only a small rotational torque in the clockwise direction is generated. Silently, the N pole and S pole of the binary permanent magnet M2 are the magnetic poles P3 and P4, which are the S pole and the N pole, respectively.
, so due to the attractive force between the N pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P3, and the attractive force between SK of the bipolar permanent magnet M2 and the N pole of the magnetic pole P4, A large rotational torque in the counterclockwise direction is generated in the permanent magnet M2. Therefore, the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates over 180° counterclockwise from the fourth rotation position described above, the bipolar permanent magnet M2 Since the N pole and S+ of the magnetic body B2 are in a relationship opposite to the magnetic poles P3 and P4, which are the S pole and the N pole, respectively, the 2
No rotation torque is generated in the polar permanent magnet M2, or even if it is generated, only a small rotation of 1 to 1 torque in the counterclockwise direction is generated. Without saying a word, Ni and S of the two-pole permanent magnet M1
Magnetic KP2 whose poles are S pole and Nff1, respectively.
and 'P1, so that the 2i permanent magnet M1 has a large rotation that prevents the rotor R from rotating more than 180° counterclockwise from the fourth rotational position. Torque is generated. Therefore, the rotor R does not rotate more than 180 degrees counterclockwise from the fourth rotation position.

In the above description, power is supplied to the excitation winding L1 via the power supply means J1, and then, from a slightly later point in time with respect to the time when the power is supplied, the excitation winding I! The case where power is supplied to JL2 via the power supply means J4 has been described, but conversely, power is supplied to the excitation winding L2 via the power supply means J4, and then, at the time of supplying the power, From a slightly later point on, encouragement! When power is supplied to the first winding L1 via the power supply means J1, detailed explanation will be omitted, but the rotor R is rotated clockwise from the fourth rotational position n to 180 degrees. Rotate by °.

For the above-mentioned reason, if power is supplied to the excitation windings L1 and L2 through the power supply means J1 and J4, respectively, from the state in which the display element E is in the fourth state described above, the display Element E switches to and remains in the second state described above.

Further, from the state where the display element F is in the fourth state described above, as shown in FIG. 11, power is supplied to the excitation winding L1 via the power supply means J1 for a short time, Moreover, if power is supplied to the excitation winding L2 for a short time via the power supply means J3 mentioned above from a time slightly before or after the start of supply of power, the rotor R of the motor mechanism Q assumes the third rotational position mentioned above, and thus,
The display element E switches to a third state in which the display surface F3 faces forward, and maintains the third state.

The reason is as follows.

By supplying power to the 16th excitation volume aL2 via the power supply means J3, the magnetic poles P3 and P4 of the magnetic body 82 are
are the N pole and S pole, respectively, but in this case, the magnetic pole P3
And since the S and N poles of the bipolar permanent magnet M2 are facing one end a of P4, 21! i Permanent magnet M2
No rotational torque is generated, or if it is generated, only a small rotational torque in the counterclockwise direction is generated. By silently supplying power to the excitation winding [1 via the power supply means J1, the magnetic poles P1 and P2 of the magnetic body B1
become the N and S poles, respectively, and in this case, the N and S poles of the bipolar permanent magnet M1 are opposite to one end of the magnetic poles P1 and P2, respectively, so the bipolar permanent magnet M1
The repulsive force between the N pole of P1 and the N pole of magnetic pole P1, and 2! ! Due to the repulsive force between the S pole of the permanent magnet M1 and the S pole of 1aiP2, a large rotational torque in the counterclockwise 31 direction is generated in the bipolar permanent magnet M1. Therefore, a counterclockwise rotational torque is generated in the rotor R, and the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and the rotor R rotates 4 clockwise from the above-mentioned fourth rotational position.
If the rotation exceeds 5 degrees, the N and S poles of the 2Ki permanent magnet M2 are opposite to the magnetic poles P4 and P3, which are the S and N poles of the magnetic body B2, respectively, so the two poles No rotational torque is generated in the permanent magnet M2, or even if it is generated, only a small rotational torque in the clockwise direction is generated. However, since the N and S poles of the bipolar permanent magnet M1 approach the Ia poles P2 and Pl, which are the S and N poles, respectively, the N pole of the bipolar permanent magnet M1 and the S pole of the magnetic pole P2 and the S pole and magnetic pole P of the bipolar permanent magnet M1.
The two-pole permanent magnet M
1, a large rotational torque in the counterclockwise direction is generated. Therefore, the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates over 90 degrees counterclockwise from the fourth rotation position described above, the two-pole permanent magnet NA of M1
and S pole are in a relationship opposite to magnetic poles P2 and Pl, which are the S pole and N pole of magnetic body B1, respectively, so 2
No rotational torque is generated in the polar permanent magnet M1, but even if it is generated, only a small rotational torque in the counterclockwise direction is generated. However, since the Nl and S poles of the two-pole permanent magnet M2 do not face the magnetic poles P4 and P3, which are the S pole and N14, respectively, the two-pole permanent magnet M2
, the rotor R rotates 90° counterclockwise from the fourth rotational position.
A large rotational torque is generated that prevents rotation beyond the limit. Therefore, the rotor R does not rotate beyond 90' in the counterclockwise direction from the fourth rotation position.

For the above-mentioned reason, if power is supplied to the excitation windings L1 and [2 through the power supply means J1 and J3, respectively, from the state in which the display element E is in the fourth state described above,
The display element E changes to the above-mentioned third state, and the third state
maintain the condition.

Further, the rotor R of the motor mechanism Q assumes the second rotational position described above, and therefore the display element E has a second rotation position of the display element E, in which the display surface F2 of the display surface body is directed forward. Assume that the state is as follows. Then, from such a state where the display cable E is in the second state, the motor is connected to the above-mentioned power supply to the excitation winding L1 constituting the stator S of the structure Q, as shown in FIG. Power is supplied for a short time via the supply means J1, and from a time slightly before or after the start of supply of power, the power is supplied to the excitation winding L2 via the power supply means J4 described above. Even if it is supplied for a short period of time, the display element E maintains the above-mentioned second state.

The reason is as follows.

By supplying power to the excitation winding L1 via the power supply means J1, the magnets FMP1 and P2 of the magnetic body B1 become NW and S j&, respectively, so that the two-pole permanent magnet body M1 has a clockwise direction. A small rotational torque is generated, and the rotor R does not rotate clockwise. However, encouragement! By supplying power to the first winding L2 via the power supply means J4, the magnets 14iP3 and P of the magnetic body B2
4 becomes the S pole and N8i, respectively, and therefore a small counterclockwise rotating torque is generated in the two-pole permanent magnet M2, and the rotor R is prevented from rotating counterclockwise. Therefore, either no rotational torque is generated on the rotor R, or the rotor R
In this case, only a small rotational torque in the counterclockwise π1 direction or in the clockwise direction is generated. When a small clockwise rotational torque is generated in the rotor R, the S and N poles of the two-pole permanent magnet M1
Since the poles do not face the magnets ff1P1 and P2, which are the N and S poles of the magnetic body B1, the rotor R cannot rotate clockwise in the two-pole permanent magnet M1. However, the NA and S poles of the two-pole permanent magnet M2 are connected to the magnetic body B2, respectively.
Since the magnetic poles P3 and P4, which are the S and N poles, are not opposed to each other, the rotor R
A rotational torque is generated that prevents the wheel from rotating clockwise. In addition, when the above-mentioned small rotational torque in the counterclockwise direction is generated in the rotor R, the two-pole permanent magnet M2
Since the N pole and SwJ of are not in a relationship where they do not oppose the magnetic poles P3 and P4, which are the S pole and N pole, respectively,
2, the rotational torque that prevents the rotor R from rotating in the counterclockwise direction is not generated in the permanent magnet M2, but the rotational torque of 2
The N pole and S pole of the polar permanent magnet M1 are each magnetic body B1.
Since the magnetic poles P2 and Pl, which are the S and N poles of
A rotational torque is generated that prevents the motor from rotating counterclockwise.

For the above reasons, even if the display element E is in the second state described above, power is supplied to the excited l-1 and L2 via the power supply means J1 and J4, respectively. , display element " maintains the second state described above.

Further, from the state in which the display element E is in the second state mentioned above, as shown in FIG.
Power is supplied via the power supply means J 2 for a short time, and from a time slightly before or after the start of the supply of power, the power supply means J described above is applied to the excitation winding L2.
4, when power is supplied for a short time, the rotor R of the motor mechanism Q assumes the above-mentioned first rotational position, so that the display element E faces the display surface F1 forward. , and maintains that first state.

The reason is as follows.

By supplying power to the excitation winding L2 via the power supply means J4, the magnetic poles P3 and P4 of the magnetic body B2 become S poles and NK, respectively, but in this case, one end a of the magnetic poles P3 and P4 Since the N and S poles of the two-pole permanent magnet M2 are facing each other, no rotational torque is generated in the two-pole permanent magnet M2, or even if it is, only a small rotational torque in the counterclockwise direction is generated. . However, by supplying power to the excitation winding L1 via the power supply means J2, the magnetic poles P1 and P2 of the magnetic body B1 become the S pole and Nll, respectively, and in this case, the magnetic pole P1
Since the S and N poles of the two-pole permanent magnet M1 face each other at one end of P2, the N pole of the two-pole permanent magnet M1 faces each other.
The repulsive force between the pole and the N pole of the magnetic pole P2 and the repulsive force between the S pole of the bipolar permanent magnet M1 and the S pole of the magnetic pole P1 cause the bipolar permanent magnet M1 to move counterclockwise. A large rotational torque is generated. Therefore, a counterclockwise rotational torque is generated in the rotor R, and the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates more than 45 degrees counterclockwise from the above-mentioned second rotation position, the two-pole permanent magnet Since the N and S poles of M2 are opposite to the magnetic poles P3 and P4, which are the S and N poles of the magnetic body B2, respectively, no rotational torque is generated in the bipolar permanent magnet M2, or rotational torque is generated. Even so, only a small rotational torque in the clockwise direction is generated. Silently, the north and south poles of 2ffl permanent l permanent 1 are,
As it approaches the magnetic poles P1 and P2, which are the S pole and N pole, respectively, the N pole of the bipolar permanent magnet M1 and the S pole of the magnetic pole P1
The attractive force between the poles and the S pole of the bipolar permanent magnet M1 and 11
Due to the attractive force between the pole P2 and the N pole, a large rotational torque in the counterclockwise direction is generated in the bipolar permanent magnet M1. Therefore, the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates over 90' counterclockwise from the above-mentioned second rotation position, the two-pole permanent magnet The N pole and S pole of M1 are the S pole and Nl of the magnetic body B1, respectively! Since the relationship is opposite to P1 and P2,
No rotational torque of the bipolar permanent magnet M1 is generated, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated. However, the N and S poles of the bipolar permanent magnet KM2
Since the poles do not face the magnetic poles P3 and P4, which are S and N poles, respectively, the rotor R is rotated 90 degrees counterclockwise from the second rotational position to the 2V71 permanent magnet M2.
A large rotational torque is generated that prevents rotation beyond 20°. Therefore, the rotor R.

Do not rotate more than 90° counterclockwise from the second rotation position.

For the above-mentioned reasons, if power is supplied to the excitation windings 1 and L2 from the state in which the display element E is in the second state described above through the power supply means J2 and J4, respectively, the display Element E switches to the first state described above and remains in that first state.

Furthermore, from the state where the display element E is in the second state mentioned above, as shown in FIG.
Supplying power for a short time via the power supply means J2,
Also, from a time slightly before or after the start of the power supply, the excitation winding 2 is started by the above-mentioned power supply means J3.
If power is supplied for a short time through the motor mechanism Q
The rotor R takes the above-mentioned fourth rotational position, so that the display element E changes to the fourth state in which the display surface F4 faces forward, and maintains the fourth state.

The reason is as follows.

A device that supplies power to the excitation winding L1 via a power supply means J2, and supplies power to the excitation winding L2 via a power supply means J3 from a point slightly after the start of supply of power. shall be.

In such a case, power is supplied to the excitation winding L1 via the power supply means J2, so that the magnetic pole P of the magnetic body B1 is
1 and P2 become the south and north poles, respectively, and in this case, ! Two-pole permanent magnet body M at one end of i-pole P1 and P2
Since the S and N poles of 1 are facing each other, the repulsive force between the N pole of the 2-pole permanent magnet M1 and the N pole of the magnetic pole P2, and the S pole and the N pole of the 2-pole permanent magnet M1 and the magnetic pole P1 A large counterclockwise rotational torque is generated in the two-pole permanent magnet M1 due to the repulsive force between the two-pole permanent magnet M1 and the S pole. Therefore, a counterclockwise rotational torque is generated in the rotor R, and the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and the rotor R rotates 45 degrees counterclockwise from the above-mentioned second state.
If the rotation exceeds 1°, the N and S poles of the bipolar permanent magnet M1 will approach the magnetic poles P1 and P2, which are the S and N poles, respectively, so the Ni of the bipolar permanent magnet M1 will The attractive force between the S pole of the magnetic pole P1 and the S pole of the bipolar permanent magnet M1
Due to the attractive force between the pole and the north pole of rlP2, a large rotational torque in the counterclockwise direction is generated in the bipolar permanent magnet M1.

Further, the above-mentioned point in time when power is supplied to the excitation winding L2 via the power supply means J3 is the point in time when the rotor R has rotated over 45 degrees counterclockwise from the above-mentioned second rotational position. From that point on, the magnetic poles P3 and P4 of the magnetic body B2 become the N pole and 54fi, respectively, and in this case, the magnetic If! Since the N pole and S pole of the bipolar permanent magnet M2 are opposite to P3 and P4, the repulsive force between the N pole of the bipolar permanent magnet M2 and the N pole of NliKP3 and the bipolar permanent magnet S pole of body M2 and magnetic pole P4
A large rotational torque in the counterclockwise direction is generated in the two-pole permanent magnet M2 due to the repulsive force between the S pole and the S pole.

Therefore, the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates over 90'' counterclockwise from the above-mentioned second rotation position, each S of the magnetic body B1 At one end a of the magnetic poles P i and P2, which are the pole and N pole,
Since Nff1 and St of the two-pole permanent magnet M1 face each other, 21'! i Permanent magnet M1 does not generate rotational torque, or even if it does, only a small rotational torque in the counterclockwise direction is generated. Note that the N and S poles of the two-pole permanent magnet M2 are opposite to one end of the magnetic poles P3 and P4, which are N and S poles, respectively, of the magnetic body B2, so the 2(i permanent magnet N pole and magnetic pole P of body M2
Due to the repulsive force between the N pole of P3 and the repulsive force between the S pole of the bipolar permanent magnet M2 and the S+ of the magnetic pole P4, the bipolar permanent magnet M2 undergoes a large counterclockwise rotation. Torque is generated. Therefore, a counterclockwise rotational torque is generated in the rotor R, and the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates more than 135° counterclockwise from the above-mentioned second rotation position, 244! Permanent magnet M1
Since the N and S poles of the magnetic body B1 are opposite to the magnetic poles P1 and P2, which are the S and N poles of the magnetic body B1, the 2
No rotational torque is generated in the polar permanent magnet M1, or even if it is generated, only a small rotational torque in the clockwise direction is generated. However, since the N and S poles of the two-pole permanent magnet M2 approach the magnetic poles P4 and P3, which are the S pole and N+4, respectively, the N and P poles of the two-pole permanent magnet M2 approach.
4 and the attractive force between the S pole of the bipolar permanent magnet M2 and the Nli of the magnetic pole P3, the bipolar permanent magnet M2 is rotated 1 herk in the counterclockwise direction. occurs. Therefore, the rotor R rotates counterclockwise.

In this way, if the rotor R rotates in the counterclockwise direction, and if the rotor R rotates over 180° counterclockwise from the above-mentioned second rotation position, the bipolar permanent Magnet M
Since the N and S poles of 2 are opposite to S[i of magnetic body B2 and tfi K P 4 and P3, which are N poles, respectively, rotational torque is generated in permanent magnet M2 of 2I(i). If it does occur, it will only generate a small counterclockwise rotation.However, 2Vi
The N pole and S pole of the 1 permanent magnet M1 are the S pole and N J4, respectively. Since the relationship is such that they do not face Pl and P2, the rotor R is connected to the 2 pole permanent magnet M1. A large rotational torque is generated that prevents rotation beyond 180° counterclockwise from the state. Therefore, the rotor R moves 180 degrees counterclockwise from the second rotational position.
Do not rotate beyond °.

In the above description, power is supplied to the excitation winding L1 via the power supply means J2, and then, from a slightly later point in time than the time when the power is supplied, the power supply means J3 is supplied to the excitation winding L2.
, but on the contrary, power is supplied to the excitation winding L2 via the power supply means J3, and then at a point slightly later than the time when the power is supplied. , l1iI] When power is supplied to the magnetic winding L1 via the power supply means J2, details! II. Although the explanation will be omitted, the rotor R rotates by 180 degrees from the first rotation position in the clockwise direction opposite to that described above.

For the above-mentioned reasons, if the display element E is in the above-described second state, if power is supplied to the excitation windings 1 and L2 via the power supply means J2 and J3, respectively, The display element E maintains the fourth state described above.

Further, from the state where the display element E is in the second state described above, as shown in FIG. 14, power is supplied to the excitation winding L1 via the power supply means J1 for a short time, In addition, if power is supplied to the excitation winding U2 for a short time via the power supply means J3 mentioned above from a time slightly before or after the start of power supply, the rotor R of the morph mechanism Q can be assumes the third rotational position mentioned above, and thus,
The display element E switches to a third state in which the display surface F3 faces forward, and maintains the third state.

The reason is as follows.

By supplying power to the excitation 1nWIL1 via the power supply means J1, the magnets 14P1 and P of the magnetic body B1
2 are the N and S poles, respectively, but in this case, the magnetic 1f
Since the S and N poles of the bipolar permanent magnet M1 face each other at one end of iP1 and P2, the bipolar permanent magnet M1
1, no rotational torque is generated, or even if it is generated, only a small rotational torque in the clockwise direction is generated. However, by supplying power to the excitation winding 11L2 via the power supply means J3, the magnetic poles P3 and P of the magnetic body B2
4 become north pole and south pole respectively, and in this case,
Since the N and S poles of the two-pole permanent magnet M2 are facing one end a of the magnetic poles P3 and P4, respectively, the repulsive force between Nff1 of the two-pole permanent magnet M2 and Nil of l +i P3 is , 21 has the S pole of the permanent magnet M2 and (,!i pole P4
Due to the repulsive force between the S pole and the S pole, 2vj! A large rotational torque in the clockwise direction is generated during the permanent stone rest M2.

Therefore, a clockwise rotational torque is generated in the rotor R.
The rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 45° clockwise from the above-mentioned second rotational position.
If the rotation exceeds 10°, the N and S poles of the bipolar permanent magnet M1 are opposed to the magnetic poles P2 and Pl, which are the S and N poles of the magnetic body B1, respectively. No rotational torque is generated in the permanent magnet M1, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated. However, since the N and S poles of the bipolar permanent magnet M2 approach the magnetic poles P4 and P3, which are S and Ni, respectively, a , the S pole of the two-pole permanent magnet M2 and 1af
Due to the attractive force between flP3 and the north pole, a large clockwise rotational torque is generated in the bipolar permanent magnet M2. Therefore, the rotor R rotates clockwise.

In this way, the rotor R rotates in the direction of h[, and the rotor R rotates clockwise from the above-mentioned second rotational position to 9
If the rotation exceeds 0°, the N and S poles of the bipolar permanent magnet M2 become the S and N poles of the magnetic body B2, respectively! Since it will be in a relationship opposite to ip4 and P3,
No rotational torque is generated in the two-pole permanent magnet M2, or even if it is generated, only a small rotational torque in the time i1 direction is generated. A magnetic pole P2 in which the NN and S poles of the two-pole permanent magnet body ~41 are Swl and Ni, respectively.
and Pl, a large rotational torque is generated in the two-pole permanent magnet M1 that prevents the rotor R from rotating more than 90 degrees clockwise from the second state. Therefore, the rotor R does not rotate clockwise beyond 90 degrees from the second rotation position.

For the above-mentioned reason, the display element E is changed from the above-mentioned second state to the excitation windings L1 and L2, respectively, by the power supply means J1.
When power is supplied through J3 and J3, the display element E becomes
Converts to the third state described above and maintains the third state.

Further, the rotor R of the motor mechanism Q assumes the third rotational position described above, and therefore the display element E assumes a third state in which the display surface F3 of the display surface body faces forward. It is assumed that there is Then, such a display element E becomes the third
As shown in FIG. 8, from the state of The power is supplied for a certain period of time, and from a point slightly before or after the start of the power supply, the excitation Ii! Even if power is supplied to the first winding L2 through the power supply means J3 described above for a short time, the display element E maintains the third state described above.

The reason is as follows.

By supplying power to the excitation winding L1 via the power supply means J1, the magnetic poles P1 and P2 of the magnetic body B1 become N and S poles, respectively, and therefore the two-pole permanent magnet M1 has a counterclockwise polarity. Suppose that a small rotational torque is generated in the direction, and the rotor R cannot rotate counterclockwise. However, by supplying power to the excitation winding L2 via the power supply means J3, the magnetic poles P3 and P4 of the magnetic body B2 become N poles and S poles, respectively, so that the two-pole permanent magnet body M
2, a small clockwise rotational torque is generated, and the rotor R is unable to rotate clockwise. Therefore, no rotational torque is generated in the rotor R, or only a small rotational torque in the counterclockwise or clockwise direction is generated in the rotor R. When a small rotational torque in the clockwise direction is generated in the rotor R, the Nt and S poles of the two-pole permanent magnet M2 do not face the magnetic poles P4 and P3, which are the S and N poles of the magnetic body B2, respectively. Since there is no relationship between Since it will not face the magnetic poles P2 and Pl, which are the S and N poles of the magnetic body B1, respectively, 2
A rotational torque that prevents the rotor R from rotating clockwise is generated in the polar permanent magnet M1. In addition, when the above-mentioned small rotational torque in the counterclockwise direction is generated in the rotor R, the N and S poles of the two-pole permanent magnet M1 face InIP2 and Pl, which are S+ and N pole, respectively. Since there is no relationship between
Although no rotational torque is generated that prevents the rotor R from fully rotating counterclockwise, the NW of the bipolar water magnet M2
Since the A and S poles do not face the magnetic poles P4 and P3, which are the S and N poles of the magnetic body B2, respectively, the rotor R rotates counterclockwise to the permanent magnet M2. A rotational torque is generated that prevents the product from dying.

For the above reasons, even if power is supplied to the lines L1 and L2 from the display element E in the third state described above through the power supply means J1 and J3, respectively, Display element E maintains the third state.

Furthermore, from the state where the display element E is in the third state mentioned above, as shown in FIG. 15, the excitation winding is changed to 1.
Supplying power for a short time via the power supply means J2,
Also, there is a slight increase in +irf compared to the beginning of the power supply amount.
1*, if power is supplied to the excitation line L2 for a short time via the power supply means J4 described above, the rotor R of the motor Ia IM Q will assume the first rotational position described above. , Therefore, the display element E switches to the first state in which the display surface F1 faces forward, and maintains the first state.

The reason is as follows.

Power is supplied to the excitation winding L1 via the power supply means J2, and power is supplied to the excitation winding L2 through the power supply means No. 4 from a time slightly after the time when the power supply starts. It shall be.

In such a case, power is supplied to the excitation winding L1 via the power supply means J2, so that the magnetic pole P of the magnetic body B1 is
1 and P2 become the S pole and N1 (i, respectively, and in this case, the S pole and N pole of the bipolar permanent magnet M1 are opposite to one end a of the magnetic poles P1 and P2, respectively, so the bipolar permanent magnet Due to the repulsive force between the N pole of body M1 and the N pole of magnetic pole P2, and the repulsive force between the S pole of bipolar permanent magnet body M1 and the S pole of magnetic pole P1, , a large clockwise rotational torque is generated.Therefore, a clockwise rotational torque is generated in the rotor R, causing the rotor R to rotate clockwise.

In this way, the rotor R rotates clockwise, and if the rotor R rotates more than 45 degrees in the training direction from the third rotation position described above, the two-pole permanent magnet A magnetic pole P in which the N and S poles of the body M1 are S and Ni, respectively.
1 and P2, the attractive force between the N pole of the two-pole permanent magnet M1 and the S pole of the magnetic pole P1 and the two-pole permanent magnet M1
Due to the attractive force between the S pole of P2 and the N pole of magnetic pole P2, 2
A large clockwise rotational torque is generated in the polar permanent magnet M1.

Further, the above-mentioned point in time when power is supplied to the excitation winding L2 via the power supply means J4 is the point in time when the rotor R has rotated more than 45° clockwise from the above-mentioned third rotational position, or If it is a point in the vicinity, from that point on, magnetic material B
The magnetic poles P3 and P4 of 2 become S (~ and N 14, respectively, and in this case, the S pole and Nff1 of the 2-pole permanent magnet body M2 are opposite to the magnetic poles P3 and P4, respectively, so the 2-pole permanent magnet body The repulsive force between the N pole of M2 and the N pole of magnetic pole P4, S+ of bipolar permanent magnet M2 and magnetic t4 P
The two-pole permanent magnet M
2, a clockwise rotation of 1-lux is generated.

Therefore, the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and if the rotor R rotates beyond 90' in the o'clock direction from the third rotation position described above, each S of the magnetic body B1 Since the NVp and S poles of the two-pole permanent magnet M1 face one end of vjltiPl and P2, which are the pole and N pole, respectively, no rotational torque is generated in the two-pole permanent magnet M1, or if it is generated. Also, a small clockwise rotation i-
Only lux is generated. However, since the N pole and 814 of the bipolar permanent magnet M2 are opposite to one end a of the magnetic poles P4 and P3, which are the Ni and S poles of the magnetic body B2, respectively, the polarity of the bipolar permanent magnet M2 is Due to the repulsive force between N [ and the N pole of the magnetic pole P4, and the repulsive force between the S pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P3, the bipolar permanent magnet M2 is rotated clockwise. A large rotational torque is generated. Therefore, a clockwise rotational torque is generated in the rotor R, and the rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 13 clockwise from the above-mentioned third rotational position.
If the rotation exceeds 5 degrees, the N and S poles of the bipolar permanent magnet M1 are opposite to the S and N poles of the magnetic body B1, respectively, so the bipolar No rotational torque is generated in the permanent magnet M1, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated.

Silently, the N and S poles of the bipolar permanent magnet M2 approach the magnetic poles P3 and P4, which are the S and N poles, respectively, so that the N pole of the bipolar permanent magnet M2 and the 84 of the magnetic pole P3
(A large clockwise rotational torque is generated in the bipolar permanent magnet M2 by the attractive force between the S+ of the bipolar permanent magnet M2 and the N pole of the magnet 14P4. Therefore, the rotor R rotates clockwise.

In this way, the rotor R rotates in the hour H1 direction, and if the rotor R rotates more than 180° clockwise from the third rotation position described above, the bipolar permanent magnet M2 N of
The pole and the S pole are the S pole and N14i of the magnetic body B2, respectively.
Since the magnetic poles P3 and P4 are opposed to each other, no rotational torque is generated in the two-pole permanent magnet M2.
Even if it does occur, only a small rotational torque in the clockwise direction is generated. However, since the N% and S poles of the bipolar permanent magnet M1 do not face the magnetic poles P1 and P2, which are the S and N poles, respectively, the bipolar permanent magnet M1
1, the rotor R rotates 180 degrees clockwise from the third rotational position.
A large rotational torque is generated that prevents the device from rotating beyond 20°. Therefore, the rotor R does not rotate by more than 180° in the δ1 direction from the third state.

In the above description, power is supplied to the excitation winding L1 via the power supply means J2, and then, from a slightly later point in time than the time when the power is supplied, the power supply means J4 is supplied to the excitation winding L2.
However, on the contrary, power is supplied to the excitation winding L2 via the power supply means J4, and then at a point slightly later than the time when the power is supplied. When power is supplied to the excitation line 14i and the W line 1 through the power supply means J2, detailed explanation will be omitted. Rotate 180° from state 3.

For the above-mentioned reason, the display element E is changed from the above-mentioned third state to the excitation windings L1 and L2 by the power supply means J2.
When power is supplied through J4 and J4, the display element E becomes
Top 311 = maintain the first state.

Further, from the state in which the display element E is in the third state described above, power is supplied to the excitation winding Ml-1 for a short time via the power supply means J2, as shown in FIG. However, if power is supplied to the excitation winding L2 for a short time via the power supply means J3 mentioned above from a time slightly before or after the time when the power supply starts, the motor mechanism Q can be The rotor R takes the above-mentioned fourth rotational position, so that the display element E changes to the fourth state in which the display surface F4 is facing forward, and maintains the fourth state.

The reason is as follows.

By supplying power to the excitation winding L2 via the power supply means J3, the magnetic poles P3 and P4 of the magnetic body B2 become N and S poles, respectively. In this case, one of the magnetic poles P3 and P4 becomes an N pole and an S pole, respectively. Since the S and N poles of the two-pole permanent magnet M2 face 6H5, the 21Ii permanent magnet M2
1 rotational herk does not occur, or even if it does, only a small rotational torque in the clockwise direction is generated. By silently supplying power to the excitation winding L1 via the power supply means J2, the magnetic poles P1 and P2 of the magnetic body B1
become S and N poles, respectively, and in this case, the S and N poles of the bipolar permanent magnet M1 are opposite to the ends a of the magnetic poles P1 and P2, respectively, so the bipolar permanent magnet M1
Due to the repulsive force between the N pole of the magnetic pole P2 and the N pole of the magnetic pole P2, and the repulsive force between the S pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P1, a clock is generated in the bipolar permanent magnet M1. A large rotational torque in the direction is generated.

Therefore, a clockwise rotational torque is generated in the rotor R.
The rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 45° clockwise from the above-mentioned third rotational position.
If the rotation exceeds 100°, the N and S poles of the two-pole permanent magnet M2 are opposed to the Ia poles P4 and P3, which are the S and N poles of the magnetic body 'B2, respectively. No rotational torque is generated in the two-pole permanent magnet M2, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated.

Silently, the N14 and S poles of the bipolar permanent magnet M1 approach IIPl and P2, which are the S pole and Nt(i, respectively, so the N and P1 poles of the bipolar permanent magnet M1 approach A large clockwise rotational torque is generated in the bipolar permanent magnet M1 due to the attractive force between S+Wh and the attractive force between the S pole of the bipolar permanent magnet M1 and the N pole of the magnetic pole P2. Therefore, the first rotor R rotates clockwise.

In this way, the rotor R rotates clockwise, and the rotor R rotates 90 degrees clockwise from the third rotational position mentioned above.
If the rotation exceeds 2°, the N and S poles of the bipolar permanent magnet M1 will be in a relationship opposite to the magnetic poles P1 and P2, which are the S and N poles of the magnetic body B1, respectively. No rotational torque is generated in the extremely permanent stone rest M1, or even if it is generated, only a small rotational torque in the clockwise direction is generated.

Silently, the Nff1 and S poles of the two-pole permanent magnet M2 are the magnetic poles P4 and P3, which are the S pole and the N pole, respectively.
Since the relationship is such that they do not face each other, the two-pole permanent magnet M2,
A large rotational torque is generated that prevents the rotor R from rotating beyond 90' clockwise from the third rotational position. Therefore, the rotor R does not rotate beyond 90 degrees in one direction from the third rotation position.

For the above-mentioned reason, the display element E is changed from the above-mentioned third state to the excitation windings L1 and L2 by the power supply means J2.
When power is supplied through J3 and J3, the display element E changes to the above-mentioned fourth state and maintains the fourth state.

Further, from the state where the display element E is in the third state described above, as shown in FIG. 17, power is supplied to the excitation winding L1 via the power supply means J1 for a short time, Also, from a point slightly before the start of the power supply, the above-mentioned power supply means J4 is applied to the excitation winding L2.
If power is supplied for a short time through the motor mechanism Q
The rotor R assumes the above-mentioned second rotational position, so that the display element E changes to the second state in which the display surface F2 faces forward and maintains the second state.

The reason is as follows.

By supplying power to the excitation winding L1 via the power supply means J1, the magnets ff1P1 and P of the magnetic body B1
2 are the N pole and Sl, respectively, but in this case, the magnetic pole P
1 and P2 -@a to the S and N poles of the bipolar permanent magnet M1
Since the poles are opposed to each other, no rotational torque is generated in the two-pole permanent magnet M1, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated. However,
By supplying power to the excitation vA winding L2 via the power supply means J4, the [6ffl P
3 and P4 become the S pole and N pole, respectively, and in this case, one end of the magnetic poles P3 and P4 is the bipolar permanent magnet M2.
Since the S and N poles of are facing each other, the repulsive force between the N pole of the bipolar permanent magnet M2 and the N pole of the magnetic pole P4,
Due to the repulsive force between the S pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P3, 2tf! A large rotational torque in the counterclockwise direction is generated in the permanent magnetic permanent gap 2. For this reason, the rotor R
A counterclockwise rotational torque is generated, and the rotor R rotates counterclockwise.

In this way, the rotor R rotates counterclockwise, and if the rotor R rotates more than 45 degrees counterclockwise from the third rotation position described above, the two-pole permanent magnet N pole of M1 and slf! are opposed to the magnets P2 and Pl, which are the S and N poles of the magnetic body B1, respectively, so no rotational torque is generated in the bipolar permanent magnet M1, or even if it is generated, it is only in the clockwise direction. Only a small rotational torque is generated. Silently, the N and S poles of the two-pole permanent magnet M2 are
Since it approaches the magnetic poles P3 and P4, which are the S pole and N pole, respectively, the N pole of the bipolar permanent magnet M2 and the S pole of the magnetic pole P3
A large rotational torque in the counterclockwise direction is generated in the two-pole permanent magnet M2 due to the attractive force between the poles and the attractive force between the S pole of the 2VI permanent body M2 and the N pole of the magnetic pole P4. Therefore, the rotor R rotates clockwise.

In this way, the rotor R rotates counterclockwise, and the rotor R rotates 9 clockwise from the above-mentioned third rotational position.
If the rotation exceeds 0°, the N and S poles of the 2*permanent magnet M2 become the S and N poles of the magnetic body B2, respectively! Since the relationship is opposite to poles P3 and P4, 2
No rotational torque is generated in the polar permanent magnet M2, or even if it is generated, only a small rotational torque in the counterclockwise direction is generated. However, the N of the bipolar permanent magnet M1? Since the i and S poles do not face the magnetic poles P2 and Pl, which are the S and N poles, respectively, the two-pole permanent magnet M
1, the rotor R rotates 90 degrees counterclockwise from the third rotational position.
A large rotational torque is generated that prevents rotation beyond .degree. Therefore, the rotor R does not rotate beyond 90' in the counterclockwise direction from the third rotation position.

For the above-mentioned reason, the display element E is changed from the above-mentioned third state to the excitation windings 1-1 and F2 by the power supply means J.
1 and J4, the display element F changes to the above-mentioned second state and maintains the second state.

From the above description, an example configuration of a display device using a rotating display element according to the present invention has become clear.

According to such a configuration of the present invention, -FAs is clear from the above, (i>The excitation winding L1 of the stator S of the motor mechanism Q constituting the display element E is connected to the drive device G.

Power is supplied, and power is supplied to the excitation winding L2 via the power supply means J3 constituting the drive device G from a time slightly before or after the time when the power is supplied. , < iii) Power is supplied to the excitation winding L1 via the power supply means J1, and from a time slightly before or after the time when the power is supplied, power is supplied to the excitation winding L1 via the power supply means J4. (1v) to the excitation winding L1 via the power supply means J1,
With the simple operation of supplying power and selecting to supply power to the excitation windings 1i1L2 via the power supply stage J3 from a time slightly before or after the time of supplying the power, , the display surface F1. of the display surface body constituting the display element E. F4. One of F2 and F3 can be selected to face forward.

Moreover, in this way, the display surface F1°F2. F3
When one of F4 and F4 is selected and facing forward, the excitation winding of the stator S of the motor fiiQ is turned off even if the power supply to F1 and F2 is cut off. The N and S poles of the two-pole permanent magnets M1 and M2 of the rotor R that make up the motor mechanism Q are connected to the m poles P1 and F2 of the magnetic body B1 of the stator S that makes up the motor mechanism Q, and the stator Since it acts on the magnets ff1P3 and F4 of the magnetic body B2 of S, the display surfaces Fl, F2 . One of F3 and F4 is selected,
There is virtually no misalignment in the forward facing state. Moreover, for this reason, it has the characteristic that it does not involve power consumption.

Furthermore, since the display element E has a motor mechanism Q for rotating the display surface, which is built into the display surface, the rotation mechanism for rotating the display surface is
It has a feature that it does not need to be prepared separately from the display element E.

Furthermore, the display surface Fl of the display surface body of the display element F,
F2. The means for selecting one of F3 and F4 is the excitation winding L1 of the stator S constituting the motor 1 structure Q.
Since it is composed of power supply means J1 and J2 for the stator S, and power supply means J3 and J/l for the excitation winding L2 of the stator S, the power supply means is extremely ff? l Favor features that are easy.

Further, the two-pole permanent magnets M1 and M2 of the rotor R constituting the motor mechanism Q have a narrow rectangular cross section perpendicular to the rotating shaft 11, and are arranged at 1.
Ni is placed on both free end faces maintaining an angular spacing of 80°.
Since the structure is a rod-like or plate-like body in which the bipolar permanent magnets M1 and M2 are arranged, the effective angular range around the rotation @11 of the N and S poles of the bipolar permanent magnets M1 and M2 is The shape of the magnets M1 and M2 as rod-like or plate-like objects effectively limits the operation of selecting a desired one of the display surfaces F1, 2, F3 and F4 of the display element E. The present invention is characterized in that it is possible to quickly and smoothly perform the process, and also to effectively eliminate displacement of the selected display surface.

Note that the above description merely shows an example of a display device using a rotary display element according to the present invention, and various modifications and variations are possible.
Changes have been made.

For example, instead of making the two-pole permanent magnets M1 and M2 of the rotor R that constitute the motor mechanism Q separate, they can be constructed as if they were made up of one two-pole permanent magnet, although detailed explanation will be omitted. , and the parts divided in the axial direction are assumed to be bipolar permanent magnet bodies M1 and M2, respectively (however, in this case, α° mentioned above is Oo). Even with such a configuration, although detailed explanation will be omitted, it is possible to obtain the same effects as described above.

Furthermore, in the above description, the rod-shaped or plate-shaped bodies that constitute the two-pole permanent magnet bodies M1 and M2 and that limit the effective angle range of the Ni and S poles are narrow rectangular in cross section, and Although it has been mentioned that the width is less than 45° when viewed from the angle around the rotational axis 11, the width is a relatively small value within the angular range of 45° when viewed from the angle around the rotational axis 11. However, any value may be used as long as it is not 45° swirly.

Further, in the above description, a case has been described in which the rotor R is of a so-called inner rotor type, but it is clear that it can also be configured as an outer rotor type.

Various other modifications and changes may be made without departing from the spirit of the invention.

Note that the display device according to the present invention uses a large number of display elements, and if a panel is manufactured in which a large number of display elements are arranged in a matrix on a common plane or curved surface, the driving device of the large number of display devices can Since a plurality of display surfaces of a large number of display elements can be selectively directed to the screen, characters, symbols, figures, patterns, etc. can be displayed on the panel. Therefore, it can be used, for example, in advertising panels, traffic signs, etc.
