Description

DETAILED DESCRIPTION OF THE INVENTION The present invention displays a wide variety of characters, pictures, etc. by arranging a plurality of display bodies in a matrix as shown in FIG. 1, and driving each display body to rotate. The present invention relates to a display device configured as described above.

First, a conventional display device will be explained.

FIGS. 2 and 3 show a display which is a component of the apparatus shown in FIG. 1, and is a four-sided display.

This display body is a display body 103 made of a square cylinder supported rotatably on a frame 101 via a bearing 102.
, a rotor 104 made of a permanent magnet coupled inside the display body 103, one magnetic pole supported at one end of the frame 101 around the bearing 102 so as to be parallel to the axial direction of the display body 103; It is composed of four electromagnets 105, 106, 107, and 108 with the other magnetic pole facing the rotor 104.

In the above configuration, it is assumed that the display body 103 is in the state shown by the solid line in FIG. 3, for example.

Here, by energizing the coil 109, the electromagnet 106
When an N pole is generated in the electromagnet 108, an S pole is generated in the electromagnet 108. Therefore, the rotor 104 made of a permanent magnet rotates in the direction of the arrow 111, and the S pole of the rotor 104 made of a permanent magnet is aligned with the electromagnet 106 by the broken line. Stop at the opposite position as shown,
Change the square cylinder display surface.

However, for example, if the display body 103 generates an N pole in the electromagnet 107 in the state shown by the solid line in FIG.
An S pole is generated at 05, but these electromagnets 105, 107
Since the rotational force acts in the direction of the arrow 110 (rotation axis direction), the display 103 does not rotate.

Therefore, in order to rotate the N pole of the electromagnet 107 and the S pole of the permanent magnet 104 so that they face each other, first energize the electromagnet 106 or 108 to generate an N pole, and then energize the N pole of the electromagnet 107. to exert a force in the direction of rotation, which causes the N pole of the electromagnet 107 and the S pole of the permanent magnet 104 to
Opposite poles.

However, in the conventional display device described above, when it is desired to display from one display color to the next display color, the electrical configuration is complicated because first the adjacent electromagnet is energized and then the electromagnet to be displayed is energized.

Furthermore, even when it is desired to display the same display color, the display rotates for the above-mentioned reason, making it very difficult to see in a display device in which a large number of display bodies are arranged in a matrix.

In addition, since four electromagnets each having a coil wound thereon are arranged between the display body and the frame, it is not possible to use a display body whose radius is smaller than the radius from the center of the display body to the outer surface of the coil. In a display device arranged in a matrix, it has been impossible to make the display elements smaller and increase the number of display elements in order to make characters, pictures, etc. easier to see.

Furthermore, since the display body cannot be made small, it is not possible to obtain a display device that is compact overall.

Furthermore, since there is an electromagnet with a coil wound between the display body and the frame, an extra space is taken up by the height x of the electromagnet, making the entire display element larger.

Furthermore, there were other drawbacks such as large hunting when the display body stopped.

The present invention eliminates the above-mentioned drawbacks of the conventional technology.In order to display a desired display color, it is necessary to energize only the electromagnet that is desired to be displayed, and the display body is miniaturized to achieve compactness and display effects. The aim is to obtain an extremely large display device.

An example of this will be described below with reference to FIGS. 4 to 11.

4 to 6 show the configuration of a four-sided display according to an embodiment of the present invention.

In the figure, 1 is a main rotating body, which is rotatably attached to an iron core/frame 3 about a rotating shaft 2 as indicated by an arrow A.

4 is a permanent magnet attached, for example, inside the main rotating body 1, and has an N pole at one end of the main rotating body 1, and an S pole at approximately the center.
It has a breaking pole so that it has a pole.

5 and 6 are reversing plates, for example, as shown in FIG.
It is attached to the main rotating body 1 so that it can be rotated in the direction of the arrow B about a rotating shaft 7 that is perpendicular to the direction of the arrow B and located at the center of the main rotating body 1.

Further, the reversing plates 5 and 6 are formed to have half the size of the main rotating body 1, and are normally in contact with the respective display surfaces 8 and 9 of the main rotating body 1.

Both surfaces of the main rotating body 1 and the reversing plates 5 and 6 are coated with a display color.

10 is a white surface coated on one half of the display surface 8 of the main rotating body 1 bordering on the rotation axis 7 and on one surface of the reversing plate 5;
1 is a red surface coated on the other half of the main rotor display surface 8 and the other surface of the reversing plate 5; 12 is a half surface of the main rotor display surface 9 bounded by the rotation axis 7 and one surface of the reversing plate 6; 13 is a yellow surface coated on the other half of the main rotating body display surface 9 and a blue surface coated on the other surface of the reversing plate 6.

Reference numerals 14 and 15 denote permanent magnets attached, for example, inside the reversing plates 5 and 6, respectively, and are provided with magnetic poles, for example, with the free end side as the N pole and the rotating shaft side as the S pole.

Reference numeral 16 denotes a first electromagnet, which is composed of an electrode 17 and a coil portion 18 located opposite to the rotation locus of the permanent magnet 4, and serves as a driving source for rotating the main rotating body 1.

19 is a second electromagnet, and permanent magnets 14 and 1 of reversing plates 5 and 6
Electrode 3 that also serves as a frame at a position facing the rotation locus of 5
and a coil portion 20, and serves as a driving source for reversing the reversing plates 5 and 6.

The rotation angle of the main rotating body 1 is restricted to 180° by a stopper 21 fixed to the main rotating body 1 and a stopper piece 22 integrally formed with the frame 3.

Next, its operation will be explained.

For example, a case where it is desired to display the white surface 10 from the states shown in FIGS. 4 to 6 will be described.

In the states shown in FIGS. 4 to 6, the yellow surface 12 is displayed.

1 Here, the electromagnet 16 is energized, and the seventh
When N and S poles are generated with the polarity shown in the figure, the N pole at the tip of the iron core 17 and the N pole of the permanent magnet 4 of the main rotating body 1 repel each other.
Since the S pole at the tip of the iron core 17 and the N pole of the permanent magnet 4 are attracted, the main rotating body 1 rotates as shown by the arrow A, and the iron core 17
The stopper 21 comes into contact with the stopper piece 22 at a position where the S pole at the tip of the permanent magnet 4 faces the N pole of the permanent magnet 4, and the main rotating body 1 stops.

In this state, the red surface 11 is displayed. Next, when the electromagnet 19 is energized to generate the and<N, S poles shown in FIG. The N pole of is repelled, and the iron core 3
Since the S pole at the tip of the iron core 3 and the N pole of the permanent magnets 14 and 15 are attracted to each other, the reversing plates 5 and 6 rotate as shown by the arrow B, and the iron core 3
Since the reversing plates 5 and 6 come into contact with the display surfaces 8 and 9 of the main rotor 1 and stop at the position where the S pole of the tip of the magnet 14 and the N pole of the permanent magnet 14 and 15 face each other, the reversing plates 5 and 6 stop as shown in FIG. A white surface 10 can be displayed.

Next, if you want to display the red surface 11, energize the electromagnet 16 and generate N and S poles at the tip of the iron core 17 as shown in Figure 7.The S pole at the tip of the iron core 17 and the N pole of the permanent magnet 4 will attract each other. However, since the stopper 21 is stopped at the position where it abuts against the stopper piece 22, the main rotating body 1 does not rotate.

Next, when the electromagnet 19 is energized to generate N and S poles at the tip of the iron core 3 as shown in FIG. 9, the N pole at the tip of the iron core 3 and the N poles of the permanent magnets 14 and 15 repel, Since the three poles and the N poles of the permanent magnets 14 and 15 are attracted, the reversing plates 5 and 6 rotate as shown by the arrow B, so that the S pole at the tip of the iron core 3 and the N pole of the permanent magnets 14 and 15 face each other. At the position, the reversal plate 5, 6
Since it comes into contact with the display surfaces 8 and 9 of the main rotating body 1 and stops, a red surface 11 can be displayed as shown in FIG.

If you want to change to another display color in the same way, use the electromagnet 16,
By changing the magnetic poles of the 19 electrodes, other display colors can be displayed.

Note that even if the electromagnets 16 and 19 are powered off after displaying the display color, the main rotating body 1 is held by the magnetic attraction between the permanent magnets 4 and the iron core 17, and the magnetic attraction between the permanent magnets 14 and 15 and the iron core 3 continues. Since the reversing plates 5 and 6 are held by the inverter, the display color can be maintained, resulting in a power saving effect.

With the above configuration, the interval P' between the four color displays is narrower than the interval P between the display bodies in the conventional square cylinder display shown in FIG.
P>P'), so characters, pictures, etc. can be easily seen on a display device in which display bodies are arranged in a matrix.

As explained above, according to the present invention, the display color can be easily displayed by energizing the electromagnets corresponding to the main rotating body and the reversing plate having the desired display color at once, which simplifies the electrical configuration. .

Further, in the case of a four-color display, for example, by providing a reversing plate on the display surface of the main rotating body, the display body interval can be narrowed, and characters, pictures, etc. can be easily seen as a matrix-like display device.

Furthermore, since the driving source is provided at the rear of the display, the display becomes smaller, and in a matrix display device, the visible distance for viewing characters, pictures, etc. is shortened.

Furthermore, since the display body can be made smaller, the overall size of the matrix-like display device can be made more compact.
