Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device in which a large number of display bodies are arranged in a matrix to display characters, numbers, etc., as shown in FIG. 1, for example.

First, a conventional display device will be explained with reference to FIGS. 2 and 3.

FIGS. 2 and 3 show a six-sided display, including a frame 101, a display body 103 made of a hexagonal cylinder rotatably supported by the frame 101 via a bearing 102, and A rotor 104 made of a permanent magnet coupled with a frame 101 is located parallel to the axial direction of the display body 103 and is arranged around the bearing 102.
A magnetic pole is supported at one end, and the other magnetic pole is connected to the rotor 1.
6 electromagnets 106, 106, 10 facing 04
It is composed of 7, 108, 109, and 110.

2, for example, in the state shown in FIG. 2, N is applied to the electromagnet 105 by energizing the coil 111.
When a pole is generated, the rotor 104 made of a permanent magnet becomes 1
The rotor 104 rotates in the direction of the arrow 17, and the S pole of the rotor 104 stops at a position facing the electromagnet 105 as shown by the broken line in FIG. 3, changing the display surface of the hexagonal cylinder.

Similarly, if you want to change to another display color, use the coil 112
, 113, 114, 115, 116, the electromagnets 106, 107, 108, 109, 110
By generating an N pole in either of the permanent magnets 104, the S pole of the permanent magnet 104 is attracted to the energized electromagnet, and other display colors can be displayed.

However, in the conventional display device described above, since six colors are displayed using one hexagonal cylinder, the outer diameter of the hexagonal cylinder becomes very large. In this case, the distance between the display body (hexagonal column) and the display body becomes large, making it extremely difficult to see characters, pictures, etc.

Since there are six electromagnets with coils wound between the display and the frame, it is not possible to construct a display whose radius is smaller than the radius from the center of the display to the outer surface of the coil, so a large number of display bodies were used to form a matrix. In a display device, in order to make characters, pictures, etc. easier to see, it is not possible to make the display body small and increase the number of display bodies.

Furthermore, since the display body cannot be miniaturized, it is not possible to obtain a compact matrix-like display device.

Height of the electromagnet with a coil wound between the display and the frame x
Since this takes up more space, the entire display becomes larger.

Since one electromagnet is required for one display color, the cost increases.

Due to the above-mentioned reasons, a small display body cannot be obtained, and there are drawbacks such as large hunting when the display element is stopped.

The present invention eliminates the above-mentioned conventional drawbacks, and provides a compact display device capable of displaying multiple colors by dividing the display body into a plurality of parts to reduce the display body and the interval between the display bodies. This is what I am trying to do.

An example of this will be described below with reference to FIGS. 5 to 13.

It is provided at a position facing the rotation locus of and is composed of an electrode 28 and a coil portion 29.

The electromagnets 21, 22, and 27 are fixed to, for example, a frame 3, and the frame 3 is made of a non-magnetic material such as brass or plastic.

, FIGS. 10 to 13 show a nine-sided display according to another embodiment of the present invention.

For example, one sub-rotating body 35 has a white display surface 38, a red display surface 39, and a blue display surface 40, and the sub-rotating body 36 has a yellow display surface 41, a green display surface 42, and a black display surface. The other sub rotating body 37 has a purple display surface 4.

Electromagnets 67 and 58 are provided at positions facing the rotational locus of the permanent magnet 34 as shown in the figure, and are composed of electrodes 59 and 60 and a coil portion 6L62.

63 and 64 are electromagnets, which represent the display color plane, and are the permanent magnets 47 and 48 of the sub rotating bodies 35, 36, and 37 when

The electromagnets 57, 5B, 63, and 64 are fixed to a frame 33, for example, and the frame 3 is made of a non-magnetic material such as brass or plastic.

Next, its operation will be explained.

In the first embodiment of the present invention shown in FIGS. 5 to 8, if it is desired to display a white display surface 8, for example, the electromagnet 22 is energized and an N pole is generated at the tip of the iron core 24 as shown in FIG. , the S pole of the permanent magnet 4 of the main rotating body 1 is attracted to this N pole, the main rotating body 1 rotates, and the main rotating body 1 is at a position where the N pole generating part of the iron core 24 and the S pole of the permanent magnet 4 face each other. stops.

Next, when the electromagnet 27 is energized and an S pole is generated at the tip of the iron core 28 as shown in FIG. 5, the N pole of the permanent magnet 14 of the sub rotating body 5 is attracted to this S pole, and the sub rotating body 5 rotates. iron core 28
Since the S-pole generation part of the permanent magnet 14 and the N-pole of the permanent magnet 14 are stopped at opposing positions, a white display surface 8 can be displayed, and a white color can be displayed.

If the electromagnets 22 and 27 are cut off, the main rotating body 1 is held by the magnetic attraction between the permanent magnet 4 and the iron core 24,
Since the sub rotating body 5 is held by the magnetic attraction between the permanent magnet 14 and the magnetic material 18, the state in which the white display surface 8 is displayed can be maintained even in a power outage state.

This makes it an energy-saving type. Next, yellow display surface 11
If you want to display , the electromagnet 22 is energized and an S pole is generated at the tip of the iron core 24 as shown in Fig. 8.The N pole of the permanent magnet 4 of the main rotating body 1 is attracted to the S pole of the main rotor 1, and the main rotation The body rotates as shown by the arrow A and stops at a position where the S-pole generator of the iron core 24 and the N-pole of the permanent magnet 4 are opposed to each other.

Next, when the electromagnet 21 is energized and an S pole is generated at the tip of the iron core 28 as shown in FIG. 8, the N pole of the permanent magnet 15 of the sub-rotating body 6 is attracted and the sub-rotating body 6 rotates as shown by the arrow B. Since the iron core 28 stops at a position where the S-pole generation part and the N-pole of the permanent magnet 14 face each other, the yellow display surface 11 can be displayed in yellow.

Similarly, when it is desired to display various display colors, various displays can be achieved by changing the magnetic poles of the iron cores of the electromagnets 21 and 27 or the electromagnets 22 and 27.

In this case, as shown in FIG. 4 and FIG. 5 for comparison, when one display surface of equal width is used, according to this configuration, the element spacing ( P>P'
) can be narrowed, making it easier to see characters, pictures, etc. on a display device in which a large number of display bodies are arranged in a matrix.

A second embodiment of the present invention shown in FIGS. 10 to 13 will be described.

For example, if you want to display the white display surface 38, the electromagnet 57
When the S pole of the permanent magnet 34 of the main rotating body 31 is repelled and the N pole is attracted, the main rotary body 31 rotates and the S pole of the permanent magnet 34 of the main rotating body 31 is rotated. The magnet stops at a position where the S-pole generating part 59 and the N-pole of the permanent magnet 34 face each other.

Next, when the electromagnet 63 is energized and an S pole is generated at the tip of the iron core 65 as shown in FIG. Since the generator stops at a position where the N pole of the permanent magnet 47 faces each other, a white display surface 38 can be displayed and a white color can be displayed.

When the electromagnets 57 and 63 are de-energized, the main rotating body 31 is held by the magnetic attraction between the permanent magnet 34 and the iron core 59.
Since the auxiliary rotating body 35 is held by the magnetic attraction of the permanent magnet 47 and the magnetic materials 51 and 52, the state in which the white display surface 38 is displayed can be maintained even in a power-off state.

Therefore, like the previous embodiment, it becomes a power saving type.

Next, when you want to display the black display surface 43, when the electromagnet 58 is energized and an S pole is generated at the tip of the iron core 60 as shown in FIG. 13, the S pole of the permanent magnet 34 of the main rotating body 31 repels
The poles are attracted, and the main rotating body rotates as shown by the arrow C, stopping at a position where the S-pole generator of the iron core 60 and the N-pole of the permanent magnet 34 are opposed to each other.

Next, when the electromagnet 63 is energized and an N pole is generated at the tip of the iron core 65 as shown in FIG. It rotates as shown by the arrow and stops at a position where the N-pole generating part of the iron core 65 and the S-pole of the permanent magnet 48 face each other, so that the black display surface 43 can be displayed and a black color can be displayed.

Similarly, if you want to display various display colors, use the electromagnet 63.
Alternatively, various displays can be made by combining 64 and 57 or 58 and changing the magnetic poles of the iron core.

In this case, as shown in FIGS. 9 and 10, when a display surface with equal IJ is used, this configuration can be compared with the conventional 9-prismatic display shown in FIG. ) can be narrowed, making it easier to see characters, pictures, etc. on a display device in which a large number of display bodies are arranged in a matrix.

As explained above with reference to the embodiments, according to the present invention, by dividing the display body into a plurality of pieces, the interval between elements can be narrowed, and in a display device in which a large number of display bodies are arranged in a matrix, characters, pictures, etc. can be easily seen. .

Furthermore, since one drive source is provided at the rear of the display, the display becomes smaller, and therefore the viewing distance when viewing characters, pictures, etc. in a matrix display device is shortened.

Furthermore, since the display body becomes smaller, the overall configuration of the device becomes more compact.

Furthermore, conventionally, one electromagnet was required for one display color, but in the present invention, for example, three drive sources are required for a six-color display, and four drive sources are required for a nine-color display. Since it is a power source, the number of driving sources is reduced.

Furthermore, since the display body is made smaller by dividing the display body, there are great effects such as less hunting when the display body is stopped.
