The configuration of the main parts of the panel and its functions will be explained using the top side view of FIG. 1.

In the figure, 1 is a flat pixel body or display element that forms the display surface of the side, 2 is a vertical shaft that rotatably supports the center of the pixel body, and 3 is on the left side of the pixel body 1. It is a buried magnetic piece.Only one pixel body 1 is shown in the drawing, which is supported by the vertical axis 2.

A plurality of them are arranged at regular intervals (pitch) in the vertical direction.

In the embodiment diagram, the number of elements in the plurality of arrays is five (IAI
However, a larger number may be arranged depending on the accuracy of panel display of characters and the size of the panel.

Further, the vertical shafts 2 on which a plurality of rotating pixel bodies are supported are arranged parallel to each other at equal pitches in the left-right direction in FIG. 9 to form a display surface. Thus, each pixel body 1 forming a rectangular display surface,
It is a mallet that rotates around the shaft 2 to invert and display the front and back sides. 11! The front and back sides of the element body or display element 1 are, for example, white or 1. A symmetrical color that is easy to identify, such as the j1 color, is added. Historically, 4 is a window clearing with the downward direction of the figure as the visual direction of the display.
(The front side of the display panel in Figure 2) is attached to the panel frame,
6. A transport heald provided in contact with the flat back surface of the pixel body;
In addition, 7 and 8 are left and right Z knees for tensioning the conveyor heald 6, and a heald drive unit 10 is connected to the 7 side of the pulley. 3 is a magnetic piece embedded in the 6111 part of the pixel body that rotates around the vertical axis 2; This is an electromagnetic drive unit consisting of a coil and an iron core with magnetic poles perpendicular to the feeding direction.

The electromagnet drive unit 9 is mounted at a position 1tli by dividing a part of the endless conveyance heald 6 as shown in the figure. Furthermore, the space 11 between the pixel body 1 is a rotational operation area for flipping the two pixel bodies from front to back. Furthermore, the double-headed arrow 12 shown in the figure indicates the direction of movement of the transport heald.

If the front view of the display panel in FIG. 2 is compared with both figures, the main structure of the panel of the present invention will become clearer.

In FIG. 2, a plurality of pixel bodies 1 are arranged in parallel over the entire display surface of the panel, with the supporting vertical shafts 2 having equal pinch D1 in the lateral direction (left and right direction).

Further, the pixel bodies 1 are arranged at equal pitches D2 in the vertical direction of the vertical axis 2. The top and bottom of the vertical axis are fixed to the panel display frame side of window brightness +J.

In Figure 2, 13 and 14 are the rotation axes of the pulleys 7 and 8, and If! It is a mechanism that moves the electromagnet drive unit 9 in the horizontal direction via the IT sending bell l-6.

Next, with reference to the top side views of FIGS. 3 and 4, the pulley 7 performs a held movement (, 5iiQj, display writing operation by inversion or non-inversion operation of the element body, or 7;-input erasing operation means). explain.

FIG. 3 is a state diagram of the first sentence level of the display panel shown in FIG. 1 at the initial stage of writing. (a) By moving the transport heald 6 in the direction of the arrow and energizing the electromagnetic coil 26 of the element drive unit 9,
In the figure (a) in which the flat pixel body 21 in the front position is reversed, the magnetic piece 3 is pulled up to the iron core 27 side and the reverse motion of the pixel body shown in the figure begins around the vertical axis 2. do. At a point in time when the figure (b) is subsequent to the figure (a), the two-pixel body 21 is pushed into the operating range 11 by the movement of the bell 1, and the display surface is inverted. However, at this point, the coil excitation is only one turn. Further, the pixel body 21 continues to be mechanically inverted at the edge 15 of the element driving section due to the HEL I-movement, and the inverted display drive of the ζ1 pixel 21 is completed after passing through the state shown in FIG.

At the same time as U), writing to the next pixel body begins.

Note that the pixel body 22 to be pasted at the pitch DI is displayed in reverse.
1! (c) In the state shown in the figure, the electromagnetic coil 26 is internally excited to invert the magnetic piece embedded in the pixel body 22 in the operation range 11.
, and performs a reversing operation using the same mechanical reversing operation as described above.

However, if the 9-pixel body 22 is a pixel body that does not require writing,
DIJ Kt of the coil 26 is not performed.

The top side view of FIG. 4 is an explanatory diagram of inverting and erasing the pixel body after loading. The figure shows an initial state of operation in which the pixel body 21 is not inverted.

For writing and erasing, the electromagnet drive section 9 is energized.

In addition, the transfer hell 1-6 can be moved in the opposite direction to that during writing, and one inversion element can be driven in a non-inversion manner (inversion drive).

The erasing of the old pixel body or the old pixel body of the display device of the present invention explained in the above d-detail has been explained by taking up one local element arranged in the lateral direction (horizontal direction). The drive control method A11 is adopted in which the electromagnets for driving the pixel bodies, which are vertically arranged in plurality at the pitch D2 in FIG. can be displayed as a fluid sign.

The panel that arranges the display elements has a configuration in which the back side is close to the conveyor belt surface, so for example, the elements that are in the process of reversing will not change their state due to external force. This is to prevent erroneous display after or before writing. In other words, there is a length of the conveyor belt that can be used to prevent erroneous display.

(Effects of the Invention) According to the fluid sign display device using the front and back surfaces of the pixel body described in detail in accordance with the above embodiment.

The writing of characters, etc., or the erasure after registration is done by an extremely simple means by driving the conveyor held in the past. , it requires less than half of the number of pixels, so there is an advantage that an economical display device can be realized.
