The attached end is inserted between the bent portions 31 and 32 of the bullets 27 and 28 of the selected display control head and engaged with the bent portion 31, and then the light receiving element 56 is inserted into the position detection plate 52. When the light receiving element 56 faces the part between the notches R1 and R2, the output from the light receiving element 56 becomes "0", and the shift register K of the drive circuit 70 is reset, and the address selection circuit F selects the memory circuit. The second parallel information for the display elements D12 to DN2 stored in H is read out and stored again in the shift register K, and at the same time, the selected display element among the display elements D11 to DNI mentioned above is moved beyond 90°. Then, a state is obtained in which the display surface d2 becomes the front side, and in the end, only the selected display element among the display elements D11 to DN1 is rotated by 180 degrees, and then the light receiving element 56 faces the notch R2. In this case, as in the case described above, the output terminals OE1 to OE of the drive circuit 70

When the information is "1" and "1", the information of "1", "0" and "0" and when the output of "0" is obtained in the binary display from the next light receiving element 56, "0","1", and "0" information, and when "0" output is obtained in the binary display from the next light-receiving element 56, the information "0", "0", and "1" are displayed, respectively. The obtained information is sequentially stored in the shift registers K1, K2, and K3, and when the output of the light receiving element 56 supplied to the input terminal I4 becomes "1", the shift register K1 is stored.
, K2 and K3 are stored at the output terminal OE11, respectively.

When the output from the light receiving element 56 becomes "0", the output terminals OE1, ~OE1N, oE21
~oE2N and OE3, ~OE3N can no longer obtain the outputs that had been obtained until now, and the shift registers Kl and K2
and K3 are reset, and address selection circuits F and F', memory circuits H and H', and data processing circuit G are reset as described above.
Then, the shift registers K1, K2, and K3 are controlled, respectively, and the information to be stored at the next address is sequentially read out from the storage circuits H1 and H2.The data processing circuit G is operated in the same manner as described above, and the information from this is stored in the shift registers. K1, K2, and K3, and if the output from the light receiving element 56 becomes "1", the shift register K1 is stored in the same way as described above.
, the information that can be stored in K2 and K3 respectively is the output terminal? OE11

This operation is then repeated.

In addition, the position detection plate 52 of the detection mechanism 51 of the drive device 3 has notches Rj, RSt, and Rs2 similar to the notches Rj, RSt, and Rs2, respectively, at positions above the notch RSt at intervals of LB.
S3 and Rs4 are provided respectively.

The above is the configuration of another example of the display panel to which the display element according to the third embodiment of the present invention is applied. According to this configuration, the horizontal rod 35 of the display conversion device 2 is now in the lower position. Assuming that the detection switch 62 is in the on state, if the power switch S of the drive circuit 70 of the drive device 3 is controlled to be on for a short period from such a state, the above-mentioned state in FIGS. 4 and 5 can be achieved. As in the case where the horizontal rod 35 is moved upward, and each time an output of "1" is obtained from the light receiving element 55, the shift registers K1K2 and K3 of the partitioning circuit 70 are moved upward.
The information of "1" from the data processing circuit G is stored in sequence, and this information is transferred to the output terminals OE11 to OE1N, OE21 to OE2 each time the light receiving element 55 outputs "0".
Electromagnets 29 and 1 of the display control heads E1 to EN of the display conversion device 2 are led to N and OE31 to OE3N.
29 and 130, so the electromagnets 29, 12
9 and 130 are both energized, so that the display element Dii of the display surface body 1 is placed on the display surfaces d, 130 as shown in FIG.
When the magnetic piece M3 is on the front side, the magnetic piece M3 exists at the rear lower end, so if it is attracted by the force of the electromagnet 29 and rotates 90 degrees, the next electromagnet 129 arrives because there is no magnetic piece at the rear lower end. Even when the next electromagnet 130 arrives, it is not rotated, so the display state is such that the display surface d3 is on the front side, and the display surface d4 is on the front side. In this case, since the magnetic piece M2 exists at the rear lower end, it is first attracted by the electromagnet 29 and
It is rotated by 0 degrees, and in this way, the magnetic piece M3 will be present at the rear lower end, so this will be attracted by the next electromagnet 129 and rotated another 90 degrees, but in this way, the magnetic piece will not exist at the rear lower end. As a result, even when the next electromagnet 130 arrives, it does not rotate, resulting in a display state in which the display surface d3 is on the front side, and when the display surface d2 is on the front side, the magnetic piece M1 is located at the rear lower end. Therefore, this is the electromagnet 29
is attracted and rotated by 90 degrees, and in this way the magnetic piece M2
exists at the rear lower end, so this is the next electromagnet 1.
29 and further rotated by 90 degrees, so that the magnetic piece M3 is present at the rear lower end, so it is further attracted by the next electromagnet 130 and rotated by 90 degrees, eventually moving the display surface d3 to the front side. When the display surface d3 is on the front side, it is not rotated by any of the electromagnets 29, 129, and 130 because there is no magnetic piece at the lower end, and the display surface d3 is on the front side. Therefore, by moving the horizontal rod 35 from the lower side to the upper side, the display elements D11 to DN1, D12 to DN2...
. . . All of DIM to DNM take a display state in which the display surface d3 is on the front side.

Then, the horizontal rod 35 reaches the upper position and the detection switch 6 is activated.
1 is turned on, the horizontal rod 35 is moved downward in the same manner as described above in FIGS. 4 and 5, and the light receiving element 5 is moved downward.
Every time an output of "0" is obtained from 6, the address selection circuits F and F', memory circuits H and H', data processing circuit G, and shift registers K1, K2, and K3 of the drive circuit 70 are controlled, and the memory circuits H and The electromagnets 29, 129 and 130 of the selected display control head of the display control heads E1 to EN of the display conversion device 2 are selectively energized according to the memory contents of H', and based on this, the display element D1 ,~DNI,
A selected display element among D12 to DN2...D1N to DNM is controlled to be converted so that one of its display surfaces d1, d2, and d4 is on the front side.

Then, the horizontal rod 35 reaches the lower position and the detection switch 6 is activated.
2 is turned on and a detection output of "1" is obtained from this, the fourth? and Moke 4 as in the case described above in FIG.
2 will be stopped.

As described above, according to the display panel using the display elements according to the third embodiment of the present invention, the display elements D11 to D
NI + DI ~ DN2... All the display surfaces d3 of D1M-DNM can be directed forward, and from this, a desired one of the display surfaces d1, d2, and d4 of a desired display element can be directed forward. can be directed forward, so the display element Di
If side d3 of j is set in advance as white, d1 as red, d2 as green, and d4 as blue, for example, colored characters, symbols, figures, and patterns can be displayed as desired as a whole. It has the great feature that such a display can be made with a simple structure as a whole.

Further, according to the display panel described above, the display element D has the configuration described above in FIG. It has the following characteristics.

As is clear from the above, the display element according to the third embodiment of the present invention also has the same major features as the display elements according to the first and second embodiments of the present invention.
