Concerning the N pieces of information of M, these are respectively stored as M-th parallel information at the M-th address, and the N pieces of parallel information constituting the j-th parallel information are stored at the j-th address selected by the address selection circuit F. Information is sequentially read out one by one using read control pulses from the data processing circuit G.

...The Mth address is selected in sequence.

The output circuit J is configured to receive N pieces of J-th parallel information read out from the storage circuit H and output them.

The data processing circuit G receives sequential information from the output circuit J, generates a pulse for each piece of information, and supplies the pulses to the above-mentioned storage circuit H and shift register K as a read control pulse and a shift pulse, respectively. Further, a reset pulse RP for resetting the shift register K is also generated.

The shift register K has N digits, first, second, . . . The information that can be stored in N digits is read out at the same time.

If the switch S is turned on for a short period, an output signal is obtained from the output terminal 01, and while the output signal is obtained from the output terminal 01, the light receiving element 55 is connected to the input terminal ■3.
If a "1" detection output is supplied in the binary display, the data processing circuit G sequentially obtains "1" information in N binary displays, and N pulses CP are sequentially obtained, and the shift register K is sequentially shifted for each pulse of N pulses CP, and eventually N pieces of "1" information are stored in N digits of shift register K, and then the detection output from the light receiving element 55 becomes "
If the output from the light receiving element 55 becomes "1", the N pieces of information to be stored in the shift resistor K are output to the output terminals OE1 to OEN, respectively, and if the output from the light receiving element 55 becomes "1", the output terminals OE, to
At the same time that the output obtained by OEN can no longer be obtained, the shift register K is reset by the reset pulse RP, and as described above again, the N "" output from the data processing circuit G is
If the information of "1" is stored and the output from the light receiving element 55 becomes "0", the output terminal OE1 is stored as described above.
~OEN obtains an output, and then this operation is repeated, and furthermore, if the detection output from the detection switch 61 is supplied to the input terminal 1, the output terminal 0 is used instead of the output terminal 01.
The output signal is obtained from 2, and the light receiving element 5 is connected to the input terminal 4.
If an output signal is obtained at the output terminal 02 while the output of rOJ is being supplied in a binary display from 6, the address selection circuit F, the memory circuit H, the data processing circuit G, and the shift register K are controlled and the memory circuit N pieces of information that can be stored at the first address are sequentially read out from H and supplied to the shift register K via the output circuit J. On the other hand, the shift register K is controlled by N pieces of shift pulses CP, so that the N pieces of information are information is stored in the N digits of the shift register K, and then the light receiving element 56 is supplied to the input terminal 4.
When the output from the light receiving element 56 becomes "1", the N pieces of information to be stored in the N digits of the shift register K are led out to the output terminals OE, ~OEN, and then the output from the light receiving element 56 becomes "0". The information derived from the output terminals OE1 to OEH can no longer be obtained, and the shift register K is reset by the reset pulse RP.
Then, the address selection circuit F, memory circuit H, and data processing circuit G are controlled in the same way as described above, and N pieces of information to be stored at the second address are sequentially read out from the memory circuit H. The information is sequentially stored in the shift register K, and then when the output from the light receiving element 56 becomes "1", the information that can be stored in the shift register K is led out to the output terminals OE1 to OEN as described above, and then such operation is performed. If this is repeated and a detection output of "1" is supplied from the detection switch 62 as a binary value to the input terminal 2, no output will be obtained from the output terminal 02.

Furthermore, as is clear from the above, the electromagnet 29 of the display control head E of the display conversion device 2 is capable of displaying information obtained at the output terminal OEi of the drive circuit 170 in binary form.
1", the electromagnets 29 of the display control heads E1-1, E1+,
The magnetic pole plate of the electromagnet 29 on the display control head E1 side, that is, the magnetic pole plate 23R of the right electromagnet 29 of the display control head E as seen in FIG. 23L are energized so that they have the same polarity.

For this purpose, for example, if the winding directions of the coils 21 of the electromagnets 29 of the display control heads E1 to EN are the same, for example, the heads E1 and E2, E5 and E6j...
For example, the coil 21 of the electromagnet 29 has output terminals OE, OE2, O from the winding start side to the winding end side.
Even though a current is applied based on the information of "1" obtained from E, and OE6..., the remaining heads E3 and E4 p E
The output terminal O E 3 is connected to the coil 21 of the electromagnet 29 of 7 and E8, .

For example, if a current is applied to head E1 based on the information of "1" obtained from the output terminals OE, , OB2, . and the winding direction of the coil 21 of the electromagnet 29 of E2+E5 and E6... and the winding direction of the coil 21 of the electromagnet 29 of the remaining heads E3 and E4, E7 and E8... Conversely, for example, the magnetic pole plates 23L and 23R of the electromagnet 29 of the heads E1 and E2, E5 and E6, etc. are the north pole and the south pole,
Remaining magnetic heads E3 and E41E7 and E8...
Contrary to the above, the magnetic pole plates 23L and 23R of the electromagnet 29 may be configured to have an S pole and an N pole, respectively.

The above is the configuration of the first embodiment of the present invention. According to this configuration, the horizontal rod 35 of the display conversion device 2 is currently in the downward position and the detection switch 62 is in the on state. In this case, if the power switch S of the drive circuit 70 of the drive device 3 is turned on for a short period of time, the output terminal 0
Output from 1? As a result, the moke 42 is rotationally driven in the forward direction, and the strips 38 and 41 are driven clockwise as viewed in FIG. 2, and the horizontal rod 35 is moved upward. When the light receiving element 55 is moved, an output of "1" is obtained from the light receiving element 55 because it faces the notch R, 2 of the position detection plate 52, and in response to this, the drive circuit 70 is activated. shift register K
Information of "1" is sequentially stored in all digits by the data processing circuit G, and then the horizontal rod 35 moves further and the light receiving element 5
If 5 faces the part between notches R, 2 and RM, the output from this will be "0" and output will be obtained from the output terminals OE, ~OEN as described above, so the display control head The electromagnet 29 of Ei is energized, and in this state, the electromagnet 29 of the display control head E1 is connected to the display element I)+M.
- Since it faces the lower end of the DNM, the display element DiM
is on the lower end side of the magnetic piece M, that is, the display surface d2
If the magnetic piece M of the display element DiM is on the front side, the magnetic piece M of the display element DiM is attracted by the electromagnet 29 of the display control head Ei, as shown in FIG. 6A. The end of the side marked with M is the bullet 27 and 2.
When the horizontal rod 35 is inserted between the bent portions 31 and 32 of No. 8 and engaged with the bent portion 32, the horizontal rod 35 moves further upward and the light receiving element 55 faces the notch RM. Since an output of "1" is obtained from the light receiving element 55, no output is obtained from the output terminals OE1 to OEN as described above, and the electromagnets 29 of the display control heads E1 to EN become de-energized, and the drive circuit 70 N pieces of new "1" information from the data processing circuit G are stored in the shift register K, and the above-mentioned display element DiM is further rotated over 900 degrees, and the display screen changes through the state shown in FIG. 6B. d, is on the front side, and the display element DiM is eventually rotated 1800 times, and as the horizontal rod 35 moves, the display elements Di(M-1)...1...D1+Di1
180 only when those magnetic pieces M exist on the lower side in sequence.
The display elements DIl~DN1+ DI2~DN2
+... A relationship is obtained in which all of the DIM-DNMs have the display surface d1 on the front side.

Then, the horizontal rod 35 reaches the upper position and the detection switch 6 is activated.
1 turns on and from this, a detection output of "1" is obtained on the binary display? For example, based on this, the output terminal 02 of the drive circuit 70
Now, an output is obtained at the output terminal 01 in place of the output that has been obtained up to now, and therefore the moke 42 is driven to rotate in the opposite direction to the case described above, and the strips 38 and 41 are rotated counterclockwise as seen in FIG. As a result, the horizontal rod 35 is moved from the upper side to the lower side, and the light receiving element 56 is moved to the position detection plate 5.
2, an output of "0" is obtained from the light receiving element 56, and the memory circuit H, address selection circuit F, data processing circuit G and shift circuit of the drive circuit 70 The register K is controlled to read out the first parallel information for the display elements DIl to DN1 to be stored in the storage circuit H and stored in the shift register K, and then the horizontal rod 35 is lowered and the light receiving element 56 is moved to the notch R.
1, from this light receiving element 56
By obtaining the output ``, an output is obtained from the output terminal corresponding to the information ``1'' among the N pieces of information stored in the shift register K among the output terminals OE1 to OEN of the drive circuit 70, and therefore the display The electromagnet 29 of only the selected display control head among the climate control heads E1 to EN is energized,
Based on this, the electromagnet 2 of the selected display control head
Only the selected display element among the display elements D1 to DNI facing the display element 9 has the magnetic piece M attached thereto attracted by the electromagnet 29 and rotated clockwise as seen in FIG. 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 5.
2, 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 D1 to DN2 stored in H is read out and stored again in the shift register K, and at the same time, the number of selected display elements among the display elements Dll to DNI described above exceeds 900. Then, a state is obtained in which the display surface d2 becomes the front side, and eventually only the selected display element among the display elements DIl to DN+ is rotated by 180 degrees, and then the light receiving element 56 faces the notch R2. Similarly to the case described above, an output is obtained from the output terminal corresponding to the information "1" among the N pieces of information stored in the shift register K among the output terminals OE1 to OEN of the drive circuit 70. As in the case described above, only the selected display element among the display elements DI2 to DN2 is rotated clockwise as viewed in FIG.
The following display elements D13 to DN3+ DH to DN4...
... Only the selected display element in the DtM-DNM is rotated 1800 times, and the horizontal rod 35 reaches the lower position, the detection switch 62 is turned on, and a detection output of "1" is obtained. In this case, the output that has been obtained until now from the output terminal 02 can no longer be obtained, and the rotation of the motor 42 is stopped.

According to the first embodiment of the present invention as described above,
Display element DIl~DNtl DI2~DN2 +...
...This can be done as long as all the display surfaces d1 of D1M-DNM can be turned to the front side, and information can be stored in the memory circuit of the drive circuit 70 in a desired pattern. The display surface d2 of a desired display element can be set to the front side according to
t D12~DN2...DtM"DNM can display characters, symbols, figures, and patterns as desired as a whole, and such display can be done with a simple configuration as a whole. It has the following.

In addition, a pair of display surfaces d1 and d where the display element D.
1 in a pair of corners of the plate-like block body 4 formed by forming 2
The display surfaces d1 and d are arranged with magnetic pieces M arranged at the other corners except for one corner, and are pivotally supported on the plate-like block body 4.
It has an extremely simple structure in which the shaft hole 7 is formed so that the display element 2 lies in a vertical plane, and therefore the distance between the display element 2 and the adjacent display element can be made small. Furthermore, since the display surface of the display element is placed within a vertical plane, there is no need to provide a separate position regulating means, so that the entire device can be simplified and miniaturized.

Further, according to the first embodiment of the present invention described above, the electromagnets 29 of the display control heads E1 to EN are connected to the display control heads E1.
Display control head E of electromagnet 29 of i-1 and Ei+1
Since the magnetic pole plates on the first side are energized so that they have the same polarity, all the display surfaces d1 of the display face face forward, and then the display surface of the desired display element is energized. Since d2 is set to the front side, the display surface d2 of only the desired display element can be reliably set to the front side.

In other words, for all display control heads, the electromagnet 2
9 is energized so that the magnetic pole plate 23H on the right side is energized, for example, with the N pole, and the magnetic pole plate 23L on the left side is energized with the S pole. The display elements D(i-1)j and D(i-1-+)j corresponding to the control heads EI-1 and E1+ are used as desired display elements, and the display surface d2 thereof is placed on the front side. When the control heads E, , and E1+1 are energized, the magnetic pole plate 23 on the head FEi side of the head Ei,
If R is, for example, the north pole, the magnetic pole plate 23L on the head E1 side of head EI+1 becomes the south pole, so head Ei
, magnetic pole plate 23R and head Ei+, magnetic pole plate 23L
A magnetic flux flows between them, and for this reason, the same thing happens as if the head Ei were energized, and therefore the desired display element D(i
-1) The display surfaces d2 of i and D(i-H)j face forward, and the display surfaces d2 of undesired display elements D... also face forward.

However, in the case of the first embodiment of the present invention described above, the magnetic pole plate 23R on the head E side of the head Ei and the head E,
The magnetic pole plates 23L on the head E side of +1 are both N poles, for example, and the magnetic pole plates 23R of the head Ei and the head Ei+,
A magnetic flux flows between the magnetic pole plates 23L, and therefore the display surface d2 of the undesired display element D does not face forward.

Furthermore, heads Ei and E sandwiching heads E and Ei+.
Display elements D(il)J and D(i+2) corresponding to i+2
) j as the desired display element, and when the heads Ei-1 and E1+2 are energized, the head Ei of the head Ei-1
Although magnetic flux does not flow between the magnetic pole plate on the side of the head E1+2 and the magnetic pole plate on the head Ei+1 side of the head E1+2, since the heads Ei and 'Ei+1 are inserted between the two magnetic pole plates, the distance between the two magnetic pole plates is small. Therefore, no magnetic flux actually flows between the two magnetic pole plates,
Therefore, the undesired display surfaces d2 of the display elements D and D(i+t)j corresponding to the heads E1 and E1-1 are not directed to the front side.

Next, a second embodiment of the present invention will be described with reference to FIGS. 7 and 8. In this example, parts corresponding to those in FIGS. Although omitted, the display element D of the display panel 1 in the configuration of FIGS. 1 and 2

That is, as is particularly clear in FIGS. 9A and 9B, the display element D of the display surface 1 has two pairs of opposing display surfaces d1 and d2 displaying different colors, and ? A rectangular prism-shaped block body 10 that is square when viewed from the side and formed by forming d3 and d4.
The magnetic pieces M are disposed at the corners other than the corners formed by the display surfaces d1 and d4 of 4 in such a manner that they extend in the left-right direction, and are supported pivotally by the square columnar block body 104. The shaft hole 101 is formed so that the facing display surfaces d1 and d2 or d3 and d4 lie within a vertical plane.

In this case, the shaft hole 107 of the display element Dij has a square cross section when viewed from the side, and its two pairs of opposing corners are located at positions that can rotate by 45 degrees with respect to the corners of the square columnar block body 104. The display surface dl of the shaft hole 107,
d2 t The corners opposite to d3 and d4 are g1 and g, respectively.
2, g3, and g4, if the shaft 108 is loosely inserted into the shaft hole 107 as shown by the chain line, the shaft 108 will fit into the corner g.
, and g2, the display surfaces d3 and d4 are in the vertical plane, and in the state of engagement between the corners g3 and g4, the display surfaces d1 and d2 are in the vertical plane, respectively. being done.

and Rs4 are provided, respectively.

Also, as is clear from the above, the electromagnets 29, 129 and 130 of the display control head Ei of the display conversion device 2 have binary information obtained at the output terminals OE,i, OE2i and OE31 of the drive circuit 70, respectively. When the display indicates "1", the electromagnets 29 of the display control heads E1 to EN are energized.
129 and 130 are the electromagnets 29 of the display control heads Ei-1 and Ei+1, as in the case described above in FIG.
, 129 and 130 on the display control head E1 side, that is, the magnetic pole plate ? As seen in the diagram, electromagnet 2 of display control head Ei
The magnetic pole plates 23R on the right side of magnets 9, 129, and 130 and the magnetic pole plates 23L on the left side of electromagnets 29, 129, and 130 of display control head Ei+1 are energized to have the same polarity. .

129 and 130, so the electromagnets 29, 1
29 and 130 are both energized, and therefore, when the display element D of the display face member 1 is on the front side with respect to the display surface d1 as shown in FIGS. 9A and B, the magnetic piece M3 is located at the rear lower end. Since there is a magnetic piece in the rear lower end part, it is attracted by the energization of the electromagnet 29 and rotates 900 times, but if it rotates 900 times, there is no magnetic piece at the rear lower end, so even if the next electromagnet 129 arrives, this electromagnet 129 Similarly, even if 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 when the display surface d4 is on the front side, the magnetic piece M2 is at the rear lower end. , so this is first attracted by the electromagnet 29 and rotated 90',
In this way, the magnetic piece M3 will be present at the rear lower end, so it will be attracted by the next electromagnet 129 and rotated an additional 900 times. Even when the next electromagnet 130 arrives, it does not rotate and the display state ends up with the display surface d3 on the front side. Furthermore, when the display surface d2 is on the front side, the magnetic piece M exists at the rear lower end, so this is the first thing to do. The magnetic piece M2 is attracted by the electromagnet 29 and rotated by 90 degrees, so that the magnetic piece M2 is present at the lower rear end, and is then sucked by the next electromagnet 129 and rotated by another 90 degrees. Since M3 is located at the rear lower end, this is the next electromagnet 13.
0 and rotated 900 times, resulting in a display state in which the display surface d3 is on the front side, and when the display surface d3 is on the front side, the electromagnets 29, 129 are removed because there is no magnetic piece at the lower end. and 130, the display state in which the display surface d3 is on the front side is maintained, and therefore, by moving the horizontal rod 35 from the lower side to the upper side, the display elements DIl~DNt + DI2~DN2...・D1

1 is turned on, the horizontal rod 35 is moved downward in the same manner as described above in FIGS. 1 and 2, and the light receiving element 5 is turned on.
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 Kl, K2, and K3 of the drive circuit 70 are controlled, and the memory circuit H is controlled. 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 stored contents of the display converter 2 and the display control head E1 to H'. DIl～DNI
t D12 to DN2 . . . The selected display element in DtM-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, the motor 4 is turned on as in the case described above in FIGS.
