Description

DETAILED DESCRIPTION OF THE INVENTION The subject of the invention relates to a bistable electromagnetic visible sign having a polarized magnet integrated in a rotatable armature.
It is particularly suitable for constructing a complete display block for reproducing alphanumeric codes. The bistable operation of these visual indicators makes it unnecessary to power them in each display state. This is because the reset is also performed by the reset nolus ξ. In a display block, visible markings, preferably arranged in a matrix, define specific image points within the display plane of such a display block! By selecting these image points, the nature of the code displayed in each case is determined.

However, such a visual indicator has the disadvantage that a relatively large amount of space is required for the reversal of the rocker piece. Furthermore, since the polarized magnet incorporated into the plate-like display surface is far away from the magnetic center of the electromagnet that controls the display surface, a relatively strong reset force is required. The miniaturization that is often desired for display blocks of this type with such visual indicators is hampered by the structure of known visual indicators that operate bistablely.

The problem on which the invention is based is therefore to create a bistable electromagnetic visible sign with a polarized magnet that can be constructed very small and that can be assembled into a rotatable armature in a simple manner to form a closed display block. There is something to offer. The present invention achieves this by: □. That is, the display surface of each armature is formed by one side or the other side of a square piece rotatable around an axis, and both poles of a polarized magnet surrounding the axis are formed within the square piece on one side of both sides. Each has its own range. Preferably, the polarized magnets are formed in the shape of a horseshoe, and the apex of each magnet is located on the bisector of the angle formed by both sides of the square piece. By having a plurality of such rectangular piece armatures on a common axis,
A plurality of such visual indicators can be easily and compactly grouped into display blocks. In order to display an alphanumeric code, a plurality of rows of armatures arranged on a common axis are grouped together in a matrix by holding frames arranged in a grid. In this case, the bottom plate of such a holding frame has holes distributed in a matrix to pass through pin-shaped magnetic cores with low residual magnetism corresponding to the armatures of the individual electromagnets.

The feeding pieces of these electromagnets are inserted into holes distributed in a matrix in an insulating block covered by a holding frame that holds the armature.

The drawing shows the structure of the display block.

In FIGS. 1 and 2, the electromagnetic coil 1, which is divided into a set coil and a reset coil, is inserted into a suitable hole in an insulating block 8, which is shown only schematically. The magnetic core 2 of the electromagnet with little residual magnetism is passed through the corresponding hole of the holding frame 3. The collar-shaped protrusion 9 of the holding frame 3 also serves as a display surface of a square piece rotatable around the axis 4, and a polarized magnet 5 is incorporated in this square shape. When the polarity of the electromagnet 1.degree. 2 changes, its position changes and the display surfaces 6 and 7 are alternated. Since both poles of the horseshoe-shaped polarized magnet 50 are close to the ends of the magnetic core 2, switching of the visible marker can be controlled with a relatively weak set pulse, reset pulse, or pulse.

FIG. 3 schematically shows the individual display features of four visible indicators forming part of the overall display block. Here, rotating armatures 31, 32. ．． 33.degree. 34 are pivotable in a row about a common axis 4. This oscillation is effected by the magnetic cores 35 to 38 of the electromagnets and the coils 39 to 42. Each of these coils is composed of a set coil and a reset fill, respectively, and the comb-like strips shown in FIG. 3 form the current path shown in FIG. 6.

That is, as shown in FIG. 6, the individual set coils and reset fills of different visual indicators are grouped into rows and columns, with separately led row conductors connected to respective isolation diodes D1 and D2. The determination of which coils to energize or demagnetize in order to visualize or extinguish a particular image point is determined by input terminals YSI or YL.
7 or by selecting the dead center XI to X5. In FIG. It will be done. Each row has two strips 54 and 5
6, the set coil of this row is energized via one strip, and the reset coil of this row is energized via the other strip. In this case, the feed conductors are connected to diodes D1 and D as already mentioned in connection with FIG.
2 has been inserted.

As shown in FIGS. 4 and 5, the individual electric 1F coils 40, 41, etc. are inserted into the holes 60 distributed in a matrix of the insulating block 8.
Holes 70, 71 and 72 provided at locations other than 0 are
The bottle-like protrusions of the connecting strips are passed through in the row and column directions. Each hole 60 is associated with three such holes for accommodating coil connection pieces.
As shown in FIG. 1 and FIG.
It supports a shaft 4 with 33 and 34. The display element constructed as shown in FIGS. 1 and 2 together with its horseshoe-shaped polarized magnet forms the original display surface of the entire display block as shown in FIG. 4. The shaft 4 is held by the holding frame 3.
It is carried out by Therefore, if a disturbance occurs in the operation of the individual rotatable armatures, it is only necessary to remove one holding frame 3, and there is no need to make any changes to the other components of the display block. The connections of the connecting strips 51 to 53 or 54, 56 are constructed as plug pins, which greatly simplifies the wiring. No special distribution strips or the like are required.
