DESCRIPTION:
BRIEF SUMMARY
The object of this invention is display equipment using passive elements, especially for showing characters by dot-matrix array, which equipment consists: preferably using colors, rotatable about an axes, preferably about the axes coincident their median, information-carrying face, suitable for providing bits of information, preferably differing from that information conveyed by the background plate, and rotatable into the plane of the display surface of the background plate.
We are familiar with certain kinds of display equipment using passive indicating elements--such as described in the Hungarian patent application No. 3460/91, where the indicating elements are one or other specific shape and so formed to be pivoted about an axe coincident with their median, and the angle between their two extreme rotating positions being 90 degrees. The space between these two end-surfaces is completely filled by an indicating body and the middle section or whole width of this component has been permanently magnetized. Since, due to the effects of shading, the magnetic fields arising with this design do not permit miniature forms, this kind of indicating element is employed only in the segments of segmented display equipment.
The aim of this invention is to produce an arrangement whereby the shortcomings cited may be eliminated and, by this means, it will be made possible to use such indicating elements in dot-matrix units for the display of characters, and to reduce the dimensions of characters, respectively.
The basis of this invention is the realization that, if we position the magnetic parts within any two adjacent indicating elements in such a way that the magnetic component of one indicating element is one end of it and the magnetic component of the neighboring indicating element is in its other end, then the influence of the magnetic components upon each other is reduced. The result of this will be that the size of the indicating elements, and therefore that of the letters to be displayed, may be reduced. This means that such indicating elements of specific shape, which rotate through 90 degrees from one extreme position to the other--although with present-day techniques they are not yet suitable for producing dot-matrix characters, but are limited to numerical display consisting of segments, preferably of seven segments--they may, by virtue of the design in this invention, be made suitable also for the display of alphanumeric characters in dot-matrix form.
The essence of this invention is: direction of their axes, of which parts one piece with the information-carrying faces, at the same time end-surfaces, their dimension in the direction of the axis being not greater than half the distance between the end-surfaces, and the cross-section of magnetic body perpendicular to the axis, preferably identical with the cross-section of the end-surfaces perpendicular to the axis, are arranged in the vicinity of the end-surfaces of the indicating elements, preferably fastened to one or other end-surface of each indicating element.
BRIEF DESCRIPTION OF THE DRAWINGS
Here follows a more detailed description of this invention, with the help of the examples of performance, illustrated in the accompanying drawings, in which:
FIG. 1 shows the indicating elements arranged in rows and columns, in the axonometric realization, represented by one of the examples of performance of this invention;
FIG. 2 shows a few indicating elements fitted in the background plate with actuating coils and discs carrying control elements; and
FIG. 3 illustrates the cross-sectional view taken along the plane A--A in FIG. 2.
BEST MODE FOR CARRYING OUT THE INVENTION
The indicating elements 1 to be seen in FIG. 1 are illustrated arranged in rows and columns. Those indicating elements 1 positioned in the same row are linked preferably by a common axis 2, while they are free to rotate independently from each other on this axis 2. The axis 2 should be arranged expediently on the median of the indicating elements 1 of specific shape.
