Beschreibungseinleitung:Description Introduction:
Die Erfindung bezieht sich auf ein Blindenschrift Lesegerät mit einem flächenhaften Darstellungs-Träger mit erhabenen Rastpunkten, die von selektiv durch Öffnungen in der Oberfläche 5 des Darstellungsträgers hindurch ragenden Stiften gebildet werden. Der Darstellungsträger besteht aus einem, eine geschlossene Schleife bildenden Band, das um zwei rotierende Walzen mit parallelen Achsen läuft.The invention relates to a Braille reading device with a planar display support with raised detent points, which are formed by selectively protruding through openings in the surface 5 of the display medium through protruding pins. The display medium consists of a closed-loop band running around two parallel-axis rotating rollers.

Es sind elektromechanisch betätigbare Ausgabegeräte für Blindenschrift bekannt, die mit einem Tableau versehen sind, das ein Lochraster mit der Grundstruktur der Blindenschriftzeichen aufweist. In diesen Löchern befinden sich Stifte, die einzeln mittels Piezo-Biegebalken nach oben bewegt werden können, derart, dass die nach aussen ragenden Stifte in ihrer Gesamtheit 15 di,e Blindenschriftzeichen repräsentieren. Alle diese bekannten Ausführungen von Lesegeräten dienen der Präsentation eines Textes in einem Umfang, der durch die Größe des Darstellungsfeldes bestimmt ist. Wenn mit Hilfe solcher Geräte ein längerer Text in tastbarer Form dargestellt werden soll, muss dieser in Abschnitte entsprechend der Größe des Aufzeichnungsfeldes unterteilt, abgespeichert und dieser Speicherinhalt in elektrische Signale umgesetzt werden. 20There are known electromechanically actuated braille output devices which are provided with a panel having a breadboard with the basic structure of Braille characters. In these holes are pins that can be individually moved upwards by means of piezo-bending beams, such that the outwardly projecting pins in their entirety represent 15 di brakes. All of these known types of readers are for the presentation of a text to an extent that is determined by the size of the viewport. If a longer text is to be displayed in palpable form with the aid of such devices, it must be subdivided into sections corresponding to the size of the recording field, stored and this memory content converted into electrical signals. 20
Aus dem Europäischem Patentamt Patent Nr. 157 174 ist ein Blindenschrift-Lesegerät mit einem flächenhaften Darstellungsträger mit erhabenen Rastpunkten, die von selektiv durch Öffnungen in der Oberfläche des Darstellungsträgers hindurchragenden Kugelkalotten gebildet werden, bekannt, wobei der Darstellungsträger aus einem eine geschlossene Schleife bilden-25 den über zwei, um parallele Achsen rotierenden Walzen umlaufenden Band aus flexiblen Material besteht, bei dem die für die Kugelkalotten vorgesehenen Öffnungen an der Schleifen-Aussenseite des Bandes angeordnet sind, das im oberen, die eine Lesezone bildenden Teil der Schleife über eine Auflageplatte und im unteren Teil der Schleife durch einen Stahlkugel-Behälter geführt ist, und wobei der Darstellungsträger mit einer senkrecht zur Bewegungsrich-30 tung des Bandes angeordneten, elektromagnetisch betätigten Auswahlvorrichtung versehen ist.From European Patent Office Patent No. 157174 there is known a braille reading device having a planar display carrier with raised engagement points formed by spherical caps selectively protruding through openings in the surface of the presentation carrier, the presentation carrier being one of them forming a closed loop consists of two, rotating about parallel axes rotating rollers band of flexible material, wherein the provided for the Kugelkalotten openings on the loop outside of the band are arranged in the upper, a reading zone forming part of the loop on a platen and the lower part of the loop is guided through a steel ball container, and wherein the display carrier is provided with a perpendicular to the direction of movement of the tape-direction, arranged electromagnetically actuated selection device.
Dabei bleibt es aber eine schwierige Aufgabe, lose Kugeln definiert zu führen, einzusammeln und zu verteilen. 35 Die Druckschrift FR 2670935 A1 (Phalippou J.A.E.) zeigt ein flächiges Braille-Display, welches aus einem Band mit darin gelagerten Stiften besteht. Die Stifte werden elektromechanisch aus-und eingefahren. Die Stifte führen beim Ein- und Ausfahren eine Schraubbewegung aus.However, it remains a difficult task, defined loose balls to lead, collect and distribute. 35 The document FR 2670935 A1 (Phalippou J.A.E.) shows a planar Braille display, which consists of a band with pins mounted therein. The pins are electromechanically extended and retracted. The pins perform a screwing during retraction and extension.
Die Patentschrift US 4 586 903 A (Burchart J.) zeigt ebenfalls ein Braille-Display, welches aus 40 einem Band besteht. Im Band sind konkav/konvex- geformte Plättchen eingesetzt, welche entweder einen konvexen oder konkaven Zustand einnehmen können. Alle Plättchen werden durch eine Resetrolle an der Bandunterseite in den selben Zustand gebracht und anschließend durch Stempel selektiv in den 2. Zustand, je nach Information gebracht. 45 Aufgabe der Erfindung:The patent US 4,586,903 A (Burchart J.) also shows a Braille display, which consists of a band. In the band concave / convex shaped plates are used, which can take either a convex or concave state. All platelets are brought into the same state by a reset roller on the underside of the belt and then brought selectively into the second state by stamp, depending on the information. 45 Object of the invention:
Der Erfindung liegt somit die Aufgabe zugrunde, ein Blindenschrift Lesegerät der eingangs geschilderten Art so zu gestalten, dass eine vorteilhafte großflächige Darstellung kombiniert wird mit einer sehr flachen Mechanik um den Darstellungsträger mit einer druckempfindlichen, so positionsauflösenden Folie unterlegen zu können. Lösung der gestellten Aufgabe:The invention is therefore based on the object to design a Braille reading device of the type described so that an advantageous large-scale representation is combined with a very flat mechanism to the display medium with a pressure-sensitive, so position-resolving film inferior. Solution of the task:
Die Aufgabe wird dadurch gelöst, dass die, die Rastpunkte bildenden Stifte (1) durch quer 55 liegende Achsen (9) im Band fixiert und drehbar gelagert sind und so durch vertikales Aufklap-The object is achieved in that the, the detent points forming pins (1) fixed by transversely lying axes (9) in the band and are rotatably mounted and so by vertical Aufklap-
