Abstract
Description
Zum Prüfen von Schriften sind verschiedene Verfahren und Vorrichtungen bekannt. Sie werden z. B. in Banken zur Prüfung von Dokumenten verwendet. Diese Schriftprüfer arbeiten mit optischen Systemen. Die Prüfung erfolgt nach dem auf einem Formular unterschrieben wurde (off-line). Das Dokument wird in einem gesondertem Gerät manuell oder automatisch eingezogen und mit einer zuvor hinterlegten Unterschrift verglichen. Ein sofortiger Vergleich (on-line) ist nicht möglich. Die Prüfung erfolgt überwiegend zweidimensional, also Länge und Breite.Various methods and devices are known for checking fonts. she z. B. used in banks to check documents. These auditors are working with optical systems. The test is carried out according to the signed on a form was (off-line). The document is manually or automatically in a separate device confiscated and compared with a previously stored signature. An instant comparison (on-line) is not possible. The test is predominantly two-dimensional, i.e. length and Width.
Aus den US-Patentschriften 4 131 880 und 4 111 052 ist bekannt, zum Erkennen einer Un terschrift einen Drucksensor im Schreibstift anzuordnen.It is known from US Pat. Nos. 4,131,880 and 4,111,052 to recognize an Un to arrange a pressure sensor in the pen.
Aus EP 0 560 356 A2 ist bekannt, die beim Schreiben auf die Schreibunterlage wirkenden Kraftverläufe und deren Änderungen unmittelbar zu messen und auszuwerten. Für eine Massenanwendung als Konsumgerät genügen die so erfaßten und zur Verfügung gestellten Werte vollkommen.From EP 0 560 356 A2 it is known that those which act on the writing pad when writing Force courses and their changes to be measured and evaluated immediately. For one Mass use as a consumer device is sufficient for those recorded and made available Perfect values.
Nachteilig bei den vorgenannten Verfahren ist, daß entweder ein Spezialstift, ein Scanner oder ausschließlich die nach unten in die Platte wirkenden Kräfte zur Verifikation der Schrift genutzt werden. Dies ist für wissenschaftliche, forensische und medizinische Forschung und Anwendung nicht ausreichend.A disadvantage of the aforementioned methods is that either a special pen or a scanner or only the forces acting down into the plate to verify the writing be used. This is for scientific, forensic and medical research and Application insufficient.
Aufgabe der Erfindung ist es, diese Nachteile zu beseitigen und ein Verfahren und eine Vor richtung zu schaffen, die auch die seitlich beim Schreiben auftretenden Kräfte erfaßt und auswertet.The object of the invention is to eliminate these disadvantages and a method and a to create direction that also detects the forces occurring laterally when writing and evaluates.
Diese Ausgabe wird erfindungsgemäß dadurch gelöst, daß die Schreibfläche oder die Schreibunterlage den Schreibdruck, die Schreibdruckänderungen und zusätzlich die seitlich auf die Schreibfläche oder die Schreibunterlage wirkenden Kräfte mißt. Das seitliche Kräfte beim Schreiben auftreten ist bekannt. Die beim Schreiben auf das Blatt wirkende Reibungs kraft des Schreibgerätes zwingt den Schreiber eben dieses Blatt mit der anderen Hand- oder einer mechanischen Vorrichtung wie eine Klammer- festzuhalten.This output is achieved according to the invention in that the writing surface or the Writing pad the writing pressure, the writing pressure changes and additionally the side measures forces acting on the writing surface or the writing surface. That side forces occur when writing is known. The friction when writing on the sheet By virtue of the writing instrument, the writer is forced to write this sheet with the other hand or a mechanical device such as a clip.
Zur Realisierung des vorgenannten Verfahrens erhält die aus EP 0 560 356 A2 bekannte Schreibunterlage seitlich angeordnete Kraftsensoren. Es ist vorgesehen, die unter der Platte angebrachten Kraftsensoren selber mit einem weiteren Satz rechtwinklig zur Haupt wirkrichtung wirkenden Dehnungsmeßstreifen auszurüsten.To implement the aforementioned method, the method known from EP 0 560 356 A2 Force pads on the side of the desk. It is provided that under the plate attached force sensors themselves with another set perpendicular to the main to equip the direction of the strain gauge.
Weiterhin ist vorgesehen, die Oberfläche der den Schreibdruck aufnehmenden Platte mit ei nem weichen Material zu versehen. Der etwas in das Material eindringende Schreibstift übt über die Platte einen stärkeren Druck auf die seitlichen Kraftaufnehmer aus und verbessert somit die Meßergebnisse.It is further provided that the surface of the plate which receives the writing pressure has an egg a soft material. The pen that penetrates something into the material exercises exerted greater pressure on the lateral force transducers via the plate and improved hence the measurement results.
Das Ausführungsbeispiel zeigt eine Vorrichtung des in den Patentansprüchen beschriebe nen Verfahrens. Die seitlich wirkende Kraft des Schreibdruckes wird über die weiche Ober fläche (4) der Platte (3) über den Krafteinleitungspunkt (5) in die Wägezelle oder Kraftauf nehmer (1) eingeleitet. Die unterhalb der Schreibplatte angeordneten Wägezellen oder Kraftaufnehmer (2) dienen der Erfassung der direkt in die Platte geleiteten Schreibdrücke.The embodiment shows a device of the method described in the claims. The lateral force of the writing pressure is introduced via the soft upper surface ( 4 ) of the plate ( 3 ) via the force introduction point ( 5 ) into the load cell or load cell ( 1 ). The load cells or force transducers ( 2 ) located below the writing plate are used to record the writing pressures that are directed directly into the plate.
