Fig. 4b die Ansicht der Tastpitze nach Fig. 4a. FIG. 4b shows the view of the Tastpitze according to Fig. 4a.

Der Stift nach vorliegender Erfindung besteht aus dem Handteil 1 und einer Spitze 2. Die Spitze 2 ist in den Beispielen so ausgeführt, daß in einem speziell geformten Bereich 4 unterschiedliche gestaltete Antennen 5 untergebraucht werden können und in einem weiteren Bereich 3 eine Tastspitze für das Berühren von Touchsreens gebildet ist. Beide Bereiche 4 und 3 können auch ineinander übergehen. Die Antennen 5 sind vorzugsweise durch elektrische Spulen gebildet, die ein magnetisches Feld abstrahlen. Desweiteren enthält der Stift eine Schreib-/Leseelektronik 7 üblicher Art, weshalb diese hier nicht weiter ausgeführt werden braucht, die mit der Antennen 5 über Spulendrähte 6 der Antenne 5 verbunden ist und optional mögliche Zusatzelemente 9 wie Batterie, Anschlußstecker oder Kabel oder Datenfunkbausteine, ebenfalls üblicher Art. The pen according to the present invention consists of the hand part 1 and a tip 2 . The tip 2 is designed in the examples so that differently designed antennas 5 can be used in a specially shaped area 4 and in a further area 3 a probe tip is formed for touching touch screens. Both areas 4 and 3 can also merge. The antennas 5 are preferably formed by electrical coils that emit a magnetic field. Furthermore, the pen contains a read / write electronics 7 of the usual type, which is why it does not need to be described here, which is connected to the antenna 5 via coil wires 6 of the antenna 5 and optionally possible additional elements 9 such as battery, connector or cable or data radio modules, also usual type.

Entscheidend ist die spezielle Ausführung und Geometrie der Spitze und Antenne. What is decisive is the special design and geometry of the tip and Antenna.

Fig. 2 zeigt eine erste axialsymmetrische Ausführung der Stiftspitze nebst Gestaltung einer ersten Schreib-Lese-Antenne. Eingesetzt wird in diesem Beispiel ein ferromagnetischer Kern 11, der stabförmig ausgebildet ist, um den eine Spule 10 gewickelt ist, wobei der Spitzenbereich 3 allseitig zentrisch verjüngt zulaufend und verrundet ausgebildet ist. Fig. 2 shows a first axially symmetrical design of the pen tip together with the design of a first read / write antenna. In this example, a ferromagnetic core 11 is used , which is designed in the form of a rod, around which a coil 10 is wound, the tip region 3 tapering on all sides in a tapering and rounded manner.

Bei ausreichender Kopplung zwischen Antenne 5 und einem in den Beispielen nicht näher dargestellten üblichen Transponder kann das Kernmaterial 11 im Einzelfall u. U. entfallen, was auch für die nachfolgenden Beispiele gilt, jedoch keine bevorzugte Ausführung darstellt. With sufficient coupling between antenna 5 and a conventional transponder, not shown in the examples, the core material 11 can in individual cases and It may not apply, which also applies to the following examples, but is not a preferred embodiment.

Fig. 3a zeigt eine zweite Ausführungsmöglichkeit der Stiftspitze nebst Gestaltung einer zweiten Schreib-Lese-Antenne mit einem U-Kern 12, die insbesondere für Glastransponder und Transponder mit einem Schalenkern geeignet ist. Dabei weist die Stiftspitze eine längserstreckte ovalförmige Gestaltung auf, wie die in Fig. 3b dargestellte Ansicht der Tastpitze zeigt. Bei dem ferromagnetisch, U-förmig ausgebildeten Kern 12 ist in diesem Beispiel die Spule 10 um den die beiden parallel verlaufenden Scheitel und diese senkrecht verbindenden Kernbereich gewickelt, wobei der Spitzenbereich (3) beidseitig in einer Dimension konisch verjüngt zulaufend ausgebildet ist und im Tastspitzenkopf eine Abschrägung 31 aufweist. Fig. 3a shows a second possible embodiment of the pen tip design together with a second read-write antenna having a U-core 12 that is suitable in particular for glass transponder and transponder having a shell core. The pen tip has an elongated oval shape, as the view of the probe tip shown in FIG. 3b shows. In the case of the ferromagnetic, U-shaped core 12 , in this example the coil 10 is wound around the core region that connects the two parallel vertices and the core region that connects them vertically, the tip region ( 3 ) being tapered in one dimension on both sides and one in the probe tip head Has chamfer 31 .

Nach Fig. 4a ist ein Schalenkern 13 eingesetzt, in den die Spule 10 eingelegt ist, wobei der Spitzenbereich 3 azentrisch verjüngt zulaufend und im Tastspitzenkopf mit einer Abschrägung 31 versehen ist. Damit bietet die Spitze Platz für den asymmetrischen Schalenkern 12 und erreicht eine punktuelle Geometrie. Die Spitzen in Fig. 3 und 4 werden beim Tasten auf Touchscreens optimal in senkrechter Lage und bei Verwendung mit Transpondern in einer Neigung von 10° bis 45° zum Gegenstand in oder auf dem sich der Transponder befindet benutzt. Die Fig. 4b zeigen eine Ansicht der Spitze von unten. According to FIG. 4a, a shell core 13 is inserted, in which the coil 10 is inserted, the tip region 3 tapering acentrically and being provided with a bevel 31 in the probe tip head. The tip thus offers space for the asymmetrical shell core 12 and achieves a specific geometry. The tips in FIGS. 3 and 4 are optimally used when touching on touchscreens in a vertical position and when used with transponders at an inclination of 10 ° to 45 ° to the object in or on which the transponder is located. FIG. 4b show a view of the top from the bottom.

Bei allen Anordnungen sollte der maximale Durchmesser der Spitze am Handteil nicht größer sein als ca. 15 mm. In all arrangements, the maximum diameter of the tip should be at Handpiece should not be larger than approx. 15 mm.

Auch bei den Ausführungen nach den Fig. 3 und 4 kann die Abschrägung 31 im Bereich des kleinsten Krümmungsradius 32 verrundet ausgeführt sein. Also in the embodiments according to FIGS. 3 and 4, the chamfer 31 may be designed rounded in the region of the smallest radius of curvature 32nd

Die Spitzenform sollte in jedem der Ausführungsbeispiele so gestaltet sein, daß die Größe der Spitze möglichst kleine Tastfelder auf dem Touchscreen eindeutig berühren läßt. Die Berührungsfläche sollte kleiner als 1 mm2 sein und den Sichtbereich des Benutzers bei Verwendung als Tastpen oder als Transponderlesestift für kleine Transponder minimal eingeschränkt und eine ergonomische Handhabung zuläßt, wobei der erreichbare Kommunikationsabstand zwischen Stift und Transponder maximal bleiben soll. In each of the exemplary embodiments, the tip shape should be designed in such a way that the size of the tip can clearly touch the smallest possible touch fields on the touchscreen. The contact area should be less than 1 mm 2 and the view of the user when used as a stylus or as a transponder reading pen for small transponders should be minimal and ergonomic handling should be allowed, while the achievable communication distance between pen and transponder should remain at a maximum.

Die Vorteile vorliegender Erfindung bestehen in einer kleinen und kompakte Bauform, die einen universellen Einsatz ermöglicht. Bei Anwendung von PDAs muß der Anwender nicht zwei separate Geräte, wie nach dem Stand der Technik üblich, wie Touchpen und Readerpen, benutzen. Bezugszeichenliste 1 Handteil
