Description

Schnittstellenvorrichtung für Chipkarten Interface device for chip cards
Die Erfindung betrifft eine Scrmittstellenvorrichtung für Chipkarten mit einem Gehäuse, das in einen Steckplatz für PCMCIA-Karten eingeschoben werden kann, wobei das Gehäuse eine Vorderseite mit einem daran angrenzenden vorderenThe invention relates to a Scrmittstellevorrichtung for chip cards with a housing that can be inserted into a slot for PCMCIA cards, the housing having a front with an adjacent front
Gehäuseabschnitt, der nicht in den Steckplatz eingeschoben wird, und einenSection of the housing that is not inserted into the slot and one
Einführschlitz für eine Chipkarte aufweist.Has insertion slot for a chip card.
Bei solchen Schnittstellenvorrichtungen, die beispielsweise als Chipkarten- Lesegerät oder -Lese/Schreibgerät ausgebildet sein können, ist der Eiriführschlitz für die Chipkarte an der Vorderseite des Gehäuseabschnitts gebildet, der im eingeschobenen Zustand der Schnittstellenvorrichtung aus dem PCMCIA- Steckplatz herausragt. Die Abmessungen eines PCMCIA-Steckplatzes sind aufgrund der normierten Größe der PCMCIA-Karten vorgegeben, so daß dadurch auch die Größe der Schnittstellenvorrichtung weitgehend festgelegt ist. Aufgrund der eingeschränkten räumlichen Verhältnisse sind die technisch realisierbaren Funktionsmöglichkeiten der Schnittstellenvorrichtung begrenzt. Es besteht jedoch die Möglichkeit, in oder an dem vorderen Gehäuseabschnitt der Schnittstellenvorrichtung, der nicht in den Steckplatz eingeschoben wird und somit in seiner Ausgestaltung keiner Norm entsprechen muß, verschiedene Einrichtungen unterzubringen, die die Funktionalität der Schnittstellenvorrichtung steigern. Insbesondere bei Schnittstellenvorrichtungen, die in die relativ flachen Steckplätze für PCMCIA-Karten des Typs 1 (durchgehende Höhe 3,3|mm) eingeschoben werden sollen, bietet sich so die Möglichkeit, in dem vorderen Gehäuseabschnitt beispielsweise eine Lese/Schreibeinrichtung auszubilden, die in dem flachen, eingeschobenen Gehäuseteil nur schwer unterzubringen ist.In such interface devices, which can be designed, for example, as a chip card reader or reader / writer, the egg guide slot for the chip card is formed on the front of the housing section, which protrudes from the PCMCIA slot when the interface device is inserted. The dimensions of a PCMCIA slot are predetermined on the basis of the standardized size of the PCMCIA cards, so that the size of the interface device is also largely determined thereby. The technically feasible functional possibilities of the interface device are limited due to the restricted spatial conditions. However, there is the possibility of accommodating various devices which increase the functionality of the interface device in or on the front housing section of the interface device which is not inserted into the slot and thus does not have to comply with any standard in its design. In particular, in the case of interface devices which are to be inserted into the relatively flat slots for PCMCIA cards of type 1 (continuous height 3.3 mm), there is the possibility, for example, of forming a read / write device in the front housing section, which in the flat, inserted housing part is difficult to accommodate.
Eine gattungsgemäße Schnittstellenvorrichtung ist aus der EP|0|696|010 bekannt, bei der eine Chipkarte mehr oder weniger tief durch den Einführschlitz auf der Vorderseite des Gehäuses in die Schnittstellenvorrichtung eingeführt wird. Nachteilig ist bei dieser Vorrichtung allerdings, daß in dem vorderen Gehäuseabschnitt durch die Ausbildung des Einführschlitzes für die Chipkarte relativ viel Platz verlorengeht, der anderweitig genutzt werden könnte. Außerdem ist es prinzipiell schwierig, in dem durch den Schlitz zweigeteilten Kragen bestimmte Einrichtungen zu verwirklichen. Schließlich kann eine nicht vollständig in das Gehäuse eingeführte Chipkarte, die aus dem vorderen Gehäuseabschnitt herausragt, als störend empfunden werden.A generic interface device is known from EP | 0 | 696 | 010, in which a chip card is inserted more or less deeply into the interface device through the insertion slot on the front of the housing. The disadvantage of this device, however, is that in the front Housing section through the formation of the insertion slot for the chip card relatively much space is lost, which could be used otherwise. In addition, it is in principle difficult to implement certain devices in the collar, which is divided into two by the slot. Finally, a chip card that is not fully inserted into the housing and protrudes from the front housing section can be perceived as disturbing.
Die Erfindung schafft eine Schnittstellenvorrichtung für Chipkarten, bei der das Volumen des vorderen Gehäuseabschnitts der Schnittstellenvorrichtung besser für funktionelle Einrichtungen genutzt werden kann, ohne daß die emgeführte Chipkarte aus dem Gehäuse herausragt. Gemäß der Erfindung ist vorgesehen, daß der Einführschlitz auf der der Vorderseite entgegengesetzten Seite des vorderen Gehäuseabschnitts ausgebildet ist. Die Erfindung geht von der Erkenntnis aus, daß eine Chipkarte nicht notwendigerweise von vorne in die Schrüttstellenvorrichtung eingeführt werden muß. Bisher wurde dies als unabdingbar angesehen, da nur auf diese Weise eine Chipkarte in eine Schnittstellenvorrichtung, die bereits in einen PCMCIA-Steckplatz eingeschoben ist, eingeführt werden kann. Bei der erfmdungsgemäßen Schnittstellenvorrichtung ist dagegen vorgesehen, die Karte in entgegengesetzter Richtung, d.h. von hinten in den vorderen Gehäuseabschnitt einzuführen. Dies erfordert zwar, daß die Chipkarte in die Schnittstellenvorrichtung eingeführt sein muß, bevor die Vorrichtung in den zugehörigen Steckplatz eingeschoben wird, jedoch erlaubt es die erfindungsgemäße Anordnung des Einfuhrschlitzes, daß alle vorgenannten, bisher notwendigen und als nachteilig erkannten Einschränkungen bei der Ausbildung des vorderen Gehäuseabschnitts der Schnittstellenvorrichtung entfallen können. Somit kann der vordere Gehäuseabschnitt gemäß den entsprechenden Anforderungen der jeweiligen Anwendung frei gestaltet werden.The invention provides an interface device for chip cards in which the volume of the front housing section of the interface device can be better used for functional devices without the chip card emitted protruding from the housing. According to the invention it is provided that the insertion slot is formed on the opposite side of the front housing section from the front. The invention is based on the knowledge that a chip card does not necessarily have to be inserted into the shredding device from the front. So far, this has been regarded as indispensable, since this is the only way to insert a chip card into an interface device that is already inserted into a PCMCIA slot. In the case of the interface device according to the invention, on the other hand, the card is provided in the opposite direction, i.e. insert from the rear into the front housing section. Although this requires that the chip card must be inserted into the interface device before the device is inserted into the associated slot, the arrangement of the insertion slot according to the invention allows all of the aforementioned restrictions, which were previously necessary and recognized as disadvantageous, in the design of the front housing section the interface device can be omitted. The front housing section can thus be freely designed according to the corresponding requirements of the respective application.

Die in den Figuren dargestellte Schnittstellenvorrichtung 10 weist ein längliches Gehäuse 12 mit einer Vorderseite 14 und einer Rückseite 16 auf. Auf der Rückseite 16 des Gehäuses 12 ist eine Vielfach- Kontaktleiste 18 (siehe Fig. 3) vorgesehen. An der Vorderseite 14 des Gehäuses 12 ist ein vorderer Gehäuseabschnitt 20 geformt, der dicker als das restliche Gehäuse 12 ausgebildet und durch eine Stufe 22 von diesem abgegrenzt ist. In der senkrecht zur Längsebene des Gehäuses 12 orientierten Fläche der Stufe 22, die der Vorderseite 14 des Gehäuses 12 entgegengesetzt ist, ist ein Einiührschlitz 24 (siehe Fig. 3) angeordnet. Durch diesen Eirifuhrschlitz 24 kann eine Chipkarte 26 mit einem darauf angebrachten Chip 28 von hinten in den vorderen Gehäuseabschnitt 20 der Schnittstellenvorrichtung 10 eingeführt werden. Zur Erleichterung des Einführens der Chipkarte 20 können in dem vorderen Gehäuseabschnitt 20 zusätzlich Führungs- und Positionierhilfen vorgesehen sein. Außerdem ist der Einschubweg der Chipkarte 26 so begrenzt, daß der Chip 28 der Chipkarte 26 exakt unter entsprechenden Kontakten der Scr-rnttstellenvorrichtung 10 zur Kontaktierung des Chips 28 zu liegen kommt. Mittels einer elastisch biegsamen Bodenplatte 30 des Gehäuses 12 wird der Chip 28 Chipkarte 26 gegen die Kontakte der Schnittstellenvorrichtung 10 gedrückt.The interface device 10 shown in the figures has an elongated housing 12 with a front side 14 and a rear side 16. A multiple contact strip 18 (see FIG. 3) is provided on the rear side 16 of the housing 12. A front housing section 20 is formed on the front side 14 of the housing 12, which is thicker than the rest of the housing 12 and is delimited from it by a step 22. An insertion slot 24 (see FIG. 3) is arranged in the surface of step 22 which is oriented perpendicular to the longitudinal plane of the housing 12 and is opposite the front side 14 of the housing 12. A chip card 26 with a chip 28 attached to it can be inserted from behind into the front housing section 20 of the interface device 10 through this egg slot 24. In order to facilitate the insertion of the chip card 20, additional guide and positioning aids can be provided in the front housing section 20. In addition, the insertion path of the chip card 26 is limited so that the chip 28 of the chip card 26 comes to lie exactly under corresponding contacts of the scrting device 10 for contacting the chip 28. The chip 28 chip card 26 is pressed against the contacts of the interface device 10 by means of an elastically flexible base plate 30 of the housing 12.
Die Abmessungen des Gehäuses 12 sind so gewählt, daß es in einen Steckplatz für genormte PCMCIA-Karten, beispielsweise eines tragbaren Computers, eingeschoben werden kann. Bei der dargestellten Ausführungsform beträgt die Länge 1 des Gehäuses 12 ohne den vorderen Gehäuseabschnitt 20, d.h. von der Rückseite 16 bis zur Stufe 22, 85 6!mm, was der Standardlänge einer PCMCIA- Karte entspricht. Das Gehäuse 12 der Schnittstellenvorrichtung 10 wird mit eingelegter Chipkarte 26 mit der Rückseite 16 bis zur Kante 22 in den (nicht gezeigten) PCMCIA-Steckplatz eingeschoben. Über die Kontaktleiste 18 des Gehäuses 12 ist die Schnittstellenvorrichtung 10 dann mit dem Computer verbunden. Der dicker als das restliche Gehäuse 12 ausgebildete vordere Gehäuseabschnitt 20 ragt aus dem Steckplatz heraus.The dimensions of the housing 12 are chosen so that it can be inserted into a slot for standardized PCMCIA cards, for example a portable computer. In the embodiment shown, the length 1 of the housing 12 without the front housing section 20, ie from the rear 16 to the step 22, is 85 mm, which corresponds to the standard length of a PCMCIA card. The housing 12 of the interface device 10 is with inserted chip card 26 with the back 16 up to the edge 22 in the (not shown) PCMCIA slot. The interface device 10 is then connected to the computer via the contact strip 18 of the housing 12. The front housing section 20, which is thicker than the rest of the housing 12, protrudes from the slot.
Der vordere Gehäuseabschnitt 20 beherbergt funktioneile Einrichtungen der Schnittstellenvorrichtung 10. Beispielsweise kann dort eine Lese/Schreibvorrichtung mit einem Kontaktfeld zur Kontaktierung der Chipkarte 26 vorgesehen sein. Es ist auch möglich, gemäß der dargestellten Ausfuhrungsform eine Sende/Empfangseinrichtung mit einer an dem vorderen Gehäuseabschnitt 20 angeordneten Antenne 32 zu verwirklichen, mit der beispielsweise eine Verbindung zu einem Mobiltelefon hergestellt werden kann. The front housing section 20 houses functional devices of the interface device 10. For example, a read / write device with a contact field for contacting the chip card 26 can be provided there. It is also possible, according to the embodiment shown, to implement a transmitting / receiving device with an antenna 32 arranged on the front housing section 20, with which an connection to a mobile telephone can be established, for example.
