Abstract

The aim of the invention is to integrate a brush (8) for scraping off dust or dirt into an insertion slit (5.1) and/or a plug-in slit (3.1) of a card reader (5, 3). Said brush (8) is preferably applied to the inner wall (1.1.2) of the housing of the card reader (3, 5), such that the bristles (8.1) of the brush (8) cover the insertion (5.1) and/or plug-in slit (3.1). The bristles (8.1) of the brush (8) can be fixed to a self-adhesive strip that is then stuck at least in the region of the insertion slit (5.1) and/or the plug-in slit (3.1) of the card reader (5, 3), and covers the reading head (9) beneath. Alternatively, the brush (8) can protrude from the inside or fixed during the injection moulding. The bristles (8,1) consist of very fine fibres that are flexible under pressure, in such a way that the insertion/plug-in of the card (7) does not unfavourably influence the functionality of the card reader (5, 3).

Der Erfindung stellt sich die Aufgabe, einen Schutz für einen Kartenleser insbesondere für eine POS- Tastatur aufzuzeigen, durch den das Eindringen zumindest von Schmutz und Staub in den Kartenleser verhindert wird.The object of the invention is to provide protection for a card reader, in particular for a POS keyboard, by which at least dirt and dust are prevented from penetrating into the card reader.
Gelöst wird die Aufgabe durch die Merkmaie des Patentanspruchs 1.The task is solved by the features of claim 1.
Die Erfindung greift die Idee auf, eine Staub oder Dreck abstreifenden Bürste im Durchzugs- und / oder Einsteckschlitz eines Kartenlesers einzubinden. Die Bürste wird dabei vorzugsweise an der Gehäuseinnenwand des Kartenlesers angebracht, so dass Borsten der Bürste den Durchzugs- / Einsteckschlitz abdecken. Die Borsten der Bürste können dabei auf einem selbstklebendem Band fixiert sein, welches dann zumindest im Bereich des Durchzugsschlitzes / des Einsteckschlitzes des Kartenlesers aufgeklebt ist und den darunter befindlichen Lesekopf schützt. Alternativ besteht auch die Möglichkeit, die Bürste im Gehäuse des Kartenlesers im Bereich des Leserkopfs von innen zu verstämmen oder während des Spritzgießens zu fixieren. Die Borsten bestehen aus sehr feinen, Druck nachgiebigen Fasern, so dass ein Durchziehen / Einstecken der Karte die Funktionalität des Kartenlesers nicht nachteilig beeinflusst.The invention picks up on the idea of incorporating a brush wiping away dust or dirt in the pull-through and / or insertion slot of a card reader. The brush is preferably attached to the inside wall of the card reader so that bristles of the brush cover the pull-through / insertion slot. The bristles of the brush can be fixed on a self-adhesive tape, which is then glued on at least in the area of the pull-through slot / insertion slot of the card reader and protects the reading head underneath. As an alternative, there is also the option of tamping the brush in the housing of the card reader in the area of the reader head from the inside or fixing it during injection molding. The bristles consist of very fine, pressure-yielding fibers, so that pulling / inserting the card does not adversely affect the functionality of the card reader.

Fig. 3 den Kartenleser im Schnitt A-A aus Fig. 2.3 shows the card reader in section A-A from FIG. 2.
Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
In Fig. 1 ist eine Tastatur 1 dargestellt, die zumindest ein Tastenfeld 2 sowie einen hier im Tastaturgehäuse 1.1 integrierten Kartenleser 3, 5 aufweist. Der Kartenleser 3 ist in dieser1 shows a keyboard 1 which has at least one keypad 2 and a card reader 3, 5 integrated here in the keyboard housing 1.1. The card reader 3 is in this
Ausführung einen Chipkartenleser, in den eine nicht näher dargestellt Karte senkrecht einge- steckt werden kann (Einsteckschlitz 3.1). Der weitere Kartenleser 5, ein Magnetkartenleser, weist einen Durchzugsschlitz 5.1 für eine Magnetkarte 7 auf (Fig.2). Möglich ist auch ein separater Kartenleser 3, 5 mit einem eigenen Karteniesergehäuse (nicht näher dargestellt).Execution of a chip card reader into which a card, not shown, is inserted vertically. can be inserted (insertion slot 3.1). The further card reader 5, a magnetic card reader, has a pull-through slot 5.1 for a magnetic card 7 (FIG. 2). A separate card reader 3, 5 with its own card reader housing (not shown in more detail) is also possible.
Zumindest im Bereich des Durchzugsschlitzes 5.1 ist vorgesehen, eine feine Bürste 8 mit Borsten 8.1 zu integrieren, um Staub und Dreck vom Kartenleser 3, 5 insbesondere aber vom Leserkopf 9 fernzuhalten.At least in the area of the pull-through slot 5.1, it is provided to integrate a fine brush 8 with bristles 8.1 in order to keep dust and dirt away from the card reader 3, 5, but in particular from the reader head 9.
Wie in Fig. 3 erkennbar, wird die Bürste 8, entweder einseitig oder beidseitig im Bereich des Durchzugsschlitzes 5.1 oberhalb des Kartenlesers 5 mit Leserkopf 9 an der Gehäuseinnenseite 1.1.2 angebracht. Dies kann durch eine Klebverbindung, ein Fixieren beim Spritz- bzw. beim Herstellungsprozess des Gehäuses des Kartenlesers 3, 5 / des Tastaturgehäuses 1.1 oder durch Verstemmen erfolgen. Dabei schliesst(en) die Bürste(n) zumindest mit der zum Kartenleser 5 weisenden Durchzugskante 1.1.1 im Gehäuse 1.1 ab.As can be seen in FIG. 3, the brush 8 is attached either on one side or on both sides in the area of the pull-through slot 5.1 above the card reader 5 with a reader head 9 on the inside of the housing 1.1.2. This can be done by an adhesive connection, a fixation during the injection molding or manufacturing process of the housing of the card reader 3, 5 / the keyboard housing 1.1 or by caulking. The brush (s) ends at least with the pull-through edge 1.1.1 facing the card reader 5 in the housing 1.1.
In der einen Variante des Klebens werden die Bürste(n) 8 von unten gegen die Gehäuseinnenseite 1.1.2 geklebt. Die weichen Borsten 8.1 liegen entweder direkt an der gegenüberliegenden Gehäusekante 1.1.1 an oder, wenn zwei Bürsten 8 verwendet werden, an den gegenüberliegenden Borsten 8.1 leicht aneinander.In one variant of the gluing, the brush (es) 8 are glued from below against the inside of the housing 1.1.2. The soft bristles 8.1 either lie directly on the opposite housing edge 1.1.1 or, if two brushes 8 are used, lightly against one another on the opposite bristles 8.1.
Beim Kalt- oder Warmverstämmen sind am Gehäuse 1.1 an der Gehäuseinnenseite 1.1.2 vorzugsweise nach innen weisende Zapfen (nicht näher dargestellt) vorgesehen, die zumindest in ein Loch in der Bürste 8 eingreifen und damit die Bürste 8 fixieren.During cold or hot stamping, pins (not shown in detail) are preferably provided on the inside of the housing 1.1.2 on the inside of the housing 1.1.2, which engage at least in a hole in the brush 8 and thus fix the brush 8.
Das Einbringen und Befestigen der Bürste(n) 8 während des Spritzvorganges zur Herstellung des Karteniesergehäuses oder des Tastaturgehäuses 1.1 ist ebenfalls durch Fixierung im Werkzeug möglich. Hierbei ist darauf zu achten, dass ein Verkleben der Bürstenfortsätze 8.1 vermieden wird.The introduction and fastening of the brush (s) 8 during the injection molding process for the production of the card reader housing or the keyboard housing 1.1 is also possible by fixation in the tool. It is important to ensure that the brush extensions 8.1 do not stick together.
Die Idee lässt sich auch auf den Kartenleser 3 übertragen. Dabei kann auch hier die Bürste 8 einseitig oder beidseitig vom Einsteckschlitz 3.1 des Chipkartenlesers 3 mittels Kleben, Verstemmen oder Fixierung beim Spritzvorgang vorgesehen sein. The idea can also be transferred to the card reader 3. Here, too, the brush 8 can be provided on one side or on both sides of the insertion slot 3.1 of the chip card reader 3 by means of gluing, caulking or fixing during the spraying process.
