DESCRIPTION:

BRIEF SUMMARY
The invention relates to a chip card reader which consists of a mobile reading module and a sleeve which can be inserted into an accommodation slot of a computer and into which the reading module can be inserted.
Chip card reading modules are known from the prior, not pre-published, DE 196 04 031.0-53. They are used as interfaces between a computer and a chip card and can be inserted into a corresponding accommodation slot of a computer. Therefore, by the use of such reading modules a direct data transfer from a computer to a chip card and/or from a chip card to a computer is made possible.
Chip cards can store data for a variety of purposes, such as for making telephone calls, for control applications, account keeping, security checks, etc. The chip cards normally have the usual credit card format and can be read by chip card readers of different types. In this context, separate chip card readers are also known which are connected to a computer in order to transfer data from the chip card to the computer. Such separately arranged devices, however, require a connecting cable and a connecting plug and are unwieldy because of their size, and are susceptible to interference on account of their unprotected plug and socket connectors.
The chip card reading module known from DE 196 04 031.0-53 solves the problem of providing a small and handy interface between a chip card and a computer in which the reliability of the data transfer with the computer is increased.
The object of the present invention is to make the chip card reading module even smaller and lighter.
In accordance with the invention, this object is achieved by a division of the reader into a mobile reading module and a sleeve into which the reading module can be inserted and which can remain inserted in the accommodation slot of the computer.
Preferred embodiments of the invention are the subject of the sub-claims.
In the chip card reading module in accordance with the invention it is thus made possible to divide the chip card reading module known from DE 196 04 031.0-53 into two units, the chip card reading module in accordance with the invention constituting the first unit and the sleeve of the chip card reading module in accordance with the invention constituting the second unit. The second unit is embodied in such a way that it can remain permanently inserted in the accommodation port of a computer. Because of this it becomes possible to make the chip card reading module in accordance with the invention, which as such is not inserted directly into the computer, but into the second unit, even smaller and lighter than in the prior art.
The chip card reading module in accordance with the invention enables new services and processes to be performed by means of a particularly light and space-saving chip card module, in particular data transmission, such as electronic cash transfer, access security, transfer of medical data, or the transfer of computer files from a computer to a chip card or vice versa. Furthermore, the chip card reading module in accordance with the invention in the form of preferred embodiments offers the advantage that it can be used both as a contacting chip card reading module (ICC, integrated circuit card) and as a contactless chip card reading module (CICC, contactless integrated circuit card).
According to a preferred embodiment of the chip card reading module in accordance with the invention, at the end of the front area of the channel for accommodating the chip card, two lugs, triangular in cross-section, are arranged, the inward pointing surfaces of each of which come to abut against the rounded corner sides of the inserted chip card. By means of these lugs a lateral fixing of the chip card in the channel accommodating the chip card is achieved, so that the chip card, when abutting against these lugs, remains immovable within the channel accommodating the chip card.
In accordance with an important embodiment of the chip card reading module according to the invention, the sleeve forming the counterpart of the chip card readi
