    Abstract: A scanning apparatus for a chip card has a fixedly arranged first set of contacts. A drawer is displaceable in level relative to the contacts and, into which drawer, in the position in which it is withdrawn from the apparatus, the chip card can be inserted into an accommodation space within the drawer. The card is located at a distance spaced from the level of the set of contacts. Guides cooperate on both sides with the drawer and cause the drawer to displace stepwise upon insertion of the drawer into the apparatus in the region of the set of contacts towards the level of the first set of contacts.
