Abstract

An apparatus for data transfer with a portable electronic card, for example a payment card or a credit card. It comprises a housing into which a card is introduced. When the card is introduced, a hook is taken along, which is connected to a carriage, which carries compression springs in the form of laminations moulded from one piece with the carriage and which press a flexible insulating foil against the card when due to the introduction of the card the carriage is lowered to the latter by guiding means. The part of the film which is pressed against the card carries metallic contact elements connected through conductive leads to another part of the same foil, which part carries the electronic elements which ensure data processing.

Claims

1. Apparatus for receiving a portable electronic card which includes at least one integrated circuit with a memory and at least one internal contact element coupled with the memory, the apparatus comprising:

a. a housing defining an opening for introducing the card;

b. a slide within the housing, the slide serving as an intermediary for establishing an electrical connection between the card and a circuit outside the card;

c. a slope within the housing, the slope being disposed so that the slide is taken along the slope by insertion of the card;

d. at least one spring carried by the slide; and

e. a flexible insulating foil, carried by the spring, which flexible insulating foil carries at least one external contact element, so that the at least one spring presses the at least one external contact against the at least one internal contact element, after the card is inserted, to establish data transfer between the circuit outside the card and the memory of the card, the same at least one spring being biased between the slide and the flexible insulating foil during said data transfer.

2. The apparatus of claim 1 wherein the flexible insulating foil:

comprises a part which is fixed to the housing, is printed, and carries essential components of the circuit outside the card.

3. The apparatus of claim 2 further comprises means for coupling to a control keyboard having metallized flexible foils with a spacer foil therebetween, the coupling means comprising the fixed part which comprises at least one of the foils of the keyboard.

4. The apparatus of claim 1 wherein the at least one spring and the slide are formed from one piece.

5. The apparatus of claim 4 wherein the at least one spring and the slide are made of molded plastic.

6. The apparatus of claim 1 wherein the at least one spring comprises means for fixing the flexible insulating foil.

7. The apparatus of claim 1 wherein:

a. the housing comprises one of;

a plurality of pins and a plurality of slots; and

b. the slide comprises the other of;

the plurality of pins and the plurality of slots, the pins and slots cooperating with each other to ensure translatory movement of the slide with respect to the housing; and

c. the apparatus further comprises an elastic hook for ensuring that the slide is taken along by the card.

8. The apparatus of claim 7 wherein the slide and the elastic hook are formed from a single piece.

9. An apparatus adapted to receive a portable electronic card comprising a housing provided with an opening for introducing the card, said card being provided with at least one integrated circuit with a memory with which a data transfer is established after insertion of the card in the housing by means of at least one external contact element in the housing being pressed against at least one internal contact element of the card, said housing being provided with a slide which is taken along a slope by insertion of the card and serves as an intermediary for establishing an electrical connection between the card and a circuit outside the card during data processing, said slide carrying at least one spring pressing said external contact element against said internal contact element, wherein the improvement comprises that said spring carries a flexible insulating foil which is provided with said external contact, said spring being biased between said slide and said flexible insulating foil during said data transfer.

10. The apparatus of claim 9 wherein:

a. the housing comprises one of;

a plurality of pins and a plurality of slots; and

b. the slide comprises the other of;

the plurality of pins and the plurality of slots, the pins and slots cooperating with each other to ensure translatory movement of the slide with respect to the housing; and

c. the apparatus further comprises an elastic hook for ensuring that the slide is taken along by the card.

11. An apparatus as claimed in claim 9, wherein the flexible insulating foil:

comprises a part which is fixed to the housing, is printed, and carries essential components of the circuit outside the card.

12. An apparatus as claimed in claim 11, wherein

the fixed part of the flexible insulating foil is at least one of the foils of a control keyboard of the apparatus, which keyboard is of the type having metallized flexible foils with a spacer foil between them.

13. An apparatus as claimed in claim 9 wherein the at least one spring and the

slide are formed from one piece.

14. An apparatus as claimed in claim 13, wherein the slide and the at least one spring are made of moulded plastic material.

15. An apparatus as claimed in claim 9 wherein the at least one spring is provided with means for fixing the flexible insulating foil.

16. An apparatus as claimed in claim 10 wherein the elastic hook and the movable part are formed from one piece.
