Abstract
Abstract A chip card reader includes a frame, reading contact elements, and an end position switch which includes two switching contact elements arranged to either close or open upon reaching of the reading position by a chip card. The contact elements are identical in both the arrangement in which the elements open to indicate reaching of the reading position by the chip card and the arrangement in which the elements close to indicate reaching of the reading position by the chip card. The frames may also be identical in the opener arrangement and the closer arrangement.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
Chip card reader comprising a frame in which reading contact elements and an end position switch are provided, said end position switch comprising means including two switching contact elements which contact each other in a contact area for indicating upon opening the reaching of a reading position by a chip card, wherein one of said switching contact elements is a movable switching contact element and the other of said switching contact elements is a static switching contact element, wherein both said switching contact elements comprise locking means adapted to be locked in the frame for mounting the switching contact elements in the frame, and wherein both switching contact elements are biased into rest positions, wherein, in the contact area of said movable and said static switching contact elements, cusps are formed, and wherein said cusps are in the form of cylinders having cylinder axes which are substantially transverse to each other.
Claim 2
Dependent Claim
151 words
Chip card reader comprising a frame in which reading contact elements and an end position switch are provided, said end position switch comprising means including two switching contact elements which contact each other in a contact area for indicating upon opening the reaching of a reading position by a chip card, wherein one of said switching contact elements is a movable switching contact element and the other of said switching contact elements is a static switching contact element, wherein both said switching contact elements comprise locking means adapted to be locked in the frame for mounting the switching contact elements in the frame, and wherein both switching contact elements are biased into rest positions, wherein, in the contact area of said movable and said static switching contact elements, cusps are formed, and wherein said cusps are in the form of cylinders having cylinder axes which are substantially transverse to each other.
Claim 3
Dependent Claim
38 words
Chip card reader according to claim 1, wherein the stationary switching contact element is biased against an abutment member formed by a frame and wherein the movable switching contact element is biased against the static switching contact element.
Claim 4
Dependent Claim
41 words
Chip card reader according to claim 2, wherein a switching portion of the movable switching contact element is fork-like, forming a contact arm and spaced therefrom a second arm which in turn forms an abutment angle for forming a card abutment.
Claim 5
Dependent Claim
41 words
Chip card reader according to claim 1, wherein a switching portion of the movable switching contact element is fork-like, forming a contact arm and spaced therefrom a second arm which in turn forms an abutment angle for forming a card abutment.
Claim 6
Dependent Claim
30 words
Chip card reader according to claim 1, wherein said switching contact elements are substantially collinear and extend in opposite directions from a contact area between the two contact element springs.
Claim 7
Dependent Claim
150 words
Chip card reader comprising a frame in which reading contact elements and an endposition switch are provided, said end position switch comprising means including two switching contact elements which contact each other in a contact area for indicating upon closing the reaching of a reading position by a chip card, wherein one of said switching contact elements is a movable switching contact element and the other of said switching contact elements is a static switching contact element, wherein both said switching contact elements comprise locking means adapted to be locked in the frame for mounting the switching contact elements in the frame, and wherein both switching contact elements are biased into rest positions. wherein, in the contact area of said movable and said static switching contact elements, cusps are formed, and wherein said cusps are in the form of cylinders having cylinder axes which are substantially transverse to each other.
Claim 8
Dependent Claim
150 words
Chip card reader comprising a frame in which reading contact elements and an endposition switch are provided, said end position switch comprising means including two switching contact elements which contact each other in a contact area for indicating upon closing the reaching of a reading position by a chip card, wherein one of said switching contact elements is a movable switching contact element and the other of said switching contact elements is a static switching contact element, wherein both said switching contact elements comprise locking means adapted to be locked in the frame for mounting the switching contact elements in the frame, and wherein both switching contact elements are biased into rest positions. wherein, in the contact area of said movable and said static switching contact elements, cusps are formed, and wherein said cusps are in the form of cylinders having cylinder axes which are substantially transverse to each other.
Claim 9
Dependent Claim
39 words
Chip card reader according to claim 6, wherein the movable switching contact element is biased against an abutment member formed by the frame, and wherein the static switching contact element is biased against a pin formed by the frame.
Claim 10
Dependent Claim
41 words
Chip card reader according to claim 6, wherein a switching portion of the movable switching contact element is fork-like, forming a contact arm and spaced therefrom a second arm which in turn forms an abutment angle for forming a card abutment.
