Abstract
Abstract A contact frame for an IC card reader including, in particular, guide means for guiding or positioning the card, together with contact elements for providing electrical connection with conducting pads on the IC card via which circuits are established to the apparatus including the IC card reader, the contact frame being characterized by the fact that it comprises an inner frame (7) of insulating material molded over the contact elements (4) for providing electrical connection to the IC card, and two extensions (17, 18) extending the substance of the inner frame (7) sideways towards the side edges of the card and beyond said edges, each of said two extensions carrying means (6, 19, 20) for defining the positions of two card-guiding slideways (21, 22).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
178 words
A contact frame for contact with an IC card of an IC card reader, said IC card having opposite side edges, said contact frame comprising, in particular, guide means for guiding or positioning the IC card, together with contact elements for providing electrical connection with the conducting pads on the IC card via which circuits are established to the apparatus including the IC card reader, the improvement wherein the contact frame comprises an inner frame portion of insulating material molded over the contact elements for providing electrical connection to the IC card, said inner frame portion being a hollow structure comprising at least two side members and two beams supported between the two side members, said two beams each carrying a contact set, with said contact sets mainly extending from one beam in the direction of the other, and two extensions extending said inner frame portion sideways towards said side edges of the card and beyond said side edges, each of said two extensions carrying means for defining the portion of a corresponding one of two card-guiding slideways.
Claim 2
Dependent Claim
178 words
A contact frame for contact with an IC card of an IC card reader, said IC card having opposite side edges, said contact frame comprising, in particular, guide means for guiding or positioning the IC card, together with contact elements for providing electrical connection with the conducting pads on the IC card via which circuits are established to the apparatus including the IC card reader, the improvement wherein the contact frame comprises an inner frame portion of insulating material molded over the contact elements for providing electrical connection to the IC card, said inner frame portion being a hollow structure comprising at least two side members and two beams supported between the two side members, said two beams each carrying a contact set, with said contact sets mainly extending from one beam in the direction of the other, and two extensions extending said inner frame portion sideways towards said side edges of the card and beyond said side edges, each of said two extensions carrying means for defining the portion of a corresponding one of two card-guiding slideways.
Claim 3
Dependent Claim
63 words
A contact frame according to claim 1, wherein said contact frame carries a moving contact blade and a fixed contact blade of an end-of-stroke contact disposed on the front edge of said frame which is not reached by said card, except for a portion of the moving blade against which the card comes into abutment when it reaches the end of its stroke.
Claim 4
Dependent Claim
16 words
A contact frame according to claim 1, wherein the extensions are perforated, at least in part.
Claim 5
Dependent Claim
22 words
A contact frame according to claim 1, wherein the slideways are made, at least in part, from the substance of said frame.
Claim 6
Dependent Claim
23 words
A contact frame according to claim 1, wherein each slideway is constituted, at least in part, by a piece added to each extension.
Claim 7
Dependent Claim
28 words
A contact frame according to claim 5, wherein said add-on pieces are integrally formed with a part covering said frame and constituting a lid which is assembled therewith.
Claim 8
Dependent Claim
18 words
A contact frame according to claim 5, wherein the slideways are totally constituted by an add-on lid-forming part.
Claim 9
Dependent Claim
