Abstract
Abstract A code card reader having a contact which can be moved vertically relative to a code card so as to be brought into contact with the code card at the contact-making area of an integrated circuit of the code card. In a preferred embodiment, vertical movement of the contact carrier toward the code card may be provided in response to horizontal movement of the code card by means of a kinematically rigid gear mechanism.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
78 words
A code card reader comprising: a contact for contacting a contact-making area of an integrated circuit of a code card; means for varying vertical distance between said contact and a code card received by said code card reader comprising a contact carrier and at least two wheels mounted eccentrically on the contact carrier for varying the vertical distance between said contact carrier and said code card; and a track providing a path of rolling motion of said wheels.
Claim 2
Dependent Claim
78 words
A code card reader comprising: a contact for contacting a contact-making area of an integrated circuit of a code card; means for varying vertical distance between said contact and a code card received by said code card reader comprising a contact carrier and at least two wheels mounted eccentrically on the contact carrier for varying the vertical distance between said contact carrier and said code card; and a track providing a path of rolling motion of said wheels.
Claim 3
Dependent Claim
27 words
The code card reader of claim 1, wherein said at least two wheels comprise gearwheels and wherein said track comprises teeth for engaging teeth of said gearwheels.
Claim 4
Dependent Claim
24 words
The code card reader of claim 2, wherein said contact carrier further comprises a stop for engaging a forward edge of said code card.
Claim 5
Dependent Claim
15 words
The code card reader of claim 3, wherein said stop comprises at least one roller.
Claim 6
Dependent Claim
16 words
The code card reader of claim 1, wherein a trajectory of said contact describes an epicycloid.
Claim 7
Independent Claim
44 words
A method for operating a code card reader comprising the steps of: receiving a code card; and moving a contact of said code card reader toward a contact-making area of said code card alone an epicycloid trajectory to make contact with said contact-making area.
Claim 8
Independent Claim
44 words
A method for operating a code card reader comprising the steps of: receiving a code card; and moving a contact of said code card reader toward a contact-making area of said code card alone an epicycloid trajectory to make contact with said contact-making area.
Claim 9
Dependent Claim
35 words
The method of claim 6, further comprising the steps of: reading said code card; and transporting said code card in the direction of motion of said code card during said receiving of said code card.
Claim 10
Dependent Claim
76 words
A code card reader comprising: a contact for contacting a contact-making surface of an integrated circuit of a code card; and a mechanism for varying a relative distance between said contact and a code card received by said code card reader in a direction substantially perpendicular to said contact making surface as a function of distance of movement of said code card in a direction of insertion of said code card and along an epicycloid trajectory.
Claim 11
Dependent Claim
76 words
A code card reader comprising: a contact for contacting a contact-making surface of an integrated circuit of a code card; and a mechanism for varying a relative distance between said contact and a code card received by said code card reader in a direction substantially perpendicular to said contact making surface as a function of distance of movement of said code card in a direction of insertion of said code card and along an epicycloid trajectory.
Claim 12
Dependent Claim
14 words
The code card reader of claim 8 wherein said mechanism includes eccentrically mounted wheels.
Claim 13
Dependent Claim
12 words
The code card reader of claim 9 wherein said wheels are gearwheels.
