Abstract
Abstract A card reader in which a data area on a card is scanned by movement of a reading head across a data area, the reading head being carried by a movable carriage and coupled to the carriage by a plurality of parallel, resiliently flexible cantilever members extending between the carriage and the reading head and enabling displacement of the reading head relative to the carriage in a direction normal to the data area to compensate for variations in the spacing between the data area and the fixed path of travel of the carriage while maintaining proper orientation of the reading head relative to the data area without introducing effective changes of reading speed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
In a card reader in which a data area located upon a card is scanned by movement of a reading head across the data area, a reading head mounting arrangement comprising: a carriage movable along a fixed path of travel generally parallel to the data area; a plurality of elongate members projecting from the carriage parallel to the data area and spaced therefrom, each member having one end affixed to the carriage and an opposite end remote from the carriage, each member being located at a different vertex of a polygon lying in a plane generally perpendicular to the data area and being movable about said one end in the direction perpendicular to the data area and parallel to said plane; and means coupling the reading head to said members at the opposite ends thereof such that the reading head is in proper orientation relative to the data area for scanning the data area and is displaceable relative to the carriage in said direction by movement of said members in said direction while being confined to said proper orientation during such displacement.
Claim 2
Dependent Claim
182 words
In a card reader in which a data area located upon a card is scanned by movement of a reading head across the data area, a reading head mounting arrangement comprising: a carriage movable along a fixed path of travel generally parallel to the data area; a plurality of elongate members projecting from the carriage parallel to the data area and spaced therefrom, each member having one end affixed to the carriage and an opposite end remote from the carriage, each member being located at a different vertex of a polygon lying in a plane generally perpendicular to the data area and being movable about said one end in the direction perpendicular to the data area and parallel to said plane; and means coupling the reading head to said members at the opposite ends thereof such that the reading head is in proper orientation relative to the data area for scanning the data area and is displaceable relative to the carriage in said direction by movement of said members in said direction while being confined to said proper orientation during such displacement.
Claim 3
Dependent Claim
16 words
The invention of claim 1 including means resiliently biasing the reading head toward the data area.
Claim 4
Dependent Claim
56 words
The invention oF claim 1 wherein: said data area lies nominally in a plane; the path of travel of the carriage is parallel to the plane of the data area; the members extend parallel to one another; and the direction of displacement of the reading head is perpendicular to the path of travel of the carriage.
Claim 5
Dependent Claim
46 words
The invention of claim 3 wherein each member is a resiliently flexible cantilever with the one end thereof secured to the carriage and the opposite end thereof free to move in the direction perpendicular to the data area and parallel to the plane of said polygon.
Claim 6
Dependent Claim
16 words
The invention of claim 4 including means resiliently biasing the reading head toward the data area.
Claim 7
Dependent Claim
34 words
The invention of claim 5 wherein said biasing means include at least one spring between the carriage and the reading head for urging the reading head relative to the carriage toward the data area.
Claim 8
Dependent Claim
19 words
The invention of claim 4 including four of said members, each located at a different vertex of a rectangle.
Claim 9
Dependent Claim
16 words
The invention of claim 7 including means resiliently biasing the reading head toward the data area.
Claim 10
Dependent Claim
34 words
The invention of claim 8 wherein said biasing means include at least one spring between the carriage and the reading head for urging the reading head relative to the carriage toward the data area.
