Abstract
Abstract In a card reader of the type having a generally fixed read head or transducer for serially scanning across an encoded portion of an encoded card transported past the read head, by transport mechanism, the mechanism including an energy storing device receiving the card and expending the stored energy to displace the card past the read head, the mechanism further including an acceleration or velocity limiting device coupled to the energy storing device for limiting transport of the card to a constant velocity past the read head.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
228 words
In a card reader transport mechanism, the combination comprising; a base, a transducer mounted above said base and adapted to serially scan across an encoded portion of an encoded card which is transported past said transducer, wherein said transport mechanism is adapted to transport said card serially past said transducer, the improvement comprising: an energy storing mechanism comprising a reeling device which is provided with a reeled strip capable of automatically rewinding in reeled configuration on said reeling device, said energy storing mechanism being responsive to the displacement of said card from a first position to a second position to store energy thereby, said displacement of said card from said first position to said second position creates unreeling of said strip from said reeling device, said energy storing mechanism expending the stored energy at a constant rate to rewind said strip and thereby displace said card from said second position to said first position, thereby transporting said card serially past said transducer, and a throttling device coupled to said energy storing mechanism for controlling the rate at which the stored energy is expended so as to limit displacement of said card to a constant velocity past said transducer, said throttling device being in the form of a fluidic dash-pot opposing the automatically rewinding strip and thereby limiting the rate of rewinding of said strip to a constant rate.
Claim 2
Dependent Claim
228 words
In a card reader transport mechanism, the combination comprising; a base, a transducer mounted above said base and adapted to serially scan across an encoded portion of an encoded card which is transported past said transducer, wherein said transport mechanism is adapted to transport said card serially past said transducer, the improvement comprising: an energy storing mechanism comprising a reeling device which is provided with a reeled strip capable of automatically rewinding in reeled configuration on said reeling device, said energy storing mechanism being responsive to the displacement of said card from a first position to a second position to store energy thereby, said displacement of said card from said first position to said second position creates unreeling of said strip from said reeling device, said energy storing mechanism expending the stored energy at a constant rate to rewind said strip and thereby displace said card from said second position to said first position, thereby transporting said card serially past said transducer, and a throttling device coupled to said energy storing mechanism for controlling the rate at which the stored energy is expended so as to limit displacement of said card to a constant velocity past said transducer, said throttling device being in the form of a fluidic dash-pot opposing the automatically rewinding strip and thereby limiting the rate of rewinding of said strip to a constant rate.
Claim 3
Dependent Claim
148 words
A card reader transport mechanism, comprising: a base, a displaceable element mounted on said base and adapted for manual displacement from a first position to a second position along said base, a retraction mechanism responsive to displacement of said element to said second position to cause return displacement of said element to said first position, said displaceable element adapted to be engageable on an encoded card to transport said card upon displacement of said element from said second position to said first position, means on said base for mounting a read head in fixed position on said base whereby said read head is adapted to serially scan across the encoded card upon transport thereof from said second position to said first position, and a dash-pot mounted on said base and opposing said retraction mechanism for controlling the velocity of said displacement of said card past said read head.
Claim 4
Dependent Claim
148 words
A card reader transport mechanism, comprising: a base, a displaceable element mounted on said base and adapted for manual displacement from a first position to a second position along said base, a retraction mechanism responsive to displacement of said element to said second position to cause return displacement of said element to said first position, said displaceable element adapted to be engageable on an encoded card to transport said card upon displacement of said element from said second position to said first position, means on said base for mounting a read head in fixed position on said base whereby said read head is adapted to serially scan across the encoded card upon transport thereof from said second position to said first position, and a dash-pot mounted on said base and opposing said retraction mechanism for controlling the velocity of said displacement of said card past said read head.
Claim 5
Dependent Claim
67 words
The structure as recited in claim 2, wherein, said dash-pot includes a piston slidably traversable within an outer casing, said piston having a rod coupled to said retraction mechanism, and said casing having a selectively variable orifice which may be adjusted to throttle the rate at which ambient air enters said casing to thereby throttle the rate at which said piston is traversed within said casing .
Claim 6
Dependent Claim
49 words
The structure as recited in claim 2, and further including: a roller, and means for resiliently biasing said roller toward said read head, whereby said encoded card is receivable between said read head and said roller upon transport of said card from said second position to said firSt position.
