Abstract
Abstract A data card transporting apparatus for scanning a data card is provided which includes a head adapted for selectively scanning one of a plurality of data channels on the card, said head being driven by a lead screw which in turn is driven incrementally by a solenoid actuated device, which includes pins mounted on a disc and driven by pawls in either of two rotary directions to drive the lead screw. A drive is provided for the data card which consists of a capstan on each side of the card with which there is provided a cooperating pinch roller which is actuated by the use of a corresponding solenoid. An ejection mechanism is also provided which consists of a lever which engages an end of the card when the latter is in fully inserted position, the lever being solenoid actuated to impel the card to a position whereat it may be engaged by one of the aforesaid capstan and pinch roller arrangements. Additionally, the head is especially arranged to be accommodated in a trough provided in the bed of the device so that the card, in effect, is pressed into the trough by the head to provide for optimum contact conditions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
Data card transport and read/write apparatus comprising first means to receive a card having multiple parallel data tracks thereon, second means to displace the thusly received card in opposite directions, third means to scan a track on the thusly displaced card for purposes of reading and/or writing data thereon, and fourth means for incrementally stepping said third means from track to track, said third means including a lead screw, and a track scanning head coupled to said screw and responsive to rotation of the latter for being displaced from track to track, said fourth means incrementally rotating said screw, said fourth means including a disc mounted on said screw, pins on said disc and parallel with said screw, members selectively operable to engage and displace said pins to rotate the screw in one of two opposite rotary directions, and solenoids to actuate said members.
Claim 2
Dependent Claim
144 words
Data card transport and read/write apparatus comprising first means to receive a card having multiple parallel data tracks thereon, second means to displace the thusly received card in opposite directions, third means to scan a track on the thusly displaced card for purposes of reading and/or writing data thereon, and fourth means for incrementally stepping said third means from track to track, said third means including a lead screw, and a track scanning head coupled to said screw and responsive to rotation of the latter for being displaced from track to track, said fourth means incrementally rotating said screw, said fourth means including a disc mounted on said screw, pins on said disc and parallel with said screw, members selectively operable to engage and displace said pins to rotate the screw in one of two opposite rotary directions, and solenoids to actuate said members.
Claim 3
Dependent Claim
93 words
Apparatus as claimed in claim 1 wherein said disc is provided with peripheral notches corresponding in number to said pins, said fourth means including a rider adapted to engage sequentially in said notches to hold said disc and thus said screw in positions whereat said head is aligned selectively with respective of said tracks, means resiliently bearing against said rider to maintain the same in said notches, and arms on said members to act against the latter said means to release said rider concomitantly with the displacement of the pins by said members.
Claim 4
Dependent Claim
31 words
Apparatus as claimed in claim 2 comprising a magnet on said rider and a reed switch adjacent the magnet to determine when the rider is in and out of the notches.
Claim 5
Dependent Claim
98 words
Apparatus as claimed in claim 3 wherein said members are hook shaped members pivotally arranged on opposite sides of said disc and adapted for displacement from a rest position to sweep said pins through a limited displacement until said rider engages in a notch and then to return to said rest position, said fourth means including springs allowing said hook shaped members to brush past said pins on returning to said position of rest, said pins being maintained in stationary attitude by engagement of the rider in one of said notches while the members brush past the pins.
Claim 6
Dependent Claim
139 words
Data card transport and read/write apparatus comprising first means to receive a card having multiple parallel data tracks thereon, second means to displace the thusly received card in opposite directions, third means to scan a track on the thusly displaced card for purposes of reading and/or writing data thereon, and fourth means for incrementally stepping said third means from track to track, said third means including a lead screw, and a track scanning head coupled to said screw and responsive to rotation of the latter for being displaced from track to track, said fourth means incrementally rotating said screw, said apparatus further comprising a pivoted arm including one end engaged by and displaced by said head and a second end, an indicator on said second end, and an index cooperating with said indicator to indicate the track being scanned.
Claim 7
Dependent Claim
139 words
Data card transport and read/write apparatus comprising first means to receive a card having multiple parallel data tracks thereon, second means to displace the thusly received card in opposite directions, third means to scan a track on the thusly displaced card for purposes of reading and/or writing data thereon, and fourth means for incrementally stepping said third means from track to track, said third means including a lead screw, and a track scanning head coupled to said screw and responsive to rotation of the latter for being displaced from track to track, said fourth means incrementally rotating said screw, said apparatus further comprising a pivoted arm including one end engaged by and displaced by said head and a second end, an indicator on said second end, and an index cooperating with said indicator to indicate the track being scanned.
Claim 8
Dependent Claim
128 words
Data card transport and read/write apparatus comprising first means to receive a card having multiple parallel data tracks thereon, second means to displace the thusly received card in opposite directions, third means to scan a track on the thusly displaced card for purposes of reading and/or writing data thereon, and fourth means for inCrementally stepping said third means from track to track, said third means including a lead screw, and a track scanning head coupled to said screw and responsive to rotation of the latter for being displaced from track to track, said fourth means incrementally rotating said screw, the card having a position of rest, said apparatus further comprising a lever for ejecting the card from said position of rest and a solenoid to actuate said lever.
Claim 9
Dependent Claim
128 words
Data card transport and read/write apparatus comprising first means to receive a card having multiple parallel data tracks thereon, second means to displace the thusly received card in opposite directions, third means to scan a track on the thusly displaced card for purposes of reading and/or writing data thereon, and fourth means for inCrementally stepping said third means from track to track, said third means including a lead screw, and a track scanning head coupled to said screw and responsive to rotation of the latter for being displaced from track to track, said fourth means incrementally rotating said screw, the card having a position of rest, said apparatus further comprising a lever for ejecting the card from said position of rest and a solenoid to actuate said lever.
