Abstract
Abstract The disclosure relates to a high speed electronic scanner terminal for scanning information on a column by column basis which is located in switch operated and card operated devices. The system includes a start cycle device which permits an operating cycle to start only if all information containing devices are closed and all card receiving units have data cards inserted in them. The system includes a pair of clocks and converts information readout in one out of ten code one column by column basis into serial code compatible with a remote receiving unit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A data card terminal which comprises a scanner, said scanner including a pair of counting means, first clock means for stepping at least one of said counting means, bistable means responsive to a start signal for placing said bistable means into one of its stable states to activate said first clock means, means responsive to a predetermined count in one of said pair of counting means for controlling said bistable means, means responsive to said pair of counting means for scanning a predetermined column of information and providing a parallel output indication thereof, means for converting said parallel output to a serial output, and second clock means responsive to said bistable means being in the other of its stable states for activating said second clock means.
Claim 2
Dependent Claim
126 words
A data card terminal which comprises a scanner, said scanner including a pair of counting means, first clock means for stepping at least one of said counting means, bistable means responsive to a start signal for placing said bistable means into one of its stable states to activate said first clock means, means responsive to a predetermined count in one of said pair of counting means for controlling said bistable means, means responsive to said pair of counting means for scanning a predetermined column of information and providing a parallel output indication thereof, means for converting said parallel output to a serial output, and second clock means responsive to said bistable means being in the other of its stable states for activating said second clock means.
