Abstract
Encoded magnetic strip cards are fed into apparatus which reads encoded data on the card. The card is fed into and out of the apparatus through a passageway defined by a guide which also serves as a mount for mechanical and electronic components. The guide is precisely constructed so that the thickness and width of the passageway are slightly greater than the corresponding dimensions of the card and the card does not jam in the passageway. In one form of the invention the guide is formed of two generally T-shaped, overlapping, interfitting members. In a second form of the invention the guide is formed of two opposed T-shaped side members and two plates relieved at their edges to receive the legs of the side members.
Claims4
A guide for a card feed whereby a substanially rectangular card is fed in at least one direction by card feed means for performance of functions on said card, said guide formed with a rectangular passageway to receive said card with slight clearances for the thickness and width of said card, said guide comprising:
- a first member having a first flat surface facing inward of said passageway, a second member having a second flat surface facing inward of said passageway parallel to said first flat surface and spaced therefrom a distance slightly more than the thickness of said card, first side edge guide means having a thin third flat surface facing inward of said passageway and being perpendicular to said first and second surfaces and intersecting said first and second surfaces in sharp corners, and second side edge guide means opposite said first side edge guide means having a thin fourth flat surface facing inward of said passageway and parallel to and of even thickness as said third surface, said third and fourth surfaces being spaced apart a distance slightly more than the width of said card, each of said first and second side edge guide means comprising a member substantially T-shaped in cross-section, said third and fourth surfaces being formed on said first and second side edge guides, respectively.
