Card reading system

Details

Inventors: Stiller, Bruno V.;

A system for generating a unique signal indicative of a particular identity carried by a card. The card has a series of zones along the sides thereof with holes extending through one or more of the zones. A receptacle is provided for the card, the receptacle including a longitudinal internal slot and a series of opto-electronic sensors which are spaced along the slot such that when the card is inserted within the slot, one of the sensors is positioned in registration with each of these zones. The card and the receptacle are formed such that the card can be inserted in the slot in only one proper orientation. One or more of the sensors is employed solely for determining proper insertion of the card.

DETAILED DESCRIPTION The invention comprises a system for generating a unique indication of an identity carried by a card.
Primary components of the invention comprise a card which has a plurality of defined zones thereon, each zone having means to create an indication representative of a particular binary condition of the zone, and a receptacle for the card.
The receptacle includes a plurality of card-reading elements spaced such that when the card is inserted within the receptacle, one card-reading element is positioned in registration with each zone on the card.
The system is configured such that there is only one proper means of insertion of the card within the receptacle.
The receptacle has a longitudinal internal slot to accommodate insertion of the card.
To assure proper orientation of the card within the receptacle, the receptacle has an indented guide adjacent the slot and the card has a corresponding protrusion extending outwardly therefrom which engages the guide when the card is inserted within the slot.
The guide has a stop against which the protrusion seats to locate the card when inserted within the slot.
In accordance with the preferred embodiment of the invention, the protrusion includes a depression to aid the user when grasping the card.
Furthermore, the slot in the receptacle extends the length of the receptacle in order to permit flat foreign objects, such as coins and the like, which are inadvertently or maliciously inserted therein, to pass through the receptacle without activating the reading elements therein.
In order to create the indication of a particular binary condition of a zone, each zone has either a hole therein or the absence of a hole which are equivalent to a binary zero or a binary one.
The zones are preferrably located along the side edges of the card and at least one of the zones is positioned to indicate the proper insertion of the card within the receptacle.
A plurality of opto-electronic sensors are installed within the receptacle such that when the card is properly and fully inserted within the receptacle, one such sensor aligns with each zone in order to detect the presence or absence of a hole through that zone
