First Claim
Patent Images
1. A card inspection device comprising:
- a first loading area adapted to receive one or more decks of playing cards;
a drive roller located adjacent the loading area and positioned to impinge on a card if a card were present in the loading area;
the loading area having an exit through which cards are urged, one at a time, by a feed roller;
a transport path extending from the loading area exit to a card accumulation area;
the transport path further defined by two pairs of transport rollers, one roller of each pair above the transport path and one roller of each pair below the transport path;
a camera located between the two pairs of transport rollers;
a processor for governing the operation of a digital camera and rollers;
a printer for producing a record of the device'"'"'s operation based on an output of the processor;
an accumulation area that also serves as a second loading area;
the second loading area having a second feed roller;
the second feed roller adapted to impinge on a card and insert it into the transport path; and
the transport rollers being bidirectional so that a card may be loaded into either the first loading area or the second loading area.

Abstract
A card inspection device includes a first loading area adapted to receive one or more decks of playing cards. A drive roller is located adjacent the loading area and positioned to impinge on a card if a card were present in the loading area. The loading area has an exit through which cards are urged, one at a time, by a feed roller. A transport path extends from the loading area exit to a card accumulation area. The transport path is further defined by two pairs of transport rollers, one roller of each pair above the transport path and one roller of each pair below the transport path. A camera is located between the two pairs of transport rollers, and a processor governs the operation of a digital camera and the rollers. A printer produces a record of the device'"'"'s operation based on an output of the processor, and a portion of the transport path is illuminated by one or more blue LEDs.
