Abstract

A deck of cards is coded by marking each card on its face with a bar code which is essentially invisible to the human eye, but can be read by a detector matched to the source of wavelength of the light used to irradiate each card as it is passed over the surface of a portable housing which houses the detector and the associated reading means. Appropriate hardware is also housed in the housing to process the coded information read. The software provided stores a number of predetermined "hands" which are to be dealt. It can also deal a random deal, more random than can be dealt by human shuffling of the deck. A method is provided to deal a preselected "deal" to a chosen number of players, typically four, the apparatus indicating to the human dealer to which location each card is to be dealt.

Claims

1. An apparatus for manually dealing coded playing cards to each of plural locations so that a preselected set of cards will be dealt to each specific location, without contacting the sides of the cards, the apparatus comprising, a housing having a platform with a surface over which a plurality of coded cards are passed face down and read, one card at a time;

reading means for electro-optically reading each said one card as it is moved past the reading means without using a guide means to orient the card;

means for storing the number of predetermined "hands" or sets which are to be dealt as chosen;

code-processing means for processing the code read from each card in a predetermined manner to execute a program which identifies each location to which each card is to be dealt; and

,

indicating means to indicate the location to which said each card read, is to be dealt.

2. The apparatus of claim 1 wherein said electro-optical reading means is sensitive to actinic radiation in the wavelength range above about 7000 Angstroms (700 nm) but below about 2.2×

10⁵ Angstroms.

3. The apparatus of claim 2 wherein said area of said deck is comparably similar in area to that of said playing card, said reading means is a light source and matching detector mounted within said housing and directed upwardly through a portion of said surface, said portion being permeable to the wavelength to which said detector and source are sensitive;

and said apparatus is portable.

4. The apparatus of claim 3 wherein said code-processing means permits a dealer to verify the location to which a card is designated, at any time during or after the deal.

5. The apparatus of claim 4 wherein said code-processing means is a solid-state device with no moving parts, hence essentially free of risk of failure due to mechanical malfunctions.

6. The apparatus of claim 5 wherein said actinic radiation is in the infrared wavelength, said reading means comprises an infrared light source and matching detector.

7. The apparatus of claim 5 wherein said actinic radiation is in the ultraviolet wavelength, said reading means comprises an ultraviolet light source and matching detector selected from a visible light detector and an ultraviolet light detector.

8. The apparatus of claim 5 wherein said actinic radiation is in the visible wavelength, said reading means comprises a visible light source and matching infrared detector.

9. A method for manually sorting while dealing a set of coded cards having an essentially invisible bar code printed on the face of each card without contacting the sides of the cards, comprising,

manually sliding said cards, one at a time, face downwards, over the upper surface of a card reading means;

reading each card electro-optically as it is moved past the reading means without using a guide means to orient the card;

storing a number of predetermined "hands" or sets which are to be dealt as chosen;

processing the code read from each card in a predetermined manner to execute a program which identifies each location to which each card is to be dealt;

electronically indicating the location to which said each card read, is to be dealt; and

,

manually dealing each of the coded playing cards to each of plural locations indicated, so that a preselected set of cards will be dealt to each specific location.
