A card shuffling device includes a top surface, a card receiving area for receiving an initial set of playing cards, a randomizing system for randomizing the initial set of playing cards, a collection surface in a card collection area for receiving randomized playing cards, the collection surface receiving cards positioned so that all cards collected are below the top surface of the device, and an elevator for raising the collection surface so that at least some randomized cards are elevated above the top surface of the device. An automatic card shuffler includes a microprocessor with memory, an infeed compartment for receiving cards to be randomized, a card moving mechanism for moving cards individually from the infeed compartment into a card mixing compartment, a card mixing compartment comprising a plurality of substantially vertical supports, an opening for the passage of cards from the infeed compartment, a moveable lower support surface, at least one stationary gripping arm, a lower edge proximate the opening, the gripping arm capable of suspending cards above the opening, and an elevator for raising and lowering the moveable support surface. A position of the elevator is randomly selected and the support surface is moved to the selected position, and after the gripping arm grasps at least one side of the cards, the elevator lowers, creating a space beneath the gripping arm, wherein a card is moved from the infeed compartment into the space, thereby randomizing the cards. A method of randomizing a group of cards utilizing the apparatus is disclosed.

A method of randomizing a group of cards utilizing the apparatus is disclosed. k-up roller fixed to and rotatable with said pick-up shaft, said pick-up roller conveying said document to a first position, said pick-up shaft being connected pivotally to said pick-up arm. 3. The document feeding apparatus of claim 2, further comprising a strip roller, and a strip shaft, said strip roller fixed to and rotatable with said strip shaft, said strip roller conveying said document at said first position, said strip shaft being connected to said pick-up arm. 4. The document feeding apparatus of claim 3, further comprising a gear train including a plurality of gears, said gear train transferring a power of said one-way drive gear set to said strip shaft and said pick-up shaft to pick up and stripe said document. 5. The document feeding apparatus of claim 4, wherein said pick-up arm selectively rotates along said strip shaft. 6. The document feeding apparatus of claim 5, wherein, when said cam set rotates in said first direction to operate in said first state, said first cam lowers said paper-stopping arm and said second cam elevates said pick-up arm. 7. The document feeding apparatus of claim 6, wherein, when said cam set rotates in said second direction to operate in said second state, said first cam elevates said paper-stopping arm and said second cam lowers said pick-up arm. 8. The document feeding apparatus of claim 1, wherein said first one-way clutch is a one-way spring clutch. 9. The document feeding apparatus of claim 1, wherein said first one-way clutch is a one-way bearing clutch. 10. The document feeding apparatus of claim 1, wherein said second one-way clutch is a one-way spring clutch. 11. The document feeding apparatus of claim 1, wherein said second one-way clutch is a one-way bearing clutch.
