Card dispensing apparatus for card vending machine
First Claim
1. A card dispensing apparatus for card vending machines comprising a vertical store room defined between two parallelly spaced side plates for holding a stack of cars, a draw roller positioned under the stack for drawing out a card from the bottom of the stack, a delivery roller for delivering the drawn card towards an outlet, a card antidoubling roller positioned just above the delivery roller, and a reversible motor for reversibly rotating the rollers, the antidoubling roller being rotatably mounted on a reversible roller shaft rotated in the opposite direction relative to the rotational direction of the delivery roller and including an end and an engaging arm extending in the axial direction from the end of the antidoubling roller, the reversible roller shaft having a driving pin extended in a radial direction such as to engage the engaging arm to drive the antidoubling roller.

Abstract
A card dispensing apparatus is disclosed of a type comprising a draw roller for drawing a card to be dispensed from a bottom of a stack of cards and a delivery roller for delivering the drawn card toward an outlet of the apparatus. The card dispensing apparatus further comprises an antidoubling roller positioned above the delivery roller and reversely rotated relative to the delivery roller to preventing an upper card of two overlapped cards from delivering to the outlet.

3. A card dispensing apparatus for card vending machines comprising a vertical store room defined between two parallelly spaced side plates for holding a stock of cards, a reversible draw roller positioned under the stack for drawing out a card from the bottom of the stack, a reversible delivery roller for delivering the drawn card towards an outlet, a card antidoubling roller positioned above the delivery roller, and a reversible motor for reversibly rotating the rollers, the card antidoubling roller being rotatbly mounted on a reversible roller shaft rotated in the opposite direction relative to the rotational direction of the delivery roller and having an engaging arm extended in the axial direction from an end of the antidoubling roller, the reversible roller shaft having a driving pin extended in a radial direction such as to engage the engaging arm to drive the antidoubling roller to cause two overlapped cards inserted between said delivery and antidoubling rollers to be returned to an aligned position at the bottom of the stack of cards upon the reverse rotation of the reversible motor.

4. A card dispensing apparatus for card vending machines comprising a vertical store room defined between two parallelly spaced side plates for holding a stack of cards;
- a draw roller means including a draw roller mounted under said stack for drawing out a card from the bottom of the stack;
a delivery roller means including a delivery roller mounted for rotation either in one direction for delivering said drawn card towards an outlet or in a reverse direction for delivering a card back to said stack;
a card antidoubling roller means including an antidoubling roller mounted above said delivery roller on a reversible roller shaft rotatable in an opposite direction relative to the rotational direction of said delivery roller;
a reversible motor means mounted for selectably rotating said delivery and antidoubling rollers in reverse directions;
an overload signal sensing means operative to generate an overload signal to reverse said motor means when a plurality of cards are inserted between said delivery and antidoubling rollers; and
free rotation means operatively interconnected between said reversible roller shaft and said antidoubling roller to permit continued limited rotation in said opposite direction upon reverse rotation of said motor means in response to said overload signal so that said plurality of cards are returning to an aligned position at the bottom of said stack of cards.
- a draw roller means including a draw roller mounted under said stack for drawing out a card from the bottom of the stack;
