Apparatus according to claim 1, wherein said disc is provided with a plurality of projecting formations spaced circumferentially around and proximate the periphery of said disc, said formations being arranged to carry respective chips from said store to said conveyor means as said disc rotates about said axis.

Claim 4

Apparatus according to claim 2 wherein the projecting formations comprise pins arranged in pairs, each pair of pins being arranged to carry a respective individual chip.

Claim 5

Apparatus according to claim 1, wherein the disc is rotatably driven.

Claim 6

Apparatus according to claim 4 wherein the speed of rotation of the disc is adjustable.

Claim 7

Apparatus according to claim 1, further provided with deflector means arranged to lift individual ones of said chips from said first transfer means and position said chips in/on said conveyor means.

Claim 8

Apparatus according to claim 6, wherein said deflector means comprises an elongate finger arranged to lift and deflect said chips from the surface of said rotating disc.

Claim 9

Apparatus according to claim 7, wherein a circular groove or slot is provided proximate said periphery of said disc within which the distal end of said finger member is received.

Claim 10

Apparatus according preceding claim 1, wherein said conveyor means comprises a plurality of chip collector apertures adapted to collect and retain respective individual ones of said chips.

Claim 11

Apparatus according to claim 9, wherein one or more resiliently deformable elements are provided around respective collector apertures such that respective chips are securely retained therein.

Claim 12

Apparatus according to claim 9, wherein said collector apertures are shaped and dimensioned such that the respective chips enter and are located in said aperture from one side of the aperture and the ejected through the opposed side of the respective aperture.

Claim 13

Apparatus according to claim 9, wherein said conveyor comprises a plurality of linked elements, each element being provided with an individual chip retaining aperture.

Claim 14

Apparatus according to claim 12, wherein said conveyor elements are pivotally linked such that adjacent elements may pivot relative to one another.

Claim 15

Apparatus according to claim 1, wherein the speed of the conveyor means and transfer means is monitored and controlled such that the speed of the conveyor means and the speed of the transfer means is maintained substantially identical.

Claim 16

Apparatus according to claim 1, wherein said chip ejector means comprises an array of chip ejectors arranged in side by side relationship.

Claim 17

Apparatus according to claim 15, wherein the chip ejectors are solenoid actuated.

Claim 18

Apparatus according to claim 15, wherein a corresponding receptacle is provided adjacent each chip ejector with the path of the conveyor means lying intermediate the chip ejector and respective receptacle.

Claim 19

Apparatus according to claim 1, wherein said chip ejector means is actuable in response to an actuation signal provided by signal processing means acting on an output signal from said sensing means.

Claim 20

Apparatus according to claim 1, wherein the sensing means comprises a charge coupled device arranged to produce a digital output dependent on the color of the chip being sensed.

Claim 21

An apparatus according to claim 1, wherein: said transfer of said chips from said transfer means to said conveyor occurs at substantially the highest point on said transfer means.

Claim 22

Apparatus for sorting a plurality of differently identified gaming chips, said apparatus comprising transfer means arranged to remove individual ones of said chips from a store of randomly arranged chips and transfer said chips in sequence to conveyor means, said conveyor means being arranged to carry said chips in sequence first to sensing means arranged to sense an identifiable characteristic of said individual chips, and subsequently to chip ejector means arranged to remove individual ones of said chips from said conveyor means and deposit individual said chips in a respective selected one of a plurality of receptacles depending on the characteristic of said individual chip identified by said sensing means, said transfer means comprising a substantially planar disc having a central axis and being rotatable about said central axis, the plane of the disc being inclined at an acute angle to the horizontal, said disc being provided with a plurality of projecting pins arranged in respective pairs around the periphery of the disc each pair arranged to carry a respective individual chip from said store to said conveyor means as said disc rotates about said axis.

Claim 23

Apparatus for sorting a plurality of differently identified gaming chips, said apparatus comprising transfer means arranged to remove individual ones of said chips from a store of randomly arranged chips and transfer said chips in sequence to conveyor means, said conveyor means being arranged to carry said chips in sequence first to sensing means arranged to sense an identifiable characteristic of said individual chips, and subsequently to chip ejector means arranged to remove individual ones of said chips from said conveyor means and deposit individual said chips in a respective selected one of a plurality of receptacles depending on the characteristic of said individual chip identified by said sensing means, said transfer means comprising a substantially planar disc having a central axis and being rotatable about said central axis, the plane of the disc being inclined at an acute angle to the horizontal, said disc being provided with a plurality of projecting pins arranged in respective pairs around the periphery of the disc each pair arranged to carry a respective individual chip from said store to said conveyor means as said disc rotates about said axis.
