Abstract
Abstract A magnetically selective token system comprises valid tokens which are nonmagnetically responsive in the peripheral portions thereof and responsive in the central portions thereof and a token acceptor which is operative for segregating valid tokens from various types of counterfeit tokens. Unspecified tokens inserted into the acceptor are individually passed to an upper token station where first magnetic elements are operative for magnetically communicating with only the peripheral portions of the tokens so that counterfeit tokens having magnetically responsive peripheral portions are retained at the upper station, whereas other types of unspecified tokens are individually passed to a lower station. Second magnetic elements are operative for magnetically communicating with the central portions of tokens at the lower station so that valid tokens are retained at the lower station, whereas nonmagnetically responsive counterfeit tokens pass to a first outlet slot. The acceptor is operative for removing counterfeit tokens from the upper station and guiding them to the first outlet slot and for removing valid tokens from the lower station and guiding them to a second outlet slot so that they are segregated from the counterfeit tokens. The method of segregating valid tokens from counterfeit tokens includes the steps of exposing only the peripheral portions of unspecified tokens to first magnetic elements to separate out magnetically responsive counterfeit tokens and then exposing the central portions of the remaining token to second magnetic elements to separate out valid tokens.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
256 words
A magnetically selective token system comprising: (a) a magnetically responsive valid token having a nonmagnetically responsive peripheral portion; and (b) a token acceptor comprising: (i) an acceptor body made of nonmagnetically responsive material having a token inlet slot and first and second token outlet slots therein, said body also having an upper token station therein for receiving tokens from said inlet slot and a lower token station therein for receiving tokens from said upper station; (ii) first magnetic means operative at said upper token station for magnetically communicating with the peripheral edge portions of a valid token positioned at said upper station but not with other portions of said valid token so that when said valid token is positioned at said upper station it is substantially unaffected by said first magnetic means but so that when a magnetically responsive counterfeit token having a similar dimension and configuration to said valid token and having a magnetically responsive peripheral portion is positioned at said upper station it is retained at said upper station by said first magnetic means; (iii) second magnetic means operative at said lower token station for magnetically communicating with the nonperipheral edge portions of said valid token when it is positioned at said lower station to retain it at said lower station; (iv) means operative for removing said counterfeit token from said upper station and for guiding it to said first outlet slot; and (v) means operative for removing said valid token from said lower station and for guiding it to said second outlet slot.
Claim 2
Dependent Claim
256 words
A magnetically selective token system comprising: (a) a magnetically responsive valid token having a nonmagnetically responsive peripheral portion; and (b) a token acceptor comprising: (i) an acceptor body made of nonmagnetically responsive material having a token inlet slot and first and second token outlet slots therein, said body also having an upper token station therein for receiving tokens from said inlet slot and a lower token station therein for receiving tokens from said upper station; (ii) first magnetic means operative at said upper token station for magnetically communicating with the peripheral edge portions of a valid token positioned at said upper station but not with other portions of said valid token so that when said valid token is positioned at said upper station it is substantially unaffected by said first magnetic means but so that when a magnetically responsive counterfeit token having a similar dimension and configuration to said valid token and having a magnetically responsive peripheral portion is positioned at said upper station it is retained at said upper station by said first magnetic means; (iii) second magnetic means operative at said lower token station for magnetically communicating with the nonperipheral edge portions of said valid token when it is positioned at said lower station to retain it at said lower station; (iv) means operative for removing said counterfeit token from said upper station and for guiding it to said first outlet slot; and (v) means operative for removing said valid token from said lower station and for guiding it to said second outlet slot.
Claim 3
Dependent Claim

In the token system of claim 1, said valid token removing means being operative for actuating the operation of a secondary system actuating device in response to the operation of said valid token removing means for removing said valid token.
Claim 4
Dependent Claim
23 words
In the token system of claim 1, said valid token removing means and said counterfeit token removing means being interconnected for simultaneous operation.
Claim 5
Dependent Claim
47 words
In the token system of claim 3, said valid token removing means and said counterfeit token removing means comprising a slide made of a nonmagnetically responsive material, said slide being slidably mounted in said body and communicating along one side thereof with said upper and lower stations.
Claim 6
Dependent Claim
16 words
In the token system of claim 4, said first magnetic means being mounted on said slide.
Claim 7
Dependent Claim
16 words
In the token system of claim 4, said second magnetic means being mounted on said slide.
Claim 8
Dependent Claim
