Abstract An apparatus to be incorporated in a automatic vending machine or the like for mechanically selecting coins particularly by detecting whether coins have a milled peripheral edge. A coin selecting annular member formed on its periphery with indentations and projections engageable with those of a genuine coin projects into a passage along which coins roll down in upright position. The selecting member is loosely and eccentrically supported on a pin fixedly disposed above the passage such that the projections substantially block part of upper portion of the passage. When a coin strikes against the selecting member, the selecting member rocks on the support pin to permit the milled edge of the coin to mesh with that of the selecting member, whereby the selecting member is substantially rotated and raised. Thus only genuine coins are allowed to pass by the selecting member. Other coins or the like are stopped in the passage by the projections of the selecting member or caused to drop thereafter. A second selecting member rotatably disposed in the rear of the selecting member has a projecting piece which projects to a greater extent than the projections on the first-mentioned selecting member and blocks part of upper portion of the passage. In this construction, the first selecting member has a lever portion which rests on the second selecting member to load the same with its weight. The first selecting member, when rotationally raised as above, frees the second selecting member from its weight, permitting the second selecting member to be rotated by striking force of a rolling coin. Accordingly, genuine coins pass by the first and second selecting members. The apparatus comprising the first and second selecting members thus assures secondary selection.

Claim 1
Independent Claim
156 words
In an apparatus for selecting coins by detecting the peripheral milled edge of the coin and the diameter of the coin wherein a passage adapted for the rolling passage of coins in an upright position is provided at its one side with a tumbling window narrower than the outer diameter of a genuine coin including the projections of the milled edge thereof characterized by a support pin disposed at one side of said passage above said window and having a circular section and an annular selecting member having a precisely circular pin bore and a mIlled periphery complementary to and in conformity with the milled edge of the coin and eccentrically loosely supported on said pin to permit part of the milled periphery to project from said window continuously, the milled periphery of said selecting member being meshable with the milled edge of the genuine coin when said selecting member is in its uppermost elevated position.
Claim 2
Dependent Claim

In an apparatus for selecting coins by detecting the peripheral milled edge of the coin and the diameter of the coin wherein a passage adapted for the rolling passage of coins in an upright position is provided at its one side with a tumbling window narrower than the outer diameter of a genuine coin including the projections of the milled edge thereof characterized by a support pin disposed at one side of said passage above said window and having a circular section and an annular selecting member having a precisely circular pin bore and a mIlled periphery complementary to and in conformity with the milled edge of the coin and eccentrically loosely supported on said pin to permit part of the milled periphery to project from said window continuously, the milled periphery of said selecting member being meshable with the milled edge of the genuine coin when said selecting member is in its uppermost elevated position.
Claim 3
Dependent Claim
241 words
In an apparatus for selecting coins by detecting the peripheral milled edge of the coin characterized by a support pin disposed above and at one side of a passage adapted for the rolling passage of coins in an upright position, a first selecting member having an annular base portion and a precisely circular bore loosely supported at its circular bore on said support pin, the annular base portion of said selecting member having a milled periphery including at least one projection meshable with the milled edge of a genuine coin, said selecting member being so positioned as to cause the milled periphery thereof to block part of the upper portion of said passage, the milled periphery being meshable with the milled edge of the genuine coin when the base portion is in its uppermost elevated position, and a second selecting member disposed close to said first selecting member and having a stopper piece projectable into said passage to a greater extent than the milled base portion of said first selecting member, said first and second selecting members being retainable in balance with each other before coin selection with the milled portion and stopper piece thereof partially blocking said passage respectively, said first selecting member being movable out of said passage for coin selection to thereby move said second selecting member and disturb the balance between said members, said first and second selecting members being returnable to balance again after coin selection.
Claim 4
