Abstract
Abstract A rotating disk (10) is horizontally rotated to feed coins placed thereon toward a rotating body (20). The rotating body (20) is formed with a spiral groove (20a) in which the periphery of each coin is inserted and a guide barrel (21) is disposed in such a manner as to enclose the rotating body. The coins, the periphery of which are engaged in the spiral groove (20a), are received by the guide barrel (21) and lifted in that state according to the rotation of the rotating body and then discharged outside from a discharging port (21b) formed at an upper portion of the guide barrel. A rubber roller (18) is adapted to push the periphery of coins thereby to ensure the insertion of the coins into the spiral groove (20a).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
230 words
A coin lifting device comprising a rotating disk which rotates about an upright axis so as to feed coins placed thereon; a rotating body formed with a spiral groove, in which groove the periphery of the coins fed in a horizontal posture by said rotating disk is inserted, said rotating body being rotatable about an upright axis; guide means disposed at the outer periphery of said rotating body and adapted to receive the coins inserted in said spiral groove and to prevent the coins from being disengaged from said spiral groove and to prevent the coins from revolving about said rotating body; a coin discharge port formed in an upper portion of said guide means and adapted to discharge coins lifted by said spiral groove; a base plate having a circular recess, said rotating disk being rotatably disposed in said circular recess, said base plate having a passageway connected to said recess, said passageway being of a size to pass only a single layer and a single row of coins which have left said rotating disk due to the centrifugal force imparted to the coins by the rotating disk; and a roller which rotates about an upright axis, said roller being so disposed that said passageway is sandwiched between said roller and said rotating body and coins entering said passageway are further pushed toward said rotating body by said roller.
Claim 2
Dependent Claim
230 words
A coin lifting device comprising a rotating disk which rotates about an upright axis so as to feed coins placed thereon; a rotating body formed with a spiral groove, in which groove the periphery of the coins fed in a horizontal posture by said rotating disk is inserted, said rotating body being rotatable about an upright axis; guide means disposed at the outer periphery of said rotating body and adapted to receive the coins inserted in said spiral groove and to prevent the coins from being disengaged from said spiral groove and to prevent the coins from revolving about said rotating body; a coin discharge port formed in an upper portion of said guide means and adapted to discharge coins lifted by said spiral groove; a base plate having a circular recess, said rotating disk being rotatably disposed in said circular recess, said base plate having a passageway connected to said recess, said passageway being of a size to pass only a single layer and a single row of coins which have left said rotating disk due to the centrifugal force imparted to the coins by the rotating disk; and a roller which rotates about an upright axis, said roller being so disposed that said passageway is sandwiched between said roller and said rotating body and coins entering said passageway are further pushed toward said rotating body by said roller.
Claim 3
Dependent Claim
34 words
A coin lifting device as claimed in claim 1, which further includes a spring plate, said spring plate being adapted to press yieldably downwardly on coins located between said roller and said rotating body.
Claim 4
Dependent Claim
24 words
A coin lifting device as claimed in claim 1, wherein said rotating disk, said rotating body and said roller are driven by one motor.
Claim 5
Dependent Claim
22 words
A coin lifting device as claimed in claim 3, wherein said rotating body is connected to said motor through a one-way clutch.
Claim 6
Dependent Claim
154 words
A coin lifting device comprising a rotating disk which rotates about an upright axis so as to feed coins placed thereon; a rotating body formed with a spiral groove, in which groove only the periphery of the coins fed in a horizontal posture by said rotating disk is inserted, said rotating body being rotatable about an upright axis; upright guide means disposed at the outer periphery of said rotating body and adapted to constrain the coins inserted in said spiral groove to remain in said spiral groove and to prevent the coins from revolving about said rotating body; and a laterally-opening coin discharge port formed in an upper portion of said guide means, said guide means terminating upwardly at a lower edge of said discharge port, whereby coins reaching the discharge port lose the constraint of said guide means and are discharged through said discharge port in a direction away from said rotating body.
Claim 7
Dependent Claim
154 words
