Abstract
Abstract The stacker for a paper sheet counting apparatus of the present invention has a rotatable drum and a plurality of rigid, substantially L-shaped blade members mounted on and around the drum periphery in equally spaced apart relation to one another. Each blade member has one end mounted for limited, free pivotal movement on the drum and its other and extending in a direction opposite to the intended rotational direction of the drum, the pivotal movement of each blade being responsive to rotation of the drum in such manner that the radius of rotation of said radial distance of projection of its other end away from the drum periphery is increased and decreased during rotation of the drum.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
156 words
A stacker for a paper sheet counting apparatus comprising a rotatable drum, and a plurality of radially projecting blade members mounted substantially on and around the periphery of the drum in equally spaced apart relation from each other, each of said blade members being rigid and having substantially L-shaped configuration to provide first and second length portions of the blade member disposed in angular relation to each other, said first length portion having a free end mounted for freely pivotal movement on said drum for limited arcuate movement of said first length portion along said drum periphery and said second length portion extending from the opposite end of said first length portion in a direction opposite to the intended rotational direction of the drum, whereby the free end of said second length portion moves towards and away from said drum periphery responsive to said limited arcuate movement of said first length portion in respectively opposite directions.
Claim 2
Dependent Claim
156 words
A stacker for a paper sheet counting apparatus comprising a rotatable drum, and a plurality of radially projecting blade members mounted substantially on and around the periphery of the drum in equally spaced apart relation from each other, each of said blade members being rigid and having substantially L-shaped configuration to provide first and second length portions of the blade member disposed in angular relation to each other, said first length portion having a free end mounted for freely pivotal movement on said drum for limited arcuate movement of said first length portion along said drum periphery and said second length portion extending from the opposite end of said first length portion in a direction opposite to the intended rotational direction of the drum, whereby the free end of said second length portion moves towards and away from said drum periphery responsive to said limited arcuate movement of said first length portion in respectively opposite directions.
Claim 3
Dependent Claim
55 words
The stacker as claimed in claim 1, wherein the peripheral surface of the drum is formed with a plurality of substantially V-shaped grooves corresponding to the respective of said blade members, said free end of each of said blade member first length portions being pivotally mounted at the bottom of its said associated V-shaped groove.
Claim 4
Dependent Claim
44 words
The stacker as claimed in claim 2, wherein each said blade member is restrained from rotation during rotation of the drum by said first length portion thereof abutting on the upstream side wall of said recess relative to the rotational direction of the drum.
Claim 5
Dependent Claim
60 words
The stacker as claimed in claim 3, wherein said free end of each said blade member first length portion is formed as a shaft extending in the direction of the drum axis, and wherein a cylindrical recess is formed at the bottom of said substantially V-shaped groove to which said free end is pivotally mounted, said recess accommodating said shaft.
