Abstract
Abstract A bidirectional stage is disclosed in which the said bidirectional stage may be moved independently in either of two directions while maintaining contact with a stationary reference plane. A guide or motion control member is provided between the reference member and plane and the bidirectional member. The guide member is restricted to a first linear reciprocal motion with respect to the reference member; while the bidirectional stage is restricted to a second linear reciprocal motion with respect to the guide member. The guide member does not support or provide any planar reference for the bidirectional member which refers only to the stationary reference plane.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
In a bidirectional positioning apparatus, the combination comprising: a reference plate having a reference plane; and a bidirectional positioning plate slidably disposed directly and solely on said plane of said reference plate, wherein horizontal spacing of said positioning plate with respect to said reference plate as said positioning of plate slides on said reference plate is determined solely by said plane of said reference plate; and means disposed between said reference plate and said positioning plate for guiding and restricting movement of said positioning plate on said reference plate to reciprocal motion in a first straight line substantially parallel to said reference plane and reciprocal motion in a second straight line substantially parallel to said reference plane, said first straight line and said second straight line being orthogonal to each other.
Claim 2
Dependent Claim
131 words
In a bidirectional positioning apparatus, the combination comprising: a reference plate having a reference plane; and a bidirectional positioning plate slidably disposed directly and solely on said plane of said reference plate, wherein horizontal spacing of said positioning plate with respect to said reference plate as said positioning of plate slides on said reference plate is determined solely by said plane of said reference plate; and means disposed between said reference plate and said positioning plate for guiding and restricting movement of said positioning plate on said reference plate to reciprocal motion in a first straight line substantially parallel to said reference plane and reciprocal motion in a second straight line substantially parallel to said reference plane, said first straight line and said second straight line being orthogonal to each other.
Claim 3
Dependent Claim
88 words
In a bidirectional positioning system, the combination comprising: a reference plate having a planar reference surface; first linear direction guide means provided on said reference plate; a bidirectional plate supported directly and solely on said reference surface of said reference plate; second linear direction guide means provided on said bidirectional plate; and a single guide member in contact with said first guide means and said second guide means for restricting the relative motion between said reference plate and said bidirectional plate to reciprocal motion in two orthogonal directions.
Claim 4
Dependent Claim
88 words
In a bidirectional positioning system, the combination comprising: a reference plate having a planar reference surface; first linear direction guide means provided on said reference plate; a bidirectional plate supported directly and solely on said reference surface of said reference plate; second linear direction guide means provided on said bidirectional plate; and a single guide member in contact with said first guide means and said second guide means for restricting the relative motion between said reference plate and said bidirectional plate to reciprocal motion in two orthogonal directions.
Claim 5
Dependent Claim
156 words
In a bidirectional positioning system according to claim 2 wherein said first linear direction guide means comprises a first longitudinal extending groove having a pair of oppositely facing walls formed in said reference plate; said second linear direction guide means comprises a second longitudinally extending groove having a pair of oppositely facing walls formed in said bidirection plate; and said single guide member includes at least one means extending into said first groove and bearing against said pair of oppositely facing walls of said first groove for restricting horizontal movement of said guide member in a first straight line direction parallel with the longitudinal direction of said first groove, and includes at least one means extending into said second groove and bearing against said pair of oppositely facing walls of said second groove for restricting horizontal movement of said bidirectional plate in a second straight line direction parallel with the longitudinal direction of said second groove.
Claim 6
Dependent Claim
172 words
In a bidirectional positioning system according to claim 2 wherein said first linear direction guide means comprising: a first pair of spaced parallel longitudinally extending elements secured to said reference surface of said reference plate; said second linear direction guide means comprises a second pair of spaced parallel longitudinally extending elements secured to said bidirection plate; and said single guide member includes at least one first pair of oppositely facing elements, respective ones of which bear against respective ones of said first pair of spaced parallel longitudinally extending elements for restricting horizontal movement of said guide member in a first straight line direction parallel with the longitudinal direction of said first pair of spaced parallel longitudinally extending elements, and includes at least one second pair of oppositely facing elements, respective ones of which bear against respective ones of said second pair of spaced longitudinally extending elements for restricting horizontal movement of said bidirectional plate in a second straight line direction parallel with the longitudinal direction of said second pair of longitudinal elements.
