Claim 1
Independent Claim
126 words
A pickup actuator comprising: a pickup holder for supporting pickup means; means for generating at least a line of magnetic force of one direction of lines of magnetic forces of two directions perpendicular to each other; a first coil and a second coil having a first path of current and a second path of current respectively perpendicular to each other in a plane perpendicular to said line of magnetic force, said first coil and said second coil being secured to said pickup holder; and control means for effecting selective control of a current passed to said first coil and said second coil; whereby said pickup holder can be independently driven to move at least in two axis directions of three axis directions perpendicular to one another.
Claim 2
Dependent Claim
126 words
A pickup actuator comprising: a pickup holder for supporting pickup means; means for generating at least a line of magnetic force of one direction of lines of magnetic forces of two directions perpendicular to each other; a first coil and a second coil having a first path of current and a second path of current respectively perpendicular to each other in a plane perpendicular to said line of magnetic force, said first coil and said second coil being secured to said pickup holder; and control means for effecting selective control of a current passed to said first coil and said second coil; whereby said pickup holder can be independently driven to move at least in two axis directions of three axis directions perpendicular to one another.
Claim 3
Dependent Claim
176 words
A pickup actuator comprising: a pickup holder for supporting pickup means; means for generating lines of magnetic forces of two directions perpendicular to each other; a first coil and a second coil having a first path of current and a second path of current respectively disposed in one of said lines of magnetic force perpendicular to each other and perpendicular to each other in a plane perpendicular to said line of magnetic force, said first coil and said second coil being secured to said pickup holder; a third coil having a third path of current disposed in the other line of magnetic force and parallel to one of said first path of current and said second path of current in a plane perpendicular to said the other line of magnetic force, said third coil being secured to said pickup holder; and control means for effecting selective control of a current passed to said first to the third coils whereby said pickup holder can be independently driven to move in three axis directions perpendicular to one another.
Claim 4
Dependent Claim
176 words
A pickup actuator comprising: a pickup holder for supporting pickup means; means for generating lines of magnetic forces of two directions perpendicular to each other; a first coil and a second coil having a first path of current and a second path of current respectively disposed in one of said lines of magnetic force perpendicular to each other and perpendicular to each other in a plane perpendicular to said line of magnetic force, said first coil and said second coil being secured to said pickup holder; a third coil having a third path of current disposed in the other line of magnetic force and parallel to one of said first path of current and said second path of current in a plane perpendicular to said the other line of magnetic force, said third coil being secured to said pickup holder; and control means for effecting selective control of a current passed to said first to the third coils whereby said pickup holder can be independently driven to move in three axis directions perpendicular to one another.
Claim 5
Dependent Claim
123 words
A pickup actuator comprising: a pickup holder (1) for supporting pickup means; and support means for supporting said pickup holder for movement in all the coordinate axis directions of the three coordinate axes perpendicular to one another, said support means comprising: a support member (2) for supporting said pickup holder (1) on a frame (3) formed of viscoelastic material and connected between said pickup holder (1) and said frame (3) while being tensioned, said support member (2) having one end (33, 34) affixed to said pickup holder (1) disposed in a plane perpendicular to an arbitrarily selected one coordinate axis (z-axis) and the other end (31, 32) affixed to said frame (3) disposed in a plane perpendicular to said one coordinate axis direction.
Claim 6
Dependent Claim
123 words
A pickup actuator comprising: a pickup holder (1) for supporting pickup means; and support means for supporting said pickup holder for movement in all the coordinate axis directions of the three coordinate axes perpendicular to one another, said support means comprising: a support member (2) for supporting said pickup holder (1) on a frame (3) formed of viscoelastic material and connected between said pickup holder (1) and said frame (3) while being tensioned, said support member (2) having one end (33, 34) affixed to said pickup holder (1) disposed in a plane perpendicular to an arbitrarily selected one coordinate axis (z-axis) and the other end (31, 32) affixed to said frame (3) disposed in a plane perpendicular to said one coordinate axis direction.
