Abstract:
Provided is a linear motion and rotation drive apparatus capable of minimizing inertia due to a magnetic scale attached to an output shaft when the output shaft is linearly moved or rotate. A linear motion and rotation drive apparatus ( 1 ) includes an output shaft ( 2 ), a linear motor ( 3 ), a rotational motor ( 4 ), a ball spline bearing ( 5 ), a magnetic scale ( 8 ), a first magnetic detection element ( 41 ) configured to detect a linear motion, and a second magnetic detection element ( 42 ) configured to detect a rotational motion. The magnetic scale ( 8 ) includes a lattice-shaped magnetized pattern ( 37 ) in which S poles and N poles are alternately arranged in an axis L direction and S poles and N poles are alternately magnetized in a direction around the axis (L) on a circumferential surface thereof in the direction around an axis (L). The first magnetic detection element ( 41 ) and the second magnetic detection element ( 42 ) are disposed to face the magnetized pattern ( 37 ). Since a linear motion position and a rotating position can be detected using the first magnetic detection element ( 41 ) and the second magnetic detection element ( 42 ) that face the same magnetized pattern ( 37 ), a size of a linear motion and rotation detector ( 7 ) in the axis L direction is not increased and a weight thereof is not increased.

Claim (Index 7):
The linear motion and rotation drive apparatus according according to  claim 3 , wherein the first magnetic detection element and the second magnetic detection element are stacked above the sensor substrate.
