Abstract:
To provide a linear motion and rotation detector in which a size thereof in a linear motion direction is able to be minimized. A linear motion and rotation detector ( 7 ) includes a cylindrical magnetic scale ( 8 ) that moves linearly in an axial direction (X) and rotates in a direction around an axis, a first magnetic detection element ( 41 ) configured to detect a linear motion position, and a second magnetic detection element ( 42 ) configured to detect a rotational position. The magnetic scale ( 8 ) includes a lattice-shaped magnetized pattern ( 37 ) in which S poles and N poles are alternately arranged in the axial direction (X) and S poles and N poles are alternately magnetized in the direction around the axis on a circumferential surface thereof. 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 rotational position are able to be detected using the first magnetic detection element ( 41 ) and the second magnetic detection element ( 42 ) which face the same magnetized pattern, it is unnecessary to arrange the linear motion scale and the rotational scale at different positions in the axial direction (X). Thus, an increase in size of the linear motion and rotation detector ( 7 ) in the axial direction (X) can be minimized.
