Abstract
A table system with angular position control in which a table is moved accurately over a tiny angle in circular direction to any desired position. The table is supported on a bed for rotation through a crossed-roller bearing. Position control apparatus turns the table over a tiny angle through an arm plate fastened to the table. A nut and screw set cause a linear motion that is in line with a tangent of the table, and the linear motion is translated into a circular motion to turn the table by a first linear motion guide unit to control the linear motion in the tangential direction, and a second linear motion guide unit to control a linear motion in the direction facing the center of the table.
