Table system with angular position controls

A table system with angular position control means, comprising a flat bed, a table supported on the bed for rotation through a first bearing means, an arm plate extending radially out of an outside periphery of the table, and

• a position control means arranged in a position flanking a side of the bed to move the table over a tiny angle with respect to the bed in a circular direction through the arm plate,
• wherein the position control means is comprised of a motor mounted to a motor bracket that is secured to the side of the bed, a screw shaft lying lengthwise along the side of the bed and connected with a rotary shaft of the motor, a nut mating with the screw shaft to move along the screw shaft as the screw shaft rotates on its own axis, a first liner motion guide unit composed of a first track rail arranged in a way extending lengthwise of the side of the bed and a first slider moveable along the track rail, a carriage fastened to both the first slider and the nut, and
• a joining means for joining the carriage with the arm plate to translate a linear movement of the carriage caused by the motor into a circular movement over the tiny angle of the arm plate, and
• wherein the joining means is composed of a second bearing means on the carriage, a turret means that is supported on the carriage, a turret means that is supported on the carriage for rotation through the second bearing means, and a second linear motion guide unit connecting the turret means to the arm plate whereby the linear movement of the carriage caused by the motor is translated into the circular movement of the arm plate.
