A manipulator for moving a workpiece to a given position includes a supporting member, a driving member, a rotary member, a moving member, a speed change mechanism and a chuck member. The supporting member is so supported on a frame as to be movable in the moving direction of the workpiece. The driving member causes the supporting member to reciprocate. The rotary member makes a pair of first pulleys rotate with movement of the supporting member, the first pulleys being rotatably supported with a predetermined spacing on said supporting member. The moving member is connected to a pair of second pulleys rotatably supported with a predetermined spacing on the supporting member. The speed change mechanism is connected at least between one of the first pulleys and one of the second pulleys and moves the moving member by rotating the second pulleys at a given rotational frequency with respect to the first pulleys which rotate with movement of the rotary member. The chuck member mounted on the moving member serves to chuck the workpiece. |
