PURPOSE:To carry out automatic change of an oscillation stroke of an eccentric cam and accurate positioning of a table, by disposing a clutch mechanism for making connection and release of an eccentric cam. CONSTITUTION:With regard to the changing operation of an oscillation stroke of an eccentric cam plate 15, electric charging of a clutch 19 is stopped by operation of an operation pannel and a cam shaft 11b and a reciprocation shaft are rotated by the operation of a servo-motor 13 by an eccentric angle to obtain a desired eccentric stroke according to a table of eccentric angle- eccentric stroke inputted preliminarily in a control device. Then, an electric charging is carried out to the clutch 19 by operation of the operation pannel and the cam shaft 11b and the eccentric cam plate 15 are connected to each other to obtain a desired stroke. |
