PURPOSE:To simplify a feed mechanism in structure and control as well as to make its feed pitch variable, by guiding a reciprocatory main moving body, a constant pitch feed device of the stopper attached to the former and a moved body, and making each of them clampable to this guide device. CONSTITUTION:A moving table 7 is first reciprocated between a zero position and a stopper block 8, and its moving stroke is able to make it shorter or longer in order by one moving stroke of a constant pitch feed part 11. And, the moving table 7 is moved in following the stopper block 8 to be moved by one moving stroke of the constant pitch feed part 11 whereby the moving table 7 can be made to move by the one moving stroke of the constant pitch feed part 11. And, a travel of the moving table 7 can be optionally set by adjustment at the time of making arrangement, etc., of the moving stroke of the constant pitch feed part 11. |
