PROBLEM TO BE SOLVED: To provide a reciprocating device capable of shortening a reciprocation cycle time by a high-speed reciprocation, securing a large reciprocation quantity by expansion and shrinkage caused by the reciprocation in operation, and mitigating the limitation on an installation space by shrinkage in length and miniaturization in operation stop. SOLUTION: This reciprocating device is provided with a fixed beam 1, a first moving beam 2 reciprocatably assembled to the fixed beam 1, a second moving beam 4 reciprocatably assembled to the first moving beam 2, and a drive source comprising a linear servo motor reciprocating the first moving beam 2. The reciprocation quantity of the second moving beam 4 is made larger than the reciprocation quantity of the first moving beam 2, and the reciprocating speed of the second moving beam 4 is made larger than the reciprocating speed of the first moving beam 2 by an augmenting/accelerating mechanism 5 having pulleys 5A and 5B and a timing belt 5D.
