ABSTRACT:
The present invention describes linear reciprocating motion device comprising an object which is movable exclusively in a prescribed direction, a cam groove which is formed on a closed curve, a linking rod whose one end is connected to the object and its the other end is engaged with the cam groove, and methods for moving the other end of said linking rod along the cam groove with a prescribed angular velocity. The moving methods with angular velocity comprises a crank arm whose length is free to be increased or decreased, with its one end connected to the other end of the linking rod and rotates in the interior of the closed curve, and a motor that causes the crank sub-arm that is linked to the crank arm to rotate at a constant speed.
