A press machine includes: an electric motor ( 19 ) for raising and lowering a slide ( 11 ) by rotating a crank shaft ( 13 ); motion datum receiving means ( 29 ) through which, by an input operation, an operator inputs a motion datum including, as input items, height positions at which the slide ( 11 ) starts and ends an oscillation process, a speed at which the slide ( 11 ) carries out the oscillation process, an angle at which the crank shaft ( 13 ) is rotated in a direction during a drive-in operation, and an angle at which the crank shaft ( 13 ) is rotated in the other direction during a return operation; motion pattern generating means ( 63 ) for generating a motion pattern of the slide ( 11 ) on the basis of the motion datum inputted through the motion datum receiving means ( 29 ); and motor controlling means ( 73 ) for controlling the electric motor ( 19 ) on the basis of the motion pattern generated by the generating means ( 63 ).
