A stored energy ejector mechanism is disclosed and described and includes an ejector plunger member which is propelled by a spring-bias induced by an actuator lever actuated by a stroke of a punch press and the like. The stored energy in these springs is released and the propelling or ejection motion of a plunger member is begun by the actuation of a trigger mechanism whose release time is selectively established and preferably occurs during the same stroke of the press mechanism in which is produced the loading of the springs. Although primarily for use with a punch press to provide a substantially quiet ejector action, this stored energy is equally applicable to other operations such as providing an ejector mechanism for use with a conveying or line inspection system employing linear motion.
