ABSTRACT:
An electronic inspection fixture is provided which checks a dimension of objects and rejects oversized ones. The inspection fixture includes spaced conducting members set apart at a fixed distance and preferably placed one above the other at angles to the horizontal which enables objects to slide between the members by gravity. An oversized object completes a circuit between the members and causes a fluid-operated cylinder to move the upper member away from the lower one to release the object. The circuit also operates a second fluid-operated cylinder which moves a diverter member into the path of the objects to divert oversized objects from the normal path thereof. Objects which are not oversized pass between the members and past the diverter member.
