    摘要: The key depression touch of a key-actuated business machine is controlled by adjusting the position of a spring bail which simultaneously controls the tension of all the key lever springs. A manually positioned control member with attendant linkages positions the spring bail and simultaneously adjusts the tension of counterbalancing spring means to minimize the unbalanced spring forces acting on the spring bail and the entire touch control system at all touch settings of the touch control apparatus.
