ABSTRACT:
An actuator including a solenoid and a "U"-shaped leaf spring. One end of the leaf spring is fixed to one end of the solenoid and the other end (a free end) of the leaf spring is located near the opposite end of the solenoid and is free to be attracted to the opposite end of the solenoid when it is energized. An actuating element is fixed to the free end of the leaf spring and is brought into operative engagement with a record medium when the actuator is actuated. A plurality of the actuators are arranged in a circle in a frame to produce a print head of the wire matrix variety. The actuators can also be used to punch holes in a record medium.
