Abstract
A printer is disclosed which comprises a type platen and a type head opposite the periphery of said type platen and spaced apart therefrom to form a given gap spacing therewith. The type head is located in a plane extending perpendicular to the axis of the type platen and is movable in a direction parallel to the axis of the platen. The typehead includes a plurality of impacting wires arranged radially about the axis of said type platen, a plurality of operating pins each secured to the rear end of each of the impacting wires, and a plurality of solenoids having corresponding armatures whose free ends are adapted to be engaged with the operating pins when the solenoids are energized in response to given print signals, the front ends of the impacting wires are caused to impact upon the peripheral surface of said type platen to imprint characters corresponding to these signals on a record sheet.
