STRIKING APPARATUS FOR ROTATING WHEEL PRINTER

摘要

Striking apparatus for a rotating wheel printer where the striking apparatus includes a hammer mounted on one end of a lever having an intermediate semicircular bearing portion mated with a pin where the bearing is maintained in engagement with the pin by a biasing spring. An exciter includes a ram for impacting against the lever to move the hammer into contact with the printing wheel, the ram extending from a disc of magnetic material which is normally retained in the rest position by a permanent magnet but is attracted by a cup-core type electromagnet for causing the exciter to impact the lever to rotate the hammer into contact with the printing wheel.
