Abstract
A corona wire cleaning device for a corona unit for cleaning corona wires stretched in a shield case, comprising: a driving wire wound on a driving pulley and an idle pulley for reciprocating motion along the length of the corona wire; and a cleaning member slidably mounted in the shield case for traveling motion in association with the reciprocating motion of the driving wire and having a cleaning tool which rubs and cleans the corona wire by the traveling motion thereof in one direction and which comes away from the corona wire by the traveling motion thereof in the other direction, whereby a foreign matter such as dust can be surely removed from the corona wire, thereby accomplishing reliable cleaning of the corona wire.
