Abstract
Line printer having a plurality of rotatable printing rings coaxially arranged adjacent each other and carrying on the peripheries thereof a plurality of characters for the printing and a movable roller pad adapted to abut against the printing rings at the predetermined printing position so that the selected characters of the printing rings held at the printing position are simultaneously printed on a paper held between the printing rings and the roller pad so as to form simultaneously a line of printing thereon in each printing cycle. The printing rings are rotated in the same direction in each printing cycle in order to eliminate a complicated mechanism for reciprocally driving the printing rings. The selection of the characters, temporary arresting of the same at the printing position and the printing operation by the roller pad are effected during a first half cycle of each printing cycle while the paper feeding and the releasing of the characters from the printing position are effected during the last half cycle of each printing cycle by way of a single common driving shaft.
