摘要： A printing device comprising a motor (6); a drive mechanism (8c, 9, 10, 11a) for alternately transmitting drive from the motor (6) to first and second output members (21, 11); type means (50-53) arranged to be driven by the first output member (21) so that selected type (50a, 51a, 52a) can be brought to a printing position; and a printing mechanism (55) arranged to be driven by the said second output member (11) so as to engage the type means (50, 53) to effect printing of the said selected type on a sheet (45), characterised by a locking member (12) for alternately arresting and locking the first and second output members (21, 11); an electromagnetically operated trigger member (23) for causing the locking member (12) to release the second output member (11) and to arrest and lock the first output member (21); and a return drive member (11d) driven by the second output member (11) for causing the locking member (12) to release the first output member (21) and to arrest and lock the second output member (11).

摘要： An impact printer is provided with a print member which comprises a first helical element (11) having a first font of type characters arranged around its periphery; this first helical element is rotatably mounted so as to be linearily movable along an axis adjacent to a print medium. The print member further includes a second helical element (12) having a second font of type characters arranged around its periphery, and this second helical element is rotatably mounted along the same axis in a position interspaced with the first helical element so as to be rotatable and linearily movable along the axis independent of the first helical element. The print member further includes means (20, 21, 17, 22) for rotating the first and second helical elements.
