Ribbon drive coupling and cartridge tilt arrangement for print line visibility

摘要

A ribbon cartridge (10) is attached to a carrier (1) of a printing device such that it is tiltable along an axis that is parallel to the print line to drop the ribbon such that the print line is visible. That part of cartridge (10) which is opposite of the ribbon exposing part and on the other side of tilting axis (18) is on its bottom provided with a ribbon advance knob (8). Into this knob (8) two essentially upright standing walls and inclined ramps (11) are molded. The ribbon feed device (6), provided on carrier (1), has a blade (5) or noses (17) which cooperate with slot-forming walls (12) of knob (8). In ribbon drive direction (14) cartridge (10) automatically drops into coupling interconnection for ribbon feed. Upon turning ribbon feed device (6) in reverse direction (16) blade (5) or noses (17) slide up ramp (11) and lift the rear part and drop the front part of the cartridge (10) so that the print line is rendered visible.
