Abstract
The present invention relates to a ribbon guide assembly for a printer. A ribbon guide assembly (40) includes a ribbon guide (50) and a guide support (45). The ribbon guide (50) is employed on a replaceable printer ribbon cartridge to guide an exposed print section of a print ribbon (64) over a print head (80) of the printer. The ribbon guide (50) of the present invention has four members (56, 58, 60, 62) disposed between a bottom platform (52) and a top platform (54), whereby the members define a path for the print ribbon. The ribbon guide also has two collars (66, 68) coupled to the bottom platform and two of the members. Each of the collars defines a substantially circular opening. The guide support (45), affixed to the print head carriage, has two cylindrical alignment rods (90, 92) extending upward substantially perpendicular from the path of the carriage. The alignment rods (90, 92) of the print head are adapted to be inserted through the openings defined by the collars ( 66, 68) of the ribbon guide to securely support the ribbon guide.
