Abstract
A printer includes a print head moving in printing and shifting regions, a carriage connecting the print head and the print head transport mechanism, and a ribbon cassette mounting mechanism that drives a multicolor ribbon cassette to swing. A ribbon cassette supporting mechanism in the shifting region correspondingly supports the ribbon cassette mounting mechanism to different levels to shift color of the ink ribbon while the ribbon cassette supporting mechanism rotates. A ribbon cassette shifting mechanism fixed on the carriage is used, in the shifting region, to lift the ribbon cassette mounting mechanism to a position disengaged from the ribbon cassette supporting mechanism and move the ribbon cassette supporting mechanism to rotate. A resetting mechanism fixed on the ribbon cassette supporting mechanism resets the ribbon cassette supporting mechanism when the ribbon cassette supporting mechanism no longer contacts the ribbon cassette mounting mechanism and the ribbon cassette shifting mechanism.
