Abstract
A printer having an ink ribbon shift apparatus includes a carrier unit having a printer head and a ribbon guide which is movable upwardly and downwardly. Up and down shift means are provided to shift an ink ribbon cassette up and down. A shaft is disposed parallel to a platen and extends along the entire range of movement of the carrier unit. The shaft shifts up and down together with the ink ribbon cassette and is engaged with the said ribbon guide. The up and down shift means moves the ink ribbon cassette up and down and the ribbon guide is thereby shifted up and down via the shaft so that a predetermined color band of an ink ribbon is positioned on a printing line.
