Abstract
A feed wheel 10 provided at front and rear sides thereof with an intermittent gear 10b and a notched gear 10d, is formed on one end portion of a cylindrical cam shaft 5 for moving a printer, with a mesh-prevention side 10c left at its center. A switch cam 11 for moving a ribbon cassette upwardly and downwardly is integrally formed on one end portion of a guide shaft 4 of the printer. A notched pinion 9 having a feed gear 9a and an intermittent feed gear 9b arranged alternately on its peripherals surface is also slidably mounted on the end portion of the guide shaft 4. When the printer is moved to a two-color shifting position in accordance with a program, the printer pushes the notched pinion 9 for movement against a compression spring 8, so that the intermittent feed gear 9b and the feed gear 9a of the notched pinion 9 is brought into mesh with the intermittent gear 10b and the notched gear 10d of the feed wheel 10, respectively, to rotate the notched pinion 9 in order to pivot a switch cam 11.
