Abstract

A ribbon feed mechanism for a printer which develops a drive force for a printing ribbon utilizing the reciprocating movement of a carriage. Torque is applied to two drive gears through a single wire under tension in response to the movement of the carriage. A ribbon drive gear for feeding the ribbon in a predetermined direction is alternately meshed with the two drive gears during reciprocation of the carriage to be thereby rotated in a predetermined single direction. When the ribbon feed is needless, the tension is removed from the wire.
