Abstract
A drive mechanism for printer carriage and printing ribbon includes a roller for feeding an ink ribbon, a shaft rotatably mounted on the printing carriage, first and second pulleys rotatably mounted on the shaft, first and second one-way clutches for transmitting the rotation of the first and second pulleys in a predetermined direction to the shaft, a cord stretched on the first and second pulleys so as to cause translational movement of the shaft and first and second pulleys in first and second directions. In this drive mechanism, the pulleys are respectively rotated in opposite directions when they are translationally moved in the first or second direction. The rotation of these pulleys in a predetermined direction is transmitted through the first and second one-way clutches to the shaft, and the rotation thereof is transmitted through a coupler to the ink ribbon feed roller.
