摘要 |
A ribbon feeding device for a printer, which is simple in structure and easy to assemble and in which engagement between a pinion supported on a carriage and a rack is maintained when the carriage for carrying a printing head moves toward and away from the rack without providing the rack with any engaging member. An arm is swingably supported on the carriage at one end thereof, and the pinion engaged with the rack and operatively connected with a transmission mechanism is rotatably supported on the other end of the arm. One end of a torsion coil spring for urging the pinion towards the rack is engaged with the arm and at the other end thereof is engaged with the carriage. In accordance with the movement of the carriage toward and away from the rack, the arm swings to keep the engagement between the pinion and the rack appropriately.
