ABSTRACT:
Disclosed is a shuttle mechanism of a dot line printer including a printing shuttle unit making a reciprocating motion to perform dot printing and a balance shuttle unit making a motion in a direction opposite to the kinetic motion of the printing shuttle unit. This shuttle mechanism is constructed of a linear motor in which a movable unit for the reciprocating motion and a magnetic circuit are separated. With this construction, the movable unit can be decreased in weight. Therefore, the high-speed reciprocating motion can be made, and high-speed printing is thereby attainable. The balance shuttle unit is disposed under the printing shuttle unit. The apparatus can be thereby made compact.
