    • A shuttle apparatus for a printer having a print shuttle unit driven to reciprocate. The print shuttle unit includes a print shuttle provided with a print head and movable along a guide device. A row of permanent magnets are attached to the print shuttle, and a row of electromagnetic coils are secured to a stationary member so as to face the permanent magnets across a gap. The coils and the permanent magnets constitute a linear motor for reciprocating the print shuttle unit along the guide device. A balance shuttle unit having approximately the same weight as that of the print shuttle unit is disposed so that the center of gravity of the balance shuttle unit travels on a line approximately the same as the line of travel of the center of gravity of the print shuttle unit. The balance shuttle unit is driven to reciprocate in linked relation to the print shuttle unit in parallel but reverse in direction to the print shuttle unit.

    • 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.
    • 公开了一种点阵式打印机的梭式机构,其包括进行点印的往复运动的打印往复单元和在与打印往复单元的运动方向相反的方向上进行运动的平衡梭单元。 该往复机构由直线电动机构成,其中往复运动的可移动单元和磁路分离。 利用这种结构,可以减小可动单元的重量。 因此,可以进行高速往复运动,从而可以实现高速打印。 平衡梭单元设置在打印梭单元下方。 因此,可以使该装置紧凑。
