摘要： A closure mechanism for hinged devices having an upper member and a lower member. The closure mechanism includes a track disposed on the upper member and at least one support arm pivotally attached to the lower member. A biasing element is adapted to urge the support arm to engage the upper member and urge it to pivot to an open configuration. The arm includes a contact element that engages the track such that an upper end of the arm moves along the track as the upper member pivots to an open position. The arm includes a hook that engages a positive stop to prevent over-rotation of the arm. In other embodiments of the closure mechanism, the arm is pivotally attached to the upper member and moves against the lower member, and the biasing element extends between the arm and either the upper member or the lower member.

摘要： A maintenance station for an ink jet printer comprises two modules supported from the printer middle frame by a tongue and groove arrangement and secured in place only by retaining elements integrally formed with the middle frame. The first module includes a wiper element and a cap to provide an air seal around the nozzles. The wiper and cap are mounted on a pivoted rocker element so that as the wiper is moved toward the printhead the cap is moved away therefrom and visa-versa. The second module carries a small DC motor, a nut with a pair of forked arms, and gearing for converting bidirectional rotation of the motor into linear reciprocal motion of the forked arms. The forked arms engage projections on the rocker element so that the wiper or cap is moved toward or away from the printhead depending on the direction of rotation of the motor. In a first position of the rocker element the wiper is positioned in the path of the printhead so as to wipe the nozzles as the printhead is moved back and forth. In a second position the cap presses against the printhead to form an air seal around the nozzles. In a third position the wiper and cap are both spaced away from the path of the printhead and below the plane of the record feed path. The printer controller senses motor current and controls positioning of the rocker element without the need for a position feedback encoder.

摘要： A wiper for an ink jet printhead comprises a monolithic body having a mounting portion and a head portion, the head portion including a wiper portion and a beam portion for supporting the wiper portion on the mounting portion. The mounting portion has a bottom surface and a slot centered in the bottom surface where the slot extends toward the head portion from the bottom surface and receives a mounting beam that is movable. The wiper is characterized in that the wiper portion has two non-parallel side surfaces which diverge from the beam portion and intersect a flat top surface of the wiper portion at acute angles so as to form two parallel wiping edges which may alternately wipe the printhead as the printhead moves back and forth relative to the wiper. Because the side surfaces of the head portion form angles of less than 90.degree. with the top surface there is less tendency for the head to trap and ride on ink wiped from the printhead. The beam portion has a hole extending through it thus making it more flexible. This permits a harder material to be used in the wiper without causing damage to the printhead. The wiper is normally supported on the opposite side of the plane of record feed from the printhead and may be raised into the path of travel of the printhead. An optional blotter may be provided for absorbing from the wiper the ink which is wiped from the printhead.
摘要翻译： 用于喷墨打印头的擦拭器包括具有安装部分和头部部分的整体式主体，头部包括擦拭器部分和用于在安装部分上支撑擦拭器部分的梁部分。 安装部分具有底表面和在底表面中心的槽，其中槽从底表面朝向头部延伸并且接收可移动的安装梁。 擦拭器的特征在于，擦拭器部分具有两个非平行的侧表面，该两个非平行的侧表面与梁部分分开并且以锐角与擦拭器部分的平坦顶表面相交，以便形成两个平行的擦拭边缘，其可以交替地将打印头擦拭为 打印头相对于刮水器来回移动。 由于头部的侧面与顶面形成小于90°的角度，所以头部不易陷入并骑在从打印头擦拭的墨水上的倾向较小。 梁部分具有延伸通过它的孔，使得其更加柔性。 这允许在擦拭器中使用更硬的材料而不会损坏打印头。 擦拭器通常被支撑在来自打印头的记录进给平面的相反侧上，并且可以被升高到打印头的行进路径中。 可以提供可选的吸墨纸，用于从擦拭器吸收从打印头擦去的墨水。

摘要： The printhead of an ink jet printer is mounted on a printhead carrier for reciprocal movement on a carrier guide rod above a record feed path. A bi-directional motor drives a drive belt attached to the carrier to thereby pull the printhead back and forth. The belt is attached to the carrier at two points which are spaced from the axis of the carrier guide rod, one point being above the axis and the other point being below the axis. The arrangement is such that any tilt of the printhead carrier in a vertical plane, resulting from a pulling force of the drive belt, is always in the same direction regardless of the direction in which the printhead carrier is pulled. This improves the accuracy of ink dot placement thereby giving better print quality. The drive belt is mounted on pulleys which are positioned such that there is an upward incline from each attachment point to a pulley. The carrier is provided with feet which ride in a groove in a carrier guide. When the belt is driven, an upward component of force is applied to the carrier at the point where the belt is attached to the carrier. This upward force tends to rotate the printhead carrier about the guide rod, thereby forcing the carrier feet into engagement with the groove in the carrier guide. This reduces the tendency of the carrier to rotate in a horizontal plane as a pulling force is applied to it.
摘要翻译： 喷墨打印机的打印头安装在打印头支架上，用于在记录馈送路径上方的托架引导杆上往复运动。 双向电动机驱动附接到载体的传动带，从而来回拉动打印头。 皮带在与载体导杆的轴线间隔开的两个点处附接到载体，一个点在轴线上方，另一个点在轴线下方。 该布置使得不管打印头托架被拉动的方向如何，打印头托架在垂直平面中由驱动带的拉力产生的任何倾斜总是处于相同的方向。 这提高了墨点布置的精度，从而提供更好的打印质量。 驱动带安装在滑轮上，滑轮被定位成使得从每个附接点到滑轮有向上的倾斜。 托架上设置有脚架，它们搭载在托架导轨的槽中。 当带被驱动时，在皮带附接到载体上的位置处，向载体施加向上分力。 该向上的力趋向于使打印头托架围绕导杆旋转，从而迫使托架脚与托架引导件中的凹槽接合。 这降低了当施加拉力时载体在水平面内旋转的趋势。
