    • A beam alignment chamber comprising: a base, first and second side walls connected to the base, and a front wall located at the front edge of the base having an output opening. The beam alignment chamber further including a plurality of light sources disposed to direct light beams through the first or second side walls, a plurality of reflectors mounted on the base, each having independent yaw and pitch adjustments, each being disposed to direct the light beams from a corresponding light sources along the length of the beam alignment chamber through the output opening forming an aligned array of parallel light beams, and one or more optical elements positioned in the optical path of the aligned array of light beams disposed to correct the beam divergence with respect to at least one axis.

    • A print guide mechanism having parallel first and second guide rods, and a carriage assembly designed to move along the guide rods. The carriage assembly in a preferred embodiment comprises a frame and at least one pair of associated roller bearing assemblies being secured to the frame and being arranged so as to engage the first guide support rod for providing linear movement of the carriage assembly along the first guide rod, at least one upper roller bearing assembly mounted to the frame for engagement with the second guide rod, and a first mounting assembly having at least one lower roller bearing assembly. The at least one upper and lower roller bearing assemblies are arranged so as to engage the second guide rod between. The first mounting assembly is pivotally mounted to the frame so as to compensate for parallel misalignment between the guide rods and is biased for applying a loading force so that positive engagement is provided between the guide rods and the roller bearing assemblies. In the preferred embodiment at least one of the roller bearing assemblies having an outer engaging surface made of a material having a modulus of elasticity less than the modulus of the guide rod which it engages.
    • 具有平行的第一和第二导向杆的打印引导机构和设计成沿着导杆移动的托架组件。 在优选实施例中的托架组件包括框架和至少一对相关联的滚子轴承组件,其固定到框架并且被布置成与第一引导支撑杆接合,用于提供托架组件沿着第一导杆的线性运动 至少一个上滚子轴承组件安装到框架上用于与第二导杆接合,以及具有至少一个下滚子轴承组件的第一安装组件。 所述至少一个上滚子轴承组件和下滚子轴承组件布置成与第二导向杆接合。 第一安装组件枢转地安装到框架上,以便补偿导杆之间的平行不对准,并且被偏压以施加加载力,使得在导杆和滚子轴承组件之间提供正接合。 在优选实施例中,至少一个滚柱轴承组件具有由弹性模量小于其接合的导杆的模量的材料制成的外接合表面。
