    • The invention involves an internal drum thermal imaging apparatus comprising a support for supporting a receiver material and a donor material in a superimposed relationship. The support includes a cylindrical drum having an inner circumference on which the receiver material is supported against in a bottom layer of the superimposed relationship and the donor material in a top layer of the superimposed relationship. An imaging unit thermally transfers an image from the donor material to the receiver material. An applicator automatically loads and unloads the receiver material and the donor material onto the cylindrical drum comprising an applicator carriage, an attachment device for attaching the receiver material to the applicator and an applicator transport device for transporting the applicator carriage along the inner circumference of the cylindrical drum.
    • 本发明涉及一种内部鼓热成像设备,其包括用于以叠加关系支撑接收器材料和施主材料的支撑件。 支撑件包括具有内圆周的圆柱形滚筒,接收器材料在该内圆周上被支撑在叠加关系的底层中,并且施主材料位于叠加关系的顶层中。 成像单元将图像从施主材料热传递到接收器材料。 施加器自动地将接收器材料和施主材料装载和卸载到圆柱形滚筒上,该圆柱形滚筒包括施加器托架,用于将接收器材料附接到施加器的附接装置和用于沿着圆柱体的内圆周运送施用器托架的施用器运送装置 鼓。

    • A punch assembly is provided with a positive retraction mechanism to remove the punch from the media to be punched, thereby preventing binding of the punch in the media. The punch assembly includes a driving mechanism to provide a driving force on the punch and a positive retraction mechanism disposed to provide a retraction force on the punch operative sequentially following operation of the driving mechanism. The punch assembly, which is of a smaller size and more economical to manufacture, is particularly useful with an imagesetter of a prepress printing system. The punch may be mounted in a cantilever manner to punch the opening as close to the edge of the media as possible without interfering with the laser beam of the imaging assembly. In this maimer, the area of media available for imaging may be maximized and media waste minimized. Additionally, a shaft support mechanism is provided for the shaft upon which the retraction mechanism for each punch is mounted. When the punches advance into the media, an oppositely directed force is placed on the shaft. The shaft support mechanism supports the shaft when it is so loaded by the punches, thereby minimizing deflection of the shaft and allowing use of a smaller diameter shaft. Other equipment, such as take-up rollers which are used to transfer the media may also be fixed to the punch assembly. Similarly, a cutter assembly which cuts sheets of the media may also be fixed to the punch assembly.
    • 冲头组件设置有正退缩机构以从待冲压的介质上移除冲头,从而防止冲头在介质中的结合。 所述冲头组件包括用于在所述冲头上提供驱动力的驱动机构以及设置成在所述驱动机构的操作之后按顺序提供所述冲头上的缩回力的正退缩机构。 具有较小尺寸并且制造更经济的冲头组件对于印前打印系统的成像机特别有用。 冲头可以以悬臂方式安装,以尽可能靠近介质的边缘冲压开口,而不会干扰成像组件的激光束。 在这个迷雾中,可用于成像的介质面积可能最大化,并且媒体浪费减至最少。 此外,为轴安装轴支撑机构,每个冲头的退回机构安装在该轴上。 当冲头进入介质时,相反的力被放置在轴上。 轴支撑机构在通过冲头加载时支撑轴,从而最小化轴的偏转并允许使用较小直径的轴。 用于传送介质的诸如卷取辊的其它设备也可以固定到冲头组件。 类似地,切割介质片的切割器组件也可以固定到冲头组件。
