    摘要： A drive roller for an ink-jet printer. The drive roller has a media engaging surface that is roughened by grit blasting along an entire media engaging longitudinal peripheral extent. The surface is hardened by anodizing. The roller is relatively inexpensive to fabricate yet has a small error on diameter and run out, and high traction due to the surface roughness, to provide highly accurate media positioning performance. The drive roller rotates about shaft mounted bearings. The shaft journal is formed with a small raised bump, which has very loose diametrical tolerance requirements, but is short in comparison to the bearing length dimension. When the bearing is press fit onto the shaft journal, the material forming the raised bump is sheared by the bearing. The sheared material drops into a recess on the journal, and does not interfere with the axial positioning of the bearing. The axial position of the bearing is controlled by placing the bearing next to a shoulder formed on the shaft.

    摘要翻译： 用于喷墨打印机的驱动辊。 驱动辊具有介质接合表面，该介质接合表面通过沿着与介质接合的整个纵向周边范围的喷砂而被粗糙化。 表面通过阳极氧化硬化。 该辊制造相对便宜，但其直径和径向误差很小，并且由于表面粗糙度而具有高牵引力，以提供高度准确的介质定位性能。 驱动辊围绕轴安装的轴承旋转。 轴颈形成一个小凸起的凸起，其具有非常宽松的直径公差要求，但与轴承长度尺寸相比较短。 当轴承压配到轴颈上时，形成凸起凸起的材料被轴承剪切。 被剪切的材料落入轴颈上的凹槽中，并且不会干涉轴承的轴向定位。 通过将轴承放置在轴上形成的肩部附近来控制轴承的轴向位置。

    摘要： Continuous photo film (11) includes a support (11a) of resin film having a back surface. A photosensitive layer (11b) of photographic emulsion is disposed on a surface of the support opposite to the back surface. A conveying roller conveys the continuous photo film. The conveying roller includes a roller body (31) of metal. A hardness reinforcer layer (32) is formed on a surface of the roller body by thermal spraying and from ceramic or cermet, and avoids being scratched or ground by the back surface.

    摘要： A roller (10) over which advances a web of material (11) such as paper, photographic film or the like includes a plurality of staves (24,26) organized in first and second arrays with the staves of the first array alternating with the staves of the second array to provide surfaces for supporting the web. The staves are each individually mounted on the roller by separate spring legs (66) which center the staves. Flanges (14,16) are located at the ends of the roller to position the web laterally. When the web obliquely approaches the axis of the roller so as to helically advance thereover, the staves sequentially and independently shift axially due to engagement with the helically advancing web. After the web leaves the roller, the stave that the web was most recently supported by returns under the bias of the spring legs to its central, unbiased position. In this way, damage to the edges of the web, due to engagement with the flanges, is minimized.
