    • A system of mounting a raster output scanner relative to a photoreceptor such that deskewing, focusing, and pitch adjustment of the aerial image are possible. A spring isolated ROS assembly having at least two ROS arms attaches to a backer bar assembly that locates the position of the photoreceptor. The backer bar assembly and the ROS assembly connect at one end using a ball and socket and at the other end using a ball and fork such that the center line of the balls form a scan line plane. The ball and socket form a reference connection at one end. At the ball and socket end the photoreceptor backer bar has a mounting arm that is flexible in one plane but rigid in a perpendicular plane. A deskew mechanism, beneficially a motor driven cam, flexes the backer bar mounting arm as required to deskew the scan line.
    • 相对于感光体安装光栅输出扫描器的系统,使得可以进行空中图像的偏斜校正,聚焦和俯仰调节。 具有至少两个ROS臂的弹簧隔离的ROS组件连接到定位感光体的位置的支撑杆组件。 支撑杆组件和ROS组件在一端使用球窝连接,另一端使用球和叉连接,使得球的中心线形成扫描线平面。 球窝在一端形成参考连接。 在球窝端,感光器支撑杆具有一个安装臂,该安装臂在一个平面上是柔性的,但在垂直平面上是刚性的。 一种有利的电动机驱动凸轮的偏移机构根据需要使支撑杆安装臂弯曲以使扫描线偏斜。

    • This is a film image input system wherein an image of the developed still photo film is made to focus on an image sensing plane of a charge coupled device through a taking lens to be converted into electric signals and the electric signals are input in a video monitor. The film image input system comprises: a zoom driving part for changing the image magnification of the taking lens; a scan mechanism for moving an image taking positionon the film by the taking lens; and a control part for controlling the scan mechanism in such a manner that the moving speed of the scan mechanism is decreased with the increase in the image magnification of the taking lens and making the moving speed of a screen on the video monitor constant during scan. Furthermore, the control part can restrict the scan scope of the scan mechanism in accordance with the image magnification, satisfactorily display the scope being picked up at present on a display device, and return the scan position to the center of the film and return the image magnification to a predetermined standard magnification so that the film image in the whole frame can occupy the whole screen of the video monitor, upon receiving the standard reproduction command.
    • 这是一种电影图像输入系统,其中通过拍摄镜头将显影的静态摄影胶片的图像聚焦在电荷耦合器件的图像感测平面上,以转换成电信号,并将电信号输入到视频监视器 。 胶片图像输入系统包括:变焦驱动部分,用于改变拍摄镜头的图像放大率; 扫描机构,用于通过拍摄镜头移动胶片上的图像拍摄位置; 以及用于控制扫描机构的控制部件,使得扫描机构的移动速度随着拍摄镜头的图像放大率的增加而减小,并且使得视频监视器上的屏幕的移动速度在扫描期间恒定。 此外,控制部件可以根据图像放大率来限制扫描机构的扫描范围,令人满意地显示目前在显示装置上拾取的范围,并将扫描位置返回到胶片的中心并返回图像 放大到预定的标准放大率,使得在接收到标准再现命令时,整个帧中的胶片图像可以占据视频监视器的整个屏幕。

    • In an image input terminal for deriving an electronic representation of the image, including a platen for supporting a document to be scanned, a scanning system including an illumination source for illuminating a document supported on the platen, an array of photosensitive elements which produce an electrical response to sensed reflected light, an arrangement for directing light reflected from a document to the linear array, and an arrangement for providing relative motion in a slow scan direction between the linear array of photosensitive elements and the document, there is provided an arrangement for rotating the scanning system of photosensitive elements and an illumination source about a rotational axis, by an amount corresponding to detected skew of the image, so that, upon relative movement of the linear array of photosensitive elements and the document, the effects of skew in the slow scan direction are removed from the electronic representation of the image. The scanned image still contains a component of skew in the slow scan direction. Accordingly, each pixel is shifted in the fast scan direction by an amount corresponding to the position of the scan line with respect to a start of page signal.
