摘要： A belt is rotated in the direction indicated by the arrow F by a motor to cause first and second feed roller pairs to feed a stimulable phosphor sheet in the direction indicated by the arrow X2. Before the stimulable phosphor sheet is scanned by a light beam, the belt is rotated a predetermined length in the direction indicated by the arrow E by the motor. Thereafter, the belt is rotated to cause the first and second feed roller pairs to feed the stimulable phosphor sheet in the auxiliary scanning direction indicated by the arrow X1. When the stimulable phosphor sheet is scanned by a light beam, the belt is stably held in a desired position on the driven pulley, but is not slid sideways, allowing the stimulable phosphor sheet to be fed highly accurately in the auxiliary scanning direction.

摘要： An image scanner utilizes an area CRT while avoiding the low linear resolution limitations of such a device. The CRT is coupled to a noncoherent fiber optic bundle (area array) having a proximal end of a geometry to optically match the scanned area of the face plate. The remote end of the fiber array is linear and coupled to a scan segment of a page to be scanned. The beam of the CRT is directed to the consecutive fibers of the bundle in a sequence imposed by a look-up table containing digital addresses and digital to analog converters to produce the required x-y deflection voltages. Since there need only be 5100 fibers for a 600 line per inch scanner and the spot resolution of the CRT need only be in excess of 5100 positions, the resolution is easily obtained. For example, 5100 spots implies a linear resolution of 72 elements in a scan line. The decay time of the phosphor is chosen to be short enough that only one fiber is illuminated at any instant. A single output photodetector is used for monochrome and a three output photodetector is used for color.
摘要翻译：图像扫描器利用区域CRT，同时避免这种装置的低线性分辨率限制。 CRT耦合到具有几何形状的近端的非相干光纤束（区域阵列）以光学地匹配面板的扫描区域。光纤阵列的远端是线性的，并且耦合到要扫描的页面的扫描段。 CRT的光束以包含数字地址和数模转换器的查找表强加的顺序被引导到束的连续光纤，以产生所需的x-y偏转电压。由于每英寸扫描仪只需要有5100根光纤，而CRT的光点分辨率只能超过5100个位置，所以分辨率很容易获得。例如，5100个点意味着扫描线中的72个元素的线性分辨率。荧光体的衰减时间被选择为足够短，以至于只有一根光纤在任何瞬间被照亮。单个输出光电检测器用于单色，三色输出光电检测器用于颜色。

摘要： A device providing high resolution readout of information stored on a film. A slit equal in width to the desired spot size diameter is placed in front of a moving film. A fiber optics strip is placed in back of the film in line with the slit. A beam of light scans across the slit. The fiber optics strip is comprised of a plurality of optic fibers. The width of each fiber is also equal to the desired spot size diameter. All of the optic fibers are connected to a small group of photodetectors.

摘要： A cathode ray tube provides a two-dimensional sequential scan pattern on which dots for scanning or printing are presented as spots of light provided in sequence. A single multi-scan linear raster sweep of the cathode ray tube electron beam produces a single line of dots on the scanned image or photosensitive medium. A fiber optics array with one end facing the cathode ray tube, is configured two-dimensionally in a pattern that corresponds to the sequential sweep pattern of the cathode ray tube. The trace of dots on the cathode ray tube has sufficient length to accommodate the number of dots required for the width of the finished product or scanned image. A lens positioned between the cathode ray tube and optical fiber array, focuses the cathode ray tube image onto the fiber ends with a reduction in size. At the other end of the fiber optics array, the fibers are abutted together linearly to form the desired final output line width with coherence of the fibers from input to output. The output line width can be any desired length by abutting more optical fibers and increasing the length of the cathode ray tube sweep. Individual "fibers" may be a sub-bundle including a cluster of small diameter fibers. The speed of the cathode ray tube sweep determines the speed of the printer or scanner.

摘要： A document scanner or printer includes a fiber optic bundle which has the fibers of one end arranged in a linear array and the fibers of the other end arranged in an area array. A CRT, or equivalent device, is coupled to the area array and adopted to generate light in a sequence of positions there. The sequence of positions is determined by an algorithm which organizes the addresses of those positions in a list of consecutive near neighbors. Other embodiments are operative to eliminate from the address sequence any address at which no light is to be generated. By shortening the path that a beam traverses or by eliminating some addresses from the address sequence, improved operating speeds are achieved.
