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. The fibers and the detectors are arranged in such a manner that no one detector will receive information from more than one fiber at any one time as the beam scans across the slit.

摘要： A multiple resolution scanner device for scanning an object may comprise a first optical wave guide bundle having a light input end, a light output end, and a first reduction ratio associated therewith. The light input end of the first optical wave guide bundle is arranged to receive image light from the object being scanned. A second optical wave guide bundle having a light input end and a light output end has a second reduction ratio associated therewith that is different than the first reduction ratio associated with the first optical wave guide bundle. The light input end of the second optical wave guide bundle is arranged to receive image light from the object being scanned. A detector positioned adjacent the light output ends of the first and second optical wave guide bundles receives image light from the light output ends and produces an image data signal related to image light received from the light output ends. An optical wave guide selection apparatus operatively associated with the scanner device selects an optical wave guide bundle, the image light from which is used by the detector to produce the image data signal.

摘要： A media spacing system for a fiber optic CRT printer. The system has a film coating over the fiber optic portion of the CRT, outside the phosphor display area, which keeps the media a fixed distance from the display area to provide for a uniform display of data on the media. The film may be applied in multiple layers, with each successive layer having a larger size, to create a rounded edge for the coating. A pressure plate is placed on the opposite side of the media from the film coating to keep the media firmly against the film coating. A compliant element, such as foam rubber, attaches the pressure plate to a fixed bracket to allow the pressure plate to adjust for bow and twist of the CRT, while maintaining pressure against the media.
