    • A document scanner includes: a document support for supporting a document in position to be scanned; an illumination system located adjacent to the document support for illuminating at least a portion of a supported document; a photosensitive medium for capturing an image of the document and generating image information; and a retroreflective imaging lens having an F-number between F/3 and F/8. The retroreflective lens comprises at least one lens element with optical power and a reflective surface, and is positioned to (i) receive light emanating from the document and propagated it in a first direction, through the retroreflective lens, (ii) reflect the light off said reflective surface in a second direction, and (iii) propagate the light through the retroreflective lens in the second direction, towards the photosensitive medium. The document support, the photosensitive medium, and the retroreflective lens are in a fixed spatial relationship relative to one another. According to one embodiment of the present invention the illumination system provides less than 1 watt of power.
    • 文档扫描器包括:用于支持要扫描的位置的文档的文档支持件; 照明系统,位于所述文件支撑件附近,用于照亮被支撑文件的至少一部分; 用于捕获文档的图像并产生图像信息的光敏介质; 以及F / 3和F / 8之间的F数的回射成像透镜。 回射透镜包括具有光焦度和反射表面的至少一个透镜元件,并且被定位成(i)接收从文件发出的光,并沿着第一方向通过回射透镜传播它,(ii)反射光 所述反射表面在第二方向上,以及(iii)将所述光沿所述第二方向传播通过所述回射透镜朝向所述光敏介质。 原稿支撑件,感光介质和回射透镜相对于彼此处于固定的空间关系。 根据本发明的一个实施例,照明系统提供小于1瓦的功率。

    • A film cassette comprises a spool supported within a cassette shell for rotation about an axis to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is only partly exposed, and a film exposure status indicator supported for rotation within the shell about the axis from an unexposed position to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. According to the invention, the spool and the status indicator are fixed coaxially to each other. The spool has three spaced detents arranged at separate locations for respective engagement to lock the indicator in its unexposed, partly exposed and fully exposed positions. The shell has an end cap including a locking pawl normally urged to individually engage any one of the detents, but which can be moved to disengage any one of the detents by a suitable device in a camera.
    • 胶卷盒包括支撑在盒壳内的卷轴,用于围绕轴线旋转,以将卷绕在卷轴外部的胶片推到外壳的外部,无论胶片是否未曝光或仅部分曝光,以及胶片曝光状态指示器,用于旋转 在壳体内围绕轴线从未曝光位置到相应的部分暴露和完全暴露位置,以提供可见的指示,即胶片仅部分地暴露或基本上暴露。 根据本发明,线轴和状态指示器彼此同轴地固定。 阀芯具有三个间隔的止动件,其布置在分开的位置处,用于相应的接合以将指示器锁定在其未曝光,部分暴露和完全暴露的位置。 壳体具有端盖,该端盖包括通常被推动以单独地接合任何一个棘爪的锁定爪,但是可以通过照相机中的合适装置移动以使脱离任何一个棘爪脱离。

    • A light tight cartridge for a roll of web material (32) comprises a can (40), which contains the roll of web material (32). A first protrusion (52) on the can (40) rotatably supports the roll of web material (32). A cover (42) fits over the can (40) in a light tight fashion. A second protrusion (52) rotatably supports the roll of web material (32). In one embodiment, light blocking material is provided at a slot (44) in the can (40) and at a cover extension (48) to prevent light leaks into the cartridge (30). In another embodiment of the invention, the cover (42) is ultrasonically welded to the can (40).
    • 用于卷材材料卷(32)的不透光筒包括容纳卷材(32)的卷筒(40)。 罐(40)上的第一突起(52)可旋转地支撑卷筒纸材料卷(32)。 盖(42)以不透光的方式装在罐(40)上。 第二突起(52)可旋转地支撑卷筒纸材料卷(32)。 在一个实施例中,遮光材料设置在罐(40)中的狭槽(44)处和盖延伸部(48)处,以防止光泄漏到盒(30)中。 在本发明的另一个实施例中,盖(42)被超声波焊接到罐(40)上。

    • A disk cassette loading/unloading mechanism for use in a disk recorder or the like of the type having a disk drive mechanism comprises a pivotally mounted holder for holding a disk cassette. The holder is pivotally movable between a loading/unloading position in which a disk cassette is inserted into the holder to its loaded position and unloaded therefrom, and a recording position in which the disk in the disk cassette can be drivingly engaged by the disk drive mechanism. Insertion of a disk cassette into the holder to its loaded position automatically activates a rigid cassette shutter opening device to open the shutter, and causes the holder to move from its loading/unloading position into its recording position. The holder is moved by a cassette ejecting mechanism from its recording position to its loading/unloading position. The ejecting mechanism then ejects the disk cassette at least partially out of the holder.
    • 用于具有盘驱动机构的盘式记录器等的盘盒装载/卸载机构包括用于保持盘盒的可枢转地安装的保持器。 保持器可在其中将盘盒插入保持器到其装载位置并从其中卸载的装载/卸载位置之间枢转运动;以及记录位置,盘盒中的盘可以由盘驱动机构驱动地接合 。 将磁盘盒插入保持器到其装载位置,自动启动刚性的盒式磁带开启装置以打开快门,并使保持器从其装载/卸载位置移动到其记录位置。 保持器通过盒式弹出机构从其记录位置移动到其装载/卸载位置。 然后,排出机构至少部分地从保持器中弹出盘盒。
