    • A microfiche reader includes an automatic motor driven retriever mechanism and a manual retriever mechanism. The manual retriever includes a guide having a transverse slot, a lever handle having a longitudinal slot and a pivot member slideable along the slots and supporting the lever for swinging between retracted and extended positions. A film carrier carriage is moveable along orthogonally related directions and is releasably couplable to the lever when the carriage is in a retracted rest position, the lever being locked to the carriage when the carriage is displaced from its rest position. The lever is locked in an inoperative condition when retracted and with the carriage displaced from rest position. A mechanism is provided for uncoupling the motors from the carriage or the carriages are coupled to the motors by slip transmissions or a switch is provided for deenergizing the automatic retriever mechanisms when the manual lever is in an operative position.
    • 微缩胶片读取器包括自动电机驱动的检索机构和手动检索机构。 手动检索器包括具有横向狭槽的引导件,具有纵向槽的杠杆手柄和可沿着槽滑动的枢转构件,并且支撑杠杆以在缩回位置和伸出位置之间摆动。 胶片承载架可沿着垂直相关的方向移动,并且当滑架处于缩回的停止位置时可释放地联接到杠杆,当滑架从其静止位置移位时,该杆被锁定到滑架。 当收回时,杠杆被锁定在不工作状态,并且滑架从静止位置移开。 提供了一种用于将马达与滑架分离的机构,或者滑架通过滑动传动联接到马达,或者当手动杆处于操作位置时提供用于断电自动回程机构的开关。

    • A film carrier device for a microfilm reader includes a rectangular transparent flat base plate having a pair of laterally spaced parallel longitudinally extending guide members located along opposite side top borders of the base plate. The rear inside faces of the guide members diverge rearwardly and have longitudinal grooves extending for the full lengths of their bottoms and the grooves may extend likewise for the full lengths of the guide member inside faces. A transparent cover plate is hinged along its forward edge to the forward border of the base plate and is swingable between a closed position overlying the base plate and a rearwardly upwardly inclined open position. A pair of laterally spaced film stops project upwardly from the base plate proximate its rear portions and a pair of leaf spring film engaging clips are disposed proximate the guide member front ends or proximate the film stops. Openings are formed in the cover plate to register with the stops and film clips when the cover plate is in closed position.
    • 用于微缩胶片读取器的胶片载体装置包括矩形透明平板底板,其具有沿着基板的相对侧顶边界定位的一对侧向间隔开的平行纵向延伸的导向件。 引导构件的后内表面向后发散,并且具有为其底部全长延伸的纵向凹槽,并且凹槽可以同样地延伸到引导构件内表面的整个长度。 透明盖板沿其前边缘铰接到基板的前边缘,并且能够在覆盖基板的关闭位置和向后向上倾斜的打开位置之间摆动。 一对横向间隔开的薄膜止动件在靠近其后部的位置从基板向上突出,并且一对薄片弹簧薄膜接合夹被设置在引导构件前端附近或靠近薄膜止动件。 当盖板处于关闭位置时,在盖板上形成开口以与止挡件和胶片夹对准。
