    摘要: A reader for punched document cards having a slide for carrying a document card and movable manually against the action of a spring to put the document card in a pre-reading position, a governor for controlling the motion of the slide and document card in a return movement generated by the spring and a series of switches actuated by the punchings as the card returns under spring action to an initial position. One way clutch mechanism is associated with the governor so that the initial movement of the slide and document card may not be impeded by governor action. A latch operated by the slide is effective to prevent movement of the slide manually out of its initial position with no card in the reader, and the latch is negated in its action by a card in position so that the slide and card may be moved out of initial position.
