摘要： In a scanning unit such as a facsimile machine, an automatic document feeder transports individual sheets from a stack of documents along a document path over a scanning window to an output tray. An upper guide member includes an integrated chassis which provides most of the functional features required for picking individual sheets from a stack of documents in an input tray and transporting the sheet past a scanning window. The various components incorporated in the integrated chassis include a document separation mechanism, pre-scanning pinch rollers, post-scanning pinch rollers, a spring-loaded limiter with minimal paper path obstruction, a hinging mechanism to facilitate manual access to the document path, a latching mechanism, referencing datums, and ESD grounding including ESD brushes adjacent the document path and an ESD shield for a circuit board housed in the upper guide member. In the preferred form, the integrated chassis is formed from an enlarged sheet metal plate which attaches to the underside of a manual control/display panel with the circuit board sandwiched therebetween.

摘要： In a scanning unit such as a facsimile machine, an automatic document feeder transports individual sheets from a stack of documents along a document path over a scanning window to an output tray. Precise co-planar referencing is provided between a pick roller mounted on a frame beneath a document path and a document separator mechanism mounted on an upper guide member which moves between an open position for allowing manual access to the document path to a closed position for scanning document sheets. An integrated sheet metal chassis on the upper guide member provides a direct reference path between a central portion of the chassis which carries the document separator mechanism as well as Z axis and Y-axis (media transport direction) reference datums on both side edges of the channels which are engaged by a rigid vertical reference arm. A latching device is located closely adjacent to the reference datums to securely hold the upper guide member in a predetermined closed position, as well as determine positioning in the X axis. A pair of pivotal arms at the post-scanning end of the chassis allow clearance in the X-axis and Y-axis while providing secondary referencing in the Z-axis.
