ABSTRACT:
An electrostatic document copying system which includes an electrostatic plain paper engineering copying machine having a copy paper feed rack secured thereto, and copy paper guide channels adjustably secured thereto in copy paper-receiving alignment with copy paper rolls supported on the feed rack. The copy paper feed rack includes a frame attachable to the copier, and carrying a plurality of cantilevered, telescoping copy paper roll-supporting arms. These arms are individually selectively extensible. They are arranged to cooperatively cradle and support a plurality of continuous copy paper rolls to facilitate simultaneous feeding of copy papers from multiple rolls. A plurality of original documents can thus be simultaneously copied. The apparatus is especially adapted for copying elongated oversized documents, such as oil well logs.
