Abstract
Abstract An apparatus which includes a feeding device for feeding a document onto a document platen on which the document is irradiated by a light source to obtain a copy image and a discharging device for discharging the irradiated document from the document platen. The apparatus includes a housing unit shaped in the form of a plate for covering the document platen; a hinge for pivotally mounting the housing unit on the document platen, and first, second and third sub-housings made to protrude upwards from the top surface of the housing unit. The first sub-housing is disposed on one side of the housing unit and incorporates the feeding device. The second sub-housing is disposed on the opposite side to the one side and incorporates the discharging device. The third sub-housing is disposed on a side between the one side and the opposite side and incorporates both the hinge and driving mechanism for both the feeding device and the discharging device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
An apparatus for feeding documents across a platen and receiving documents discharged from the platen, said apparatus comprising: a housing unit pivotally attached at a first side edge to cover the platen and having an opposite second side edge, said housing unit including a planar surface portion, and having first, second, and third sub-housing portions with outer and inner walls of a predetermined height, said inner walls defining a portion of the perimeter of the planar surface portion of the housing unit for supporting discharged documents, said planar surface portion extending to and including the opposite second side edge so as to permit removal of discharged documents in a direction parallel to said planar surface portion; means disposed in said first sub-housing portion for feeding documents to the platen; means disposed in said second sub-housing portion for discharging documents from the platen; and means disposed in said third sub-housing portion for driving said feeding means and said discharging means.
