Patent number: 4227801Abstract: The machine, which may be a facsimile machine, stands on the floor and includes a roll of paper which runs over a stylus assembly, by means of which a pattern of electrostatic charges are formed on the paper, after which the paper is cut and fed downwardly toward the lower end of the machine where it is treated with toner, which is then fused to provide a fixed visible message thereon. The printed document is driven generally upwardly by a roller assembly onto a generally vertically oriented document-receiving tray which is elevated somewhat above the lowest level of the machine at a level which is comfortable for the operator. The tray has a V-shaped document-supporting base, and the apex of the V provides a ridge on which the documents are bent slightly to render them rigid and easy to stack. The roller assembly at the base of the tray is arranged to stiffen the document and facilitate its movement into the tray.Type: GrantFiled: March 19, 1979Date of Patent: October 14, 1980Assignee: Burroughs CorporationInventors: Douglas R.

Patent number: 4220978Abstract: The disclosure is of apparatus including a duct-like light guide having an inlet end and an outlet end, light source means at the inlet end, a document at the outlet end, an optical reading system for receiving light reflected from the document, and electronic circuit means for converting the reflected light to electrical signals. Typically, the optical reading system has non-uniform light transmission characteristics, and, with one type of lens system, there is fall-off in intensity at the ends of the system. To compensate for this fall-off, the light source means is designed and positioned to provide a corresponding non-uniform light distribution so that the net effect is a uniform light distribution at the output of the lens system.Type: GrantFiled: July 8, 1977Date of Patent: September 2, 1980Assignee: Burroughs CorporationInventors: Richard W.
