Header sheet for image communications system
First Claim
Patent Images
1. A document header sheet for an image communication transmission system having means for scanning successive document sheets in a raster of successive spaced substantially parallel lines, said header sheet having:
- (a) a peripheral border, said border having a similar marking pattern along each edge of the sheet identifying said sheet as a header sheet when scanned by said scanning means, and variations in said pattern to identify the edge of such sheet that is the leading edge relative to said raster and;
(b) specific marking areas within said peripheral border designed for identifying a pre-determined data group for communicating information to the image communication transmission system; and
(c) marking areas designated for identifying predetermined addressee stations, and means responsive to the detection of a marking in said areas in relation to the position of scan in the raster for generating a signal indicative of one of said addressee stations.

Abstract
A header sheet for use with an automatic image communication transmission system, having regularly spaced hash marks around the border to identify the sheet as a header. Additional markings are in the border to identify the leading edge of the sheet relative to the scan raster of the system, and areas to designate sender and addressee stations by the location of markings relative to the position of the scan raster.

- 7. A document header sheet for an image communication transmission system having means for scanning successive document sheets in a predetermined scanning pattern, asymmetric means associated with said sheet, identifying said sheet as a header sheet, and means responsive to the relation of said asymmetric means to said scanning pattern for determining the orientation of said header sheet, said sheet having predetermined marking areas identifying data groups for communicating information to the image communication transmission system and predetermined marking areas designated for identifying specific addressee stations, whereby addressees are identified by the relation of the markings in said marking areas to said scanning pattern.
