1335980 Facsimile apparatus XEROX CORP 21 Dec 1970 [23 Dec 1969] 60520/70 Heading H4F Relates to a facsimile colour printer employing a light-sensitive transform computer as described in Specification 1,335,222, in which two beam splitters are used to split the light from the scanned original into three beams which are photo-electrically detected via red, green and blue filters. The beam splitters may be colour selective. By using a mandrel having a different diameter portion for the original than for the three colour ink printing plates, copies of different sizes may be produced.
