Abstract:
A stylus for use in an electric discharge facsimile recorder having a mounting means adapted for connection to an endless belt. The mounting which holds the stylus also includes means for accurately adjusting its relative position with respect to the recording paper. The stylus is constructed from a metal alloy and includes a fine point for improved resolution and long life.
Abstract:
A magnetic holding drum particularly suitable for optical reproduction devices such as facsimile transmitters, which enables the copy to be held substantially flat over the surface of the drum while the drum is either rotated or optically scanned. The drum includes a plurality of spaced-apart, radially disposed elongated magnets on its cylindrical surface. A sliding holder which is slidably retained in grooves at each end of the drum is magnetically affixed at any desired position on the surface of the drum in order to maintain the copy flattened against the drum''s surface.
Abstract:
A simplified and effective optical system for facsimile scanners and the like wherein a plurality of prefocussed lamps illuminate the scanning spot and a coaxial lens system directs the reflected light through an aperture disposed in front of a photo-electric device for producing an electrical signal in response to changes in contrast of the scanning spot.
