Abstract

1436631 Colour electro-photography HITACHI Ltd 9 April 1973 [12 April 1972(2)] 16844/73 Heading G2H A photo-conductive copy material 4 is fed from roll 10 in web form, and each length in turn is fixed in a stationary position, by a pin through a portion which is later cut off, while it receives repeated chargings, colour-separation exposures and liquid developments from travelling apparatus, then is cut to size and delivered. Development is carried out by a horizontally and vertically movable apparatus, which applies liquid developer to the material 4 as it moves horizontally, then is raised to apply liquid developer of a different colour after a further exposure. Preferably four separate exposures and developments are made, corresponding to three colour images and one black image. Reference has been directed by the Comptroller to Specification 1316651.
