Patent number: 4029404Abstract: In a vacuum contact printer there are provided a winding roller to which one end of a resilient vacuum sheet is attached and a pressure roller for pressing the sheet against a glass plate. Along with the advancement of both rollers, which are rotatably supported on a pair of bearing plates movable in a longitudinal direction, the sheet automatically spreads over the glass plate, being wound off the winding roller and simultaneously being pressed by the pressure roller so that all the air kept between the sheet and the glass plate is completely expelled. In addition, a suctorial operation encourages a closer adhesion of the sheet to the glass plate, whereby a document and a sensitive material placed between them can be sufficiently in close contact with each other.Type: GrantFiled: November 7, 1975Date of Patent: June 14, 1977Assignee: Dainippon Screen Seizo Kabushiki-KaishaInventors: Hidekatsu Mizukami, Kosuke Fukui, Tsutomu Kinoshita
