Title (EN) A COMPACT CONTACT PRINTER WITH A FLEXIBLE TRANSPARENT COVER SHEET
(FR) COPIEUR PAR CONTACT COMPACT EQUIPE D'UNE FEUILLE DE COUVERTURE SOUPLE ET TRANSPARENTE
Abstract:
(EN) An improvement in a contact printer (10) which comprises means for supporting a film and an original in superposed relationship on a vacuum table, means for providing a source (32) of light for exposing the film through the original, and means for moving the light over the surface of the superposed film and original. The improvement comprises means carried by the light moving means for covering the superposed film (18) and original (20) with a substantially impervious flexible and transparent cover sheet (36) as the exposing light is scanned across the film and original whereby the vacuum is applied to the film, and the original to remove air from therebetween as the film is exposed by the light through the cover sheet and the original.
(FR) Amélioration d'un copieur par contact (10) qui comprend un système destiné à soutenir une feuille et un original de manière superposée sur une table à vide, un système pour fournir une source (32) de lumière pour exposer la feuille à travers l'original, et un système pour déplacer la lumière au-dessus de la surface de la superpositon de la feuille et de l'orginal. L'amélioration comprend un dispositif porté par le système de déplacement de la lumière pour recouvrir la feuille superposée (18) et l'orginal (20) d'une feuille de protection transparente, souple et imperméable (36) lorsque la lumière d'exposition est balayée sur la feuille et l'original, ce qui applique le vide sur la feuille et l'orignal pour enlever l'air qui se trouve entre les deux lorsque la feuille est exposée à la lumière à travers la feuille de couverture et l'original.
