Definitions

  • the present invention concerns a holding and layout device intended for use in process cameras, especially for large colour pictures and maps, which consists of surfaces in frames to be placed against one another, of which one is a glass sheet for showing the picture to the lens, and which includes a frame member round which the frames are free to turn round a common centre of gravity from a vertical to a horizontal position, which correspond to the photographing and layout position.
  • the most common holder that operates in a vertical position is the so-called lift foil holder.
  • the original picture is placed on the baseboard first of all slightly under the foil roll, which is attached by an axle to the lift device.
  • the foil roll in the lift is then drawn over the picture so that the original picture is covered by the foil coming from the roll.
  • the foil is pressed against the original picture by sucking out the air between the foil and the base ⁇ board by means of a system built into the apparatus.

Abstract

Support et dispositif de présentation pour originaux destinés aux appareils photographiques de reproduction, surtout pour grandes images et cartes en couleur. Le dispositif comporte deux surfaces (1, 2) montées dans des cadres (3, 4), l'une des surfaces étant une plaque de verre (2) permettant de disposer l'image devant l'objectif, les cadres étant équipés de charnières (5) sur l'un des côtés afin de permettre leur rotation l'un par rapport à l'autre. Le dispositif comporte une partie à cadre autour de laquelle les cadres (3, 4) peuvent tourner essentiellement autour de leur centre de gravité depuis une position verticale jusqu'à une position horizontale. L'invention a pour objet de permettre la réalisation d'un support original simple mais fiable et d'un emploi facile, qui dans la position horizontale peut également servir de véritable table de présentation. Dans le support décrit, la surface orientable inférieure constitue la plaque de verre (2) mentionnée ci-dessus qui est orientée vers l'objectif. Dans ce cas elle constitue, dans la position horizontale, une table d'éclairage à l'aide des lampes auxiliaires (10). La deuxième caractéristique importante de l'invention est constituée par le fait que l'autre surface (1) est une membrane mate hautement translucide, par exemple en feuilles de polyester à laquelle on a appliqué par voie chimique une surface mate. La diffusion du rétro-éclairage au moyen de la membrane mate permet de supprimer, sur la copie, la plupart des rayures présentes dans l'original.
