Abstract

The system consists of marks (2) such as numerals in the corners of the transparency frame (1) which enable the user to insert the transparencies in a holder the right way up for projecting onto a screen. The corners of the frame can also be scored to allow one or more to be detached to indicate the correct position of the transparency.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un dispositif pour positionner correctement des supports de diapositives dans les bacs réservés à cet effet dans les appareils de projection dans le sens nécessaire à leur bonne projection verticalement
La projection de diapositives est traditionnellement effectuée à l'aide de projecteurs équipés de bacs où l'on dispose des supports de diapositives. The present invention relates to a device for correctly positioning slide supports in the trays reserved for this purpose in projection apparatus in the direction necessary for their proper projection vertically
Slide projection is traditionally carried out using projectors equipped with trays where slide holders are available.

La prise de vue photographique donnant lieu au développement de la diapositive pouvant être effectuée verticalement ou horizontalement, le bon positionnement du support de la diapositive dans le bac est aléatoire et de nombreuses diapositives sont mal disposées aboutissant à leurs projections dans un sens incorrect.  The photographic shooting giving rise to the development of the slide being able to be carried out vertically or horizontally, the good positioning of the support of the slide in the tray is random and many slides are badly arranged leading to their projections in an incorrect direction.

Le dispositif selon l'invention permet de remédier à cet inconvénient.  The device according to the invention overcomes this drawback.

Il comporte selon une première caractéristique un support de diapositive muni de quatre repéres à chacun de ses angles.  According to a first characteristic, it has a slide support provided with four marks at each of its angles.

Il comporte selon une seconde caractéristique quatre pré-découpes à chaque angle du support de diapositive.  According to a second characteristic, it comprises four pre-cuts at each angle of the slide support.

Chaque repére peut représenter n'importe quel signe distictif comme par exemple un numéro afin de classer les diapositives.  Each marker can represent any distictive sign such as a number in order to classify the slides.

Ce repére peut être positionné d'une façon différente à chaque angle afin qu'une fois le repérage effectué, ce signe distinctif soit positionné d'une façon reconnaissable par l'utilisateur.  This marking can be positioned in a different way at each angle so that once the marking has been carried out, this distinctive sign is positioned in a manner recognizable by the user.

Il suffit à l'utilisateur de positionner le support de diapositive dans le sens adéquat à la projection dans le sens désiré, enlever l'angle du support grace à la pré-découpe dans le bon positionnement souhaité et le support de diapositive sera toujours positionné dans le sens souhaité.  The user just has to position the slide support in the correct direction for the projection in the desired direction, remove the angle of the support thanks to the pre-cut in the correct desired position and the slide support will always be positioned in the desired meaning.

Le dessin annexé illustre l'invention : La figure 1 représente l'invention vue de face.  The accompanying drawing illustrates the invention: Figure 1 shows the invention seen from the front.

En référence à ce dessin, le dispositif comporte un support de diapositive 1 muni de repéres 2 à chacun de ses angles et de pré-découpes 3 à chacun de ses angles. With reference to this drawing, the device comprises a slide support 1 provided with marks 2 at each of its angles and pre-cuts 3 at each of its angles.

La présente invention n'est pas limitée aux modes de réalisation décrits à titre d'exemples non limitatifs mais s'étend au contraire à toutes les variantes envisageables.  The present invention is not limited to the embodiments described by way of nonlimiting examples but, on the contrary, extends to all possible variants.

Le dispositif selon l'invention est particuliérement destiné au positionnement pour leur projection des supports de diapositives. The device according to the invention is particularly intended for positioning their projection of slide supports.
