Description

La présente invention concerne un appareil de poche pliable pour la reproduction de photographies ou d'autres documents.The present invention relates to a foldable pocket device for reproducing photographs or other documents.

Les moyens habituellement mis en oeuvre pour la reproduction rapide de documents, qu'ils soient au trait ou en demi-teintes, comportent l'emploi d'appareils coûteux, peu maniables et encombrants.The means usually employed for rapid reproduction of documents, whether in line or half - tone, involve the use of expensive equipment, unwieldy and cumbersome.

La présente invention se propose de remédier à cet inconvénient en réalisant un appareil de poche, léger, petit et peu coûteux, qui, associé à un appareil photographique, par exemple un appareil photographique du type à développement instantané, permet d'obtenir instantanément en tous lieux et à tous moments la reproduction d'un document.The present invention proposes to remedy this drawback by producing a pocket device, light, small and inexpensive, which, associated with a photographic camera, for example a photographic camera of the instant development type, makes it possible to obtain instantaneously in all places and at all times the reproduction of a document.

Dans ce but l'appareil selon l'invention est caractérisé en ce qu'il comporte un système optique, un support pour un document, un support pour monter le système optique sur l'objectif d'un appareil photographique du type à développement instantané, et un socle reliant à distance prédéterminée le support du système optique au support du dσ-cument, de manière à aligner sur l'axe optique de l'appared photographique posé sur une surface plane, ledit système optique et ledit document à reproduire.For this purpose, the apparatus according to the invention is characterized in that it comprises an optical system, a support for a document, a support for mounting the optical system on the objective of a photographic camera of the instant development type, and a base connecting at a predetermined distance the support of the optical system to the support of the dσ-cument, so as to align on the optical axis of the photographic camera placed on a flat surface, said system optical and said document to be reproduced.

La présente invention sera mieux comprise en référence à la description d'un exemple de réalisation et au dessin annexé dans lequel :

  • La figure 1 est une vue de profil et en coupe de l'appareil monté en position de travail sur un appareil photographique approprié; la figure 2 représente vu de face le support du sytème optique; la figure 3 est une vue de dessus de ce support coupé selon son axe et la figure 4 est une vue de l'appareil replié et recou- vert d'un capot.
The present invention will be better understood with reference to the description of an exemplary embodiment and to the accompanying drawing in which:
  • Figure 1 is a side view in section of the device mounted in the working position on a suitable camera; 2 shows a front view of the support of the optical system; FIG. 3 is a top view of this support cut along its axis and FIG. 4 is a view of the device folded up and covered with a cover.

En référence aux figures, le document à reproduire est placé en 1 contre un support 2 articulé par les axes 3 sur le socle 4 en forme de U. Il est retenu en haut par des pattes 5 et est pincé en bas entre le support 2 et le socle 4 qui autorisent sa mise en place lorsque le bossage 6 prévu sur le support 2 vient butter contre le bossage 7 prévu sur le socle 4 pour assurer un positionnement du support 2 perpendiculaire au socle 4. A l'autre extrémité du socle 4 est articulé un support 8 au moyen d'axes 9. Au centre de ce support se trouve un bossage circulaire dont le diamètre intérieur correspond exactement au diamètre extérieur de l'objectif 11 d'un appareil photographique 12. A l'intérieur de ce bossage 1C, et concentrique avec lui, se trouve un autre bossage 13 qui porte une lentille convergente, ou un ensemble de lentilles convergentes 14 et éventuellement un filtre coloré 15.With reference to the figures, the document to be reproduced is placed at 1 against a support 2 articulated by the axes 3 on the U-shaped base 4. It is retained at the top by lugs 5 and is pinched at the bottom between the support 2 and the base 4 which allow it to be put in place when the boss 6 provided on the support 2 comes against the boss 7 provided on the base 4 to ensure positioning of the support 2 perpendicular to the base 4. At the other end of the base 4 is articulated a support 8 by means of axes 9. In the center of this support is a circular boss, the inside diameter of which exactly corresponds to the outside diameter of the lens 11 of a camera 12. Inside this boss 1C , and concentric with it, there is another boss 13 which carries a converging lens, or a set of converging lenses 14 and possibly a color filter 15.

Si l'appareil photographique 12 comporte une cellule photo-électrique couplée, un trou 16 est pratiqué dans le support pour laisser pénétrer dans ladite cellule photo-électrique la lumière diffusée par le document 1. Si le film dont ent chargé l'appareil photographique 12 est lent, ce qui est souvent le cas pour les films en couleurs, il y a intérêt à réduire, par exemple au moyen d'un diaphragme, la lumière qui pénètre dans la cellule. Ceci permet de travailler avec un diaphragme petit et rend admissible un système optique simplifié et une construction relativement peu précise. A cet effet, une pièce 17 coulisse contre le support 8 et sous des glissières 18. Elle porte un bossage 19 qui emboîte la lunette de la cellule photo-électrique de l'appareil photographique 12 et comporte un trou 20 dont le diamètre a été déterminé pour donner la pose correcte avec le diaphragme choisi pour l'objectif 11 de l'appareil photographique. Cet-ce pièce 17 se trouve en place pour coiffer la cellule lorsqu'elle bute contre un bossage 21. Au contraire, elle découvre la totalité du trou 16 lorsqu'elle bute contre un bossage 22.If the camera 12 includes a coupled photoelectric cell, a hole 16 is made in the support to allow the light emitted by the document to penetrate into said photoelectric cell. loaded the camera 12 is slow, which is often the case for color films, it is advantageous to reduce, for example by means of a diaphragm, the light which penetrates into the cell. This makes it possible to work with a small diaphragm and makes admissible a simplified optical system and a relatively imprecise construction. For this purpose, a part 17 slides against the support 8 and under slides 18. It carries a boss 19 which fits the telescope of the photoelectric cell of the camera 12 and has a hole 20 whose diameter has been determined to give the correct exposure with the diaphragm chosen for lens 11 of the camera. This part 17 is in place to cover the cell when it abuts against a boss 21. On the contrary, it discovers the entire hole 16 when it abuts against a boss 22.

Cette pièce 17 peut en outre contenir un filtre coloré si, pour la reproduction de documents en couleurs,il est souhaitable de corriger le chromatisme de la lumière reçue par la cellule.This part 17 can also contain a color filter if, for the reproduction of color documents, it is desirable to correct the chromatism of the light received by the cell.

La hauteur du bossage 10 par rapport à la partie inférieure du socle 4 a été choisie pour que lorsque le support 8 est appliqué contre l'objectif de l'appareil photographique 12, la partie inférieure du socle 4 soit dans le même plan que la partie inférieure de l'appareil photographique 12. Il suffit donc de poser bout à bout l'appareil photographique 12 et l'appareil de reproduction, le tout étant posé sur une surface au moins approximativement plane et l'appareil de reproduction étant rendu solidaire de l'objectif 11 au moyen du bossage circulaire 10 pour obtenir un ensemble parfaitement aligné et stable. Cette stabilité obtenue par la combinaison de l'appareil de reproduction, de l'appareil photographique et d'un plan de liaison servant de suprort, autorise des temps de pose longs sans risque de bouger. Cela permet par exemple de faire travailler le système optique combiné comprenant l'objectif 11 et la lentille 14 avec un diaphragme très petit, ce qui donnera des reproductions nettes au moyen d'une solution optique sommaire et d'un ensemble socle et supports peu précis, par exemple réalisé en matière synthétique moulée.The height of the boss 10 relative to the lower part of the base 4 has been chosen so that when the support 8 is applied against the lens of the camera 12, the lower part of the base 4 is in the same plane as the part bottom of the camera 12. It is therefore sufficient to place the camera 12 and the reproduction device end to end, the whole being placed on an at least approximately flat surface and the reproduction device being made integral with the objective 11 by means of the circular boss 10 to obtain a perfectly aligned and stable assembly. This stability obtained by the combination of the reproduction apparatus, the photographic apparatus and a connection plane serving as a suprort, allows long exposure times without risk of moving. This allows for example to work the combined optical system comprising the objective 11 and the lens 14 with a very small diaphragm, which will give clear reproductions by means of a rough optical solution and a set of base and imprecise supports , for example made of molded synthetic material.

Cette stabilité permet aussi d'armer et déclencher plusieurs fois l'obturateur pour une seule exposition sans risque de bouger.This stability also makes it possible to arm and release the shutter several times for a single exposure without the risk of moving.

La puissance de la lentille 14 constituant le système optique de l'appareil a'été choisie de telle façon que lorsque l'appareil photographique 12 se trouve dans sa gamme de réglage, la mise au point correcte assure la reproduction du document 1 à l'échelle désirée, par exemple l'échelle 1/1.The power of the lens 14 constituting the system o p tick of the apparatus a'été selected such that when the camera 12 is located in its adjustable range, the correct focus ensures reproduction of the document 1 to the desired scale, for example the scale 1/1.

De préférence l'appareil photographique 12 est un appareil à développement instantané. De ce fait le document 1 est reproduit de façon extrêmement simple et quasi instantanée. Cet appareil constitue un accessoire utile pour les utilisateurs d'appareils photographiques à développement instantané du fait qu'il permet le tirage multiple d'une même prise de vue.Preferably the camera 12 is an instant developing device. Therefore document 1 is reproduced in an extremely simple and almost instantaneous manner. This camera is a useful accessory for users of instant developing cameras because it allows multiple prints of the same shot.

Lorsque l'opération de reproduction est terminée, le support 2 est basculé entre les côtés du socle 4, de même que le support 8. Ensuite un capot 25 est placé entre les côtés du socle 4, ce capot ayant comme le socle la forme d'un U, les deux U étant croisés. On constitue ainsi une petite boîte rectangulaire fermée qui se loge facilement dans une poche. L'utilisation et le fonctionnement du dispositif se font selon le processus suivant :

  • Le support 2 étant à demi-ouvert, le document 1 est glissé en haut sous les pattes 5 pour s'appuyer en bas sur le bossage 6. Le support 2 est alors amené en butée perpendiculairement au socle 4, de même que le support 8. Le dispositif ainsi déployé est ensuite monté sur l'objectif de l'appareil photographique, le tout étant posé sur une surface plane comme décrit précédemment. Il suffit alors de déclencher l'obturateur de l'appareil photographique 12 pour effectuer une prise de vue pour reproduire le document 1 de façon instantanée, à condition bien entendu que l'appareil photographique soit un appareil du type à développement instantané. La rigidité et la stabilité de l'ensemble sont obtenues par la combinaison simple de l'appareil photographique 12, de l'appareil à reproduire et d'une surface plane servant de support. L'appareil selon l'invention est peu coûteux et résoud en particulier le problème de la reproduction ou du tirage multiple de photographies prises avec un appareil photographique du type à développement instantané.
When the reproduction operation is finished, the support 2 is tilted between the sides of the base 4, as well as the support 8. Then a cover 25 is placed between the sides of the base 4, this cover having like the base the shape of 'a U, the two U being crossed. This constitutes a small closed rectangular box which fits easily in a pocket. The use and operation of the device is done according to the following process:
  • The support 2 being half-open, the document 1 is slid up under the tabs 5 to rest at the bottom on the boss 6. The support 2 is then brought into abutment perpendicular to the base 4, as is the support 8 The device thus deployed is then mounted on the objective of the camera, the whole being placed on a flat surface as described above. It then suffices to release the shutter of the camera 12 to take a picture to reproduce the document 1 instantaneously, provided of course that the camera is a device of the instant development type. The rigidity and stability of the assembly are obtained by the simple combination of the camera 12, the camera to be reproduced and a flat surface serving as a support. The apparatus according to the invention is inexpensive and solves in particular the problem of the reproduction or multiple printing of photographs taken with a photographic camera of the instant development type.
