Abstract

The invention relates to a device making it possible to magnify an image (1) displayed on the screen (2) of an apparatus (3) so as to make it easier to see it. It consists of a plate (4) provided with an anti-glare magnifying glass (5). The plate (4) rests on the apparatus (3) by means of two pads (7) which can move about the axis (6). When the user tightens the two screws (8), the plate (4), which includes two lateral perforations (9) allowing circulation of air, covers the screen (2) of the apparatus (3) and the displayed image (1) is magnified by the anti-glare magnifying glass (5). The device according to the invention is particularly intended for use with portable microcomputers.

Description

La présente invention concerne un dispositif permettant de grossir une image affichée sur l'écran d'un appareil. The present invention relates to a device for magnifying an image displayed on the screen of a device.

La miniaturisation et l'utilisation prolongée de certains appareils munis d'écrans de format réduit, provoque chez l'utilisateur, d'une part, une fatigue oculaire, et d'autre part, une fatigue musculaire due en grande partie à la position de son corps. The miniaturization and the prolonged use of certain devices provided with screens of reduced size, causes on the user, on the one hand, eye fatigue, and on the other hand, muscle fatigue due in large part to the position of his body.

Le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte en effet selon une première caractéristique une plaque pourvue d'une loupe anti-reflets. Après que l'utilisateur ait posé et fixé la plaque sur l'appareil, le grossissement de l'image permet d'en augmenter le rayon visuel. The device according to the invention overcomes this drawback. According to a first characteristic, it comprises a plate provided with an anti-reflection magnifier. After the user has placed and fixed the plate on the device, the magnification of the image increases its visual radius.

Les dessins annexés illustrent l'invention
La figure 1 représente l'image normale affichée sur l'écran de l'appareil.The accompanying drawings illustrate the invention
Figure 1 shows the normal image displayed on the device screen.

La figure 2 représente l'image affichée selon le dispositif de l'invention.FIG. 2 represents the image displayed according to the device of the invention.

En référence à la figure 2, le dispositif comporte une plaque (4) la loupe anti-reflets (5) en est une partie. L'axe (6) relie la plaque (4) aux deux pattes (7) munies d'une vis de blocage (8). Les pattes (7) sont mobiles autour de l'axe (6). Les deux perforations (9) latérales sur la plaque (4) permettent la circulation de l'air. Referring to Figure 2, the device comprises a plate (4) the anti-reflection lens (5) is a part of it. The axis (6) connects the plate (4) to the two legs (7) provided with a locking screw (8). The legs (7) are movable around the axis (6). The two lateral perforations (9) on the plate (4) allow air circulation.

A titre d'exemple non limitatif, le dispositif aura des dimensions de l'ordre de 20 à 25 cm pour la longueur et de 15 à 20 cm pour la largeur. By way of nonlimiting example, the device will have dimensions of the order of 20 to 25 cm for the length and 15 to 20 cm for the width.

Le dispositif selon l'invention est notamment destiné à l'utilisation des micro-ordinateurs portables.  The device according to the invention is in particular intended for the use of portable microcomputers.
