Definitions

• the boxes presented in this document do not allow either manipulation of the object to be examined and the simultaneous implementation of a sufficiently uniform illumination of this object to allow the remote presentation of this object under good viewing conditions for an interlocutor located at a distance (FIGS. 3 to 5), ie simultaneous manipulation and shooting of the object to be examined (FIGS. 6 and 7).
• the light sources not arranged in a sufficiently regular manner around the housing, but also several dark areas are unavoidable and could be detected on the shots, depending on the nature of the object to be examined, in particular if the latter comprises at least one reflective surface as is for example the case of a watch with its glass and sometimes its case.
• the bottom and the access door(s) to the housing constitute such dark areas, so any faces of the object to be examined oriented towards the bottom or the top of the box will not be as well illuminated as its sides. side faces.
• the cover has a generally curved shape with no sharp edge.
• the display screen may be the screen of a tablet secured to the protective shell by means of a suitable support.
• the suitable support can also be made for the suitable support to be arranged so as to allow the tablet to pivot with reference to the protective shell, between an active position, deployed, and an inactive position, folded towards the protective shell.
• FIG. 2 shows a simplified side view of part of the illumination box of Figure 1;
• FIG. 3 shows a simplified perspective view of the illumination box of Figure 1 on which part of the box is removed to reveal certain construction details;
• the whole of the envelope here behaves like a light guide, over its entire extent, that is to say both at the level of the cover 4, the bottom 2 and the interface between these two elements, giving rise to a continuous and uniform illumination of much better quality than with the devices of the prior art.
• This dome shape allows in particular the production of a more compact illumination box than that illustrated in Figures 1 to 3.
• the nature of this particular application has a direct impact on the dimensions of the box 1, 100 and, more particularly, the distance between the two openings 12 (when there are two).
• the distance between the two openings 12 should preferably be between approximately 30 and 60 cm to guarantee a comfortable posture for the operator during use. Consequently, even if it is possible to produce a box 1 of greater length without thereby departing from the scope of the invention as defined by the claims, there is little point in its length exceeding 80cm . It appears from the views of Figures 7, 8 and 9 that, in the service position, the lens of the camera or the camera used (therefore that of the camera 14 or the hole 16) is located substantially between the eyes of the operator and the housing 10.
