• the rectangular frame 92 of the motorized frame support 90 does not include background and is therefore through to allow the backlighting of the components to be inspected.
• the coupling / drive between the coupling end piece 96 of the shaft of the motor 95 as well as the end piece 47a of the rotating part 44a of the laying frame 10 is made, according to the embodiment of the figure 32, by magnetic coupling thanks to two magnetic end pieces.
• other coupling/drive systems for example a drive by profiled end pieces or by a toothed belt which would be directly slaved to the toothed ring 46.
• the frame 92 of the motorized frame support is not necessarily rectangular and can be adapted according to the shape of the rigid cage 10a.
• the frame 92 may also have only three supports, this number of supports being sufficient to guarantee the stability of the rigid cage when it is mounted in the frame of the motorized frame support.
• Adjuster 31 First and second V-shaped supports 28a, 28b First and second sliding alignment stops 30a, 30b
• Control device Lighting system 60 Camera 62
