Embodiment Construction
[0031] figure 2 and image 3 A scanner according to the invention is shown schematically.
[0032] Scanners conventionally comprise rollers 7 driving the document 2 to be scanned, including the front and back sides. The roller 7 is mounted to rotate about an axis.
[0033] Expect to scan the front and back of document 2.
[0034] The scanner thus comprises a module 10 located on the front side of the document 2 and a module 11 located on the reverse side of the document 2 .
[0035] The modules 10 and 11 can be separate elements or integrated, and the modules 10 and 11 are of course arranged to enable the passage of the document 2 in the passage direction X.
[0036] In order to reduce the distance I between the axes of rotation of the rollers 7, each module 10 or 11 is placed substantially facing each other, that is to say with an overlapping area Δ with respect to the direction X, as figure 2 shown.
[0037] Preferably, each of the modules 10 and 11 is centered with ...
