Description:
The 120° book holder
option allows the digitisation of books which cannot
be flat open at 180°, without any risk of deterioration.
The open angle being clearly inferior to 180°, it
is not possible to scan simultaneously both right and
left pages in good conditions.
The 120° book
holder option maintains the volume with the appropriate
open angle and allows the flat setting of the page to
digitise (right or left) in parallel to the lighting.

The 120° mechanics
of the book holder is conceived to respect the book
which is implicitly fragile and requires great handling
cares.
Positioning plans of the book are realized
in materials preserving the book covers and their back.
Everything is foreseen to avoid contacts on hard salient
areas.
The 120° option is
dedicated to bound 2 x A3 format volumes, of a maximum
thickness of 150mm, with possible apertures to 100,
120 and 140°.
It can adapt on book cradles 30
and 50cm thickness, and with certain restrictions on
the book cradle 12cm. The 120° option uses the one-direction
scanning mode from the left to the right hand-side.
To note that the 120°
option can be equipped with a glass plate which allows
to flatten the pages of the book to digitise. As per
the glass option, a security system forbids any digitisation
when the glass is lifted.

Operating mode:
The 120° option is
positioned on the plates of a book cradle. The document
is open. The page to digitise (right or left) is flatly
set. The left hand-side of the apparatus is adjusted
so that an optimal book angle aperture is obtained.
The resolution is set thanks to height setting of the
book cradle plates, to the mechanical adjustment kit
of the camera, to the setting of the telemeter of the
focus of the camera and to the setting function of the
DigiBook software.
The use of the 120°
book holder only allows the digitisation of the right
page. To minimize the volume handlings, one will have
to digitise all the pages from one side and invert the
volume position on the book holder. Thus, the left pages
being scanned, the DigiBook software functions will
allow the 180° rotation of the images and the insertion
of the right pages.
