Description:
For all users of book
cradle (models: Book Cradle12.15, 30 or 50), the glass
option becomes essential in the following situations:
to digitise
small, thick books, which usually lay out of very
stiff binding and that have a tendency to close
naturally or to present pages like a hand-held fan,
to digitise
inserts - documents inserted on a page - which have
to be unfolded and set flat,
to minimize
the operator's physical contact.
From a conservation point
of view, the glass plate option allows the demeanour
of pages with no direct operator's contact.
The glass plate option
covers an A2 landscape format (2 x A3) i.e. 420 mm (H)
x 594 mm (L). The glass option is compatible with the
bi-directionnal scanning mode.
The glass option adapts
itself on all the scanners of the SUPRASCAN range, and
on the DigiBook 2000LC model. In the A0 scanner case
(DigiBook A0), a specific kit of assembly is necessary
to fix the option directly on the book cradle 12, 15,
30 or 50 cm thickness (GLASS-KITA0).
Operation mode:
The scanner arm in position
0, left or right hand side (see image 1), the whole
of the glass option apparatus can be accessed by the
operator who can manoeuvre the glass plate (in an open
or closed position) thanks to a knob disposed on the
front side. The 60° aperture position of the glass
plate allows the positioning of the book on the plates
of the book cradle or the page-turning of the book.
The operator lowers the glass in a horizontal position
(see image 2) to flatten the pages to scan, Consequently,
the scanning process can start.

The pros of the glass
option:
No crash of the book:
the glass swivels
around an adjustable hinge (approx. + or - 30 mm
of vertical race) which takes into account the height
variations of the volume and avoids the crash of
the top of the book when the operator lowers the
glass. The only weight of the glass plate allows
to flatten the pages of the book.
No reflection induced
by the lighting source:
when the glass is
set on the book, it remains in a perfectly horizontal
position.
Demeanour of the glass
in a lifted position with no assistance:
The operator is free
in his movements, for an optimal handling, between
the digitisations.
Automatic open-glass
detection:
as soon as the glass
is lifted of some degrees, an integrated detector
in the hinge gives a stop signal to the scanner
in order to forbid or immediately stop the scanning.
A high-qality glass:
the material constituting
the glass plate has been rigorously selected to
guarantee a perfect digitisation: optimal transparency
for a maximum lighting transmission, colour conservation
(no tint, no colour filter) and minimum image distorsion
thanks to a very homogeneous glass.
