The transport belt [A] and the two support arms [B] are formed as one unit,
(made of aluminum). This results in a more flexible structure than the
monocoque type (in which the cover carries all of the stress), and the gap
between the transport belt and the original can easily be kept precise during
belt transport.
On the support arm linked with the DJF hinge [C], there is a fulcrum [D] to
support the DJF. When the DJF is being closed and the rear stopper [E]
contacts the base copier first, the DJF rotates about the fulcrum, rotates and
the front stopper [F] will also contact the base copier to level the belt with the
exposure glass.
