| 1. A sheet conveyor comprising:
a conveyor belt that conveys a sheet material while holding the sheet material by attraction with an electric force; and
a platen slidably supporting a bottom surface of the conveyor belt so as to maintain flatness of a predetermined region of
the conveyor belt,
wherein the upstream side of the platen is inclined at a non-zero predetermined angle with respect to a direction perpendicular
to a conveying direction of the conveyor belt such that a surface of the platen that is in contact with the conveyor belt
has a width that increases gradually from an upstream side of the platen towards a downstream side thereof in a conveying
direction of the conveyor belt.
