An image pickup apparatus for X-ray photography is structurally adapted to absorb
external impacts and possible resultant deformations such as deflections of the
cabinet so that the interior is protected against damage and remains intact if
the cabinet is deformed by the external load. The two-dimensional image pickup
apparatus comprises a substrate, two-dimensional photoelectric converters formed
on the substrate and an apparatus cabinet containing the substrate and the photoelectric
converters. At least part of the apparatus cabinet is deformable and capable of
restoring its original profile. A plurality of containers such as air bags may
also be inserted into the gap between the substrate and the apparatus cabinet to
prevent the inner wall surface of the apparatus cabinet and the substrate from
contacting each other.
