a document bed on which a document is placed;
an opening/closing member configured to be opened/closed with respect to the document bed;
a rotational supporting section provided at one end of the document bed and configured to support the opening/closing member to rotate with respect to the document bed; and
a height adjustment mechanism that adjusts a height of the opening/closing member relative to the document bed, wherein
the rotational supporting section includes
a holding section fixed to the document bed, and
a rotary fulcrum section attached to the holding section and configured to be moved in an up-down direction relative to the holding section,
the height adjustment mechanism
includes a rotator rotating about a rotating axis with respect to the holding section,
adjusts a height of the rotary fulcrum section relative to the holding section to adjust the height of the opening/closing member relative to the document bed based on a rotation of the rotator about the rotating axis, and
overlaps the holding section and the rotary fulcrum section in a vertical direction, and
the holding section and the rotating axis of the rotator are not moved with respect to the document bed while the rotary fulcrum is moved in the up-down direction.
