A line CCD scanner includes a photo film passageway in which developed photo
film
is positioned. A light source illuminates an image in the photo film positioned
in the photo film passageway. A line CCD reads the image being illuminated. A mask
member is secured to the photo film passageway. The image is positioned at the
mask member. A mask slit is formed in the mask member, for directing light from
the light source toward the photo film. The mask slit has a small width with reference
to a predetermined direction. Furthermore, a protrusion portion is disposed on
the mask member to extend in the width direction of the photo film, provided with
the mask slit formed in a middle thereof, for flexing the photo film in the longitudinal
direction to remove flexing in the width direction.
