ABSTRACT:
An improved image input apparatus 1 prevents foreign particles from attaching onto image reading areas of transparency media contained within the apparatus by providing feeding block structure 13 that substantially covers an area between a loading cartridge 11 and a take-up housing 15, except for a small slit-shaped window 13a formed in block 13 in a direction intersecting a direction of movement of the media through the block. The window 13a preferably has a sloping part 13d inclined toward a light axis L1 of an illumination system 12 that passes through the transparency media. The feeding block 13 may also be provided with a pressing member 13b that acts with rails 13c to press on the transparency media and prevent curling.
