Patent ID: 8035869

Claim:
An image reading device comprising: a transparent member shaped like a flat plate and having an image reading area; a line sensor that moves along the transparent member in a line sensor moving direction, which is perpendicular to a reading line direction of the line sensor, so as to read an image of a document placed on the image reading area; a first supporting structure that supports, at opposite ends of the image reading area with respect to the line sensor moving direction, the transparent member rigidly with respect to the reading line direction, such that the transparent member is not deformed with respect to the reading line direction when an external force is applied to the transparent member; and a second supporting structure that supports, at opposite ends of the image reading area with respect to the reading line direction, the transparent member with respect to the line sensor moving direction, such that the transparent member is movable between a first posture, where the transparent member is in the flat plate shape, and a second posture, where the transparent member is bent with respect to the line sensor moving direction.
