IMAGING DEVICE FOR UNIFORMLY HOLDING AN INTERVAL BETWEEN A PHOTOSENSITIVE FILM AND A ROD-LENS

摘要

PURPOSE: An imaging device is provided to correct the bend of a photosensitive film although the bend is generated in the photosensitive film and uniformly hold an interval between the photosensitive film and a rod-lens. CONSTITUTION: A protrusion(23a) is formed in a print head(2) of an imaging device. The protrusion is offset to a lens(22a) in a sub-scan direction, and is protruded near a photosensitive recording medium(4). The protrusion is adjacent to the photosensitive recording medium. The protrusion is moved in a state in which the protrusion is contacted with the photosensitive recording medium in exposure, and the bend of the photosensitive recording medium is corrected.
