Image reader and image recorder with interposed photochromic material for reducing flare |
| abstract |
An optical scanning image reader and an optical scanning image recorder are disclosed. The image reader is provided with a light source for emitting an optical beam that scans a recording material on which an image is recorded, a photodetector for reading an image by photoelectrically detecting light that has a wavelength differing from that of the optical beam and is emitted from the recording material as a result of the scanning of the recording material, and a photochromic material which increases transmissivity upon exposure to the optical beam but decreasing the transmissivity upon exposure to the emitted light. The photochromic material is positioned in proximity to, or in close contact with, the recording material, and the photodetector is positioned so as to receive the emitted light through the photochromic material. The photochromic material may have a nonlinear characteristic that increases transmissivity upon exposure to the reading optical beam but decreases a property of changing transmissivity in accordance with an optical intensity to a considerably low degree in a low optical intensity region, and the photochromic material is positioned so as to receive the reading optical beam advancing towards the recording material. Flare light advancing towards areas other than a predetermined scanning point on the recording material cannot pass through the photochromic material, and hence the influence of the flare light can be prevented. |
