LIGHT PIPE FOR ACCURATE ERASURE OF PHOTOCONDUCTOR CHARGE |
摘要 |
<p>LIGHT PIPE FOR ACCURATE ERASURE OF PHOTOCONDUCTOR CHARGE Erase apparatus for use in an electrophotographic copier machine where an array of light-emitting diodes (LEDs) are placed adjacent one end of a light channel with the other end adjacent a moving photoreceptive surface. The channel allows light rays to pass freely from LED to LED but contains the rays in a direction parallel to the direction of photoreceptor movement. The channel may be comprised of sides with reflective surfaces normal to the photoreceptive surface or may be a solid plastic sheet through which the rays pass. In the latter embodiment, rays are internally reflected from the surfaces of the plastic sheet. BO978013</p> |
