An improved platen cover for a copying machine |
摘要 |
An improved platen cover for overlying original documents disposed atop a transparent plate for optical scanning in a copying machine includes marks or patterns on its surface facing the transparent plate. The marks or patterns are placed on the platen cover surface utilizing a fluorescent paint so that the marks or patterns do not reproduce on or degrade the quality of the copy of the original document operatively produced by the machine.
