Method and apparatus for reading and writing indicia such as bar codes using a scanned laser |
摘要 |
A system for reading and writing indicia on a medium including a light source for producing a light beam; a reading element for directing the light beam at the medium so as to scan indicia disposed on a first portion of said medium, detecting at least a portion of the light of variable intensity reflected off the indicia, and generating an electrical signal indicative of the detected light intensity; and a writing element for directing the light beam at the medium in a pattern on a second portion of the medium so as record information on the medium. The light beam is preferably a laser beam generated by a semiconductor laser, and a mirror is used to scan the beam both for reading and writing.
