BARCODE READER USED A MIXED MIRROR

摘要

PURPOSE: A barcode reader using a mixed mirror are provided to realize miniaturization and save manufacturing cost by realizing the barcode reader with the mixed mirror which a flat mirror and curved mirror are applied into one body. CONSTITUTION: A light source(110) outputs light. A mixed mirror comprises a flat mirror(121) of a flat type in a part of one side and a curved mirror(122) of a curved shape in the remaining part. The flat mirror reflects an outputted light by the light source and makes incident to a bar code(200). The curved mirror reflects the light reflected from the bar code. An optical detector detects the light reflected by the curved mirror.
