Claims

[Claims for Utility Model Registration] A lens held in a case, a light-emitting element that emits light to the barcode through the lens, and a light-receiving element that receives reflected light from the barcode through the lens. In an optical device for reading barcodes, both of the elements have an insulating molded body integrated with a metal frame as a substrate, are mounted on the metal frame electrically isolated from each other, and are attached by wire bonding. An optical device for reading barcodes.
