Abstract

The invention provides a linear barcode scanner which comprises a light source assembly and further comprises a shell which comprises a receiving end with a code scanning opening and a connecting end arranged far away from the receiving end. a lens assembly is fixed in the shell and is arranged corresponding to the code scanning port; at least part of the PCB is contained in the shell, and the PCB is located at the connecting end; an image sensor is fixed on the PCB (Printed Circuit Board) and is electrically connected with the PCB; a positioning device is fixed on the PCB so as to limit the relative position of the PCB connected with the image sensor and the lens assembly. According to the invention, the image sensor is fixed on the PCB in a surface mounting manner, so that a ceramic outer frame is prevented from being used for packaging, and the problem that the ultra-thin requirement of an existing bar code scanner product is difficult to meet due to a ceramic outer frame packaging process of the image sensor is solved.

Description

technical field [0001] The invention relates to a linear barcode scanner and belongs to the technical field of optical scanners. Background technique [0002] A barcode scanner is an electronic device used to read or scan barcodes and / or information contained on items. It uses optical principles to decode the content of barcodes into digital signals acceptable to computers. It is widely used in supermarkets, logistics express, books, etc. The field of barcode scanning for scanning commodities and documents such as museums. [0003] In traditional linear barcode scanners, image sensor elements with ceramic frame package protection are generally used to protect the material of the image sensor and position the relative position of the image sensor in the package, and control its offset tolerance within 10um . However, with the requirement for miniaturization and ultra-thinness of barcode scanner products, the size requirements for ceramic frame packages are also increasingly...
