Bar code sanner

Abstract

A bar code scanner comprises a housing and an optical module. A fixing station is arranged at one side of an interior of the housing and is used for fixing the optical module; one side opposite to the side where the fixing station is arranged is an inclined surface, and the inclined surface is inclined facing a bottom surface and is provided with a reflection plate; and the bottom surface is provided with a view port, which is used for making optical beams emitted by the optical module shining on a bar code. According to the bar code scanner, the optical module is fixed on the interior of the housing by means of mating between the fixing station and the housing, and a new optical path is formed by means of inclination arrangement of the inclined surface and the bottom surface, so as to effectively shorten a scanning distance in a relatively small volume, and maintain validity and accuracy of reading data by the optical beams, and therefore, zero-distance code-scanning is implemented, that is, a desired bar code can be scanned with the only need for attaching the view port on the bar code.

Description

technical field [0001] The invention relates to the technical field of electronic scanning equipment, in particular to a barcode scanner. Background technique [0002] Barcode scanner, also known as barcode reader, barcode scanning gun, barcode scanner, barcode scanning gun and barcode reader, is a reading device used to read the information contained in the barcode, using optical principles to decode the content of the barcode After that, it is transmitted to a computer or other equipment through a data line or wirelessly, and is widely used in supermarkets, logistics express, libraries, etc. to scan the barcodes of commodities and documents. [0003] In the current barcode scanner, the scanning method usually requires a certain distance and a certain angle to scan the barcode, but this method often has the following situations: 1. The barcode can only be read within a specified distance; 2. , The angle must be within the specified range to read the barcode; 3, It is easy ...

Problems solved by technology

[0003] In the current barcode scanner, the scanning method usually requires a certain distance and a certain angle to scan the barcode, but this method often has the following situations: 1. The barcode can only be read within a specified distance; 2. , The angle must be within the specified range to read the barcode; 3. It is easy to shake when reading the barcode

The above situations will directly affect the scanning results, and there are often wrong and missing scans, which is very inconvenient to use and has a high error rate in scanning results.
