Handheld barcode scanner

Abstract

The invention relates to a handheld barcode scanner which mainly comprises a main machine body, a handle connected with the main machine body, and a key pivoted on the handle, wherein a magnetic sensing element and a magnet are respectively installed inside the main machine body and the handle. When a user does not press the key, the magnetic sensing element does not sense the magnetic force of the magnet and thus does not trigger a drive circuit board of the main machine body; and when the user presses the key, the magnetic sensing element senses the magnetic force of the magnet and triggers the drive circuit board of the main machine body to enable the drive circuit board to drive a scanning unit to perform scanning operation.

Description

technical field [0001] The present invention relates to a hand-held barcode scanner, in particular to a hand-held barcode scanner. Background technique [0002] At present, there are barcodes printed on the product packaging on the market. After scanning by the barcode scanner and processing with the identification system, the product information such as the product name, item number and price represented by the barcode can be read out, and then Achieve fast, convenient and correct automated commodity management. [0003] In order to increase the convenience of use, some barcode scanners will be equipped with grip 2, such as figure 1 As shown, the button 3 is set on the handle 2. When the user holds the handle 2 with one hand, he only needs to press the button 3 with his finger to scan the barcode of the product. [0004] However, in the traditional design, a perforation must be opened between the main body 1 and the handle 2 to allow the wire 5 to pass through, so that th...

[0004] However, in the traditional design, a perforation must be opened between the main body 1 and the handle 2 to allow the wire 5 to pass through, so that the user can trigger the drive circuit board 4 of the main body 1 through the button 3 of the handle 2. However, the existence of the perforation will definitely affect the waterproofness of the overall structure. Therefore, the well-known handheld barcode scanner will add a plug 6 between the two perforations of the main body 1 and the handle 2 to seal it. However, the plug The setting of part 6 will not only increase the difficulty of assembly, but the waterproof effect provided by plug part 6 is still quite limited, and when the barcode scanner is not equipped with handle 2, the perforation will also affect the appearance
