Bar code reading device

Abstract

The invention discloses a bar code reading device. The bar code reading device includes a shell and a PCB (printed circuit board) structure; the printed circuit board structure is arranged in the shell; and the printed circuit board structure includes a main board, an auxiliary board, a connecting bracket and a communication line, wherein the main board is fixedly connected with the auxiliary board through the connecting bracket, and the communication line is used for enabling communication between the main board and the auxiliary board. With the bar code reading device adopted, under the situation that the size of the printed circuit board structure is not increased, the problems of light loss, aberration increase and influence on imaging quality caused by adopting a reflecting mirror in the prior art can be solved, and the problems of low decoding inefficiency and poor user experience caused by weak prompting voice and a requirement for a large gripping triggering force, which are caused by serious deviation of light from a decoding plane when a reflecting mirror is not adopted, can be solved.

Description

technical field [0001] The invention relates to a reading device, in particular to a barcode reading device. Background technique [0002] As a high-tech product closely integrating optical, mechanical, electronic, software application and other technologies, barcode reading equipment is the third generation of main computer input equipment after keyboard and mouse. Since the birth of scanning guns in the 1980s, they have developed rapidly and been widely used. From the most direct pictures, photos, films to various drawings, graphics and manuscript materials, they can be input into the computer with scanning guns, and then these images can be scanned. The processing, management, use, storage or output of information. [0003] In barcode reading equipment, PCB circuit board (printed circuit board) is used as the carrier of electronic components and provides electrical connection; through layout design, it can greatly reduce wiring and assembly errors, saving equipment maint...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a barcode reading device with a compact structure, which can solve the problem of light energy loss caused by the use of reflectors in the prior art, increasing aberrations and affecting The problem of image quality can also solve the problem of not using a reflector so that the light seriously deviates from the decoding plane, resulting in low decoding efficiency, weak prompt sound and strong trigger force required by the hand, and poor user experience.
