Abstract

According to the bar code reading module provided by the invention, under the condition of meeting the functions of illumination and aiming, a circuit design board which causes the largest size of the bar code module in the prior art is split into three circuit boards, so that the height of the bar code reading module can be close to the height of the split circuit board; by integrating devices for executing illumination, aiming and camera shooting on the first circuit board and setting signal control on the second circuit board, the instruction sending efficiency is improved, and only one group of signals are needed for transmission. The lens camera module is detachably mounted on the first circuit board, so that the lens camera module is convenient to upgrade subsequently.

Description

technical field [0001] The invention relates to a barcode reading device, in particular to a barcode reading module. Background technique [0002] As the core component of barcode reading, the barcode reading module has complete functions of barcode image acquisition, image processing, barcode image decoding and decoding result output, and is the core component of various barcode terminal products. As the size of mobile phones, tablets, and handheld smart terminals (PDAs) becomes smaller and thinner, the traditional barcode reading modules are thicker in size, especially thicker in height. The poor size compatibility has led to the fact that many barcode collection, decoding, and output tasks originally completed by the barcode reading module are completed by the built-in cameras of mobile phones and tablets. [0003] With the improvement of the performance of processors such as mobile phones and tablets, and the development of the Internet, some barcode decoding algorithms...
