Description

technical field [0001] The invention relates to the field of barcode identification, in particular to a barcode reading and decoding module and a handheld electronic device. Background technique [0002] Barcode scanner is an input device that converts barcode information into computer-acceptable information by using the principle of photoelectricity. It is often used in libraries, hospitals, bookstores and supermarkets as an input method for quick registration or settlement. The image or barcode information on the printed matter is directly read and input into the online system. Therefore, the barcode scanner must at least have the functions of reading and decoding, and most of the existing technologies use a barcode reading module (imaging module, imaging head) with a decoding circuit board to realize the aforementioned functions. [0003] The electronic circuit architecture of the existing barcode reading module mainly uses a microprocessor (CPU) with a random access mem...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the overall structure of the existing barcode reading module needs to be equipped with circuit boards of image sensor chips, optical lenses, lighting circuit boards and other components in order to fix them and prevent external non-imaging light from affecting image transmission. Sensor chip image quality

Due to the need to carry more components, even including the fixing of various circuit boards, the structural size of the entire barcode reading module is difficult to achieve 1000mm 3 Therefore, it has defects such as large size, high power consumption, many components, and high cost, which is not conducive to the miniaturization design of the barcode reading module

If it is necessary to further incorporate the decoding function into the decoding and reading module to form a barcode reading and decoding module, it is even more difficult to achieve a miniaturized design of the overall module

[0008] Therefore, the main purpose of the present invention is to solve the problem that the current barcode reading and decoding module is difficult to achieve extremely small size, extremely low power consumption, the most simplified components and extremely low cost
