Scanning device and scanning method for scanning bar code invoice

Abstract

The invention discloses a scanning device and a scanning method for a bar code invoice, which are used for scanning a bar code of the bar code invoice. The scanning device comprises a scanning module, a signal shaping module and a decode outputting module, wherein the scanning module is used for optically scanning a bar code sign of the bar code invoice and converting an optical signal of a bar code and bar blank pattern into an electric signal; the signal shaping module is used for amplifying the electric signal generated by the scanning module through a circuit to generate an analog signal and filtering and shaping the analog signal to form a square wave signal corresponding to the analog signal; the decode outputting module is used for interpreting the square wave signal formed by the signal shaping module into a digital signal which can be directly accepted by a computer. According to the scanning device and the scanning method disclosed by the invention, the scanning for bar codes in notes such as various bar code invoices, air tickets, train tickets and bus tickets is realized, the authenticity of the invoices can be detected, financial reimbursement, accounting and auditing of users are facilitated, financial management of the users is enabled to become efficient and accurate and the consumption of labor force and financial resources is reduced.

Description

technical field [0001] The present invention relates to a scanning device and method, in particular to a barcode invoice scanning device and method. Background technique [0002] Barcode scanners currently on the market include small drum barcode scanners, CCD readers, laser scanners, platform barcode scanners, and image-based red light barcode readers. They are widely used in commercial POS cashier systems, express warehousing logistics, Books, clothing, medicine, banking, insurance, communications and many other fields, but they can only be used to scan barcodes on various commodities and logistics express delivery, and have not been applied to the field of invoices, and cannot scan barcodes on invoices. At present, the financial management of enterprises and institutions is still manual reimbursement and accounting, resulting in heavy workload, low efficiency, and relatively low accounting accuracy. Therefore, it is necessary to propose a barcode invoice scanning technol...
