Description

Technical Field

[0001] This utility model relates to the field of cash register technology, and in particular to a cash register with a concealed wiring structure. Background Technology

[0002] With the popularization of mobile payment, desktop cash registers with barcode scanning modules and cash register devices used in conjunction with electronic scales have been widely used in many places, such as large supermarkets, restaurants, and retail stores such as cake shops, meat shops, fruit shops, and dry goods stores that have single-item management. Desktop cash register devices are generally set up at the checkout. For desktop POS systems, driven by the need for simplified operation for cashiers, improved user experience, and the trend towards self-checkout, and in order to save space and achieve efficient transactions, POS systems are integrating more and more electronic components or external devices. These include barcode scanners, receipt printers, keyboards, displays that allow both cashier operation and customer information about goods, handheld barcode scanners for scanning large or heavy items, and smart cameras for image or facial recognition. As the integration increases, so does the number of cables connecting these devices. This increased cable density leads to clutter, tangles, and wear, affecting the normal operation of the POS system and potentially hindering both cashiers and customers. Furthermore, the messy cable accumulation significantly impacts the aesthetics of the POS system. Therefore, it is necessary to conceal and organize the growing number of cables.

[0003] Furthermore, when POS systems are used in supermarkets or retail stores, items sometimes need to be weighed before payment. Therefore, in such applications, POS systems often need to be equipped with electronic scales for payment. As measuring instruments, the integrity of the lead seal is a core criterion for judging the quality of electronic scales. A lead seal is a sealing device that uses a physical locking mechanism to prevent tampering; its core function is to verify whether items have been opened without authorization during transportation or use. According to the Customs Law, opening or damaging a lead seal without customs permission is illegal. The 2025 industry standard explicitly requires lead seal products to have anti-technical tampering characteristics. For POS systems equipped with electronic scales, the electronic scales themselves must also be designed with lead seals to meet industry standards and legal requirements. Summary of the Invention
