Description

Technical Field

[0001] This utility model belongs to the field of cash register technology, and in particular relates to a cash register and printing all-in-one machine. Background Technology

[0002] Currently, supermarkets, stores, and other retail establishments frequently use cash registers. Existing cash registers typically display product information on a main screen, then collect payment via QR code or scanning a QR code, and finally use an external printer to print the receipt. In current technology, after a customer pays, a receipt detailing each item is printed on it for the customer to verify the purchased goods and prices, serving as proof of purchase. However, existing receipt printing has the following problems: First, the receipt nozzle faces inwards, making it difficult for customers to check immediately; they often only have time to compare it at home, leading to high time costs for correcting errors. Second, existing receipt printing often requires manual tearing, which is unsightly and inefficient. Third, current cash register, printing, and payment systems often require multiple devices, occupying a large space and providing a poor customer experience. Utility Model Content

[0003] In summary, to overcome the shortcomings of the existing technology, this utility model provides a cash register and printer all-in-one machine.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cash register and printer all-in-one machine, comprising a main body, a main display screen, and a printing module. The printing module includes a housing and a receipt printer disposed within the housing. A connecting rod is provided on the inner side of the housing, and an insertion hole adapted to the connecting rod is provided on one side of the main body. The main body and the housing are detachably connected by fasteners cooperating with the connecting rod. A ticket outlet is provided on the rear side of the housing. A partition dividing the housing into left and right sides is provided inside the housing. A paper roll shaft, a paper take-up holder, a rubber roller, and a thermal element are provided on the outer side of the partition. A pressure roller assembly is provided between the rubber roller and the ticket outlet, and a cutter assembly is provided between the pressure roller assembly and the ticket outlet. A drive assembly for driving the paper receiving rack and the rubber roller to rotate, and a first circuit board for controlling the drive assembly, the thermal element, and the cutter assembly are provided inside the partition. An NFC payment module is provided at the rear of the main body. A mounting frame is provided inside the main body, and a main circuit board is mounted on the mounting frame. A wire outlet hole for electrical connection with the main circuit board is provided inside the housing corresponding to the position of the first circuit board. The main display screen and the NFC payment module are respectively electrically connected to the main circuit board.

[0005] By adopting the above technical solution, the core functions required for cashiering (display, processing, printing, and contactless payment) are integrated into one unit, avoiding the problems of messy cables and excessive counter space occupation in traditional separate devices. Placing the NFC module on the back of the main unit is ergonomically sound, allowing customers to easily "tap" their phones or credit cards near the back of the main unit for a smooth payment process without interfering with the cashier's operating area. Through the cooperation of connecting rods and sockets, and with the aid of fasteners, the entire printing module can be detached from the main unit as an independent unit. When the printer jams, runs out of paper, or needs to replace consumables (such as thermal elements), the cashier can easily remove it. Maintenance personnel can simply open the outer door of the casing, greatly shortening maintenance time and reducing business interruption losses. The partition inside the casing divides the space into a "mechanical area" (outer side, containing paper rolls, rubber rollers, etc.) and a "drive control area" (inner side, containing drive components and the first circuit board), preventing paper scraps and dust from contaminating the internal precision motors and circuit boards, and isolating the mechanical moving parts from the circuits, reducing the risk of accidental contact during maintenance. At the same time, the ticket outlet is located on the rear side of the casing, allowing customers to check their tickets before paying via the NFC module, improving the customer experience. The automatic ticket cutting component further facilitates customer use.

[0006] The present invention further includes: the NFC payment module includes an upper rear cover detachably connected to the main body; the upper rear cover includes an outer plate disposed outside the main body and an installation part disposed inside the main body; a small display screen and a sensing component are disposed on the rear side of the outer plate; the small display screen and the sensing component are arranged vertically; a communication component, a control component, and a power supply component are disposed inside the installation part and are electrically connected to the small display screen and the sensing component; the control component is electrically connected to the main circuit board.

[0007] By adopting the above technical solution, the NFC module, as a whole (including the upper and lower cover, small display screen, sensing components, etc.), is detachably connected to the host, facilitating maintenance and assembly and reducing maintenance costs. The communication components, control components, and power components are protected inside the host casing, avoiding the risks of daily bumps, liquid splashes, and dust intrusion, while shortening the connection path with the main circuit board and making signal transmission more stable. The NFC payment module has its own control component, which is dedicated to handling payment communication, encryption and decryption, and data display, reducing the burden on the main circuit board and making payment transactions faster and more secure. The small display screen is used to display feedback information such as transaction amount and payment status ("Please swipe card", "Payment successful", "Please try again"), which is convenient for customers. After seeing the screen prompt, the user can swipe the card or touch the phone in the area below (through the sensing components). The small display screen and sensing components are distributed vertically, forming an intuitive visual-motor guidance, while optimizing the design layout and making it more aesthetically integrated into the main body.

[0008] The present invention further includes: elastic sealing blocks are provided between the two sides of the mounting part and the inner wall of the main body.

[0009] By adopting the above technical solution, simply align the mounting part of the upper rear cover with the space inside the main body and push it inward. The elastic sealing blocks on both sides will deform elastically under pressure, facilitating quick assembly and positioning. Then, the mounting part can be detachably connected to the mounting bracket by tightening bolts. There is no need to position the upper rear cover with one hand and tighten the bolts with the other hand, making the operation convenient, time-saving, and labor-saving. At the same time, it plays a role in buffering and shock absorption, protecting the delicate electronic components inside; it is also dustproof and moisture-proof, protecting the internal components.

[0010] The present invention further includes a speaker mounted on the mounting bracket, the speaker being electrically connected to the main circuit board.

[0011] By adopting the above technical solutions, the built-in integration saves space; voice broadcasting makes it convenient for customers and cashiers to quickly understand the payment status.

[0012] The present invention further includes: a socket assembly on the rear side of the main body, the socket assembly including a cash drawer socket and a sensor socket, and a second circuit board electrically connected to the socket assembly on the mounting bracket, the second circuit board being electrically connected to the main circuit board and the first circuit board respectively.

[0013] By adopting the above technical solutions, the circuit is partitioned, the internal wiring is optimized, heat dissipation is fast, maintenance is convenient, and stability is higher; a sensor port is set up, which can be quickly connected to electronic scales or other devices, providing expandability and ease of use.

[0014] The present invention further comprises: a lower rear cover hinged to the rear side of the main body, a gripping part provided on the lower rear cover, a mounting recess provided on the front side of the lower rear cover, a magnet provided in the mounting recess, and a connecting post for attracting the magnet provided on the rear side of the mounting bracket corresponding to the position of the magnet.

[0015] By adopting the above technical solution, the lower rear cover is transformed from a "baffle" that requires tools to disassemble into a "maintenance door" that can be easily opened and closed by hand and has a self-locking function. Its core advantage lies in achieving a perfect combination of tool-free and quick opening and closing, which greatly facilitates daily circuit inspection, dust cleaning or replacement of internal modules. The specific embodiments of this utility model are described below with reference to the accompanying drawings and examples. Attached Figure Description
