Description

Technical Field

[0001] This utility model relates to the field of cash register equipment technology, and in particular to a dual-screen cash register equipment. Background Technology

[0002] Snack shops are stores specializing in the sale of snacks. They are popular with consumers due to the wide variety of snacks available and their affordable prices. Currently, snack shops use manual checkout; after customers select their snacks, a cashier processes the payment at the checkout counter.

[0003] Currently, snack shops typically have multiple (usually around three) POS machines. However, customer traffic in most snack shops varies significantly throughout the day, generally being lower during the day and higher at night. Therefore, snack shops employ fewer cashiers during the day and more at night to accommodate the varying customer volume. For example, they might have only one or two cashiers during the day, while employing three or four at night.

[0004] However, the number of customers during the day varies and is intermittent. Sometimes, when there are many customers but only one or two cashiers, customers often have to wait in long lines, which can easily lead to a loss of customer traffic. On the other hand, during the quieter part of the day, when there is no need for cashiers to handle transactions, self-service checkout machines would be more efficient.

[0005] However, existing self-checkout machines are relatively large machines. These machines are bulky and require a significant amount of space to place, typically used in large supermarkets, and are not suitable for snack shops. This is especially true for smaller snack shops, where space is already limited, leaving no room for self-checkout machines. Furthermore, manual checkout by cashiers is significantly more efficient than self-checkout. When there are many cashiers, relying on them can significantly improve checkout efficiency, making self-checkout machines redundant. Therefore, self-checkout machines used in large supermarkets are not suitable for snack shops.

[0006] When there are fewer cashiers during the day, snack shops usually only have one or two POS machines in use, while the others are idle. If the other idle POS machines are put into use when there are more customers during the day, it will not increase the cost or take up extra space in the store, and can significantly improve the problem of long queues.

[0007] Therefore, how to provide a new type of POS device to conduct POS settlement more flexibly and improve settlement efficiency is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0008] To address the aforementioned technical problems, this utility model provides a dual-screen POS device, where both the main and secondary screens are touchscreens. Cashiers and customers can perform payment and settlement through the main and secondary screens respectively, enabling both manual and self-service checkout modes. During normal checkout operations, cashiers can operate the main screen for manual processing, while when there are fewer cashiers, customers can use the secondary screen for self-service settlement. This allows for more flexible payment options and improves efficiency. It also allows for more flexible use of idle POS equipment in the store, avoiding excessively long customer queues.

[0061] This utility model provides a dual-screen POS device, comprising a main body and screens; the screens include a main screen and a secondary screen; the main screen is located on one side of the main body and electrically connected to it; the secondary screen is located on the other side of the main body and electrically connected to it; both the main screen and the secondary screen are touch screens; the secondary screen is rotatably connected to the main body via a connecting bracket, and a data collection device is provided on the secondary screen. Both the main screen and the secondary screen in this dual-screen POS device are touch screens, allowing customers to control the checkout process through the secondary screen, enabling self-service checkout. During normal checkout, cashiers can manually process transactions through the main screen, while when there are fewer cashiers, customers can self-checkout through the secondary screen, thus allowing for more flexible checkout processes, improving efficiency, and making more flexible use of idle POS equipment in the store.

[0062] Please refer to the following: Figures 1 to 5In one embodiment, a dual-screen POS device 100 is provided, mainly as an improvement on small POS devices used in shops such as snack stores. It is a small, dual-screen POS device. Both the main screen and the secondary screen of the dual-screen POS device 100 are touchscreens, allowing for manual checkout by cashiers or self-service checkout by customers, improving the flexibility of checkout and settlement, thus making better use of idle POS equipment and increasing settlement efficiency.

[0063] The dual-screen POS device 100 includes a main body 10 and a screen 20. The screen 20 includes a main screen 21 and a secondary screen 20. The main screen 21 is located on one side of the main body 10 and electrically connected to it. The main body 10 contains a main control module, which includes a processor and other structures for processing and outputting relevant information. In this application, the electrical connection of a component to the main body 10 mainly refers to its electrical connection to the main control module within the main body 10. This connection can be achieved via a cable, a well-known technique in the field, and will not be elaborated upon here. The secondary screen 22 is located on the other side of the main body 10 and electrically connected to it. Both the main screen 21 and the secondary screen 22 are touchscreens. The secondary screen 22 is rotatably connected to the main body 10 via a connecting bracket 30, and a data acquisition device 40 is mounted on the secondary screen 22. In other words, in this embodiment, the secondary screen 22 is a touch screen instead of a simple display screen, and the secondary screen 22 can also rotate relative to the main body 10 of the cash register, so that customers can adapt the position of the secondary screen 22 according to their own needs.

[0064] The acquisition device 40 refers to a device capable of acquiring sound signals and / or image signals, specifically a microphone and / or a camera.

[0065] Understandably, existing small POS systems used in snack shops and similar stores also employ a dual-screen structure. However, only the main screen uses a touchscreen, allowing interaction with the main control module for checkout operations. The secondary screen uses a standard display, used only to synchronously display some information during checkout to keep customers informed of the process. Snack shops typically have multiple POS systems, but during the day when there are fewer cashiers, only one or two are in use, while the others remain idle. During peak daytime hours, this can lead to long queues. Utilizing the idle POS systems would effectively solve these problems. The side with the main screen is usually the cashier's checkout area, often containing cash boxes and other items, preventing customers from directly using the idle POS systems on that side.

[0066] In this embodiment, both the main screen 21 and the secondary screen 22 of the dual-screen POS device 100 are touchscreens, allowing customers to interact directly with the main body 10 of the POS device on the secondary screen 22 to complete the checkout process. In other words, the dual-screen POS device 100 can perform checkout on both the main screen 21 and the secondary screen 22, enabling both manual and self-service checkout, thus providing greater flexibility. For example, during the day when there are fewer cashiers, the idle dual-screen POS devices 100 can be switched to self-service checkout mode, allowing one cashier to monitor multiple devices simultaneously. Additionally, when there are insufficient staff but inventory needs to be replenished, self-service checkout mode can also be used. Since snack shops have higher customer traffic and more cashiers at night, manual checkout mode can be switched to, significantly improving checkout efficiency and reducing labor costs. Meanwhile, the secondary screen 22 is rotatably connected to the main body 10 of the POS device via the connecting frame 30, allowing customers to adjust the position of the secondary screen 22 according to their needs, better meeting the usage requirements of different customers. Additionally, a data acquisition device 40 is provided to collect sound and / or images during self-checkout, recording customer behavior and preventing disputes.

[0067] Specifically, in one embodiment, both the main screen 21 and the secondary screen 22 can be electrically connected to the main control module via cables, thereby improving the stability of information transmission.

[0068] Preferably, in one embodiment, the main body 10 of the POS device includes a base 11 and a column 12 disposed on the base 11, and the connecting frame 30 includes a first frame 31 and a second frame 32. The first frame 31 is rotatably connected to the column 12, and the second frame 32 is fixed to the sub-screen 22, and the second frame 32 is rotatably connected to the first frame 31. That is, in this embodiment, there are at least two rotatable connection points between the main body 10 of the POS device and the sub-screen 22, thereby allowing the sub-screen 22 to be rotated and adjusted more flexibly.

[0069] Preferably, in one embodiment, a mounting bracket 121 is provided on the back side of the column 12, and the first frame 31 is rotatably connected to the mounting bracket 121 via a first rotating shaft 33, and the first rotating shaft 33 is arranged vertically. That is, in this embodiment, the first frame 31 can swing laterally relative to the column 12, thereby causing the sub-screen 22 to swing laterally, thus realizing the adjustment of the sub-screen 22 in the left and right horizontal position.

[0070] Preferably, in one embodiment, the second frame 32 is rotatably connected to the first frame 31 via a second rotating shaft 34, and the second rotating shaft 34 is arranged horizontally. That is, in this embodiment, the second frame 32 can swing vertically relative to the first frame 31, thereby causing the sub-screen 22 to swing vertically, thus realizing the adjustment of the vertical position of the sub-screen 22.

[0071] Preferably, in one embodiment, the second frame 32 is rotatably connected to the first frame 31 via two second rotating shafts 34, and the two second rotating shafts 34 are spaced apart from each other in the lateral direction. This structure improves the reliability of the connection between the second frame 32 and the first frame 31, and also makes the second frame 32 more balanced in terms of force, so that it is not easy to tilt to one side under long-term use.

[0072] Preferably, in one embodiment, the first frame 31 includes a connecting portion 311 and a mounting portion 312. The connecting portion 311 is rotatably connected to the mounting frame 121 via a first rotating shaft 33, and the connecting portion 311 is provided with two connecting plates 3111, which are spaced apart vertically. The first rotating shaft 33 passes through the two connecting plates 3111. This structure can further improve the connection reliability between the first frame 31 and the mounting frame 121. The mounting portion 312 is connected to the end of the connecting portion 311 away from the first rotating shaft 33, and the mounting portion 312 is provided with two mounting plates 3121, which are spaced apart laterally. The second frame 32 is provided with two connecting arms 321. One connecting arm 321 is rotatably connected to a mounting plate 3121 via a second pivot 34, and the other connecting arm 321 is rotatably connected to another mounting plate 3121 via another second pivot 34. This structure can further improve the connection reliability between the second frame 32 and the first frame 31, and also make the force on the second frame 32 more balanced.

[0073] Specifically, in one embodiment, both the main screen 21 and the secondary screen 22 are high-resolution screens of 1920*1080, and the main screen 21 is set to landscape mode, while the secondary screen 22 is set to portrait mode.

[0074] Preferably, in one embodiment, the dual-screen POS device 100 further includes a barcode scanning and ticketing module 60, which includes a receipt printer 61 and a barcode scanner 62. A base 611 is provided on the bottom side of the receipt printer 61, and the barcode scanner 62 is placed on the base 611. The receipt printer 61 and the barcode scanner 62 are communicatively connected to the POS device body 10. The receipt printer 61 is mainly used for printing receipts, while the barcode scanner 62 is mainly used for scanning QR codes on goods to identify them. In other words, in this embodiment, the receipt printer 61 and the barcode scanner 62 are designed as a combined module, making it convenient for cashiers and customers to use.

[0075] Preferably, in one embodiment, the main screen 21 and the secondary screen 22 are disposed on both sides of the column 12, and the ticket printer 61 is movably placed on the base 11. That is, in this embodiment, the ticket printer 61 is not fixed to the main body 10 of the cash register device, but can be removed and moved; it is a movable structure. This allows the scanning and ticketing module 60 to be placed in different positions according to different cash register modes, facilitating operation by cashiers and customers. For example, in the cashier's manual cash register mode, the scanning and ticketing module 60 can be placed below the main screen 21 for cashier use, while in the customer self-service cash register mode, the scanning and ticketing module 60 can be placed below the secondary screen 22 for customer self-service scanning. More preferably, in one embodiment, the base 611 has a receiving slot 6111, and the barcode scanner 62 is placed in the receiving slot 6111. A first magnetic suction element is provided in the receiving slot 6111, and a second magnetic suction element 621 matching the first magnetic suction element is provided on the barcode scanner 62. That is to say, in this embodiment, the barcode scanner 62 can be firmly fixed on the base 611 by magnetic attraction, thereby improving the reliability of the position of the barcode scanner 62, and when it is necessary to remove the barcode scanner 62, it can be easily removed.

[0076] Specifically, in one embodiment, the first magnetic component can be a magnet, while the second magnetic component 621 can be made of any material that can be attracted by a magnet, such as iron. Since the barcode scanner 62 can be removed separately, cashiers or customers can place the barcode scanner 62 into the base 611 to scan the goods, or remove the barcode scanner 62 to scan the goods, as needed.

[0077] More preferably, in one embodiment, the barcode scanner 62 is wirelessly connected to the main body 10 of the POS device, for example, the barcode scanner 62 achieves wireless communication connection with the main body 10 of the POS device via Bluetooth. Wireless connection facilitates the removal of the barcode scanner 62 and allows it to scan and identify products more flexibly.

[0078] Specifically, in one embodiment, the receipt printer 61 is connected to the main body of the cash register 10 via a cable, thereby better ensuring the stability of communication.

[0079] Preferably, in one embodiment, the base 611 is provided with a wireless charging module, thereby enabling wireless charging of the barcode scanner 62.

[0080] Please refer to the following: Figure 6 and Figure 7 Preferably, in another embodiment, the main screen 21 is disposed on the front side of the column 12, and the secondary screen 22 on the back side. The ticket printer 61 is fixed on the base 11, and the ticket outlet of the ticket printer 61 faces the side of the column 12 (e.g., as shown). Figure 7 In the illustrated embodiment, the ticket outlet of the receipt printer 61 faces to the left. That is, in this embodiment, the receipt printer 61 is fixed to the main body 10 of the cash register and cannot be moved. While a movable structure facilitates checkout for cashiers and customers, it requires frequent repositioning of the receipt printer 61, which inevitably leads to bumps and knocks, potentially damaging the printer. This embodiment, by fixing the receipt printer 61 to the base 11, better avoids damage. Furthermore, the fact that the ticket outlet of the receipt printer 61 faces the side of the column 12 also effectively accommodates both manual and self-service checkout modes, making it convenient for cashiers and customers to retrieve receipts.

[0081] Preferably, in one embodiment, the acquisition device 40 adopts a behavior monitoring camera, which is equipped with a wide-angle lens and a microphone to realize the acquisition of images and audio.

[0090] The ticket printer 61* can be placed on the base 11 or fixed on the base 11. When the ticket printer 61* is fixed on the base 11, the ticket outlet of the ticket printer 61* also faces the side.

[0091] Specifically, in such Figure 8 In the illustrated embodiment, the acquisition device 40 may use only a microphone without a camera. That is, in this embodiment, the acquisition device 40 is only used for acquiring sound signals. Preferably, in one embodiment, the acquisition device 40 has two independent microphones, which can be used to acquire sound signals from the cashier and the customer respectively. The two microphones are oriented in opposite directions: one faces towards the main screen 21 to acquire the cashier's sound signal, and the other faces away from the main screen 21 to acquire the customer's sound signal. This arrangement improves the independence of sound acquisition and avoids interference. The housing of the acquisition device 40 may have microphone ports on both sides to accommodate the two microphones for sound signal acquisition.

[0092] The dual-screen POS device 100 supports both cashier-operated and self-service checkout modes. In the conventional cashier-operated mode, the barcode scanning and ticketing module 60 is located below the main screen 21 for cashier use. Customers choose their preferred payment method at checkout. When switching to self-service mode via the self-developed system, the barcode scanning and ticketing module 60 can be placed facing the customer. Customers input the items they wish to purchase into the system using the barcode scanner 62, which can scan barcodes according to the size of the items. Customers can also choose their preferred payment method. This POS device, which allows for both cashier-operated and self-service checkout, significantly improves checkout convenience and reduces space requirements. During peak hours, it alleviates checkout pressure and reduces customer loss, while also lowering labor costs.
