Description

Technical Field

[0001] This utility model relates to the field of desktop cash register technology, specifically to a desktop cash register with a modular design for the printing device. Background Technology

[0002] Desktop cash registers are widely used in various supermarkets, shopping malls and other business establishments. Because they need to print shopping or receipts, desktop cash registers are equipped with printing devices. Currently, the printing module is not integrated into a single unit. That is, the various components that make up the printing device are directly fixed inside the cash register casing. As a result, when after-sales maintenance is required for the components involved in the printing device, a large number of screws need to be removed before the parts that need to be repaired or replaced can be disassembled. After the repair is completed, a lot of time is spent reinstalling them on the cash register casing. This is time-consuming, labor-intensive and extremely inconvenient for after-sales service.

[0004] The technical solution is as follows: A cash register equipped with a modular printing device includes a housing, a mounting bracket on the housing, a PCB board and a printing device inside the housing; the printing device includes a paper tray inside the housing, a paper tearing cutter on the upper part of the paper tray, a printer core on the back of the paper tray and below the paper tearing cutter, and a paper tray cover; the mounting bracket includes two parallel mounting arms, and an upper connecting plate and a lower connecting plate perpendicular to the inner side of each mounting arm are provided; the paper tray includes two paper tray side plates, and an upper connecting plate and a lower connecting plate are provided on the back of each paper tray side plate, and the upper connecting plate and the lower connecting plate are located on the same mounting arm; the paper tray side plates are detachably connected to the upper connecting plate and the lower connecting plate by screws.

[0005] Preferably, the upper part of the paper tray is provided with a base connected to it by screws, and the paper tearing cutter is fixed on the upper surface of the base.

[0006] Preferably, the lower back of the paper compartment cover is provided with two connecting plates perpendicular to it, and two connecting notches are provided at the lower part of the paper compartment; the free ends of the two connecting plates extend into the two connecting notches respectively and are hinged to the outer shell.

[0007] Preferably, the mounting bracket further includes an upper mounting plate fixedly connected to the two mounting arms, and an adapter plate is provided on the upper surface of the upper mounting plate, wherein the adapter plate is provided with a plurality of external pins.

[0008] Preferably, it also includes a cover plate with a square hole inside, and the adapter plate is located inside the square hole.

[0009] Preferably, a fixing plate is provided on the bottom surface of the upper mounting plate, and two mounting parts that extend into the outer shell and are fixedly connected to the outer shell are fixed on the bottom surface of the fixing plate.

[0010] Technical advantages: This utility model integrates the paper tray, paper tearer, and printer core of the printing device into a whole, and fixes the whole to the mounting bracket in a detachable manner. When the printing device malfunctions during use, the printing device can be quickly disassembled to repair or replace the damaged parts, and then quickly installed on the mounting bracket. Compared with the prior art, this utility model is conducive to improving after-sales maintenance efficiency and is extremely convenient for after-sales maintenance. Attached Figure Description

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-5As shown, this utility model embodiment provides a cash register equipped with a modular printing device, including a housing 1, a mounting bracket 2 on the housing, a PCB board 3 inside the housing, and a printing device; the printing device includes a paper tray 4 inside the housing, a paper tearing cutter 5 on the upper part of the paper tray, a printer core 6 on the back of the paper tray and below the paper tearing cutter, and a paper tray cover 7; the mounting bracket 2 includes two parallel mounting arms 201, with an upper connecting plate 201a and a lower connecting plate 201b perpendicular to the inner side of each mounting arm; the paper tray 4 includes two paper tray side plates 401, with an upper connecting plate and a lower connecting plate on the back of each paper tray side plate, and the upper and lower connecting plates are located on the same mounting arm; the paper tray side plates are detachably connected to the upper and lower connecting plates by screws. The paper tray 4, paper tearing cutter 5, and printer core 6 are all commercially available standard parts.

[0019] Specifically, such as Figure 3 As shown, the upper part of the paper tray 4 is provided with a base 8 connected to it by screws, and the paper tearing cutter 5 is fixed on the upper surface of the base.

[0020] To achieve a rotatable connection between the paper tray cover and the outer casing 1, such as Figure 3 As shown, the lower back of the paper compartment cover 7 has two perpendicular transition plates (not shown), and the lower part of the paper compartment 4 has two transition notches 402. The free ends of the two transition plates extend into the two transition notches and are hinged to the outer shell 1. Specifically, the bottom surface of the outer shell 1 has two parallel vertical plates 101, and each vertical plate has a transverse hinge post 102 on its outer side. The free ends of the two transition plates are hinged to the two hinge posts, that is, the free end of each transition plate is hinged to one of the transverse hinge posts.
