[0052] In summary, the novel structure for placing the printer carbon ribbon not only improves the stability and reliability of the printer, but also enhances the user experience through optimized design. Compared with the prior art, the utility model has significant improvements and advantages in terms of structural design, operation convenience, and printing quality.

[0053] Specifically, the carbon ribbon assembly 110 includes:

[0054] A carbon ribbon placement rack 111, which is horizontally arranged inside the printer main body 100;

[0055] A carbon ribbon unwinding reel 112, which is horizontally arranged on one side of the carbon ribbon placement rack 111, and first gears 115 are arranged at both ends where the carbon ribbon unwinding reel 112 extends out of the carbon ribbon placement rack 111;

[0056] A carbon ribbon winding reel 113, which is horizontally arranged on the other side of the carbon ribbon placement rack 111, and second gears 116 are arranged at both ends where the carbon ribbon winding reel 113 extends out of the carbon ribbon placement rack 111.

[0057] It can be seen that the carbon ribbon placement rack 111, the carbon ribbon unwinding reel 112, and the carbon ribbon winding reel 113 together constitute the core part of the carbon ribbon assembly 110, enabling the carbon ribbon to smoothly transfer from the unwinding reel to the winding reel during the printing process, ensuring the continuity and stability of printing.

[0058] Specifically, the carbon ribbon assembly 110 further includes:

[0059] A carbon ribbon tensioning device, which is located between the carbon ribbon unwinding reel 112 and the carbon ribbon winding reel 113. One end of the carbon ribbon tensioning device is connected to the carbon ribbon placement rack 111, and the other end is connected to the carbon ribbon unwinding reel 112.

[0060] Specifically, the carbon ribbon tensioning device includes:

[0061] A tensioning wheel and a tensioning spring. The tensioning wheel is located between the carbon ribbon unwinding reel 112 and the carbon ribbon winding reel 113. The tensioning spring is located on the side of the tensioning wheel away from the carbon ribbon unwinding reel 112. One end of the tensioning spring is connected to the carbon ribbon placement rack 111, and the other end is connected to the tensioning wheel.

[0062] It can be seen that the combination of the tensioning wheel and the tensioning spring can effectively adjust the tension of the carbon ribbon, ensuring that the carbon ribbon maintains an appropriate tension during the printing process and avoiding printing quality problems caused by excessive or insufficient tension. The tensioning wheel can flexibly adjust its position under the action of the spring to adapt to carbon ribbons of different thicknesses and lengths, thereby improving the adaptability and printing effect of the printer.

[0063] Specifically, the fixing component includes:

[0064] Fixing brackets 131, there are two of them. The two fixing brackets 131 are respectively located at both ends of the ribbon assembly 110. One end of the fixing bracket 131 is connected to the inner wall of the printer main body 100, and the other end of the fixing bracket 131 is connected to the ribbon assembly 110;

[0065] Drive gears 132, there are four of them. Every two form a set of drive gears 132. The two sets of drive gears 132 are respectively located at both ends of the ribbon placement rack 111, and are located at the bottom of the fixing bracket 131. And the first gear 115 and the second gear 116 extend into the interior of the fixing bracket 131 and mesh with the set of drive gears 132.

[0066] It can be seen that the design of the fixing bracket 131 and the set of drive gears 132 makes the positioning of the ribbon assembly 110 in the printer more stable. At the same time, the setting of the set of drive gears 132 ensures the synchronism of the ribbon during unwinding and rewinding, avoiding the phenomenon of ribbon slipping or jamming. The precise cooperation of the set of drive gears 132 makes the movement of the ribbon during printing smoother, thereby improving the printing accuracy and efficiency.

[0067] Specifically, the fixing component further includes:

[0068] Positioning rod 133, arranged vertically on the top of the fixing bracket 131. The positioning rod 133 is located on the side of the first gear 115 far from the card slot 114, and the positioning rod 133 is connected to the first gear 115.

[0069] It can be seen that the design of the positioning rod 133 further enhances the connection stability between the ribbon assembly 110 and the printer main body 100. The connection between the positioning rod 133 and the first gear 115 ensures that the ribbon assembly 110 can accurately align with the card slot 114 during installation and disassembly, thereby simplifying the operation process and reducing the risk of ribbon misalignment or damage caused by improper installation. In addition, the presence of the positioning rod 133 also makes the fixing of the ribbon assembly 110 in the printer more firm. Even during a long printing operation, it can maintain good stability and avoid the problem of ribbon misalignment caused by vibration or impact.

[0070] Specifically, the positioning component includes:

[0071] Positioning plates 134, there are two of them. The two positioning plates 134 are located at the bottom of the upper cover, and the two positioning plates 134 are respectively located on both sides of the upper cover. The positioning plates 134 are snap-connected to the card slot 114;

[0072] Contact members 165, located at one end of the positioning plate 134. The contact members 165 include a sleeve 1351 and an elastic shaft 1352 that can extend out of the bottom of the sleeve 1351.

[0073] It can be seen that the design of the positioning plate 134 makes the ribbon assembly 110 more convenient and accurate during installation and removal. The clamping connection between the positioning plate 134 and the card slot 114 ensures that the ribbon assembly 110 can be firmly fixed inside the printer body 100 when the upper cover is closed, preventing it from shifting during the printing process. At the same time, the design of the abutment 165 further improves the accuracy of positioning. The combination of the sleeve 1351 and the elastic shaft 1352 enables the abutment 165 to have a certain buffering effect when it contacts the positioning plate 134, avoiding hard collisions, thereby protecting the ribbon assembly 110 from damage.

[0074] Specifically, the positioning components also include:

[0075] There are two clamping heads 136 , which are located at the bottom of the upper cover and are arranged toward the inside of the carbon ribbon placement rack 111 ;

[0076] The connecting rod 137 is located in the middle of the two clamping heads 136 , and two ends of the two connecting rods 137 are connected to the two clamping heads 136 respectively.

[0077] It can be seen that the design of the clamp 136 further enhances the connection stability between the ribbon assembly 110 and the printer body 100. The arrangement of the clamp 136 toward the inside of the ribbon placement rack 111 reduces the risk of ribbon dislocation or damage due to improper installation. The presence of the clamp 136 also makes the ribbon assembly 110 more firmly fixed inside the printer, and even in long-term printing operations, it can maintain good stability and avoid the problem of ribbon dislocation caused by vibration or impact. The setting of the connecting rod 137 provides additional support for the clamp 136, ensuring that the clamp 136 can be firmly fixed inside the printer body 100 when the upper cover is closed. The middle part of the connecting rod 137 connects the two clamps 136, so that the clamp 136 can remain stable when subjected to external forces, avoiding displacement or deformation of the clamp 136. At the same time, the design of the connecting rod 137 also makes the disassembly process of the carbon ribbon assembly 110 inside the printer more convenient. The user only needs to operate the upper cover to easily remove or install the carbon ribbon assembly 110, which greatly improves the convenience of using the printer.

[0079] A paper feed port is provided at the front end of the printer body 100;

[0080] The paper outlet is located at the rear end of the printer body 100 .

[0081] Specifically, the new structure of printer ribbon placement also includes:

[0082] The key unit is located on one side of the front end of the printer main body 100.

[0083] It can be seen that the design of the paper inlet and outlet enables the printer to conveniently receive and output the printing medium, ensuring the smooth progress of the printing process. The paper inlet is located at the front end of the printer main body 100, facilitating the user to put printing paper or other media into the printer, while the paper outlet located at the rear end enables the printed paper to be discharged smoothly, avoiding problems such as paper jams or misaligned papers. This front-rear design layout makes the operation of the printer more intuitive and convenient. The user does not need to worry about the paper entry and exit issues and can focus on the setting and execution of the printing tasks.

[0084] The design of the key unit provides an interface for the user to interact with the printer. Located on one side of the front end of the printer main body 100, the key unit usually includes a power switch, a print start button, function selection keys, etc. The user can easily control the startup, stop, and setting of various printing parameters through these keys. The design of the key unit fully considers the ergonomic principles, ensuring that the user can operate comfortably.
