DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0045] Please refer to Figure 1 and Figure 2 A printer 100 provided in the embodiment of the present application, the printer 100 includes a body 10, a carbon tape cartridge 20, a first radio frequency assembly 30 and a second radio frequency assembly 40, the body 10 includes a body body 11 and a metal support 12 arranged on the body body 11, the body body 11 has an assembly cavity 111, the metal support 12 has a passage 121 which communicates with the assembly cavity 111, the carbon tape cartridge 20 is arranged in the assembly cavity 111, the first radio frequency assembly 30 is arranged on the metal support 12, and the first radio frequency assembly 30 is located at one end of the passage 121, the second radio frequency assembly 40 is arranged on the carbon tape cartridge 20, and the second radio frequency assembly 40 is located at the other end of the passage 121, so that the second radio frequency assembly 40 can communicate with the first radio frequency assembly 30 through the passage 121.

[0046] It can be understood that the inside of the body 11 has an assembly cavity 111, and a plug-in hole is formed on the outer surface of the body 11, which communicates with the assembly cavity 111, so that the carbon tape box 20 can be detachably inserted into the assembly cavity 111 from the plug-in hole, so that the carbon tape box 20 can be conveniently replaced. The metal support 12 can be provided on the outer surface of the body 11, so that the metal support 12 can play a protective role for the body 11 as an external structure of the body 11, and the channel 121 can communicate with the assembly cavity 111. The end of the channel 121 close to the assembly cavity 111 is defined as the first end 61, and the end of the channel 121 away from the assembly cavity 111 is defined as the second end 62. The first end 61 and the second end 62 of the channel 121 are opposite ends.

[0047] The first radio frequency component 30 can be provided on the metal support 12, and the first radio frequency component 30 is located at the first end 61 of the channel 121, that is, the projection of the first radio frequency component 30 on the metal support 12 covers the first end 61 of the channel 121. The second radio frequency component 40 can be provided on the carbon tape box 20, and the second radio frequency component 40 is located at the second end 62 of the channel 121, that is, the projection of the second radio frequency component 40 close to the inner wall of the channel 121 can cover the second end 62 of the channel 121. Thus, the second radio frequency component 40 and the first radio frequency component 30 can be located at opposite ends of the channel 121, so that the radio frequency signal emitted by the second radio frequency component 40 can communicate with the first radio frequency component 30 through the channel 121.

[0048] In this embodiment, the channel 121 is a straight channel 121, so that there is no metal piece between the second radio frequency component 40 and the first radio frequency component 30. It can prevent the second radio frequency component 40 and the first radio frequency component 30 from being interfered by the metal piece during communication, and can increase the sensitivity of the communication signal between the second radio frequency component 40 and the first radio frequency component 30.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments, the first radio frequency component 30 and the channel 121 are provided on the bottom of the metal support 12, and the second radio frequency component 40 is provided on the bottom of the carbon tape box 20.

[0050] In combination with Figure 3As shown, the side of the main body 11 with the paper feed opening 112 is the top of the main body 11, and the side of the main body 11 opposite to the side with the paper feed opening 112 is the bottom of the main body 11. When printing label paper, the printed label paper will extend outward from the main body 11 through the paper feed opening 112. The metal bracket 12 is covered and disposed on the outer surface of the main body 11, and the part of the metal bracket 12 located at the bottom of the main body 11 is the bottom of the metal bracket 12. When the ribbon cartridge 20 is disposed in the assembly cavity 111, the side of the ribbon cartridge 20 facing the bottom of the main body 11 is the bottom of the ribbon cartridge 20.

[0051] It should be noted that during printing, the ribbon on the ribbon cartridge 20 needs to be fed towards the paper feed opening 112, or in other words, towards the top of the printer body 11, so that the ribbon can contact the label paper at the paper feed opening 112. This allows the printed label paper to smoothly extend outward from the paper feed opening 112. Therefore, the ribbon is located at the top of the ribbon cartridge 20 during printing, making it inconvenient to install the second RF component 40 at the top of the ribbon cartridge 20. Setting the second RF component 40 at the bottom of the ribbon cartridge 20 facilitates its installation. Setting both the first RF component 30 and the channel 121 at the bottom of the metal bracket 12 facilitates communication between the second RF component 40 and the first RF component 30 through the channel 121.

[0052] Please see Figure 1 In some embodiments, both channel 121 and the first radio frequency component 30 are located in the middle of the metal bracket 12.

[0053] It should be noted that channel 121 and the first radio frequency component 30 are located at the bottom of the metal bracket 12, and channel 121 and the first radio frequency component 30 are located in the middle of the bottom of the metal bracket 12. This makes the relative position between the first radio frequency component 30 and other components on the main body 11 relatively moderate. That is, the distance between the first radio frequency component 30 and any of the components will not be too large. Thus, the first radio frequency component 30 can be easily connected to other components on the main body 11 and play the role of line relay.

[0054] Please see Figure 1 and Figure 2 In some embodiments, the first radio frequency component 30 includes a first circuit board 31 and a first radio frequency coil 32. The first circuit board 31 is disposed on the metal bracket 12, the first radio frequency coil 32 is electrically connected to the first circuit board 31, and the first radio frequency coil 32 is disposed opposite to the channel 121.

[0055] Specifically, the first circuit board 31 can be connected to the metal bracket 12, and the first radio frequency coil 32 is electrically connected to the first circuit board 31, so that the first radio frequency coil 32 can be located at the first end 61 of the channel 121. The first radio frequency coil 32 is responsible for generating and receiving radio frequency signals, so that the radio frequency signals generated by the first radio frequency coil 32 can be transmitted to the second radio frequency component 40 through the channel 121, and the first radio frequency coil 32 receives the radio frequency signals generated by the second radio frequency component 40 through the channel 121. The first circuit board 31 is responsible for amplifying, modulating, demodulating and other processing of the radio frequency signals, which can further facilitate communication between the first radio frequency component 30 and the second radio frequency component 40.

[0056] Please see Figure 1 and Figure 3 In some embodiments, the printer 100 further includes a second circuit board 50, which is provided with a power switch and is disposed on the top plate of the metal bracket 12. The second circuit board 50 is electrically connected to the first circuit board 31 disposed at the bottom of the metal bracket 12.

[0057] In this embodiment, the metal bracket 12 extends to the top of the printer body 11, and the second circuit board 50 is located on the top of the metal bracket 12, so that the second circuit board 50 is set on the top of the printer body 11. The second circuit board 50 is equipped with a power switch, which can facilitate the user to start and stop the printer 100. The second circuit board 50 can also be electrically connected to the first circuit board 31, and the first circuit board 31 is set at the bottom of the metal bracket 12, so that the first circuit board 31 and the second circuit board 50 can be reasonably distributed around the printer 100, making the structure of the printer 100 more compact and facilitating the internal wiring of the printer 100.

[0058] Please see Figure 1 and Figure 3 In some embodiments, the first circuit board 31 and the second circuit board 50 are connected by a flexible circuit board 51.

[0059] It should be noted that, since the first circuit board 31 and the second circuit board 50 are located at the bottom and top of the printer body 11 respectively, the wiring connecting the first circuit board 31 and the second circuit board 50 needs to bend and extend along the outer surface of the printer body 11 from the bottom to the top. The flexible circuit board 51, being made of a soft material, can be bent and twisted, allowing it to adapt to complex installation space requirements. Connecting the first circuit board 31 and the second circuit board 50 via the flexible circuit board 51 ensures a more secure connection. Furthermore, the flexible circuit board 51 features high wiring density, allowing for more wiring to be arranged in a smaller space, which helps save internal space in the printer 100 and improves the printer 100's integration.

[0060] Please see Figure 1 and Figure 3 In some embodiments, the printer 100 further includes a cover 60, the first end 61 of which is rotatably connected to the main body 11, and the first end 61 and the second end 62 of the cover 60 are opposite ends. The main body 11 has a paper feed opening 112, and the second circuit board 50 and the second end 62 of the cover 60 are located on opposite sides of the paper feed opening 112.

[0061] Understandably, the first end 61 of the cover 60 is rotatably connected to the body 11, allowing the cover 60 to rotate relative to the body 10, so that the cover 60 can switch between a closed state and an open state. More specifically, when the cover 60 rotates toward the body 11 until it is closed, the cover 60 is in a closed state. When the cover 60 rotates away from the body 11 until it is set at an angle to the body 11, the cover 60 is in an open state.

[0062] In this embodiment, the second circuit board 50 is disposed on the top of the main body 11, and the paper feed opening 112 is also located on the top of the main body 11. If the second circuit board 50 and the cover 60 are disposed on the same side of the paper feed opening 112, the cover 60 will cover the second circuit board 50 when it is closed, making it inconvenient for the user to open and close the printer 100. However, by disposing the second circuit board 50 and the cover 60 on opposite sides of the paper feed opening 112, it is not only convenient for the user to open and close the printer 100, but also allows the second circuit board 50 to be disposed close to the first circuit board 31, facilitating the electrical connection between the first circuit board 31 and the second circuit board 50.

[0063] Please see Figure 3 In some embodiments, the printer 100 further includes a first sensor 70, which is disposed at the second end 62 of the cover 60 and is electrically connected to the first circuit board 31.

[0064] Specifically, the first sensor 70 is disposed at the second end 62 of the cover 60. When the cover 60 is closed, the first sensor 70 can be disposed opposite to the paper feed opening 112. The first sensor 70 can be used to detect the printing status of label paper, such as detecting whether there is label paper inside the printer 100 and detecting the number of label papers printed. The first sensor 70 and the second circuit board 50 are respectively located on opposite sides of the paper feed opening 112. Since the wire cannot pass through the paper feed opening 112, if the first sensor 70 and the second circuit board 50 are connected by a wire, the wire needs to be routed around the bottom of the main body 11, resulting in a very long wire connecting the first sensor 70 and the second circuit board 50. Therefore, connecting the first sensor 70 and the first circuit board 31 at the bottom of the main body 11 by a wire can reduce the length of the wire and facilitate wire routing.

[0065] Please see Figure 3 In some embodiments, the printer 100 includes a paper baffle 80 and a third radio frequency component 81. The paper baffle 80 is movably disposed in the paper tray of the printer body 11, and the third radio frequency component 81 is disposed on the paper baffle 80 and can be electrically connected to the first circuit board 31.

[0066] Optionally, the printer 100 includes two guide plates 80, which are movably disposed within the paper tray of the printer body 11. The two guide plates 80 are spaced apart along the width of the printer body 11, so that the two guide plates 80 can clamp the label paper roll in the paper tray and fix the label paper roll, making it convenient for the printer 100 to print labels. A third radio frequency component 81 is disposed on the guide plates 80, so that the third radio frequency component 81 can be used to detect the usage status of the label paper roll. When the label paper is used up, it can remind the user to replace the label paper roll.

[0067] Similarly, although the third RF component 81 and the second circuit board 50 are both located on the top of the main body 11, they are located on opposite sides of the paper feed opening 112. Since the line cannot pass through the paper feed opening 112, if the third RF component 81 and the second circuit board 50 are connected by a line, the line needs to go around the bottom of the main body 11, which would result in a very long line connecting the third RF component 81 and the second circuit board 50. Therefore, connecting the third RF component 81 to the first circuit board 31 at the bottom of the main body 11 by a line can reduce the length of the line and facilitate wiring.

[0068] Please see Figure 3In some embodiments, the printer 100 further includes a second sensor 90, which is disposed on the printer body 11 and the printer body 11 has a paper feed opening 112. The second sensor 90 and the second circuit board 50 are respectively located on opposite sides of the paper feed opening 112, and the second sensor 90 is electrically connected to the first circuit board 31.

[0069] Optionally, the second sensor 90 is disposed on the main body 11 and is positioned close to the paper feed opening 112, so that the second sensor 90 can detect the label paper extending out of the main body 11 from the paper feed opening 112. Since the second sensor 90 and the second circuit board 50 are located on opposite sides of the paper feed opening 112, in order to prevent the wiring from obstructing the paper output from the paper feed opening 112, the connecting wire on the second sensor 90 cannot be connected to the second circuit board 50 through the paper feed opening 112. Electrically connecting the connecting wire of the second sensor 90 to the first circuit board 31 at the bottom of the main body 11 can reduce the wiring difficulty and facilitate wiring.

[0070] Please see Figure 2 and Figure 4 In some embodiments, the metal bracket 12 is provided with a positioning post 122, which is located at the opening of the channel 121. The first circuit board 31 has a positioning groove 311, which is engaged with the positioning post 122.

[0071] Optionally, the positioning post 122 can be set at the edge of the opening of the channel 121, and the peripheral edge of the first circuit board 31 is provided with a positioning groove 311. When installing the first circuit board 31, the positioning post 122 can be engaged with the positioning groove 311, which can easily install the first circuit board 31 on the metal bracket 12 and prevent the first circuit board 31 from shaking.

[0072] In this embodiment, the metal bracket 12 is provided with two positioning posts 122. Both positioning posts 122 are located at the edge of the opening of the channel 121 and are arranged opposite to each other. The opposite two sides of the first circuit board 31 can be provided with positioning grooves 311 respectively. The two positioning posts 122 are respectively engaged with the two positioning grooves 311, so that the first circuit board 31 can be clamped between the two positioning posts 122, making the first circuit board 31 more securely installed.

[0073] Please see Figure 4 In some embodiments, the side of the positioning post 122 facing away from the first circuit board 31 is an arc-shaped surface 1221.

[0074] Optionally, the end of the positioning post 122 that engages with the positioning groove 311 has an arc-shaped surface 1221, and the arc-shaped surface 1221 is located on the side of the positioning post 122 facing away from the first circuit board 31, so that the lines connected to the first circuit board 31 can pass through the arc-shaped surface 1221, and the arc-shaped surface 1221 can prevent the positioning post 122 from scratching the lines.

[0075] In some embodiments, the first circuit board 31 and the first radio frequency coil 32 are integrally formed.

[0076] Optionally, the first circuit board 31 can cover the opening of the channel 121, and the first radio frequency coil 32 is located in the middle of the first circuit board 31. The first circuit board 31 and the first radio frequency coil 32 are integrally formed, so that the first circuit board 31 and the first radio frequency coil 32 can be integrated into one unit, which can reduce the space occupied by the first radio frequency component 30 and simplify the structure of the first radio frequency component 30.

[0077] Please see Figure 5 In some embodiments, the ribbon cartridge 20 includes a housing 21, the top of which is provided with a take-up hole 211 and a release hole 212, and both the take-up hole 211 and the release hole 212 are connected to the interior of the housing 21. The second radio frequency component 40 is disposed at the bottom of the housing 21.

[0078] Optionally, a ribbon roll can be disposed inside the housing 21. The ribbon can extend outward from the inside of the housing 21 from the dispensing hole 212 to between the dispensing hole 212 and the take-up hole 211. The ribbon between the dispensing hole 212 and the take-up hole 211 can be used to print labels. After use, the ribbon can extend into the housing 21 through the take-up hole 211 and be wound onto another ribbon roll, so that the ribbon can extend to the top of the housing 21 for printing. After use, the ribbon can also be recycled back into the housing 21. By disposing of the second radio frequency component 40 at the bottom of the housing 21, interference between the second radio frequency component 40 and the ribbon at the top of the housing 21 can be prevented.

[0079] Please see Figure 5 In some embodiments, the ribbon cartridge 20 further includes a dispensing shaft 22 and a take-up shaft 23, which are spaced apart inside the housing 21. The ribbon wound on the dispensing shaft 22 extends out from the dispensing hole 212, and the ribbon outside the housing 21 can extend into the housing 21 from the take-up hole 211 and be wound on the take-up shaft 23.

[0080] Optionally, the housing 21 includes a first housing portion and a second housing portion, the first housing portion being spaced apart from each other, and the first housing portion forming a winding cavity, the second housing portion forming a dispensing cavity, the first housing portion also having a winding hole 211 communicating with the winding cavity, the second housing portion having a dispensing hole 212 communicating with the dispensing cavity, and the winding hole 211 being disposed toward the dispensing hole 212.

[0081] More specifically, both the take-up hole 211 and the dispensing hole 212 are positioned towards the space between the first shell portion and the second shell portion, so that after the ribbon on the dispensing shaft 22 extends out from the dispensing hole 212, it can extend into the take-up cavity through the take-up hole 211, and the ribbon can be wound around the take-up shaft 23. Thus, the ribbon can be dispensed while the ribbon is being printed, and after the ribbon has finished printing, the used ribbon can be easily recycled back to the take-up shaft 23.
