[0046] In related technologies, a printer includes the printer body and printing consumables.

[0047] The printer body includes a housing, a first belt conveyor roller, an impression roller, a print head, a drive motor, and a gear assembly. The first belt conveyor roller, impression roller, print head, drive motor, and gear assembly are all mounted inside the housing. An ink ribbon take-up shaft and a belt conveyor shaft are rotatably mounted inside the housing. The gear assembly includes a first gear, a second gear, and a third gear. The first gear is fixed to the ink ribbon take-up shaft. The second gear is fixed to the belt conveyor shaft. The third gear is located on the first belt conveyor roller. The drive motor drives the first, second, and third gears to rotate.

[0048] The printing consumables include a first core wound with printing tape, a second core wound with adhesive tape, a third core wound with ink tape, a second belt conveyor roller, and an ink tape take-up roller. The second belt conveyor roller is connected to the belt conveyor shaft, and the ink tape take-up roller cooperates with the ink tape take-up shaft. When the drive motor operates, the gear assembly rotates, which drives the second belt conveyor roller, the ink tape take-up roller, and the first belt conveyor roller to rotate synchronously.

[0049] When the printer is working, driven by the drive motor, unused printing tape and ink tape are drawn between the print head and the impression roller, where they are held and thermally transferred. Then, the used ink tape is wound onto the tape take-up roller. Next, the printing tape carrying the printed information is clamped and bonded to the adhesive tape at the first and second tape conveyor rollers, and then discharged from the printer's paper output tray.

[0050] The aforementioned printing consumables have the following disadvantages:

[0051] 1. Since the second conveyor wheel can rotate relative to the housing of the printing consumable, the housing needs to be equipped with a structure for rotating with the second conveyor wheel. The installation of the second conveyor wheel makes the structure of the printing consumable more complicated, affects the assembly efficiency of the printing consumable, and is not conducive to improving the structural strength of the housing of the printing consumable.

[0052] 2. Because the second conveyor wheel rotates, more space needs to be reserved within the printing consumables for its movement, resulting in a relatively large size of the printing consumables, which is not conducive to the miniaturization design of the printer.

[0053] 3. The second conveyor roller of the printing consumables can only be used with printers that have a conveyor shaft, resulting in poor adaptability.

[0054] Based on this, to solve the aforementioned technical problems, this application provides a printing consumable that eliminates the need for a second belt conveyor wheel. Instead, a receiving portion with a receiving surface is provided on the housing of the printing consumable. The receiving surface of the receiving portion, together with the first belt conveyor wheel, provides clamping force to the printing belt and adhesive tape carrying the printing information, causing them to adhere and allowing the finished belt to be conveyed to the outside of the printer by the rotation of the first belt conveyor wheel. This approach improves the structural strength of the housing by utilizing the receiving portion, simplifies the connection structure between the receiving portion and the housing, and increases assembly efficiency. Furthermore, it eliminates the need for reserved movement space within the housing of the printing consumable, reducing its size and facilitating miniaturization of the printer. Additionally, the printer body eliminates the need for a second gear and belt conveyor shaft, reducing power loss during transmission and lowering energy consumption and cost.

[0055] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0056] This application provides a printer. The printer includes, but is not limited to, a thermal printer or a thermal transfer printer.

[0057] The printer according to the embodiments of this application may include: a printer body and printing consumables.

[0058] The printing supplies are detachably mounted on the printer body. This makes it easy to install and remove the printing supplies.

[0059] For example, the detachable connection between printing consumables and the printer body includes, but is not limited to, snap-fit ​​connections.

[0060] The specific structure of the printer body is well known to those skilled in the art and will not be described in detail here.

[0061] The following section provides a detailed description of the structure of the printing consumables in this application.

[0062] Please see Figure 1A , Figure 1B , Figure 1C and Figure 2 , Figure 1A A perspective view of the printing consumable 100 provided in an embodiment of this application; Figure 1BA perspective view of the printing consumable 100 provided in an embodiment of this application; Figure 1C A perspective view of the printing consumable 100 provided in an embodiment of this application; Figure 2 According to Figure 1A An exploded view of the printing consumable 100 shown. According to an embodiment of this application, the printing consumable 100 may include: a housing 1, a first core 3, a second core 2, a third core 4, an ink ribbon recycle wheel 5, and a receiving portion 6.

[0063] The housing 1 includes a first shell portion 11 and a second shell portion 12 that are opposed to each other in a first direction F. For example, in... Figure 1A and Figure 2 In the specific example shown, the first direction F can be the thickness direction of the housing 1. In other embodiments, the first direction F can also be the length direction or the width direction of the housing 1.

[0064] The material of the first shell portion 11 includes, but is not limited to, plastic and metal. The first shell portion 11 includes a first wall panel 111 and a first side panel 112 disposed at the edge of the first wall panel 111 and extending toward the second shell portion 12.

[0065] The material of the second shell portion 12 includes, but is not limited to, plastic and metal. The second shell portion 12 includes a second wall panel 121 and a second side panel 122 disposed at the edge of the second wall panel 121 and extending toward the first shell portion 11. The second wall panel 121 and the first wall panel 111 are disposed opposite to each other in a first direction F.

[0066] It is understood that the structure of the first shell portion 11 and the second shell portion 12 is not limited thereto. In other embodiments, when the first shell portion 11 includes the first side plate 112, the second shell portion 12 may not include the second side plate 122; or, when the second shell portion 12 includes the second side plate 122, the first shell portion 11 may not include the first side plate 112.

[0067] The assembly relationship between the second shell portion 12 and the first shell portion 11 includes, but is not limited to, snap-fit ​​or embedding.

[0068] In this embodiment, by dividing the housing 1 into a first housing part 11 and a second housing part 12, and assembling the first housing part 11 and the second housing part 12, the processing and manufacturing process of the housing 1 can be simplified, and the installation of the first core 3, the second core 2 and the third core 4 inside the housing 1 can be facilitated.

[0069] Please see Figure 3 and Figure 4 , Figure 3 According to Figure 1A The diagram shows a front view of the printing consumable 100 along the first direction F. Figure 4 According to Figure 1A The rear view of the printing consumable 100 along the first direction F is shown. Figure 3 and Figure 4 The printhead 200 is not part of the printing consumables 100, therefore it is drawn with a dashed line. The housing 1 has a mounting hole 19 extending through the housing 1 along a first direction F. The mounting hole 19 extends to the outer peripheral edge of the housing 1 to form a body 13 and a cantilever portion 14 connected to the outer peripheral surface of the body 13. The cantilever portion 14 communicates with the body 13. A mating area 15 is defined between the free end of the cantilever portion 14 and the body 13.

[0070] Specifically, when the printing consumable 100 is installed inside the printer body, the print head 200 can be located inside the mounting hole 19.

[0071] It is understood, of course, that in other embodiments, the housing 1 may not be provided with the mounting hole 19 for accommodating the print head 200; for example, the print head 200 may extend into the housing 1.

[0072] Please continue reading. Figure 2 and combined Figure 5 , Figure 5 According to Figure 1A The diagram shows a partial front view of the printing consumable 100 along a first direction F, wherein the second housing 1 is not shown. The housing 1 has a first outlet 1B and a second outlet 1A.

[0073] The first core 3 is rotatably disposed within the housing 1. Specifically, the first core 3 is rotatably disposed within the body 13. The rotation center line of the first core 3 extends along a first direction F.

[0074] The first core 3 is wound with a first strip 3A. Specifically, in this example, the first strip 3A can be a ribbon, a flat sleeve, or a film. The first outlet 1B is used for the first strip 3A detached from the first core 3 to pass through, that is, the first strip 3A released from the first core 3 can extend to the outside of the housing 1 through the first outlet 1B.

[0075] The second core 2 is rotatably disposed within the housing 1. Specifically, the second core 2 is rotatably disposed within the main body 13. The rotation center line of the second core 2 extends along the first direction F.

[0076] The second core 2 is wound with a second tape 2A. Specifically, in this example, the second tape 2A is an adhesive tape. The second outlet 1A is used for the second tape 2A to pass through after it has detached from the second core 2. That is, the second tape 2A released from the second core 2 can extend out to the outside of the housing 1 through the second outlet 1A.

[0077] The third core 4 is rotatably disposed within the housing 1. Specifically, the third core 4 is rotatably disposed within the body 13. The rotation center line of the third core 4 extends along the first direction F.

[0078] The third core 4 is wound with ink tape 4A. The first outlet 1B can also allow ink tape 4A detached from the third core 4 to pass through. That is, ink tape 4A released from the third core 4 can extend out of the first outlet 1B to the outside of the housing 1. Of course, it is understood that in other embodiments, a third outlet spaced apart from the first outlet 1B can also be provided at the free end of the housing 1, such as the cantilever portion 14 described above, so that ink tape 4A detached from the third core 4 can pass through the third outlet.

[0079] The ribbon take-up roller 5 is rotatably disposed within the housing 1. The rotation center line of the ribbon take-up roller 5 extends along a first direction F. The ribbon take-up roller 5 is used to wind the used ribbon 4A.

[0080] Please continue reading. Figure 2 and Figure 5 The housing 1 also has a recycling inlet 1C. The recycling inlet 1C is used for the ink ribbon 4A after use. That is, the ink ribbon 4A after heat transfer with the first ribbon 3A can enter the housing 1 through the recycling inlet 1C and connect with the ink ribbon recycling wheel 5 so that it can be wound on the ink ribbon recycling wheel 5.

[0081] The rotatable arrangement of the second core 2, the first core 3, the third core 4, and the ink ribbon take-up wheel 5 within the housing 1 is well known to those skilled in the art and will not be described further here.

[0082] The receiving part 6 is disposed on the housing 1. Specifically, the receiving part 6 and the housing 1 are relatively fixed.

[0083] The material of the receiving part 6 includes, but is not limited to, plastic and metal. When the receiving part 6 is plastic, for example, the material of the receiving part 6 is acrylonitrile butadiene styrene plastic (ABS).

[0084] Please see Figure 5 and Figure 6 , Figure 6 According to Figure 2 The diagram shows a perspective view of the receiving portion 6. The receiving portion 6 has a receiving surface 61 exposed outside the housing 1. For example, the receiving surface 61 can be a plane or a curved surface.

[0085] When the printing consumable 100 is installed inside the printer body and the printer is operating, the ink ribbon retraction wheel 5, the impression wheel 400, and the first tape conveyor wheel 300 rotate, and the second tape body 2A, the first tape body 3A, and the ink ribbon 4A are pulled out from the housing 1. The print head 200 engages with the impression wheel 400 at the mating area 15 to provide clamping force on the unused first tape body 3A and ink ribbon 4A extending from the first outlet 1B, thereby achieving thermal transfer between the unused first tape body 3A and ink ribbon 4A, thus forming the first tape body 3A carrying the printing information. Driven by the impression roller 400, the first belt conveyor roller 300, and the ink ribbon recovery shaft, the used ink ribbon 4A enters the housing 1 through the recovery inlet 1C and wraps around the ink ribbon recovery roller 5. Simultaneously, the first belt body 3A and the second belt body 2A, carrying the printed information, move between the first belt conveyor roller 300 and the receiving surface 61 of the receiving part 6. The receiving surface 61 of the receiving part 6 cooperates with the first belt conveyor roller 300 to provide clamping force for the first belt body 3A and the second belt body 2A, causing them to bond together into a finished belt 7. Further driven by the impression roller 400 and the first belt conveyor roller 300, the finished belt 7 can be conveyed to the outside of the printer.

[0086] In this embodiment of the printing consumable 100, a receiving portion 6 with a receiving surface 61 is provided on the housing 1 of the printing consumable 100. The receiving surface 61 of the receiving portion 6 cooperates with the first belt conveyor wheel 300 to provide clamping force for the first belt body 3A and the second belt body 2A carrying printing information, so that the two are bonded together to form a finished belt 7. Furthermore, the finished belt 7 carrying printing information is conveyed to the outside of the printer by the cooperation of the first belt conveyor wheel 300 and the receiving surface 61. In this way, on the one hand, the structural strength of the housing 1 can be improved by using the receiving portion 6, the connection structure between the receiving portion 6 and the housing 1 can be simplified, and the assembly efficiency can be improved; on the other hand, there is no need to reserve movement space in the housing 1, which is conducive to reducing the size of the printing consumable 100 and realizing the miniaturization design of the printer.

[0087] In some embodiments of this application, the coefficient of friction of the receiving surface 61 is less than the coefficient of friction of the outer peripheral surface of the first conveyor wheel 300. This makes the surface of the receiving surface 61 smoother, reduces the friction between the receiving surface 61 and the finished product belt 7, and avoids the problem of restricted conveying of the finished product belt 7 to the outside of the printer caused by the immobility of the receiving part 6 relative to the housing 1.

[0088] Please continue reading. Figure 5 In some embodiments of this application, the second outlet 1A is disposed on the peripheral sidewall of the body 13. The first outlet 1B is located at the free end of the cantilever portion 14. The mating region 15 may be located between the second outlet 1A and the first outlet 1B, and the receiving portion 6 is located on the side of the second outlet 1A away from the mating region 15.

[0089] This makes it easier to shorten the movement trajectory of the ink tape 4A, the first tape body 3A, and the second tape body 2A, thereby improving the structural compactness of the printing consumable 100.

[0090] Please refer to some embodiments of this application. Figure 5 The body 13 has an opening 131 on its peripheral sidewall. The opening 131 has a first wall surface 1311 and a second wall surface 1312 facing each other. The first wall surface 1311 and the second wall surface 1312 are spaced apart circumferentially from the body 13. The first wall surface 1311 is located away from the second wall surface 1312 from the second outlet 1A. A receiving portion 6 is located at the opening 131 and is disposed close to the first wall surface 1311 relative to the second wall surface 1312. The second outlet 1A is defined between the receiving portion 6 and the second wall surface 1312, and the receiving surface 61 is exposed through the opening 131. This results in a simple structure.

[0091] For some specific examples, please refer to Figure 5 and Figure 6 The surface of the receiving part 6 near the second wall surface 1312 is a guiding convex surface 62. The guiding convex surface 62 is in contact with the receiving surface 61. The guiding convex surface 62 is used to guide the second belt 2A to the receiving surface 61. In this way, the reliability of the movement of the second belt 2A can be improved.

[0092] For example, the guiding convex surface 62 can be an arc-shaped surface. This results in a simple structure and facilitates manufacturing. In other embodiments, the guiding convex surface 62 can also be an elliptical arc surface.

[0093] For example, the guiding convex surface 62 is tangent to the receiving surface 61. As a result, the contact between the guiding convex surface 62 and the receiving surface 61 is smooth, which can avoid the problem of rubbing against the second belt 2A and facilitate the smooth movement of the second belt 2A.

[0094] Please continue reading. Figure 5 A guide post 1E is provided on the inner surface of the first wall panel 111 or the second wall panel 121. The guide post 1E is located on the side of the guiding convex surface 62 near the second wall surface 1312, and on the side of the receiving portion 6 opposite to the receiving surface 61. The second belt body 2A extends towards the guiding convex surface 62 after passing around the side of the guide post 1E away from the guiding convex surface 62. In this way, the arrangement of the guide post 1E can help reduce the contact area between the second belt body 2A and the guiding convex surface 62, thereby reducing the friction between them and improving the reliability of the movement of the second belt body 2A.

[0095] In some embodiments of this application, please refer to Figure 7 and Figure 8 , Figure 7 According to Figure 3The cross-sectional view of the printing consumable 100 shown at the AA-line; Figure 8 According to Figure 7 The diagram shows an enlarged view of the portion circled at point B. The first wall panel 111 has a first clearance hole 1111 extending through the first wall panel 111 along a first direction F. The shape of the first clearance hole 1111 includes, but is not limited to, a rectangle, a circle, an ellipse, or an irregular shape.

[0096] The receiving portion 6 has a second clearance hole 64 that extends through the receiving portion 6 along a first direction F. The shape of the second clearance hole 64 includes, but is not limited to, a rectangle, a circle, an ellipse, or an irregular shape.

[0097] The second clearance hole 64 and the first clearance hole 1111 are directly opposite each other in the first direction F. When the printing consumable 100 is installed in the printer body, both the first clearance hole 1111 and the second clearance hole 64 are used to avoid the belt drive shaft in the printer body, so that the belt drive shaft can be located within the first clearance hole 1111 and / or the second clearance hole 64. In this way, it can be adapted to printers with belt drive shafts in related technologies, and also to the printer with reduced belt drive shafts in this application. The printer in this application reduces the use of belt drive shafts and their gears, improves the structural compactness of the printer body, reduces the output power loss of the drive motor, improves the adaptability of printing consumables, and facilitates printer iteration.

[0098] It is understandable that, in order to avoid the conveyor shaft, when the conveyor shaft is partially located in the first avoidance hole 1111 and partially located in the second avoidance hole 64, there are gaps between the conveyor shaft and the wall of the first avoidance hole 1111, and between the conveyor shaft and the wall of the second avoidance hole 64.

[0099] For specific examples, please refer to [link / reference]. Figure 8 And combined Figure 6 The receiving part 6 includes: a first sleeve 65, a second sleeve 66, and a connecting rib 67.

[0100] The outer peripheral surface of the first sleeve 65 has a receiving surface 61 and the aforementioned guiding convex surface 62. The second sleeve 66 is located inside the first sleeve 65 and spaced apart from it. The second sleeve 66 forms part of the second clearance hole 64. A connecting rib 67 connects the first sleeve 65 and the second sleeve 66. In this way, separating the first sleeve 65 and the second sleeve 66 and connecting them with the connecting rib 67 not only simplifies the structure but also helps to reduce the amount of material used in the receiving part 6, reduce the overall weight of the printing consumable 100, and reduce transportation and production costs.

[0101] For example, there can be multiple connecting ribs 67. The multiple connecting ribs 67 are spaced apart circumferentially on the second sleeve 66. This improves the connection reliability between the first sleeve 65 and the second sleeve 66. Figure 6 In the specific example shown, there are four connecting ribs 67. In other examples, there may be two, three, five or six connecting ribs 67.

[0102] For example, the first sleeve 65, the second sleeve 66, and the connecting rib 67 can be integrally molded. This helps to improve the structural strength of the receiving part 6, simplify the processing technology of the receiving part 6, and reduce manufacturing costs. In other embodiments, the connection methods between the first sleeve 65 and the connecting rib 67, and between the second sleeve 66 and the connecting rib 67, may include snap-fit, screw connection, or adhesive bonding.

[0103] Please continue reading. Figure 8 The receiving part 6 also includes a guide cylinder 68. The guide cylinder 68 connects the end of the second sleeve 66 near the first clearance hole 1111 and the inner peripheral wall of the first sleeve 65. The area of ​​the inner peripheral surface of the guide cylinder 68 gradually increases in the direction from the first clearance hole 1111 to the second sleeve 66. In this way, the guiding effect of the guide cylinder 68 allows the belt conveyor shaft to extend into the second clearance hole 64.

[0104] The guide tube 68 forms another part of the second clearance hole 64.

[0105] For example, the inner circumferential surface of the guide cylinder 68 is frustum-shaped or prismatic.

[0106] For example, the first sleeve 65, the second sleeve 66, and the guide cylinder 68 can be integrally molded parts. This helps to improve the structural strength of the receiving part 6, simplify the processing technology of the receiving part 6, and reduce manufacturing costs. In other embodiments, the connection between the first sleeve 65 and the guide cylinder 68, and between the second sleeve 66 and the guide cylinder 68, can also be by snap-fit, screw connection, or adhesive bonding.

[0107] It is understood that in other embodiments, the guide cylinder 68 may not be provided in the receiving part 6. In this case, the second clearance hole 64 may be formed by the second sleeve 66. Furthermore, the structure of the receiving part 6 is not limited to this. In other embodiments, the receiving part 6 may only include the first sleeve 65, which defines the second clearance hole 64.

[0108] Based on this, please continue to refer to Figure 8 The first sleeve 65 is clamped between the first wall plate 111 and the second wall plate 121. In this way, the clamping force of the first wall plate 111 and the second wall plate 121 can restrict the movement of the receiving part 6 in the first direction F.

[0109] Please continue reading. Figure 8 In some embodiments, a limiting plate 651 is provided on the end face of the first sleeve 65 facing the first wall plate 111. The limiting plate 651 is located inside the first clearance hole 1111 and engages with the wall of the first clearance hole 1111 for limitation. In this way, by utilizing the engagement between the limiting plate 651 and the wall of the first clearance hole 1111, the movement of the receiving part 6 in the direction perpendicular to the first direction F can be limited to a certain extent.

[0110] For example, the limiting plate 651 and the first sleeve 65 can be integrally molded. This helps to improve the connection strength between the limiting plate 651 and the first sleeve 65, simplify the processing technology of both, and reduce manufacturing costs. In other embodiments, the connection between the limiting plate 651 and the first sleeve 65 can also be by snap-fit, screw connection, or adhesive bonding.

[0111] For example, the shape of the limiting plate 651 includes, but is not limited to, a rectangle, a triangle, or an arc extending circumferentially along the first clearance hole 1111.

[0112] Please continue reading. Figure 8 In some embodiments, the second wall panel 121 has a limiting hole 123. The end of the second sleeve 66 away from the first clearance hole 1111 is confined within the limiting hole 123. In this way, by utilizing the limiting engagement between the second sleeve 66 and the second clearance hole 64, the movement of the receiving part 6 in the direction perpendicular to the first direction F can be further restricted.

[0113] For example, the shape and size of the outer periphery of the limiting hole 123 and the second sleeve 66 are the same. This can improve their compatibility. Alternatively, the diameter of the limiting hole 123 is larger than the diameter of the second sleeve 66, which facilitates the installation of the second sleeve 66 with the limiting hole 123. Or, a guide surface (not shown in the figure) is provided at the end of the second sleeve 66 away from 1111, which facilitates the insertion of the second sleeve 66 into the limiting hole 123.

[0114] Please see Figure 9 and Figure 10 , Figure 9 According to Figure 2 A perspective view of the first housing 1 shown; Figure 10 According to Figure 9 The diagram shows an enlarged view of the portion circled at point C in the first housing 1. A first positioning structure 63 is provided on the outer circumferential surface of the first sleeve 65. A second positioning structure 16 is provided on the inner surface of the housing 1. The first positioning structure 63 is one of a groove and a protrusion, and the second positioning structure 16 is the other of a groove and a protrusion. The protrusion fits into the groove. Figure 10In the specific example shown, the first positioning structure 63 is a groove, and the second positioning structure 16 is a protrusion.

[0115] In this way, on the one hand, the cooperation of the first positioning structure 63 and the second positioning structure 16 can play a role in pre-positioning the assembly of the receiving part 6 and the housing 1, thereby improving assembly efficiency; on the other hand, since there is a contact force between the receiving part 6 and the first belt conveyor wheel 300, and since the guiding convex surface 62 plays a guiding role on the second belt body 2A, there is also a certain degree of contact force between the guiding convex surface 62 and the second belt body 2A. The cooperation of the first positioning structure 63 and the second positioning structure 16 can prevent the receiving part 6 from moving in the direction perpendicular to the first direction F due to the contact force.

[0116] Based on this, please continue to refer to Figure 10 The first positioning structure 63 is provided on the side surface of the first sleeve 65 opposite to the guide convex surface. In this way, the movement of the receiving part 6 in the direction perpendicular to the first direction F caused by the abutment force from the second belt 2A can be effectively avoided.

[0117] For example, there can be multiple first positioning structures 63 and multiple second positioning structures 16. The multiple first positioning structures 63 and multiple second positioning structures 16 are matched in a one-to-one correspondence.

[0118] Please continue reading. Figure 10 The inner surfaces of the first wall panel 111 and / or the second wall panel 121 are provided with protrusions 17. It is understood that the location of the protrusions 17 is not limited to this. In other embodiments, the protrusions 17 may also be provided on the first side panel 112 and / or the second side panel 122. As long as the protrusions 17 are provided on the inner surface of the housing 1, it is acceptable.

[0119] The protrusion 17 is located on the side of the receiving portion 6 opposite to the receiving surface 61. The protrusion 17 is used to cooperate with the receiving portion 6 to limit the deformation of the receiving portion 6 towards the side where the protrusion 17 is located. Specifically, the clamping force between the first belt conveyor wheel 300 and the receiving surface 61 will cause the receiving portion 6 to have a tendency to move and deform in a direction away from the first belt conveyor wheel 300. The protrusion 17 can be used to limit the movement and deformation of the printing consumable 100 away from the first belt conveyor wheel 300 during long-term use, thereby improving the reliability of the cooperation between the receiving portion 6 and the first belt conveyor wheel 300.

[0120] The shape of the protrusion 17 includes, but is not limited to, a cube, a cylinder, or an irregular shape.

[0121] Please see Figure 11 , Figure 11 According to Figure 1AThe image shows an enlarged view of the portion of the printing consumable 100 circled at point D. The aforementioned protrusion 17 can be formed by recessing the outer surface of the housing 1 towards the interior of the housing 1. This results in a protrusion 17 on the inner surface of the housing 1 and a recess 18 with a similar shape to the protrusion 17 on the outer surface of the housing 1. This increases the overall structural strength of the housing 1.

[0122] Please return to the reference. Figure 3 The housing 1 has a positioning notch 1D that penetrates the housing 1 along a first direction F. The positioning notch 1D is used to cooperate with a positioning part on the printer body, thereby playing a positioning role in the assembly of the printing consumable 100 and the printer body.

[0123] This application also provides a printing consumable. The difference between the printing consumable in this embodiment and the printing consumable in any of the above embodiments is that: in this embodiment, the printing consumable does not include the second core 2. At this time, the first tape 3A carrying the printing information, formed after the thermal transfer of the ink tape and the first tape body 3A, moves between the receiving part 6 and the first tape conveyor wheel 300, and is held by the two. Under the rotation of the first tape conveyor wheel 300, it continues to be sent out of the printer.
