Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a carbon ribbon holder, a carbon ribbon assembly and a printer for improving printing quality. Background Art

[0002] Chinese utility model patent application number 202321376153.7 discloses a ribbon holder, ribbon assembly, and printer. The ribbon holder is located on a support plate on its upper side, which is used to support printing paper. The ribbon holder also includes four plate-shaped frames extending downward from the lower side of the support plate. The four frames are paired together to form a release roll storage area between one pair of frames, and a recycle roll storage area between the other pair of frames. The ribbon roll release shaft is rotatably mounted to the axis of the release roll storage area, and the ribbon roll recycle shaft is rotatably mounted to the axis of the recycle roll storage area.

[0003] The support plate is equipped with a print port extending vertically, located between the release roll and recycle roll compartments. During printing, the ribbon roll is positioned entirely below the support plate; the paper entering the printer's paper feed path is positioned above and supported by the support plate. The ribbon segment and paper extending between the release roll and recycle roll face the print port, where the paper feed roller and print head work together to press the ribbon segment and paper together.

[0004] However, the existing printer has the problem of poor printing color effect. Summary of the Invention

[0005] A first object of the present invention is to provide a carbon ribbon holder that improves printing and coloring effects.

[0006] A second object of the present invention is to provide a carbon ribbon assembly that improves printing and coloring effects.

[0007] A third object of the present invention is to provide a printer that improves printing and coloring effects.

[0008] The carbon ribbon holder provided by the first purpose of the present invention is provided with a release roll position and a recovery roll position; it is also provided with a printing port, which is located between the release roll position and the recovery roll position; it is also provided with a carbon ribbon support structure, which is located downstream of the printing port, and the carbon ribbon passes through the printing port from the release roll position, bypasses the carbon ribbon support structure, and then extends to the recovery roll position.

[0009] It can be seen from the above scheme that the main reason for the poor printing and coloring effect is that the printing paper and the carbon ribbon can only be overlapped in the printing port due to the separation of the support plate, and the printing paper and the carbon ribbon must also be separated at the end of the printing port. During the printing process, the printing paper and the carbon ribbon are pressed together by the print head and the paper feed roller and then separated from each other after a very short time. The ink cannot be more fully adhered to the printing paper within a shorter adhesion time, resulting in poor paper guide and coloring effect. Especially for small and portable printers, the size of the paper feed direction is reduced, resulting in a shortened distance between the release shaft and the recovery shaft of the carbon ribbon roll, and the size of the printing port is also reduced. This further shortens the overlapping time of the printing paper and the carbon ribbon, and the adhesion effect is worse. To this end, the present invention sets a carbon ribbon support structure downstream of the printing port. The carbon ribbon passing through the printing port is not immediately rolled up onto a recycling roll, but is supported by the support side of the carbon ribbon support structure and is in the paper feed channel and remains overlapped with the printing paper until the carbon ribbon completely passes through the carbon ribbon support structure and is then recycled. Under this setting, the distance from the printing pressing point to the separation point of the printing paper and the carbon ribbon is increased, the attachment time is prolonged, and the printing coloring effect is improved.

[0010] A further solution is that the penetrating direction of the print port is a first direction, and the carbon ribbon support structure and the recovery roll position are opposite to each other along the first direction.

[0011] As can be seen from the above, under this setting, the separation point between the printing paper and the carbon ribbon is further back, further extending the attachment time.

[0012] A further solution is that the carbon ribbon support structure includes an end, which is away from the print port; the axis of the release roll position is the first axis, and the axis of the recovery roll position is the second axis; along the line from the first axis to the second axis, the end is away from the first axis relative to the second axis.

[0013] As can be seen from the above, the separation point between the printing paper and the carbon ribbon is closer to the paper outlet, further extending the attachment time.

[0014] A further solution is to provide an arc surface at the end.

[0015] As can be seen from the above, the carbon ribbon bends and extends towards the recovery roll position after passing the end. The carbon ribbon has a larger wrap angle at the end. The arc surface design makes the carbon ribbon recovery and tape running smoother and has a certain flattening effect on the carbon ribbon.

[0016] A further solution is that the carbon ribbon support structure is provided with a support platform for supporting the carbon ribbon.

[0017] As can be seen from the above, under this setting, the carbon ribbon is supported on the support platform downstream of the print port, and the flat carbon ribbon maintains better contact with the printing paper, which is more conducive to delayed separation between the carbon ribbon and the printing paper.

[0018] Another further solution is to provide a blocking structure, which is located downstream of the carbon ribbon support structure, and a ribbon recovery port is formed between the carbon ribbon support structure and the blocking structure; after the carbon ribbon passes through the support side, it extends to the recovery roll position through the ribbon recovery port.

[0019] As can be seen from the above, a blocking structure is provided downstream of the carbon ribbon supporting structure, and the blocking structure restricts the carbon ribbon from downstream to prevent the carbon ribbon from running out of the printer body.

[0020] A further solution is that the blocking structure is configured as a detachable structure.

[0021] As can be seen from the above, further, in order to facilitate the assembly of the carbon ribbon on the carbon ribbon holder and to reduce the obstruction of the blocking structure to the installation of the carbon ribbon, it is better that the blocking structure is set to a detachable structure.

[0022] In a further embodiment, the blocking structure extends between two axial sides of the retraction reel position.

[0023] As can be seen from the above, under this arrangement, the two extended ends of the blocking structure are detachably connected, making the setting and disassembly of the blocking structure easier; and ensuring that the blocking structure has sufficient length to limit the entire carbon ribbon in the width direction.

[0024] The second purpose of the present invention provides a carbon ribbon assembly including a carbon ribbon holder, a carbon ribbon, a release shaft and a recovery shaft, wherein the carbon ribbon is connected between the release shaft and the recovery shaft; the carbon ribbon holder adopts the above-mentioned carbon ribbon holder; the release shaft is arranged at the axis center of the release roll position, and the recovery shaft is arranged at the axis center of the recovery roll position.

[0025] It can be seen from the above scheme that the present invention sets a carbon ribbon support structure downstream of the printing port. The carbon ribbon passing through the printing port is not immediately rolled up onto the recycling roll, but is supported by the support side of the carbon ribbon support structure and is in the paper feed channel and continues to overlap with the printing paper until the carbon ribbon completely passes through the carbon ribbon support structure and is recycled. Under this setting, the distance from the printing pressing point to the separation point of the printing paper and the carbon ribbon is increased, the attachment time is effectively extended, and the printing coloring effect is improved.

[0026] The third object of the present invention is to provide a printer comprising the above-mentioned carbon ribbon assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] First embodiment of a carbon ribbon holder, a carbon ribbon assembly, and a printer The printer of this embodiment is a portable printer. Figures 1 to 5 A unified spatial rectangular coordinate system is established in each of the drawings. In the coordinate system, the x-axis direction represents the length direction of the printer, the paper width direction of the printing paper 7, the width direction of the carbon ribbon 8, the axial direction of the axis of the release roll position 101 and the release shaft 83 (the first axis 81), and the axial direction of the axis of the recovery roll position 102 and the recovery shaft 84 (the second axis 82). The y-axis direction represents the direction of the line connecting the first axis 81 and the second axis 82. The z-axis direction represents the penetrating direction of the print port 100 and the first direction of the present invention. The printer is as follows: Figure 4 In the placement state shown, the x-axis direction and the y-axis direction are both horizontal directions, and the z-axis direction is vertical, that is, up and down directions.

[0038] See also Figure 1 The printer includes a body 9 and a ribbon assembly 1. The body 9 includes a main body 91 and a cover 92. The cover 92 is a flip-up structure. When closed, the cover 92 and the main body 91 are opposite to each other along the z-axis. The main body 91 has a receiving position 99, and the ribbon assembly 1 is disposed in the receiving position 99. When the cover 92 is opened, the receiving position 99 and the ribbon assembly 1 therein are exposed, and the ribbon assembly 1 can now be removed.

[0039] See also Figure 2 and Figure 3 The carbon ribbon assembly 1 includes a carbon ribbon holder 10 , a carbon ribbon 8 , a release shaft 83 , and a recovery shaft 84 . The carbon ribbon holder 10 includes a detachable blocking structure 13 .

[0040] The carbon ribbon holder 10 includes two first frames 19 and two second frames 18. One first frame 19 and one second frame 18 form a pair of frames. The two pairs of frames are arranged along the y-axis direction. The first frame 19 and the second frame 18 in each pair of frames are arranged on opposite sides of the carbon ribbon holder 10 along the x-axis direction. A release roll position 101 is formed between the first frame 19 and the second frame 18 in one pair of frames, and a recovery roll position 102 is formed between the first frame 19 and the second frame 18 in the other pair of frames.

[0041] The release shaft 83 is installed at the first axis 81 of the release roll position 101, and the two shaft portions at both axial ends of the release shaft 83 are rotatably connected to the axis holes of the first frame 19 and the second frame 18 respectively; the recovery shaft 84 is installed at the second axis 82 of the recovery roll position 102, and the two shaft portions at both axial ends of the recovery shaft 84 are rotatably connected to the axis holes of the first frame 19 and the second frame 18 respectively.

[0042] The carbon ribbon 8 is connected between the release shaft 83 and the reel 84. The portion of the carbon ribbon 8 wound on the release shaft 83 is the release roll 801, and the portion of the carbon ribbon 8 wound on the reel 84 is the reel 802. The release roll 801 is located at the release roll position 101, and the reel 802 is located at the reel position 102. It should be noted that as printing proceeds, the diameter of the release roll 801 gradually decreases, while the diameter of the reel 802 gradually increases.

[0043] In order to facilitate the installation of the release shaft 83 and the recovery shaft 84 , a circular shaft hole is provided on the first frame 19 , while a C-shaped shaft hole with a notch is provided on the second frame 18 .

[0044] The ribbon holder 10 further includes a baffle 17 that extends along the x-axis and is connected between the first frame 19 and the second frame 18 corresponding to the ribbon release position 101. The ribbon holder 10 further includes a ribbon support structure 11 that is configured as a wall plate structure. The ribbon support structure 11 extends along the x-axis and is connected between the first frame 19 and the second frame 18 corresponding to the ribbon release position 101.

[0045] A connecting arm 16 extending along the y-axis direction is connected between the two first frames 19 and between the two second frames 18. The two connecting arms 16, the baffle 17 and the carbon ribbon support structure 11 form a printing port 100 that passes through along the z-axis direction. The printing port 100 is located between the release roll position 101 and the recovery roll position 102.

[0046] See also Figure 4 and Figure 5When the ribbon assembly 1 is installed in the housing 99 of the printer, a paper feed path 900 is formed between the upper side of the ribbon holder 10 and the printer body 9, along the paper feed direction. The paper feed path 900 is the location within the printer body 9 where the printing paper 7 roll passes through the printer body 9 during printing. The entrance of the paper feed path 900 is the paper inlet 901, and the exit is the paper outlet 902.

[0047] Continue to see Figure 3 and Figure 4 The carbon ribbon support structure 11 includes a support side 111 facing the paper feed channel 900 and facing away from the recovery roll position 102. The support side 111 is the upward side of the carbon ribbon support structure 11. The support side 111 is provided with a support platform for supporting the carbon ribbon portion 803, and the support platform has a flat support surface.

[0048] The ribbon support structure 11 further includes a starting end 112 close to the printing port 100 and an end 113 away from the printing port 100 along the paper feeding direction. The support platform is located between the starting end 112 and the end 113. The starting end 112 is provided with a guide slope 1121. The guide slope 1121 is a surface facing the paper feeding channel 900. Figure 4 As shown, along the positive direction of the y-axis, the guiding inclined surface 1121 extends gradually away from the reel recovery position 102 , that is, along the positive direction of the y-axis, the guiding inclined surface 1121 extends gradually upward.

[0049] The end 113 is provided with an arc surface 1131, such as Figure 4 In the x-axis projection, the arc surface 1131 is an arc. The guide slope 1121, the surface of the support side 111, and the arc surface 1131 are connected end to end. The arc surface 1131 extends to the underside of the ribbon support structure 11. The underside of the ribbon support structure 11 is the side opposite to the support side 111 and facing the reel reel position 102.

[0050] Furthermore, in this embodiment, the ribbon support structure 11 and the reel position 102 are opposite each other along the z-axis, that is, the ribbon support structure 11 is located directly above the reel position 102. Furthermore, along the line connecting the first axis 81 and the second axis 82 (i.e., the y-axis), the end 113 is farther from the first axis 81 relative to the second axis 82. That is, along the y-axis, the distance from the end 113 to the first axis 81 is greater than the distance from the second axis 82 to the first axis 81. This arrangement places the end 113 further away from the print port 100.

[0051] Continue to see Figure 3 and Figure 4, buckles 131 are provided at both ends of the length of the blocking structure 13, and buckles 103 are provided near the upper sides of the first frame 19 and the second frame 18 corresponding to the reel recovery position 102 of the carbon ribbon holder 10. The two buckles 131 of the blocking structure 13 are respectively buckled into the two buckles 103 to achieve detachable installation. Furthermore, the buckle 131 includes a downwardly extending elastic arm and a protrusion protruding along the x-axis at the end of the elastic arm. The lower side of the protrusion is configured as a guiding slope, and the buckle 103 is an upwardly open position for the buckle 131 to be inserted downward. The blocking structure 13 limits and blocks the carbon ribbon portion 803 from the downstream to prevent the carbon ribbon portion 803 from leaking out of the machine body 9 through the paper outlet 902.

[0052] Continue to see Figure 3 and Figure 4 In the paper feeding direction, the blocking structure 13 is located downstream of the ribbon support structure 11, and a ribbon recovery port 130 is formed between the ribbon support structure 11 and the blocking structure 13. The ribbon recovery port 130 is connected between the paper feeding channel 900 and the recovery roll position 102.

[0053] See also Figure 4 In the present invention, the improvement of the ribbon path of the carbon ribbon 8 is mainly achieved through the carbon ribbon support structure 11. The carbon ribbon portion 803 of the carbon ribbon 8 refers to the carbon ribbon portion extending between the release roll 801 and the recovery roll 802. After the carbon ribbon portion 803 is unrolled from the release roll 801, it first passes through the lower side of the baffle 17 (the side of the baffle 17 facing away from the paper feed path 900), then passes through the print port 100 from the lower side, and passes out to the upper side of the print port 100, that is, the carbon ribbon portion 803 passes through the print port 100 from the bottom to the top; then the carbon ribbon portion 803 passes through the support side 111 of the carbon ribbon support structure 11, and the carbon ribbon portion 803 is supported by the support side 111 from the bottom of the carbon ribbon portion 803, combined with the carbon ribbon portion 803. Figure 1 As shown, the carbon ribbon portion 803 is located above the carbon ribbon support structure 11 , wherein the guiding slope 1121 enables the carbon ribbon portion 803 to have a tendency to extend obliquely upward and toward the support side 111 .

[0054] After sequentially passing through the support side 111 and the arcuate surface 1131 of the end section 113, the carbon ribbon portion 803 passes downward through the ribbon recovery port 130 and extends to the recovery reel 802. As the recovery shaft 84 rotates, the pulled carbon ribbon portion 803 remains in contact with the arcuate surface 1131, allowing the recovered carbon ribbon portion 803 to be flattened before being rewound. The phrase "the carbon ribbon portion 803 passes downward through the ribbon recovery port 130" does not mean that the carbon ribbon portion 803 passes through the ribbon recovery port 130 along the z-axis. Rather, it means that the carbon ribbon portion 803 enters the ribbon recovery port 130 from the upper opening and exits from the lower opening.

[0055] See also Figure 5 and Figure 1 A paper feed roller 94 is provided on the lower side of the cover body 92, and a print head 93 is provided on the upper side of the body 91. The paper feed roller 94 and the print head 93 are arranged opposite to each other along the z-axis direction, and the paper feed roller 94 and the print head 93 are respectively located on the upper and lower sides of the print port 100. The printing paper 7 enters from the paper inlet 901, passes through the paper feed channel 900 and exits from the paper outlet 902. The printing paper 7 as a whole is located above the baffle 17, the print port 100 and the carbon ribbon support structure 11. At this time, in the z-axis direction, a part of the printing paper 7 and a part of the carbon ribbon part 803 are located between the paper feed roller 94 and the print head 93, and under the upper and lower abutment and pressing action of the paper feed roller 94 and the print head 93, the printing paper 7 and the carbon ribbon part 803 overlap. The present invention defines the position where the printing paper 7 and the carbon ribbon part 803 overlap under the upper and lower abutment and pressing action of the paper feed roller 94 and the print head 93 as the printing position, and the print head 93 heats and transfers the ink on the carbon ribbon part 803 to the printing paper 7.

[0056] With the special design of the carbon ribbon support structure 11 of the carbon ribbon holder 1 of the present invention, the ribbon path of the carbon ribbon portion 803 is changed compared with the prior art. Mainly, after the printing position, the carbon ribbon portion 803 moves on the paper feed channel 900 for a longer time before returning to the recovery roll 802. Since the printing paper 7 and the carbon ribbon portion 803 overlap for a longer time on the paper feed channel 900, the time point when the printing paper 7 and the carbon ribbon portion 803 separate from each other is delayed, so that the time for a certain attachment point of the printing paper 7 to move from the printing position to the separation position is longer, thereby making the attachment time longer and the attachment effect better.

[0057] For example, combined with Figure 4 and Figure 5 Assume that ink begins to adhere to a specific attachment point on the printing paper 7 at the printing position. As the ribbon portion 803 then travels above the ribbon support structure 11 while remaining within the paper path 900, the attachment point travels at least a distance d1 before returning from the ribbon reel 130 to the reel 802 under the guidance of the arcuate surface 1131 at the end 113. The ribbon portion 803 then separates from the attachment point on the printing paper 7 near the end 113. Distance d1 is the linear distance along the y-axis. In reality, the ribbon portion 803 and the printing paper 7 extend in an oblique and zigzag manner from the printing position to the separation position, resulting in a longer ribbon length, a longer attachment period, and better printing results.

[0058] In particular, for small, portable printers, the reduced size shortens the distance between the release axis and the recycle axis of the ribbon roll, and the size of the print port in the y-axis direction also decreases. This further shortens the time it takes for the printing paper and the ribbon to overlap, resulting in a poorer adhesion effect. To this end, the present invention provides a ribbon support structure 11 downstream of the print port 100. The ribbon 8 that passes through the print port 100 is not immediately reeled onto the recycle reel 802, but is supported by the support platform of the ribbon support structure 11 and maintained in the paper feed channel 900 until the ribbon 803 completely passes through the ribbon support structure 11 and is then recycle. Under this arrangement, the distance from the printing nip point to the separation point between the printing paper and the ribbon is increased, the adhesion time is prolonged, and the printing and coloring effect is improved.

[0059] See also Figure 4 and Figure 5 When the ribbon support structure 11 is installed and the ribbon portion 803 is running along the new ribbon path, the ribbon portion 803 may flow out of the printer through the paper outlet 902, affecting normal printing. To address this issue, a blocking structure 13 is provided downstream of the ribbon support structure 11. The blocking structure 13 restricts the ribbon portion 803 downstream and prevents it from flowing out of the printer.

[0060] In this embodiment, the carbon ribbon holder 10 is integrally formed except for the blocking structure 13 , and the recovery roll 802 can be installed after the blocking structure 13 is removed.

[0061] In other embodiments, the blocking structure may be configured as a non-detachable structure, and the two frames and the connecting arm on one axial side of the carbon ribbon holder may be configured as a detachable structure, which can also ensure that the carbon ribbon can be installed.

[0062] In other embodiments, the ribbon recycle port is configured to accommodate both the release and recycle shafts, and the ribbon holder can be integrally formed. With this configuration, when installing the ribbon, the recycle shaft, which has not yet been wound into a larger recycle roll, can be inserted downward through the ribbon recycle port and then installed at the center of the recycle roll position. When the ribbon is exhausted, the release shaft, which no longer has a release roll or has a smaller release roll remaining, can be inserted upward through the print port and then downward through the ribbon recycle port. At this point, the release and recycle shafts are located on the same side, eliminating the issue of inability to remove the ribbon.

[0063] Second embodiment of a carbon ribbon holder, a carbon ribbon assembly, and a printer See also Figure 6 and compare Figure 4In the first embodiment, the recovery roll 802 rotates counterclockwise, while in this embodiment, the recovery roll 802' rotates clockwise, as seen in congruent axial projections. Because the recovery shafts are independently driven, the recovery roll can rotate counterclockwise or clockwise. Importantly, whether the recovery roll rotates counterclockwise or clockwise, it does not alter the portion of the ribbon path that contributes to the adhesion effect within the paper path of the present invention. This portion of the ribbon path extends from the printer port, through the support side 111, and to the recovery roll position 102.

[0064] Carbon ribbon holder, carbon ribbon assembly and printer third embodiment See also Figure 7 In this embodiment, along the direction of the line connecting the first axis 81 to the second axis 82 (i.e., the y-axis direction), the end 613 of the carbon ribbon support structure is closer to the first axis 81 relative to the second axis 82, that is, in the y-axis direction, the distance from the end 613 to the first axis 81 is smaller than the distance from the second axis 82 to the first axis 81.

[0065] Under this setting, although the distance from the printing position to the separation position is shortened compared to the first embodiment, the separation is still significantly delayed and the attachment time is prolonged compared to the background art.

[0066] Carbon ribbon holder, carbon ribbon assembly and printer fourth embodiment See also Figure 8 In this embodiment, no blocking structure is provided downstream of the carbon ribbon supporting structure 61 .

[0067] Fifth embodiment of a carbon ribbon holder, a carbon ribbon assembly, and a printer See also Figure 9 As shown in the schematic diagram, in this embodiment, the ribbon support structure 62 is not located directly above the recycling roll 602 . In the y-axis direction, the ribbon support structure 62 is closer to the printing position 603 than the recycling roll 62 .

[0068] Compared with the background technology, this embodiment can also delay separation and extend the attachment time.

[0069] Sixth embodiment of a carbon ribbon holder, a carbon ribbon assembly, and a printer See also Figure 10 As shown in the schematic diagram, in this embodiment, in the y-axis direction, the end 633 of the ribbon support structure 63 is further away from the printing position 634 relative to the recovery roll 632. Furthermore, in the y-axis direction, the end 633 is further away from the printing position 634 than when the recovery roll 632 is at its maximum diameter. The maximum diameter of the recovery roll 632 refers to the recovery roll 632 when the system recognizes that the ribbon is exhausted and the recovery level is at its maximum.

[0070] Under this setting, the end 633 is as far away from the printing position 634 as possible, which significantly prolongs the attachment time. Of course, it is best that the end 633 does not exceed the paper outlet of the printer in the y-axis direction.

[0071] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
