Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an ink cartridge adjustment mechanism of a printer. [Prior Art·] [0002] The ink cartridge of the printer is used to carry ink cartridges. Typically, the print head is placed on the ink cartridge or ink cartridge. The distance between the print head and the print media, such as paper, is one of the important parameters that affect print quality. In the production process of the printer, there is often a certain error in the distance between the print head on the ink cartridge and the printing medium due to errors in processing or assembly. This affects the print quality of the printer. SUMMARY OF THE INVENTION [0003] In view of the above, it is desirable to provide an ink cartridge adjustment mechanism that can adjust the distance between a print head and a print medium. [0004] An ink cartridge adjusting mechanism includes a frame, an ink cartridge mounted to the frame, and an adjusting device. The adjusting device includes a rotating shaft, a cam fixed to the rotating shaft, and a solid a gear disposed on the rotating shaft, the Q rotating shaft is rotatably mounted on the ink cartridge, the gear includes a plurality of teeth, the ink cartridge is provided with a block, and the card is stuck to any two adjacent teeth of the gear Between the cams abuts the frame. [0005] The adjusting device of the ink cartridge adjusting mechanism of the present invention can finely adjust the ink cartridge to achieve the effect of adjusting the distance between the printing head and the printing medium. Embodiments [0006] Referring to FIG. 1, a preferred embodiment of the ink cartridge adjustment mechanism 10 of the present invention includes a frame 20, an ink cartridge holder 40, and an adjustment device 60. 098119598 Form No. A0101 Page 3 of 15 0982033273-0 201043477 [0007] The frame 20 includes a slide rail 21 and a plurality of support bodies [0008] 200 for erecting the slide rails 21. The slide rail 21 is for slidingly mounting the ink cartridge 40. The slide rail 21 includes a vertical back plate 23, a top plate 24 horizontally extending from the top edge of the back plate 23, a bottom plate 26 horizontally extending from the bottom edge of the plate 21 and opposed to the top plate 24, and a bottom plate 24 away from the top plate 24. The upper edge 25 of the back plate 23 extends perpendicularly toward the bottom plate 26 and a lower flange 27 extending perpendicularly from the side edge of the bottom plate 26 away from the back plate 23 toward the top plate 24. 2, the ink cartridge 40 is used to carry an ink cartridge (not shown), and the ink cartridge 40 or the ink cartridge is provided with a print head (not shown). In the present embodiment, the print head is disposed at the front end of the ink cartridge 40. The rear end of the ink cartridge 40 is provided with two sliding portions 41. Each of the sliding portions 41 includes a first clamping block 411 and a second clamping block 412 which are spaced apart from each other. The rear end portion of the ink sill 40 is provided with two load-bearing shaft portions 43 spaced apart from each other. A avoidance groove 45 is formed between the two load shaft portions 43. Each of the carrier shaft portions 43 has two coaxial "C" shaped shaft holes 47. A rear end portion of the ink cartridge 40 extends a card block 49 on the left and right sides of the two load shaft portions 43, respectively. The block 49 < is higher than the shaft hole 47 of the load-bearing portion 43 and protrudes downward. [0009] Referring to Figure 3, the adjustment device 60 includes a cam 61, two rotating shafts 63, and two gears 65. The two rotating shafts 63 are respectively connected to both sides of the cam 61 and coaxial. The two rotating shafts 63 are respectively connected to the ends of the two rotating shafts 63 away from the cam 61. Each gear 65 includes eight teeth 651. A groove 653 is defined in a side of each of the gears 65 remote from the cam 61. [0010] Please continue to refer to FIG. 4 and FIG. 5, during assembly, the adjusting device 098119598 63 is respectively inserted into the shaft hole 47 of the two wheel portions 43 of the ink base 40 so that the protrusion (10) of the adjusting device 60 is located at two materials. Form No. A0101 between the parts 43 Page 4 / Total 15 pages 0992033273-0 201043477 'Each each of the blocks 49 of the ink cartridge 40 is respectively engaged between any two adjacent teeth 651 of the corresponding gear 65 (see Fig. 6) ). The ink cartridge 4 is attached to the slide rail 21 from one end of the slide rail 21 of the frame 20 such that the first clamp block 4U and the second clamp block 412 of each sliding portion 41 of the ink cartridge 40 are sandwiched. Both sides of the lower folded edge 27 of the slide rail 21. At this time, the cam 61 of the adjusting device 6A abuts against the inside of the upper folded edge 25 of the slide rail 21 (see Fig. 6). [0011] Ο 〇 Please, in conjunction with FIG. 6 ''printing medium (not shown), be placed substantially flat below the ink cartridge 4〇. When adjusting the distance between the print head on the ink cartridge 4 and the print medium, a screw driver (not shown) can be inserted into the groove 653 of a gear 65 of the adjustment device 6〇 or by using a pliers (not shown). The sweet gear-gear 65 rotates the cam 61 of the adjustment device 60. Since the cam is rotated against the upper flange 25 of the slide rail 21, the cam 61 is subjected to the reaction force of the upper flange 25, and the reaction force is transmitted to the ink cartridge 40 through the rotating shaft 63 of the adjusting device 60. The sliding portion 41 at the lower flange 27 of the rail 21 produces a weak elastic deformation 'so that the ink cartridge 40 is slightly rotated relative to the lower flange 27 of the rail 21' to fine-tune the print head on the ink holder 40. The destination of the distance between print media. When the cam 61 is rotated to the proper position, each of the blocks 49 of the ink cartridge 40 is respectively caught between a pair of adjacent teeth 651 of the corresponding gear 65 to position the cam 61. In other embodiments, a gear 65 on the adjustment device 60 and a corresponding shaft 63 can be omitted, and a corresponding one of the axle portions 43 and a slider 49 of the ink cartridge 40 can be omitted. At this time, the groove 653 may also be opened on the cam 61. Further, each of the carrier portions 43 may have only one "c" shaped shaft hole 47. [0012] In other embodiments, a sliding portion 41 098119598 on the adjustment device 60 may be omitted. Form No. A0101 Page 5 / Total 15 Page 0992033273-0 201043477 [0013] In other embodiments, each of the adjustment devices 60 The number of teeth 651 of a gear 65 can be increased or decreased to change the number of times the cam 61 can be positioned every revolution, thereby changing the adjustment accuracy of the fine adjustment. [0014] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the present invention are intended to be included within the scope of the following claims.
