The outer surface of the round shaft body 111 is provided with an elastic structure 112, and The elastic structure 112 is used to press against the media to be printed; of course, in different embodiments, the round shaft body 111 may not have the elastic structure 112.

Please refer to FIGS. 12 to 14 together. FIG. 12 is a schematic diagram of the upper cover mechanism and the base mechanism of the new type printer; FIG. 13 is the interconnection of the printing head kit of the new printer and the pressing roller of the base mechanism. 14 is a schematic view of the connection between the printing head kit of the new type printing machine and the pressing roller of the base mechanism.

As shown in FIG. 12, when the upper cover mechanism 2 is operated away from the base mechanism 1, a part of the print head kit 21 provided on the upper cover mechanism 2 corresponds to the limit groove A exposed on the upper cover body 20, especially the fixing frame 211 It is exposed on the side of the upper cover mechanism 2.

As shown in FIG. 1 to FIG. 3 and FIG. 13, FIG. 13 shows a schematic diagram of the connection relationship between the printing head kit 21 and the pressing roller 11 in the state of FIG. 1. When the upper cover mechanism 2 is placed on the base mechanism 1, the two ends of the pressing roller 11 will be correspondingly located in the two limiting grooves A, and the print head module 212 will be correspondingly located above the pressing roller 11 and waiting to be printed The medium P is correspondingly located between the print head module 212 and the pressing roller 11, and the partial section of the medium P to be printed corresponds to the abutting section 2131 of the print head protective cover 213.

As shown in FIG. 13, a part of the pressing roller 11 is correspondingly accommodated in the limiting groove A, and the limiting groove A will be used to limit the movable range of the fixing frame 211 relative to the pressing roller 11; The pressing roller 11 in the groove A will push against the elastic pressing member 214, and the elastic pressing member 214 will generate an elastic restoring force accordingly; through the elastic restoring force generated by the elastic pressing member 214, the fixing frame 211 will be able to It is more firmly connected to the pressing roller 11 so that when the medium P to be printed moves between the print head module 212 and the pressing roller 11, the fixing frame 211 will not easily move relative to the pressing roller 11, thereby The print head module 212 can print the predetermined pattern on the medium P to be printed more stably.

As shown in FIG. 13, each of the limiting grooves A divides the side plate 2112 into a front end 2112A and a rear end 2112B, and the printhead kit 21 of the printer 100 prints a predetermined pattern on the medium P to be printed. The printing medium P moves from the rear end 2112B to the front end 2112A. In this embodiment, the elastic pressing member 214 is fixedly disposed on the rear end 2112B of the side plate 2112 as an example, but the elastic pressing member 214 is not limited to only being disposed on the rear end 2112B. In different embodiments The elastic pressing member 214 may also be disposed at the front end portion 2112A, but no matter where the elastic pressing member 214 is disposed at the side plate 2112, a part of the elastic pressing member 214 is located in the limiting groove A.

As shown in FIG. 13, it is particularly noted that in practical applications, the applicant has repeatedly and repeatedly tested to find that when the fixing bracket 211 is not provided with an elastic pressing member 214, although the front end 2112A and the rear end The part 2112B has limited the movable range of the fixing frame 211 relative to the pressing roller 11, but during the process of the media P to be printed moving forward and backward, the fixing frame 211 may still be driven by the media P to be printed, while being relative to the pressing roller 11 Move. Therefore, the applicant has discovered after continuous trial and error that the elastic pressing member 214 is provided on the fixing frame 211, the front end portion 2112A, the rear end portion 2112B and the elastic pressing member 214 can jointly limit the fixing frame 211 relative to the pressing roller The range of motion of 11, thus, can greatly improve the problem that the medium P to be printed drives the fixing frame 211 to move.

It is particularly emphasized that the above-mentioned printing head kit 21 can be manufactured and sold independently, and the printing head kit 21 is not limited to being able to be manufactured and sold as one printer 100 together with the upper cover body 20 and the base mechanism 1 . In addition, the fixing frame 211 and the elastic pressing member 214 may also be manufactured and sold as a printing head fixing assembly.

In summary, the design of the new printer, the printing head kit and the printing head fixing assembly can greatly improve the fixing frame to be easily driven by the media to be printed, which makes it fixed to the fixing frame. The problem of the print head module leaving the original predetermined position can improve the printing quality of the printer.

The above is only the preferred and feasible embodiment of the new model, and does not limit the patent scope of the new model. Therefore, all equivalent technical changes made by using the description and drawings of the new model are included in the protection scope of the new model. .
