The two side plates 2112 are formed by two sides opposite to each other of the top plate 2111 extending away from the wide side surface 21111, and the two side plates 2112 are disposed facing each other.

Each side plate 2112 is formed with two first fixing structures 21121, and each first fixing structure may be, for example, a keyhole. The number of the first fixing structures 21121 of each side plate 2112 is not limited to two. In different embodiments, each side plate 2112 may also have only a single first fixing structure 21121. In addition, the positions of the first fixing structures 21121 of the side plates 2112 formed at the side plates 2112 can be changed according to requirements, and are not limited to those shown in the figures.

The print head module 212 includes a heat dissipation block 2121, a circuit board 2122, and a heating element 2123.

The two opposite fixing ends 2131 of the abutting member 213 are opposite to each other, and the abutting member 213 is detachably fixed through four second fixing structures 2131, four first fixing structures 21121 and four locking members 215 Set on the fixing frame 211, and the four second fixing structures 2131, four first fixing structures 21121 and four locking members 215 can cooperate with each other, so that the abutment member 213 is fixed to the fixing frame 211 in at least two postures . Regarding the number of the first fixing structure 21121, the second fixing structure 2131 and the locking member 215, all can be increased or decreased according to the demand, not limited to four.

As shown in FIGS. 7 to 9, in actual application, each first fixing structure 21121 and each second fixing structure 2131 may be, for example, keyholes, and the inner diameter of each first fixing structure 21121 is larger than that of each second fixing structure The inner diameter of 2131, and the plurality of locking members 215 correspond to screws. When the pushing member 213 is disposed on the fixed frame 211, the plurality of locking holes (first fixing structure 21121) of the fixing frame 211 can be opposite to the plurality of locking holes (second fixing structure 2131) of the pushing member 213 The plurality of screws can be locked in the plurality of locking holes provided at the opposite positions, so that the abutting member 213 and the fixing frame 211 are fixed to each other.

Since the inner diameter of each first fixing structure 21121 is larger than the inner diameter of each second fixing structure 2131, when the relevant assembly personnel assemble the abutment piece 213 on the fixing frame 211, the assembly personnel may not lock the screws first , But only to connect both the pressing member 213 and the fixing frame 211, at this time, the assembler will be able to make the pressing member 213 move forward or backward relative to the fixing frame 211 toward or away from the printing head module 212 according to requirements The movement, or the assembling person may rotate the pushing member 213 relative to the fixing frame 211, thereby changing the attitude of the pushing member 213 relative to the fixing frame 211. After the assembler adjusts the posture of the abutment piece 213 relative to the fixing frame 211, the assembler will be able to tighten the screws, so that the abutment piece 213 is fixed to the fixing frame 211 in the posture adjusted by the assembler.

As shown in FIG. 7, FIG. 10 and FIG. 11, in order to facilitate the assembly personnel to better adjust the posture of the abutment member 213 relative to the fixing frame 211, the abutment member 213 may further include a limiting structure 2132. In detail, the pressing member 213 may include a body 213A and the limiting structure 2132. The two wide side surfaces of the body 213A opposite to each other are respectively defined as a top surface 213B and a bottom surface 213C. The body 213A protrudes from the top surface 213B to form the limiting structure 2132, and the bottom surface 213C of the body 213A is used to resist and guide The medium to be printed is a carbon ribbon, and at least a part of the bottom surface may be in an arc shape.

As shown in FIGS. 7 and 11, corresponding to the limiting structure 2132 of the abutment member 213, the fixing frame 211 may have a groove 211A. The groove 211A is used to accommodate the limiting structure 2132, and the width W1 of the limiting structure 2132 is smaller than the width W2 of the groove 211A. When the plurality of locking members 215 do not completely fix the abutting member 213 and the fixing frame 211 to each other, the limiting structure 2132 is correspondingly disposed in the groove 211A, and the limiting structure 2132 can move in the groove 211A and limit the position The structure 2132 and the groove 211A can limit the movement range of the abutting member 213 relative to the fixing frame 211 in a direction away from or close to the print head module 212.

As shown in FIG. 12, in practical applications, due to various factors such as manufacturing and assembly tolerances, when the circuit board 2122 is fixed to the heat dissipation block 2121, a narrow side 2122A of the circuit board 2122 will not be narrower than the heat dissipation block 2121. The side surface 2121A is flush, and the narrow side surface 2122A of the circuit board 2122 and the bottom surface 21212 of the heat dissipation block will form a gap C together.

As shown in FIGS. 10 to 12, a narrow side 213D of the body 213A of the abutment member 213 may also protrude to form a protruding structure 2133, and the opposite sides of the narrow side 213D are respectively opposite to the top surface 213B and the bottom surface 213C connection. As shown in FIG. 11, when the abutment member 213 is fixed to the locking member 215, the narrow side 213D is disposed on the side facing the heat dissipation block 2121, and at least a part of the protruding structure 2133 is correspondingly located in the gap C, thereby protruding The structure 2133 can greatly reduce the gap between the abutment member 213 and the print head module 212, so that the printer 100 can have better printing quality.

More specifically, in the process of printing the predetermined pattern on the medium to be printed by the printer 100, the medium to be printed is moved by the print head module 212 in the direction of the abutting member 213 to leave the printer 100. Generally speaking, before printing a predetermined pattern on the media to be printed, the printer 100 usually moves the media to be printed forward and backward to perform calibration operations accordingly. When the printer 100 performs the calibration operation, if the size of the gap C is relatively large, the leading edge of the media to be printed may fall into the gap C, and if the leading edge of the media to be printed falls into the gap C, then It may cause the media to be printed to be squeezed, and the paper jam may not print, and even if the media to be printed falls into the gap C and then is driven to move out of the gap C, the media to be printed may still deviate from the original preset , The printer 100 does not correctly print the predetermined pattern at the predetermined position of the media to be printed. To put it simply, when the size of the gap C is relatively large, the printer 100 is prone to many unexpected problems, ranging from affecting print quality to being unable to print due to paper jams.

Therefore, according to the design of the protruding structure 2133 of the abutment member 213 of the present embodiment, the user can adjust the position of the abutment member 213 relative to the fixing frame 211 when installing the abutment member 213, thereby utilizing the convexity The structure 2133 is used to fill at least a part of the gap C, and accordingly, the above-mentioned various unexpected problems can occur when the printer 100 performs the calibration operation on the printing medium.

It is particularly emphasized that in the embodiment where the pressing member 213 does not have the protruding structure 2133, the assembler can still adjust the posture of the pressing member 213 so that the pressing member 213 is arranged close to the printing head module 212. It is possible to avoid an additional gap between the pressing member 213 and the print head module 212 in addition to the gap C, thereby also greatly reducing the probability that the leading edge of the medium to be printed falls into the gap C and unexpected problems occur.

As shown in FIGS. 6, 7 and 13, the print head protection cover 214 may be pivotally fixed to the fixing frame 211, and when the print head protection cover 214 is fixed to the fixing frame 211, the print head protection cover 214 may have Rotation relative to the fixed frame 211 is limited. One side of the print head protective cover 214 may have a pressing section 2141 and two guiding sections 2142, the pressing section 2141 is located between the two guiding sections 2142, and the two guiding sections 2142 It may be an inclined plane, and the abutting section 2141 may be a circular arc section. As shown in FIG. 13, in the side view of the print head kit 21, the outer edge of the print head protective cover 214 is generally V-shaped opposite to the fixing frame 211, and the pressing section 2141 will be used to press and guide Refer to the media to be printed. In practical applications, it is possible to change the angle of the heading section 2141 and the two guide sections 2142 to change the angle of the media to be printed into the print head module 212; In the embodiment with a carbon ribbon, by changing the appearance of the abutting section 2141 and the two guiding sections 2142, the angle at which the ribbon enters the print head module 212 can also be changed.

Please refer to FIG. 14 and FIG. 15 together. FIG. 14 shows a schematic side view of another embodiment of the upper cover mechanism of the printer of the new type, and FIG. 15 shows another implementation of the upper cover mechanism of the printer of the new type. Example of a partially enlarged schematic. In the embodiment where the ribbon R is provided inside the printer 100, the ribbon R will bypass the printhead kit 21, and when the printer 100 is operating, some heating points in the heating unit of the printhead module 212 will A portion of the ribbon R is heated to transfer the ink on the ribbon to the media to be printed. When the ribbon R bypasses the printhead kit 21, the partial section of the ribbon R will be resisted by the abutment section 2141 of the printhead protection cover 214 and the bottom surface 213C of the abutment member 213, and The angle θ between the ribbon R and the horizontal line is an acute angle. In specific applications, the relevant assembler may adjust the angle of the included angle θ by adjusting the abutment piece 213, so that the printer 100 can better print the predetermined pattern on the media to be printed with different thicknesses , Label paper.

In more detail, when the relevant assembly personnel assemble the abutment member 213 on the fixing frame 211, the assembling personnel may not first lock the screws but only connect the abutment member 213 and the fixing frame 211, At this time, the assembler will be able to rotate the pressing member 213 relative to the fixing frame 211 according to requirements, thereby changing the posture of the pressing member 213 relative to the fixing frame 211, so that the included angle θ can be changed.

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 pressing member 213 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 is detachably installed on the fixing frame through the pressing member, and the assembly personnel are assembling the printing head, the pressing member and the printing head in the process In the middle, it will be possible to reduce the gap between the printing head and the pressing member by adjusting the fixed position of the pressing member, thereby, when the printer performs paper calibration and the media to be printed moves back and forth, the media to be printed The leading edge of will not easily fall into the gap between the print head and the abutment member, which in turn can achieve better printing quality.
