Example 1

As shown in fig. 1 to 5, the ribbon cartridge for a label printer of the present invention includes a cartridge body 1, the cartridge body 1 is square, and has four corners, that is: a first corner portion 1a located at the right front, a second corner portion 1b located at the right rear, a third corner portion 1c located at the left rear, and a fourth corner portion 1d located at the left front. The box body 1 comprises an upper box body 11 and a lower box body 12, and the upper box body 11 is buckled on the lower box body 12. The printing medium belt 2 is arranged in the box body 1, the printing medium belt 2 comprises a printing medium main belt 21 and a printing medium base belt 22, the printing medium main belt 21 is adhered to the printing medium base belt 22, and the width of the printing medium main belt 21 is smaller than or equal to that of the printing medium base belt 22. Among them, the width of the printing medium main belt 21 may be 6mm, 9mm, 12mm, etc. The same print media base tape 22 may carry print media main tapes 21 of different widths. The printing head in the label printer can transfer the printing information on the carbon ribbon 3 to the printing medium main belt 21 by matching with the printing roller wheel, and the printing medium belt 2 with the printing information, namely the label, is formed.

The front side of the lower case 12 is provided with a front arm portion 13 and a head insertion portion 14 for inserting a print head. Wherein, the front arm portion 13 includes an outer circumferential wall 111 and an inner circumferential wall 112, and a partition wall 113 is provided in the vertical direction between the outer circumferential wall 111 and the inner circumferential wall 112. A first guide passage 114 is formed between the outer peripheral wall 111 and the partition wall 113, and a second guide passage 115 is formed between the partition wall 113 and the inner peripheral wall 112. Namely: the first guide passage 114 is separated from the second guide passage 115 by a partition wall 113. Wherein the first guide path 114 is used to guide the movement of the print media tape 2 towards the print head insertion part 14, namely: the print media tape 2 travels in the first guide path 114. The second guide path 115 is used to guide the carbon ribbon 3 in the cartridge body 1 to move toward the head insertion portion 14, that is: the carbon ribbon 3 travels in the second guide passage 115. The traveling paths of the printing medium tape 2 and the thermal transfer ribbon 3 are separated by a partition wall 113, and the printing medium tape 2 and the thermal transfer ribbon 3 travel independently in the respective paths without interfering with each other.

The print medium tape 2 and the carbon tape 3 overlap at the tape outlet 117 and exit from the tape outlet 117. The upper case 11 is provided with the band limiting part 110 extending toward the lower case 12 at a corresponding position of the first guide passage 114. The tape restricting portion 110 cooperates with the upper wall surface 116 of the lower cassette to restrict lateral movement of the print media tape 22 and, in turn, the print media tape 2. The lower wall surface 118 of the upper box body is matched with the upper wall surface 116 of the lower box body, so that the lateral movement of the carbon ribbon 3 in the second guide channel 115 can be limited, the printing quality is improved, and the ribbon jamming is avoided.

The print head insertion portion 14 is an elongated hole including a print head insertion portion front wall 141 and a print head insertion portion rear wall 142. An exposure area 143 for exposing the print head is provided between the print head insertion portion front wall 141 and the print head insertion portion rear wall 142 near the first corner 1 a. The inner peripheral wall 112 of the front wall 13 constitutes a head insertion portion front wall 141. The print head of the label printer is located within the exposure area 143. After the printing medium belt 2 and the carbon belt 3 pass through the belt outlet 117, the print head and the print roller clamp the printing medium belt 2 and the carbon belt 3 and transfer the printing information on the carbon belt 3 to the printing medium main belt 21, so as to form the printing medium belt 2 with the printing information, i.e. a label. In use, the main print medium tape 21 needs to be peeled off from the print medium base tape 22. The lower case 12 is also provided, at the position of the first corner 1a, with a tape discharge port 16 through which the printing medium tape 2 having the print information is discharged and a tape feed port 15 which guides the printing medium tape 2 to the tape discharge port 16. The printing medium tape 2 with the print information is discharged through the tape feed opening 15 to the tape discharge opening 16. Preferably, a guide post 17 is provided in the lower case 12 at a position near the fourth corner 1d, and the guide post 17 is used to guide the printing medium tape 2 to the first guide path 114.

Example 2

As shown in fig. 6, embodiment 2 differs from embodiment 1 in that: the printing medium belt 2 is a strip-shaped transparent belt, and a viscous medium belt 4 is arranged in the box body 1. The printing head in the label printer can transfer the printing information on the carbon ribbon 3 to the transparent printing medium ribbon 2 by matching with the printing roller to form a label with a perspective effect. The print medium tape 2 coincides with the viscous medium tape 4 at the tape discharge port 16, and the print medium tape 2 sticks to the viscous medium tape 4. In use, the print medium tape 2 with the print information may be peeled off from the adhesive medium tape 4.
