Wherein, control in this application is the negative direction of first direction and the positive direction of first direction respectively.

Preferably, in an embodiment of the present invention, the first direction, the second direction and the third direction are orthogonal to each other.

The structure and function of the solution of the present application will now be described in detail with reference to fig. 1 to 7.

The first embodiment:

an implementation of the present invention provides a print cartridge 1 that can be used to load and secure a print tape assembly 2. Referring to fig. 2 and 3, the box 1 includes a frame 11. Frame 11 has a feed channel, U-shaped section 111 and a U-shaped slot 112. The U-shaped groove 111 has a first opening facing the negative side of the second direction, and the U-shaped groove 112 has a second opening facing the positive side of the second direction. U-shaped channel 112 has a hold-down device in a second direction, which in this embodiment is hold-down plate 12. The bottom of the U-shaped zone 111 is provided with a tensioning portion 13. The feeding path 3 includes a first path 31 and a second path 32 communicating with the first path 31. The first path 31 is located on the positive direction side of the tension section 13 in the second direction as viewed from the first direction. Wherein the pressing plate 12 is located on the negative direction side of the tension part 13 in the second direction as viewed from the first direction. The print cartridge 1 of the present embodiment further includes a print tape storage 113 and a print tape recovery 114, wherein one end of the print tape 21 is fixed and wound around the storage roll 22, and the storage roll 22 is installed in the print tape storage 113 to fix one end of the print tape 21. The other end of the print tape 21 is fixed and wound on the recovery roll 23, and the recovery roll 23 is installed in the print tape recovery bin 114 to fix the other end of the print tape 21. The ends of the print ribbon 21 are fixed to the storage roll 22 and the recovery roll 23, respectively, so that portions thereof can be disposed in the first path 31 and the second path 32.

In the present embodiment, the pressure strip 12 is inserted into the frame 11 from the positive direction side of the frame 11 in the second direction, and when the pressure strip 12 is fixed to the frame 11, the above-described second path 32 is formed on the frame 11, wherein the second path 32 is located on the negative direction side of the pressure strip 12 in the second direction. Referring to fig. 1, it can be seen that in the prior art, where the platen 12 is integrally formed with the frame 11, the print ribbon 21 needs to be free at least one end thereof from the shaft and pass the free end through the reversing hole so that the print ribbon can be positioned partially on the first path and partially on the second path when the print ribbon assembly 2 is loaded. The platen 12 of the present embodiment can be attached to the frame 11 from the forward direction side of the frame 11 after at least part of the print tape 21 is attached to the frame 11, and defines part of the print tape 21 on the second path 32 so that the print tape 21 can be fed along the second path 32. And the print tape 21 can be fed along the feed path 3 by being supported on the tension 13 and the pressure plate 12. The above-described structure, in conjunction with fig. 1, enables the printing tape assembly 2 to be mounted more easily without having to pass the printing tape 21 through the reversing hole S1' and then fix the printing tape 21 on a shaft. Meanwhile, the problem that the printing tape 21 is skewed in the third direction due to installation errors in the process of firstly enabling the printing tape 21 to pass through the reversing hole S1' and then fixing the printing tape 21 with the shaft can be solved.

Preferably, the pressing plate 12 is made of a metal material, for example, a metal plate material formed by stamping and machining, or integrally formed by alloy casting. It is understood that in other embodiments, the compression plate 12 can be integrally molded from a resin material.

Second embodiment:

based on the first embodiment, in the second embodiment, with reference to fig. 4, the pressing plate 12 includes a base plate 51, and guide portions 52 located at both end portions of the base plate 51 in the first direction. Referring to fig. 5, the guide portion 52 extends in the positive direction side of the second direction. The substrate 51 has the second path 32 on the negative direction side in the second direction. A guide portion 52 between the first path 31 and the second path 32 is formed with a third path 33 for communicating the first path 31 and the second path 32 on a side away from the other guide portion 52. Wherein, the base plate 51 is connected with the guide part 52 in an arc transition way. It will be appreciated that the guide 52 can act as a barrier to space the U-shaped channel 112 from the print ribbon assembly 2.

In the second embodiment, referring to fig. 5, the bottom of the pressing plate (i.e., the side of the base plate 51 on the third path 33) is provided with a bump 511, the bump 511 is close to the side of the storage bin, the bump 511 is gradually inclined and protruded from left to right, specifically, the bump 511 is protruded toward the side of the third path 33, so that the print tape 21 is tensioned and supported on the bump 511 and the tension part 13. The projection 511 is a contact portion 511A of an arc-shaped structure at the intersection of the second path 32 and the third path 33, so that the print tape 21 can be supported on the tension portion 13 and the contact portion 511A and be slidably fitted with the contact portion 511A. The projection 511, which is inclined and raised gradually from left to right, causes the print tape 21 to come into contact with the tension portion 13 of the pressing plate 12, enter the second path 32 without hindrance, and then wind around the recovery roller 23 in the extending direction, and tension part of the print tape 21 in the second path 32 by the recovery roller 23 and the tension portion 13. The bumps 511 gradually inclined from left to right reduce the contact area of the print tape 21 with the pressing plate 12 to reduce the friction resistance. The contact portion 511A formed in an arc structure is used to guide the printing tape 21 and achieve the technical effects that the printing tape 21 is not scratched, or a heat-resistant coating or a thermal transfer ink on the surface of the printing tape 21 is not scraped.

It can be understood that the rectangular hollow 14 is used for transferring images during printing, so that a large space is required in the feeding path of the printing tape 21, and the bottom of the U-shaped region 111 is designed to be rectangular hollow for thermal transfer and reduction of the contact area of the printing tape 21 with the frame 11. In the first direction, the rectangular cutouts 14 in the U-shaped region 111 have tensioning ends at both ends, and the two tensioning ends form the tensioning portions 13. The positions of the two tension parts 13 contacting the printing tape 21 are formed into an arc structure along the feeding path of the printing tape 21 for guiding and sliding the printing tape 21, and the technical effects that the printing tape 21 is not scratched, or the heat-resistant coating or the thermal transfer ink on the surface layer of the printing tape 21 is not scraped off are achieved. It is understood that in the present embodiment, the two tension portions 13 are formed on the frame 11, that is, the frame 11 is integrally formed with the two tension portions 13.
