Detachable cartridge for dye-sublimation printer{CARTRIDGE FOR THERMAL SUBLIMATION PRINTER}

The present invention relates to a cartridge mounted on a dye-sublimation printer, and more particularly, to a detachable cartridge in which a separate ribbon frame and a cassette are easily and firmly coupled.

In recent years, with the rapid spread of smartphones, many people are taking pictures of events or everyday life.

For this reason, in recent years, portable sublimation printers that can communicate with a portable smartphone by wire/wireless communication and print photos taken with a smartphone with high quality on the fly have been gradually developed and distributed.

As is well known, a dye-sublimation printer refers to a printer in which heat is applied to a thermal transfer ribbon coated with a dye so that the dye on the ribbon is transferred and fixed to a recording medium.

The structure of a conventional dye-sublimation printer will be described with reference to FIGS. 1 to 3.

In the conventional dye-sublimation printer 200, a cartridge insertion hole 211 is formed so that the cartridge 100 is inserted from the side.

The printer 200 includes a printer body 210 having a cartridge insertion hole 211 formed on a side thereof, a side cover 220, and a pressure spring 230.

The printer body 210 has an outlet 212 through which the recording medium is drawn out, a first bushing 213, a second bushing 214 and a cartridge fixing protrusion 215 that are coupled to the cartridge 100.

The cartridge fixing protrusion 215 is a wedge-shaped member protruding from the inner surface of the printer body 210 for a certain length, and is fitted with the cartridge fixing hole 116 of the cartridge 100 inserted into the cartridge insertion hole 211 In combination, the cartridge 100 is guided to be disposed at a predetermined position of the printer 200 and is fixed at the same time, and the cartridge 100 is prevented from being separated from the printer 200.

The side cover 220 is rotatably installed on the side of the printer body 210 so that the cartridge insertion hole 211 is selectively opened and closed.

The pressure spring 230 is a leaf spring installed on the lower surface of the upper housing 210a of the printer body 210, and the upper surface of the recording medium receiving unit 111 of the cartridge 100 accommodated in the printer body 210 It is in close contact and provides an elastic force for pressing the recording medium receiving portion 111.

4 and 5 show a conventional cartridge. The cartridge 100 is a cartridge body integrally formed by arranging a recording medium storage unit 111, a supply reel 120 wound up the ink ribbon, and a winding reel 130 winding the printed ink ribbon in a row. It includes a portion 110, a cartridge cover portion 140, and a pressure spring hole 150.

In addition, the cartridge 100 is provided with a cartridge fixing groove 116 that is fitted with the cartridge fixing protrusion 215 so that the cartridge 100 is fixed to a predetermined position of the printer, and inserted into the printer 200 Prevents the cartridge 100 from being separated from the printer 200.

In addition, a handle 117 for gripping the cartridge 100 is installed so that the user can grip it when removing the cartridge 100 inserted in the printer 200 so that it can be easily removed from the printer 200.

In the conventional cartridge configured as described above, since the recording medium storage unit 111 is integrally formed with the cartridge body unit 110 on which the ribbon is mounted, it is not easy to transfer and store the cartridge.

In particular, when there is a defect in either the recording medium receiving unit 111 or the portion for mounting the ribbon, there is a problem that the entire cartridge needs to be replaced.

In addition, when the ribbon supplied from the supply reel is wound on the take-up reel, the ribbon is often twisted or wrinkled during the transfer path.

In addition, a certain inspection process goes through the production process of the printer. For example, after mounting the cartridge 100 to the printer 200, an image is printed to test the operation or image quality of the printer 200. However, in the conventional printer 200, when mounting the cartridge 100 to the printer, as described above, the cartridge fixing groove 116 is fitted and fixed with the fixing protrusion 215 formed in the housing 210A of the printer. . Therefore, in order to proceed with the above test, the test can be performed only in the state that the housing 210a is completely assembled to the printer body 210, and there is a problem that the completely assembled product must be discarded according to the test result.

Hereinafter, the structure and operation of the cartridge according to the present invention will be described in detail with reference to the accompanying drawings.

6 is a perspective view showing a combined state of the detachable cartridge 1 according to the present invention, and FIGS. 7 and 8 are exploded perspective views, and the embodiment 1 according to the present invention is a ribbon frame 120 and a cassette 10 Is formed separately, and is used by combining them.

The ribbon frame 20 and the cassette 10 will be described in detail with reference to FIGS. 6 to 8.

The ribbon frame 20 is provided with a supply reel mounting portion 21 so that a supply reel of the ribbon can be mounted, and a winding reel mounting portion 22 is formed so that the winding reel can be mounted.

In addition, the cassette 10 is a component in which a plurality of recording media (not shown) such as print paper are stacked in the vertical direction.

In particular, the cassette 10 has fixing blocks 30 protruding outwardly on both side walls, and the fixing blocks 30 are inserted and fixed to both side walls of the ribbon frame 20. Are formed respectively.

9 shows the fixing block 30 of the cassette 10 according to the present invention. As shown, the fixing block 30 is formed in a substantially rectangular parallelepiped shape protruding outward from both side walls of the cassette 10.

In addition, binding hooks 31 are formed in the fixing block 30, specifically, both side walls 32 of the fixing block 30 are formed vertically, and the binding hooks 31 are formed in the both side walls 32 ) Is provided between. In addition, since the binding hook 31 needs to be retracted elastically to be mounted in the binding hole 44, slits 30a are formed on both sides of the binding hook 31, respectively. That is, the slit 30a is formed between the both side walls 32 and the binding hook 31 of the fixed block 30.

In addition, in order for the binding hook 31 to retreat elastically, a space for retreating to the rear side should be secured in addition to the slits 30a formed on both sides. That is, an escape groove (refer to '30b' in FIG. 8) is formed between the side wall 32 of the cassette 10 and the binding hook 31.

In addition, the binding hook 31 is formed to protrude to the outside of the fixing block 30, in particular, has an inclined surface (31a) downward downward.

Figure 10 shows the coupling portion 40 formed in the ribbon frame according to the present invention.

As shown, coupling portions 40 are formed on both side walls of the ribbon frame 20, and the coupling portion 40 has a rectangular seating surface 41 formed on an inner surface thereof. That is, a part of the fixing block 30 is mounted on the seating surface 41 and is coupled.

In this way, a binding hook 31 and a binding hole 44 are formed so that a part of the fixing block 30 is firmly seated on the seating surface 41. The shape is fitted so that a part of the fixing block 30 is seated on the seating surface 41.

In addition, a pair of guides 42 opposed to each other with the binding hole 44 interposed therebetween are formed to protrude inward, and the guide 42 guides the movement of both side walls 32 of the fixing block 30 It is a component that guides the insertion. That is, the fixing block 30 moves along the guide 42 so that the binding hook 31 is mounted in the binding hole 44.

The pair of guides 42 serves to guide the movement of the fixed block 30 and at the same time prevent the left and right flow in a state in which the fixed block 30 is coupled to the coupling part 40. If the fixed block 30 is fixed to the coupling part 40 and flows to the left and right, the cassette 10 and the ribbon frame 20 are not mounted horizontally and are tilted so that the transfer of the recording medium is not smooth. As a result, the print quality is deteriorated.

Therefore, the facing surface of the pair of guides 42 must be in close contact with the side wall 32 of the fixed block 30, and for this purpose, the separation distance between the pair of guides 42 is the width of the fixed block 30 Is the same as

In addition, a stopper 43 is connected to the upper end of the pair of guides 42 in the horizontal direction. That is, the stopper 43 is formed to protrude inward from the coupling portion 40. The stopper 43 is a configuration for preventing the vertical flow of the fixed block 30, which will be described later in detail.

On the other hand, the coupling portion 40 is formed with'c'-shaped sidewalls whose lower portion is opened by a pair of guides 42 and a stopper 43, and thus, a rectangular seating surface on the coupling portion 40 (41) is formed. In addition, the fixing block 30 is mounted on the mounting surface 41, and the binding hook 31 is mounted and fixed in the binding hole 44. The both side walls 32 of the fixing block 30 formed vertically in this way are in close contact with the pair of guides 42 formed vertically, respectively, and the upper end of the fixing block 30 formed horizontally is a stopper 43 formed horizontally. Will be in close contact with. Therefore, since the side wall 32 and the guide 42 of the fixed block, the top of the fixed block and the surface such as the stopper 43 meet and are in close contact, the fixed block 30 is very stably fixed without flow in the vertical and horizontal directions. It becomes a structure.

A process of combining the separately formed ribbon frame 20 and the cassette 10 will be described with reference to FIG. 11.

As described above, plate-shaped coupling portions 40 are formed on both side walls of the ribbon frame 20, and a pair of guides 42 and a stopper 43 are formed on the inner side of the coupling portion 40. ), the seating surface 41 is formed.

On the other hand, the cassette 10 is positioned under the ribbon frame 20, the cassette 10 is lifted (moved), and the fixing blocks 30 protruding on both side walls thereof are introduced between the pair of guides. .

In this case, both side walls of the fixing block 30 are guided and inserted by the guide 42. When the fixed block 30 ascends in this way, the inclined surface 31a formed on the binding hook 31 comes into contact with the lower surface 46 of the coupling portion 40. In this state, when the fixing block 30 is further raised, the binding hook 31 is retracted to the rear side (see Fig. 11 (a)). This is because the escape groove 30b is formed between the side wall of the cassette 10 and the binding hook 31. In addition, the coupling portion 40 may be displaced (retracted) to the opposite side, but to prevent this, a rib (see '45' in FIG. 13) is formed between the sidewall of the ribbon frame 10 and the coupling portion 40 have. The side wall of the ribbon frame 20, specifically, the bottom surface of the supply reel mounting portion 21 of the ribbon frame 20 is extended so that the coupling portion is orthogonal, and the rib 45 is formed to have an inclined surface on such an orthogonal surface. . The ribs 45 are formed on upper ends of both ends of the binding hole 44, respectively.

In other words, when the inclined surface 31a of the binding hook 31 rises while in contact with the lower end of the coupling portion 40, the coupling portion 40 is not displaced (retracted) and the binding hook 31 ) Is elastically displaced (deformed) and bound.

When further rising in this state, the binding hook 31 retracted as the binding hook 31 meets the binding hole 44 is restored to its original state and is mounted in the binding hole 44 (Fig. 11 (b)). Reference).

Referring to FIG. 12, a space (S) between the bottom surface of the ribbon frame 20 and the top surface of the cassette 10 in a state in which the binding hook 31 is inserted and mounted at the lower end of the binding hole 44 Is formed. Accordingly, even when the binding hook 31 is inserted and mounted at the lower end of the binding hole 44, the fixing block 30 may be further raised. In this way, if the binding hook 31 is additionally raised while being inserted into the binding hole 44, a problem such as shaking of the recording medium during printing occurs. Therefore, in this embodiment, after the binding hook 31 is inserted into the lower end of the binding hole 44 and the cassette 10 is coupled to the ribbon frame 20, the fixing block 30 is prevented from further rising. A stopper 43 is provided so as to be. As described above, the stopper 43 is formed to protrude inward to connect the upper ends of the pair of guides 42. The stopper 43 is positioned in the space S between the bottom surface of the ribbon frame 20 and the top surface of the cassette 10. Accordingly, when the binding hook 31 is inserted and fixed at the lower end of the binding hole 44, the fixing block 30 is additionally raised to prevent the cassette 10 from flowing in the vertical direction.
