A handheld printer 10, as shown in Figs. 1 and 2, has a housing 11 as the main part, behind which a handle

connected, wherein a pressure roller set 20 consisting of three vertically arranged pressure rollers 21, 22, 23 is attached to the housing 11, above which an ink roller set 30 consisting of a plurality of ink rollers is arranged, and wherein the rear upper end of the housing 11 is provided with an adhesive tape roller 40, under which a transfer roller 41 and a press roller 43 are provided, wherein the press roller 43 is located under the pressure roller 23 and works in cooperation therewith, and wherein the lowest pressure roller 23 is provided at the front and rear with an ink distribution roller 50 and an adhesive tape press roller 42, and wherein a cutting knife 60 is arranged at the front lower end of the housing 11.

The number of rollers of the aforementioned printing roller set 20 depends on the length of the housing 11, preferably three or four. The ink roller set 30 consists of at least three ink rollers 31 to 33, which are V-shaped. The lowest ink roller 32 works in cooperation with the printing roller 21, and the three ink rollers 32 are each pressed at the top against a spring 34, which is covered by an upper cover 35 located on the top of the housing 11. The ink rubbing roller 50 is a cloth roller and serves to rub away the ink after it touches the lowest printing roller 23. The cutting knife 60 can be a sharp blade or a saw-shaped blade. Alternatively, the pressing roller 43 can be replaced by the metal wire.

The housing 11 has several square holes 111, which are arranged vertically at the same distance and into which the printing rollers 21, 22, 23 can be inserted for fastening, while the housing 11 is provided at the top with several grooves 112 into which the ink rollers 31, 32, 33 can be inserted for fastening. The housing 11 has an axle hole 113 at the rear and upper section, into which

the adhesive tape roller 40 can be inserted for fastening, while the housing 11 has small axle holes 114, 115 at the rear section into which the transfer roller

41 and the press roller 43 can be inserted for fastening. In addition, the housing 11 has an oblique groove 116 and 117 on the front and rear walls, into which the ink distribution roller 50 and the press roller 42 can be inserted for fastening, the housing 11 having a pit 118 in the middle of the front wall, into which an ink fountain 70 (see Fig. 5) can be inserted for fastening. In addition, the lower end of the housing 11 is designed as a curved groove 119 so that the printing process of the lowest printing roller 23 is visible.

On the adhesive tape roller 40, as shown in Fig. 3, an adhesive tape roller 90 is rotatably attached, from which the adhesive tape 91 can be pulled out, which passes through the transfer roller 41, the adhesive tape press roller 42 and the press roller 43 and then glues or closes the opening of objects. The pressure roller 23 and the adhesive tape press roller

42 are in contact with each other, and the adhesive tape 91 is clamped therebetween, so that the adhesive tape pressing roller 42 rotates with the rotation of the pressure roller 23, whereby the adhesive tape 91 can be continuously drawn out from the adhesive tape roll 90. The transfer roller 41 serves to press the adhesive tape 91 so that the adhesive tape 91 can be pulled tight. The rotation of the pressure roller 23 can cause the other pressure rollers 21, 22 to rotate. After the uppermost pressure roller 21 receives the ink from the ink rollers 32, the ink is further printed onto the adhesive tape 91 by the pressure rollers 22, 23. The ink roller set 30 is designed as a V-shaped pit in which the greasy ink 36 (see Fig. 4) is stored. The ink roller set 30 rotates with the rotation of the printing roller set 20, whereby the left and right ink rollers 31, 33 serve to evenly distribute the ink on the printing roller 32.

Preferably, the two lower pressure rollers 22, 23 can be magnetically designed so that the two magnetic rollers can be attracted to each other and thus the rotating ink becomes even smoother and more uniform.

In order to cut off the drawn-out adhesive tape 91 as shown in Fig. 4, it is only necessary to raise the handle 12, whereby the cutting knife 60 arranged at the front lower end comes down so that the adhesive tape can be cut off. In order to facilitate the cutting, the adhesive tape 91 must be pulled tight, which can only be achieved by establishing a tensile force between the pressure roller 23 and the pressing roller 43 on the adhesive tape 91.

The ink supplied by the ink roller set 30 mentioned above is suitable for letterpress printing. Alternatively, the ink may be supplied from the ink fountain 70 as shown in Fig. 5, which is located in the pit 118 on the front wall of the housing. However, this ink is suitable for gravure printing. The ink fountain 70, as shown in Fig. 6, has an ink outlet opening 701 at the bottom for passing the ink onto the printing rollers 22. Since the ink required by gravure printing is thicker, it is preferred that the ink is supplied from the ink fountain 70.

Further, the housing 11 as shown in Fig. 7 differs from the housing 11 shown in Fig. 1 in that the housing 11 shown in Fig. 7 is divided into left and right sections, with the two ends of all the rollers 20, 30, 40, 41, 42, 43, 50 being rotatably disposed between the left and right sections. In order to maintain the balance point, the handle 12 is preferably provided behind the middle part between the two sections of the housing 11. In addition, a curved piece 14 is attached to the upper end of the handle 12,

namely clamped to the rear lower end of the two sections of the housing 11. The three are then fastened by means of screws. The two sections of the housing 11 have a symmetrical oblique groove 13 at the rear upper end into which the adhesive tape roll 40 can be inserted and from which it can be removed in order to facilitate the replacement of the adhesive tape roll 90.

Except for the left and right portions of the casing 11, the difference between the hand printer 10 shown in Figs. 8 and 9 and that shown in Fig. 7 is that a single printing roller 21 and the ink roller set 30 are provided between the left and right portions of the casing 11, while the other printing rollers 21, 22, 23 are respectively mounted inside U-shaped brackets 81 which are fixed at the same distance by means of their respective feet to the rectangular frame 82 which is fixed to the rear end of the casing 11 by means of two axles 86. A plurality of transfer rollers 83 to 85 are rotatably mounted in the rectangular frame 82. The two portions of the casing 11 are provided at the lower end of the front and rear parts with a cross bar 15 and a curved piece 14 so that the front and rear ends of the casing 11 can be kept parallel. Moreover, a cross pin 151 is provided in the middle of the cross bar 15. Further, each axis of the ink roller set 30 is mounted between the two sections of the housing 11 and inserted into the inside of respective grooves 112, so that a top cover 35 and a plurality of springs 34 are to be attached to the upper end of the two sections of the housing 11, respectively.

The U-shaped support 81, as shown in Fig. 10, has a groove 811 to facilitate the insertion or removal of the pressure roller 23, whereby its cleaning or maintenance can also be facilitated. The U-shaped

Carrier 81 has a pulling device at the front which comprises upper and lower cross pins 813, 814 and upper and lower springs 815, while the two cross pins 813, 814 are each hooked to the spiral springs 815 and the other end of the springs is hooked to the cross bar or to the cross pins 151, 813, 814 of the U-shaped carrier 81 (see Fig. 8). By the tension force of several spiral springs 815, the four pressure rollers 21, 22, 23, 24 are contacted with each other at the top and bottom. The U-shaped carrier 81 has an adjustable threaded pin 812 at the front which lies between every two U-shaped carriers 81 so that a suitable distance therebetween can be set.

The lowermost U-shaped support 81, as shown in Fig. 11, has a cutting knife 60 at the bottom front and a pressing roller 87 (or a metal wire) at the back to make close contact with a pressure roller 24.

Fig. 12 shows a disassembly of the printing roller for the mini handheld adhesive tape printer. To remove the printing roller 24 (or other rollers) for cleaning, it is only necessary to disassemble the spiral spring 815 at the front end of the U-shaped support 81, which allows the U-shaped support 81 to rotate backwards about a pivot pin so that the printing roller 24 can be easily removed from the U-shaped support 81 and returned after cleaning. The spiral spring is then hooked back on. The other printing rollers 21, 22, 23 are also disassembled and assembled.

A slight difference between the mini handheld adhesive tape printer shown in Fig. 13 and Fig. 3 is that the handheld printer shown in Fig. 13 uses four printing rollers 21, 22, 23, 24. When the adhesive tape 91 is pulled out from the adhesive tape roll 90, the adhesive tape 91

by the transfer rollers 83, 84, 85. It then passes through the point between the pressure roller 24 and the pressing roller 87 so that the adhesive tape 91 is automatically pulled out while the ink can be applied from the pressure roller 24 to the adhesive tape 91.

Fig. 14 shows an application example of the mini hand printer for adhesive tapes according to the invention according to Fig. 8. The cutting movement is similar to the movement shown in Fig. 4, so that the cutting movement is no longer described here.

Fig. 15 shows another example of using the mini handheld printer for adhesive tapes according to the invention as shown in Fig. 8. When the upper ink roller set 30 is not used, the greasy ink 88 can be filled into the lowermost U-shaped carrier 81 so that the printing roller 24 automatically receives the ink to continue the ink. Preferably, the two lower printing rollers 22, 23 can be magnetically designed so that the two magnetic rollers arranged at the lower end of the housing 11 can be attracted to each other and thus the rotating ink becomes even smoother and more uniform.
