Description

A printing device that can adjust the height between the print head and the printing medium {PRINTING APPARATUS WITH ADJUSTABLE HEIGHT BETWEEN PRINT HEAD AND PRINTING MEDIUM}

This disclosure relates to a printing device, and specifically to a printing device that improves the quality of a printed design by allowing the height between the print head of the ink cartridge and the printing medium to be adjusted according to the material of the printing medium.

The generally known function of a printer is a device that prints desired designs on paper, fabric, etc.

In the past, relatively large printers were placed in office spaces, homes, etc. and used for office purposes, but recently, products for specific purposes that emphasize portability have been required, and miniaturized printers, such as printers for photo printing purposes, have been released. there is.

Recently, hand held printers have become popular. Handheld printers are small and easy to carry, and can print designs not only on relatively flat surfaces such as paper and fabric, but also on surfaces with changes in the surface, such as human skin.

However, in order for a hand-held printer to properly print a design on print media such as paper, fabric, and human skin, a certain distance must be maintained between the print head of the ink cartridge mounted on the hand-held printer and the print medium.

If the gap is too close or there is contact between the print head of the ink cartridge and the printing medium, printing may not work properly and the design may be distorted.

For example, this is not a problem for relatively flat printing media such as paper and fabric, but in the case of soft printing media such as human skin, if the handheld printer is placed in contact with the human skin and moved to print a design, the human skin may be damaged during the movement. Deformation occurs in the skin.

In this case, the gap between the print head of the ink cartridge and the person's skin may be too close or touch, and as a result, the desired design may not be printed.

In addition, there is a printing device that can perform tattoos on the skin along with handheld printing, but the conventional printing device has a relatively complicated structure to separate the gap between the print head of the ink cartridge and the skin.

Accordingly, there is a need for a printing device that changes the gap between the print head of the ink cartridge and the printing medium with a simple structure.

The flange portion 722 may have a bar shape where both ends of the handle portion 721 are connected.

The reinforcing beam 724 may be disposed at positions corresponding to both ends of the handle portion 721 in the flange portion 722. When the user hooks his/her finger on the handle portion 721 and pulls it, force is concentrated on the connection portion between both ends of the handle portion 721 and the flange portion 722. If the user pulls the handle portion 721 by applying excessive force, the handle portion 721 may separate from the flange portion 722 and the removal bar 720 may be damaged. Therefore, in the embodiment of the present disclosure, the rigidity was reinforced by placing a reinforcing beam 724 at the connection between both ends of the handle portion 721 and the flange portion 722, where force is concentrated. Accordingly, excessive Even if force is applied, the removal bar 720 can be prevented from being damaged and its service life can be extended.

The support arm portion 723 may have a bar shape connected to the end of the flange portion 722. The ink cartridge (K) is seated on the upper part of the support arm portion 723 and can support the ink cartridge (K).

In the embodiment of the present disclosure, the support arm portion 723 is respectively connected to both ends of the flange portion 722 and can support both sides of the ink cartridge (K). Accordingly, when the removal bar 720 rises, the support arm portion 723 raises both sides of the ink cartridge (K) together so that the ink cartridge (K) can be raised stably.

Additionally, although not shown in the drawing, the support arm portion 723 may be connected only to one end of the flange portion 722. At this time, one support arm 723 can be raised while supporting one side of the ink cartridge (K). In general, hand-held printers are small, and therefore the ink cartridge (K) mounted on the hand-held printer is small in size, so it can be raised stably even with a single support arm 723.

The removal guide unit 730 may be disposed on the bar seating portion 710 and the removal bar 720, and may guide the lifting and lowering of the removal bar 720.

Specifically, the removal guide unit 730 may include a guide rod 731, a guide hole 732, a stopper block 733, and a stopper groove 734.

The guide rod 731 may be disposed on the side of the support arm portion 723 so as to protrude outward. In the embodiment of the present disclosure, the guide rod 731 may have a cylindrical shape, but is not necessarily limited thereto.

The guide hole 732 may be arranged to be inclined in the vertical direction in the receiving wall portion 713, and the guide rod 731 may be inserted. The guide rod 731 can move along the longitudinal direction of the guide hole 732.

In an embodiment of the present disclosure, the guide hole 732 may be disposed at an angle from the front of the device body 300 to the rear of the device body 300.

According to this structure, when the user places his or her finger on the handle portion 721 and pulls it, the guide rod 731 moves in an inclined direction along the guide hole 732, and the removal bar 720 rises in an inclined direction accordingly. .

At this time, the user simply moves one finger to the handle 721 and pulls it, causing the removal bar 720 to stably rise in an inclined direction, allowing the ink cartridge (K) to be easily removed.

Of course, although not shown in the drawings, the guide hole 732 may be arranged vertically up and down. At this time, when the user holds the handle 721 with two fingers and pulls it in the vertical direction, the guide rod 731 moves in the vertical direction along the guide hole 732 and the removal bar 720 lifts the ink cartridge (K). It will be done.

However, since the structure in which the guide holes 732 are arranged in the vertical direction requires the user to grab the handle part 721 using two fingers and pull it in the vertical direction, the structure in which the above-mentioned guide holes 732 are arranged in the inclined direction User convenience may be reduced compared to . However, since the structure in which the guide hole 732 is arranged vertically also allows the user to lift the ink cartridge (K) and remove it from the receiving frame 320, the purpose of easily removing the ink cartridge (K) is sufficient. It can be achieved.

The stopper block 733 may have a square plate shape and may be disposed at the bottom of the support arm portion 723 while protruding inward.

The stopper groove 734 may be formed concavely in the bar seating surface portion 711, and may be accommodated when the stopper block 733 is lowered.

Specifically, the stopper groove 734 may include a stopper surface portion 734a and a cut portion 734b.

The stopper surface portion 734a may have a flat surface shape and may be seated when the stopper block 733 is lowered.

The cut portion 734b is cut at an angle so that the stopper block 733 can be raised and lowered in an inclined direction and may be connected to the stopper surface portion 734a. This is to prevent interference when the stopper block 733 moves up and down in the inclined direction.

Meanwhile, the lower sliding part 725 may be formed at an angle at the lower end of the flange part 722.

In addition, the upper sliding part 715 may be formed at a position corresponding to the lower sliding part 725 on the bar seating surface part 711 and at an inclination angle corresponding to the lower sliding part 725. This can support the inclined movement of the flange portion 722.

When the user places his or her finger on the handle portion 721 and pulls it, the lower sliding portion 725 formed at the bottom of the flange portion 722 rises on the upper sliding portion 715 formed on the bar seating surface portion 711. This can alleviate shaking and vibration during the lifting process of the removal bar 720, and even when the removal bar 720 is raised, the lower part of the flange part 722 maintains contact with the upper sliding part 715 and is stable. Ensure that it is supported by . Accordingly, the user can easily remove the ink cartridge (K) while the elevated position of the removal bar 720 is fixed.

Hereinafter, the operation method of the removal means 700 according to an embodiment of the present disclosure will be described with reference to FIGS. 13 and 14.

First, referring to FIG. 13, when the ink cartridge K is mounted inside the receiving frame 320 as shown in FIG. 7, the ink cartridge K is seated on the upper part of the removal bar 720. And the removal bar 720 is accommodated inside the bar seating portion 710.

Next, referring to FIG. 14, if the ink cartridge (K) is used up and needs to be replaced, the user hooks his/her finger on the handle portion 721 and pulls it, and the removal bar 720 is moved by the removal guide unit 730. It moves in the direction of the slope and rises.

Accordingly, the ink cartridge (K) seated on the upper part of the removal bar 720 rises together. At this time, the guide rod 731 rises along the inclined direction of the guide hole 732 and guides the movement of the removal bar 720 in the inclined direction.

And since the lower sliding part 725 of the flange part 722 rides up while maintaining contact with the upper sliding part 715 of the bar seating surface part 711, the removal bar 720 remains in contact with the ink cartridge (K) even after rising. ) is stably supported.

Thereafter, when the user holds the ink cartridge (K) with the remaining hand and raises it upward, the ink cartridge (K) is separated from the removal bar 720 and can be removed from the inside of the receiving frame 320.

When the user releases the handle part 721, the removal bar 720 descends again by gravity and is accommodated inside the bar seating part 710. When a user installs a new ink cartridge (K), the replacement is completed by pushing the removal bar 720 into the receiving frame 320 in a lowered state.

In the embodiment of the present disclosure, the removal means 700 allows the user to easily remove the ink cartridge through the above-described configuration and operation method, which can be expected to improve user convenience. In addition, it is possible to prevent injuries to the user's fingers or nails during the process of removing the ink cartridge (K), and to prevent damage caused by dropping the product.

Hereinafter, with reference to FIGS. 28A to 30B, an operation method of the printing device 100 according to an embodiment of the present disclosure to print a design by changing the usage mode according to the material of the printing medium will be described.

If the user needs to adjust the height between the printing medium and the print head (PH) in response to the material of the printing medium, the user can operate the height adjustment module 500 by manipulating the switch means 800.

For example, if the printing medium is a relatively flat material such as paper or fabric whose surface does not change, the user determines that it is necessary to keep the height between the printing medium and the print head (PH) low in order to print the design clearly. can do. This may correspond to the A usage mode described above.

In this case, as shown in FIGS. 28A and 29A, the user can remove the protective cover 400, press the operation button 620, and immediately print the design on the surface of the print medium shown in FIG. 30A.

In the above usage mode, the height between the surface of the printing medium and the print head (PH) is low, so the design can be clearly printed on the surface of printing media such as paper and fabric.

If the initial state is that the indicator unit 820 is exposed to the outside of the indicator hole 861, the lifting block 510 of the height adjustment module 500 is lowered, so the user can use the indicator unit 820 Push it toward the inside of the indicator hole (861).

Accordingly, the body piece 810 of the switch means 800 moves toward the rear of the device body 300, and in this process, the guide beam 523 moves from the upper rib 521c along the inclined rib 521b. After that, it is located on the lower rib 521a and the lifting wall 513 and the lifting block 510 are raised.

The lifting block 510 moves upward (Z) and is accommodated in the module receiving portion 331 of the support frame 330, the height between the print head (PH) and the printing medium is reduced, and the design is clearly displayed on the printing medium. Can be printed.

Also, for example, if the printing medium is a soft material whose surface changes, such as human skin, the user may determine that it is necessary to maintain a large height between the printing medium and the print head (PH) in order to print the design clearly. You can. This is to prevent the print head (PH) from directly touching the surface of the printing medium and printing the design incorrectly, and to keep the distance between the print head (PH) and the surface of the printing medium considering that the surface of the printing medium is pressed and changes. .

In this case, the user removes the protective cover 400 and presses the button portion 830 toward the inside of the button groove 863, as shown in FIGS. 28B and 29B. Accordingly, the body piece 810 of the switch means 800 moves toward the front of the device body 300, and the guide beam 523 moves from the lower rib 521a to the upper rib 521c along the inclined rib 521b. ) is located in. And the lifting wall 513 and the lifting block 510 descend to the lower part of the device body 300 as shown by the arrow.

Afterwards, the user can press the operation button 620 and print the design on the surface of the printing medium shown in FIG. 30B.

In the above use mode, the height between the surface of the printing medium and the print head (PH) is high, so even if the surface of the printing medium, such as human skin, is slightly changed by being pressed, as shown in Figure 30b, the surface of the printing medium and the print head (PH) are high. ) is ensured so that the design does not come into contact, so the design can be printed clearly.

Meanwhile, referring to FIGS. 29A and 30A, the height difference between the lower surface of the lifting block 510 and the lower surface of the print head (PH) does not show a significant difference. To be precise, the height difference between the lower surface of the lifting block 510 and the print head (PH) is maintained at a distance of W1, which will be discussed below.

Now, referring to FIGS. 29b and 30b, after the height adjustment module 500 operates, the lifting block 510 is in a lowered state, so there is a gap between the lower surface of the lifting block 510 and the lower surface of the print head (PH). The height difference becomes larger. Precisely, the height difference between the lower surface of the lifting block 510 and the print head (PH) was adjusted to maintain a distance equal to W2, which will be discussed below.

At this time, the first roller 541 and the second roller 543 are disposed in the block groove 511 of the lifting block 510, so that the print head (PH) prints in both the raised and lowered states of the lifting block 510. The surface of the medium can be moved smoothly at a certain distance.

Additionally, in FIGS. 29A to 30B, the printing media are indicated as G1 and G2, which may be classified according to the material of the printing media.

For example, the printing medium G1 may be a relatively flat or hard material, and may include, for example, a wall, a wooden board, etc. in addition to the paper and fabric described above. Additionally, the printing medium G2 may be a soft material, and for example, in addition to the above-described human skin, it may include various materials whose surfaces may be deformed during the printing process, such as rubber and leather.

In addition, in FIGS. 29A to 30B, the distance between the print head (PH) and the printing medium is indicated as W1 and W2, which can be defined as the distance at which the print head (PH) can print on the printing medium. Hereinafter, W1 and W2 will be described by designating them as printing distance or jetting distance.

Referring to FIG. 29a, when the print medium (G1) is relatively flat or made of a hard material, maintaining the jetting distance (W1) is sufficient for the print head (PH) to print smoothly on the print medium (G1). do. At this time, the lifting block 510 may be located in the module receiving portion 331 of the support frame 330 in an elevated state.

Referring to FIG. 29b, if the printing medium G2 is made of a soft material and deformation occurs during the printing process, the jetting distance W2 needs to be adjusted in consideration of the surface deformation of the printing medium G2.

As described above, the user pushes the button portion 830 into the button groove 863 to lower the lifting wall 513 and the lifting block 510. As the lifting block 510 descends, the first roller 541 and the second roller 543 also descend, and at this time, the receiving frame 320 is fixed to the upper part of the support frame 330, so the receiving frame 320 ) The print head (PH) of the ink cartridge (K) installed inside does not descend.

Accordingly, the jetting distance between the print head (PH) and the printing medium (G2) is adjusted from W1 to W2. Afterwards, when the user holds the printing device 100 and moves it along the surface of the printing medium, the jetting distance (W2) is maintained between the print head (PH) and the printing medium (G2) even if there is a change in the surface of the printing medium, so that the design can be You can print clearly.

Referring to FIGS. 30A and 30B, the operation of the printer device according to surface changes for each printing medium is shown.

Referring to FIG. 30A, when the printing medium (G1) is relatively flat or made of a hard material, the user holds the printing device 100 and moves it in the direction of the arrow without operating the height adjustment module 500 to print the design on the printing medium ( G1) can be printed. P1 shown in FIG. 30A represents the printing area and represents the area where the print head (PH) prints the design by injecting ink into the printing medium (G1) spaced at a predetermined interval.

At this time, the first roller 541 and the second roller 543 facilitate the surface movement of the printing medium (G1). Here, the jetting distance maintained between the print head (PH) and the printing medium (G1) is the jetting distance (W1) shown in FIG. 29A.

Referring to FIG. 30b, when the printing medium G2 is made of a soft material and the printing device 100 is moved in the direction of the arrow, the printing medium G2 is deformed due to the force applied by the user. In particular, when the first roller 541 and the second roller 543 move along the surface of the printing medium G2, severe compression may occur.

In Figure 30b, the user operated the height adjustment module 500 in consideration of the material of the printing medium (G2) to lower the lifting block 510. Accordingly, even if deformation occurs in the printing medium (G2), this degree of deformation is reflected, and ultimately, a predetermined gap is maintained between the print head (PH) and the printing medium (G2) in the printing area (P2).

P2 shown in FIG. 30B represents the printing area and represents the area where the print head (PH) prints the design by injecting ink into the printing medium (G2) spaced at a predetermined interval.

By adjusting the jetting distance W2, the printing area P1 shown in FIG. 30A and the printing area P2 shown in FIG. 30B can be formed with a relatively equal distance between the print head PH and the printing medium. Therefore, even if the material of the printing medium changes, a design with relatively the same clear quality can be printed on the surface of the printing medium.

According to at least one of the above-described embodiments of the present invention, the height between the print head of the ink cartridge and the printing medium can be adjusted depending on the material of the printing medium, which has the advantage of improving the quality of the printed design. Additionally, it has the advantage of improving user convenience by allowing the user to easily remove the ink cartridge and allowing the user to easily identify the current use mode with the naked eye.
