That is, the pressure adjusting handle 244 may adjust the pressing force of the spring 242 through the protrusions 244a of different thickness while rotating by the user's external force.

The magnet installation block 230 is a component that forms an installation part of the magnet member 300 to be described later, and is substantially fixed to the pressure block 220 in the form of a rectangular parallelepiped, and rotates together with the pressure block 220.

A second magnet 320 to be described later may be installed on the magnet installation block 230, and a third magnet 330 to be described later may be additionally installed.

The magnet member 300 secures the TPH module 10 to the lifting plate 100 via a magnetic force, and at the same time rotates the lifting plate 100 when the magnet installation block 230 constituting the above-described pressing member 200 is rotated. ) Is a component that elevates through magnetic force.

For example, the magnet member 300 may include a first magnet 310 and a second magnet 320.

The first magnet 310 is fixed to the upper surface of the lifting plate 100 and is a component that fixes the TPH module 10 to the bottom surface of the lifting plate 100 through magnetic force, and when the lifting plate 100 is elevated It is a component that fixes the 100 in an elevated state.

The first magnet 310 may be fixed to the magnet holder 311 fixed to the upper surface of the lift plate 100, as shown in FIG. 4, of a permanent magnet having a set polarity or of a polarity set by power supply. It may be composed of an electromagnet with magnetic force.

The second magnet 320 is a component that generates an attraction action by the first magnet 310 and a magnetic force, and has a different polarity from the first magnet 310 and has the above-described pressing member as shown in FIG. 3 ( 200) may be fixed to the front of the magnet installation block 220 constituting the.

Here, the meaning that the second magnet 320 has a different polarity from the first magnet 310 means that the surface of the second magnet 320 has a polarity opposite to that of the first magnet 310.

As the second magnet 320 has a different polarity from the first magnet 310, as shown in FIG. 4, when the pressing block 220 rotates in one direction, it faces the first magnet 310 while exerting magnetic force. The manpower caused by this can work.

And, the second magnet 320, as shown in Figure 6 by pulling the first magnet 310 through the attraction action to raise the lifting plate 100 together with the TPH module 10, the lifting plate 100 ) Can be fixed in a raised state.

In addition, when the second magnet 320 is lowered to the lifting plate 100, the magnet installation block 230 rotates after being separated from the first magnet 310 by the rotation of the lever 211 by the user. Accordingly, as the attraction action with the first magnet 310 disappears, the descending of the lifting plate 100 may be allowed.

The second magnet 320 may be composed of a permanent magnet having a set polarity or an electromagnet having a magnetic force of a polarity set by power supply. Meanwhile, FIG. 8 is a longitudinal sectional view showing another embodiment of the magnet member 300 to be.

Referring to FIG. 8, the magnet member 300 may further include a third magnet 330.

The third magnet 330 is a component for descending the lifting plate 100 through the repulsive action by the first magnet 310 and the magnetic force.

Specifically, the third magnet 330 may be fixed to the bottom surface of the magnet installation block 230 while having the same polarity as the first magnet 310, and the lifting plate by rotation in the opposite direction of the pressing block 220 ( 100) when falling, it may face the first magnet 310.

Here, the meaning that the third magnet 330 has the same polarity as the first magnet 310 means that the surface of the third magnet 330 has the same polarity as the surface of the first magnet 310.

As the third magnet 330 has the same polarity as the first magnet 310, the repulsive force by the magnetic force may act while facing the first magnet 310, and the first magnet 310 may be applied through the repulsive action. By pushing, the lifting plate 100 can be lowered together with the TPH module 10.

Here, the third magnet 330 may be composed of a permanent magnet having a set polarity or an electromagnet having a magnetic force of a polarity set by power supply.

Meanwhile, the magnet member 300 may be configured of only the second magnet 320 while the above-described configuration of the first magnet 310 is omitted.

At this time, the above-mentioned lifting plate 100 may be formed of a metal material, and the above-described TPH module 10 may be fixed by fastening by screws, fixing by pressing, or fixing by double-sided tape.

That is, when the lifting plate 100 is formed of a metal material and faces the above-described second magnet 320, it may be raised by the magnetic force of the second magnet 320, and the magnet installation block 220 may rotate. In this case, the second magnet 320 may be separated and descended.

On the other hand, the magnet member 300 may be composed of only the first magnet 310 while the above-described configuration of the second magnet 320 is omitted.

At this time, the above-described magnet installation block 220 may be formed of only a metal material, and the above-described TPH module 10 may be fixed to the lifting plate 100 by the magnetic force of the first magnet 310. .

Accordingly, when the first magnet 310 faces the front surface of the magnet mounting block 220 of a metal material, the lifting plate 100 rises toward the magnet mounting block 220 by the magnetic force of the first magnet 310. When the magnet mounting block 220 rotates, the first magnet 310 may be lowered while being separated from the magnet mounting block 220.

The process of raising and lowering the TPH module 10 for a printing apparatus according to an embodiment including the above components will be described.

When the TPH module 10 is spaced apart from the platen roller 30 for exchanging printing paper or separating the fullerton roller 30, the user presses the rotary shaft 210 by rotating it in one direction through the lever 211. The block 220 is separated from the upper surface of the lifting plate 100.

Accordingly, the magnet installation block 230 is rotated in one direction together with the pressure block 220, the second magnet 320 is to face the first magnet 310 by the rotation of the magnet installation block 230 Can be.

At this time, since the second magnet 320 faces the first magnet 310 and the attractive force due to the magnetic force acts, the first magnet 310 may be attracted to be in close contact.

Accordingly, the TPH module 10 may be spaced apart from the platen roller 30 while rising together with the first magnet 310 and the lifting plate 100.

When returning the TPH module 10 to its original position, the user rotates the lever 211 in the opposite direction to rotate the pressure block 220, and the second magnet 320 is the pressure block 220 and the magnet installation block The lowering of the lifting plate 100 may be allowed while being separated from the first magnet 310 by rotation in the opposite direction of 230.

At this time, when the third magnet 330 is installed on the magnet installation block 230, the lifting plate 100 is smooth as the third magnet 330 faces the first magnet 310 and the repulsive force by the magnetic force acts. Can descend.

As described above, according to the installation structure of the TPH module for a printing apparatus according to an embodiment, the first magnet 310 and the second magnet 320 constituting the magnet member 300 have different polarities. Accordingly, when the pressing member 200 is rotated, it can be fixed in an elevated state due to an attraction force by magnetic force, and accordingly, the lift plate 100 can be raised and returned through a simplified configuration.
