ェットヘッドへの悪影響を及ぼす欠点を有していた。Each time these nozzle caps and cleaners are operated, they become contaminated by ink discharged from the nozzles and surrounding dust and dirt. To remove these stains, methods such as scraping with a thin plate or wiping with a porous material have been used, but since these are both installed on the printer body, dirt can accumulate over long periods of use. This has the disadvantage of having an adverse effect on the printer itself or the inkjet head.

Printing is performed by applying a high voltage to the piezoelectric element 29 using an ink-on-demand type inkjet head to eject ink from the nozzle 3a. Ink is stored in tank 4 or 5. The printing means 2 is moved in parallel to the printing paper 6 by the drive of the motor 7 via the gears 9 and 11 and the lobe 13. The motor 7 is a pulse motor that performs stepwise rotational motion in response to pulse input, and the printing means 2 also performs reciprocating motion in synchronization with the motor 7.

滑りを生ずる。As shown in FIG. 4, the nozzle cap 21 is a cylindrical rotating member, and a resilient member 24 is inserted into a frame 23. As shown in FIG. The rotating shaft 19 and the coil spring 22 are in close contact with each other, and one end 22 (E) of the coil spring 22 is engaged with the notch 23α of the frame 23. As the motor 18 rotates, the rotating shaft 19 rotates clockwise as shown by the arrow. The coil spring 22 functions as a spring clutch and is wound around the rotating shaft 19, and the end 22a of the coil spring 22 hooks the notch 23α of the frame 23, causing the nozzle to rotate in the direction of the arrow. The camp 21 rotates in the direction of the arrow.Also, when paper is fed, it rotates counterclockwise, but in this case, the close contact between the rotating shaft 19 and the coil spring 22 becomes loose, causing slippage between them.
よって回転軸１９の回転は、ノズルキャップ２１に伝達
されない。Therefore, the rotation of the rotating shaft 19 is not transmitted to the nozzle cap 21.

Therefore, as shown in FIG. 3, when the nozzles 3α, 3b of the inkjet head B are pressed against the nozzle cap 21, the different color inks of the pair of inkjet heads B do not mix.

なってもよい。Clean the tip of 3b by rubbing it. At this time the third
By applying a high voltage to the piezoelectric element 29α shown in the figure,
Spray more ink. There are several methods of ejecting this, such as ejecting it as ink droplets similar to a printing nozzle, ejecting it as ink droplets larger than a printing nozzle, and ejecting it so that it flows from the nozzle rather than ink droplets. In this embodiment, the third ink flows out. The conditions at this time were 5 vertical lines, 10 horizontal words,
A voltage of approximately 50 V is applied to the piezoelectric element 29α with a thickness of 0.2 mm.
Control is performed to repeat application of rns and off for 1 ms. The cross section of the tip of the nozzle 3b is a square with one side of 02 squares. As a result, the ink ejected from the nozzle 6b accumulates on the tip surface of the nozzle 3b, as shown in FIG. The cleaner 24α of the nozzle gap 21 rotating in the direction of arrow G cleans the tip surface of the nozzle 3α while sweeping away ink. New ink flows out from the nozzle 3b, so by repeating the cleaning, the highly viscous ink, dried ink, dust, clumps, etc. adhering to the tip surface of the nozzle 6α are completely cleaned, and the inkjet head 3 is completely cleaned. This ensures proper performance. At this time, cleaning may be performed while ejecting ink from the printing nozzle 3cL instead of the nozzle 3b.

〜５００ ｒ、ｐｏｍ。Next, if air bubbles occur inside the ink side head 3 or if the viscosity of the ink in the nozzle 3a increases, cleaning is performed while jetting ink from both the nozzle 6cL and the nozzle 3b. This means that the ink that oozes out little by little from the nozzle 3cL comes from the cleaner 24.
This is because by repeating jetting and cleaning, air bubbles, viscous ink, etc. inside the inkjet head 3 are removed, and the inkjet head 3 is completely restored to a printable state. The ink that falls down the end face of the nozzle passes through the channel filter G and is collected into a waste liquid tank (not shown). Further, ink, dirt, etc. adhering to the nozzle cap 21 are removed by the porous member 25. As shown in FIG. 6, this porous member 25 is integrated with the tanks 4 and 5, and is replaced at the same time as the tanks 4 and 5.
It is possible to reliably remove dirt adhering to 1. Further, since the porous member 25 is provided in each of the pair of inkjet heads B, even when two-color printing is performed, the colors of the respective inks will not be mixed. The outer diameter of the nozzle cap 21 is 30 mm, and the rotation speed is 100 mm.

This has the effect of reliably removing dirt adhering to the nozzle cap and cleaner.
