クを収納させる方法があった。Conventionally, the ink is composed of a thermal head and an ink film in which many micropores are formed, and the ink held in the ink film is heated by the thermal head to instantly vaporize the ink. The ink application mechanism of a recording device that performs recording by ejecting ink may include a method in which a pulley is embedded in an ink container and stored directly in the film micropores, and a method in which the ink in the ink container is absorbed by an ink absorber to absorb the ink. There has been a method in which ink is accommodated within the film's micropores by bringing an absorber into contact with the film.

At the center, the ink application section and the washer liquid application section are in contact with each other via the outer cylinder. During printing, due to friction caused by film movement, the ink absorber in the ink application section comes into contact with the film, supplying ink to the fine pores of the film, and printing can be performed. When not printing, the film is moved in the opposite direction so that the washer liquid application portion comes into contact with the film, and the area around the thermal head is cleaned by the film and the cleaning liquid adhering to the film.

。DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the inkjet power cent according to the present invention will be described below with reference to the drawings. FIG. 1 is a top sectional view showing an inkjet cassette according to the present invention. A case 1 having a box-like shape as a whole is formed on the second cassette, and is detachably attached to a carriage (not shown) of the recording apparatus main body. It is something. An opening 2 is formed at the tip of the case l, in which an ink supply section 3 and a washer liquid supply section 4 are buried, and the ink supply section and the ink supply section are embedded in the ink absorber 6.
The washer liquid absorber 7 is impregnated with the washer liquid from the washer liquid supply section. The ink absorber 6 and the washer liquid absorber 7 are held in a cylinder 8, and the ink absorber 6. A part of the washer liquid absorber 7 is exposed, and the ink supply section 3. They are rotatably attached to one end of each Wofsher liquid supply section 4. Countless holes are formed on the surface of the cylinder 8,
An ink absorber 6. The liquid leaks into the washer liquid absorber 7 smoothly. In addition, a stopper/spring hook 9 is formed in a part of the tube 8, and when not printing, the pressure of the spring 10 is applied to the tube 8.
rotates, and the cutout portion becomes sealed in the direction of the ink supply section 3 and the washer fluid supply section 4. A pulley 12 is rotatably provided within the case l. As shown in FIG. 1, this pulley 12 is provided with a flexible endless film 11 made of a metal or organic material having a large number of small holes (the diameter of the holes is approximately 10 to 200 μm), and is removable. The film 11 is attached to the opening 2 of the case 1.
It is stretched around a pair of guide rollers 14 formed at both ends of the. The film 1 has a large number of micropores formed collectively with a constant length in the longitudinal direction of the film 11. The boot 2 is formed in the center of the pulley 12 of the case 1 and is rotatably supported with a loose fit. Further, the center portion of the pulley is formed in the shape of an internal gear, and rotates while meshing with the drive shaft of the recording apparatus main body carriage (not shown).

る。During printing, the endless film 11 closes to the opening 2 of the case 1.
In order to move in the direction of arrow A while being stretched between a pair of guide rollers 14 formed at both ends of the ink supply section 3, the tube 8 of the ink supply section 3 resists the elastic force of the spring 10 and generates friction with the film 11. The exposed portion of the ink absorber 6 is brought into contact with the film 11. Even if the stopper/spring hook 9 tries to rotate further, it comes into contact with the inner wall of the case of the ink supply section or the washer liquid supply section as a gas stopper, and the contact state is maintained without further rotation.

れる。After printing or when cleaning is performed, by rotating the pulley 12 in the direction of arrow B in FIG. It rotates in the same way as the cylinder,
The cylinder of the washer liquid absorber 7 is exposed and comes into contact with the film 11, while the cylinder of the ink supply section 3 rotates in the opposite direction and becomes sealed inside the ink supply section 3, so that only the washer liquid is left in an endless state. The film 11 is supplied and cleaned.
