Extend it upward to about the halfway point. 26 is a piston of the suction pump, and this piston 26 has a narrow diameter portion 28 that can slide through the opening 20A and the sealing groove 23, and its upper end is fixed to the lever 5 described above. The lower end of the piston 26 has a large diameter portion 27 that fits into the suction chamber 22, and a peripheral portion of the large diameter portion 27 that overhangs the narrow diameter portion 28 passes through the large diameter portion 27 in the axial direction. A passage 29 is opened, and a valve 30 that opens and closes in response to pressure difference fluctuations at the openings at both ends of the passage 29 is installed at the lower end of the passage 29 on the suction chamber 22 side. In addition, the large diameter portion 2
An O-ring 31 is attached to the outer wall of 7 to seal between the outer wall and the suction chamber 22. Further, a recess 32 is cut out in the bottom surface of the large diameter portion 27 of the piston 26 on the suction chamber side, and a compression spring 33 is attached between the recess 32 and the base 21.

At the same time, the nozzle 3 penetrates into the hole 9A and faces the ink absorber 6 at the rear of the cap 9. Since ink is absorbed in this ink absorber 6,
The inside of the hole 9A, and thus the area around the nozzle 3, is always filled with ink vapor, and the tip of the nozzle 3 never dries.

4により確実に密封される。 On the other hand, if ink ejection failure occurs due to causes such as receding of the meniscus of the ink liquid level or generation of bubbles in the nozzle 3, the piston 23 should be pushed down as shown in FIG. , a negative pressure is generated in the cavity 36, and the negative pressure sucks the tip of the nozzle 3, and the ink is drawn into the nozzle 3.
Discharge outward from the To do this, first, as shown in FIGS. 3A and 3B, the elastic cap 9 at the tip of the cap slide 4 is brought into pressure contact with the recording head 1, and in this state the lever 5 is moved between the cap fixing plate 12 and the cap slide 4. The piston 26 is pushed down by sliding the piston 26 downward. At this time, the large diameter portion 27 of the piston 26 and the pump body 2
Since the space 36 formed between the piston 26 and the upper end of the piston 26 becomes negative pressure due to volume expansion due to the depression of the piston 26, the inside of the passage 6A connected to this space 36 also becomes negative pressure. Further, since the tank (not shown) that supplies ink to the recording head 1 is always open to the atmosphere, the ink in the nozzle 3 is ejected outward from the nozzle 3 due to the pressure difference between the front and rear sides of the nozzle 3. Therefore,
For example, when the meniscus is receding, the receding meniscus can be sucked and return to a normal state, thereby resolving the ejection failure. Next, when the piston 26 is released, the compression spring 33 causes the piston 26 to return upward as shown by the arrow in FIG. At this time, since the valve 30 is made of a film with a thickness of several tens of micrometers, it responds sensitively to fluctuations in the pressure difference between the upper and lower sides, and the valve 30 becomes open, and the ink sucked into the cavity 36 passes through the passage 29. Hole 37 provided below the pump body 20
is discharged to the outside. Note that by making the line resistance of the passage 29 smaller than the line resistance of the suction tube 35, the ink accumulated in the space 36 can be removed from the passage 2.
9 can be easily discharged. The side wall 2A at the tip of the cartridge 2 is chamfered, the cap slide 4 that comes into contact with the side wall 2A is also provided with a recess 8, the recording head 1 is provided with a recess 1A, and the elastic cap 9 is also provided with a convex tip. Carriage 2
Even if there is some misalignment between the cap slide 4 and the cap slide 4, the unevenness is corrected by these uneven portions, and the recording head 1 is reliably sealed by the cap slide 4.

Since the nozzle 3 at the tip of the nozzle 3 is covered with a cap slide 4 having an absorber 6 impregnated with ink inside, the tip of the nozzle 3 does not dry out, and printing can be performed immediately when reusing it. can.
In addition, in the present invention, since the capping device is provided with a nozzle suction device, when carrying an electronic device with an inkjet printer, shocks and vibrations may be applied to the inkjet printer, and the inkjet printer may be tilted and the inside of the nozzle may be removed. Even if a meniscus retreats or air bubbles are generated, causing ejection failure, the ejection failure can be easily removed by ejecting the ink inside the nozzle to the outside using a nozzle suction device during reuse. Furthermore, since this nozzle suction device does not require any special equipment such as a motor, solenoid, or pump, it is possible to provide an inexpensive and highly reliable capping device.
