摘要： PROBLEM TO BE SOLVED: To provide an ink-jet recording apparatus which can surely prevent an ink leakage in a state that a waste ink tank is loaded. SOLUTION: An unnecessary ink sucked from a cap member is sent from an inlet part 40 into the waste ink tank 32. The simultaneously entering air is discharged outside from a discharge part 44. If the ink-jet recording apparatus falls sideways or is turned upside down when transported or the like, the discharge part 44 positioned to an upper face is brought down, whereby the unnecessary ink is feared to leak from an air communication hole of the discharge part 44. The air communication hole of the discharge part 44 is formed in a corner part 42 of the upper face 32A to face more outward than any of planes 32A, 32B and 32C. Moreover, a shutting member is set for shutting the air communication hole when the hole is directed down. The air communication hole alike is directed down and can be shut by the shutting member when the discharge part 44 is brought down. The ink leakage can be surely prevented.

摘要： PROBLEM TO BE SOLVED: To obtain an ink jet head, and a method of manufacture, in which reliability and ejection characteristics are enhanced with regard to clogging with ink by preventing adhesive from projecting into a nozzle or an ink channel at the time of bonding a substrate. SOLUTION: A groove 40 is made in the ink channel substrate 32 of an ink jet head 10 along with the groove 38 of an ink channel 28 being made by ODE process. Adhesive 42 transferred onto the bonding face 32A of the ink channel substrate 32 is pressed to enters the groove 40 when an element substrate 12 is bonded and prevented from projecting into a nozzle 26 or the ink channel 28.

摘要： PURPOSE:To obtain a high-efficiency ink supply device contriving stabilization of an ink supply performance and also suppression of an effect of a change in ambient environment by a simple construction. CONSTITUTION:An ink tank 3 is composed of an ink chamber 5 and an ink absorber chamber 6 provided with an air connecting hole 9 and loaded with an ink absorber 8. Firstly, ink in the ink absorber 8 is consumed. When the ink in the ink absorber 8 is almost exhaused, air is turned to bubbles when passing through a meniscus forming part 10 and moved to the ink chamber 5. An ink pressure is kept constant by the surface tension of the meniscus forming part 10. The meniscus forming part 10 is provided at a connecting part of the side wall of the ink chamber 5 to the ink absorber chamber 6 in the vicinity of the bottom, thus being disposed substantially vertically. Therefore, produced bubbles immediately move upwards, and there is no possibility that the surface of the meniscus forming part 10 may be covered with bubbles. In addition, the surface is always wet in contact with the ink in the ink chamber 5 for preventing the break of a meniscus.

摘要： PURPOSE:To accurately detect the residual amt. of the ink in an ink tank while satisfying the cost reduction and miniaturization of an ink residual amt. detector and a demand reducing the wasteful consumption ink at a time of ink emitting capacity recovery processing. CONSTITUTION:In an ink jet recording apparatus consisting of an ink jet head 2 and the ink tank 3 supplying ink to the ink jet head 2 and having the ink jet cartridge 1 positioned and mounted with respect to a scanning carriage 4 in a freely detachable manner, at least a part of the joint member 5 having the ink jet head 2 and the ink tank 3 connected thereto is constituted of a light permeable member 6. An optical detection means 8 optically detecting the presence of the ink in the ink passage 7 facing the light permeable member 6 is directly positioned and fixed on the scanning carriage 4.
