Abstract: A liquid supply device includes a container, a boring part, an operation lever, a fixing member, and a coupling portion. The container includes a sealing film and is filled with a liquid. The boring part bores the sealing film of the container when the boring part is inserted into the container to discharge the liquid from the container and supply the liquid to a supply destination. The operation lever is connected to the boring part and operates the boring part so that the boring part is pulled out and inserted into the container. The fixing member fixes the operation lever when the boring part is inserted into the container. The coupling portion is installed in the container and is coupled with the operation lever when the operation lever is moved to the position where the boring part is inserted into the container to prevent the boring part from slipping.

The borer has a radial shape in the cross-sectional view and has a tilt part that is tilted toward the center of the radial shape at the tip to be inserted into the opening part of the liquid bag to bore the sealing film. The discharge stop part is arranged at the opening part of the liquid bag, has elasticity, and is provided with a slit having a minus symbol shape which is pressed and extended by the insertion of the borer.

Abstract: A liquid bag connecting member includes a support face and a holding part. The support face supports a bottom face of a liquid bag to be filled with a liquid and is arranged so that an opening part of the liquid bag faces in a gravity direction. The holding part is positioned lower than the support face in the gravity direction and holds the opening part. The holding part includes an opening into which the opening part is inserted. The liquid bag connecting member is connected to the liquid bag to have the liquid bag form into a funnel shape by using a difference of position between the support face and the holding part in the gravity direction.

Abstract: An inkjet recording device of the present invention includes an inkjet recording head, a first wiper, a first movement component and a control component. The inkjet recording head ejects ink droplets from a plurality of nozzles formed in a nozzle face. The first wiper abuts against the nozzle face and wipes the nozzle face. The first movement component relatively moves the first wiper, with respect to the nozzle face, along the nozzle face. The control component controls ejection of ink droplets from the nozzles and controls the first movement component. The control component moves the first wiper relative to the nozzle face while the control component causes ink droplets to be ejected from the nozzles at least toward the first wiper, causing the nozzle face to be wiped.

Abstract: An ink jet recording apparatus according to the present invention comprises an ink jet recording head for ejecting ink drops and a differential pressure valve provided in an ink feeding line connected to the ink jet recording head, the differential pressure valve generating a head back pressure in the ink jet recording head when ejecting no ink drop. Thus, the degree of freedom for the position of arrangement of an ink reservoir such as an ink tank connected to the ink feeding line is remarkably increased. Accordingly, it is possible to realize an ink jet recording apparatus of reduced size.

Abstract: An ink supply device is provided in correspondence with a recording head unit. The recording head unit has a recording head that ejects ink drops onto a recording medium on the basis of image information. Additionally the recording head unit has a sub ink tank provided with an air communication hole. The ink supply device includes an ink supply unit that supplies ink to the sub ink tank by reducing pressure on the inside of the sub ink tank through a pressure reduction part. A sealing part at least implements sealing of the air communication hole while the ink supply unit is reducing the pressure inside the sub ink tank.

Abstract: The invention provides an ink jet color recording apparatus capable of forming a good image by preventing solidification of ink. The ink jet color recording apparatus has a recovery step of recovering the injection function of a black nozzle by recovering black ink (pigment ink) remaining in the black nozzle into a black cap, and a supply step of supplying color ink (dye ink) to the black cap after the recovery step. Thus, the pigment ink recovered into the black cap by the recovery step can be made into mixed ink hard to dry, and further ink adhering to the inner wall of a suction hose connected to the black cap can be made into mixed ink residue hard to dry.

Abstract: A process for producing a 5-substituted-5,11-dihydro-debenzo [b,e] [1,4] oxazepine compound, wherein a [2-(2-bromobenzyloxy)phenyl]amide derivative having a substituent introduced through amido bond, the substituent locating at the 5-position of the final compound, as the starting material, is subjected to the intramolecular arylation and then the obtained product is reduced. In particular, (R)-1-[(4-methoxyphenyl)acetyl]pyrrolidine-2-carboxylic acid [2-(2-bromo benzyloxy)phenyl]amide is subjected to the intramolecular arylation to obtain (R)-[[2-(5,11-dihydro-dibenzo[b,e][1,4]oxazepine-5-carbonyl)pyrrolidin]-1-yl]-2-(4-methoxyphenyl)ethanone and then this product is reduced.
