Disclosed is an ink tank coupling method for an ink jet recording apparatus including a recording head, an ink supply needle, and a moving unit for moving the ink supply needle to a predetermined position, the recording apparatus being able to detachably mount an ink tank containing ink supplied to the recording head. The method includes a step of holding and fixing the ink tank to a predetermined position by releasing a movement preventing unit which prevents movement of the ink supply needle caused by the moving unit, and pressing the ink tank to abut a reference surface with an operation of attaching the ink tank to the recording apparatus, and a step of inserting the ink supply needle to the predetermined position in the ink tank by the moving unit after the holding and fixing step. Disclosed also is an ink jet recording apparatus and an ink tank adapted for carrying out the ink tank coupling method with a relatively simple construction and with higher reliability of the coupling, while allowing users to recognize the proper coupling of the ink tank.

An ink tank includes an ink containing portion for containing ink, a bottom surface provided with three projections for supporting the ink tank, an ink supply portion for leading ink out of the ink containing portion to the exterior a top surface opposing to said bottom surface, and a plurality of lateral surfaces adjacent to the bottom and top surfaces. The plurality of lateral surfaces include one set of opposing surfaces extended in a lengthwise direction of the ink tank. A grip portion is provided at one end of the ink tank in the lengthwise direction of insertion thereof. Two of the three projections are provided on the bottom surface in an opposed relation in areas near the opposing surfaces of the plurality of lateral surfaces, the ink supply portion being provided in an area of the top surface opposed to an area located on or within lines connecting the three projections.

A liquid ejection printing apparatus performing printing by ejecting a liquid toward a printing medium includes a liquid ejection head portion having a liquid ejecting printing head ejecting a liquid and a first tank holding the liquid to be supplied to the head, a second tank holding a liquid to be supplied to the first tank and having an atmosphere communicating opening for introducing an atmospheric air, a third tank receiving the liquid from the first tank and capable of supplying the liquid to the second tank, a first liquid supply passage for communicating the first tank and the second tank, a second liquid supply passage for communicating the second tank and the third tank, a third liquid supply passage for communicating the third tank to the first tank, the first tank and the third tank each forming an enclosed space excluding supply passages connected respectively thereto, a pump capable of sucking a gas within the third tank provided in a passage other than the first, second and third supply passages and a first valve provided in the second supply passage for opening and closing the second liquid supply passage, and a second valve provided in the third tank for communicating the gas within the third tank to outside.
摘要:
A printing apparatus employs a photosensitive drum for forming a latent image on a surface region thereof, a developing unit for forming a protrusion by selectively causing ink repellent particles to adhere onto the surface region carrying the latent image formed thereon, an ink roller for feeding ink to the protrusion on the surface of the photosensitive drum, a blanket cylinder for receiving the ink from the projected region, an impression cylinder for pressing the ink on the surface of the blanket cylinder when the ink is transferred onto a sheet of paper, and a conveying unit for conveying the sheet of paper. The surface of the ink repellent particles has a property of repelling the ink, while the surface of the photosensitive drum has a property of not repelling the ink.
摘要:
Provided is a reaction treatment apparatus in which, in a case of mixing a plurality of solutions in a microchip used in a biochemical reaction system, an electric field generation area for changing solute concentration distribution in the solutions is provided in a solution upstream fluid path. Diffusion between the solutions is accelerated by bringing an area with a high solute concentration into contact with another solution. This may shorten a time required for mixing the solutions.

A nucleic acid sample testing apparatus includes a transport carrier, which can move along a transport guide in a horizontal direction perpendicular to a direction of movement of a pipette unit. On the transport carrier, a tray equipped with a DNA microarray as a reaction container and a reagent container are arranged without being connected with each other. In addition, within a range of movement of the transport carrier and also within a movable range of the pipette unit, a processing section for carrying out a hybridization reaction is arranged. Above the range of movement of the transport carrier, a transport unit is arranged while being connected with a transport guide. The transport unit can move in the same direction as the moving direction of the pipette unit along the transport guide. In addition, a detecting section is arranged on the movable range of the transport unit.
摘要:
A biochemical processing apparatus includes a plurality of reaction areas of different types, a pipette for dispensing a liquid, a pipette chip removably attachable on the pipette, and pipette chip storage spaces each capable of holding the pipette chip. The pipette chip storage spaces are provided in the plurality of reaction areas.
摘要:
An ink drying apparatus is provided with a gas passage through which a printed material to which ink is attached passes. Further, a flow applying unit configured to create a flow of gas in the gas passage in a predetermined direction, a heating unit configured to heat the gas in the gas passage, and a solvent removing unit configured to remove a solvent in the ink from the gas passage are provided. In the ink drying apparatus, the heating unit and the solvent removing unit are associated with each other such that heat can transfer from the solvent removing unit to the heating unit by a heat transmission unit.
摘要:
When different liquids are charged in a plurality of nozzles, the liquids are drawn by suction or pushed out reliably from the nozzles, so that the liquids collected by suction or pushing out can be reused. For this purpose, a removing unit, which has a cap that operates to cover nozzle discharge ports and to come into tight contact with a head, is provided. Suction is performed from each nozzle separately. Different collection tubes and collection tanks are provided for the removing unit. A liquid having the same liquid composition is accumulated in one collection tank for the same liquid composition via the collection tube of a liquid channel for the same liquid composition.
