Abstract: A liquid ejection apparatus includes a pressure sensor and a determining unit. The pressure sensor is configured to detect a pressure in an ink supply path for use in supplying ink from an ink tank to a recording head. The determining unit determines whether the ink supply path is anomalous based on a result of detection of the pressure in the ink supply path by the pressure sensor performed in response to application of a fluctuating pressure to the ink in the ink tank.

Abstract: A fail-safe capability is realized that not only forestalls the execution by the user of the head replacement operation in an erroneous sequence while the printing apparatus is in operation but also prevents the splashing of ink even if the user attempts to inadvertently replace the print head. For this purpose, the ink supply and the opening and closing of the print head replacement cover are performed by a predetermined rotation of one drive source.

Abstract: A burden on a user when changing sheets such as with an ink jet printer and the like is reduced, and the necessary stack space is secured without considering the step difference up to the mounting surface of an ejected paper tray worth of the amount of curls for sheets that easily curls such as post cards and the like. Thus, enlargement of the apparatus and increase in the manufacturing cost are suppressed, and is easily adopted for low cost type for mass consumption.

Abstract: A recording apparatus includes a recording-head replacing portion, a feeding unit that feeds a recording sheet, and an eject unit that ejects the recording sheet on a front side of the apparatus. The apparatus further includes a head mount that is movable between the carriage and the head-replacing portion while the recording head is mounted on the head mount, a head-lowering member that moves the recording head from the carriage to the head mount, and a head-pushing member that moves the recording head mounted from the head mount to the carriage.

Abstract: A carriage moving device includes a main guide member configured to guide movement of a carriage, a sub-guide member configured to guide the movement of the carriage and to regulate rotation of the carriage, and an engaging portion provided in the carriage and configured to slide relative to the main guide member. The main guide member includes a first flat face extending vertically, and a second flat face extending in a direction such that a vertical upper portion is farther from the first flat face than a vertical lower portion. The engaging portion is in contact with the first and second flat faces.

Abstract: A container for containing consumable supplies for the use of an ink jet printer includes an ink containing portion for containing an ink, and an ink communication member for causing ink communication by piercing the ink containing portion when the container is attached to the printer. Before the container is attached to the printer, the ink containing portion can contain the ink sealingly and independently of the outside. As a result, ink leakage during distribution of the container can be prevented and the ink containing portion having, e.g., a bag-like shape, can be produced by a simple process, for sealingly containing the ink.

Abstract: Down-sizing of a pump for sucking two types of different fluids is realized. The pump is provided with a cylinder pump having a cylinder main body having a reciprocally movable piston, a first cylinder chamber partitioned at one side of the piston for being introduced with a first fluid, and a second cylinder chamber partitioned at the other side of the piston for being introduced with a second fluid, and piston driving means for reciprocally moving the piston of the cylinder pump.

Abstract: A printer in which an inkjet recording head is scanned with relation to a printing medium includes an ink supply member to be connected with a reserving portion arranged within the recording head when the inkjet recording head is positioned at the end portion of a scanning area, and a suction member for providing a suction power in introducing inks from the ink supply member to the reserving portion. Associated with a movement of the inkjet recording head to the end portion, those members are connected to the inkjet recording head at a different time. Herewith, in comparison with the case where those members are connected to the inkjet recording head at the same time, a force for moving the inkjet recording head required for such connection is reduced to achieve a downsizing of a driving source for generating the movement.

Abstract: The present invention provides a cleaning device for an inkjet printing head and a method for cleaning such a head; a wiper to be used for cleaning the inkjet printing head; and an inkjet printing apparatus having such a wiper for preventing the deposition of ink on the side of a printing head. Slits facing to the side of the printing head are formed on a wiper made of a sheet of rubber, which moves relatively with the printing head.

Abstract: A container for containing consumable supplies for the use of an ink jet printer includes an ink containing portion for containing an ink, and an ink communication member for causing an ink communication by sticking into the ink containing portion when the container is attached to the printer. Herewith, before the container is attached with the printer, the ink containing portion can contain an ink sealingly and independently of the outside. As a result, an ink leakage during a distribution of the container can be prevented and the ink containing portion having e.g. a bag-like shape can be produced by a simple process, for containing an ink sealingly.

Abstract: A printer in which an inkjet recording head is scanned with relation to a printing medium includes an ink supply member to be connected with a reserving portion arranged within the recording head when the inkjet recording head is positioned at the end portion of a scanning area, and a suction member for functioning a suction power in introducing inks from the ink supply member to the reserving portion. Associating with a movement of the inkjet recording head to the end portion, those members are connected to the inkjet recording head in delaying the time. Herewith, in comparison with the case where those members are connected to the inkjet recording head at the same time, a force for moving the inkjet recording head required to such connection is reduced to achieve a down sizing of a driving source for generating the movement.
