Abstract: An ink cartridge is partitioned into a negative pressure generator chamber containing a negative pressure generator and a storage chamber containing an ink bag. The ink bag stores ink and supplies the ink to the negative pressure generator chamber through an ink port. The negative pressure generator absorbs and holds the ink by its capillary force, to keep pressure inside nozzles of a recording head negative to atmospheric pressure. Through a first air introduction hole, the air is introduced into the negative pressure generator chamber as the ink in the negative pressure generator chamber decreases. Through a second air introduction hole, the air is introduced into the storage chamber as the ink in the ink bag decreases. So variations in pressure inside the nozzles are suppressed, which makes ink discharge from the nozzles stable.

Abstract: To fill the ink cartridge with the ink, a first air introduction hole of a negative pressure generator chamber is sealed up, and a pressure pump is connected to a second air introduction hole of a storage chamber, to raise pressure inside the storage chamber so as to exhaust air out of an ink bag. While keeping the storage chamber under the high pressure, the second air introduction hole is sealed up, the first air introduction hole is opened, and an ink filling pump is activated to inject the ink through an ink outlet into the negative pressure generator chamber. When a predetermined amount of ink is injected, the second air introduction hole is opened, and the ink filling pump is reactivated to fill up the ink bag as well as the negative pressure generator chamber with the ink.

Abstract: An ink cartridge, which is removably set in a printer, has an ink chamber storing ink, an absorbent chamber containing a sponge that absorbs the ink from the ink chamber and holds it, and a fuel chamber storing a liquid fuel to be supplied to a fuel cell of the printer.

Abstract: Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.
