  • Patent number: 6988838
    Abstract: An ink jet recording apparatus includes a disc tray which is contained in the recording device and on which a DVD disc is to be placed, a select switch for switching between a protruding state and an accommodated state of the disc tray, and a sheet feed tray on which recording sheets are placed and which are disposed substantially parallel to the disc tray, wherein the select switch, the sheet feed tray and the disc tray are operated on the front side of the ink jet recording apparatus. Further, a disc tray is movable in a printing direction and a tray discharge direction. When the disc tray is loaded into or unloaded from the recording device, the disc tray is transported in the tray discharge direction to move to outside an ink jet recording device. In other cases than the above case, the disc tray is accommodated in the ink jet recording device. Thus, the disc tray is transported into two directions.

  • Publication number: 20050052483
    Abstract: A recording system includes a line head having a plurality of nozzles arranged in a Y direction, a LF motor for feeding a role sheet in an X direction, and a CR motor for shifting a set position of the line head sequentially. When the set position of the line head is shifted by a given distance in the Y direction, the recording system converts image data in such a manner that an image is shifted in an opposite direction by a distance equal to the given distance so that the same image is recorded in different positions of the nozzles.

  • Publication number: 20040263545
    Abstract: A recording direction setting section successively sets recording directions of an image. A recording data generating section generates data for recording the image from the recording direction set by the recording direction setting section. A recording data analyzing section analyzes the operation of a line head performed when recording is carried out in accordance with the data generated by the recording data generating section. A recording direction determining section determines a recording direction so as to minimize the discharging frequency of a nozzle with the largest discharging frequency among a plurality of nozzles of the line head.

  • Patent number: 6604802
    Abstract: An inkjet recording apparatus includes a moving device which moves an inkjet head relative to a recording medium. When the head is moved relative to the recording medium by the moving device, a nozzle of the head ejects ink onto the recording medium, so that recording is carried out. The inkjet head includes (a) pressure chambers containing ink, (b) nozzles communicating through the pressure chambers, (c) piezoelectric elements, (d) piezoelectric actuators that deform to increase or decrease the capacities of the pressure chambers due to piezoelectric effect of the piezoelectric elements, and (e) a controller for driving the actuators at a frequency not less than 20 kHz. This structure allows the actuators to operate substantially noiseless, and an image can be recorded at higher speed.

  • Patent number: 5444474
    Abstract: An ink-jet cartridge for ink-jet printers includes a nozzle-cleaning mechanism built in the cartridge itself for removing residual ink and foreign matter, such as dust and dirt including paper powder, from nozzles. Since the built-in nozzle-cleaning mechanism is replaced automatically when the cartridge is replaced, and since the replacement of the cartridge generally takes place before the nozzle-cleaning mechanism deteriorates mainly due to contamination with ink, the nozzles are always kept clean and a reliable printing operation with high quality printing is insured throughout the service life of the cartridge.

  • Patent number: 5244295
    Abstract: A dot-matrix impact printer includes a print head in a housing for printing a recording sheet fed around a platen. The recording sheet is pressed against the platen by a sheet presser roller. A roller cover or a flap is disclosed as a sound insulating wall closely to the sheet presser roller and has an edge held against the housing. The space above the print head is closed by the housing, the platen, the sheet presser roller, and the platen, so that the impact noise produced when the printer is in operation will not leak out of the housing, while at the same time the recording sheet fed around the platen is not blocked by the closure mechanism.

  • Patent number: 5240336
    Abstract: A dot matrix printer of a dispersion printing type in which a printing noise is suppressed and dots arranged in longitudinal rows are driven while shifting the timing for every print wire dot. The present dot matrix printer is characterized by a construction in which respective print wires are driven at different timings within one pitch, and a space around a print head is surrounded by a housing and a platen, and a sound generated in the space is transmitted outside through walls. Further, the present dot matrix printer is characterized in that there is provided a memory storing printing intervals among the whole dots and print head conduction time, and the print head is driven in accordance with information read out of said memory in order to correct deviation of dot rows arranged in a longitudinal direction of the print head from perpendicularity.
