  • Publication number: 20220161563
    Abstract: A recording apparatus includes a recording head having an ejection port surface and a step portion, a blade to wipe the ejection port surface, and a moving unit. A plurality of ink ejection ports is arranged on the ejection port surface. The moving unit performs relative movement of the blade and the recording head by moving the blade or the recording head in a first direction to cause the blade to wipe a wiped surface including the ejection port surface, from the step portion to an area in which the plurality of ink ejection ports is arranged. The moving unit performs the relative movement so that a first relative velocity of the relative movement when the blade passes the step portion is higher than a second relative velocity of the relative movement when the blade, that has been in contact with the wiped surface, is separated from the wiped surface.

  • Publication number: 20180056221
    Abstract: In a filter device, a disc-shaped filter is disposed on a main flow channel through which a gas flows, and the filter is rotated by a motor. A branch flow channel branches off at the downstream of the filter in the main flow channel, and branched gas is passed through the filter in an opposite direction. Rotation of the filter moves dust collected in a dust gathering region where the filter and the main flow channel overlap with each other to a cleaning region where the filter and the branch flow channel overlap with each other so that the dust is disengaged from the filter. Thus, the filter of the filter device can be automatically cleaned.

  • Patent number: 7370338
    Abstract: A disk recording-reproducing apparatus ensures a large transport distance of a tray which moves a disk-shaped recording medium between an ejecting position and a recording-reproducing position while decreasing a dimension in the transport direction. A drive section (47) is built into a tray (13) which can be extracted from and retracted into an external chassis (10) and moves a disk-shaped recording medium between the ejecting position and the recording-reproducing position. A pinion (56) comprises an output end of the drive section (47) and rolls on a rack (24) of a chucking slider (20) to self-propel the tray (13). After the tray (13) completely moves to the recording-reproducing apparatus side, an output from the drive section (47) of the tray (13) is used to move the chucking slider (20) to the ejecting direction of the tray (13). Then, a cam groove (23) provided on the chucking slider (20) is used to raise a base unit (30).

  • Patent number: 7269834
    Abstract: A disc type recording and/or reproducing apparatus automatically performs the opening and closing of a shutter provided on a cartridge housing an optical disc in its case, and prevents the above-mentioned opening and closing mechanism from affecting the cartridge after an end of loading. When a DVR cartridge (51) is drawn into a recording and reproducing position by means of a tray (13), a shutter opening and closing mechanism (65) arranged on the side of the apparatus is relatively moved with regard to the cartridge (51). Thereby, shutter plates (100) of the cartridge (51) are opened or closed. Then, after the shutter plates (100) are completely released, the shutter opening and closing mechanism (65) is retracted by means of a cam (85) to be away from the cartridge (51).

  • Publication number: 20070169135
    Abstract: A disk drive device includes a housing provided with a disk slot in which a large-diameter disk-like recording medium is inserted and from which the recording medium is ejected, an eject arm that ejects the large-diameter disk-like recording medium, and a disk conveying mechanism that rotationally moves at least the eject arm to an ejection position of the large-diameter disk-like recording medium. The eject arm is provided with a stopper that prevents insertion of a small-diameter disk-like recording medium. When the eject arm is rotationally moved to the ejection position, the stopper is rotationally moved to a position where the stopper is brought into contact with a side on an insertion end side of the small-diameter disk-like recording medium when substantially the entire small-diameter disk-like recording medium is inserted from the disk slot.
