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.

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.

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).

Abstract: A disk drive apparatus includes a casing having an upper plate; and a tray. The upper plate includes an arm having an attracted member fixed thereto. When the tray moves from a protruding position to a recording-and-playback position, since engagements of the arm and the tray are engaged with each other, the main body of the arm swings, and the attracted member serves as a chucking position facing a chucked portion of the disk-shaped recording medium placed on the tray. When the tray moves from the recording-and-playback position to the protruding position, since the engagement of the arm is detached from the engagement of the tray, the main body of the arm swings, and the attracted member serves as a retracting position retracting above the chucked portion of the disk-shaped recording medium.
