A recording medium drive device includes: a holding unit configured to hold a recording medium inserted from a slot; a link mechanism including a plurality of arms turnably connected to each other; an eject lever activated in response to the turning motions of the link mechanism for pushing the recording medium to eject the recording medium from the slot; a drive source configured to supply a drive force for the turning operations of the link mechanism; an urging spring disposed in the link mechanism for applying an urging force in the ejecting direction to the recording medium when the recording medium is inserted from the slot; and position regulating means disposed at a position to suppress the urging spring for the recording medium, for regulating the arms of the link mechanism at the ejecting time.

Disk transfer mechanism, and disk drive device

A disk drive device includes a device main body in which a disk slot for inserting and removing a disk-like recording medium is provided, a disk holding unit that rotatably holds the disk-like recording medium, a main chassis that supports the disk holding unit and a base unit, an arm unit rotatably supported on one or the other side in a plane parallel to the disk-like recording medium, an urging arm that urges the disk-like recording medium, a first centering member that supports the side of the disk-like recording medium, and a second centering member that supports the side of the disk-like recording medium. The first centering member and the second centering member are regulated in positions to support the side of the disk-like recording medium. The first centering member and the second centering member support the disk-like recording medium in a centering position.

Disk drive device and centering members therefor

Disclosed herein is a recording medium drive system including: a casing provided in a front face thereof with a slot through which to insert and discharge a recording medium having a principal surface and an opposite surface; and a sheet-formed member provided so as to close the slot and having a loop-formed deflected part which, while being deformed, is capable of making contact with at least one of the principal surface and the opposite surface of the recording medium at the times of insertion and discharge of the recording medium.

Recording medium drive system and electronic apparatus

A recording medium driving device which records information in or reproduces information from the recording medium, includes a device body in which a recording medium is inserted and from which the recording medium is removed, a conveying mechanism that conveys the recording medium in a loading direction and an eject direction, a mounting section on which the recording medium is mounted, a conveyance arm that moves according to movement of the recording medium in the loading direction and the eject direction and conveys the recording medium, and a driving mechanism that has a driving source for imparting a driving force for moving the conveyance arm. The conveyance arm includes a contact section that brought into contact with the recording medium and an urging member that urges the contact section in the eject direction of the recording medium.

Disk conveying apparatus

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 () is built into a tray () which can be extracted from and retracted into an external chassis () and moves a disk-shaped recording medium between the ejecting position and the recording-reproducing position. A pinion () comprises an output end of the drive section () and rolls on a rack () of a chucking slider () to self-propel the tray (). After the tray () completely moves to the recording-reproducing apparatus side, an output from the drive section () of the tray () is used to move the chucking slider () to the ejecting direction of the tray (). Then, a cam groove () provided on the chucking slider () is used to raise a base unit ().

Disc type recording/reproduction device

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 () is drawn into a recording and reproducing position by means of a tray (), a shutter opening and closing mechanism () arranged on the side of the apparatus is relatively moved with regard to the cartridge (). Thereby, shutter plates () of the cartridge () are opened or closed. Then, after the shutter plates () are completely released, the shutter opening and closing mechanism () is retracted by means of a cam () to be away from the cartridge ().

Disc type recording and/or reproducing apparatus

There are provided: detection sectionsfor detecting an edge of discsso as to be laterally symmetrical about a center, at a lower edge portion inside a long sideways openingof a front panel; and a detection sectionfor detecting a reflective foilhaving lack portionsput on a lower surface of a tray. If the disc is not in a regular mounting position in the tray, the disc may be prevented from falling to the inside of the drive by detecting the discsmounted in a misaligned state and discontinuing an operation of pulling the trayin, with the combination of detection outputs from those three detection sections.

Disk-type recording and/or reproducing apparatus and method of judging disc-shaped recording medium of disc-type recording and/or reproducing apparatus

Disc recording and/or reproduction apparatus

Disclosed is a disk recording and reproduction apparatus for recording and/or reproduction of optical disks of multiple different formats impossible to record or reproduce with a single pickup. A disk recording and reproduction apparatus containing a base unit () with two separate optical pickups () and () corresponding to two different format types and installed around the center of a turntable () for rotating a disk.
