The recording medium delivery mechanism includes a slider, a holding lever, a biasing portion, a lever-opening operation portion, and a housing and discharging drive unit. The slider is supported on a chassis to be movable in housing and discharging directions of a recording medium. The holding lever is rotatably supported by the slider and configured to hold the recording medium. The biasing portion is configured to bias the holding lever toward the recording medium. The lever-opening operation portion is provided to the holding lever, is engaged with a lever engagement portion provided to the chassis by a movement of the slider in the discharging direction of the recording medium, and configured to rotate the holding lever in a direction away from the recording medium. The housing and discharging drive unit is configured to move the chassis and the slider in the housing and discharging directions of the recording medium.

Recording medium delivery mechanism and recording medium changer

A disc drive apparatus includes: an outer casing; a disc drive unit that includes a disc table on which a disc-like recording medium is mounted, a spindle motor, an optical pickup, and a pickup base; a slider that includes a main body and a rack gear, is movable in a first direction as an insertion direction and a second direction as an ejection direction, and moves in the second direction during loading and moved in the first direction during ejection; a drive motor functioning as a drive source of the slider; a deceleration gear group that intermeshes with the rack gear; an eject lever that is rotated to press the recording medium during the ejection; and a link member coupled with the eject lever, the slider including a lock plate and a slide plate.

Disc drive apparatus and electronic apparatus

A disk drive device includes: a rotary arm rotatable according to loading of a disk between a draw-in position and an eject position for ejecting the disk from a housing; a drive mechanism providing driving force for the rotary arm; a link arm mechanism interconnecting the rotary arm and the drive mechanism and rotating the rotary arm from an insertion position to the eject position when ejecting the disk; and a guide cam having a guide edge on which a guide projection of the link arm mechanism slides when ejecting the disk to rotate the rotary arm in an ejecting direction via the link arm mechanism, the guide projection moving around the guide cam from insertion to ejection of the disk. Engagement between the guide projection and the guide edge is released when a force opposite to a rotation direction is applied to the rotary arm when ejecting the disk.

Disk drive device

The present invention is directed to a disk drive apparatus in which an optical disk () is detachably loaded, and comprises a casing () including a front panel () in which a disk insertion/withdrawal hole () of which length in length direction is caused to be substantially the same as the diameter of the optical disk, and a biasing member () for biasing plural rotational arms (), () for holding the outer circumference of the optical disk therebetween in a predetermined direction in accordance with carrying position of the optical disk, wherein, between the disk insertion/withdrawal position and the disk loading position, there are provided a disk carrying mechanism () for performing carrying operation of the optical disk, a disk loading portion () to which the optical disk is loaded, a disk rotation drive mechanism () for optical disk, an optical pick-up () for performing recording and/or reproduction of information signals with respect to the optical disk, and a pick-up feed mechanism () for allowing the optical pick-up to undergo feed operation, wherein a slide contact piece () caused to be slidably in contact with the outer circumferential surface of the optical disk caused to undergo insertion/withdrawal operation with respect to the disk insertion/withdrawal hole is provided at one end portion in a length direction of the disk insertion/withdrawal hole to limit sudden movement of the optical disk.

Disk drive apparatus

A disc drive device which can discharge a disc in an optimum discharge amount in the disc drive device dealing with discs having different thickness and weight. A disc drive device including a disc conveying mechanism formed with a supporting portion to support the optical disc, and having a plurality of arms rotatably supported in the housing, and an energizing member for rotatably energizing the plurality of the rotary arms in a predetermined direction, and conveying the optical disc between a disc mounting position for holding the optical disc inserted into the housing in the disc holding portion and a disc insertion/removal position for inserting/removing the optical disc, the top cover having a control portion for controlling a rotary region of the plurality of rotary arms which energizes the optical disc in the discharging direction by contact with the plurality of rotary arms supporting the outer peripheral surface of the disc.

Disc drive device

An external storage device connected to electronic equipment through a cable includes a switch for selecting functions of the main unit of the external storage device. A user freely sets the function of the external storage device by simply operating the switch. This arrangement eliminates the need for disassembling the external storage device to switch the function thereof. The switch may be externally exposed out of the case of the external storage device.

External storage device and entertainment system incorporating the same

A vibration damping apparatus is provided with a main body, an elastic deformation section provided on the main body, and a projection which is made to follow the actions of the elastic deformation section and deform in every direction. The elastic deformation section acts as a damper to enable the vibration damping apparatus to dampen external vibrations transferred to the projection. For that reason, in recording/reproducing apparatus and other electronic apparatus on which the vibration damping apparatus is installed, it is possible to realize a reduction in the time needed to write to and read from a recording medium.

Vibration damping apparatus for damping external vibrations

A recording/reproducing apparatus including a door member having its upper edge abutted against a lower edge of a forward stationary plate. The lower end of the stationary plate and the upper edge of the door member are formed with inclined surfaces that are inclined relative to the direction of insertion and detachment of a recording medium. When the recording medium is inserted, the door member is rotated by having its inclined surface thrust by the forward edge of the recording medium so as to be separated from the forward stationary plate to open the front side of the cartridge holder holding the recording medium to prevent intrusion of dust and dirt into the inside of the apparatus.
