A disc drive apparatus is adapted to be driven when incorporated into a host appliance provided with a see-through section and comprises a disc receiving section for receiving a disc-shaped recording medium, a disc rotary drive mechanism for driving the disc-shaped recording medium to rotate, a recording and/or reproduction mechanism for recording information signals on and/or reproducing information signals from the disc-shaped recording medium and an apparatus main body arranged in correspondence to the see-through section formed in the host appliance and provided with a see-through hole exposing part of the disc-shaped recording medium placed on the disc receiving section to the outside of the host appliance by way of the see-through section.

Disc drive apparatus and electronic appliance

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

A disc drive apparatus comprises a housing; a disc-holding unit that holds an optical disc in the housing; a disc-driving mechanism that rotates the optical disc held by the disc-holding unit; an optical pickup that writes signals in, and reads signals from, the optical disc being rotated by the disc-driving mechanism; and a pickup-moving mechanism that moves the optical pickup in a radial direction of the optical disc. The housing has an air-inlet port which is located above the optical disc held by the disc-holding unit and through which air is drawn from outside by virtue of an airflow that develops as the optical disc is rotated, and air-outlet ports through which air is discharged from the housing.
