Embodiment Construction

[0041] Preferred embodiments of the present invention will be described with reference to the accompanying drawings. A disc recording and / or reproducing apparatus described in the following preferred embodiments is a portable reproducing apparatus for reproducing signals recorded on a high-density disc used as a disc.

[0042] Reference numeral 1 generally denotes a disc recording and / or reproducing apparatus according to a preferred embodiment of the present invention. The disc recording and / or reproducing apparatus has a housing 2 in which various required components and mechanisms are provided (see figure 1 to 3).

[0043] The housing 2 is usually formed by engaging an upper part 3 and a lower part 4 together. The outer shape of the housing 2 is substantially circular and flat. The housing 2 has a front surface formed with a disk insertion / ejection groove 2a, with figure 1 The side surface of the slide handle 5 that is slidable in opposite directions is depicted by the ...

Abstract

A disk recording and / or reproducing device capable of recording data onto a disk and / or reproducing data recorded on the disk, includes a disk mounting portion for mounting the disk; a chucking portion for chucking the disk in cooperation with the disk mounting portion, the chucking portion having a disk engaging portion for engaging the disk at the start of disk loading; and a slider for supporting the chucking portion and moving the chucking portion in a radial direction of the disk between a chucking position where the disk is allowed to be chucked and a loading position where the disk loading is allowed to be started. With this arrangement, the device can be reduced in thickness.

Description

technical field [0001] The present invention relates to a disc recording and / or reproducing apparatus, a disc loading mechanism and a disc ejecting mechanism, and more particularly to a disc recording and / or reproducing apparatus for disc recording and / or reproducing signals, a disc loading mechanism for loading a disc onto a mounting portion mechanism and a disc ejection mechanism that ejects a disc mounted on the disc mounting portion. Background technique [0002] Disc recording and / or reproducing apparatuses are conventionally known that are capable of recording or reproducing signals with respect to a disc, or recording and reproducing signals. [0003] Such a known disk recording and / or reproducing apparatus generally includes a disk table adapted to be rotated by a driving force of a spindle motor and a clamping plate relative to the disk table. When a disc having a central hole is inserted from a disc insertion / ejection slot formed through a ...
