AI Technical Summary

Problems solved by technology

[0009] However, in the future, in addition to the disc-shaped recording medium with a diameter of 8 cm or 12 cm, disc-shaped recording media with various diameters will be commercialized during the advancement of the recording density of the disc-shaped recording medium and the diversification of the recording medium. There is a high possibility that the above-mentioned conventional disk recording and / or reproducing apparatus cannot cope with such disk-shaped recording media having various diameters.

Embodiment Construction

[0046] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the embodiments described below, the present invention is applied to a disk reproducing device for reproducing information signals recorded on a disk-like recording medium such as an optical disk, and a disk loading mechanism provided with these.

[0047] The disk reproducing apparatus 1 is constituted by arranging necessary components and mechanisms in a casing 2, and the casing 2 has a front panel 3, a top panel 4, and a mechanical bottom panel 5 (refer to figure 1 as well as figure 2 ).

[0048] A laterally long disk insertion opening 3 a is formed on the front panel 3 .

[0049] The top panel 4 is formed in a flat plate shape, and the brake roller 6 is attached to the lower surface of the substantially central part.

[0050]The brake wheel 6 is configured by supporting the pulley 8 on the pulley supporting member 7 (refer to image 3 ).

Abstract

A disk loading apparatus includes first and second main gears (35, 43) disposed at equal distances to each other in radial directions from the center of rotation of a disk table (85) which is the center of rotation of a disk-type recording medium at an insertion completion position of the disk-type recording medium, and first and second feed rollers (38, 46) provided at positions on the first and second main gears (35, 43) displaced from the centers of rotation of the first and second main gears (35, 43) for rolling on an outer circumferential face of the disk-type recording medium (100). The disk loading apparatus further includes a driving mechanism for rotating the first and second main gears (35, 43) such that, when the disk-type recording medium (100) is to be moved toward the insertion completion position, the first and second feed rollers (38, 46) revolve on the first and second main gears (35, 43), respectively, while the first and second feed rollers (38, 46) roll on the outer circumferential face of the disk-type recording medium (100).

Description

technical field [0001] The present invention relates to a disk loading mechanism and a disk recording and / or reproducing device. Specifically, it relates to the technical field related to a disk loading mechanism for conveying a disk-shaped recording medium inserted from a disk insertion port to a mounting position for mounting on a disk table, and a disk recording and / or reproducing device equipped therewith. Background technique [0002] With respect to disk-shaped recording media such as optical disks, there are disk recording and / or reproducing devices capable of recording or reproducing information signals or both. For both disk-shaped recording media with a diameter of 8 cm and disk-shaped recording media with a diameter of 12 cm, There are devices that can perform recording and / or reproduction of information signals. [0003] In such a magnetic disk recording and / or reproducing apparatus, as a method of mounting a magnetic disk-shaped recording medium on a magnetic d...
