TW448420B - Device for vertically loading compact disk - Google Patents

Abstract

A device for vertically loading compact disk is applied to a CD drive capable of being used vertically and horizontally. An elastic member, a first loading sheet, a second loading sheet are formed on one side of the tray of the CD drive which is a bottom when vertically arranged, so as to prevent the CD from turning over. A protrusion block on the loading mechanism base is employed together to drive the first loading sheet to enable the CD to normally rotate when the tray is turned back. As a result, the CD drive can be used for vertically loading and achieves the same effect as that for horizontally loading in the conventional skill.

Description

448420 V. Description of the invention (1) [Scope of application of the invention] The present invention relates to a device for an optical disc drive, and in particular to a carrying device that makes the optical disc drive suitable for upright use. [Related technology] In the peripheral products of personal computers, optical disc drives have become an indispensable device. Recently, multimedia information is popular. Many data and products are stored on optical discs. In addition, the data stored on optical discs are stored. It has its advantages, so the demand and popularization of CD and DVD optical disc drives have been increasing. However, the conventional optical disc drive is usually designed to carry horizontal discs when carrying optical discs, and it does not take into account the application of upright discs, or the need to reserve space for the upright discs 2 a, 2 b and the held discs. The pushing mechanism (as shown in "Fig. 1"), or the upright carrier sheets 3a, 3b, 3c '3d need to be raised > high (as shown in "Fig. 2") when the optical disc is read. In the Republic of China Patent Bulletin No. 3 3 6 7 6 6 for the upright bearing device of the optical disc drive, the three positions of the first supporting disc are used to achieve the horizontal and vertical positioning of the optical disc drive. The function of the optical disc and the release of the optical disc, in the state of being placed upright: 1. When the tray (Tray) is pulled out, the first carrier sheet is rotated to hold the optical disc due to the restoration torque of the torsion spring. Position to prevent the disc from turning out: 2. When the tray is pushed in, the protruding point of the first carrier sheet is pushed to rotate, so that the first carrier sheet is rotated to the position where the disc can be released, so that the disc has enough space for reading. action. However, due to the large thickness space required for the upright bearing device, the height of the holding piece relative to the tray is relatively high, and since the first holding piece is required to rotate by using the protrusion of the holding piece, the area required for the holding piece is too τ and Increase parts into

448 V. Description of the invention (2) Ben 0 The first bearing sheet of the present invention does not have a protruding short column of a second-order plane, which can reduce the thickness of the first bearing sheet and reduce the thickness of the holding sheet; The driver who pushes the first carrier sheet in the middle is the base of the carrier mechanism, and does not rely on the protrusion of the anchor sheet. Therefore, the anchor sheet can reduce the area, which can reduce the cost of parts. [Objective and Summary of the Invention] The main object of the present invention is to provide an upright carrying device for optical disc drives, which can be applied to optical disc trays for horizontal and vertical use of optical disc drives. In the conventional tray design, The simplified upright carrying device is used to overcome the shortcomings of conventional optical disc drives that cannot be placed upright, or to reduce the gap between the holding piece and the tray, reduce the thickness of the optical disc drive bearing mechanism, and increase the application space of the entire set of optical disc drive mechanisms and circuits , And reduce the area of the holding sheet, and reduce material costs. The upright carrying device of the optical disc drive disclosed in the present invention prevents the optical disc carried by the optical disc drive from falling down when it is in an upright position, and includes: a tray having a circular groove in the center for placing a large optical disc, and When the optical disc drive is upright, it is a circular groove edge at the bottom, forming a first groove and a second groove. In the first groove, an elastic member is used to block the gall, a screw post, and a hook. A protrusion is formed on the top; a second screw post and-^ hook are formed in the second groove, and a protrusion is also formed on the hook; a first carrier sheet is assembled in the first groove of the tray, There is a round hole in the center, which is assembled to the first screw post of the tray by a screw
