Abstract

The invention provides a protective cover for an optical drive core part. An actuating groove is arranged upwards on the protective cover; a round hole is arranged on one end of the actuating groove; a long hole extends from the periphery of the round hole to the other end of the actuating groove and forms a bind, and further extends to form an extended end with a shape of platform; the extended end nears lower end of the opening of the suction optical drive and is tilted an angle from the opening to the inner side of the suction optical drive; and the tilt angle is towards the connecting piece end of the positioning rod to avoid blocking an optical disk.

Description

CD ROM mechanism protective cover

Technical field

The relevant a kind of CD-ROM drive of the present invention especially about movement in the absorbing optical drive, inserts the movement over cap of CD-ROM drive direction in order to the direct light disc.

Background technology

General absorbing optical drive is after with manpower discs being inserted CD-ROM drive, to utilize the several backstays in the CD-ROM drive, drives discs automatically and arrives play position.Because there are many spaces in backstay mobile, therefore, correctly inserts the direction of discs, allows discs not snap in the space, with suitable contact backstay, for the decision backstay accurately the guide lights disc to the key factor of locating.

As shown in Figure 1, be the action synoptic diagram that a traditional absorbing optical drive 10 inserts discs 11.In the casing 12 of tradition absorbing optical drive 10; has the movement 13 that moves up and down; movement 13 1 ends are provided with a spindle motor 14; movement 13 also has an over cap 15; over cap 15 front ends are provided with an elongated end 16; be positioned near 18 inboards, CD-ROM drive 10 gateways; make the discs 11 of insertion; the tab end that suitable its direction is stretched to backstay 17; and promote backstay 17 to touch sensor (figure does not show), start absorbing optical drive 10, drive backstay 17 with its tab end direct light disc 11 to spindle motor 14 location; by spindle motor 14 rotating disc sheets 11, with the data of writable disc sheet 11.

Yet; the elongated end 16 of over cap 15 front ends is a horizontality; when not inserting discs 11; be with the movement 13 lower position in casing 12 that descends; be positioned at the downside of gateway 18 approximately; to vacate the channel that discs 11 enters absorbing optical drive 10; thereby when discs 11 downward-sloping insertion gateways 18; to make discs 11 front ends stretch into the below of backstay 17 tab end, and be stuck in backstay 17 lower edges, not only cause discs 11 scratches easily; and can't correctly promote backstay 17; automatically drive discs 11 to the location to start absorbing optical drive 10, even touch other member, cause absorbing optical drive 10 misoperations and stuck.Therefore, traditional absorbing optical drive 10 is textural, and it is to be solved to still have problem to have.

Summary of the invention

The object of the present invention is to provide a kind of CD ROM mechanism protective cover, by the angle of movement over cap elongated end that is inclined upwardly, the angle that the direct light disc inserts is avoided the jam discs, to improve the fiduciary level of start.

In order to reach the purpose of aforementioned invention; CD ROM mechanism protective cover of the present invention; cover the movement of absorbing optical drive; over cap upwards digs along spindle motor shaft and establishes a start groove; this action groove one end is a circular hole, and the other end is a strip hole, and strip hole is extended to this other end of start groove by the periphery of circular hole; end in the close CD-ROM drive gateway of start groove forms a bending, extends the elongated end that constitutes a platform-like again.Elongated end is near the lower side of absorbing optical drive gateway, and by the gateway to the inboard that the sucks CD-ROM drive angle that tilts, the angle of inclination is towards the tab end of backstay.

Embodiment

Relevant the present invention is for reaching above-mentioned purpose, and technological means that is adopted and effect thereof are now lifted preferred embodiment, and conjunction with figs. is illustrated as follows.

Please refer to Fig. 2, be CD-ROM drive movement 20 of the present invention, comprise a body 21, over cap 22, spindle motor 23 and optical read head 24.Wherein, body 21 is a polygon bluff body framework, disperses that on every side several are set and keeps away the damper 211 that shakes.Over cap 22 is a flat board; be covered in body 21 above; over cap 22 upwards digs along the CD-ROM drive motor shaft and establishes a start groove 221; one end of start groove 221 is a circular hole 222; the other end of start groove 221 is a strip hole 223, and strip hole 223 is extended to this other end of start groove 221 by the periphery of circular hole 222.Over cap 22 forms a bending 224 in that start groove 221 is terminal, connects or extends the elongated end 225 that constitutes a platform-like, elongated end 225 and towards the downward-sloping angle θ (please refer to Fig. 3) of end.Spindle motor 23 is installed in the circular hole 222, and in order to rotate a discs 25 (please refer to Fig. 3), optical read head 24 then is located in the strip hole 223, and can slidably reciprocate along strip hole 223.

As shown in Figure 3, make cardon for the suction CD-ROM drive 30 of installing CD-ROM drive movement 20 of the present invention.This suction CD-ROM drive 30 comprises the backstay 32 of a gateway 31 and direct light disc 25.CD-ROM drive movement 20 is located at and is sucked in the CD-ROM drive 30, elongated end 225 makes the elongated end 225 of a downward-sloping angle θ near the lower side of gateway 31, is raise gradually to the inboard that sucks CD-ROM drive 30 by gateway 31, and the angle θ of its inclination just may extend to tab end 33.In addition, spindle motor 23 is positioned at and sucks inboard of CD-ROM drive 30.Backstay 32 is by the rear side that sucks CD-ROM drive 30, and gateway 31 is stretched to its tab end 33 in the top of crossing spindle motor 23.

When discs 25 is inserted the gateway 31 that sucks CD-ROM drive 30; discs 25 front ends are with the guiding of protected lid 22 elongated ends 225; elongated end 225 along over cap 22 inclinations one angle θ; insert in the suction CD-ROM drive 30 with acclivitous direction; make discs 25 front ends directly shift to the tab end 33 of backstay 32, contact tab end 33, and be subjected to backstay 32 guiding; enter and suck CD-ROM drive 30, make discs 25 reach the location.

Therefore; CD ROM mechanism protective cover of the present invention; by inclination movement over cap elongated end; make elongated end by the gateway towards sucking the CD-ROM drive rear side; an angle θ is inclined upwardly; allow the oblique backstay in elongated end dip plane; angle with the insertion of direct light disc; allow the front end of discs shift to the tab end of backstay along the elongated end dip plane, avoid inserting lower edge, and can prevent that discs is by the tab end scratch to tab end 33; also can guarantee simultaneously the front-end edge of discs; shift to tab end, accept the location that guides to of backstay, to improve the fiduciary level of start.

Though; the embodiment of the invention with over cap and movement be dividing member as an illustration; so be familiar with CD-ROM drive technical field person; by previous embodiment, also can expect that over cap and movement can form integral member, maybe the elongated end that tilts is separated with over cap; be separately fixed on the movement; or directly elongated end is formed on the movement, all can reach purpose of the present invention and effect, all belong to technology category of the present invention.

The above person, only in order to convenient explanation the preferred embodiments of the present invention, scope of the present invention is not limited to these preferred embodiments, and is all according to any change that the present invention did, and not breaking away under the spirit of the present invention, all belongs to scope of the present invention.
