Abstract

A suction type loading system which is compatible with CD of various sizes comprises an upper cover, a bottom case and an inside slip component having a compatible clamping piece. A housing which comprises the inside slip component is formed by connecting the upper cover and the bottom case by joint seal. As the heights of the upper cover and the side wall of the bottom case are different, a trough orbit is formed on the inner surface of the vertical side wall of the housing. The orbit is used for guiding the moving operation of the inside slip component which has a group of compatible clamping pieces that can judge the size of the CD inserted and clap the CD tightly in the moving process. When the CD inserted reaches a final read-write position, a lever mechanism is used for blocking off the faucet to avoid reinsertion during the read-write process.

Description

A kind of slot-in-type disk loading system that can compatible big small disc

Technical field

The present invention relates to use CD (for example, information storage medium such as CD and DVD) to carry out the CD-disc loading system of information record.The present invention be more particularly directed to have the slot-in-type disk loading system of compatible apparatus.

Background technology

Because CD has high-performance, the characteristics of digital storage, CD has become main data storage medium, and gos deep into day by day in people's the life.Existing having in the compatible CD-disc loading system with drive unit of CD, there are a kind of suction, the formula CD-disc loading system of spuing mainly to be used in the vehicle optical disk Play System.This slot-in-type disk loading system contains signaling switch and a snap ring.

After the user inserts the CD socket with CD, CD will touch the snap ring of socket inside and make snap ring adjust self size according to the disc size of inserting.The adjustment of snap ring is to finish by the spring of the CD extruding snap ring inside of different size.By this, reach the compatibility of CD-disc loading system.

After the insertion, CD at first triggers the signaling switch in the CD-disc loading system and makes motor starting.Motor is written into the optical disk reading player with CD and places it in the tram of read-write.Though the laser head of this CD-disc loading system can be fixed in normally the reading of data of fixing a point and guarantee, such CD-disc loading system complex structure.Especially, transmission mechanism comprises many parts.Because make the accuracy requirement height, cost of manufacture is higher.

Another shortcoming of this CD-disc loading system is that the spring of snap ring is according to the size of inserting CD and pressurized opens.CD is to be held up by left and right sides both direction.Because in order to clamp the CD of 80mm, when holding up the 120mm CD, CD can bear the very big pressure from snap ring, the result is that CD can be out of shape, and is destroyed, or makes bad read-write quality.

The another kind of existing CD-disc loading system that possesses compatible and drive unit is the CD-disc loading system with concentric structure of different levels.CD is to be written into suitable position by the disc box.Such CD-disc loading system is simple in structure.But, owing to need to use more than one disc box, and between CD and optical disk cartridge, need to leave certain clearance, with guarantee CD send into CD-disc loading system after CD can rotate stably, so optical disc apparatus will have suitable thickness.

In addition, for CD is held up make it and the disc box between form certain interval, just must be designed to mobilizable the connection, for example between spindle drive motor and the object lens with between fixture and the laser head block.The result is, is very difficult to shock-absorbing, and being difficult to shock-absorbing just directly influences the correctness that data of optical disk reads.What is more, after long-term the use, the aging and even fault when parts, this problem is just more serious.It is very big that the noise of CD-disc loading system can become.

Summary of the invention

In view of the above, the present invention proposes is a kind of slot-in-type disk loading system that can compatible various sizes CD.This new slot-in-type disk loading system is to be controlled at the various sizes of CD insertion back judgement CD with the CD of some, and by different transfer operations optical disk transfer is carried out reading and writing data to final appointed positions after this.

Fundamental purpose of the present invention is to propose a kind of compatible suction-type loading system, and this system architecture is fairly simple, and low to making accuracy requirement, cost of manufacture is lower, can not twist damaged compact disk, and good clamping effect.The housing of this compatible suction-type loading system comprises a socket, a pair of intermediate plate, a compatible apparatus and an interior saddle.CD control also is utilized to judge the CD of insertion.In case after the disc size that is inserted into was determined by CD control, the transfer operation corresponding with disc size also just was determined and is activated.

The transfer operation that compatible apparatus is used to judge the size that each is inserted into CD and determines to carry out.In the process that CD is transmitted, CD is clipped on the interior saddle tightly by intermediate plate.Have the wall groove on the housing wall, saddle is operated with the CD of guaranteeing to insert with guide rod and is sent into final appointed positions reposefully in making, carries out high-quality reading and writing data.

In enclosure interior, the appropriate location, bottom of loading system is provided with projection.On compatible apparatus and intermediate plate, be provided with and separate projection.In final appointed positions, separate projection and will be held up and make CD to separate by projection with interior saddle.

Use a kind of platen device of similar cap profile among the present invention.The last bossing of similar hat-shaped just can be embedded in the hole that the housing top cover has.When transfer operation began, the platen device was limited on the rotating disk of CD above interior saddle and because cap shape bossing is embedded in the hole.In the transfer operation process, the platen device at first is to be still on the interior saddle, is passed to the CD top of insertion then.When CD arrives final appointed positions, intermediate plate can open and discharge CD.The platen device of CD and its top will fall on the rotating disk of laser head.The platen device is tightly pushed down CD.High-quality reading and writing data can thereby be finished.

To such an extent as to second purpose of the present invention is that the structure of further simplifying loading system further reduces cost of products.In order to obtain this target, this new suction-type loading system has reduced the needed part of compatible various sizes CD, the clamping effect when having improved operation simultaneously.

The end box that the housing of compatible suction-type loading system closely links together by top cover, with top cover is now formed.The front end that can supply the socket of CD turnover at housing.Compatible apparatus and intermediate plate are configured to a subassembly, can judge CD size and can be with on the saddle in the CD that inserts being clipped in tightly.Therefore, only need to use one group of magnetic patch and iron plate two groups of magnetic patch and the iron plate before replacing, just can prevent compatible intermediate plate disengaging.Interior saddle places enclosure interior to be used to pinch CD to read and write position.

Two groups of CD controls have replaced three original CDs to control the size of judging CD.First group of control be being used to judge little disc of series connection and second group of control be series connection be used to judge big disc.This first group is in parallel with second group of control.

The side of interior saddle is provided with the guide pillar of some to guarantee to transmit stably CD.Especially, the inside surface of case side wall is provided with the fluted body track, the wall groove before having substituted.When top cover and end lid together, just formed the housing of saddle in inner having.Interior saddle moves to the housing rear end near housing front end socket along track with this grooved tracks of the guide pillar insertion inner walls of its some.

The shape of track also has improvement.Make CD to separate at the formed falling ramp of track end, also make CD can take out later in the read-write of laser head rotating disk with interior saddle.End prolongation at falling ramp has the one section very short track parallel with grooved tracks.That is to say that track is manufactured into the shape of " Z ".The parallel short track of this falling ramp end can give certain initial power when getting the dish operation, make the taking-up operation easier.

In the final position of discs, projection is used to hold up explant, and the insertion CD is separated with interior saddle.The lower lock block of interior saddle below is depressed the lever that leans on the projection limit, makes that the piece baffle in the socket rear end is held up and block socket to prevent the insertion again of CD.

This research and development recently and improved pattern have reduced the cost of manufacture and the manufacturing course of suction-type loading system significantly.This compatible suction-type loading system neither need be provided with the wall groove on sidewall, the intermediate plate that does not also need to separate cooperates with compatible apparatus.Therefore, reduced the volume of loading system and improved efficient greatly.Most importantly, use two groups of CDs to control and judge that inserting disc size is reasonable design, both use can also prevent possible misjudgment easily.Especially, they can be revised easily to adapt to the size of following different discs.

The present invention has done further development and improvement to the slot-in-type disk loading system.A specific embodiment is illustrated among Fig. 6.With reference to figure 6, specific embodiment shown in it comprises that 600, one of a rectangle loam cake that have a stepped ramp type sidewall 604 has interior saddle 609 and an end box 616 that has worm and wormwheel 615, projection 617 and motor 614 of compatible intermediate plate.Loam cake 600 and end box 616 are closely together the housing of forming loading system.On connect lug 603 with under connect lug 612 and be connected by screw.These lugs 603,612 can be further by screw tightening and be fixed on the other system parts to produce computing machine, CD Player, perhaps other CD register systems.

Have a hole 601 on the loam cake 600, its function is equivalent to a restraint device and allows to insert in the cap shape projection insertion hole of disc folder 608.Restriction hole 601 has a downward becate, is limiting CD rotating disk 621 tops that disc folder 608 is still in laser head, and the disc above the saddle 609 presss from both sides on the pallet in resting on when idle condition.When a CD is inserted into, interior saddle 609 beginnings are moved to the rear away from socket.The same time, the CD of insertion has replaced interior saddle 609 at leisure and has become below disc folder 608.After interior saddle arrived sink node, CD was discharged by interior saddle 609.Disc folder 608 can be fallen on the CD rotating disk of laser head in the lump with the CD that inserts and tightly CD is pressed on the CD rotating disk 621.

On the stepped ramp type sidewall 604 of loam cake 600, leave opening 602 and allow the attaching plug 611 of outside equipment be connected with it.Because the height of the stepped ramp type sidewall of loam cake 600 is greater than the height of end box 616 sidewalls 613, the inside surface of the sidewall 604 of loading system can form the track 618 of similar groove after housing forms, and the height of track 618 equals the difference in height of loam cake 600 sidewalls and end box 616 sidewalls 613.Specifically, long and can link closely and encase the sidewall 613 of relatively short and more narrow end box 616 than loam cake 600 sidewalls of broad.Recessed together being pickled with grains or in wine just forms with the stepped ramp type of loam cake 600 is regional on the sidewall 613 of end box 616.Some solidify nose bars 624 and are established on the end box sidewall 613 fastness with box 616 at the bottom of the further reinforcement.One recessed 605 inside surface at stepped ramp type sidewall 604 that the outside surface of stepped ramp type sidewall 604 forms just formed a convex surface.This concave surface 605 is that design keeps manufacturing purpose that loam cake 600 thickness can uniformity.

Being provided with two pairs on the sidewall of interior saddle 609 leads protruding.The a pair of of front end leads protruding 606 greater than leading of rear end protruding 607.Laser head with framework 619 is assemblied in the bottom of end box 616 with some shockproof screws 622.CD rotating disk 621 is positioned near the front end dust excluding plate 625 of end box 616.Be provided with projection 617 near the worm and wormwheel 615, the separation projection of saddle 609 belows in holding up with it with certain angle inclined-plane 620.A shutdown switch 623 is installed on the rear wall of end box 616.When interior saddle 609 arrival final positions, just, the rear wall of end box, interior saddle 609 will be opened shutdown switch 623 and stop transfer operation.Certainly, laser head also can be installed in another way and carry out reading and writing data above CD.

The interior saddle 609 that is provided with compatible intermediate plate 702 can be described in more detail by Fig. 7.The top of saddle 609 in two intermediate plates 702 are fixed on.Two blocks of magnet 705 is embedded in the aperture near compatible intermediate plate 702 front ends of socket.In the bottom surface of compatible intermediate plate, the iron plate 706 of saddle 609 upper surfaces attracted in magnet 705 can appear and be positioned at.Two are separated the bottom surface that projection 707 is arranged on intermediate plate 702.When interior saddle 609 moved, iron plate 706 was attracted each other with magnet 705 and will be inserted CD tightly and clamp.The centre position of interior saddle 609 has one relative to circular part and the rectangle fluting 704 that can supply laser head to move.CD storage tank 708 with respect to maximum disc size forms to prop up CD at the front end of interior saddle 609.The disc in the centre position of saddle folder pallet 703 is a little more than optical disc tray 708 in being arranged on, and disc folder 608 stays in here when idle state.

Saddle 609 belows were in order to transfer operation in tooth bar 712 was installed in.In the bottom surface of compatible intermediate plate 702, two little CD controls 710 are mounted respectively in the edge near fluting 704.These little CD controls 710 are connected on can judge the size of inserting CD together.If a control only is installed, big disk plate also can touch because of unbalanced insertion and active controller.Therefore, adopted a pair of CD control.

Separate the outward flange that projection 707 is installed in compatible intermediate plate 702, when interior saddle 609 transmits CDs and arrives final appointed positions in order to saddle the separation in 609 and the CD that is transmitted.Corresponding on the inclined-plane 720 that separates projection 707 tops with 620 angles of inclination, inclined-plane on the projection 617.In addition, a pair of arc back-up ring 718 that has guiding surface 719 is installed in compatible intermediate plate 702 foremost.The function class of arc back-up ring 718 like the CD storage tank in order to prop up the small disc that inserts loading system.

But, when a big disk plate enters loading system, CD at first touches the guiding surface 719 on compatible intermediate plate 702 tops.In case guiding surface 719 has been touched by big disk plate, compatible intermediate plate 702 will be held up.Big disk plate has just slipped under the compatible intermediate plate 702 and has stayed on the CD storage tank 708 of interior saddle 609.CD storage tank 708 is more lower slightly than disc folder pallet 703 on interior saddle 609.CD storage tank 708 is equivalent to a storage tank and a stop means.

The structure of saddle 609 and compatible intermediate plate 702 in Fig. 8 can further show.Compatible intermediate plate 702 is fixed on the interior saddle 609 by project planning 802.This compatible intermediate plate 702 can be opened and close in the enclosure interior space.Magnetic patch 705 and corresponding with it iron plate 706 are used to provide the effect of disc folder.The going up table of saddle 609 in one group big CD control 801 is installed in and, when big disk plate is inserted into, be used for judging the size of big disk plate.There are one group of hole, 804 corresponding stop means 803 to be provided with.Stop means 803 is to be used for preventing that CD from exceedingly firmly being injected deeply interior saddle 609 and touching big CD control 801.

When a small disc is inserted into, the little CD control 710 of compatible intermediate plate 702 front ends can at first be touched.The arc back-up ring 718 of compatible intermediate plate 702 will be held small disc and start the transfer operation of little CD.In other words, arc ring washer 718 also will limit the part that little CD rests on optical disc tray 708.After small disc arrived final appointed positions, projection 617 holds up separation projection 707 made compatible intermediate plate 702 open, and discharges small disc from interior saddle.Disc folder 608 can and small disc falls and CD is clipped on the CD rotating disk 621 tightly.Data read-write operation begins.The present invention uses one group little CD control to activate with the mistake that prevents to cause owing to the unbalanced insertion of big disk plate.

When a big disk plate is inserted into, to such an extent as to because the diameter of CD can not touch little CD control 710 too greatly.The substitute is, big disk plate can touch the guiding surface 719 that is installed in compatible intermediate plate 702 most advanced and sophisticated arc back-up rings 718 and hold up compatible intermediate plate 702.The CD that inserts enters between interior saddle 609 and the compatible intermediate plate 702.Be positioned near the big CD that rectangle slots 704 inward flanges and control 801 places so big disk plate further inserts and reaches.Then, big CD transfer operation is activated.

Fig. 8 has showed the vertical view of loading system.A CD inserts the interior saddle 609 of socket 807 activation and moves.Lead protruding 606,607 be arranged in the both sides of saddle 609.Leading protruding 606,607 is inserted in by loam cake 600 and links closely in the end box 616 formed tracks 618.When interior saddle 609 when move the rear end of loading system, short-range missile protruding 607 can be by by the formed halt 605 of loam cake 600 outer surface grooves.But length is led protruding 606 and can not be passed through halt 605.When short-range missile protruding 607 arrives tracks 618 ends, the projection 617 on the end box 616 will contact and hold up and separate projection 707, and compatible by this intermediate plate 702 will be opened and discharge and be sandwiched in inner CD.Subsequently, interior saddle 609 glides along the inclined-plane of track 618 ends and drops to the position that is lower than CD rotating disk 621.

Meanwhile, with reference to figure 9, a bar handle end 902 of the lower lock block 906 compressing levers below interior saddle 609 descends it, and forces to be positioned near socket 807 another bar handles of lever and rise, and by this, holds up catch 903 and blocks socket 807.Fig. 9 has showed two sectional views of the specific embodiment of the invention.Leverage is equipped with that pivot shaft 901, one bar handles terminal 902 tilt to be fixed against projection 617 and another bar handle extends to the catch 903 that is in socket 807 belows.When lower lock block 906 was depressed lever bar handle 902, catch 903 will rise and block socket 807 and prevent to insert CD again.

Fig. 9 shows the sectional view of the track 618 that is formed on stepped ramp type sidewall 604 inside surfaces.At idle state, interior saddle 609 is still near the last front end socket 807 of loading system.A bracing or strutting arrangement 900 is arranged on the sidewall of end box 61 6, in order to saddle 609 in supporting.When interior saddle 609 has just begun to move along track 618, short-range missile protruding 607 is because little of halt 605, and saddle 609 was in order to avoid it slips into first inclined-plane 904 in bracing or strutting arrangement 900 supported therewith.Interior saddle 609 will continue to move.
