As shown in figure 24, lower house 11 comprises chuck opening 11c and magnetic head opening 11h.Chuck opening 11c makes chuck spare (spindle motor that for example, is used for rotating disc 100) enter tray salver 308 from the outside.Magnetic head opening 11h make from/read and/or the magnetic head of write signal enters tray salver 308 and arrives the target location at dish 100 at dish 100 signal record side 100A.Lower house 11 is in the face of the signal record side 100A of dish 100.In addition, magnetic head opening 11h arrives the side of lower house 11.
Upper shell 12 comprises that dish 100 can enter and shift out and extend to expose the circular discs window 12w that coils 100 upsides at the whole raised zones that coils 100 from tray salver 308.Upper and lower casing 12,11 is bonding or weld together on its excircle, thereby forms box body 10.
The dish storage compartment 10d that is used for storage disks 100 therein limits by the interior lower surface 11u and the inner surface 12i of box body 10.Interior lower surface 11u is relative with dish 100 signal record side 100A, and the rounded substantially shape of inner surface 12i and being limited in the dish window 12w.That is to say that interior lower surface 11u is the bottom of dish storage compartment 10d.
In dish storage compartment 10d, width enough can make dish 100 gaps that rotate freely be arranged on inner surface 12i and coil between 100 the excircle.In addition, inner surface 12I is enough high, is stored in the dish storage compartment 10d so that coil 100 whens rotation whole dishes 100.The top of dish storage compartment 10d is dish window 12w, and the dish 100 that is stored in dish storage compartment 10d like this has an one side and exposes in dish window 12w.
Two movably coil block 23 and are provided for upper shell 12, so that in the local dish window 12w that protrudes shown in Figure 23 and 24.The 3rd dish block 12s is provided for upper shell 12, advances to coil window 12w so that protrude.But the 3rd dish block 12s forms the global facility of upper shell 12.The circumference of these three dishes block 23 and the basic drum window of 12s 12w are provided with even interval, fall down from coiling window 12w at valve 21,22 open periods and valve 21,22 periods of contact to prevent to coil 100.When this tray salver 308 was put in the disk drive of vertical fixing, these dish blocks 23 and 12s were effective especially.
Valve 21,22 is arranged between the interior lower surface 11u of dish 100 signal record side 100A and box body 10. Valve 21,22 comprises axis hole 21u, 22u respectively.These axis holes 21u, 22u match with an axle 11s at the state that rotates freely, and described axle 11s is positioned at the dish storage compartment 10d outside of box body 10 and relatively on the dark side of the box body 10 of its magnetic head opening 11h.Like this, valve 21,22 rotates on axle 11s, so that cover or expose chuck and magnetic head opening 11c and 11h.
Cam 21c and engaged wheel 22c are arranged at the axis hole 21u near valve 21,22, the position of 22u respectively.Cam 21c and engaged wheel 22c have the shape that is engaged with each other and constitute the 20c of interlock mechanism that is used to open with closure flap 21,22 together when it are interlocked each other.
The upper surface separately of the valve 21,22 relative with dish storage compartment 10d is coated with and is used to prevent to coil protective layer 21p and the 22p that 100 signal record side 100A is swiped or attracts dust.
Protective layer 21p and 22p can choose suitable material from the group that anti-scratch non-woven fibre, dustproof non-woven fibre, anti-scratch coating and dustproof coating are formed.In this preferred implementation, can the thin plate of the non-woven fibre that prevents dust is bonding respectively or be ultrasonically bonded to valve 21,22 as protective layer 21p and 22p.
Shutter spring 31,32 is separately positioned on the outside of the dish storage compartment 10d that is used for valve 21,22.These springs 31,32 are applied to valve 21,22 with elastic force and with this direction closure flap 21,22.In addition, also can elastic force be applied to valve 21,22 along this direction from the elastic component of any other form.
In tray salver 308 as shown in figure 24, each all comprises two dish folder 21a, 21b and 22a, 22b valve 21,22 at its two ends.Each of these dishes folder 21a, 21b and 22a, 22b all has the cross sectional shape (or inclination) to inferior pyramidal, and clamps the outward flange of dish 100 when valve 21,22 closures.Structure and the operation of dish folder 21a, 21b and 22a, 22b also will be explained below.
As shown in figure 23, the upper surface of box body 10 (or upper shell 12) have the user thereon indicator 100 stored contents label plane 10f and represent that this tray salver 308 should inject embossing arrow mark (or recess) the 10a indicated direction (arrow 1A) of disk drive direction.Box body 10 also is included in two recess 10c that are parallel on two side surfaces that inject tray salver 308 direction 1A.When tray salver 308 advances or puts into disk drive or when tray salver 308 is stored in the disc changer, these recesses 10c both can be as advancing recess also can be used as detent.
Figure 25 shows to remove upper shell 12 and coil 100 to show that its valve 21,22 covers the skeleton view of the tray salver 308 of chuck and magnetic head opening 11c and 11h state.In Figure 25, the dish of valve 21,22 folder 21a, 21b, 22a, 22b are positioned to clamp the outward flange (not shown in Figure 25) of dish 100.
Figure 26 shows to remove upper shell 12 and coil 100 to show that valve 21,22 exposes the skeleton view of the tray salver 308 of chuck and magnetic head opening 11c and 11h state.As the result that valve 21,22 rotates on its axis hole 21u and 22u respectively, chuck and magnetic head opening 11c and 11h are exposed now.In addition, when valve 21,22 rotations, dish folder 21a, 21b, 22a, 22b also rotate on axis hole 21u, 22u.As a result, dish folder 21a, 21b, 22a, 22b separate (not shown in Figure 26) with the outward flange of dish 100.
Figure 27 is that display panel 100 does not have fixing and shows that valve 21,22 covers the skeleton view of the tray salver 308 of chuck and magnetic head opening 11c and 11h state.As shown in figure 27, dish folder 21a, 21b, 22a, 22b protrude into dish storage compartment 10d.Therefore, when dish 100 was stored in this tray salver 308, dish 100 was clamped by these dish folders 21a, 21b, 22a, 22b.On the other hand, Figure 28 shows not have mounting disc 100 on it and to have shown that valve 21,22 exposes the skeleton view of the tray salver 308 of chuck and magnetic head opening 11c, 11h state.As shown in figure 28, when valve 21,22 was opened, dish folder 21a, 21b, 22a, 22b were stored in the outside of the dish storage compartment 10d of box body 10.
Secondly, also specify the structure and the operation of valve 21,22 with reference to Figure 29,30 and 31.Figure 29 is the partial section along the tray salver 308 that passes dish 100 central planes.As shown in figure 29, the inner surface 12i of box body 10 is provided with notch part 10w so that can not interfere the unlatching and the closed procedure of valve 21,22.In addition, box body 10 also comprises the valve storage compartment 10s that is used to store a part of valve of having opened 21,22.In addition, as shown in figure 29, when valve 21,22 is closed, at least each other at chuck and magnetic head opening 11c and the edge 21f of the valve 21,22 of adjacency and the 22f overlap joint (that is, along the thickness direction that coils 100) that is perpendicular to one another above the 11h.
On the other hand, as shown in figure 30, each of dish folder 21a, 21b, 22a, 22b all comprise and being suspended on above dish 100 raised zones, and with inclined-plane 21a ', 21b ', 22a or the 22b ' of the outward flange overlap joint of dish 100.That is to say that as shown in figure 30, inclined-plane 21a ', 21b ', 22a ' or 22b ' have to the sectional area of inferior pyramidal and to dish 100.When chuck and magnetic head opening 11c and 11h were coated with valve 21,22, inclined-plane 21a ', 21b ', 22a ' or 22b ' can contacts with the outward flange 100c of dish 100, coiled 100 and along thickness direction 100t compression plate 100 thereby clamp thereon.As a result, thin plate 21p, the 22p of valve 21,22 contacts with the signal record side 100A of dish 100, is fixed in the box body 10 and coil 100.In this state, the signal record side 100A of dish 100 closely contacts with thin plate 21p, 22p when closure.Therefore, do not have dust deposit on the 100A of signal record side.
In addition, if if manually rotating disc 100 expose side or closure or openness valve 21,22 consciously, then can dust out, finger mark or any other bonded to foul on the signal record side 100A of dish 100.
In addition, as shown in figure 31, valve 21 comprises valve opener/closer 21t, elastic part 21v and locking projection 21k.These parts 21t, 21v and 21k form the global facility of valve 21.Specifically, valve opener/closer 21t is used for opening outside and closure flap 21.Locking projection 21k is connected to valve 21 by elastic part 21v.As shown in figure 31, when valve 21 covered chuck and magnetic head opening 11c and 11h, the locking projection 21k that applies elastic force from elastic part 21v cooperated with the locking hole 10k of box body 10, thereby prevented valve 21 rotations and valve 21 is fixed to box body 10.When valve 21 fixedly the time, also fixed another valve 22 with last valve 21 interlockings by the 20c of interlock mechanism.
Therefore, locking projection 21k is compressed by arrow 20A indicated direction outside by for example projection, and when compressing opener/closer 21t by arrow 20B indicated direction release lock tieholen 10k, chuck and magnetic head opening 11c and 11h are exposed in valve 21,22 rotations, can unclamp from dish folder 21a, 21b, 22a, 22b and coil 100.Therefore, can prevent that the user is not intended to shift out dish 100.
Below, also with reference to Figure 24 and 32 structure and operation of listed price block 23 specifically.Figure 32 shows to be inverted extensible dish block 23.As shown in figure 24, projection 23a, the 23b of dish block 23 and 23c match with recess 12a, 12b and the 12c of the upper shell 12 that is provided for close its dish window 12w respectively.Therefore, if these projections 23a, 23b separate with 12c with recess 12a, 12b with 23c, then can shift out dish block 23 from upper shell 12.
Then, specify with reference to Figure 33 and be used to prevent that the user from injecting this tray salver 308 mechanism of disk drive along the opposite way round.Figure 33 shows along the tray salver 308 of the 1B of direction shown in Figure 23 (referring to Figure 23) to insert the front view of side.As shown in figure 33, box body 10 is included in the recess 10g on the one side surface and injects the direction 1A of disk drives (referring to Figure 23) at tray salver 308 asymmetric.Recess 10g is not positioned at the center of box body 10 thickness.
By the recess that is used for tray salver 308 like this 10g is provided, have only when its corresponding projection that is provided for disk drive when recess 10g cooperates therewith, tray salver 308 can correctly inject disk drive and disk drive can normally be operated.
In other words, even if the user attempts tray salver 308 is inverted the reeve disk drive mistakenly, he or she can not inject disk drives with tray salver 308.This is because the projection of respective disc driver is interfered with the opposite side surface of the tray salver 308 that does not have recess 10g.In addition, even if the user attempts tray salver 308 to be inverted and to be injected disk drive along wrong mode mistakenly, he or she can not inject disk drive with tray salver 308.This is to interfere because the projection of disk drive also will produce with the part that has recess 10g side surface and do not have groove.Therefore, can prevent that the user from injecting tray salver 308 mistakenly.
The tray salver 308 of above-mentioned the 8th preferred implementation has many improved procedures.
For example, the thickness of box body 10 can also further be reduced to following degree, so that when valve 21,22 closures, dish block 23 can not protrude from the upper surface 12f of upper shell 12 (referring to Figure 24).In the case, when valve 21,22 will be closed, dish folder 21a and 22a can be below dish block 23 the projection 23a of promotion dish block 23 upwards respectively, thereby dish block 23 is protruded from the upper surface 12f of upper shell 12.According to this structure, dish 100 is rotated in dish storage compartment 10d in abundant wide space and the thickness of tray salver 308 can further reduce.
In addition, dish block 23 can form the global facility of box body 10.In the case, dish block 23 should be able to be almost vertically crooked so that fixing dish 100 can shift out.
In addition, shutter spring 31 and 32 can apply elastic force so that open valve 21,22 along this direction.If valve 21,22 can almost completely synchronously be operated by interlock mechanism, then can omit one of shutter spring 31 and 32.
In above-mentioned preferred implementation, locking projection 21k forms the global facility of valve 21.On the other hand, its end comprises that the check lock lever of locking projection and projection can be connected to box body 10 by elastic part, and the corresponding recess that also can be provided for valve is so that protrusion and recess are fitted to each other.In the case, the locking hole by box body compresses the locking projection, and these protrude and recess can be separated from one another, so that valve is rotated freely.Selectively, the same as shutter spring (that is, elastic component) in other preferred implementation, check lock lever can be the resin spring that forms box body 10 global facilities.

As shown in figure 35, lower house 41 comprises chuck opening 41c and magnetic head opening 41h.Chuck opening 41c makes chuck spare (spindle motor that for example, is used for rotating disc 100) enter tray salver 309 from the outside.Magnetic head opening 41h make from/read and/or the magnetic head of write signal enters tray salver 309 and reaches the target location at dish 100 at dish 100 signal record side 100A.Lower house 41 is in the face of the signal record side 100A of dish 100.In addition, magnetic head opening 41h arrives the side of lower house 41.
Upper shell 42 comprises to be made dish 100 can enter and shift out tray salver 309 and extends to expose the circular discs window 42w of dish 100 at the whole raised zones of dish 100.Upper and lower casing 42,41 is bonding or weld together on its excircle, thereby forms box body 40.
The dish storage compartment 40d that is used for storage disks 100 therein limits by the first inside surface 41u and the second inside surface 42i of box body 40.The first inside surface 41u is relative with dish 100 signal record side 100A, and the second inside surface 42i has and is approximately circular shape and is limited in the dish window 42w.That is to say that the first inside surface 41u is the bottom of dish storage compartment 40d.
In dish storage compartment 40d, width enough can make dish 100 gaps that rotate freely be arranged on the second inside surface 42i and coil between 100 the excircle.In addition, the top of dish storage compartment 40d is circular discs window 42w, so that expose in dish window 42w one of side that is stored in the dish 100 that coils storage compartment 40d.
Dish block 42a, 42b, 42c and 42d form the global facility of upper shell 42, so that local the protrusion advances to coil window 42w.Each of these dish blocks 42a, 42b, 42c and 42d all separated with upper shell 42 by the slit.These dishes block 42a, 42b, 42c and 42d are used to prevent to coil 100 and fall from dish window 42w.When this tray salver 309 was put in the disk drive of vertical fixing, dish block 42a, 42b, 42c and 42d were effective especially.These dish blocks 42a, 42b, 42c and 42d can select to make an integral body by elastic component and upper shell 42.
Valve 51 and 52 is arranged between the first inside surface 41u of dish 100 signal record side 100A and box body 40.Valve 51 and 52 comprises axis hole 51u and 52u respectively.These axis holes 51u and 52u are with the state that rotates freely and the dish storage compartment 40d outside that is positioned at box body 40 and the axle 41s cooperation on the dark side of the box body 40 of relative its magnetic head opening 41h.Like this, valve 51 and 52 rotates on axle 41s, so that cover or expose chuck and magnetic head opening 41c and 41h.
Cam 51c and engaged wheel 52c are separately positioned on axis hole 51u and the 52u near valve 51 and 52.Cam 51c and engaged wheel 52c have the shape that is engaged with each other and constitute the 50c of interlock mechanism that is used to open with closure flap 51 and 52 together when it are interlocked each other.
Valve 51 relative with dish 100 signal record side 100A and 52 upper surface separately are coated with and are used to prevent to coil protective layer 51p and the 52p that 100 signal record side 100A is swiped or attracts dust.
Protective layer 51p and 52p can choose suitable material from the group that anti-scratch non-woven fibre, dustproof non-woven fibre, anti-scratch coating and dustproof coating are formed.In this preferred implementation, can the thin plate of the non-woven fibre that prevents dust is bonding respectively or be ultrasonically bonded on valve 51 and 52 as protective layer 51p and 52p.
Shutter spring 61 and 62 is separately positioned on the outside of the dish storage compartment 40d that is used for valve 51 and 52.These springs 61 and 62 are applied to valve 51 and 52 and along this direction closure flap 51 and 52 with elastic force.On the other hand, shutter spring 61,62 also can be applied to valve 51 and 52 and open valve 51 and 52 along this direction along this direction with elastic force.In addition, if valve 51 and 52 can omit one of shutter spring 61 and 62 by almost completely synchronous operation of interlock mechanism.
As above-mentioned the 8th preferred implementation, as shown in figure 35, valve 51 and 52 each all comprise two dish folders 51a, 51b and 52a, 52b at its two ends.In addition, as what will specify in the back, projection 51e and 52e are formed at respectively on valve 51 and 52, are positioned at when closed with convenient valve 51 and 52 below the center pit of dish 100.
As shown in figure 34, the upper surface of box body 40 (or upper shell 42) has embossing arrow mark (or recess) the 40a indicated direction (arrow 1A) that this tray salver 309 should inject the disk drive direction.Box body 40 also is included in two recess 40c that are parallel on two side surfaces of direction 1A that tray salver 309 injects disk drives.When tray salver 309 embeds or puts into disk drive or when tray salver 309 was stored in the disc changer, these recesses 40c both can be used to advance groove, also can be used as detent.As selection mode, tray salver 309 has only a side surface can comprise recess 40c.In the case, recess 40c can be used to prevent that the user is inverted reeve mistakenly or puts into tray salver 309.The upper surface of box body 40 also comprises the clamper 40e that allows the user clamp tray salver 309.This clamper 40e has anti-skidding embossing shape.
Figure 36 shows that not coiling 100 is stored in wherein and valve 51 and 52 covers the skeleton view of tray salver 309 of the state of chucks and magnetic head opening 41c and 41h.Figure 37 shows that not coiling 100 is stored in wherein and valve 51 and 52 exposes the skeleton view of tray salver 309 of the state of chuck and magnetic head opening 41c and 41h.
Hereinafter, also will the structure and the operation of valve 51 and 52 further be specified.Shown in Figure 34 and 35, valve 51 and 52 dish folder 51a, 51b and 52a, 52b also have be suspended on equally above dish 100 raised zones with the 8th preferred implementation and with the cross sectional shape of the outward flange overlap joint of dish 100.That is to say that the inclined-plane is to tilt to inferior pyramidal and to dish 100.Therefore, the effect of above-mentioned the 8th preferred implementation also can reach by the 9th preferred implementation.
In addition, valve 52 comprises the valve opener/closer 52t that is used for opening outside with closure flap 52, and valve 51 comprises the elastic part 51v and the locking projection 51k of parts as a whole.As shown in figure 35, tightly lock projection 51k and be connected to valve 51 by elastic part 51v.Therefore, when chuck and magnetic head opening 41c and 41h are coated with valve 51 and 52, the locking projection 51k that applies elastic force from elastic part 51v cooperates with the locking hole 40k of box body 40 (or lower house 41), thereby at non-rotating state valve 51 is fixed to box body 40.When valve 51 in this way fixedly the time, also will be fixed with another valve 52 of valve 51 interlockings by the 50c of interlock mechanism.
Therefore, only make locking projection 51k outside by projection, for example, compressing by arrow 50A indicated direction, simultaneously, unclamping locking hole 40k when compressing opener/closer 52t by arrow 50B indicated direction, valve 51 and 52 could rotate to expose chuck and magnetic head opening 41c and 41h, just can unclamp dish folder 51a, 51b, 52a, 52b and coil 100.Therefore, can prevent that the user from shifting out dish 100 unintentionally.
Unlike the 8th above-mentioned preferred implementation, locking projection 51k is arranged on opener/closer 52t and is used for two different valve 51 and 52 in this preferred implementation.This structure has special effect for the tray salver of small-sized disc.This is should have relatively little size because be used for the tray salver and the valve thereof of small-sized disc, and it normally is difficult to be provided for designing the locking projection and the opener/closer of the single valve outside the consideration.In addition, even when single valve can comprise locking projection and opener/closer, very narrow gap will make between the tripping-gear on valve opened/closed mechanism and the disk drive side or these two mechanisms all need form in very limited space, thereby be difficult to the disk drive that design consideration needs.
In above-mentioned preferred implementation, locking projection 51k forms the global facility of valve 51.Mode as an alternative, its end comprise that the check lock lever of locking projection and projection can be connected to box body 40 by elastic part, also can be provided for the corresponding recess of valve, so that protrude and recess is fitted to each other.In this case, the locking hole by box body compresses the locking projection, and these protrude and recess can be separated from one another, so that valve is rotated freely.Selectively, in other preferred implementation, can be the resin spring of the global facility that forms box body 40 together with the check lock lever of shutter spring (that is elastic component).
Below, will illustrate also how projection 51e and the 52e on valve 51 and 52 works.Figure 38 is the partial section that shows along the tray salver 309 of the planar interception that passes dish 100 centers.As shown in figure 38, when valve 51 and 52 when closed, projection 51e and 52e protrude the into center pit 100h of dish 100, contact with 52 with valve 51 thereby coil 100.
As shown in figure 39, when valve 51 and 52 will be opened, projection 51e and 52e slided in center pit 100h below dish 100 the downside, thereby dish 100 is risen from valve 51 and 52.In this mode, when valve 51 and 52 will closure or openness, the signal record side 100A of dish 100 will can be by valve 51 and 52 scrapings.In addition, projection 51e that moves along with the closure or openness of valve 51 and 52 and 52e are in the signal recording area of signal record side 100A.Therefore, projection 51e and the 52e signal recording area that will can not contact or swipe.
Then, with reference to the structure and the operation of Figure 40 and 41 explanation dish blocks.Figure 40 is the partial section that shows along tray salver 309 parts around the dish excircle of the planar interception that passes dish 100 centers.As shown in figure 40, projection 42a ', 42b ', 42c ' or 42d ' are formed on the bottom surface of dish folder 42a, 42b, 42c, 42d.When valve 51 and 52 closures, dish folder 42a, 42b, 42c, 42d are basically parallel to the surface of dish 100 and fall within the thickness of tray salver shown in Figure 40 309.The profile of the tray salver 309 in this state as shown in figure 36.
On the other hand, as shown in figure 41, when valve 51 and 52 was opened, valve 51 contact with projection 42a ', 42b ', 42c ' or 42d ' respectively with 52 inclined-plane 52f, 51f, 51d and 52d, thereby lifting dish folder 42a, 42b, 42c, 42d are to coiling above 100.The profile of the tray salver 309 in this state as shown in figure 37.By using this structure, particularly after tray salver 309 is vertically put into disk drive and at dish 100 by the gap before clamping, can prevent to coil 100 and fall from tray salver 309.In addition, when coiling 100 when clamping, dish 100 can be in openr spatial movement.In addition, this structure also can be used for further reducing the thickness of tray salver.
Should be noted that inclined-plane 52f, 51f, 51d and 52d can have protrusion or the recess that cooperates with projection 42a ', 42b ', 42c ' or 42d ' in order to make valve 51 and 52 keep temporary transient opening.

The dish storage compartment 70d that is used for storage disks 100 therein limits by the first inside surface 71u and the second inside surface 72i of box body 70.The first inside surface 71u is relative with dish 100 signal record side 100A, and the rounded substantially shape of the second inside surface 72i and being limited in the dish window 72w.That is to say that the first inside surface 71u is the bottom of dish storage compartment 70d.
In dish storage compartment 70d, width enough can make dish 100 gaps that rotate freely be arranged on the second inside surface 72i and coil between 100 the excircle.In addition, the top of dish storage compartment 70d is circular discs window 72w, and expose in dish window 72w one of side that is stored in the dish 100 that coils storage compartment 70d like this.
Valve 81 and 82 is arranged between the first inside surface 71u of dish 100 signal record side 100A and box body 70. Valve 81 and 82 comprises axis hole 81u and 82u respectively.These axis holes 81u and 82u are with the state that rotates freely and the dish storage compartment 70d outside that is positioned at box body 70 and the axle 71s cooperation on the dark side of the box body 70 of relative its magnetic head opening 71h.Therefore, valve 81 and 82 rotates on axle 71s, so that cover or expose chuck and magnetic head opening 71c and 71h.
Cam 81c and engaged wheel 82c are set to axis hole 71u and the 72u near valve 81 and 82 respectively.Cam 81c and engaged wheel 82c have the shape that is engaged with each other and constitute the 80c of interlock mechanism that is used to open with closure flap 81 and 82 together when it are interlocked each other.
Valve 81 relative with dish 100 signal record side 100A and 82 upper surface separately are coated with and are used to prevent to coil protective layer 81p and the 82p that 100 signal record side 100A is swiped or attracts dust.
Protective layer 81p and 82p can choose suitable material from the group that anti-scratch non-woven fibre, dustproof non-woven fibre, anti-scratch coating and dustproof coating are formed.In this preferred implementation, can the thin plate of the non-woven fibre that prevents dust is bonding respectively or be ultrasonically bonded to valve 81 and 82 as protective layer 81p and 82p.
Shutter spring 91 and 92 is separately positioned on the outside of the dish storage compartment 70d that is used for valve 81 and 82.These springs 91 and 92 are applied to valve 81 and 82 and along this direction closure flap 81 and 82 with elastic force.On the other hand, shutter spring 91 and 92 also can be applied to valve 81 and 82 and open valve 81 and 82 along this direction along this direction with elastic force.In addition, if valve 81 and 82 is almost completely synchronously operated by the 80c of interlock mechanism, can omit one of shutter spring 91 and 92.
As above-mentioned the 8th preferred implementation, as shown in figure 43, valve 81 and 82 each all comprise two dish folders 81a, 81b and 82a, 82b at its two ends.In addition, as the 9th preferred implementation, projection 81e and 82e also are formed at respectively on valve 81 and 82.
In addition, as what will specify in the back, dish block 81f, 81d and 82d are separately positioned on the position that presss from both sides 81a, 81b and 82a near dish as the global facility of valve 81 and 82.On the other hand, these dish blocks 81f, 81d and 82d can make an integral body by elastic component and valve 81 and 82.
As shown in figure 42, the upper surface of box body 70 (or upper shell 72) has embossing arrow mark (or projection) 70a of the direction (arrow 1A) that is used to indicate tray salver 310 should inject disk drive.Box body 70 also is included in two recess 70c that are parallel on two side surfaces that inject tray salver 310 direction 1A.When tray salver 310 pushes or puts into disk drive or when tray salver 310 is stored in the disc changer, these recesses 70c both can also can be used as detent as advancing groove.Selectively, tray salver 310 has only a side surface can comprise recess 70c.In the case, recess 70c can be used to prevent that the user is inverted reeve mistakenly or puts into tray salver 310.The upper surface of box body 70 also comprises the controller 70e that allows the user control tray salver 310.This controller 70e has anti-skidding embossing shape.

Hereinafter, also will further specify the structure and the operation of valve 81 and 82.Shown in Figure 42 and 43, valve 81 and 82 dish folder 81a, 81b and 82a, 82b also have be suspended on equally above dish 100 raised zones with the 8th preferred implementation and with the cross sectional shape of the outward flange overlap joint of dish 100.That is to say that the taper that the inclined-plane is downward is also tilted to dish 100.Therefore, the effect of above-mentioned the 8th preferred implementation also can reach by this tenth preferred implementation.
In addition, valve 82 comprises the valve opener/closer 82t that is used for opening outside with closure flap 82, and the elastic part 82v and the locking projection 82k of parts as a whole.As shown in figure 43, locking projection 82k is connected to valve 82 by elastic part 82v.Therefore, when chuck and magnetic head opening 71c and 71h are coated with valve 81 and 82, the locking projection 82k that applies elastic force from elastic part 82v cooperates with the locking hole 70k of box body 70 (or lower house 71), thereby at non-rotating state valve 82 is fixed to box body 70.When valve 82 in this way fixedly the time, will be fixed with another valve 81 of valve 82 interlockings by the 80c of interlock mechanism.
Therefore, only make locking projection 82k from the outside by projection, for example, along compressing by arrow 70A indicated direction, simultaneously, when unclamp locking hole 70k being compressed opener/closer 82t by arrow 70B indicated direction when, valve 81 and 82 could rotate to expose chuck and magnetic head opening 71c and 71h, and dish 100 just can unclamp dish folder 81a, 81b, 82a, 82b.Like this, can prevent that the user from shifting out dish 100 unintentionally.
In above-mentioned preferred implementation, locking projection 82k forms the global facility of valve 82.On the other hand, comprise that in its end the check lock lever of locking projection and projection can be connected to box body 70 by elastic part, also can be provided for the recess of valve, so that protrusion and recess are fitted to each other.In the case, the locking hole by box body compresses the locking projection, and these protrude and recess can be separated from one another, so that valve is rotated freely.Selectively, in other preferred implementation, can be the resin spring of the global facility that forms box body 70 together with the check lock lever of shutter spring (that is elastic component).
Then, also structure and the operation of listed price folder 81f, 81d and 82d specifically.Shown in Figure 46 and 48, when valve 81 and 82 closures, dish folder 81f, 81d and 82d are basically parallel to the surface of dish 100, and can not protrude from the upper surface of tray salver 310.Profile at the tray salver 310 of this state shows in Figure 44.
On the other hand, shown in Figure 47 and 49, when valve 81 and 82 will be opened, dish block 81f, 81d and 82d be by the otch 70s and the inclined-plane 72s guiding of box body 70, so as to rise to dish 100 above.As shown in figure 49, when inclined-plane 72s was formed at the interior upper surface of box body 70, as shown in figure 47, otch 70s was formed on the madial wall of box body 70.In addition, upper shell 72 is provided with notch part 72a, 72b and 72c, does not interfere so that can not produce with dish folder 81f, 81d that has promoted and 82d.Profile at the tray salver 310 of this state shows in Figure 45.
When valve 81 and 82 when closed, dish block 81f, 81d and 82d be suspended on the raised zones of dish 100 and with the excircle overlap joint of dish 100.Therefore, dish folder 81f, 81d and 82d be along compressing valve 81 and 82 on the thickness direction, thereby clamp thereon.Therefore, also can from valve 81 and 82, press from both sides 81a, 81b, 82a and 82b by the omission dish.
By using this structure, particularly after tray salver 310 is vertically put into disk drive and coiling 100, can prevent to coil 100 and from tray salver 310, fall by the gap before clamping.In addition, when coiling 100 when clamping, dish 100 can be in openr spatial movement.In addition, this structure also can be used for further reducing the thickness of tray salver.

Hereinafter, specify tray salver 312 with reference to corresponding accompanying drawing according to this aspect the 12 concrete preferred implementation.
Different with the tray salver 311 of above-mentioned the 11 preferred implementation, the tray salver 312 of the 12 preferred implementation comprises around the flange 12t of box body 10 inner surface 12i and around the ring 20w of the hole 20h that limits by valve 21,22.These features will illustrate below.
Shown in Figure 58, flange 12t protrudes to the inner periphery of dish 100 from the inner surface 12i of upper shell 12, and substantially around the excircle that coils storage compartment 10d.Figure 59 is the cut-open view that display panel 100 is stored in the tray salver 312 when coiling storage compartment 10d state.Shown in Figure 59, when valve 21,22 closures, the outward flange of the signal record side 100A of dish 100 contacts with flange 12t.As a result, dish 100 excircle and the gap-closing between the box body 10, thus prevent the signal record side 100A of dust arrival dish 100.
In addition, gap 10w is arranged between the flange 12t and lower house 11 of box body 10.Therefore, shown in Figure 60 and 61, when valve 21,22 was opened, the various piece of valve 21,22 entered gap 10w, thereby prevented that valve 21,22 and box body 10 from producing interference.
Yet shown in Figure 59, in this structure, when valve 21,22 closures, another gap 10z that is directed to air also will produce between dish 100 and valve 21,22.For closed this gap 10z, valve 21,22 comprises projection 21w and the 22w around the center pit 100h of dish 100 respectively.Shown in Figure 58, when valve 21,22 closures, these two projection 21w and 22w are close together each other, thereby form the ring 20w of the gap 10z of closed hoop drum center pit 100h.As a result, do not have the signal record side 100A of dust by center hole 100h arrival dish 100.
Yet the top of these projections 21w and 22w also may contact with the signal record side 100A of dish 100.Therefore, in optimal way, the edge of projection 21w and 22w should be circle, so that signal record side 100A that can scraping dish 100.Selectively, projection 21w and 22w also can form the global facility of valve 21,22 respectively.In the case, preferably that anti-scratch non-woven fibre is bonding or be ultrasonically bonded to this part of the ring 20w that contacts with the signal record side 100A that coils 100 or preferably form anti-scratch coating in this part.Mode as an alternative, projection 21w and 22w itself also can be made by anti-scratch non-woven fibre or anti-scratch coating respectively and be directly bonding or be ultrasonically bonded to valve 21,22.
In addition, shown in Figure 59, when valve 21,22 closures, dish 100 rises to above the valve 21,22 by ring 20w and flange 12t, and leaves gap 10z therebetween.That is to say that the signal record side 100A of most of dish 100 does not contact with valve 21,22.Therefore, for example, even the non-woven fibre that the surface of valve 21,22 need not be anti-scratch covers, signal record side 100A still can not swiped.
Figure 62 and 63 shows alternative projection 21w ' and the 22w ' that has extended to the excircle that coils 100.Specifically, Figure 62 is the state that shows valve 21,22 closures, and Figure 63 is the state that shows that valve 21,22 is opened.
Shown in Figure 62 and 63, when valve 21,22 was opened, projection 21w ' and 22w ' were preferably placed at the flange 12t interior (that is the position at the center of more close dish storage compartment 10d) of dish storage compartment 10d.Therefore, projection 21w ' can not contact with flange 12t or interfere with 22w '.
Selectively, projection 21w ' and 22w ' also can form global facility with valve 21,22 respectively.In the case, preferably that anti-scratch non-woven fibre is bonding or be ultrasonically bonded to these parts of coiling 100 projection 21w ' that contact and 22w ' or preferably form anti-scratch coating thereon.Mode as an alternative, projection 21w ' and 22w ' itself also can be made by anti-scratch non-woven fibre or anti-scratch coating respectively and be directly bonding or be ultrasonically bonded on the valve 21,22.

Hereinafter, specify tray salver 313 with reference to corresponding accompanying drawing according to this aspect the 13 concrete preferred implementation.
At first, the construction profile of drawing tray salver 313 with reference to Figure 64 and 65.As the 8th preferred implementation, shown in Figure 64 and 65, dish 100 also comprises first and second sides.Usually first side of the dish 100 of printed label shows in Figure 64, and second side, that is, and the back of signal record side 100A for showing among Figure 65.
Shown in Figure 64 and 65, tray salver 313 comprises lower house 11, upper shell 12, a pair of valve 21,22 and dish block 23.
Shown in Figure 65, lower house 11 comprises chuck opening 11c and magnetic head opening 11h.Chuck opening 11c makes chuck spare (spindle motor that for example, is used for rotating disc 100) enter tray salver 313 from the outside.Magnetic head opening 11h make from/read and/or the magnetic head of write signal enters tray salver 313 and reaches the target location at dish 100 at dish 100 signal record side 100A.Lower house 11 is in the face of the signal record side 100A of dish 100.Lower house 11 is by becoming predetermined shape to form molding synthetic resin.
Magnetic head opening 11h arrives a side surface of lower house 11.For the rigidity that reduces to cause because there being magnetic head opening 11h lower house 11 reduces, lower house 11 comprises the bridge 11b that links together of two ends with magnetic head opening 11h.Lower house 11 also comprises two pilot hole 11w that combine with the register pin (not shown) of disk drive.
Upper shell 12 comprise can make dish 100 enter and shift-in/go out tray salver 313 and be extended to whole raised zones top of dish 100 to expose the circular discs window 12w that coils 100 upper sides.Upper and lower casing 12,11 is bonding or weld together at its excircle, thereby forms box body 10.Upper shell 12 is made by synthetic resin.
Be used for the dish storage compartment 10d that dish 100 is stored in is wherein limited by lower surface 11u and inner surface 12I in the box body 10.Interior lower surface 11u is relative with dish 100 signal record side 100A, and inner surface 12i is rounded substantially and be limited in the dish window 12w.That is to say that interior lower surface 11u is the bottom of dish storage compartment 10d.
In dish storage compartment 10d, width enough can make dish 100 gaps that rotate freely be arranged on inner surface 12i and coil between 100 the excircle.In addition, the top of dish storage compartment 10d is dish window 12w, so that expose in dish window 12w one of side that is stored in the dish 100 that coils storage compartment 10d.
Shown in Figure 64 and 65, two movably dish folder be provided for upper shell 12 so that protrude to advance to coil in the window 12w partly.Upper shell 12 also is provided with the 3rd dish block 12s, advances to coil window 12w so that protrude.The 3rd dish block 12s forms the global facility of a upper shell 12.These three dishes block 23 and 12s substantially around the circumference of dish window 12w by evenly being provided with at interval, to prevent that coiling 100 falls from dish window 12w.In addition, two protrusion dish contact portion 12s ' are formed on the dish block 12s.For dish 100, almost the dish contact portion 23a with dish block 23 is high equally for these dish contact portions 12s '.
According to this structure, even tray salver 313 vertical or inversion installations, tray salver 313 also can be clamped dish 100 and can not fall.That is to say that when tray salver 313 vertical reeves or inversion reeve disk drive, this tray salver 313 also can prevent to coil 100 especially effectively and fall.Should be noted that and from tray salver 313, to shift out dish block 23.Mode as long as dish block 23 can rotate or crooked quoad hoc, so that allow the user shift out dish 100 from tray salver 313, also can be fixed to upper shell 12 with dish block 23 in dish storage compartment 10d as an alternative.
Valve 21,22 is on the single plane between the interior lower surface 11u of dish 100 signal record side 100A and box body 10. Valve 21,22 comprises axis hole 21u and 22u respectively.These axis holes 21u and 22u cooperate with axle 11s at the state that rotates freely, and described axle 11s is positioned at the disk storage part 10d outside of box body 10 and is positioned on the dark side of the box body 10 relative with magnetic head opening 11h.Like this, valve 21,22 rotates on axle 11s in the following manner, covers or exposes chuck and magnetic head opening 11c and 11h.Valve 21,22 is also made by synthetic resin.
Loop section 21c and pin part 22c are separately positioned near the axis hole 21u of valve 21,22 and the position of 22u.Loop section 21c and pin part 22c have the shape that is fitted to each other and are configured for the 20c of interlock mechanism of unlatching and closure flap 21,22 when it is interlocked each other together.The 20c of interlock mechanism also can adopt cam structure or gear mechanism to realize.
The upper surface separately of the valve 21,22 relative with dish 100 signal record side 100A is coated with and is used to the protective layer 21p and the 22p that prevent to coil 100 signal record side 100A scraping or inhale dust.
Protective layer 21p and 22p can choose suitable material from the group that anti-scratch non-woven fibre, dustproof non-woven fibre, anti-scratch coating and dustproof coating are formed.In this preferred implementation, can the thin plate of the non-woven fibre that prevents dust is bonding respectively or be ultrasonically bonded on valve 81 and 82 as protective layer 81p and 82p.
The locking mating part 22k that cooperates with locking projection 21k is provided for valve 22, and locking projection 21k is provided for valve 21.Locking projection 21k and locking mating part 22k are configured for locking each other and opening the latch mechanism 20k of valve 21,22 together.By utilizing the 20k of this mechanism, can automatically lock and open valve 21,22, thereby prevent that the user from opening valve 21,22 unintentionally.In addition, also can prevent to coil 100 signal record side 100A is stained with dust, finger mark or scraping occur.Locking projection 21k and locking mating part 22k form the global facility of valve 21,22 respectively.
In addition, valve 21,22 is respectively arranged with recess 21h and 22h.When valve 21,22 was closed, these recesses 21h and 22h contacted with each other with formation hole 20h below dish 100 center pit 100h just.In the case, the diameter of hole 20h coils the diameter of 100 center pit 100h no better than.In this structure, even being placed to the upper side of dish 100, exposes up this tray salver 313, do not have dust deposit on valve 21,22 yet.In addition, even tray salver 313 upside down do not have dust yet and directly are deposited on dish 100 the signal record side 100A.
As the 8th preferred implementation that has illustrated, each of valve 21,22 all comprises two dish folders 21a, 21b, 22a and 22b at its two ends.These dish folders 21a, 21b, 22a and 22b are arranged to basic circumference with even spaced ring drum 100. Dish folder 21a, 21b, 22a and 22b form the global facility of valve 21,22.When valve 21,22 was closed, each of these dishes folder 21a, 21b and 22a, 22b all had the outward flange that cross sectional shape (or inclination) to inferior pyramidal is clamped dish 100.By these inclined-planes are set, when valve 21,22 closures, valve 21,22 can be clamped and compress to dish 100 securely.
In this preferred implementation, only there is the folder of coiling 21b not to be fixed to valve 21, still connect on it and and freely rotate at radially (that is the center position of dish 100) that coil 100 by elastic part 21d.Therefore, dish folder 21a, 21b and 22a, 22b can clamp the dish 100 with any different-diameter or thickness securely, and dish 100 is arbitrarily moved.
Be used to open with the valve opener/closer 22t of closure flap 22 and make the as a whole leading flank that is formed at the tray salver 313 relative with axis hole 22u with valve 22, that is, and near the position of dish folder 22a.When valve 21,22 was connected to box body 10, valve opener/closer 22t was positioned at below the bridge 11b and at magnetic head opening 11h.At closure or openness valve 21,22 o'clock, opener/closer 22t moved along the bridge 11b in the magnetic head opening 11h.In this preferred implementation, do not need to be respectively box body 10 any gap that the valve opener/closer 22t moves that is used to make is set.In other words, owing to do not need additionally to be provided for the gap of box body 10, therefore, dust can undesirably not enter box body 10.In addition, valve opener/closer 22t can be arranged in the magnetic head opening 11h of box body 10, thereby a kind of tray salver of better structure of simplification is provided.
Shown in Figure 66, when closure, valve 21,22 does not contact with each other fully along the line, but has many contact portions of not aliging with line.More particularly, valve 21,22 has the first couple of contact portion 21f on chuck opening 11c and 22f and second couple of contact portion 21g on magnetic head opening 11h and 22g respectively.In this preferred implementation, contact portion 21f and 22f contact with each other along the center line of tray salver 313.On the other hand, contact portion 21g and 22g contact with each other along the line of the predetermined angular that limits with the center line of tray salver 313 (for example, near 15 ° near 16 °).When valve 21,22 had this shape, valve 22 had at the global shape of valve opener/closer 22t close region and can show sufficiently high rigidity.
Shutter spring 31 and 32 is separately positioned on the outside of the dish storage compartment 10d that is used for valve 21,22.These springs 31 and 32 are applied to valve 21,22 with elastic force and along this direction closure flap 21,22.On two fulcrum bar of the spring 11t on the interior lower surface 11u of shutter spring 31 and 32 reeve box bodys 10.In this preferred implementation, with torsion-coil spring as shutter spring 31 and 32.In optimal way, torsion- coil spring 31 and 32 has same shape to reduce cost.The embodiment that can be used as shutter spring 31 and 32 other resilient materials that use comprises compression spring, sheet spring and elastic resin spring.
Shown in Figure 65, tray salver 313 comprises among the groove 11v that injects lower house 11 so that the write protector 40 that slides along groove 11v.By slip write protector 40, can mobile projection 40t, thus closure or openness are provided for the sensing switch of disk drive.In this mode, writing and can forbid on dish 100 also can allow.
That is to say that this tray salver 313 is made up of lower and upper housing 11 and 12 box bodys of forming 10, dish block 23, valve 21,22, shutter spring 31,32 and write protector 40.
Instantly, when upper shell 11,12 links together, two axle 11s of lower house 11 cooperate with two projection 12h of upper shell 12.In this mode, can increase the rigidity of a 11s.Therefore, even when valve 21,22 is opened,, can produce the moment of torsion that reduces at the place of rotation center separately of valve 21,22 by the elastic force that applies from shutter spring 31 and 32.As a result, valve 21,22 can be opened to the angle that needs.
Shown in Figure 64, the upper surface of box body 10 (or upper shell 12) has the user can write down the label plane 10f that is stored in the content in the dish 100, and represents that this dish 313 should inject embossing arrow mark (or recess) 10a of disk drive direction (arrow 1A).
Box body 10 also comprises the two couples of recess 10c and the 10e that is parallel on two side surface that dish 313 injects direction 1A.When tray salver 313 advances and puts into disk drive or when tray salver 313 stores disc changer, these recesses 10c and 10e both can be used as and had embedded the recess use, also can be used as positioning recess and used.Box body 10 also is included in the slit 10b on the one side surface.Slit 10b can be used as recess and uses, and judges the upper and lower of tray salver 313 when tray salver 313 injects disk drive.
Hereinafter, how specify this tray salver 313 with reference to Figure 66,67,68 and 69 operates.Figure 66 and 67 shows the cut-open view of tray salver 313 in valve 21,22 closure states and valve 21,22 openings respectively.Figure 68 is the cut-open view that shows valve latch mechanism 20k.And Figure 69 is the concrete sectional view that shows the dish hole 22a of valve 22.
At first, with the storing state of explanation tray salver 313, that is, do not put into the state of the tray salver 313 of disk drive.In this state, shown in Figure 66, valve 21,22 closures.In addition, shown in Figure 69, the inclined-plane 22a ' of the dish of valve 22 folder 22a contacts with the outward flange of dish 100, coils and along thickness direction 100t compression plate 100 thereby clamp thereon.As a result, the signal record side 100A of dish 100 is contacted with the thin plate 22p of valve 22, be fixed in the box body 10 and coil 100.Three other dish folder 21a, 21b and 22b also have its inclined-plane 21a ', 21b ' and 22b ' separately respectively.Therefore, as dish folder 22a, these dishes folder 21a, 21b and 22b also clamp and will coil 100 and be fixed in the box body 10.
In this state, the signal record side 100A of dish 100 forms tight the contact with thin plate 21p and 22p.Therefore, will not have dust deposit on the 100A of signal record side.In addition, if if manually rotating disc 100 expose side or closure or openness valve 21,22 consciously, then can dispose dust, finger mark or any other bonded to foul on the signal record side 100A of dish 100.
In addition, because valve 21,22 is by latch mechanism 20k locking, so the user can not open valve 21,22 unintentionally.Therefore, can prevent to coil 100 signal record side 100A is stained with dust, finger mark or scraping occur.
In addition, valve 21,22 is respectively arranged with recess 21h and 22h.When valve 21,22 closures, these recesses 21h and 22h contact with each other, and the center pit 100h at dish 100 forms hole 20h just.In this structure, even being placed to the upper side of dish 100, this tray salver 313 exposes up, dust also will pass center pit 100h, and can not be deposited on the valve 21,22.
In addition, shown in Figure 70 and 71, when valve 21,22 is closed, have two pairs at least respectively at chuck and magnetic head opening 11h with face contact portion 21f, 22f and 21g, the 22g of the valve 21,22 that connects above the 11c each other, each all overlaps each other along the thickness direction of dish 100.Therefore, even because the dish 100 with irregular diameter has been installed on this tray salver 313 or because locking fully of valve 21,22, valve 21,22 is not closed fully, can not produce the gap between the contact portion of valve 21,22 yet.Therefore, even in this state, also can prevent to coil and 100 be stained with dust, finger mark or scraping occur.
In addition, shown in Figure 70, valve 21,22 contacts with each other around magnetic head opening 11h, so that the contact portion 22g of valve 22 is positioned at above the contact portion 21g of valve 21.On the other hand, shown in Figure 71, valve 21,22 contacts with each other around chuck opening 11c, so that the contact portion 21f of valve 21 is positioned on the contact portion 22f of valve 22.In this mode, the angle that a plurality of contact portion 21f by valve 21 or 22 or 21g or one of 22f or 22g limit can be different from another angle that is limited by a plurality of contact portion 21f of valve 21 or 22 or 21g or one of 22f or 22g.In this structure, two valve 21,22 can be in the thickness direction closely contact each other of dish 100.Therefore, valve 21 and valve 22 can unconsciously not raise.In addition, when valve 21,22 closures, the contact portion of valve 21,22 can show the rigidity of enhancing.
In this preferred implementation, shown in Figure 70 and 71, valve 21 and valve 22 have contact portion 21f, 21g, 22f and 22g.Yet valve 21 also can have contact portion in different positions with valve 22 and maybe can contact with each other by different modes.For example, can be transformed into around the position of magnetic head opening 11h or at the contact portion 21f shown in Figure 71,22f at the contact portion 21g shown in Figure 70,22g and can be transformed into position around chuck opening 11c.Therefore, when closure, valve 21,22 can show higher rigidity, and can further reduce the gap between the contact portion, thereby prevents that dust from entering tray salver inside.
In addition, when valve 21,22 was closed, two valve block 12f that are provided for upper shell 12 among the projection 21j that is provided for valve 21,22 among Figure 68 and 22j and Figure 65 contacted.Therefore, valve 21,22 forms and is subjected to the rotation of regulation, and can not move from its locked position.As a result, at its locking state, valve 21,22 will can optionally not move.In addition, can prevent user's valve 21,22 that fractures wittingly.In addition, because valve 21,22 forms the rotation that is subjected to regulation, therefore, valve opener/closer 22t can not be offset.Therefore, when putting into this tray salver 313 in the disk drive, valve opener/closer 22t can cooperate with the valve opened/closed mechanism of disk drive as required.
Hereinafter, will illustrate how this tray salver 313 is put in the disk drive.Shown in Figure 66, when with tray salver 313 when direction A injects in the disk drive, the box register pin of disk drive cooperates with the pilot hole 11w of tray salver 313, thus the horizontal and vertical position of the interior tray salver 313 of definite disk drive.
Secondly, shown in Figure 68, the valve opener/closer that is arranged on the valve opened/closed mechanism in the disk drive cooperates with valve opener/closer 22t.Simultaneously, the unlocking element of opened/closed mechanism compresses by elastic part 21e and unclamps part 21y what direction 2A was connected to valve 21.As a result, the locking projection 21k of latch mechanism 20k unclamps its locking mating part 22k, thereby unclamps valve 21,22 each other.In this state, the valve opener of valve opened/closed mechanism/closer is along moving valve opener/closer 22t by arrow 20B indicated direction.Therefore, shown in Figure 67, when control during from elastic force that shutter spring 31 applies, valve 21 rotates on axle 11s.When control during from elastic force that shutter spring 31 applies, with valve 21 synchronized movement, another valve 22 of interlocking by the 20c of interlock mechanism and previous valve 21 also produces rotation.Therefore, when valve 21 has been opened, valve 22 also will be opened.
When valve 21,22 was opened fully, locking projection 21k and locking were unclamped part 21y and will be returned its original position along elastic part 21e.Therefore, the elastic part 21e that is made by resin can not produce plastic yield.In this mode, dish 100 signal record side 100A exposes by chuck and magnetic head opening 11c and 11h.In addition, when valve 21,22 rotations, the dish of clamping by dish folder 21a, 21b, 22a and 22b 100 unclamps.As a result, dish 100 can rotation freely in dish storage compartment 10d.
Then, the spindle motor of disk drive and rotating disk enter chuck opening 11c, and the magnetic head of disk drive enters magnetic head opening 11h.Like this, disk drive is ready to carry out read or write on the dish of putting into 100.
As mentioned above, outside for example only make locking projection 21k by projection, compressing by arrow 20A indicated direction, simultaneously, when unclamping locking mating part 22k when compressing opener/closer 22t by arrow 20B indicated direction, valve 21,22 could rotate to expose chuck and magnetic head opening 11c and 11h, just can unclamp dish folder 21a, 21b, 22a, 22b and coil 100.Therefore, can prevent that the user from opening valve 21,22 unintentionally or shifting out dish 100.As a result, can prevent to coil and 100 be stained with dust, finger mark or scraping occur.
Hereinafter, will illustrate how tray salver 313 ejects from disk drive.When the ejecting mechanism of disk drive begins to operate, self unclamp from valve opener/closer 22t with the valve opener/closer of the disk drive that the valve opener/closer 22t cooperates.As a result, valve 21,22 can not keep opening and beginning along opposite direction rotation.That is to say, valve 21,22 apply from shutter spring 31 and 32 and along this direction with the elastic force effect of closure flap 21,22 under beginning closed itself.As a result, valve 21,22 closure magnetic heads and chuck opening 11h and 11g.In the case, valve 21,22 is locked each other by latch mechanism 20k.Simultaneously, its original position is clamped and returned to dish 100 by dish folder 21a, 21b, 22a, 22b.Then, tray salver 313 ejects from disk drive.
Shown in Figure 69, in tray salver 313, be provided for the dish contact portion 23a of dish folder 23 of box body 10 and the dish contact portion 12s ' of upper shell 12 and be positioned on the same vertical plane.In addition, inclined-plane 21a ', the 21b ' of the dish of valve 21,22 folder 21a, 21b, 22a, 22b, the top of 22a ', 22b ' are along on the dish 100 direction 100u that move, and be higher on surface level than the bottom of dish contact portion 23a and 12s '.Therefore, even tray salver 313 vertical or inversion threading disk drives, valve 21,22 also can be clamped dish 100 thereon securely.For example, put into disk drives, then do not reclamp with coiling contact portion 23a and contact with 12s ' to clamp and coil 100, still can keep its horizontal level if tray salver 313 is inverted.And when valve 21,22 with this state during at closure state, at this moment, dish 100 contacts with inclined-plane 21a ', 21b ', 22a ' and 22b '.Then, dish 100 along inclined-plane 21a ', 21b ', 22a ' and 22b ' slides reposefully and by dish press from both sides 21a, 21b, 22a, 22b firmly clamp.
In the tray salver of above-mentioned the 13 preferred implementation, its box body has a side of a dish window and a covering disk.In addition, tray salver is included in the valve opener/closer in the box body magnetic head opening, and therefore, not needing provides unnecessary gap for box body.As a result, not having dust enters in the box body.
In addition, in the tray salver of this 13 preferred implementation, the line that two valve are made as the center line of the dish above the chuck opening and are defined as predetermined angle with center line above the magnetic head opening contacts with each other.Therefore, these valve have the one-piece construction of close valve opener/closer and demonstrate sufficiently high rigidity.
In addition, because two valve can lock or unclamp each other, the user is the closure or openness valve unintentionally.Therefore, can prevent that dish is stained with dust, finger mark or scraping occur.
In addition, in a plurality of dish folders of tray salver is not to be fixed on its corresponding valve at least, but connects by elastic part.When being applied to this dish folder and going up as the elastic force with shutter spring, elastic deformation radially takes place in what the dish folder will be along dish fully.For this reason, even the dish of non-regular size has been installed on this tray salver, tray salver also can be clamped this dish securely and it is optionally moved.

Hereinafter, specify according to the tray salver 314 in this aspect the 14 concrete preferred implementation with reference to Figure 72 to 81.In Figure 81, the 14 concrete preferred implementation tray salver 314 each parts that have basic said function with the corresponding component of above-mentioned the 13 preferred implementation tray salver 313 are represented with same label at Figure 72
The tray salver 314 of the 14 preferred implementation is at the tray salver 313 that is different from above-mentioned the 13 preferred implementation separately in shape of interior upper surface 12u, dish folder 21a, 21b, 22a, 22b (referring to Figure 72 to 79) and the dish block 53 (referring to Figure 72,77 and 78) of box body 10 (referring to Figure 79).In addition, tray salver 314 also comprises dish support section 60 (referring to Figure 72 and 81).Therefore, will concentrate in these areas difference to the explanation of the tray salver 314 of the present invention's the 14 preferred implementation.
In the tray salver 313 of above-mentioned the 13 preferred implementation, the top separately of dish folder 21a, 21b, 22a and 22b is positioned at substantially along on the same vertical plane of the excircle of dish 100.On the contrary, in the tray salver 314 of the 14 preferred implementation, shown in Figure 73 and 79, projection is formed at the presumptive area of dish folder 21b, 22a and 22b.More particularly, shown in Figure 79, each of these three dish folders 21b, 22a and 22b all comprises: have projection thereon and have the 121b of first, 122a or the 122b of the first height h1 that measures from the upper surface of valve 21,22; And second portion 221b, 222a or 222b with the second height h2 that measures from the upper surface of valve 21,22.Another dish folder 21a is made up of the second portion 221a with second height h2.
The first height h1 is greater than the second height h2 and be approximately equal to the height (that is the vertical height of upper surface) of dish folder 21a, 21b, 22a and the 22b of above-mentioned the 13 preferred implementation tray salver 313.That is to say that except that the 121b of its first, 122a and 122b, the dish of this 14 preferred implementation folder 21a, 21b, 22a and 22b are lower than the 13 preferred implementation tray salver 313 corresponding components.
In addition, shown in Figure 74 and 75, ladder projection 223 is formed at the upper surface of the 122a of first of dish folder 22a.Ladder projection 223 has two vertical planes, near the higher level of shaft collar 100.Similar ladder projection also is formed on the upper surface of the upper surface of the 121b of first that coils folder 21b and the 122b of first that dish presss from both sides 22b.
When valve 21 or 22 will be closed, the 121b of first, the 122a of dish folder 21b, 22a and 22b and 122b early than any other parts with coil 100 and contact (that is, Zao) than its second portion 221b, 222a or 222b.
When valve 21,22 closure or openness, dish folder 21a, 21b, 22a and 22b move.Figure 77 shows the position separately of opening hour indicator folder 21a, 21b, 22a and 22b when valve 21,22.On the other hand, Figure 78 shows the position separately as valve 21,22 closed hour indicator folder 21a, 21b, 22a and 22b.Figure 79 and 80 is demonstration sectional views along the part of the tray salver 314 of B-B of profile line separately shown in Figure 78 and C-C intercepting.
Shown in Figure 77,78 and 79, when valve 21 or 22 closures, regional 12y, 12x and 12z in the box body 10 on the upper surface 12u are recessed, and the 121b of first, the 122a of its mid-game folder 21b, 22a and 22b and 122b pass.On the other hand, to pass wherein regional 12y ', 12x ' and 12z ' be not recessed for second portion 221b, 222a or 222b.Therefore, regional 12y, 12x and 12z are more thinner than regional 12y ', 12x ' and 12z ' in the upper shell 12.
Shown in Figure 76 and 79, the position of top on perpendicular of the 122a of first of dish folder 22a is higher than the bottom of coiling block 53.In addition, upper surface 12u went up recessed first area 12x in the top of the 122a of first of dish folder 22a was contained in.Because ladder projection 223 is formed at the top of the 122a of first, so just a part of upper surface of the 122a of first contacts with interior upper surface 12u.On the other hand, the second portion 222a of dish folder 22a does not contact with interior upper surface 12u.
In order to open reposefully and closure flap 21, in optimal way, the top and the friction that the contact between the interior upper surface 12u causes of the 122a of first of pressing from both sides 22a by dish is very little.For this reason, when radially intercepting at dish 100, the cross section that the top of the 122a of first of dish folder 22a has circular arc.This ladder projection 223 is set to compensate because the defective of the physical strength aspect that the pinnacle of the 122a of first causes, and makes the mold pressing at this top more accurate and more convenient.
Shown in Figure 80, the position of top on vertical plane of the 122b of first of dish folder 22b is higher than the bottom of coiling block 53.And the top of the 122b of first of dish folder 22b is contained in the recessed first area 12z on the interior upper surface 12u.Though not shown, the position of top on vertical plane of the 121b of first of dish folder 22b also is higher than the bottom of coiling block 53, and the recessed first area 12y on the upper surface 12u in being contained in.
As mentioned above, in the tray salver 314 of the 14 preferred implementation, regional 12y, 12x on the interior upper surface 12u and 12z are recessed with difference holding portion dish folder 22a, 21b and 22b.Therefore, can pass through the degree of depth of these recessed regions 12y, 12x and 12z to reduce the thickness of tray salver 314.
Shown in Figure 79, when valve 21,22 closures, even have the tray salver 314 vertical or inversion threading disk drives of this structure, the dish 100 that does not reclamp can contact with the inclined-plane 122a ' that coils the 122a of first that presss from both sides 22a at all.After this, dish 100 will contact (referring to Figure 74) with the inclined-plane 222a ' with the second portion 222a that coils folder 22a along inclined-plane 122a ' smooth sliding.Simultaneously, dish 100 also contacts with the inclined-plane 221a ' of the second portion 221a that coils folder 21a.In this mode, dish folder 21a and 22a will coil 100 and clamp together thereon.Two other dish folder 21b and 22b also clamp dish 100 thereon by same operation.Therefore, though this tray salver 314 can have the thickness of attenuate, tray salver 314 closure flap 21,22 is at an arbitrary position also clamped dish 100 thereon as required.
If this tray salver just has the thickness of its attenuate, and the shape of the change dish folder dish folder of the 13 preferred implementation (or use when it changes) is not coiled on interior upper surface 12u and is pressed from both sides regional 12x, 12x ', 12y, 12y ', 12z and the 12z ' that 21a, 21b and 22a pass wherein and see that from Figure 78 all should be recessed.In the case, upper shell 12 should have the thickness of attenuate in quite wide regional extent, and this tray salver should have the physical strength of reduction.On the contrary, because regional 12x, the 12y of thickness thinning and 12z relative narrower, therefore the tray salver 314 of the 14 preferred implementation can have the thickness of attenuate but can not reduce its physical strength.
In above-mentioned preferred implementation, three projections are provided for four three of coiling in the folder.Yet the number of the projection of setting can change according to the number of dish folder or the shape of valve.
The tray salver 314 of the 14 preferred implementation is at the tray salver 313 that is different from the 13 preferred implementation in shape of dish block 53.
Shown in Figure 72, dish block 53 has the shape of recess circular slab.Specifically, the recess 54 that has a basic same shape with dish block 53 is provided with along the dish window 12w of upper shell 12, and dish block 53 cooperates in rotation status formation with recess 54.Shown in Figure 77, dish block 53 is clamped in this way, protrudes partly when rotating with box lunch in the dish window 12w of upper shell 12 into.In addition, shown in Figure 78,, also can clamp dish block 53 so that be stored in the upper shell 12 and can not protrude among the dish window 12w by rotating disc block 53.For example, can arbitrarily unclamp recess 54 easily, then coil the side surface of block 53 and the recess 54 of upper shell 12 and can have the recessed and projection that is fitted to each other as fruit tray block 53.
In this structure, the thickness of dish block 53 equals the thickness on upper shell 12 tops substantially.Therefore, can reduce the whole thickness of tray salver 314.
The tray salver 314 of the 14 preferred implementation is characterised in that in the bottom of dish storage compartment and comprises dish support section 60.Shown in Figure 72,77,78 and 81, dish support section 60 is between the interior lower surface 11u and inner surface 11i of box body 10.Shown in Figure 81, dish support section 60 has the upper surface 60a of the interior lower surface 11u that is parallel to box body 10.
Equally shown in Figure 81, closed and coil 100 when clamping by dish when valve 21,22, the outward flange of the signal record side 100A of dish 100 contacts with the upper surface 60a that coils support section 60 with its peripheral part.Therefore, coiling 100 signal record side 100A or accumulating on the interior lower surface 11u of box body 10 not having dust deposit.
Mode as an alternative, dish support section 60 can have and not be the arbitrary shape shown in Figure 81.For example, shown in Figure 82, having upwards, the dish support section 76 of tapered cross-section shape can be formed between the interior lower surface 11u and inner surface 11i of box body 10.In the case, closed and coil 100 when clamping when valve 21,22 by dish, the outward flange of the signal record side 100A of dish 100 with coil support section 76 and contact.
Embodiment 15
Hereinafter, specify tray salver 315 with reference to Figure 83 to 87 according to this aspect the 15 concrete preferred implementation., in Figure 87, have with each parts of the 15 concrete preferred implementation tray salver 315 of the basic said function of tray salver 314 corresponding components of above-mentioned the 14 preferred implementation and represent at Figure 83 with same label.
Shown in Figure 83, different with the tray salver 314 of above-mentioned the 14 preferred implementation, the tray salver 315 of the 15 preferred implementation comprises that the recess 85,86,87 of four kinds of forms and 88a are to 88c.Recess 85 is formed at the 21v of lower surface separately and the 22v of valve 21,22.The recess 86,87 of other three kinds of forms and 88a are formed at the interior lower surface 11u of the box body 10 that contacts with valve 21,22 to 88c.The recess of these four kinds of forms is with explanation successively below.For example, suppose that tray salver 315 clamps and have the dish that diameter is approximately 12cm, then these recesses can have the degree of depth of about 0.1mm to 0.3mm.
Figure 84 and 85 shows that its valve 21,22 is opened respectively and the tray salver 315 of closed two states, when valve 21,22 was opened and be closed, the recess 86 of first kind of form was formed at regional separately with dish folder 21a, the 21b of valve 21,22, interior lower surface 11u that 22a contact with 22b.
Dish folder 21a, 21b, 22a and 22b are clipped between the upper and lower casing almost very close to each other therebetween 12,11.Therefore, if when each parts with tray salver 315 be assembled together or these parts of tray salver 315 in any one when having size with member the size of big-difference being arranged very much, dish folder 21a, 21b, 22a can contact with upper and lower casing 12,11 with 22b.In this case, will dish folder 21a, 21b, 22a and 22b and on or produce excessive friction between lower house 12 or 11.As a result, the convenience like this that valve 21,22 can not closure or openness or because excessive friction evokes dust.
But,, below 21a, 21b, 22a and 22b, form at interval the friction that can reduce not expect like this by the recess 86 that first kind of form is set.Thus, valve 21 and 22 opening and closing smoothly always, and can not evoke dust because of the friction reason.
When valve 21 and 22 when closed, the recess 87 of second kind of form is formed at these zones of interior lower surface 11u of the outer edge separately of valve 21,22 location.Shown in Figure 84 and 86, in optimal way, these recesses 87 are gone up along interior lower surface 11u and are limited valve 21,22 outer peripheral borders extensions, and are present in the inboard and the outside on border in optimal way.
In Figure 86, suppose that this tray salver 315 dishes 100 are stored in wherein, and a side exposes, the user can be along by arrow A indicated direction compression plate 100.For the signal record side 100A of protective disc 100, the upper surface separately of valve 21,22 is coated with non-woven fibre 21s and 22s, but its outward flange is not to be coated with non-woven fibre 21s and 22s fully.Therefore, shown in Figure 86, if at arrow A indicated direction compression plate 100, then the outward flange of valve 21,22 contacts with the signal record side 100A of dish 100, and signal record side 100A therefore may swipe.
Yet if the recess 87 of second kind of form is set, valve 21,22 may be out of shape in the following manner, and its outward flange is compressed into the recess 87 of second kind of form partly.Like this, snap-in force is disperseed, and the outward flange of valve 21,22 will be not the signal record side 100A of compression plate 100 very closely.
The recess of the third form comprises: in being formed on the lower surface 11u, so that around the recess 88a of chuck and magnetic head opening 11c and 11h; Be formed at these regional recess 88b that when valve 21,22 closures, can not pass through the interior lower surface 11u of valve 21,22 overlap joints; And when valve 21,22 closures, be arranged in the recess 88c in the zone of the lower surface 11u that overlaps by valve 21,22.Recess 88b and recess 88c are arranged to so that round along the circumference picture of dish storage compartment 10d, and the number of the recess 88a of the third form is three.
This tray salver 315 is provided with and is used to prevent that dust from entering tray salver 315 or being deposited on the various forms of structures (for example, dish support section) of the signal record side 100A of dish 100.Yet, in fact be difficult to eliminate fully entering tray salver 315 or being deposited on dust on the signal record side 100A of dish 100.
Therefore, recess 88a, the 88b of the third form and 88c are arranged for the dust that collection has entered tray salver 315.Specifically, when valve 21,22 closure or openness, dust is collected among these recesses 88a, the 88b and 88c of the third form.In case be collected among recess 88a, 88b and the 88c, dust can not contact valve 21,22 and be retained among recess 88a, 88b and the 88c, and can not fly out recess 88a, 88b and 88c.Therefore, in this mode, by dust being collected among recess 88a, 88b and the 88c, dust will can not interfere valve 21,22 closure or openness or since excessive friction evoked.
Should be noted that these effects can reach by the recess 86 of first kind of form or the recess 87 of second kind of form.Therefore, tray salver 315 needn't comprise the form of ownership of these recesses 86,87,88a, 88b and 88c, but also can include only a kind of recess of form.Even so, valve 21,22 will be not yet can be owing to dust be interfered its unlatching and closure, and can be owing to friction evokes dust.
In addition, be collected in the recess 87 of second kind of form for the dust of removing gap between valve 21,22 and the interior lower surface 11u and with it, for example, even more effective, the 21v of lower surface separately of valve 21,22 and 22v can be provided with recess 85 along its outward flange.Shown in Figure 84, in this case, when valve 21,22 closures, these recesses 85 are preferably placed in the recess 87 (that is the position of the center line of more close tray salver 315) of second kind of form.In addition, shown in Figure 86, when valve 21,22 closures, the recess 85 of valve 21,22 is preferred discontinuous with the recess 87 of second kind of form on interior lower surface 11u.
When valve 21,22 had recess 85, the outward flange of valve 21,22 is easy deformation more.Therefore, even be applied to dish 100 at direction A when external force, the outward flange of valve 21,22 is easy deformation more also, and will be still less possibly the signal record side 100A of compression plate 100 to swipe it.Selectively, these recesses 86,87,88a, 88b and 88c within it face be coated with bonding or weld non-woven fibre on it.Like this, the gap that is produced in box body by these recesses obtains filling, and dust will can not enter this tray salver 315 at an easy rate.
In above-mentioned the 15 preferred implementation, various forms of recesses are provided for the 14 preferred implementation.On the other hand, these recesses also can be provided for according to any one tray salver of the invention described above the 8th to the 13 preferred implementation.
Embodiment 16
Hereinafter, be specifically described with reference to Figure 88 to 93 pair of tray salver 316 according to this aspect the 16 concrete preferred implementation., in Figure 93, have each parts that tray salver 313 corresponding components with above-mentioned the 13 preferred implementation have the 16 a concrete preferred implementation tray salver 316 of basic said function and represent at Figure 88 with same label.
Shown in Figure 88, the tray salver 316 of this preferred implementation comprises respectively at first and second side surface 10p of box body 10 and the first and second openers/closer 22t and 93 on the 10q.First opener/closer 22t is formed on the first side surface 10p of the direction A extension that is basically perpendicular to these tray salver 316 reeve disk drives, and two openers/closer 93 is formed on the second side surface 10q that is basically parallel to direction A extension.First opener/closer 22t has the valve opener/same structure of closer 22t with the tray salver 313 of the 13 preferred implementation.
Shown in Figure 89, second opener/closer 93 forms the shape of the gear with the hole that can inject the axle 11q that is provided for lower house 11.When second opener/when closer 93 injected axle 11q, the side surface of lower house 11 had opening 11r to expose the part of second opener/closer 93 by the second side surface 10q of box body 10.On the other hand, upper shell 12 can be provided with a 11q.
Valve 21,22 also is arranged to expose or cover magnetic head and the chuck opening 11h and the 11o of lower house 11. Valve 21,22 is equal to first, second valve that defines in claims.First opener/closer 22t forms the global facility of valve 22.On the other hand, the sector gear 21m that cooperates with second opener/closer 93 is formed at the outer surface of valve 21 and is positioned at the position that presss from both sides 21b near dish.The rotation center of sector gear 21m is the axis hole 21u of valve 21.The outer surface of valve 21 also has the recess 21n that closes on sector gear 21m.This recess 21n is arranged to limit the space that second opener/closer 93 cooperates with sector gear 21m.
Utilize first opener/closer 22t can pass through following manner closure or openness valve 21,22.At first, shown in Figure 90, the locking projection 21k and the locking mating part 22k that form latch mechanism 20k together unclamp each other.Then, first opener/closer 22t slides along the first slidingsurface 10p by the box body 10 of arrow 22w indication among Figure 90.As a result, shown in Figure 91, other valve 21 is by interlock 20c and valve 22 same moved further, and these two valve 21,22 expose magnetic head and chuck opening 11h and 11c.
Utilize second opener/closer 93 also can open valve 21,22 by following manner.At first, shown in Figure 90, latch mechanism 20k unclamps.Then, second opener/closer 93 rotates to arrow 93A indicated direction.Then, sector gear 21m cooperates and begins with second opener/closer 93 and rotates on axis hole 21u, thereby opens valve 21.Because also by interlock 20c and valve 21 same moved further, these two valve 21,22 expose magnetic head and chuck opening 11h and 11c to another valve 22.Shown in Figure 91, when magnetic head and chuck opening 11h and 11c exposed fully by valve 21,22, the part of second opener/closer 93 was positioned at the recess 21n of valve 21.
For closure flap 21,22, the first openers/closer 22t can be along sliding with the reverse direction of direction 22w or second opener/closer 93 can rotate to the direction opposite with direction 93A.In this preferred implementation, tray salver 316 comprises and elastic force being applied on the valve 21,22 and along the shutter spring 31 and 32 of this direction closure flap 21,22.Therefore, unless have the enough strong acting force that overcomes shutter spring 31 and 32 elastic force be applied to first or second opener/closer 22t or 93 to open valve 21,22 or to make valve 21,22 be held open state, then valve 21,22 will be automatically closed itself.
In the tray salver 316 of the 16 preferred implementation, opener/closer is arranged on the valve 21,22 to inject the side surface of disk drive directions and to be parallel to tray salver perpendicular to this tray salver 316 and injects on the direction side surface.Therefore, the disk drive that no matter uses be only with comprise along the tray salver compatibility of the valve opener/closer on the side surface that extends perpendicular to the tray salver direction of insertion, still only be included in the tray salver compatibility that is parallel to the valve opener/closer on the side surface that the tray salver direction of insertion extends, disk drive always can read or write the signal on the dish in the tray salver that is stored in this optimal way.
In addition, in the tray salver 316 of this 16 preferred implementation, the second opener/closer 93 that is provided for being parallel to tray salver 316 direction of insertion side surfaces has gear shape.Therefore, the mechanism that is provided for the valve opened/closed of disk drive also can be any kind shape and gear that second opener/closer 93 cooperates.Therefore, disk drive can use the valve 21,22 of simple relatively structure with closure or openness tray salver 316.
In above-mentioned preferred implementation, sector gear 21m is arranged near dish folder 21b.This is because the distance between the axis hole 21u of the sector gear 21m of this position and valve 21 is short relatively, and removes complete opening valve 21 because sector gear 21m need have short relatively length.Yet sector gear 21m must be arranged on this position.On the other hand, the sector gear 21m and second opener/closer 93 also can be arranged on the position shown in Figure 92 and 93.In another preferred implementation shown in Figure 92 and 93, when extending, sector gear 21m can be arranged on this position, the circular trace of being drawn by sector gear 21m intersects basic center with dish 100, and second opener/closer 93 can be provided with following position so that cooperate with sector gear 21m.When second opener/when closer 93 is arranged on this position, sector gear 21m should be relatively long with complete opening valve 21, but the distance between sector gear 21m and the axis hole 21u also can be longer relatively.That is to say, in this case,, therefore, only need less power promptly can rotate second opener/closer 93 owing between fulcrum and application point, have long distance, thus closure or openness valve 21,22.
Embodiment 17
Hereinafter, be specifically described with reference to Figure 94 to 97 pair of tray salver 317 according to this aspect the 17 concrete preferred implementation., in Figure 97, have each parts that tray salver 316 corresponding components with above-mentioned the 16 preferred implementation have the 17 a concrete preferred implementation tray salver 317 of basic said function and represent at Figure 94 with same label.

Hereinafter, be specifically described with reference to Figure 98 to 101 pair of tray salver 318 according to this aspect the 18 concrete preferred implementation., in Figure 101, have each parts that tray salver 316 corresponding components with above-mentioned the 16 preferred implementation have the 18 a concrete preferred implementation tray salver 318 of basic said function and represent at Figure 98 with same label.
Shown in Figure 98, the tray salver 318 of this 18 preferred implementation is included in the second opener/closer 96 on its second side surface 10q, rather than second opener of the tray salver 316 of above-mentioned the 16 preferred implementation/closer 93.
From Figure 99 as can be seen, second opener/closer 96 presss from both sides the band spare of 21a for the dish that is connected to valve 21.These band part 96 one ends have projection 96a.And projection 96a can slide along the opening 11r of lower house 11.Mode as an alternative, second opener/closer 96 can form the global facility of valve 21.
Figure 100 and 101 shows the two states of the tray salver 318 in valve 21,22 difference closures and the unlatching.The the 16 and the 17 preferred implementation as already explained, valve 21,22 can be by sliding first opener/closer 22t to carry out closure or openness along direction 22w or along opposite direction.
Valve 21,22 also can use second opener/closer 96 to realize unlatching in the following manner.At first, latch mechanism 20k unclamps shown in Figure 100.Then, second opener/closer 96 slides along the direction shown in the arrow 96b.The result of this operation is that power is applied to valve 21 along following direction, so that rotate the end of valve 21 on axis hole 21u, that is, rotates to arrow 96c indicated direction.Because also by latch mechanism 20c and valve 21 same moved further, these two valve 21,22 expose magnetic head and chuck opening 11h and 11c to another valve 22.For the projection 96a of closure flap 21,22, the second openers/closer 96 can be along opposite direction slip.
Tray salver 316 as above-mentioned the 16 preferred implementation, the disk drive that no matter uses is only to mate with the tray salver that is included in the valve opener/closer on the side surface that extends perpendicular to the tray salver direction of insertion, still only be included in the tray salver coupling that is parallel to the valve opener/closer on the side surface that the tray salver direction of insertion extends, disk drive always can read or write the signal on the dish in the tray salver that is stored in this optimal way.
If second opener/closer 96 forms the global facility of valve 21, can reduce the part count that constitutes tray salver 318.As a result, tray salver can or be simplified manufacture process with lower cost manufacturing.
In the 16 to the 18 preferred implementation of the invention described above, second opener/closer is arranged on the left side of relative tray salver direction of insertion.But second opener/closer is not limited only to above-mentioned leftward position.Mode as an alternative, shown in Figure 88, second opener/closer also can be arranged on the right side 10r of relative tray salver direction of insertion.In another alternative, second opener/closer also can be arranged on the rear side 10t of relative tray salver 316 direction of insertion.In the case,, and do not need to change its local aspect because tray salver 318 can have the projection 96a of the second opener/closer on its rear side, so, the band shape of this 18 preferred implementation preferably used.
Embodiment 19
Hereinafter, be specifically described with reference to Figure 102 and 103 pairs of tray salvers 319 according to this aspect the 19 concrete preferred implementation., in Figure 103, have each parts that tray salver 313 corresponding components with above-mentioned the 13 preferred implementation have the 19 a concrete preferred implementation tray salver 319 of basic said function and represent at Figure 102 with same label.
The tray salver 319 of this preferred implementation is characterised in that the recess 89 that coils folder 21b, 22a and 22b and be used for valve 21,22 by being provided for respectively.Recess 89 adopts ultrasound wave that non-woven fibre is welded on the valve 21,22 usually.
More particularly, dish folder 21b, 22a and 22b comprise hole 21q, 22r and the 22q that cooperates with rotary block 97.Shown in Figure 103, when dish 100 was clamped by dish folder 21b, 21a, 22a and 22b, rotary block 97 protruded with 22b ' part and contacts with the outward flange that coils 100 from inclined-plane 12b ', the 22a ' of dish folder 21b, 22a and 22b.Rotary block 97 is preferably made by resilient material with big friction factor such as rubber.
Should be noted that dish folder one of 21b, 21a, 22a and 22b should comprise that rotary block 97 is to brake the rotation of unwanted dish 100 fully at least.Yet in order to prevent to coil 100 random rotation more definitely, three rotary blocks 97 preferably are set to shown in Figure 102.
In this structure, when dish 100 was clamped by dish folder 21b, 21a, 22a and 22b, the rotary block 97 that closely contacts with dish 100 did not allow user's rotating disc 100 easily.Therefore, in this state,,, then coil 100 and also can easily not rotate even if the user attempts rotating disc 100 wittingly when coiling 100 when compressing valve 21,22.Therefore, even if hard relatively dust has adhered on the non-woven fibre that covers valve 21,22, because the random rotating disc 100 of user, coiling 100 can be owing to dust is swiped yet.
In addition, by rotary block 97 is set, can prevents to coil 100 and in the dish storage compartment, arbitrarily move.
Shown in Figure 102, valve 21,22 comprises that non-woven fibre is by being ultrasonically bonded to the recess 89 that covers the valve surface that contacts with the signal record side 100A of dish 100 on it with part.In the preferred implementation shown in Figure 102, recess 89 forms so that the excircle of valve 21,22 these parts that contact around the signal record side 100A with dish 100.Recess 89 also is formed at the inside of excircle.Yet as long as non-woven fibre can bond to valve 21,22 as required, recess 89 also can be formed on these zones shown in any zone rather than Figure 102.At these recess 89 places, non-woven fibre can be with being ultrasonically bonded to valve 21,22.When being ultrasonically bonded to valve 21,22, non-woven fibre can solidify partly or the resin material of valve 21,22 can protrude from non-woven fibre partly.Even so, the part of these curing or protrusion is held by recess 89 and signal record side 100A that can scraping dish 100.When non-woven fibre was connected to valve 21,22, these recesses 89 were preferably formed on according to the valve in any tray salver of the invention described above the first to the 18 preferred implementation 21,22.
Embodiment 20
Hereinafter, with reference to corresponding accompanying drawing the tray salver 320 according to this aspect the 20 concrete preferred implementation is specifically described.
At first, with reference to Figure 104 the total of tray salver 320 is carried out summary description.Tray salver 320 comprises lower house 11, upper shell 12, first valve 21, second valve 22, dish block 23, protector 24 and revolving part 25.These parts can be made by for example synthetic resin.Yet, when unnecessary these all parts are all adopted same material.Replace, from the requirement of the angle of physical strength or its outward appearance, can select best material to be used to make these parts.
Shown in Figure 104, box body 10 has interior lower surface 11u.Interior lower surface 11u has chuck opening 11c and magnetic head opening 11h.Chuck opening 11c allows chuck spare (spindle motor that for example, is used for rotating disc 100) to enter tray salver 320 from the outside.Magnetic head opening 11h allow from/read and/or the magnetic head of write signal enters tray salver 320 and reaches the target location at dish 100 at the signal record side 100A of dish 100.Magnetic head opening 11h and chuck opening 11c are continuously and be extended to a side surface of lower house 11.In addition, another opening 11r is arranged on the opposite side surface of lower house 11 with the side surface adjacency with magnetic head opening 11h.
As the situation that will specify in the back, interior lower surface 11u has the groove 11e and the 11f of end separately of two projection 25e that hold to be provided for revolving part 25 and 25f.The bottom of lower surface 11u in these grooves 11e and 11f preferably do not arrive.Interior lower surface 11u also comprises the axis hole 39 that holds the axle 37 and 38 that is provided for first, second valve 21,22 respectively.The bottom of lower surface 11u in these axis holes 39 preferably do not arrive yet.In the preferred implementation shown in Figure 104, axle 37 and 38 is formed at first, second valve 21,22, and axis hole 39 is formed on the lower house 11.On the other hand, axis hole also can be formed at first, second valve 21,22 and the axle be formed on the lower house 11.
Lower house 11 also comprises the pilot hole 11w that the box register pin of two disk drives can inject.
Upper shell 12 is included in the circular discs window 12w that extends on the whole raised zones of dish 100.Dish window 12w limits by the circular inner surface 12i of box body 10.Dish 100 can inject tray salver 320 by this dish window 12w.Inner surface 12i has recess 12g.
The upper surface 12d of upper shell 12 also has the recess 12j that cooperates with dish block 23.Though not shown, the upper surface 12d of dish block 23 and upper shell 12 is provided with the recessed/projection that is fitted to each other, so that dish block 23 can so easily not make himself and upper shell 12 unclamp.When dish block 23 cooperated with upper shell 12, the part of dish block 23 was protruded into dish window 12w.In this preferred implementation, in order to reduce the whole thickness of box body as much as possible, recess 12j is formed by a part of removing upper shell 12 fully.Yet if tray salver has the thickness that is a bit larger tham demonstration, recess also can form, rather than the part by removing upper shell 12 fully to be to form recess 12j, the dish block that also can prefabricated and such recess cooperates.For example, the recess of the tray salver 308 of above-mentioned the 8th preferred implementation and dish block 23 can be provided for the tray salver 320 of the 20 preferred implementation.
Another dish block 21s is set to the global facility of upper shell 12, advances window 12w so that extend.Dish block 21s and 23 is used to prevent that the dish of fixing 100 from falling by dish window 12w at first, second valve 21,22 open periods and at first, second valve 21,22 periods of contact.When this tray salver 320 was put in the disk drive of vertical fixing, these dishes block 12s and 23 was very effective.For removal dish 100 in the tray salver 320 from then on, dish block 23 need be unclamped and shift out, and dish 100 need be taken out near recess 12j from upper shell 12.As selection mode, three or more dish blocks and/or each dish block can be set can or be arranged on any position with any other shape formation, rather than the position shown in Figure 104.
Upper and lower casing is 12,11 bonding with its excircle, welding or is connected (for example, bolt connects) together, thus formation box body 10.In addition, the interior lower surface 11u of box body 10 and inner surface 12i form together and are used for the dish storage compartment of storage disks 100 therein.
In the dish storage compartment, enough wide in the space that limits by inner surface 12i is so that permission dish 100 rotates freely therein and do not contact with inner surface 12i.The top of open disk storage compartment is as dish window 12w, and the first side 100B that is stored in the dish 100 of dish storage compartment exposes fully in dish window 12w.On the other hand, second side, that is, the signal record side 100A of dish 100 is in the face of interior lower surface 11u.
By adopting this structure, tray salver 320 can be more thinner than the conventional cartridge of covering disk two sides.In addition, the content that the label side of dish 100 may be displayed in the dish window 12w and the user can check the dish 100 that is printed on label side (that is first side) 100B.In addition, by the content of show tags side, comprise that the tray salver of dish also has structure preferably.
First, second valve 21,22 is arranged on the interior lower surface 11u of box body 10.When dish 100 was stored in the tray salver 320, first, second valve 21,22 was positioned between signal record side (that is second the side) 100A and interior lower surface 11u of dish 100.First, second valve 21,22 has the axle 37 and 38 of the axis hole 39 that injects lower house 11 respectively.Therefore, first, second valve 21,22 rotates on axle 37,38, thereby covers or expose magnetic head and chuck opening 11h, 11c.When first, second valve 21,22 was opened, the second side 100A of dish 100 was exposed in the chuck opening 11h partly.
First, second valve 21,22 is provided with recess, with first, second valve of box lunch 21,22 when closed limiting hole 20h with the zone of the center pit 100h overlap joint that is stored in the dish 100 in the dish storage compartment in.The recess of first, second valve 21,22 is respectively around projection 21w, 22w.When first, second valve 21,22 closures, these projections 21w, 22w be closely contact each other, thus the annulus 20w of the inner periphery of the center pit 100h of formation abuts tray 100.
In addition, clamp at the dish storage compartment in order to coil 100 simultaneously at closed first, second valve 21,22, first valve 21 comprises dish folder 21b, and second valve 22 comprises dish folder 22a and 22b.These dish folders 21b, 22a press from both sides the same operation with 22b with the above-mentioned described dish of the 8th to the 19 preferred implementation that is used for.In the 8th to the 19 preferred implementation, first valve 21 also comprises dish folder 21a.And in this 20 preferred implementation, first valve 21 comprises projection 27a, rather than dish folder 21a.When first, second valve 21,22 was closed, the chuck opening 11h that projection 27a is arranged to prevent to coil 100 a side surface side surface by arriving lower house 11 exposed.
When closure, first, second valve 21,22 is not to contact with each other fully along the line, but has many contact portions of not aliging with line.More particularly, valve 21,22 has first couple of contact portion 21f and 22f and the second couple of contact portion 21g and 22g.In this preferred implementation, contact portion 21f and 22f almost contact with each other along the center line of tray salver 320.On the other hand, contact portion 21g and 22g contact with each other along the line that the center line with tray salver 320 limits predetermined angle (for example, about 15 ° to about 18 °).The effect that realizes by this structure specifies in the 13 preferred implementation.As the 13 preferred implementation that has illustrated, contact portion 21g and 22g are along the local each other overlap joint of the thickness direction of dish 100.
The back will be specifically described, and first, second valve 21,22 comprises gathering sill 27e and the 28f that cooperates with the projection 25e and the 25f of revolving part 25 respectively.Gathering sill 27e passes through first, second valve 21,22 vertical extensions respectively with 28f, so that the projection 25e of revolving part 25 and 25f can distinguish arrival slot 11e and 11f.
Revolving part 25 comprises sidewall 25i and is connected to the dish support section 25a of sidewall 25i bottom.Sidewall 25i has cylindrical shape and the following size of tool, so that around the side surface that is stored in the dish 100 in the dish storage compartment.Sidewall 25i is separated by three groove 25d, 25g and 25h.Dish support section 25a is the flat annular shape that comprises groove 25c.When first, second valve 21,22 is opened, revolving part 25 rotations, thus make groove 25c and magnetic head opening 11h overlap joint.The projection 25m that is used for mobile protector 24 is arranged near groove 25d.
As mentioned above, protrude the lower surface that is arranged on dish support section 25a to the projection 25e and the 25f of lower house 11.In addition, the opener/closer 25j that cooperates with the valve opened/closed mechanism of disk drive is arranged on the outer surface of sidewall 25i.Mode as an alternative, the valve opened/closed mechanism of disk drive is gear shape, and gear can be arranged on the outer surface of sidewall 25i, rather than on opener/closer 25j.
Protector 24 is arranged in the groove 12g of inner surface 12i of box body 10.The structure of protector 24 and operation will be specifically described below.
The corresponding component that assembles tray salver 320 in this way is to satisfy the vertical positional relationship shown in Figure 104.As a result, upper and lower housing 11,12 links together, so that first, second valve 21,22 is arranged on the lower house 11, and revolving part 25 is positioned on the valve 21,22.
Figure 105 is a front view of removing the tray salver 320 of upper shell 12.Figure 106 shows the sectional view of analysing and observe along F-F along the line among Figure 105.First, second valve 21,22 closures among the figure.
Shown in Figure 105, the dish of second valve 22 folder 22a clamps dish 100 in the groove 25d of revolving part 25.The dish 100 also dish folder 21b and the 22b of the groove 25d by laying respectively at revolving part 25 and first, second valve 21,22 in the 25h is fixed.
The opener of revolving part 25/closer 25j is positioned at lower house 11 opening 11r.The projection 35,36 of first, second valve 21,22 protrudes among the center pit 100h of dish 100.The basic center-aligned with dish 100 of the rotation center of revolving part 25.That is to say that revolving part 25 is arranged in the dish storage compartment, so that the rotation of the center of basic drum 100.
The axle 37,38 of first, second valve 21,22 is positioned at below the dish support part of revolving part 25.Shown in Figure 106, almost very close to each other between the bottom of the upper surface 12d of the top of the sidewall 25i of revolving part 25 and upper shell 12, therefore, vertical movement that can regulation revolving part 25.Therefore, revolving part 25 can prevent effectively that the axle 37,38 of first, second valve 21,22 from raising and throw off from the axis hole 39 of lower house 11 when 21,22 rotations of first, second valve.
Shown in Figure 106, the dish support section 25a of revolving part 25 has the upper surface 25k of inclination, therefore, coils 100 parts with the upper surface 25k of the dish support section 25a of close sidewall 25i and contacts.In this structure, even if annular disk support section 25 width increase increasing the physical strength of revolving part 25, upper surface 25k only contacts with a part around the signal record side 100A of the dish 100 of its excircle.Therefore, signal recording area is difficult to contact with dish support section 25a.Should be noted that with the top of coiling the 100 dish support section 25a that contact be positioned at the same vertical plane in the top of the projection 21w of first, second valve 21,22 and 22w on.
Below, dish 100 be fixed or be shifted out to explanation how will by first, second valve 21,22 closed or that open.Figure 107 is presented at first, second valve 21,22 of first, second valve 21,22 closure states and revolving part 25 vertical view of position separately.Figure 108 is the sectional view that shows tray salver 320 when Figure 107 center line G-G intercepts.Figure 109 is presented at first, second valve 21,22 of first, second valve 21,22 openings and revolving part 25 vertical view of position separately.Figure 110 is the sectional view that shows tray salver 320 when Figure 109 center line H-H intercepts.In Figure 107 and Figure 109, dish 100 is represented by two-dot chain line.
Shown in Figure 107, when first, second valve 21,22 closures, dish folder 21b, 22a and 22b protrude to the center of coiling 100 by groove 25g, 25d and the 25h of revolving part 25 sidewall 25i, thereby clamp dish 100 thereon.Shown in Figure 108, dish folder 22a and 22b have downward inclined-plane 22a ' and the 22b ' that reduces gradually that contacts with the outward flange of the first side 100B of dish 100.Therefore, dish folder 22a and 22b not only will coil 100 presses to its center, and presses to first, second valve 21,22.Though not shown, another dish folder 21b also is same state.As a result, the part of the signal record side 100A of dish 100 contacts with dish support section 25a around its excircle.In addition, as illustrating in the 20 preferred implementation, the projection 21w of first, second valve 21,22 and 22w contact with the part of the signal record side 100A of the dish 100 of close its center pit 100h (not shown).In this mode, dish support section 25a and the projection 21w of first, second valve 21,22 and 22w and the air of the signal recording area on dish 100 signal record side 100A by revolving part 25 separates.Therefore, do not have dust or trickle particle deposition, can not produce scraping yet at signal recording area in the signal record zone.
The diameter of the hole 20h that is limited by first, second valve 21,22 is approximately equal to the diameter 100h of the center pit of dish 100.Therefore, though if this tray salver 320 placed face down when first, second valve 21,22 closures, any part that does not also have the signal record side 100A of dish 100 would be exposed in the hole 20h of first, second valve 21,22.Therefore, do not have dust or trickle particle deposition on the signal recording area 100A of dish 100.
In order to open first, second valve 21,22, opener/closer 25j cooperates with the valve opened/closed mechanism of disk drive, and rotation arrow 25A indicated direction.Then, revolving part 25 beginning is rotated in the dish storage compartment, and projection 25e and 25f also begin the center rotation around dish 100.Projection 25e and 25f cooperate with gathering sill 27e and 28f respectively.Therefore, projection 25e and 25f rotate in gathering sill 27e and the 28f along arrow 27E and 28F indicated direction respectively, compress the sidewall of gathering sill 27e and 28f simultaneously.When the sidewall of gathering sill 27e and 28f compressed by projection 25e and 25f, first, second valve 21,22 rotated to arrow 21A and 22A indicated direction respectively on axle 37 and 38.
Dish folder 21b also begins to rotate to arrow 21A indicated direction on axle 37, simultaneously, dish folder 22a and 22b begin to rotate to arrow 22A indicated direction on axle 38.Therefore, dish folder 21b, 22a and 22b leave dish 100 and unclamp dish 100.
When first, second valve 21,22 was opened, the projection 35 and 36 on first, second valve 21,22 also began to rotate to respectively direction 21A and 22A.Simultaneously, dish 100 does not move.Therefore, projection 35 contacts with non-signal recording area 100e on dish 100 the signal record side 100A with 36. Projection 35 and 36 is positioned on the vertical plane that is higher than projection 21w and 22w.Therefore, when projection 35 when 36 contact with signal record side 100A, projection 21w does not contact with signal record side 100A with 22w.Therefore, can prevent projection 21w and 22w scraping signal record side 100A, particularly its signal recording area.
Shown in Figure 109, when revolving part 25 rotated to certain angle, projection 25e and 25f were with the very fast end that arrives its gathering sill 27e and 28f respectively.Then, first, second valve 21,22 will fully be opened to expose magnetic head and chuck opening 11h and 11c fully.
At this moment, the groove 25c of the dish support section 25a of revolving part 25 aligns with magnetic head opening 11h, and dish support section 25a is exposed in the magnetic head opening 11h without any part.Therefore, when first, second valve 21,22 complete openings, the magnetic head of disk drive is accesses disk 100 easily, and can not produce interference with revolving part 25.
In addition, shown in Figure 109 and 110, even when first, second valve 21,22 is opened, the projection 35 of first, second valve 21,22 still contacts with non-signal recording area 100e on the signal record side 100A of dish 100 with 36.Therefore, signal recording area can be by projection 35 and 36 scrapings.
For closed first, second valve 21,22, corresponding component should move along opposite direction.That is to say that when first, second valve 21,22 closures, dish folder 21b, 22a and 22b also finally clamp dish thereon near dish 100.These operations specify in the 8th to 13 preferred implementation, will omit its explanation herein.
To the structure and the operation of protector 24 be specifically described below.Shown in Figure 111, protector 24 comprises sidewall 24d and is arranged on a pair of axle 24b of sidewall 24d end.In the bottom of sidewall 24d, be provided with a pair of contact portion 24a.The first contact portion 24a need contact with dish 100 outer surface, and has and coil the curved surface of 100 the same radius-of-curvature of outer surface.The rear side of sidewall 24d is the second contact portion 24f.Arm 24c is arranged near each 24b and has the 3rd contact portion 24e in its end.
Shown in Figure 112, protector 24 is arranged on the position of its 24b between the sidewall 25i of the upper surface 12d of upper shell 12 and revolving part 25.As arrow 24A indication, protector 24 can be swung on axle 24b.The line parallel that the center separately of axle 24b is linked together is in the tangent line that is limited by relative dish 100, and is positioned on the vertical plane of the first side 100B that is higher than dish 100.
Figure 113 and 114 is the sectional views that show when first, second valve 21,22 closures at the protector 24 at one end and center.Shown in Figure 113 and 114, sidewall 24d is pressed to the center of dish 100, so that the projection 25m of revolving part 25 contacts with the second contact portion 24f of protector 24, and the first contact portion 24a contacts with the outer surface of dish 100.Therefore, do not have dust or foul signal record side 100A by groove 25c (referring to Figure 104) the arrival dish 100 of dish support section 25a.In this mode, dish support section 25a and protector 24 and the excircle Continuous Contact of coiling 100.Thereby prevent dust or foul arriving signal record side 100A.
When revolving part 25 rotation when opening first, second valve 21,22, the projection 25m of revolving part 25 is away from protector 24.As a result, there is not acting force to be applied on the protector 24 to dish 100.
Further open and revolving part 25 when being further rotated when first, second valve 21,22, the outer surface of revolving part 25 sidewall 25i will contact with the 3rd contact portion 24e of protector 24 very soon, thus with sidewall 24e to external pressure.Figure 115 and 116 is the sectional views that at one end show protector 24 with the center.Shown in Figure 115, dish 100 outer surface comes off with the first contact portion 24a of protector 24.As a result, dish 100 rotates in the dish storage compartment.
In this mode, protector 24 swing when revolving part 25 rotation, thus alternately contact and come off with the outer surface of dish 100 with the outer surface of dish 100, make and coil 100 and rotate freely.
As mentioned above, in this preferred implementation, the label side 100B of dish 100 shows in tray salver 320.Therefore, tray salver 320 can have preferably structure and reduce thickness.
In addition, first, second valve 21,22 can be by rotation revolving part 25 to open and closure.When valve 21,22 closures, dish 100 can stably be clamped by dish folder 21b, 22a and 22b.
In addition, when dish 100 was clamped in the dish storage compartment, the label side 100B of dish 100 exposed.Even so, the projection 21w of the dish storage compartment 25a of revolving part 25, first, second valve 21,22 and 22w and protector 24 fix on to prevent to coil 100 signal record side 100A with revolving part 25 interlocking and are stained with dust, foul or are swiped.
In above-mentioned the 20 preferred implementation, opening 11r is arranged on the side surface of lower house 11, comprises the enterprising line operate of side surface on the opposite side surface of magnetic head opening 11h in adjacency for use in the opener/closer 25j of rotation revolving part 25.On the other hand, opener/closer 25j can be arranged on any other side surface of box body 10.On the other hand, also many opener/closers can be set.For example, the opener of above-mentioned preferred implementation/closer 25j can be used as first opener/closer and uses, and projection can be used as second opener/closer of the sidewall 25i that is used for revolving part 25 to be positioned at magnetic head opening 11h.Selectively, shown in Figure 105, projection 49 can be used as second opener/closer and is arranged to press from both sides 22a near the dish of second valve 22, so that can direct control second valve 22.In the case, when second valve 22 moves, revolving part 25 rotations, thus synchronously move first valve 21.
In above-mentioned the 20 preferred implementation, protector 24 prevents the signal record side 100A of the groove 25c arrival dish 100 of dust by coiling support section 25.On the other hand, also can use Any shape to prevent that dust from entering tray salver 230 by groove 25c.
For example, as the sketch among Figure 117, the groove 12g of the inner surface 12i of box body 10 can be by extension inner surface 12i closure, and the dish of second valve 22 folder 22b (not shown) can be arranged on the position of relative dish 100 centers and groove 12g symmetry.As the dish folder of above-mentioned the 13 embodiment, dish folder 22b need move to the center of dish 100, and elastic force need be applied to dish folder 22b to the center of dish 100.On the other hand, as the dish folder of above-mentioned the 19 preferred implementation, elastic component can be set to be used for and a part of coiling the 100 dish folder 22b that contact, so that its elastic force that applies makes dish 100 press to the center shown in Figure 118.
Specifically, this dish folder 22b with coil 100 and contact and clamp thereon, thereby will coil the groove 25c that 100 outer surface is pressed to the inner surface 12i of box body 10.The size of dish storage compartment and dish 100 almost is equal to each other.In addition, the radius-of-curvature of inner surface 12i is coiled the size of 100 outer surface no better than.As a result, the outer surface of dish 100 closely contacts with the inner surface 12i of box body 10.Therefore, inner surface 12I and the dish support section 25a signal record side that prevents dust arrival dish 100 together.
This structure does not need protector 24, has therefore simplified the structure of tray salver.
Embodiment 21
Hereinafter, will the tray salver 321 according to this aspect the 21 concrete preferred implementation be specified.
Figure 119 is the decomposition diagram that shows the tray salver 321 of the 21 preferred implementation.The tray salver 321 of this 21 preferred implementation is different from the tray salver 320 of the 20 preferred implementation shown in Figure 104, and wherein tray salver 320 comprises difform dish block 55 and the historical hole 11n of the removal on its lower house 11.Therefore, the explanation of the 21 preferred implementation will concentrate on dish folder 55 and remove historical hole 11n below.
Shown in Figure 119, the side surface that dish folder 55 is arranged near box body is made up of upper and lower casing 12,11, so that face the opposite side surface of the box body with magnetic head 11h.Axle 55a is arranged on the end than long side surface near dish block 55, and its other end comprises the bolt part 55d with projection 55e.
Upper shell 12 comprises that axis hole 12m, the bolt part 55d of the axle 55a that holds dish block 55 inject opening 12p wherein, and another hole 12n that holds the projection 55e of bolt part 55d.Upper shell 12 also comprises recess 12k, and when being connected to upper shell 12 with box lunch dish block 55, the upper surface of dish block 55 aligns with the upper surface 12d of upper shell 12.Axis hole 12m and opening 12p are formed at recess 12k.When dish block 55 protrudes when advancing to coil window 12w and being positioned on the dish 100 of storage, the projection 55e inserting hole 12n of bolt part 55d is fixed to upper shell 12 thereby will coil block 55.
Lower house 11 comprises removes historical hole 11n.Figure 120 shows the historical hole 11n of removal of up-sizing and parts around it.Shown in Figure 120, remove historical hole 11n and almost be coated with cover piece 56.Specifically, cover piece 56 is connected to the madial wall of removing historical hole 11n by web member 56a.Cover piece 56 has cylinder (or pin) shape and comprises projection 56b at its top.
Remove the center-aligned of the axle 55a of the center of axis hole 12m of the center of historical hole 11n and upper shell 12 and dish block 55.To illustrate afterwards that cover piece 56 cooperates with dish block 55.Therefore, rotate on its 55a when coiling block 55, revolving force is applied on the cover piece 56 with this direction, so that around its 56c rotation cover piece 56.As a result, web member 56a unclamps, and cover piece 56 falls down from lower house 11, opens fully and remove historical hole 11n.
When making tray salver 321, dish 100 is stored in the dish storage compartment that the inner surface 12i by upper shell 12 limits.After this, when user's rotating disc block 55 with when tray salver 321 removals coil 100, cover piece 56 will fall down, and open and remove historical hole 11n.In case cover piece 56 has been removed, remove historical hole 11n and stay open, even another dish 100 is also like this when being stored in the tray salver 321 by operation board block 55.In other words, as long as remove historical hole 11n cover piece 56 closures, the dish 100 that then is stored in the tray salver 321 should be the dish of original storage during tray salver 321 manufacture processes.On the other hand, open, then be stored in the dish that dish 100 in the tray salver 321 may be different from original storage during tray salver 321 manufacture processes if remove historical hole 11n.
The disk drive that this tray salver 321 is housed detects the closure or openness state that this removes historical hole 11n, thereby controls read or write according to the result.For example, suppose that the tray salver of making 321 stores the dish that reads or writes according to unique predetermined format.In this case, if the packing that disk drive identification is stored in the tray salver 321 can read maybe and can write according to predetermined format.Then disk drive will be read or write operation on dish fast based on this form.On the other hand, historical hole 11n opens if disk drive is found the removal of tray salver 321, and then to detect the dish that is stored in tray salver 321 be unknown form to disk drive.In this case, in order to discern the form that is stored in tray salver 321 mid-games, disk drive at first is applied to dish with various test signals.Then according to test result, disk drive reads or writes the signal on the dish under top condition.
Hereinafter, the also structure of listed price block 55 and the operation that is used for the exchange original disc 100 of different structure specifically.
Figure 121 shows dish block 55 and protrudes on dish 100 to prevent to coil 100 states that fall down by the dish window 12w of upper shell 12.In this state, tray salver 321 both can store also can inject disk drive.Figure 122 and 123 is the sectional views that are presented at a 55a and bolt part 55d tray salver 321 parts on every side when Figure 121 center line J-J intercepts respectively.Figure 124 is the sectional view that shows the part of tray salver 321 when Figure 121 center line K-K intercepts.
Shown in Figure 121, dish block 55 is relative with another dish block 12s that protrudes to the center of dish window 12w from upper shell 12.Dish block 55 has the arc concave side surface 55f along its length.
Shown in Figure 122, upper shell 12 comprises the round boss 12q that wherein is limited with axis hole 12m.As mentioned above, the axle 55a of dish block 55 injects axis hole 12m.Axle 55a is included in the projection 55p of its bottom, so that can not unclamp axis hole 12m easily.In addition, in axle 55a, be limited with the inner space that interior diameter is removed historical hole 11n diameter no better than.Cover piece 56 is stored in the inner space.The projection 56b of cover piece 56 cooperates with the recess 55b of dish block 55.Align with the turning axle 56c of cover piece 56 in the center of 55 55a of dish block.In addition, as mentioned above, cover piece 56 is connected to the madial wall of removing historical hole 11n by web member 56a.Web member 56a is thinner than the bottom of lower house 11.
Shown in Figure 123, contact at the opening 12p of the bolt part 55d reeve upper shell 12 that coils block 55 other ends and with the trailing flank of upper shell 12.The projection 55e that is arranged on bolt part 55d end cooperates with the hole 12n of upper shell 12.Dish block 55 also comprises the bridge portion 55f that reduces thickness, when arrow 55A indicated direction is compressed in Figure 123 with convenient projection 55e, and the distortion of bolt part 55d local elasticity.In addition, the bolt part 55d of dish block 55 and the relevant surface in contact of its upper shell 12 are respectively arranged with step portion 55g and the 12o that is fitted to each other.These step portion 55g and 12o are arranged to prevent that bolt part 55d and its peripheral part from promoting above upper shell 12 when 55 rotations of dish block.
For from tray salver 321 removal dishes 100, the projection 55e that cooperates with the hole 12n of upper shell 12 is recessed along Figure 13 and 124 indicated direction 55A, and simultaneously, dish block 55 rotates to arrow 55B indicated direction among Figure 121.Then, shown in Figure 124, the bridge portion 55f elastic deformation of bolt part 55d, and also the inclined-plane 12v that clamp on the rear surface with upper shell 12 at the top of bolt part 55d projection 55e when sliding contacts.Because inclined-plane 12v is arranged on the rear surface of upper shell 12, so, being applied on it along inclined-plane 12v even without very big power, bolt part 55d also can arrive the dotted line position shown in Figure 124 easily.For the bridge portion 55f of the bolt part 55d that makes elastic deformation returns to its original-shape, when bolt part 55d arrives this position, the top of projection 55e be positioned at vertical plane same when it cooperates with hole 12n on.
Simultaneously, shown in Figure 122, dish block 55 rotates near the direction 55B its 55a center.As a result, the power that makes cover piece 56 rotate near the direction 55B of its turning axle 56c is applied on the cover piece 56, thereby unclamps web member 56a and cover piece 56 is fallen.
Figure 125 is that display panel block 55 has moved to this position, can allow the user take the state of dish 100 away from tray salver 321.At this point, shown in Figure 124, bolt part 55d contacts with the inner surface of upper shell 12 simultaneously, and therefore, dish block 55 no longer rotates to direction 55B.
Shown in Figure 125, the part of dish block 55 is still protruded into dish window 12w.Yet, moving to dish block 12s slightly as fruit tray 100, dish block 55 will no longer be positioned at above the dish 100.Then, the user can be by being placed on finger its center pit and catching dish 100 to take dish 100 away from tray salver 321 in the edge of lifting dish 100 on every side from dish block 55 on upper shell 12.
Figure 126 and 127 is the sectional views that show when Figure 125 center line J-J intercept respectively in axle 55a and bolt part 55d tray salver 321 parts on every side.As mentioned above, when 55 rotations of dish block, cover piece 56 descends.Therefore, when dish block 55 when having moved to extreme position, remove historical hole 11n will be shown in Figure 126 complete opening.In addition, shown in Figure 127, the projection 55e of bolt part 55d cooperates with the recess 12r of upper shell 12.Therefore, the bridge portion 55f of elastic deformation returns to its original-shape.
When the dish 100 of original storage when tray salver 321 shifts out, another dish 100 is stored in the tray salver 321, coils block 55 then along the opposite direction rotation of arrow 55B.When dish block 55 arrived its original position shown in Figure 121, the projection 55e of bolt part 55d cooperated with the hole 12n of upper shell 12 once more, is fixed to once more on the upper shell 12 and coil block 55.
For the dish 100 of replacing another dish, as above the operation board block 55.Yet,, fall by the rotation of dish block 55 not having cover piece 56 owing to shifted out cover piece 56.
In the tray salver 321 of this 21 preferred implementation, dish block 55 has arc concave side surface 55f.Therefore, so many even dish block 55 does not rotate, dish block 55 also can stop protrusion on dish 100 at once.In addition, because dish block 55 rotates to so little degree, the bolt part 55d of dish block 55 also can keep in touch with upper shell 12 and cooperate.Therefore, even shift out from tray salver 321 when dish 100, the two ends of dish block 55 also can keep contact with upper shell 12, and coil block 55 and also can keep enough physical strengths.Therefore, promptly the user since mistake is fallen tray salver 321 or in removal dish 100 platen block 55 exert oneself very much, dish block 55 also can be damaged.
In addition, according to above-mentioned preferred implementation, when 55 rotations of dish block, remove historical hole 11n and open.Therefore, different with traditional tray salver, needn't the fracture short-movie in historical hole of user.
In addition, in above-mentioned preferred implementation, cover piece 56 is cylindrical.Mode as an alternative, cover piece 56 also can be any other shape, as long as cover piece 56 can be connected to lower house 11 in this way, local at least the covering removed historical hole and removal when 55 rotations of dish block, for example, cover piece can comprise: the short-movie that is provided for removing historical hole 11n; And be arranged between dish block 55 and the joint and the auxiliary member that when 55 rotations of dish block, fractures.
In addition, in above-mentioned preferred implementation, dish block 55 is closely clamped and the primary importance that can not fall from tray salver 321 from coiling 100, move to dish 100 by parallel discs 100 rotating disc blocks 55 and prepare the second place that shifts out from tray salver 321, or vice versa.Mode as an alternative can be at different direction displacement disc blocks 55.
Figure 128 and 129 shows another dish block 57 of the side surface slip that is parallel to tray salver 321.Dish block 57 also has the arc concave side surface 57f along its length.Specifically, Figure 128 shows the state of clamping dish 100 by dish block 57.Shown in Figure 128, in this state, dish block 57 is protrusion dish 100 partly.In order to shift out dish 100, dish block 57 is along moving as arrow 57A among Figure 129 (that is, vertically coiling the long side surface of block 57) indicated direction.The side surface 57a of dish block 57 preferably is provided with protrusion or the recess that cooperates with upper shell 12, so that dish block 57 can not unclamp upper shell 12 so easily.
The side surface 57a of dish block 57 also is an arc and recessed.Therefore, just pass through displacement disc block 57 slightly, dish block 57 can stop protrusion on dish 100 at once.For this reason, dish 100 can shift out from tray salver 321, and great majority dish block 57 keeps contacting with upper shell 12 simultaneously.As a result, even when dish 100 conversion, dish block 57 can not lost its physical strength yet.
Figure 130 and 131 is axle another dish blocks 58 on the 58a that are presented at the two ends of its long side surface that is fixed to upper shell 12.In this another preferred implementation, for example, shown in Figure 131, elastic force preferably is applied to dish block 58 from spring, so that dish block 58 keeps contacting with upper shell 12.If desired, dish block 58 can rotate to the position shown in Figure 131.Yet because dish block 58 also has arc concave side surface 58f along its length, dish 100 can shift out from the position shown in Figure 130 by rotating disc block 58 slightly.
Be provided for tray salver 321 as fruit tray block 57 or 58, tray salver 321 can have the mechanism of removing cover piece when dish block 57 or 58 slides or rotates.On the other hand, covering the cover piece of removing historical hole can not interlock with dish block 57 or 58.In this case, have only after the user shifts out cover piece, tray salver can have makes dish block 57 or 58 mechanisms of sliding or rotating.
Embodiment 22
Hereinafter, will the tray salver 321 according to this aspect the 22 concrete preferred implementation be specifically described.
Figure 132 is the vertical view that shows the tray salver 321 of the 22 preferred implementation.Figure 133 is the sectional view of the tray salver 322 that L-L along the line analyses and observe among demonstration Figure 132.As the same with the tray salver of the 20 preferred implementation of 118 explanations with reference to Figure 117, tray salver 322 can prevent that also dust from advancing tray salver 322 and not using any protector by the groove 25c of dish support section 25a.Though in Figure 132, do not specifically illustrate.But tray salver 322 also comprises first, second valve 21,22, be used for the 20 and the revolving part 25 and the dish block 55 of the 21 preferred implementation be illustrated.Each of these parts can have and the above-mentioned the 20 and the same structure of corresponding component of the 21 preferred implementation.
In the tray salver 320 and 321 of the 20 and the 21 preferred implementation shown in Figure 104 and 119, the sidewall 12i of upper shell 12 comprises respectively and is positioned at the groove 12g that is in same position when first, second valve 21,22 is closed with the groove 25c of dish support section 25a.
Simultaneously, in the tray salver 322 of this 22 preferred implementation, sidewall 12i does not have groove 12g, but continuously around around the dish 100.In addition, shown in Figure 134, the sidewall 12i ' of extension is arranged on below the sidewall 12i, so that contact with the outer surface of dish 100.The sidewall 12i ' that extends is positioned at the position corresponding to groove 12g.
Therefore sidewall 12i qualification dish window 12w has than coiling 100 big radius-of-curvature.On the other hand, the sidewall 12i ' of extension has the radius-of-curvature same with the dish 100 shown in Figure 135.Shown in Figure 132, align with the center C 1 of dish storage compartment by the cylindrical center that sidewall 12i limits.Simultaneously, the center of the radius-of-curvature by sidewall 12i ' qualifications of extending with put C2 and align.That is to say some C2 deviation point C1.The sidewall 25i that should be noted that revolving part 25 limits the right cylinder that aligns with the center C 1 of dish storage compartment in the center, and around a C1 rotation.
In addition, dish folder 22b clamps dish 100 thereon, so that coil 100 center-aligned C2.Though have only a dish folder 22b in Figure 132, two other dish folder 21b and 22a (not shown) are also clamped dish 100 thereon, so that coil 100 center-aligned C2.In this position, dish support section 25a supporting disk 100 contacts with the signal record side (that is back) of coiling 100 thereon and not.Therefore, the misalignment point C1 of dish support section 25a.The cylindrical radius that distance between some C1 and the C2 limits according to the radius of sidewall 12i and dish 100 and can changing.For example, be 5 inches as the radius of fruit tray 100, then put between C1 and the C2 distance preferably from about 0.5mm to about 1.5mm.Reason is as follows.Specifically, if distance is less than about 0.5mm, because when rotating in dish 100 tray salvers of putting in the disk drive 322, dish 100 will tremble, so the dish 100 of rotation may contact with sidewall 12i.Yet, as the distance between fruit dot C1 and the C2 greater than about 1.5mm, coil 100 and the dish storage compartment sidewall 12i between the gap will be so wide so that many dusts or other foul can enter tray salver 322 by the gap.
Figure 137 shows that L-L along the line intercepts the sectional view that hour indicator presss from both sides 22b and tray salver 322 peripheral part among Figure 132.The upper surface 25k of dish support section 25a is what tilt, contact and coil 100 parts with the upper surface 25k of the dish support section 25a of the sidewall 25i (not shown among Figure 137) of close revolving part 25, in this preferred implementation, this partial parallel of the upper surface 25k of the dish support section 25a around sidewall 25i is in the bottom of lower house 11.Therefore, when first, second valve 21,22 close so that coil 100 when clamping by dish folder 21b, 22a (not shown) and 22b, dish 100 with coil support section 25a and in this regional 25b, contact.Dish support section 25a is limited by the circle of the strokes and dots as shown in Figure 132 25n with the inner periphery of the dish 100 regional 25b that contact.
Shown in Figure 132, the regional 25b of dish support section 25a almost is positioned at around the excircle of dish 100, but separated by groove 25c.In addition, the inner periphery 25n of regional 25b defines the circle that aligns with some C2 in the center.On the other hand, the excircle of regional 25b is limited by coiling 100 excircle.Therefore, regional 25b limits and passes through the recessed annular region of groove 25c interruption for two concentric circless that align with some C2 by its center.
When first, second valve 21,22 (not shown in Figure 132) closure so that coil 100 dishes folder 21b, 22a and 22b when clamping by first, second valve 21,22, the center of dish 100 with put C2 and align.In addition, the radius-of-curvature of sidewall 12i ' because dish 100 radius-of-curvature equals to extend, the outer surface of dish 100 closely contacts with extension sidewall 12i ' in the position of another tray salver that groove 12g exists.In other words, the center of the misalignment dish storage compartment of the dish of clamping by dish folder 21b, 22a and 22b 100 contacts and clamps with extension sidewall 12i ' so that coil 100 outer surface.
In addition, when first, second valve 21,22 (not shown in Figure 132) is closed, dish support section 25a and the dish 100 recessed annular region 25b that contact with each other also with the misalignment of dish storage compartment.Therefore, dish 100 signal record side (that is, the back side) peripherally contact with dish support section 25a around it, and coils 100 outer surface and pass through groove 25c interval and contact with extension sidewall 12i ' coiling support section 25a.
On the other hand, near center pit 100h, the dish 100 that illustrates in above-mentioned the 20 preferred implementation contacts with 22w with the projection 21w of first, second valve 21,22.Therefore, dish 100 signal recording area separates with air fully, so do not have dust deposit at the signal recording area that coils 100 at all.
In addition, shown in Figure 136 and 137, the dish of second valve 22 of tray salver 322 folder 22b has conical bottom 26c, and recess 11x is provided for lower house 11 to hold the bottom 26c of dish folder 22b simultaneously.Therefore, inequal as the thickness of fruit tray 100 diameters, but less times greater than standard thickness, then elastic deformation takes place in the end of the recess 11x of close lower house 11 shown in Figure 137 in the part 26b of second valve 22.As a result, the sloping portion 22b ' of dish folder 22b contact with the outward flange of dish 100, and first, second valve 21,22 firmly clamps dish 100 thereon, and can not make coil 100 optionally mobile.In addition, when second valve, 22 elastic deformations, dish folder 22b is applied to dish with elastic force to its center.Then, shown in Figure 132 and 134, compression plate 100 is also near contact extension sidewall 12i ' once more.Then, can prevent the signal recording area of unwanted dust deposit more completely at dish 10.
Just clamp as required in order to make dish 100, no matter how to change and coil 100 diameter or thickness, tray salver 322 can be designed to the diameter of the dish 100 that will clamp with box lunch or thickness when equaling the central value of its critical field, second valve 22 elastic deformation slightly shown in Figure 137, and when the diameter of the dish 100 that will clamp or thickness when equaling the smallest limit of its critical field, elastic deformation takes place in second valve 22 hardly shown in Figure 136.
As mentioned above, according to this preferred implementation,, there be not the signal recording area of dust deposit at dish 100 even without protector 24 is set at all yet.That is to say, neither need protector 24 also not need to be used to interlock protector 24 and revolving part 25, therefore greatly simplified the structure of tray salver.
Embodiment 23
Hereinafter, will the tray salver 323 according to this aspect the 23 concrete preferred implementation be specifically described.
Different with traditional tray salver, according to any tray salver storage disks of the various preferred implementations of the invention described above therein and a side of dish expose.Therefore, tray salver of the present invention can be more thinner than traditional tray salver.In addition, owing to shown the label side of dish, so whole tray salver can have structure preferably.
Yet, because a side of dish will expose in this tray salver, so the label side that the user can contact disc.Therefore, the Cu Xin user label side of compression plate at full tilt.Therefore, the tray salver of this form should be clamped dish in the following manner, so that prevent the signal record side scraping of coiling or prevent that dish itself is out of shape in this case.In view of these possible rough sledding, for example, the present invention studies emphatically how to clamp to coil and prevents that its signal record side from being swiped.
Figure 138 shows (for example to be used to clamp dish 100 clamping structure 59 thereon, dish support section 25a) and be arranged on space below the signal recording area 100d of dish 100, like this, compressed by the user even coil 100, signal recording area 100d also can clamped structure 59 scrapings powerfully.The size that should be noted that the some parts of clamping structure 59 is not the ratio among Figure 138, so that the feature of the clamping structure 59 that is limited to this space is clearly understood.Therefore, be presented at the ratio of this respect among Figure 138 with in kind different.
If 100 times a large amount of spaces can be arranged at dish, the height in space can only be less times greater than the maximum camber of dish 100.This is because in the case, no matter coiling 100 has much distortion, coils 100 and can not contact in clamping structure 59.Yet the tray salver with sufficient room like this will be too thick.So actual will minimizing in space below dish 100.In order to reduce the space, need clamp dish 100, so that have as far as possible little bending.And in order to reduce bending, the part of the dish 100 that clamps by clamping structure 59 preferably is positioned as close to the signal record side 100A of dish 100.Shown in Figure 138, limit by internal diameter Rin and external diameter Rout in the part of the clamping structure 59 of dish 100 signal record side 100A upper support.That is to say that the dish 100 not only inside of the clamping structure 59 by being positioned at internal diameter Rin is clamped, and clamp by the outside that is positioned at the outer clamping structure 59 of external diameter Rout." internal diameter Rin " is for from coiling 100 center to nearer than the center of dish 100 and be limited near the distance the point of signal record side 100A inner periphery herein." external diameter Rout " is for from coiling 100 center to nearer than the outward flange of dish 100 and be limited near the distance the point of signal record side 100A excircle on the other hand, herein.As mentioned above, these 2 of interior external diameter Rin of qualification and Rout are positioned as close to signal recording area 100d.For example, has about 5 inches diameter (that is, radius is approximately 60mm) as fruit tray 100.Inside radius Rin 20mm preferably approximately then, and external diameter Rout 59mm preferably approximately.
Be arranged on below the dish 100 in case the space 69b of stop signal recording areas 100d scraping limits in the following manner.At first, the height of restriceted envelope 69b (or degree of depth) S (mm).Secondly, limit three round 69d, 69e and 69f.Specifically, justifying 69d has radius and equals external diameter Rout and be limited on the 100A of signal record side.Circle 69e have the radius that obtains by (Rout-1.2S) and be limited to be parallel to and with plane that signal record side 100A separates on; And circle 69f has the radius that obtains by (Rout-16.2S) and is limited to and is parallel to and separates on the plane of S mm with signal record side 100A.Top and bottom has side surface 59a by the truncated cone that circle 69d and 69e limit respectively, and top and bottom has side surface 59b by another truncated cone that circle 69e and 69f limit respectively.
Right cylinder also is defined as to have the side surface 59d of height (degree of depth) S that measures from the circular base of coiling the radius R in that 100 center measures and from signal record side 100A.The space 69b that is arranged on below the signal recording area 100d obtains by removing right cylinder, and is limited by the side surface 59d from the two-stage truncated cone that limited by side surface 59a and 59b.
The height of S value restriceted envelope 69b.Therefore, the S value is big more, even coil 100 distortion, the possibility of signal recording area 100d scraping is more little.Yet when the S value increased, tray salver thickness increased.Therefore, in order to make thin tray salver, preferred S value is as far as possible little.Even the present invention discloses by test and the S value that confirms about 1mm also enough is swiped to prevent to coil 100 signal record side 100d greatly, as long as coil 100 bending by causing by user's craft applied pressure.
On the other hand, the clamping region 100e ' of dish 100 is preferred does not contact with clamping structure 59 in the zone that is limited by internal diameter Rin.Reason is as follows.When tray salver 323 put into disk drives from/read and/or during write signal, clamping region 100e ' will contact with rotating disk or binding clasp at dish 100.Therefore, if this regional 100e ' has swiped or has been coated with dust partly, then can not such as hope clamping disk(-sc) 100.Clamping region 100e ' respectively by two diameters be approximately 22mm and approximately the concentric circles of 33mm limited and the center-aligned of its center and dish 100.Clamping region 100e ' accounts for the very little number percent of the whole area of dish 100.Therefore, even user's compression plate 100 above clamping region 100e also is difficult to crooked dish 100.For this reason, have only as space 69a to be provided with so that when contacting with whole clamping region 100e ', space 69a can have any height (degree of depth).
If Figure 139 shows that space 69b is arranged on below the dish 100 that S value is set at 1mm and pressure is applied on the dish 100 to space 69b, coiling 100 distortion has great sketch.The present inventor discloses by test and confirms and can not surpass 3kg by the manual pressure that is applied on the dish 100 of user.Even the present inventor also discloses the pressure as the maximum 3kg that apply, dish 100 also will be fully in the 69b of space bending can't contact with side surface 59a or 59b.
In this case, the space 69b of qualification has minimum needs size to be swiped to prevent to coil 100 signal recording area 100d.Therefore, bigger space can be set below the signal recording area 100d of dish 100.That is to say that space 69b can be arranged on outside side surface 59a shown in Figure 140 and 141 and the 59b.Yet, in this case, for the physical strength of the exterior portion that strengthens clamping structure 59 fully, the excircle of clamping disk(-sc) 100, reinforcing section 59 ' or 59 " be preferably disposed on and close on exterior portion.Can use effectively side surface 59a and 59b with determine these reinforcing sections 59 ' or 59 " admissible set.
Hereinafter, the tray salver of considering design in view of these will be specified.Figure 142 is the vertical view of display panel 123.Figure 143 is the sectional view that shows when Figure 142 center line P-P intercepts.Figure 144 is the decomposition diagram that shows tray salver 323.In the tray salver 323 of this 23 preferred implementation, represent with same label according to each parts above-mentioned the 20, the 21 or the 22 same corresponding component of preferred implementation tray salver.
As the tray salver 322 of above-mentioned the 22 preferred implementation, tray salver 323 does not have protector, but coils 100 by dish 100 outer surface being contacted with the sidewall of upper shell 12 clamp.
More particularly, shown in Figure 142 and 144, when first, second valve 21,22 closures, tray salver 323 makes dish 100 clamp by the dishes folder 21b of first valve 21 and the dish folder 22a and the 22b of second valve 22.In this case, the sidewall 12I of dish 100 outer surface and groove 25c at revolving part 25 upper shell 12 of locating contacts.In addition, align with some C2 in the center of dish 100.Wherein the dish support section 25a of revolving part 25 aligns with some C2 with the center of the inner periphery in dish 100 zones that contact, so that described zone contacts with the signal record side 100A of dish 100 equally.On the other hand, align with some C1 in the center of revolving part 25 sidewall 25i.
Shown in Figure 142 and 144, the projection 21w of composition and 22w are arranged on around the hole 20h that first, second valve 21,22 by tray salver 323 limits.Hole 20h is corresponding with the center pit 100h of dish 100.Another is arranged to 36d projection 35d so that separate with ring 20w by predetermined distance.The upper surface of projection 35d and 36d and projection 21w and 22w are on same plane.When first, second valve 21,22 closures, projection 35d and 36d limit close its signal recording area of the continuous loop 20d that clamps part dish 100.The projection restriceted envelope 69a that between these two ring 20w and 20d, produces.When dish 100 was clamped thereon, the clamping region of dish 100 just in time was positioned at above the 69a of space.
In addition, shown in Figure 144, when the dish support section 25a of projection 36d, second valve 22 and revolving part 25 was designed to clamp on this tray salver 323 with box lunch dish 100, the space 69b shown in Figure 138 was arranged on below the dish 100.Though do not show that in Figure 143 other projection 35d and first valve 21 also are designed for same purpose.In addition, tray salver 323 also is designed to so that 1mm or more gap are arranged between fixing dish 100 and first, second valve 21,22.In addition, dish support section 25a is positioned at the outside (that is, below the side surface 59a and 59b of restriceted envelope 69b) of the space 69b shown in Figure 138, and can not hinder space 69b.
By space 69b shown in Figure 138 being set in this way below dish 100, can as estimating, protection be stored in the signal recording area of the dish 100 in the tray salver 323, even coil 100 compress at full tilt by the user also like this.
Should be noted that tray salver 323 adopts what is called " multilayer ring " or " stacked ring " that has at clamping region 100e '.Shown in Figure 138, the multilayer ring is the convex hole 100p that is arranged on dish 100 the signal record side 100A.Convex hole 100p has the circle with the coaxial formation of center pit 100h.Convex hole 100p prevents that signal recording area 100d and signal record side 100A at dish are placed on flat in the flat state situation down and contact.Convex hole 100p between clamping region 100e ' and center pit, and with the marginating compartment 1mm of center pit 100p or more multiple spurs from.Convex hole 100p has the width of about 1mm and is approximately 0.05 to 0.5mm height from signal recording area 100d surface at radial direction.More particularly, in a kind of form of dish 100, the diameter of center pit 100p is 15mm, clamping region 100e ' is limited between the circle of the circle of 22mm diameter and 33mm diameter, convex hole 100p is arranged in the zone by the circle qualification of the circle of 17.5mm diameter and 22mm diameter, the width of convex hole 100p is approximately 1mm, and the height of convex hole 100p is approximately 0.3mm or still less.Mode as an alternative, convex hole 100p also can be between clamping region 100e ' and signal recording area 100d, and with the marginating compartment 2mm of clamping region 100e ' or still less.
In the case, the dish folder 22a of the dish of the first valve 21 folder 21b and second dish and 22b be clamping disk(-sc) 100 in the following manner, does not contact with convex hole 100p so that neither contact also with clamping region 100e '.Therefore, it is enough big that the space 69a that limits by ring 20w and 20d will do, so that comprise convex hole 100p.More particularly, when first, second valve 21, during 22 closures, the dish folder 21b of first valve 21 and the dish folder 22a of second valve 22 and 22b be clamping disk(-sc) 100 in the following manner, do not contact so that neither contact with between clamping region 100e ' and center pit 100h and yet, or can neither not contact with clamping region 100e ' in this way yet and with between clamping region 100e ' and signal recording area 100d and do not contact with the marginating compartment 2mm of signal recording area 100d or zone still less with marginating compartment 0.1mm or the more zone of center pit 100h with clamping region 100e '.In the situation of the dish 100 of above-mentioned concrete form, space 69a should comprise by first circle of 17.5mm diameter and less than the zone of the first circle 0.1mm to the second circle qualification of 0.3mm.Should be noted that space 69a can be used for for continuous one clamping region 100e ' and convex hole 100p the zone or also can be by being used for the Disengagement zone that clamping region 100e ' and convex hole 100p form.
The tray salver 323 of this preferred implementation also comprises other structure that is designed to increase its parts physical strength especially, selectively connects the dust tightness that increases this tray salver 323 in the lump respectively of the dish folder of two kinds of forms, thereby increases the workability of tray salver 323.To specify these structures hereinafter.
At first, explanation is used to increase the structure of the physical strength of 323 of tray salvers.Shown in Figure 142 and 144, when first, second valve 21,22 closures, dish folder 21b, 22a and 22b are applied to dish 100 with elastic force to its center.This is because coupling part between first valve 21 and the dish folder 21b and the coupling part between second valve 22 and dish folder 22a and the 22b produce elastic deformation by dish 100.
Yet, if the user because mistake drops tray salver 323 or expose the side attempting tray salver 323 in to force rotating disc 100 by power being applied to dish 100, power outwards can be applied to dish from 100 the center of coiling and press from both sides 21b, 22a and 22b.And if this power is enough big, then may fracture first valve 21 and dish press from both sides the coupling part and second valve 22 between the 21b and coil the coupling part that presss from both sides between 22a and the 22b.In other situation, dish folder 21b is connected to the part of first valve 21 and will coil and press from both sides 22a and 22b to be connected to the part of second valve 22 too narrow, thereby can not stop respectively the acting force that is applied along arrow 21B among Figure 142 and 22B indicated direction fully.
In view of these coupling parts may fracture, the sidewall 25I of the revolving part 25 of this tray salver 323 is arranged to so that the xsect 65a of its groove 25g and 25h and 65b are not parallel to the radial direction (that is, direction 21B and 22B) of dish 100, but in the face of dish storage compartment 10d.Therefore, when first, second valve 21,22 closures, be able to regulation by xsect 65a and 65b respectively at the dish folder 21b of direction 21B and 22B and the displacement of 22b, so that it can not surpass its predetermined angle.
By setting these xsects 65a and 65b, though because mistake drops tray salver 323 or attempt deliberately outwards displacement disc folder 21b and 22b, dish folder 22a and 22b will can not fracture.In addition, when first, second valve 21,22 will be closed, even some are accidental first, second valve 21,22 of opening along the power that this direction applies, the dish folder 21b that moves along the valve 21,22 that will open will contact with 65b with xsect 65a respectively very soon with 22b.As a result, first, second valve 21,22 will can not opened accidentally.Therefore, can reduce first, second valve 21,22 of wanting closed to greatest extent and produce beyond thought moving.
In addition, if the user attempts to open wittingly first, second valve 21,22, then first, second valve 21,22 will be respectively around axis hole shown in Figure 142 37 and 38 rotations.Then shown in Figure 142, the 27e of gathering sill separately of first, second valve 21,22 and the sidewall of 28f will make the projection 25e of revolving part 25 and 25f rotate to respectively direction 25E and 25F around axis hole 37 and 38.
In this case, if if the end of gathering sill 27e and 28f moves projection 25e and 25f respectively at prolongation or gathering sill 27e and 28f on direction 25E and the 25F in direction 25E and 25F, then first, second valve 21,22 will arbitrarily move.
First, second valve 21,22 arbitrarily moves in order to eliminate like this, when first, second valve 21,22 was closed, the gathering sill 27e of projection 25e and 25f location and these ends of 28f prolonged on substantially with the arrow 27E of right angle cuts arrow 25E and 25F and 28F indicated direction.Shown in Figure 142, direction 27E and 28F are basically parallel to the line that projection 25e and 25f is connected respectively to axis hole 37 and 38.
In addition, shown in Figure 144, lower house 11 is provided with bossing 33b, and revolving part 25 is provided with bossing 25w.The height of bossing 33b and 25w is approximately equal to the height of first, second valve 21,22.Bossing 33b contacts with the rear surface of the dish support section 25a of revolving part 25.Bossing 25w be formed at box body 10 in recess 33c on the lower surface 11u cooperate.These bossings 33b contacts with the part that 25w is arranged to support with first, second valve 21,22 not contacted revolving parts 25.Therefore, even those of revolving part 25 also can not be out of shape with first, second valve 21,22 not contacted parts or lose and contact with dish 100.
As situation about having illustrated in the 14 preferred implementation, dish folder 22a comprises first, second valve 21,22, and the upper surface of the 122a of first is higher than the upper surface of second portion 222a.In addition, the top of the 122a of first is injected among the recess 12x that is arranged on upper shell 12 rear surfaces.The zone setting that recess 12x passes along the top of the 122a of first when valve will closure or openness.
Shown in Figure 142 and 144, magnetic head opening 11h be arranged on when valve will the closure or openness hour indicator position passed through of folder, and arrive the side surface of lower house 11.Therefore, when box body for by upper and lower housing 11,12 being combined when forming, near the physical strength of the box body magnetic head opening 11h will only be ensured by upper shell 12.
In tray salver 323, when valve will be closed, illustrated as the 14 preferred implementation, dish press from both sides the 122a of first of 22a can console panel 100 thereon.In addition, because the upper surface of dish folder 22a second portion 222a is positioned at vertical plane down, then upper shell 12 needn't have the thickness of minimizing on second portion 222a.Therefore, when valve will the closure or openness hour indicator recess 12x of upper shell 12 of first 122a position of folder 22a should have the thickness of minimizing, but can be the sub-fraction of entire upper surface.Therefore, the physical strength that can prevent whole tray salver excessively reduces near magnetic head opening 11h.
In addition, the tray salver 323 of this preferred implementation has the structure that increases its rigidity when the valve closure of the 13 preferred implementation explanation.
Specifically, shown in Figure 145 and 146, first, second valve 21,22 has two pairs and is interrupted contact portion 21f ', 22f ' and 21g ', the 22g ' of separation, the every pair of overlap joint that all is perpendicular to one another each other by hole 20h.That is to say that first valve 21 comprises contact portion 21f ', 22f ', and second valve comprises contact portion 21g ', 22g '.Figure 146 A and 146B are the sectional views that shows first, second valve 21,22 when respectively along Figure 145 center line N-N and O-O intercepting.In a pair of contact portion 21g ', the 22g ' shown in Figure 146 A, when valve 21,22 closures, the contact portion 21g ' of first valve 21 is positioned on the contact portion 22g ' of second valve 22 at the thickness direction of valve 21,22.At shown in Figure 146 B another during to contact portion 21f ', 22f ' closure, the contact portion 22f ' that the contact portion 21f ' of first valve 21 is positioned at second valve 22 at the thickness direction of valve 21,22 down.
In addition, shown in Figure 146 A, the edge of the contact portion 22g ' of second valve 22 comprises along the projection 38c of contact portion 22g ' extension.On the other hand, first valve 21 comprises the recess 37c that cooperates with projection 38c when valve 21,22 closures
In addition, shown in Figure 147, the projection 27a position contacting place of the dish of the second valve 22 folder 22a and first valve 21, projection 27a comprises and projection 37a, and dish folder 22a comprises the recess 38a that cooperates with projection 37a.Another recess 37b is arranged on above the projection 37a.Another projection 38b that cooperates with recess 37b is arranged on above the recess 38a.Projection 37a and recess 37b limit another contact portion 37e of first valve 21.On the other hand, recess 38a and projection 38b limit the contact portion 38e of second valve 22.These contact portions 37e and the 38e of first, second valve 21,22 is referred to herein as " the 3rd pair of contact portion ".
As mentioned above, in the tray salver 323 of the 23 preferred implementation, the contact portion 21f ' of two pairs of separation, 22f ' and 21g ', 22g ' are arranged for first, second valve 21,22, and every pair of contact portion of first, second valve 21,22 overlaps each other at the thickness direction of valve.In addition, the reversed in order that overlaps each other of the order that overlaps each other of first couple of contact portion 21f ', 22f ' and second couple of contact portion 21g ', 22g '.Utilize this structure, first, second closed valve 21,22 can not raise by accident, and its contact portion can have the rigidity of enhancing.
In addition, be respectively applied for recess 37c and the projection 38c of first, second valve 21,22 contact portion 21g ', 22g ' by setting, contact portion 21g ', the 22g ' of first, second closed valve 21,22 can be owing to for example its random motion is separated from one another at an easy rate.In this mode, first, second valve 21,22 can more closely contact with each other, and therefore increases the dust tightness of these contact portions tray salver on every side of valve.
In addition, be respectively applied for the 3rd couple of contact portion 37e of first, second valve 21,22 contact portion 37e, 38e by setting, the contact portion of first, second closed valve 21,22 can have the rigidity of enhancing.In addition, the contact portion 21g ' of first valve 21 and projection 37a are clipped in the projection 38b and the contact portion 22g ' centre of second valve 22.As a result, the contact portion of Bi He first, second valve 21,22 can have the rigidity that more strengthens.
Next, explanation is designed to selectively especially one of dish folder and is connected to structure on the tray salver 323 two types.Shown in Figure 144, the upper shell 12 of tray salver 323 comprises axis hole 12m and another axis hole 12m '.Both can be that dish folder 55 also can be 59 as preventing that coiling 100 devices that fall by dish window 12w fits among hole 12m and the 12m '.The dish block 55 of the tray salver 323 of this 23 preferred implementation preferably has the structure same with the dish block 55 of the tray salver 321 of above-mentioned the 21 preferred implementation.That is to say that by axle 55a being injected and cooperating with the axis hole 12m of upper shell 12, dish block 55 can rotate on axle 55a.Then, as situation about having illustrated in the 21 preferred implementation, the part of dish block 55 can be protruded into dish window 12w, unexpectedly drops thereby prevent to coil 100.On the other hand, rotate to the position shown in Figure 125 as fruit tray block 55, then coiling 100 can shift out from tray salver 323.
On the other hand, dish block 59 comprises projection 59a and 59b.When dish block 59 when being connected to upper shell 12, the projection 59a of dish block 59 and 59b injects respectively and cooperate with hole 12m and 12m '.Because dish block 59 is fixed on the upper shell 12 at these 2, then coils block 59 and do not rotate, but always protrudingly partly advance to coil window 12w.That is to say that when dish block 59 was connected to upper shell 12, the dish 100 that is stored in the tray salver 323 was not removable.
In this mode, can cooperate with dish block 55 by both being provided with, also axis hole 12m that can cooperate and the hole 12m ' conduct adapting device that is used for upper shell with dish block 59, these two coil one of block 55 and 59 and can selectively be connected to box body as required.That is to say, by selectively adopting two dish blocks 55 and one of 59, the dish 100 that final tray salver 323 can maybe cannot allow the user shift out to be stored in the tray salver 323.
Do not comprise the historical hole 11n of removal or the cover piece 56 of the tray salver 323 in the 21 preferred implementation at the tray salver shown in Figure 144 323.Yet, remove historical hole 11n and cover piece 56 and can be provided for tray salver 323.If remove historical hole 11n, cover piece 56 and dish block 55 is provided for tray salver 323, then will to drop to the 21 preferred implementation that has illustrated the same for cover piece 56, and 55 rotations of dish block are to shift out dish 100 from tray salver 323.Then, removing historical hole 11n will expose fully.On the other hand, be connected to upper shell 12 rather than dish block 55 as fruit tray block 59, then coiling 100 can not shift out by rotating disc block 59.Therefore, in this case, removing historical hole 11n will be covered by cover piece 56 all the time.
Secondly, specify the structure of the enhancing dust tightness of tray salver 323 with reference to Figure 144,145,148 and 149.Shown in Figure 144, the chuck of lower house 11 and magnetic head opening 11c and 11h by the flange 33a of dotted line indication among Figure 145 around.Figure 148 is the sectional view that shows the tray salver 323 of M-M intercepting along the line among Figure 145.Shown in Figure 148, the rear surface of first, second valve 21,22 comprises recess 37d and the 38d that cooperates with flange 33a respectively.
First, second valve 21,22 rotates on lower house 11.Therefore, if gapped between first, second valve 21,22 and lower house 11, when first, second valve 21,22 rotations, the dust that has been deposited on first, second valve 21,22 rear surfaces will enter box body easily.Yet, by filling the gap with this structure.Then have dust hardly and enter tray salver 323 from chuck and magnetic head opening 11c and 11h.
In addition, shown in Figure 149, the contact portion of first, second valve 21,22 around the hole 20h that limits when being looped around first, second valve 21,22 closures is provided with the recessed of cooperation and projection 35a, 36a and 35b, 36b each other.Projection 36a, the 36b of second valve 22 protrudes from the contact plane that limits when closed by valve 21,22.Therefore, do not have dust and enter tray salver 323 from hole 20h by the contact plane between first, second valve 21,22.
In above-mentioned the 23 preferred implementation, be used for clamping dish 100 dish support section 25a thereon be provided for revolving part 25 with the space 69b that limits Figure 138 and show below dish 100.On the other hand, the structure that also can adopt arbitrarily other is to limit the space 69b that shows among Figure 138 below dish 100.For example, shown in Figure 150, be used to clamp the dish 100 outer peripheral dish support section 25a ' can be provided for other upper shell 12 '.Even so, coiling below 100 to limit the space 69b that shows among Figure 138 by dish support section 25a ' and first, second valve 21,22 that forms following shape, even dish is pushed by user's brute force, the signal recording area of dish 100 will can not contact with the dish support section of valve or tray salver yet.
Embodiment 24
Hereinafter, with reference to Figure 151 the disk drive according to this aspect the 24 concrete preferred implementation is specifically described.
