Description

Tray salver
Technical field
The present invention relates to be used for storing rotationally the tray salver of disk-shaped storage medium such as CD or disk.
Background technology
Proposed the various tray salvers as the protection box of disk-like data storage medium, disk-shaped storage medium (following be referred to as simply " dish ") has single or two data storage surfaces.
For example, Japanese public publication No.9-153264 discloses a kind of tray salver, and dish wherein is completely enclosed within the disk storage part.Disk storage partly is limited to box body inside, and box body is made of upper and lower two halves.Box body comprises holes for clamping and head (head) slot.Holes for clamping can make the turntable of spindle drive motor and the dish that clamper can clamp insertion, and a slot (head access window) allows head from coiling or reading and/or write data at dish.A holes for clamping of the bottom in the holes for clamping is communicated with a slot.Therefore, when operating personnel carried this tray salver, dust just entered the inside of tray salver at an easy rate by these openings, and dish is also made dirty by finger mark easily.For this reason, tray salver will comprise that also a baffle plate seals these openings.
Yet the tray salver with this structure has following shortcoming.At first, this tray salver can not be very thin.This is because the disc storage space that limits between upper and lower two halves should be sufficiently thick, just can make the disk drive dish from be stored in this tray salver or read or write signal (or information) to described dish exactly.Disc storage space should quite thick reason also comprise: the vibration of the expection of the dish in the rotation or warpage and contingent error in the middle of the precalculated position that tray salver is placed on disk drive inside.
Secondly, formation can be sealed the cost of the baffle plate of these holes for clamping and a slot simultaneously can not be very low, like this, just increased total manufacturing cost of this tray salver.The reasons are as follows.Specifically, tray salver following half be provided with the turntable that is used for spindle drive motor and the hole of a slot, and going up half and being provided with another hole of tray salver is used for clamper.Like this, in order once to close this 3 holes, baffle plate need form a U-shaped with rectangular base, and manufacturing can be very not cheap.
The 3rd, the dish that is stored in this tray salver is unfixed in many cases, so just may cause dust or molecule deposition problems and scratch problem.Specifically,, can fixedly have CD such as the CD or the DVD of metal hubs usually though for example can utilize attraction to have the dish of metal hubs and make its fix in position and can be not mobile accidentally in tray salver, such CD can activity in this tray salver freely.Therefore, if vibrate described dish continually it is contacted with the inwall of tray salver, data storage face that just may the scratch dish perhaps can stir and accumulate small particle on described dish.
And then, open linearly or close because suppose baffle plate, so box body need be more much bigger than the dish that will store therein.If use tray salver to store the small-sized disc that for example is used for mobile electronic device or portable disc camcorder apparatus, mobile electronic device or portable disc camcorder apparatus itself just must enough greatly just can hold this tray salver so.In addition, the size of a slot of small size tray salver is different from the size of a slot of large scale tray salver usually.Therefore, it is very difficult providing the disk drive that can admit the small size tray salver can admit the large scale tray salver again.Perhaps, the structure of this at least disk drive will very complicatedly could be admitted this dish of two types.

As will be described in detail below, when baffle plate was closed, corresponding dish hold assembly 12a was preferably to the center of dish and the bottom compression plate 100 of disk storage part 10d.Therefore, in disk storage part 10d, be easy to act as most and will coil 100 when dish 100 is pressed onto on first baffle plate 16 by dish hold assembly 12a and fix.The outer ledge of the data storage side 100A of dish 100 preferably contacts with the 4th bossing 16m, and its inside edge preferably contacts with the 3rd bossing 16s, 15s, 11s with first, second simultaneously.In this way, preferably will coil 100 data storage area is exposed in the space of determining between the 4th bossing 16m and first, second, third bossing 16s, 15s, 11s.As shown in Figure 3, in otch 16f, there is not the 4th bossing 16m.Therefore this space does not have complete closed.Yet, can arrive at the data storage side 100A that is clamped in the dish 100 among the disk storage part 10d by otch 16f from the only a few dust of label-side.Also have, holes for clamping 11c is surrounded by first, second and the 3rd bossing 16s, 15s, 11s fully, can prevent that therefore dust from arriving at the data storage area of dish 100 by holes for clamping 11c.And then the data storage area does not contact with first baffle plate 16.Therefore, on the data storage area, can not produce any scratch.
When inserting tray salver 101 in the disk drives, open/close the connecting rod (not shown) preferably moves first baffle plate 16 according to the direction of arrow 16A indication opening device/closing device 16t for what disk drive provided according to the direction of arrow A 1 indication.Then, first baffle plate 16 rotates around holes for clamping 11c along the direction of arrow 16A indication.When first baffle plate 16 rotated, its tooth bar 16r rotated gear 14.As a result, gear 14 and tooth bar 15r engagement drive second baffle 15 whereby.Then, second baffle 15 rotates the direction of rotation of this rotation direction and first baffle plate 16 along the direction of arrow 15A indication around holes for clamping 11c.Along with the rotation of first and second baffle plates 16,15, a slot 11h has just revealed to come out gradually.In this case, first baffle plate 16 preferably is rotated further up to otch 16f with till a slot 11h of cartridge lower shell 11 aligns.On the other hand, the position of two of second baffle 15 end 15y and 15x preferably can be clipped in a slot 11h therebetween.
First and second baffle plates 16,15 when closure or openness not with identical rotational speed.But the rotating speed of first and second baffle plates 16,15 is inversely proportional to the distance between the some 16p of the center of rotation 11q of baffle plate and tooth bar 16r and gear 14 engagements respectively, and the distance between the some 15p that meshes of the center of rotation 11q of baffle plate and tooth bar 15r and gear 14.Therefore, the rotational angle of first baffle plate 16 when closure or openness is different from the rotational angle of second baffle 15 when closure or openness.In this preferred embodiment, the required rotational angle of closure or openness second baffle 15 preferably the required rotational angle of closure or openness first baffle plate 16 1.2-3 doubly.Like this, by rotating just 40-60 degree of opening device/closing device 16t, just can expose or cover a slot 11h as required.
As will be described, when the baffle plate of two closures began rotation and unlatching, dish hold assembly 12a preferably removed from coiling 100 with the rotation of first baffle plate 16.In this way, dish 100 discharges in the middle of the clamping of dish hold assembly 12a, and gets ready for the rotation in disk storage part 10d.However, stretch out from the dish window when moving, will never drop out by dish window 12w so coil 100 owing to dish hold assembly 12a.
In this way, in above-mentioned preferred embodiment, two baffle plates preferably according to opposite mutually direction when synchronous ground rotate.Therefore, even it is very little to rotate the angle of one of two baffle plates, also can produce big opening.Such structure can make this tray salver and large diameter dish compatibility.In other words, this structure can be applied to effectively and be designed in the tray salver that stores the minor diameter dish, but the counterpart of its slot and major diameter tray salver is the same wide.
In addition,, be preferably in disk storage and partly be provided for gear that two baffle plates are interlocked, help to reduce the overall dimensions of tray salver like this according to this preferred embodiment.For this reason, the present invention can be applied in the small-diameter disc cartridge that needs the reduction overall dimensions especially effectively.
Next, opening device/closing device 16t is described.Fig. 5 A and 5B are the planimetric maps of representing near the structure of the part the opening device that the is positioned at it/closing device 16t of tray salver 101 with bigger ratio.Shown in Fig. 5 A, opening device/closing device 16t preferably is connected on the perpendicular wall 16i of first baffle plate 16 by means of an elastic component 16e.Preferably provide bump bonding part 16g in opening device/closing device 16t end.On the other hand, cartridge lower shell 11 preferably is provided with bossing 11g.When baffle plate was closed, the bump bonding part 16g of first baffle plate 16 preferably engaged and locks with the bossing 11g of cartridge lower shell 11.Like this, first baffle plate 16 can not rotate in this state.Also have, because first baffle plate 16 and gear 14 engagements, gear 14 meshes with second baffle 15 again, so second baffle 15 also can not rotate.In other words, baffle plate can remain closed.
For opening baffle plate, need stretch out opening device/closing device 16t according to being directed downwards of arrow 16B indication towards the center of dish.Then, bossing 11g and bump bonding part 16g throw off mutually, thereby continue to move opening device/closing device 16t along the direction of arrow 16B indication.Then, first baffle plate 16 rotates along the direction of arrow 16A indication.Second baffle 15 also begins to rotate by means of gear 14.
Shown in Fig. 4 A and 4B, when baffle plate was closed, opening device/closing device 16t preferably was positioned among the slot 11h.On the other hand, when baffle plate was opened, opening device/closing device 16t preferably was contained among the otch 11k of sidewall 11i of cartridge lower shell 11.Therefore, even during the access head slot 11h of disk drive, opening device/closing device 16t also will never disturb the visit of head.
Below, describing a plurality of dish hold assembly 12a that are dispersed in dish 100 peripheries with reference to Fig. 3,4A, 4B, 6A, 6B is clamping disks 100 how.Fig. 6 A is the sectional view of a dish hold assembly 12a when first and second baffle plates 16,15 cover a slot 11h and clamping disk 100, and described section is to get along the radial direction of dish.On the other hand, Fig. 6 B exposes holes for clamping 11c and a slot 11h and discharges described dish 100 so that coil 100 sectional views that can rotate hour indicator hold assembly 12a in tray salver 101 when first and second baffle plates 16,15, and described section is to get along the radial direction of coiling.
Among the dish hold assembly 12a each is preferably all passed through breach and is partly told from cartridge upper shell 12, thereby can partly stretch among the dish window 12w, and preferably makes the as a whole cartridge upper shell 12 that is connected to by means of elastic part 12e.Preferably arrange a series of such dish hold assembly 12a along the periphery of dish.In this preferred embodiment, preferably provide 3 dish hold assembly 12a.As shown in Figure 6A, the end of each dish hold assembly 12a preferably all is provided with a slope 12b, and slope 12b tilts, and therefore can reach the projection area of dish and the outer ledge top of dish 100.Dish hold assembly 12a preferably can make slope 12b contact with the outer ledge 100c of dish 100, perhaps the outer boundary with dish 100 first side contacts, to coil 100 folders whereby thereon, along thickness direction compression plate 100 by arrow 100t indication, and make dish 100 data storage side 100A (promptly, second side) realizes plane contact with the first, second, third and the 4th bossing 16s, 15s, 11s, 16m, shown in Fig. 4 A.As a result, coil 100 clampings and be fixed on inboard except that the data memory block and the outer ledge of data storage side 100A.Also have, the data storage area of the data storage side 100A of dish 100 is sealing roughly just, also leaves certain clearance between data storage area and sunk part 16b.Therefore, do not have on the data storage area that dust entered or be deposited on data storage side 100A.At this state, the guiding rib 12c that represents with oblique line is what to separate with dish hold assembly 12a, shown in Fig. 4 A.
Closed and coil 100 during by dish hold assembly 12a clamping when baffle plate, the center of dish 100 is preferably consistent with the center 11q of holes for clamping 11c.The center of holes for clamping 11c also is the center of disk storage part 10d.
Shown in Fig. 4 B and 6B, when the baffle plate of two closures begins rotation and unlatching, the guiding rib 16c bossing 12c (representing with oblique line in Fig. 4 B) best and on the corresponding inner surface of dish hold assembly 12a that provides for first baffle plate 16 contacts, and raises dish hold assembly 12a whereby.As a result, dish 100 is released from the clamping of slope 12b, for rotation is got ready.Point at this moment, dish hold assembly 12a also reach in the dish window 12w or reach on the dish window 12w, and are suspended from the part (i.e. Pan outer ledge) of the projection area of dish.Therefore, though in disk drive release dish 100, described disk drive is designed to vertically mounting disc 100, dish 100 can not fall down from tray salver 101 yet.In other words, even supposition is the disk drive of vertically packing into when using tray salver, dish hold assembly 12a also can prevent to coil 100 and fall down by dish window 12w.Randomly, dish hold assembly 12a can be used as integral part and is connected to cartridge lower shell 11 through elastic component.
As previously discussed, contact with guiding rib 16c, can raise dish hold assembly 12a and release dish 100 by the bossing 12c that makes dish hold assembly 12a.Therefore, if regulate position and the girth of guiding rib 16c at dish hold assembly 12a, can be in due course in baffle plate closure or openness operating periods discharges or clamping disk(-sc) 100.Yet should be noted that not every bossing all must contact with guiding rib 16c simultaneously in the middle of the bossing 12c of 3 dish hold assembly 12a.
As previously discussed, dish hold assembly 12a also plays brake component, will prevent that baffle plate falls down by dish window 12w during closure or openness at baffle plate.In above-mentioned preferred embodiment, dish hold assembly 12a is preferably formed as the integral part of cartridge upper shell 13.Therefore, it is very difficult will inserting any dish 100 by dish window 12w again after assembling tray salver 101.For this reason, in this preferred embodiment, the assembly process that is preferably in tray salver 101 will coil 100 puts into the disk storage part.
Below, the structure of the sunk part 16b of first baffle plate 16 is described with reference to accompanying drawing 7-10.According to storing a dish in any one the described tray salver in the above each preferred embodiment of the present invention, expose a side of dish, and this is different with traditional tray salver.Like this, tray salver of the present invention is thinner than traditional tray salver.Also have, owing to show the label side of placing, so whole tray salver can have a good design.
Yet, because expose a side of hypothesis dish in this tray salver, so the user can touch the label side of dish.Therefore, the Cu Xin user label side of platen too fiercely.Like this, such tray salver should the described dish of clamping, even so that can prevent also that in this case the data storage side of coiling is scratched, prevent that perhaps dish itself from deforming.In view of these potential rough sledding, the inventor has carried out deep research in the following areas, promptly for the described dish of clamping and don't must produce any scratch on the data storage side of dish, should form the sunk part 16b of first baffle plate 16 of what shape.
Fig. 7 represents to be used for the clamp structure 59 (being made of the first, second, third and the 4th bossing 16s, 15s, 11s and 16m) of clamping disk 100, an and space that below the data storage area 100d of dish 100, provides, even therefore user's compression plate 100 fiercely, data storage area 100d can not be held structure 59 scratches yet.Should be noted that in Fig. 7 the size of some part of clamp structure 59 is not pro rata, its purpose is to make the feature of the clamp structure 59 that limits described space to be expressly understood.Therefore, the length breadth ratio shown in Fig. 7 is different with actual conditions.
Suppose to allow enough spaces below dish 100, the height in this space only need be slightly larger than the maximum flexion of dish 100.This is because much no matter the deformation of dish 100 has in this case, dish 100 also will never contact with clamp structure 59.Yet the tray salver with so abundant space may be too thick.So, actually, should make the space minimum of dish 100 belows.In order to make this space minimum, should come clamping disk 100 like this, have as far as possible little degree of crook so that coil 100.In order to reduce degree of crook, the various piece that is held structure 59 clampings of dish 100 is preferably as much as possible near the data storage area 100d that coils 100.As shown in Figure 7, preferably be identified for the various piece of clamp structure 59 of the data storage side 100A of supporting disk 100 by inner radial Rin and outer radius Rout.In other words, dish 100 is not only supported by the inside part of the clamp structure 59 of the inboard that is positioned at inner radial Rin, and is supported by the Outboard Sections of the clamp structure 59 in the outside that is positioned at outer radius Rout.Here supposition " inner radial Rin " is from coiling 100 center to any the distance than the center of the more close dish 100 of the inner boundary of data storage area 100d, and this point is near the inner boundary of described data storage area 100d.On the other hand, supposition " outer radius Rout " here is from coiling 100 center to any the distance than the outer ledge of the more close dish 100 of the outer boundary of data storage area 100d, and this point is near the outer boundary of described data storage area 100d.As previously discussed, determine that these two points of inner radial Rin and outer radius Rout will be as much as possible near data storage area 100d.For example, be about 5 inches (that is, radius is about 60mm) as the diameter of fruit tray 100, then inner radial Rin preferably is about 20mm, and outer radius Rout preferably is about 59mm.On the other hand, be about 80mm as the diameter of fruit tray 100, then inner radial Rin preferably is about 20mm, and outer radius Rout preferably is about 39mm.
Preferably be identified for preventing the abrasive space 69b that below dish 100, provides of data storage area 100d according to the following stated mode.At first, determine height (the perhaps degree of depth) S (mm) of space 69b.Next, determine 3 round 69d, 69e, 69f.Specifically, the radius of circle 69d equals outer radius Rout, and determines on data storage side 100A; The radius of circle 69e obtains by (Rout-1.2S), and is to be parallel to data storage side 100A and to be to determine on the plane of 0.3Smm apart from the distance of data storage side 100A; The radius of circle 69f obtains by (Rout-16.2S), and is to be parallel to data storage side 100A and to be to determine on the plane of Smm apart from the distance of data storage side 100A.There is a side surface 59a top and bottom by the frustum of a cone that circle 69d and 69e determine respectively; There is a side surface 59b top and bottom by another frustum of a cone that circle 69e and 69f determine respectively.
Determine a right cylinder in addition, it has the bottom of a circle, and the radius of bottom is counted from 100 the center of coiling and is Rin, and a side surface 59d is arranged, and the height of side surface 59d (or degree of depth) is counted from data storage side 100A and is S.Remove the right cylinder of determining by side surface 58d from the two rank frustum of a cones of determining by side surface 59a and 59b, the space 69b that provides below data storage area 100d just can be provided.
The value of S has been determined the height of space 69b.Therefore, the S value is big more, and 100d abrasive possibility in data storage area is more little, and deformation has taken place also is like this even coil 100.Yet along with the increase of S value, tray salver has also increased its thickness.Like this, for the tray salver that obtains to approach, the value of S is as much as possible little.The inventor found through experiments and confirms: the diameter as fruit tray 100 is 5 inches; the S value is that 0.8mm-1.0mm is just enough big; can do not abraded with the data storage area 100d of protective disc 100 completely, its condition is that the bending of dish 100 is caused by the manual applied pressure of user.The value of S is 1.0mm preferably.We also find: the diameter as fruit tray 100 is 80mm, and the S value is that 0.5mm-0.8mm is just enough big, can not abraded with the data storage area 100d of protective disc 100 completely, and its condition is that the bending of dish 100 is caused by the manual applied pressure of user.
Fig. 8 schematically is illustrated in the space 69b that dish 100 belows provide the S value to be set at 1mm, and the distortion of the condition lower wall 100 of exerting pressure to space 69b on dish 100 has much.The inventor found through experiments and confirms: the user manually will never surpass 3kg to dish 100 applied pressures.The inventor also finds, even when applying maximum pressure 3kg, the bending of dish 100 also fully within the 69b of space, will not touch side surface 59a or 59b.
In this case, the space 69b that limits like this has and prevents to coil 100 data storage area d and do not abraded required minimum dimension.Therefore, below the data storage area 100d of dish 100, just can provide a bigger space.In other words, the space 69b that is provided can exceed side surface 59a and 59b, as shown in Figures 9 and 10.Yet, in this case, for the physical strength of the Outboard Sections that increases clamp structure 59 fully outer ledge with clamping disk 100, be preferably in described Outboard Sections near provide reinforcing section 59 ' or 59 ".Can use effectively side surface 59a and 59b determine these reinforcing sections 59 ' or 59 " the permission shape.
These results show; by designing first and second baffle plates 16 and 15; so that the first, second, third and the 4th bossing 16s, 15s, 11s and 16m and the sunk part 16b that is made of these bossings limit space 69b as shown in Figure 7 below dish 100; even be subjected to the effect of some pressure that the user applies, also can protect the data storage area of the dish 100 in the tray salver 101.
In above-mentioned preferred embodiment, provide a plurality of dish hold assembly 12a, the integral part that makes it stretch to dish window 12w and form box body 10.Yet the dish hold assembly can have any other shape, and can be arranged on any other position, if the dish hold assembly can prevent that dish from dropping out by dish window 12w and can be when baffle plate be closed the described dish of clamping.Even like this, when baffle plate will closure or openness, the dish hold assembly preferably also can clamping or is discharged described dish.For example, can comprise the dish retained part of ring-type according to the tray salver of another preferred embodiment of the present invention, it can stretch to dish window 12w and with first or the second baffle interlocking so that can in disk storage part 10d, move up and down.
Second embodiment
Tray salver according to second certain preferred embodiment of the present invention is described below.Figure 11 is the decomposition diagram of expression according to the tray salver 102 of this second preferred embodiment of the present invention.Figure 12 A and 12B are the planimetric maps of inner structure that the tray salver 102 of cartridge upper shell 12 has been removed in expression, represent state and first and second baffle plates 16 and 15 states of opening of first and second baffle plates 16 and 15 closures respectively.In Figure 11,12A, 12B, use with Fig. 3 in the identical label of label that uses, represent that the corresponding component with the tray salver 101 of the first above-mentioned preferred embodiment has any parts of the tray salver 102 of identical function.
In the tray salver 101 of the first above-mentioned preferred embodiment, dish hold assembly 12a best clamping disk(-sc) 100 is so that 100 the center of coiling is consistent with the center of disk storage part 10d.But in this preferred embodiment, when clamping described dish 100, dish 100 centers of preferably departing from disk storage part 10d.For this reason, tray salver 102 preferably includes the perpendicular wall 16i that coils hold assembly 18, the first baffle plates 16 and preferably is provided with otch 16k.
Shown in Figure 12 A, dish hold assembly 18 is a sheet spring preferably, is made by metal, resin or any other suitable material, and its end preferably is fixed on the cartridge lower shell 11.When baffle plate was closed, dish hold assembly 18 preferably entered disk storage part 10d by the otch 16k of first baffle plate 16, thereby can apply elastic force along the dish 100 of arrow 1C direction in being stored in disk storage part 10d.Shown in Figure 12 A, the radius-of-curvature r1 of the sidewall 12i of disk storage part 10d preferably equals the radius of its center by the disk storage part 10d of the definite circle of a 11q.On the other hand, the radius-of-curvature r2 of regional 10r that locatees the otch 16f of first baffle plate 16 preferably equals to coil the radius of 100 outer ledge.The center of this regional 10r is preferably determined by a 100q.
As shown in figure 13, preferably apply elastic force from the dish 100 in 18 pairs of disk storage parts of dish hold assembly 10d along direction by arrow 1C indication, and coil 100 and preferably be held, so that the outer ledge of dish 100 is contacted with the sidewall 12i of disk storage part 10d in regional 10r so that the center of disk storage part 10d is departed from along direction 1C in its center.In this case, dish hold assembly 18 is platen 100 on direction 1C only preferably, dish 100 can not be pressed to first baffle plate 16.On the contrary, dish 100 can be pressed to first baffle plate 16 by other dish hold assembly 12a ' (following also will be described this).
In the middle of the unlatching baffle plate, baffle plate is preferably realized rotating by move opening device/closing device 16t along arrow 16A direction shown in Figure 12 B.When first baffle plate 16 when direction 16A rotates, the otch 16k of perpendicular wall 16i also moves along equidirectional.Perpendicular wall 16i is very fast to be contacted with dish hold assembly 18, whereby along the direction platen hold assembly 18 opposite with direction 1C.As a result, dish hold assembly 18 separates from coiling 100, stops along direction 1C the dish 100 in the disk storage part 10d being applied elastic force.
When closed baffle plate in this manner, dish hold assembly 18 best clamping disks 100, and dish 100 is departed from respect to the center of disk storage part 10d, thereby the outer ledge that makes dish 100 contact in the otch 16f of location first baffle plate 16 regional with sidewall 12i.In other words, when baffle plate was closed, dish hold assembly 18 was preferred for precalculated position clamping and the shaft collar 100 on a plane that is parallel to dish 100.
14A and 14B description dish hold assembly 12a ' are clamping disks 100 how with reference to the accompanying drawings.Figure 14 A is the sectional view of one of dish hold assembly 12a ' of getting along the radial direction of dish when first and second baffle plates 16,15 cover a slot 11h and clamping disk 100.On the other hand, Figure 14 B is the sectional view of the dish hold assembly 12a ' that gets along the radial direction of dish when first and second baffle plates 16,15 expose a holes for clamping 11c and a slot 11h and release dish 100 it can be rotated in tray salver 102.
