Embodiment
Fig. 3 and Fig. 4 illustrate the state that tray salver according to the preferred embodiment of the invention is decomposed and assembles respectively.With reference to relevant drawings, be used to hold the housing 201 of disc D, be used for the valve 210 that On/Off is formed on the perforate of housing 201 below the disc D, be used for the lid 203 of covering shell 201 upper surfaces, and be installed in the clamping element 240 that lid 203 places seal perforate 203a.
Here, clamping element 240 has the function that is similar to the same clamping disc D of conventional disc driver clamper, and has the function of sealing perforate 203a simultaneously.Just, in present structure, have the element that clamps function and be installed in lid 203 places, be not on disk drives, and have the function of seal and opening 203a simultaneously.This point has detailed description below.
Below, valve 210 is made of the first and second valve parts 211 and 212 that are installed in housing 201 inside, and they can pivot symmetrically.Therefore, when the direction that is separated from each other with them when the first and second valve parts 211 and 212 pivots, perforate 202 (see figure 6) that is opened.And when the first and second valve parts 211 and 212 pivoted with their reverse directions close to each other, perforate 202 was closed (see figure 5).Reference numeral 213 signs are used to make first and second valve 211 and 212 interactional coupling parts.Therefore, when first valve 211 pivoted, second valve 212 pivoted with opposite direction by coupling part 213.Be used for being installed in bottom surface and each the first and second valve parts 211 and 212 places of housing 201 along the torsionspring 204 of closing perforate 202 direction fexible bias pressures, the first and second valve parts 211 and 212.When the power that is applied by all-or-nothing piece 120 was removed, valve 210 was got back to initial off-position.
Form the projection 230 and 220 that contacts with the marginal portion D3 of disc D excircle in the first and second valve parts 211 respectively with 212.Just, disc D is included in the clamp area D1 at inner circumference place, the block of information D2 of recorded information, and the marginal portion D3 that is arranged on the block of information D2 outside.Because the marginal portion D3 as a non-block of information is by projection 230 and 220 supportings, so the contact between block of information D2 and the valve 201 can be avoided. Projection 220 and 230 has inclined surface 221 and 321, and these two surfaces are centroclinal towards the disc D that is held respectively.Therefore, as shown in Figure 5, when the first and second valve parts 211 and 212 were closed, the marginal portion D3 of disc D was supported by the upper end of projection 220 and 230.As shown in Figure 6, when the first and second valve parts 211 and 212 were opened, disc D descended along inclined surface 221 and 231.The disc D that the descends clamp area D1 at circumference place is within it supported by the projection 205 that is formed on housing 201.When valve 210 was closed, disc D was raised and clamping element 240 tight its clamp area of contact D1, as shown in Figure 5.
Equally, supporting member 207 is set at the lower surface of each first and second valve part 211 and 212, just hold the apparent surface on surface, disc D place, thereby in the gathering sill that supporting member 207 can be inserted into be formed in the housing 201 206 and can slide.In the first and second valve parts 211 and 212 pivot processes, the track that gathering sill 206 moves along supporting member 207 and forming.Therefore, in the On/Off operating process of the first and second valve parts 211 and 212, supporting member 207 slides along gathering sill 206.The contact portion 206a that the end 207a that is inserted into the supporting member 207 of gathering sill 206 is directed to groove 206 blocks, as shown in Figure 7.Therefore, when external force is applied on the valve 210 with direction shown in the arrow F, because being directed to the contact portion 206a of groove 206, blocks end regions 207a, so prevent the internal modification of valve 210 towards housing 201.Here, outstanding although end 207a can be formed outside housing, preferably, the holding portion 206b that is connected to gathering sill 206 is formed among the housing 207a, thereby end regions 207a can be projected into outside the outside surface of housing 201, as shown in the figure.
The perforate 203a of clamping part 240 by complete close cap 203 prevents such as the intrusion of the exterior material of dust and clamps disc D as required.As shown in Figure 3 and Figure 4, clamping part 240 comprises: the clamping retainer 241 of supporting perforate 203a marginal portion; Be installed in the yoke (yoke) 242 that clamps on the retainer 241; Above clamping retainer 241, be covered with the lid 243 of perforate 203a fully.Therefore, because perforate 203a is fully sealed by clamping part 240, dust can't be invaded from perforate 203a.In order to change dish, uncap 203 and disc D are substituted by new disc, as shown in Figure 4.When the disc D in the housing 201 is raised, clamp the clamp area D1 that retainer 241 closely contacts disc D, as shown in figure 11.Along with the first and second valve parts 211 and 212 are closed as shown in figure 11, raise at disc D described disc D when inclined surface 221 and 231 is raised.And as shown in figure 10, disc D is raised, when turntable T when perforate 202 enters with executive logging in disk drive/regenerative operation, the disc D that is contained on the turntable T is raised.Here, magnetic attracting force be created in yoke 242 and be installed in turntable T magnet T1 between, this power is exactly the power that clamps disc D.
As shown in Figure 5, valve 210 and lid 203 by the state of Close All under, the tray salver with the disc D that installs therein enters disk drives.Here, dust all passages that can enter box body inside are all sealed.When tray salver enters, as shown in Figure 6, the all-or-nothing piece 120 promotion Lock Part 211b that are installed in the disk drives untie lock hook 211c from lock slots 212b ', and promote to form the locking projection 212b of lock slots 212b ', therefore the second valve part 212 pivots along the clockwise direction among the figure.Then, the first valve part 211 is by being pivoted with counter clockwise direction by coupling part 213 engagements.Therefore, between the first and second valve parts 211 and 212, open perforate 202.But, because the first and second valve parts 211 only contact disc D with 212 projection 230 with 220, and because contact area is restricted to the marginal portion D3 as the disc D of non-block of information, so in the On/Off operating process of valve 201, the block of information of the recording surface of disc D hardly can be destroyed.Along with valve 210 is opened, disc D reduces along the inclined surface 221 and 231 of projection 220 and 230, and is supported by the upper surface of projection 205 and inclined surface 221 and 231 provisionally, as Fig. 6 and shown in Figure 9.In this state, the turntable (not shown) that is used for driving disk of disk drives is through the disc D that perforate 202 enters and 240 clampings of relative clamping element are supported by projection 205 and inclined surface 221 and 231, as shown in figure 10.Then, this turntable rotation and with respect to disc D executive logging/regenerative operation.
On the contrary, when the recording/reproducing operation was finished, this turntable was lowered and the clamping of relative clamping element 240 is removed.The non-block of information D1 of disc D and D3 are by projection 205 and inclined surface 221 and 231 supportings.In this state, tray salver is drawn out of from disk drives, and the first and second valve parts 211 and 212 are got back to their initial position, thereby perforate 202 is closed.Here, the marginal portion D3 that is in disc D excircle is raised along the inclined surface 221 and 231 of projection 220 and 230, gets back to state as shown in Figure 5.Owing to do not carry out the valve shutoff operation under the situation of contact information district D2 at valve 210, so this block of information D2 can keep safety.And in this state, disc D rises along inclined surface 221 and 231, and promotes to support the clamping retainer 241 of the marginal portion of perforate 203a, thereby closely contact covers 243, as shown in figure 11.Just, clamping retainer 241 is clamped at disc D and covers between 243.Therefore, do not move, so can avoid clamping other element collision and consequent noise in retainer 241 and the tray salver such as lid 203 and lid 243 owing to clamp retainer 241.
In valve 210 pent states, because first and second valve 211 and 212 engagement protrusion 211a and mating groove 212a is engaged in together and the end 207a of supporting member 207 is blocked by the contact portion 206a of gathering sill 206, even so when valve 210 inwardly was pressed into housing 201 by perforate 202, valve 210 can not be pushed.Therefore, can prevent distortion, and the closed condition of perforate 202 can keep with being stabilized owing to the valve 210 that external force caused.
Below, Figure 12 to Figure 14 illustrates tray salver according to another embodiment of the present invention.Here, identical designated has the similar elements of identical function.
As shown in the figure, the tray salver of present embodiment has the structure that is similar to previous embodiment.But not such as the perforate 203a in lid 203 ', and clamping part 240 ' is installed in and covers 203 ' inside surface.That is to say, in the present embodiment, owing in lid 203 ', do not form the perforate that dust is invaded at all, so can keep the state of complete closed in a side of lid 203 '.Because lid 203 ' does not have perforate, covers 203 ' inside surface so clamping part 240 ' is installed in.Clamping part 240 ' comprises yoke 242, clamps retainer 241, and is attached to the ring-type element 244 that covers 203 ' inside surface.Described clamping retainer 241 is along with it contacts and supported with the marginal portion of ring-type element 244.
As shown in figure 13, when the tray salver with said structure was loaded in the disk drives and carries out enlightenment/regenerative operation, disc D was clamped at turntable T and clamps between the retainer 241.As shown in figure 14, when tray salver when disk drives unloads, clamp retainer 241 and be clamped at disc D and cover between 203 ' the inside surface.
Therefore, in the tray salver of present embodiment, can avoid dust basically by covering 203 ' intrusion.Other function that comprises the valve On/Off be identical described in the previous embodiment.
