Abstract

A disk cartridge includes a case for accommodating a disk, a cover, installed at the case to be capable of being open and shut and having an open hole formed therein open to the outside, a shutter, installed under the disk in the case to be capable of moving, for opening/shutting an opening hole formed in the case and a clamping member, installed at the cover to seal the open hole, for clamping the disk. Thus, since the clamping member blocks the hole of the cover connected to the outside, the possibility of intrusion of dust into the disk cartridge is reduced. Also, since there is no need to installed the clamping member at the disk drive, the disk drive can be made simplified and slim.

Description

Tray salver

Technical field

The present invention relates to a kind of recording surface that is used to protect the disc that is held and avoid tray salver such as the pollution of dust or fingerprint, this disc is a kind of information recording/regenerating medium.

Background technology

Usually, tray salver is holding the disc as the information recording/regenerating medium, and is installed in the disk drives.As shown in Figure 1, traditional tray salver 100 comprises the housing 101 that is used to hold disc D, be installed in the valve 110 in the housing 101, it can rotate so that open or close the perforate 102 that is formed in the housing 101 selectively, thereby make the pick-up (not shown) of disk drives can visit disc D, and the lid 103 that is fixed to housing 101 tops.Reference numeral 103b indication is formed on the perforate that is used to change dish and clamping in the lid 103.Reference numeral 103a indication is installed in the anti-detachment bar at lid 103 places, and it can slide to prevent that disc D breaks away from by perforate 103b.Therefore, when disc D was mounted, anti-detachment bar 103a was pulled rearward moving, thereby can not interfere disc D.After the installation of disc, anti-detachment bar 103a is pushed forward, and breaks away from by perforate 103b thereby the end of anti-detachment bar 103a prevents disc D.

Shown in Fig. 2 A, when the tray salver 100 that is holding disc D was inserted into disk drives, the all-or-nothing piece 120 that is installed in disk drives promoted Lock Part 111a, thereby made the groove 101a disengagement of the projection 111c of valve 110 from housing 101.Then, this all-or-nothing piece 120 promotion interference piece 111b make valve 110 pivot around left and right pivotal axis 110a.Valve 110 is formed by the first and

second valve parts

111 and 112, and these two parts are installed into respectively and can pivot around left and right pivotal axis 110a, and by 113 engagements of meshing gear part.When the first valve part 111 that is combined with interference piece 111b was rotated in the direction of the clock, the second valve part 112 was rotated by counter clockwise direction, thereby the first and

second valve parts

111 and 112 was separated from each other and perforate 102 unlatchings.Then, the turntable (not shown) of disk drives and clamper (illustrating) enter perforate 102 and perforate 103a to clamp disc D.The recording surface of a pick-up (not looking out) visit disc D is to carry out recording of information and to reproduce operation.Although in the drawings not shown, be used in the drawings with counterclockwise, promptly: be installed between the first valve part 111 and housing 101 bottom surfaces along torsionspring near the direction fexible bias pressure first valve part 111 of perforate 102.When the power that is applied by all-or-nothing piece 120 was removed, this valve 110 was got back to its initial position.

But with above-mentioned structure, dust can be invaded by the perforate 103b of lid 103.Certainly, owing to be not the surface that is used to write down towards the upper surface of the disc D of perforate 103b, so the direct pollution that dust causes can not take place.Yet when dust entered and be trapped on the valve 110, the dust on the valve 110 can adhere on the recording surface of disc D in the on/off operation process.Similarly, if need not to use valve, the recording surface of disc D is possibly by contamination by dust.

In addition, because valve 110 is installed in the housing in 101 and disc D is placed on the valve 110, in the opening and closing operating process of valve 110, the recording surface (Pan lower surface in the drawings) of valve 110 contact disc D, thus the recording surface of disc D can be scratched and destroyed by valve 110.

Be equally in above-mentioned structure, when valve is suppressed by perforate 102 under valve 110 pent states, valve 110 easy deformation.Just,, each first and

second valve part

111 and 112 be supported owing to being coupled into to pivot around pivot 110a at the one end, when the user presses down the other end of valve 110 by perforate 102, and these valve 110 easy deformation.The result who causes is exactly correctly to carry out the On/Off operation.If the On/Off operation is correctly carried out, between first and

second valve

111 and 112, will produce a gap, it can disturb the function as valve.

Therefore, need a kind of improved structure,, can in the recording surface of protection disc, prevent the distortion of valve 110 and the intrusion of dust by this structure.

Summary of the invention

In order to solve the above problems; one object of the present invention is to provide a kind of tray salver through improving; it can prevent that dust from entering into housing; in the On/Off operating process of valve; the recording surface of disc can be protected; and, thereby keep disc more stable because of the valve distortion that external force caused can be prevented from.

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.

Engagement protrusion 211a that is combined together and mating groove 212a are formed on the first and

second valve parts

211 and 212 tight position contacting, as shown in Figure 8.When the first and

second valve parts

211 and 212 closely contact when meanwhile closing perforate 202 each other, compare with 212 separated situations with the first and second valve parts 211, engagement protrusion 211a that is fitted to each other and mating groove 212a have reduced the possibility of doing 210 distortion of time spent valve in external force with direction F.Certainly, described engagement protrusion can be formed on the second valve part 212, and mating groove can be formed on the first valve part 211.

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.

Reference numeral 211b sign is arranged on the first valve part, 211 places and has the Lock Part of lock hook 211c, when perforate 202 was closed, this lock hook 211c flexibly was coupled in the lock slots 212b ' among the locking projection 212b that is formed on the second valve part 212.

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.
