Description

The structure of carrier

Technical field

The present invention relates to carrier mechanism.Be described in further detail, the present invention relates to be arranged at the carrier mechanism on the Disk replacer etc. of CD player, DVD player.

Background technology

As CD player, DVD player, have a kind ofly deposit a plurality of discs, from wherein selecting the regenerate player of (broadcast) of 1 disc.The player of related model has the disc change apparatus that can deposit many discs simultaneously.The disc change apparatus has a plurality of carriers that put disc, when disc is regenerated, from deposit position with mounting need the carrier conveyance of disc of regeneration to play position.

At deposit position, with the carrier that put disc many ground and row arrangement up and down.Each carrier is along horizontal arrangement, straight by this, flatly be drawn out the back by conveyance to play position.Disc flatly puts with respect to carrier.

In play position, turntable puts the disc on carrier and it is promoted from following support, be clamped in be configured in the top and clamper between.After turntable and clamper are clamped disc, make disc revolution beginning regeneration of disc by turntable.

As shown in Figure 7, in play position 101, make the part of disc 102 overlapping on the disc 102 of deposit position 103.The disc 102 of regeneration need not be pulled out between the disc 102 of deposit position 103 fully, and one is overlapped, shorten the interval of deposit position 103 and play position 101, shorten the depth size of disc change apparatus.

The revolution posture of the disc 102 in the player is shaken, and need set in advance enough interval Ga, Gb between the member thereon.Disc 102 in the player is promoted by not shown turntable, and the carrier 104 that puts between, promptly transferring of the disc in player 102 is provided with sufficient interval.In addition, strengthen the disposition interval P of the carrier 104 of design deposit position 103 each layers to a certain degree, disc 102 in player and being loaded onto thereon between the disc 102 of carrier 104 of layer, promptly the disc in player 102 above sufficient interval Ga is set.That is, make the carrier 104 of each layer leave configuration up and down fully and enlarge the interval of disc 102 up and down, avoid the interference between the disc 102 on disc 102 in the player and its upper strata.

Yet, because carrier configured separate 104 about, put the size maximization of above-below direction of the puller of carrier 104.Especially, the size of the above-below direction of puller maximizes more remarkable in the CD player.Promptly, because the CD player need make 2 kinds of discs of size (disc of the disc of diameter 12cm and diameter 8cm), 102 regeneration, therefore, on carrier 104, need to form 2 layers recess, specifically in the recess that the major diameter disc is used, need further to form the recess that the minor diameter disc is used.For this reason, the thickness of the above-below direction integral body of carrier 104 thickens, and significantly maximizes in the size of the above-below direction that makes relevant carrier 104 overlapping many and the puller that puts up and down.

The object of the invention be to provide avoid with player in disc when disturbing mutually, block disc at interval, the carrier mechanism that can deposit.

Disclosure of an invention

In order to reach this purpose, the invention provides a kind of carrier mechanism, in position that mounting has a plurality of carriers of disc to be in to deposit, select wherein 1 to move and and disc change apparatus that play overlapping with the disc that is arranged in deposit position to play position, the disc that will be in described deposit position and be arranged in the disc upside of broadcast tilts to put to the direction of the disc that leaves broadcast, with the part that tilts with described carrier attenuate.

Disc in being conceived to now play and with it the disc of the deposit position of equitant last layer (hereinafter referred to as the upside disc) describe.In case tilt at the deposit position disc, for the disc in playing, the interval of lap enlarges.On the contrary, if keep the interval of certain lap, the upside disc that tilts with this part close following one deck in ground that just can wholely descend.That is, guarantee still between disc in broadcast and the upside disc that under the state of sufficient room, the interval that can block carrier is configured.

In addition, on the basis of above-mentioned carrier mechanism, the outer peripheral edges of the straight line that the disc center of described deposit position and the disc center of described broadcast couple together and the disc of described broadcast intersect the point of formation as overlapping intersection point, form disc and tilt to use the support portion, to being supported near the position of described play position near described deposit position and from the disc center of described deposit position of disc from this overlapping intersection point.

Suppose that the carrier that puts the upside disc supports this upside disc in the direction position of leaving play position from its center (with the position of play position opposition side), then this upside disc tilt to make and play in the lap of disc reduce.For this reason, the disc direction of lap in leaving broadcast of upside disc tilted.

In addition, suppose that the carrier that puts the upside disc is supporting this upside disc from its overlapping intersection point near the position of play position, the lap of this upside disc just is raised.That is, the upside disc is tilted, but can not make the whole close lower floor that descends of upside disc this moment.

In the present invention, owing on carrier, form the center of leaving the upside disc near play position and leave the disc that overlapping intersection point supported near the position of deposit position and tilt to use the support portion, tilt to support the upside disc with the support portion and make it with this disc, therefore can make the upside disc tilt will be opposite with this lap part reduce.For this reason, the interval of not shortening lap just can make that the upside disc is whole to descend near lower floor's configuration.

The form that invention is implemented

Below the optimal morphology shown in reference to the accompanying drawings describes structure of the present invention in detail.

Fig. 1 ~ shown in Figure 6 is an example that is fit to the example of carrier structure of the present invention.The structure of this carrier is, there are a plurality of carriers 2 of disc 1 to be in deposit position 3, select wherein 1 to move and and disc change apparatus 5 that play overlapping in mounting with the disc 1 that is arranged in deposit position 3 to play position 4, make be in deposit position 3 and play in the direction of the disc 1 of upside disc 1 in leaving broadcast of disc 1 tilt to put, with the part that tilts with described carrier attenuate.

This disc change apparatus 5 has a plurality of carriers 2 in puller 6, put disc 1 and can deposit many discs 1 by 11 ground on each carrier 2.Each disc 1 is stored at deposit position 3 places.And, when disc 1 is play (regeneration), with the carrier 2 that put the disc 1 in the broadcast from deposit position 3 to play position 4 conveyances.In addition, when releasing disc 1, each puller 6 arrives release location 7 with carrier 2 conveyances.In this example, carrier 2 has 3.But the number of carrier 2 is not limited in 3 certainly.

Shown in Figure 2 is carrier 2.On carrier 2, for example in the recess 8 of major diameter disc (Mini Disc of diameter 12cm) usefulness, further form the recess 9 of minor diameter disc (Mini Disc of diameter 8cm) usefulness.The major diameter disc is made of surface level 8a and dip plane 8b with the bottom surface of recess 8. Dip plane 8b 8a inclination with respect to the horizontal plane is 3.85 degree for example.In addition, on the bottom surface of minor diameter disc, be formed with the 1st dip plane 9a and the 2nd dip plane 9b with recess 9.The relative surface level 8a inclination of the 1st dip plane 9a is 1.2 degree for example.And the relative surface level 8a inclination of the 2nd dip plane 9b is 6.6 degree for example.In addition, the window 10 that on carrier 2, is formed with not shown panoramic table and the regenerating unit of acoustic pickup etc. is passed through.

On carrier 2, form the disc of disc 1 inclination that puts is tilted with support portion 11.Disc tilts with support portion 11 as shown in Figure 3 in the vertical view of disc 1, with respect to the center O a of the disc 1 of deposit position 3 with the straight line L that coupled together of the center O b of the disc 1 in playing, and the point that the outer peripheral edges of the disc 1 in will playing will be reported to the leadship after accomplishing a task is as overlapping intersection point Op, with leave this overlapping intersection point Op near deposit position 3 and the center O a of disc 1 that leaves deposit position 3 near relative formation of position (zone) A1 of play position 4.In this example, tilt with support portion 11 as disc, be respectively arranged with the disc that disc inclination support portion 11 that the major diameter disc uses and minor diameter disc use and tilt with support portion 11.In addition, each disc tilts to clamp straight line L and be set at both sides with support portion 11.

Form a plurality of wheel hubs 12 at the major diameter disc of carrier 2 with the bottom surface periphery of recess 8 in addition.The height of each wheel hub 12 tilts high more with support portion 11 more near disc.Support major diameter disc 1 by tilting with support portion 11 and each wheel hub 12, thereby can make this major diameter disc, prevent the sliding injury of disc 1 etc. from the bottom emersion of major diameter disc with recess 8 by disc.

In the carrier 2 of this structure, the thickness attenuation of its above-below direction integral body can be shortened the disposition interval P of levels.Shown in Figure 4 is plays the situation of disc 1 of the carrier 2 of the 2nd layer (from beginning the 2nd down).The 2nd layer carrier 2 from deposit position 3 by conveyance to play position 4.In addition, the 2nd layer disc 1 is mentioned by not shown panoramic table.For explanation simply, Fig. 4 has omitted the description of minor diameter disc with recess 9.

Disc (the 3rd layer the disc of (the 2nd layer disc) 1 of the disc in being conceived to play and an overlapping with it upper strata (top layer) deposit position 3.Hereinafter referred to as the upside disc) 1 describe.In case carrier tray sheet 1 on carrier 2, disc inclination support portion 11 just make disc 1 tilt.Now, as shown in Figure 5, in the vertical view of overlapping intersection point Op and disc 1, be provided with disc tilts with support portion 11 in the position of leaving distance X op, when tilting by this disc to make the words of upside disc 1 tilt angle theta with support portion 11, at overlapping intersection point Op, the interval Ga between the disc 1 in upside disc 1 and the broadcast extends with distance Y.

Thereby, when making upside disc 1 tilt angle theta, even if upside disc 1 integrally dropping distance is Y, promptly, even if near the 2nd layer carrier 2, the interval Ga between the disc (disc in the broadcast) 1 of 1 and the 2nd layer of the 3rd layer the disc (upside disc) of overlapping intersection point Op does not change the 3rd layer carrier 2 yet with distance Y.

This situation is same for the carrier 2 of the 2nd layer and the 1st layer.Thereby it disposes at interval the carrier 2 of each layer can be blocked (dwindling disposition interval P).For this reason, make carrier overlapping and can shorten the short transverse size of the puller 6 that puts about in the of 2, can make 5 miniaturizations of disc change apparatus.In addition, owing to can shorten the short transverse size of puller 6, so can satisfy the apparent requirement of disc change apparatus 5 of the short transverse size of desire shortening puller 6.

Because disc tilts and supporting upside disc 1 from its center Oa near the position of play position 4 with support portion 11, therefore, upside disc 1 raises overlapping side and tilts.In addition, disc tilts and is supporting upside disc 1 from its overlapping intersection point Op near the position of deposit position 3 with support portion 11, therefore, can make upside disc 1 whole decline under the state that overlapping side rising is tilted.That is, can make carrier 2 whole attenuates, can make each layer carrier 2 block it and dispose at interval.

In addition, as shown in Figure 6, at overlapping intersection point Op, minor diameter disc 1s be inclined to play in disc 1 between the equating of interval Ga and major diameter disc 1b, about major diameter disc 1b, because of the interval Ga among the overlapping intersection point Op is designed to fit value, therefore, about minor diameter disc 1s, its interval Ga also becomes optimum value.Especially, the carrier of accepting 2 kinds of discs of size has the tendency that thickens, and carrier of the present invention 2 can make its reduced thickness as mentioned above.For example, accept the carrier of 2 kinds of discs of size, promptly have the thickness of the carrier 2 of 2 kinds of

recesses

8,9, be the carrier that the disc level is put, and can make and the identical thickness of carrier that is merely able to accept a kind of disc.

The disc of the downside of the disc 1 in the broadcast (the 1st layer disc) is tilted configuration equally also, disc 1 in the broadcast is raised from carrier 2, in addition, even if the disc 1 of deposit position 3 is tilted, the disc 1 of downside can not tilt to such an extent that collide, so can not disturb the disc 1 in the broadcast yet with the carrier 2 on its upper strata.

Described form is an example of preferable form of the present invention, but is not limited thereto, and implements as long as can carry out various deformation in the scope that does not break away from main idea of the present invention.For example, in described explanation, be to be example with the carrier 2 that carries 2 kinds of discs 1 of size, certainly, even it is also passable to accept the carrier 2 of a kind of disc 1.

As mentioned above, the structure of the carrier of technical scheme 1 is, is in deposit position and tilts to put in the direction of the disc of disc in leaving broadcast of the disc upside of playing owing to make, and makes the carrier attenuate with the part that tilts, thereby, can shorten the disposition interval of carrier.For this reason, can shorten the short transverse size of the puller that puts carrier, promptly can the attenuate puller, can make the Disk replacer equipment miniaturization.In addition, outstanding puller gives the apparent requirement of the disc change apparatus of attenuate in the time of meeting desire disc is released.

In addition, in the structure of the carrier of technical scheme 2, owing to show in the view bowing of disc, with respect to the disc center of deposit position with the straight line that couples together of the center of the disc in playing, and the point that the outer peripheral edges of the disc play are reported to the leadship after accomplishing a task is as overlapping intersection point, form disc and tilt to use the support portion, supported near the position of play position near deposit position and the disc center of leaving deposit position leaving this overlapping intersection point.Therefore, only disc is put disc is tilted.
