closing plate

5a and 5b are crooked easily can prevent to be pressed the time.

At this moment, the guiding teat 51g of this first opening-closing plate 5a is parked on the end of the guiding recess 55 in this swiveling wheel 4, near the center of swiveling wheel 4.In addition, this first control teat 63 engages with narrow 64a of first cam portion 64 of the second opening-closing plate 5b.In addition, second of this second opening-closing plate 5b control teat 66 engages with the first sweep 68a of second cam portion 65 of this swiveling wheel 4.

When this is operated the power that part 45 overcomes this force-applying member 48, make this swiveling wheel 4 when rotating in the opposite direction with the arrow A side of Figure 17, first opening-closing plate 5a that its guiding teat 51g engages with guiding recess 55, on the arrow B direction of Figure 17, first 52 rotation on this upper shell 6.When this first opening-closing plate 5a pivoted, the second opening-closing plate 5b pivoted round second axle 62a of this first opening-closing plate 5a with respect to the first opening-closing plate 5a on the direction of arrow C.This second opening-closing plate 5b is begun to pivot by narrow 64a driving of this first cam portion 64.On this swiveling wheel 4 first control teat 63 engages with this first cam portion 64.When this second opening-closing plate 5b began to pivot as described above, the first sweep 65a of second cam portion 65 on it on this swiveling wheel 4 of second control teat 66 of joint second opening-closing plate 5b did not put on any revolving force the second control teat 66.

In addition, as shown in figure 18, when this swiveling wheel 4 when rotating in the opposite direction with the side of arrow A, the guiding teat 51g that engages with the guiding recess 55 of this swiveling wheel 4 on the periphery of this swiveling wheel 4, moves to the other end of this guiding recess 55.When this first opening-closing plate 5a pivoted, the second opening-closing plate 5b pivoted round second axle 62a of this first opening-closing plate 5a with respect to this first opening-closing plate 5a on the direction of the arrow C of Figure 17.Then, the first control teat 63 of this swiveling wheel 4 moves to the wider part 64b of this first cam portion 64, and no longer acts on this second opening-closing plate 5b.And the second control teat 66 of the second opening-closing plate 5b moves to the second sweep 65b from this first sweep 65a, and this second opening-closing plate 5b is pivoted on the direction of arrow C.Like this, as shown in figure 18, first and

second openings

24 and 44 are uncovered, and make in the scope of CD 3 between the interior external radius of CD 3 in this swiveling wheel 4 and expose outside.

Shown in Figure 17 and 18, this box body 2 is provided with locking mechanism 71, and this swiveling wheel 4 of its lockable does not rotate it, thereby this first and second opening 24 and 44 is covered by opening-closing plate 5a and 5b.More particularly, shown in Figure 17,18 and 19, this locking mechanism 71 comprises the locking piece 72 that locks this swiveling wheel 4.This locking piece 72 comprises base part 73, forms axis hole 75 on it, and the axle 74 that forms on the inside surface of lower house 7 can pass through this axis hole 75.In addition, also form on this base part 73: lock this swiveling wheel 4 and make the lock part 76 that it does not rotate; Push by inserting directing pin 100, available be formed on release pin on dish register and/or the player separate lock assembly 77; Limit the pivot limiting part 78 of the pivot of this base part 73; With joint the attachment 79 of one end of this force-applying member are arranged.This locking piece 72 is placed near the insertion guide recess 25b of a side of the mating holes 26b that forms on the rear end of this lower house 7.This locking piece 72 is installed on this lower house 7, and the axle 74 on the lower house 7 is then by this axis hole 75.

In addition, when this locking piece 72 was installed on the lower house 7, the free end of axle 74 was outstanding from this base part 73.This outstanding free end of 74 engages with the bearing portions 86 that forms on upper shell 6, preventing that this locking piece 72 is thrown off with axle 74 when being applied with down drop impact etc., and reinforcement just spools 74.

As shown in figure 19, the lock part 76 of this locking piece 72 is towards inside, and it separates lock assembly 77 by the release aperture 80 on the upstanding wall that is formed on this insertion guide recess 25b, moves among this insertion guide recess 25b.In addition, this pivot limiting part 78 abut against with the continuous boss 22 of this upstanding wall in, to limit the pivot of this locking piece 72.

In addition, near the axle 74 of this locking piece 72 is installed, form fixed pin 83, on this pin, force-applying member 82 (for example, torsion-coil spring etc.) is installed, so that on direction, give these locking piece 72 reinforcings.This fixed pin 83 has the spiral part of superincumbent this force-applying member 82 of reeling.An arm portion that is installed in this force-applying member 82 on this fixed pin 83 engages with boss 22, and its other end engages with the attachment 79 of this locking piece, thereby on the locking direction of the arrow D of Figure 17, give these locking piece 72 reinforcings, make this separate the open end that lock assembly 77 is positioned at this insertion guide recess 25b.

The position of the lock part 76 of this base part 73 is inside a little at the periphery of this swiveling wheel 4.This swiveling wheel 4 forms locking recess 84 on the position more inside a little than its periphery, engage with this recess from these base part 73 outstanding lock parts 76.Form on this locking recess 84 and engage concave shaped portion 85.The upstream side of this joint concave shaped portion 85 has vertical wall.Therefore, when this swiveling wheel 4 when rotating in the opposite direction with the side of the arrow A of Figure 17, this lock part 76 engages with this locking recess 84 reliably, the latter's vertical wall is then towards the vertical surface of this lock part 76.This lock part 76 engages concave shaped portion 85 and engages with this, lock this swiveling wheel 4 it is not rotated.As shown in figure 20, receive at this swiveling wheel 4 below the tapering part 42 that the base part along annular protrusion 43 on the side of CDs 3 forms, form locking recess 84.As discussed previously, the periphery edge of these tapering part 42 supporting CDs 3.This locking recess 84 forms dark unlike required.

Locking piece 72 is made by the good synthetic resin of sliding capability (for example aldehyde resin), and it is less to the frictional resistance of lower house 7 and axle 74.

Below, explanation utilizes opening-

closing plate

5a and 5b to cover this first and

second opening

24 and 44 with reference to Figure 17.Force-applying member 82 is given these locking piece 72 reinforcings, and it is rotated round axle 74 on the arrow D of Figure 17 direction.At this moment, this lock part 76 engages with the concave shaped portion 85 that engages of the locking recess 84 that forms on the position more inner than the periphery of this swiveling wheel 4.Therefore, engage, can stop this lock part 76 to pivot owing to engage concave shaped portion 85 with this.Going up in the opposite direction with the side of arrow D even have on this swiveling wheel 4, the power effect that this swiveling wheel 4 is rotated, but also will be added on this lock part 76 in the power of the arrow D of Figure 17 directive effect.Under this power effect, this lock part 76 enters in this joint concave shaped portion 85, and therefore, this locking piece 72 can lock this swiveling wheel 4 reliably, and it is not rotated.

And for example shown in Figure 21, this is separated lock assembly 77 and moves towards the front end opening portion of inserting among the guide recess 25b by release aperture 80, and can push the insertion directing pin 100 that the release pin of register and/or player is coiled in also conduct.More particularly, the bottom of the front end of this insertion guide recess 25b is open.This is separated lock assembly 77 and also moves towards the front end opening portion from the end face 87 of the bottom of this insertion guide recess 25b, and can push also this insertion directing pin 100 as the release pin of dish register and/or player.Because this is separated lock assembly 77 and moves among this insertions guide recess 25b, so can prevent that this dish register and/or player from operating improperly.

As shown in figure 22, in the time of in tray salver 1 insertion dish register and/or player, this release pin is introduced among this insertion guide recess 25b.When also as this insertion directing pin 100 of the release pin of dish register and/or player when the open end of front portion moves to this insertion guide recess 25b, it is at first pushed this and separates lock assembly 77, be close to bottom end face 87 then, qualification can be inserted the position of this insertion directing pin 100 like this.In addition, this insertion directing pin 100 is also removable enters among this insertion guide recess 25b.This insertion directing pin 100 is pushed this and is separated lock assembly 77, until the end face 87 of this releasing parts in abutting connection with the position that limits this insertion directing pin 100.Then, as shown in figure 17, this locking piece 72 overcomes the power of this force-applying member 82, is going up in the opposite direction with the side of arrow D, pivots round axle 74.Therefore, throw off with the concave shaped portion 85 that engages in this locking recess 84 this lock part 76, and relatedly with the rotation of this swiveling wheel 4 move in this locking recess 84.

Suppose that as shown in figure 23 it is W that dish register and/or player have width ₁Release pin 88, and the width of this insertion guide recess 25b is W ₂, W ₁〉=W ₂/ 2.Like this, this insertion directing pin 100 can be pushed this reliably and be separated lock assembly 77.

Before pack into this dish register and/or player, be in the state shown in Fig. 1,2 and 17 as the tray salver 1 of above-mentioned structure.More particularly, when this a pair of opening-closing plate 5a and 5b cover this first and second opening 24 and 44, this swiveling wheel 4 is in by force-applying member 48 reinforcings, and in the position that the direction of the arrow D of Figure 17 is rotated, and this is operated the lateral edges place that part 45 is positioned at this first opening 24.As shown in figure 11, be operated the coupling recess 45c of part 45 and near this second opening 44 at this, the coupling recess 50 that forms on this swiveling wheel 4 cooperates, and is moving up or down to prevent this first opening-closing plate 5a.In addition, the first second side edge 51b that opens and closes part 51 is connected with second tapering part that opens and closes the first side edge 61a of part 61 in direction, and the tapering part of the 3rd lateral edges 51c of this first switching part 51, going up in the opposite direction with this side, be connected with this second tapering part that opens and closes the second side edge 61b of part 61.That is to say that in tray salver 1, opening-closing plate 5a and 5b overlap, and are not easy flexural deformation, can prevent that opening-closing plate 5a is upwards moving, thereby can prevent that dust etc. from invading in the box body 2.

At this moment, the guiding teat 51g of this opening-closing plate 5a is positioned near the end in center of the guiding recess 55 of this swiveling wheel 4.In addition, this first control teat 63 engages with narrow 64a of first cam portion 64 of the second opening-closing plate 5b.In addition, second on second opening-closing plate 5b control teat 66 engages with the first sweep 65a of second cam portion 65 on this swiveling wheel 4.Like this, as shown in Figure 2, on this tray salver 1, first opening 24 of lower house 7 is packed.In addition, even push this first opening-closing plate 5a, the restriction teat 51h of this first opening-closing plate 5a can not be close to the zone at the inside radius place of the CD 3 that does not have recording information signal, and this first switching part 51 does not contact the signal record zone of CD 3, therefore, can prevent that the signal record zone is damaged.

In addition, when opening-

closing plate

5a and 5b cover this first and

second opening

24 and 44, the lifting device 14 of these swiveling wheel 4 quilts on upper shell 6 is towards lower house 7 liftings, make the teat 27 that forms along the periphery edge of this first opening 24 engage, thereby can prevent in the intrusion box body 2 such as dust with the first recess 51f that opens and closes part 51.
