[coupling operation of tray salver and separate operation]

The coupling operation and the separate operation (referring to Figure 15 to Figure 27) of tray salver 1 will be described below.

The state (referring to Figure 15 to Figure 16) of first housing 3 and 4 couplings of second housing at first will be described.

First housing 3 and second housing 4 are coupled to the base surface part 7 and the base surface part 42 of base body 5, thereby in vertical direction against each other.

Under the state of first housing 3 and the coupling of second housing 4, first housing 3 and second housing 4 by locking lever 21 and 21 and lock slide 31 and 31 lock.

Locking lever 21 and 21 is positioned at the hub switch side (referring to Figure 15) of locking projections 23a and 23a on the direction (outside direction) that the bias force by bias spring 30 and 30 is separated from each other it; Locking projections 23a and 23a are inserted among the first locking recess 45a and the 45a and engage, and these first locking recesses are formed at the side surface portion 43 and 43 places of second housing 4 respectively.At this moment, the first locking recess 45a and 45a are seamlessly sealed by locking projections 23a and 23a.

Volute spring 36 and 36 bias force make lock slide 31 and 31 be positioned at the tache motorice (referring to Figure 15 and Figure 16) in the place ahead; Lock part 33 and 33 is inserted among the second locking recess 45b and the 45b and engages, and these second locking recesses are formed at the side surface portion 43 and 43 places of second housing 4.

First housing 3 be coupled as stated with second housing 4 and the spring section 49b that locks, make disc recording medium 100,100... to be supported under the state in the housing main body 2 to promote spring 49 and 49b respectively pressurized contact (referring to Figure 15) with the part of the neighboring of disc recording medium 100,100....At this moment, in support slot 45,45..., the neighboring the zone that curved surfaces part 47 and 47 places except side surface portion 43 and 43 of disc recording medium 100,100... form is positioned at regular (regular) position in housing main body 2.

Be positioned at disc recording medium 100,100... under the state of regular position, the regulon 20b of the header board 20 that install at the regulon 15b of the outer wall 15 that install at reinforcing section 10 places of first housing 3 or secondary base 6 places is positioned near the rear end side zone of neighboring of disc recording medium 100.In addition, near the front zone of the adjusting surface 29a that forms respectively of locking lever 21 and 21 balance portion 25 and 25 places and the 29a neighboring that is positioned at disc recording medium 100.

Therefore; Even because the vibration or the impact that apply to tray salver 1 make disc recording medium 100,100... from its position skew; The position of disc recording medium 100,100... also receives regulon 15b, regulon 20b or regulates the adjusting of surperficial 29a and 29a, thereby the state that it is positioned is supported.

In addition, under the state of first housing 3 and the coupling of second housing 4, the bias force that locking lever 21 and 21 latch- release part 24 and 24 are biased spring 30 and 30 is pressed to the insertion portion 41 of On/ Off panel 37 and 41 inclined surface 41a and 41a from rear side.At this moment, inserting protruding 27 and 27 is inserted into the patchhole 37a and 37a of On/Off panel 37 from rear side respectively.

As stated; In tray salver 1; Because the insertion of locking lever 21 and 21 protruding 27 and 27 is inserted respectively among the patchhole 37a and 37a of On/Off panel 37; So dust or moisture can not easily get into housing main body 2 from the outside, housing main body 2 has high-seal property, and data recorded can be guaranteed good preservation state among disc recording medium 100, the 100....

In addition; Has arcuate shape respectively owing to insert the left and right sides surface 27b and the 27b of convexity 27 and 27 based on the central axis that receives support section 22 and 22; So when locking lever 21 and 21 pivots, insert protruding 27 and 27 and can be easy to from patchhole 37 and 37 insertions and taking-up.In addition; Because side surface 27b and 27b have the arcuate shape based on the central axis that receives support section 22 and 22; So be inserted under the state of patchhole 37a and 37a in insertion protruding 27 and 27; Regardless of the pivot position of locking lever 21 and 21, housing main body 2 can be guaranteed good sealing property.

In addition, insert protruding 27 and 27 and can have the tapering shape, its profile diminishes towards front end gradually, and is shown in figure 17.Be designated as through the insertion protruding 27 and 27 of will form for institute and have the tapering shape, the rear openings edge of patchhole 37a and 37a is arrived in the neighboring of inserting convexity 27 and 27 easily close attachment, and the sealing of housing main body 2 can further be improved.

In addition; For tray salver 1; Under the state of first housing 3 and 4 couplings of second housing; Lock part 23 in the locking lever 21 and 21 and 23 locking projections 23a and 23a are inserted among the first locking recess 45a and 45a that forms in the side surface portion 43 and 43 of second housing 4, and the first locking recess 45a and 45a are by locking projections 23a and 23a sealing.

Therefore, the sealing in the housing main body 2 can further be improved.

In addition; Because being formed, the locking projections 23a of lock part 23 and 23 and 23a have the tapering shape; So locking projections 23a and 23a be the edge of opening of close attachment to the first locking recess 45a and 45a easily, the sealing in the housing main body 2 can further be improved.

In addition, locking lever 21 and 21 can form the insertion recess 38a of On/Off panel 37 and the upper and lower surfaces of 38a and all be preferably the inclined surface that forms with the guiding surface form respectively along the axially-movable of back shaft 13 and 13.Like this, locking lever 21 and 21 can more easily insert locking recess 38a and 38a.

Under the state of first housing 3 and 4 couplings of second housing, the centrepin 11 that is installed on first housing, 3 places is inserted among the center pit 100a of disc recording medium 100,100..., the 100a....At this moment, the inside surface of the faceplate part 38 of On/Off panel 37 closely is positioned at the front end place of disc recording medium 100,100....

For tray salver 1, set following size relationship (referring to Figure 18).In addition, for the ease of describing, Figure 18 is the concept map that the state that disc recording medium 100 exerted pressure by centrepin 11 backward is shown.

Difference between the diameter D2 of the diameter D1 of centrepin 11 and the center pit 100a of disc recording medium 100 is set as A; Difference between the diameter of a circle D3 that adjusting surface 29a that installs respectively from the latch- release part 24 and 24 of locking lever 21 and 21 and 29a extend and the diameter D4 of disc recording medium 100 is set as B, and the difference when disc recording medium 100 is exerted pressure by centrepin 11 backward between the inside surface of the neighboring of disc recording medium 100 and On/Off panel 37 is set as C.

At this moment, for tray salver 1, be provided with the size relationship of C＞A＞B.

Therefore; Position at disc recording medium 100 takes place to lose under the accurate situation with respect to the state that is placed in regular position (referring to Figure 15); The adjusting surface 29a of the neighboring of disc recording medium 100 and latch- release part 24 and 24 and 29a are owing to minimum range difference B comes in contact, so its position is regulated.

In addition; Even applying big impact or the like to tray salver 1, causing under the situation of big positional misalignment or deformation for tray salver 1 or disc recording medium 100; The inside circumference of disc recording medium 100 and centrepin 11 are also owing to the range difference A littler than C comes in contact, so the position of disc recording medium 100 is regulated.

Under the situation of the position deviation that disc recording medium 100 takes place as stated; The position of disc recording medium 100 receives the adjusting of regulating surperficial 29a and 29a; Perhaps the position of disc recording medium 100 receives the adjusting of centrepin 11, makes the neighboring of disc recording medium 100 not come in contact with the inside surface of the faceplate part 38 of On/Off panel 37.

Therefore, when first housing 3 moves upward, makes first housing 3 when second housing was opened in 4 minutes with respect to second housing 4, faceplate part 38 does not come in contact with the neighboring of disc recording medium 100, can prevent that disc recording medium 100 is damaged or damages.

In addition; In tray salver 1; Except receiving support section 22, lock part 23 and latch-release part 24; Balance portion 25 also is installed to the locking lever 21 of first housing 3 and the locking of second housing 4, through balance portion 25 is installed being centered close to of locking lever 21 is received near center or its of support section 22.

Therefore, when when housing main body 2 applies big impact, for example when tray salver 1 was dropped by error, locking lever 21 and 21 was not easy to pivot owing to this impact, and the locking of couple state can not removed.Even when applying big impact as stated; Locking can be not non-yet institute remove with desiring, so can be kept at data recorded in the disc recording medium 100 and not make disc recording medium 100 destructions of wherein holding under the good state and from housing main body 2 ejections.

In addition, because near being centered close to the center that receives support section 22 or its, of locking lever 21 so can alleviate for the load of bias spring 30 and 30.In addition, even under housing main body 2 situation that long and disc recording medium 100,100... along continuous straight runs are preserved in vertical direction, also can alleviate for bias spring 30 with 30 load identically.

In addition; Because adjusting surface 29a and 29a that the position of disc recording medium 100 is regulated are formed at the balance portion 25 and 25 places of locking lever 21 and 21 respectively, also can reduce the number of assembly so can prevent the position deviation of disc recording medium 100.

In addition, because balance portion 25 has along the curved surfaces shape of the neighboring of disc recording medium 100 with surperficial 29a of 25 adjusting and 29a, so can improve the bearing accuracy of disc recording medium 100.

In addition, for tray salver 1, be inserted among the center pit 100a, 100a... of disc recording medium 100,100... with the centrepin 11 of the position of regulating disc recording medium 100,100... and be installed to housing main body 2.Therefore, when first housing 3 and 4 couplings of second housing, the position of disc recording medium 100,100... is also regulated simultaneously, makes that the position of disc recording medium 100 can be regulated simple and reliablely.

First housing 3 and second housing 4 by the state that is coupled as stated and locks under, locking lever 21 and 21 lock part 23 and 23 partly are inserted into respectively among the insertion recess 38a that forms in the faceplate part 38 of On/Off panel 37 and the 38a (referring to Figure 15 and Figure 17).Therefore; When housing main body 2 applies big impact, for example when tray salver 1 is dropped by error, because the motion of lock part 23 and 23 receives the adjusting of inserting recess 38a and 38a; So locking lever 21 and 21 is not easy to come off, prevented that back shaft 13 and 13 from damaging.Therefore, can be kept at data recorded in the disc recording medium 100 and do not cause disc recording medium 100 to destroy under the good state and eject from housing main body 2.

In addition; Because locking lever 21 and 21 is arranged in the front side that faceplate part 38 forms the zone of inserting recess 38a and 38a, thus in the side surface portion 43 and 43 of second housing 4 along fore-and-aft direction form respectively first lock recess 45a and 45a width can be reduced.Therefore, can insert disc recording medium 100 the dish insertion/taking-up hole 4a of second housing 4 or prevent that when it takes out disc recording medium from opening in 100 minutes.

In addition; Spring support section 13a and 13a support that bias spring 30 and 30 spiral part 30a and 30a are installed by base surface part 7 places of back shaft 13 and 13 respectively; Arm portion 30b and 30b are supported by the carbine protruding 14 and 14 that base surface part 7 is installed respectively, and another arm portion 30c and 30c are respectively by spring support protrusion 23b that gives prominence to towards the base surface part 7 of locking lever 21 and 21 and 23b support.

Therefore, bias spring 30 and 30 Zone Full are all arranged along base surface part 7, can be reduced size through the inner space of effectively utilizing housing main body 2.

In addition, in tray salver 1, under the state that locking lever 21 and 21 is supported by back shaft 13 and 13 respectively, the convexity that is mounted 39 and 39 of On/Off panel 37 is respectively installed to back shaft 13 and 13.

Therefore, can prevent that back shaft 13 and 13 from coming off by the convexity that is mounted 39 and 39.

In addition, for tray salver 1, the position of being installed to convexity 39 back shaft 13 and 13, that be mounted and 39 respectively is located adjacent one another, and is relative with locking lever 21 and 21.

Therefore, can prevent locking lever 21 and 21 and bias spring 30 and 30 from back shaft 13 with opened in 13 minutes, simultaneously, locking lever 21 and 21 axial the moving along back shaft 13 and 13 can receive adjusting and operate with 21 circle to optimize locking lever 21.

Under the state that first housing 3 and second housing 4 are coupled as stated, for example, tray salver 1 is by box insertions/the taking-ups hole (not shown) insertion from disc changer, and by the latch-release mechanism that is installed to disc changer 70 supports.

Shown in figure 19, latch-release mechanism 70 for example constitutes through following assembly is installed: these assemblies are required towards the rectangular plate shape support base 71 of vertical direction.

Remove pressing piece 72 and 72 and be installed to the leading edge of support base 71, these are removed, and pressing piece is given prominence to downwards and the position is spaced apart from each other along left and right directions.Remove pressing piece 72 and comprise coupling part 72a and exert pressure part 72b, coupling part 72a is from support base 71 extensions and towards fore-and-aft direction, and the lower limb of the part of exerting pressure 72b 72a from the coupling part is outstanding backward.

Outstanding downwards latch- release spare 73 and 73 is installed in the position of rear end side of the left and right edges of support base 71 respectively.Latch-release spare 73 comprises coupling part 73a and removes part 73b that coupling part 73a removes the lower limb of part 73b 73a from the coupling part and inwardly gives prominence to from support base 71 extensions and towards left and right directions.

Outstanding downwards auxiliary member 74 and 74 is installed in the position of front of the left and right edges of support base 71 respectively.Auxiliary member 74 comprises coupling part 74a and insertion portion 74b, and coupling part 74a is from support base 71 extensions and towards left and right directions, and the lower limb of insertion portion 74b 74a from the coupling part inwardly stretches out.

Shown in figure 20; If tray salver 1 inserts from the box insertion/taking-up hole of disc changer, then releasing pressing piece 73 in the latch- release mechanism 70 and 73 releasing part 73b and the insertion portion 74b and the 74b of 73b and auxiliary member 74 and 74 are inserted into respectively among insertion groove 2a and the 2a.

In addition, if tray salver 1 inserts from box insertion/taking-up hole, then the releasing pressing piece 72 in the latch- release mechanism 70 and 72 exert pressure part 72b and 72b are inserted into respectively among the patchhole 37a and 37a of On/Off panel 37 (referring to Figure 21 and Figure 22).

Be inserted among the patchhole 37a of On/Off panel 37 if remove the part 72b that exerts pressure of pressing piece 72, then the insertion of the latch-release part 24 of locking lever 21 protruding 27 is by the part 72b that exerts pressure exert pressure backward (referring to Figure 23 and Figure 24).At this moment; Because the inclined surface 27a that tilts along left and right directions is exerted pressure with respect to fore-and-aft direction by the part 72b that exerts pressure; Locking lever 21 pivots so inclined surface 27a slides with respect to the part 72b that exerts pressure smoothly, and load is not easy to be applied to releasing pressing piece 72 along the pivotal orientation of locking lever 21.

The part of exerting pressure 72b makes locking lever 21 overcome the bias force of bias spring 30 and pivots; The locking projections 23a of lock part 23 takes out from the first locking recess 45a of second housing 4, has removed first housing 3 that caused by locking lever 21 and the locking between second housing 4.When having removed first housing 3 that causes by locking lever 21 and the locking between second housing 4; The adjusting surface 29a of balance portion 25 moves to respect to the neighboring of disc recording medium 100 and loses accurate position, and the adjusting of regulating the 29 pairs of disc recording mediums 100 in surface is disengaged.

In addition; If latch-release spare 73 is inserted among the insertion groove 2a; And the support section 32 that receives of lock slide 31 is exerted pressure by removing part 73b; Then lock slide 31 bias force that overcomes volute spring 36 moves backward, and lock part 33 breaks away from (referring to Figure 25) from the second locking recess 45b of second housing 4.If lock part 33 breaks away from from the second locking recess 45b; The locking that is then caused between first housing 3 and second housing 4 by lock slide 31 is disengaged, and locking between 31 pairs first housings 3 of sliding part and second housing 4 unlocks when locking lever 21 is disengaged for the locking that causes between first housing 3 and second housing 4.
