Below, with reference to accompanying drawing embodiments of the present invention are described.

Fig. 1～Fig. 4 represents the 1st embodiment of disk loading device of the present invention, and Fig. 1 is the oblique view of the device that makes disk K regeneration seen from above.On master carrier 1, can pallet 2 be installed with moving freely along the A-B direction, recess that form to place disk K is on pallet 2.This pallet 2 is last supportings of guide rail 1a that are embedded in the side bending formation of master carrier 1 by the ditch 2a that will form on the pallet side.Be installed with on master carrier 1 and make disk K driving, the rotating disk 3 of regeneration and the secondary carriage 5 of acoustic pickup 4, the one end can free C-D direction in figure be bearing on the master carrier 1 rotationally.Disposing the cylinder 6 that has spiral goove on the master carrier 1, the other end of secondary carriage 5 is inlaid in this spiral goove, secondary carriage 5 is being rotated along the C-D direction by making cylinder 6 revolutions.

As shown in Figure 1, pallet 2 can be in the drawings withdraws between the reproduction position of representing with double dot dash line among position and the figure along the A-B direction, back and forth transports with moving freely with what solid line was represented.Represent this displacement with L.On reproduction position, the center P of disk is positioned at the center of rotating disk 3.Under this state, secondary carriage 5 makes it rotate along arrow D direction by the effect of cylinder 6, thereby make acoustic pickup 4 near disk K, carry out the regeneration action of disk, the recorded information on the regeneration disk K.

Fig. 2 represents the structure division of disk loading device 10 of the present invention.Represent pallet 2 with double dot dash line, on this pan arrest 2, be integrally formed into tooth bar 7.On main truss 1, the power of accepting reversible CD-ROM drive motor 8 outputs can be installed freely to rotate and rotating gear 9a and the gear wheel in large diameter 9b that often meshes with this gear 9a, gear wheel in large diameter 9b goes up, be integral rotating small diameter gear 11 (below, it is called the 1st gear 11) coaxially with it is arranged on the position that is close with tooth bar.Gear 12 (below, it is called the 2nd gear) often meshing with the 1st gear 11, the 2nd gear 12 can revolve round the sun around gear 11.The 2nd gear 12 is on the support member 14 of freely rotating of center by 15 Zhi Zaineng of fulcrum with the fulcrum 13 of the 1st gear 11, revolution along with the 1st gear 11, by the rotation thrust that acts on the support member 14, and in a side of the 1st gear 11 or opposite side and 7 engagements of above-mentioned tooth bar.

In Fig. 2, the 1st gear 11 is along counter-clockwise direction revolution, and meanwhile the 2nd gear 12 carries out rotation along clockwise direction, by the turning power of gear 11 in the counter-clockwise direction thrust that revolved round the sun, meshing with tooth bar 7 therefrom.Like this, pallet 2 is moved along A direction (exit axis).

Have in the disk loading device of the present invention 10 of structure as mentioned above,, the fixed position place of the 1st gear 11 on main truss 1 turned round by the gear 9a, the 9b that constitute reduction gear by CD-ROM drive motor 8.And, be meshed with tooth bar 7 by the 2nd gear 12, make pallet 2 along in A direction (exit axis) moving process among Fig. 2, the external force that has the translational speed that makes pallet 2 to accelerate direction adds under thereon the occasion, then as Fig. 3 institute, the 2nd gear 12 is not subjected to tooth bar 7 pushings, support member 14 is revolved round the sun along clockwise.Therefore, the engagement of the 2nd gear 12 and tooth bar 7 is thrown off, can pallet 2 be subjected to the restriction of the speed of gyration of CD-ROM drive motor 8, lightly, withdraw from apace.At this moment, be not accompanied by the load that pallet 2 withdraws from owing to apply on each gear 9a, the 9b, 11,12, thereby can prevent the damage of tooth.

Like this, in disk loading device of the present invention, by the turning power of the 1st gear 11, make power that the 2nd gear 12 revolved round the sun and with tooth bar 7 engagements, by the rotation of the 2nd gear 12 pallet 2 is moved; Under the external force that has the translational speed of making to accelerate direction acts on occasion on the pallet 2, make the 2nd gear overcome the power of above-mentioned revolution and throw off with tooth bar 7.Become the gear that forms by the external force effect of special problem and the breakage of tooth bar before like this, just preventing really in the device.

Below, illustrate and make disk 2 with reference to Fig. 4 from withdrawing from the position to reproduction position, along the mobile occasion of B (reproduction position direction).When the gyratory directions of CD-ROM drive motor 8 being converted to Fig. 2 reverse direction, the just revolution along clockwise direction of the 1st gear 11.Therefore, make the revolution along clockwise direction around fulcrum 13 of the 2nd gear 12, with the opposition side of the 1st gear 11 engagements on again with tooth bar 7 engagements, along the counter-clockwise direction revolution, thereby pallet 2 is moved towards the B direction.If at this moment there is external force effect that the translational speed that makes pallet 2 accelerates direction thereon, then the 2nd gear is revolved round the sun by tooth bar 7 pushing ground, with similarly above-mentioned, has removed the engagement of itself and tooth bar 7.As a result, not moved lightly, apace by the pallet 2 that restrictedly makes of the speed of gyration of CD-ROM drive motor 8, and can prevent the breakage of gear and tooth bar.And, when above-mentioned external force to pallet 2 is eliminated, make the 2nd gear 12 and tooth bar 7 engagements again by the turning power of the 1st gear 11, automatically form from the power transfer path of CD-ROM drive motor 8 beginnings, pallet 2 is moved to the B direction with the speed of regulation.

Like this, no matter pallet 2 moves along A direction (exit axis) or B direction (reproduction position direction), by from outside, when adding towards the external force accelerating to move with methods such as manual operations, because the 2nd gear 12 and tooth bar 7 are broken away from, cut off from motor 8 to tooth bar 7 power transfer path, thereby can not damage gear series and tooth bar, can eliminate owing to accelerating pallet and move the fault of the disk loading device that causes and move bad.

What above-mentioned the 1st by way of example illustrated is the structure that makes the 2nd

single gear

12 and 11 engagements of the 1st gear, but, also can form the structure of variation shown in Fig. 5 (a) and (b) respectively, promptly with respect to the 1st gear 11, it medially is provided with a pair of the 2nd gear 12a, 12b, they and tooth bar 7 are meshed.

That is, as shown in Fig. 5 (a), support member 14 is stretched out for middle heart to the left and right with fulcrum 13, and fulcrum 15a, 15b are set, respectively at fulcrum upper support the 2nd gear 12a, 12b in the end that two stretches out.In Fig. 5 (a), when the 1st gear 11 turned round along the counter-clockwise direction shown in the arrow, the 2nd gear 12a of a side and tooth bar 7 engagements made tooth bar 7 move along A direction (exit axis), and the 2nd gear 12b of opposite side is in the position that breaks away from tooth bar 7.On the other hand, when clockwise direction is turned round, support member 14 is rotated at the 1st gear 11 along clockwise around fulcrum 13 by the turning power of the 1st gear 11, current, make the 2nd gear 12b and tooth bar 7 engagements of opposite side, thereby tooth bar 7 is moved to B direction (reproduction position direction).

Shown in Fig. 5 (b) is to make the structure of support member 11 in fulcrum 13 places bending.Thus, make in a pair of the 2nd gear, the disengaging configuration of the 2nd gear 12b of that side that breaks away from tooth bar 7 is in from the more approaching position of tooth bar 7.Like this, a pair of the 2nd gear 12a, 12b and tooth bar 7 combine and the action conversion of disengaging just can more promptly be carried out.

As above-mentioned variation, by a pair of the 2nd gear is set, because the moving direction according to tooth bar alternately meshes a pair of the 2nd gear with tooth bar, thereby, when the action of the moving direction of changing tooth bar, can reduce the amount of spin that support member 14 is reversed around fulcrum 13, in other words, can reduce the revolution amount of the 2nd gear, switching motion is more successfully carried out.And in this variation, tooth bar 7 is being added under the occasion of accelerating the external force on the moving direction, owing to the 2nd gear 12a or 12b and tooth bar 7 are broken away from the 1st embodiment, thereby can produce and the same effect of the 1st embodiment.Under this occasion, the 2nd gear is shown in Fig. 5 (b), owing to also often draw close tooth bar 7 after breaking away from tooth bar, the contacted state of the tooth top flank of tooth of maintenance and tooth bar 7 does not separate with tooth bar 7.Therefore, there is not such problem, i.e. the problem that is meshed with tooth bar of the 2nd gear 12b of the 2nd gear 12a of side opposite side when disengageably carrying out backward rotation with tooth bar 7.

Fig. 6～Figure 16 represents the 2nd embodiment of disk loading device of the present invention.Fig. 6 is the top hypertropia figure of the Disk regenerative device of the automatic transform of expression.Can free lifting on the main truss 21 of this regenerating unit support the secondary framework 22 that is provided with Disk regenerative portion, and lamination a plurality of pallets 23 are housed magazine 24 be provided in the front side of secondary framework 22.

Front opening part 24a by magazine 24 can insert pallet 23 or extract out with the relative magazine 24 of manual mode, on the shown position that withdraws from from front opening part 24a, replaces disk K on pallet 23.And the rear peristome 24b by magazine can be drawn out to pallet 23 on the secondary framework 22, just can carry out the regeneration of disk.That is to say, be to be contained in a plurality of pallets 23 multistage ground of placing disk K respectively in the magazine 24 by the Disk regenerative device shown in this 2nd embodiment.Can make the optional pallet 23 in position (below it being called stowed location) in this magazine 24, move to reproduction position and regenerate action again.And during the disk K in replacing magazine 24, can pallet 23 from the stowed locations in the magazine 24 outwards move to as shown in Figure 6 withdraw from position (below it being called disk replacement position).Make its with the corresponding occasion of the 1st embodiment under, this stowed location is equivalent to the position of withdrawing from the 1st embodiment.

Fig. 7 represents the oblique view of secondary framework 22 sides of regenerating unit, at the disk loading device of the present invention 26 that secondary framework 22 is being set on the main truss 21 and is making the elevating mechanism 25 of secondary framework 22 lifting moving and pallet 23 is moved back and forth between magazine 24 and secondary framework 22.On the secondary framework 22 rotating disk 22a and optical pick-up device 22b are being set, the elevating mechanism 25 of secondary framework 22 is propped up 3 cam shaft gears 27 (representing 1 cam shaft gear among the figure typically) on main truss 21, the synchronous rotating gear wheel in large diameter 28 of this cam shaft gear is constituted by axle.

Disk loading device 26 by the long cylinder gear 29 of the tooth width of cloth, often with the neutral gear 30 of these cylinder gear 29 engagements, coaxial and be integral the rotating small diameter gear 31 in ground (following it is called the 1st gear), the support member 32 that can freely rotate around the axle of the 1st gear 31, often mesh with the 1st gear 31 and can be supported in gear on the support member 32 (below it is called the 2nd gear) freely to rotate by fulcrum 32a and form with this neutral gear 30.That is, the structure of this 1st gear the 31, the 2nd gear 33 and support member 32 and the 1st gear the 11, the 2nd gear 12 and the support member 14 shown in the 1st embodiment are carried out same action accordingly.

As shown in Figure 8, above-mentioned elevating mechanism 25 and disk loading device 26 are by Action Selection mechanism 41, accept to carry out specified action from the turning power that is arranged on the reversible CD-ROM drive motor 40 on the main truss 21 selectively.Action Selection mechanism 41 is by the motor gear 42 on the revolving shaft 40a that is fixed on motor 40, often with the wobble gear 43 of motor gear 42 engagement, axle this wobble gear 43 and can be center and the rotor plate 44 that freely rotates with the revolving shaft 40a of motor 40, rotate (counter-clockwise direction among the figure) and make wobble gear 43 and axle to prop up the spring 45 of transmission gear 46 engagements on main truss 21 to a side on rotor plate 44 bullets, make rotor plate 44 overcome the power of spring 45 and actuating strut 47 that clockwise direction in the figure is rotated constitutes.Transmit gear 46 and often mesh with flange gear 29a, and flange gear 29a and cylinder gear 29 coaxial forming.

When the clockwise direction that makes rotor plate 44 by operational motion bar 47 in figure was rotated, wobble gear 43 meshed with the gear wheel in large diameter 28 of elevating mechanism 25, and the turning power bang path of motor 40 is transformed into elevating mechanism 25 sides from disk loading device 26 sides.Among the figure, be arranged on circular hole 22c on the secondary framework 22 and when secondary framework 22 lifting moving, be used for avoiding the escape hole of colliding with cylinder gear 29.

The neutral gear 30 of disk loading device 26 and the 1st gear 31 connect into coaxial one by revolution fulcrum 35.Revolution fulcrum 35 can freely move up and down the earth's axis and prop up on an end of secondary framework 22.And, the 1st gear 31 by the effect that is arranged on the compression spring 36 between secondary framework 22 and the support member 32 often by the top of bullet in Fig. 7.Therefore, when secondary framework 22 is risen, for example run into the barrier of not predicting and make under the occasion of being obstructed that rises,, the rising of secondary framework 22 can not hindered as long as by compression spring 36 is compressed at the 2nd gear 33.

On the other hand, by the 2nd gear 33 of running into barrier is revolved round the sun around the 1st gear 31, just it can be freed from the state of colliding, collide when being disengaged when this, the 1st gear 31 and the 2nd gear 33 are upwards shifted onto on the position of regulation with support member 32 by the restoring force of compression spring 36.

The 2nd ends member 65 admittedly under state shown in Figure 9, makes the pawl 65b and the 2nd that forms on the rotation front end end portion 62 admittedly and combines, and overcome the release power of releasing member 64 pallet 23 is remained in the magazine 24.

The 2nd ends member 65 admittedly is contained in the above-mentioned case 67.And can be installed with on case 67 with freely advancing and retreat releasing buckle 68.So, when local releasing button 68 is pressed into, push the 2nd by the stage portion 68a that removes button 68 and end member 65 admittedly and it is rotated to counter-clockwise direction, make pawl 65b and the 2nd end member 62 disengagements admittedly, thereby and make pallet 23 flown out outside the magazine 24 by above-mentioned extension spring 64c effect.The 2nd end portion 62 and the 2nd admittedly and end member 65 admittedly and remove button 68 and case 67 constitutes the pallet latch mechanism by this.

If above-mentioned case 67 is set the installation portion of usefulness is installed on the two sides of magazine 24, on the two sides of pallet 23, is provided with the 2nd and ends portion 62 admittedly, then can be installed in the pallet latch mechanism on any side of magazine, can make the outward appearance of device have diversity.

The 4th inclined-plane 23b that can slide and join with pawl 63b is being set in the 1st bight of ending portion's 61 sides admittedly of above-mentioned pallet 23.This 4th inclined-plane 23b is when being inserted into pallet 23 in the magazine outside

magazine

24, and 63b contacts with pawl, and makes the 1st to end the power that member 63 overcomes extension spring 66 admittedly and rotate to clockwise direction with the power of inserting pallet 23.

Below above-mentioned pallet 23, tooth bar 48 is installed, it be can along with the mobile phase of pallet with direction, move freely in specialized range with respect to this pallet 23.2 slotted

hole

48a and 48b are set on this tooth bar 48, on the lower surface of pallet, form and 2

chimeric guidance axis

23c, 23d of each slotted hole 48a, 48b.And, in a side slotted hole 48a, adorning the compression helical spring 70 shown in Figure 10,11 with inserting.Relative shifting range by the length restriction tooth bar 48 of the opposing party's slotted hole 48b.

The tooth 49 of tooth bar 48 and the 2nd gear 33 are vis-a-vis.As shown in figure 10, the front end in secondary framework 22 sides of tooth bar 48 is being provided with: at the outstanding uninterruptedly teat 48c of tooth bar side and the 1st gear 31, can move back dip plane 48e with contacted the 5th inclined-plane 48d of above-mentioned pawl 63b, the pressure that constitutes the 6th inclined-plane that can combine with the 2nd gear 33 in the side of pallet 23 side.The end of the 5th inclined-plane 48d arrives at the linearity part of pallet 23 sides.Above-mentioned teat 48c is combining pallet 23 and it and tooth bar 48 leave when magazine 24 withdraws from, with the 2nd gear 33.

Like this, when pallet 23 is withdrawed from, the 2nd gear 33 and tooth bar 48 are left, thereby can prevent being pressed into of when pallet 23 being inserted into once more 24 li of magazines the 2nd gear 33 obstruction pallets 23.

And, when pallet 23 being inserted into 24 li of magazines, even the 2nd gear 33 is under the occasion with tooth bar 48 positions of engagement, being pressed into, making to press and move back dip plane 48e and push the 2nd gear 33 by pallet, teat 48c push back the 2nd gear 33 not with the tooth bar motion track of tooth bar 48 engagement outside, the 2nd gear 33 is positioned at do not hinder on the position that pallet 23 is pressed into.

As shown in Figure 9, the 1st switch 71 and the 2nd switch 72 are being set on main truss 21.The 1st switch has and detects pallet 23 and be withdrawn into the function of the sensor of secondary framework 22 sides from magazine 24, and the 2nd switch has and detects the function that pallet 23 is withdrawn into the sensor on the secondary framework 22.These the 1st are being connected with CD-ROM drive motor 40 by control loop 73 as illustrated in fig. 9 with the 2nd switch 71,72.These

switches

71,72 are made of light-emitting component and photo detector, and the 1st switch 71 when pallet 23 being withdrawed from from magazine 24 and by pallet 23 light path is cut off, make control loop 73 actions with making 40 one-tenth driving conditions of above-mentioned CD-ROM drive motor during this period of time before pallet arrives secondary framework 22.

And the 2nd switch 72 is being withdrawn into pallet 23 on the secondary framework 22, and when by pallet 23 light path being cut off, makes control loop 73 actions, to stop the revolution of CD-ROM drive motor 40.

Be configured to the actuation time of these

switches

71,72 end the driving that

portion

61,62 stops motor 40 before combining admittedly at above-mentioned pawl 63b and the 1st or the 2nd.

The

switch

71,72 of the optical texture that forms by the combination of light-emitting component and photo detector shown in the also replaceable present embodiment, be provided with respectively on main truss 21 that the pallet withdrawed from by magazine 24 is pushed and rotating member and the pallet that arrived on the secondary framework 22 are pushed and the mechanical structures of rotating member the spring leaf switch that is switched on or switched off when turning round with these members.And can make above-mentioned control loop 73 actions by these spring leaf switches.

At the state of Fig. 9, be that pallet 23 is under the state of stowed location, when carrying out the regenerative operation of chosen disk K, make elevating mechanism 25 accept the power of motor 40 earlier and make the position of secondary framework 22 lifting moving to regulation.When detecting secondary framework 22 and reach the position of regulation, the power transfer path of motor 40 is transformed on the disk loading device 26 by above-mentioned Action Selection mechanism 41.At this moment, the clockwise direction revolution as shown in Figure 9 of the 1st gear 31, the 2nd gear 33 revolves round the sun around the 1st gear 31 along clockwise direction along counter-clockwise direction, rotation on one side, one side as illustrated in fig. 10, with tooth bar 48 and tooth bar 49 engagements.But, since at this moment the 1st pawl 63b that ends member 63 admittedly with the 1st admittedly only portion 61 combine, make with the 1st end admittedly member 63 the rotation direction almost parallel face 63c and with the 1st of pallet to end the face 61b of lateral vertical of portion 61 admittedly mutually opposed, thereby pallet 23 can not further move in the magazine 24.

But, because tooth bar 48 can move within the limits prescribed with respect to pallet 23, on one side thereby as shown in figure 11, have only tooth bar 48 compress above-mentioned compression spring 70, right-hand relatively mobile in figure.Push the 1st pawl 63b that ends member 63 admittedly to the 5th inclined-plane 48d of right-hand mobile tooth bar 48, this pawl 63d is ended member 61 admittedly from the 1st release, pallet 23 can be moved to right-hand.After this, the edge portion of guidance axis 23d and guide hole 48b joins and makes pallet 23 to the right-hand reproduction position that moves to.And, make 71 actions of the 1st switch along with this of pallet 23 moves, set motor 40 for driving condition by control loop 73.

To the right-hand pallet of sending to 23 as shown in figure 12, near portable terminal as reproduction position, the 1st pawl 63b that ends member 63 admittedly with the 2nd admittedly only portion 62 combine, pallet 23 is remained on the illustrated reproduction position.The 2nd switch 72 ends portion 62 admittedly at pawl 63b and the 2nd and moves before combine, and stops the revolution of motor 40 by control loop 73.At this moment and since pallet 23 as illustrated in fig. 13 the 3rd inclined-plane 63c of pawl 63b reach the 2nd end admittedly portion 62 in conjunction with the 62b of edge portion, and thereby pallet 23 the 1st end the rotating force of member 63 admittedly by what the elastic force of spring 66 formed to right-hand mobile.That is, being arranged on the 3rd inclined-plane 63c formation of ending admittedly on the member 63 as the 1st of solid locking mechanism works pallet 23 dipper crowding gear towards the portable terminal pushing after the driving that stops motor 40 with spring 66 1.At this moment, the 2nd gear 33 is pressed on the tooth 49 of the tooth bar 48 that links with pallet 23 to right-hand moving by pallet 23, thereby support member 32 is rotated along counter-clockwise direction.Owing to by this rotation the 2nd gear 33 is left as illustrated in fig. 14 with the tooth 49 of tooth bar 48, thereby has cut off the power that pallet 23 is moved.Because the 2nd gear 33 breaks away from the tooth 49 of tooth bar 48, thereby the 2nd gear 33 does not hinder pallet 23 to right-hand moving.In addition, end portion 62 admittedly in conjunction with being ended on reproduction position to the right-hand pallet of sending to 23 by the 1st the 3rd inclined-plane 63c and the 2nd that ends member 63 admittedly by solid.Like this, pallet 23 drives reaching near removed motor 40 portable terminal of reproduction position pressure, after this, and be to move by the 1st rotating force of ending member 63 admittedly as described above, thereby can eliminate the location instability of the reproduction position that forms by the inertia of motor up to reproduction position.

Like this, owing to arrive the portable terminal of reproduction position at pallet 23 near motor 40 is stopped, and carry out moving of the pallet that causes by the 2nd gear 33, thereby do not add all that on all gears the revolution that brings along with stopping of moving of pallet loads.And by the tooth 49 of cut-out tooth bar 48 and the engagement of the 2nd gear 33, the 2nd gear 33 just can not hinder by the 1st and end pallet 23 the moving up to portable terminal that member 63 forms admittedly.Again because push back the glide plane 23f that forms on member 64 and pallet 23 sides ground connection gap up and down of limiting pallet mutually, so can carry out the location of pallet more accurately.

In order to revert to stowed location to the right-hand pallet 23 that moves to reproduction position, the operation that advanced regeneration of exercising disk K stops.Immediately, make motor 40 carry out reversed turning, the 1st gear 31 is turned round along the counter-clockwise direction among Figure 14 by this operation.Make the rotation on one side along clockwise direction of the 2nd gear 33 by counterclockwise revolution of this 1st gear 31, around the 1st gear 31, revolve round the sun on one side, with tooth 49 engagements of tooth bar 48 along counter-clockwise direction.Even begin to move with pallet 23 left in figure, move by this, make the 2nd to end the 3rd inclined-plane 63c that ends the 62b of edge portion pushing pawl 63b admittedly of portion 62 admittedly, make the 1st to end member 63 admittedly and rotates along clockwise direction, pawl 63b is ended portion's release admittedly from the 2nd.Then, in front of pallet 23 reached the stowed location that pawl 63b and the 1st ends Fig. 9 that portion 61 combines admittedly, the 1st switch 71 stopped the revolution of motor 40.At this moment, pallet 23 is subjected to (formation makes dipper crowding gear that pallet 23 is moved further) release member 64 and carries out mobilely a little again, is moved by this and the 2nd gear 33 to be pressed on the tooth 49 of tooth bar 48 and to remove engagement with tooth bar.The pallet of sending to left 23 ends member 63 and the 1st admittedly by the 1st and ends portion 61 admittedly and release that member 64 is solid to be ended and remain on the stowed location.

Like this; make pallet 23 from reproduction position when stowed location moves; arrive the mobile terminal locations place of stowed location at pallet 23; when ending admittedly by solid locking mechanism; also be at dump to the front with motor 40; after; up to stowed location; owing to delivering to mobile terminal locations (stowed location) by the pushing effect that is arranged on the dipper crowding gear on the solid locking mechanism; the 2nd gear 33 be subjected to tooth bar 48 tooth 49 pushing and throw off with tooth bar 48; do not hinder the mobile of the pallet that forms by solid locking mechanism; even thereby it is stopped; also load is not added on the gear, can protect gear.And the inertia of motor 40 can not play bad influence to the location of pallet 23 yet.

Figure 16 be illustrated in a pallet 23 from magazine 24 outwards towards disk replace the position, when left withdraws from, the teat 48c of tooth bar 48 makes state that the 2nd gear 33 and tooth bar 48 break away from, when remaining on pallet 23 in the magazine 24, the state that the 2nd gear 33 meshes along the counter-clockwise direction revolution and with the tooth 49 of formation and tooth bar 48 around the 1st gear 31 as illustrated in fig. 15.

When from this state pallet 23 when left withdraws from, the 2nd gear 33 is subjected to teat 48c pushing and breaks away from the tooth 49 of tooth bar 48, and stay on the position of this disengagement, pallet 23 is moved to the foreign side of magazine 24, just can with tooth bar 48 from the engagement of the 2nd gear 33 throw off.Therefore, pallet 23 is being replaced that the position is inserted into magazine 24 in once more and to right-hand when mobile from magazine,, thereby can not hinder the mobile of pallet 23 with because the 2nd gear 33 do not mesh with tooth bar 48.

Because when pallet 23 being pushed into 24 li of magazines, the 6th inclined-plane 48e that forms at the front end of tooth bar 48 and teat 48c boost, make it to be in not and tooth bar 48 position engaged the 2nd gear 33, thereby the 2nd gear 33 can not hinder pallet 23 and passes in and out to magazine 24.In addition, when pallet 23 is withdrawed from, can with certain reason make the 2nd gear move to tooth bar 48 position engaged on, thereby if adopt by be arranged on the bar 37 on the support member 32 and be formed on the secondary framework 22 limit rotation sheet 38 with the 2nd gear 33 stay can with the structure in the scope of tooth bar 48 engagements, just can more positively pallet 23 be inserted in the magazine 24.

Structure as dipper crowding gear, can omit release member 64 and with its replace to the 1st admittedly only the fore-end of the pawl of member 63 make the triangular shape projection, the the 1st and the 2nd shape of ending

portion

61,62 is admittedly also made the solid locking mechanism of triangular shape, near the portable terminal of pallet, engagement by the recess of the projection of triangular shape and triangular shape makes pallet move to moving direction by spring force.Under this occasion, also can with the 1st end member 63 admittedly and be provided with respectively and make pallet be sent to the member of secondary framework 22 sides meticulously.In addition, the present invention is not limited to the 1st and the 2nd above-mentioned embodiment and variation.In the above-described embodiment, CD-ROM drive motor is illustrating with reversible rotary type, even but motor is unidirectional rotary type, if general revolution throw-over gear is set in gear series, the 1st gear is turned round selectively along both direction, can obtain same effect, this structure is also contained among the present invention.
