And centering adjustment component 14a and 14b are configured in the rear side of the CD placed side 3a of protecgulum 3 as illustrated in fig. 4.Therefore, with Fig. 3 in the centering adjustment component 14a and the gear 8f of the aligning parts 8a of the gearing mesh of 14b and the 8b back side that is configured to arrive protecgulum 3.And, centering adjustment component 14a and 14b go up the pitch diameter (PCD:Pitch Circle Diameter) of the gear that is provided with and set greatlyyer than the pitch diameter of gear 8f, thus, when rotating centering adjustment component 14a and 14b, the amount of spin of adjustment component 14a and 14b was big during the amount of spin of aligning parts 8a~8d can be compared.In the present embodiment, owing to the pitch diameter of centering adjustment component 14a and 14b is set at about 2 times of pitch diameter of gear 8f, therefore the rotational angle (amount of spin) of centering adjustment component 14a and 14b is half of rotational angle (amount of spin) of aligning parts 8a~8d, and tooth bar 16 and 17 amount of movement also become half.
The 1st tooth bar 16 and the 2nd tooth bar 17 are configured to, and can be the center with the line at the center of center by rotating disk 1 and light picker 2, move to approximate vertical direction and opposed direction with identical speed.The 1st tooth bar 16 is positioned at aligning parts 8c side as shown in Figure 3 when but optical disc apparatus is in the fixing disc state, its left part 16a and centering adjustment component 14a butt, and restriction centering adjustment component 14a is to the rotation of arrow A direction.And, but the 2nd tooth bar 17 is positioned at aligning parts 8d side as shown in Figure 3 when optical disc apparatus is in the fixing disc state, its right part 17a and centering adjustment component 14b butt, and restriction centering adjustment component 14b is to the rotation of arrow A direction.And the 1st tooth bar 16 can move to the arrow E direction by the drive source drives power such as motor from other setting, and the 2nd tooth bar 17 can move to the arrow B direction.In addition, the driving mechanism of relevant the 1st tooth bar 16 and the 2nd tooth bar 17 will be narrated in the back.
In addition, regularly identical by the mobile beginning that makes the 1st tooth bar 16 and the 2nd tooth bar 17, can improve the accuracy of alignment of CD 4.Moreover to move beginning regularly identical by making, and translational speed equates, can further improve accuracy of alignment.
In addition, though adopt the structure that is delivered to tooth bar 16 and 17 from drive source drives power respectively independently, but in the present embodiment, form tooth 16c and 17c by opposed position in tooth bar 16 and 17, be provided with and two tooth 16c and 17c meshed gears 31, in the future the driving force in self-driven source passes to gear 31, driving force can be passed to tooth 16c and 17c with gear 31 engagements, and can make tooth bar 16 and 17 is that the direction of arrow B and E moves to opposed direction respectively.
And, rotating in identical timing in order to make aligning parts 8a and 8c and aligning parts 8b and 8d, tooth bar 16 and 17 adopts the structure with the identical as far as possible part butt of centering adjustment component 14a and 14b.
And tooth bar 16 and 17 configuration when optical disc apparatus is seen in the front as shown in Figure 3 is mutual discontiguous configuration, and the configuration when seeing from the side as shown in Figure 4 is the configuration of vertically arranging.
Though not expression among 17 the maintenance figure of relevant tooth bar 16 for example can be considered along the length direction of each tooth bar 16 and 17 cam path to be set, at the pin that device one side setting engages with cam path, the structure of free sliding ground maintenance tooth bar and other structure.
The following describes the action of the optical disc apparatus of said structure.
(the loading and unloading action of major diameter CD)
Among Fig. 3, under the user was placed into CD 4 state on CD placed side 3a and the flange 3c, CD 4 was positioned at its center than the position of side on the lower side, the center of rotating disk 1.And the position of the left and right directions of CD 4 is contacted with aligning parts 8a~8d by CD 4 simultaneously by the 3e of wall portion restriction, plays the effect of position limit to a certain degree.At this moment, aligning parts 8a~8d keeps out of the way, and is not positioned on the projecting plane of CD placed side 3a.And centering adjustment component 14a and 14b are positioned at position shown in Figure 3.And the left part 16a of the 1st tooth bar 16 and centering adjustment component 14a connect, and the right part 17a of the 2nd tooth bar 17 and centering adjustment component 14b connect, and restriction centering adjustment component 14a and 14b and aligning parts 8a~8d are to the rotation of arrow A direction.
Then, if the switch (not shown) of beginning is reproduced in operation note, clamper base 10 begins to move to arrow B direction (direction vertical with the moving direction of light picker 2) from holding fix shown in Figure 3, moves to clip position shown in Figure 5.
Then, as shown in Figure 4, the rotary driving force of motor 33 outputs is delivered to gear 31 by motor gear 34, is delivered to the 1st tooth bar 16 and the 2nd tooth bar 17 with gear 31 engagements again.The 1st tooth bar 16 begins to move from position shown in Figure 3 direction to arrow E, and the 2nd tooth bar 17 begins to move to the arrow B direction from position shown in Figure 3.So, centering adjustment component 14a and 14b connect with tooth bar 16 and 17 under the elastic force effect of spring 13a and 13b, rotate to the arrow A direction in this state.Following in this, with the aligning parts 8a and the 8b of centering adjustment component 14a and 14b engagement, is that axial arrow A direction is rotated with fulcrum 8e, and the aligning parts 8c and the 8d that mesh with aligning parts 8a and 8b are axle with fulcrum 8e, rotate to the arrow A direction.
And the 2nd tooth bar 17 moves to the direction shown in the arrow B, makes the pin 17d that is fixed on the 2nd tooth bar 17 to arrow B direction pushing lever 32, and lever 32 serves as axially counterclockwise to rotate with fulcrum 32c.Lever 32 is connected and opens and closes on the parts 9, and the rotation of lever 32 makes switching parts 9 move to direction shown in the arrow B.In addition, about lever 32 and the relation that opens and closes parts 9, and the detailed shift action of switching parts 9 will be narrated in the back.
Aligning parts 8a~the 8d that follows moving of the 1st tooth bar 16 and the 2nd tooth bar 17 and rotate, soon with the peripheral part butt of CD 4, if further rotate, then can be as illustrated in fig. 5, the edge part of CD 4 slides at the CD abutting part of aligning parts 8a~8d, and CD 4 is moved to the center position of rotating disk 1.
In the present embodiment, when aligning parts 8a~8d rotates, the aligning parts 8c of downside and the peripheral part of 8d and CD 4 are connected, be rotated further action in this state, can lift CD 4 to the center position of rotating disk 1.Then, the aligning parts 8a of upside and the periphery of 8b and CD 4 are connected, like this can be at the edge of 4 position supporting CDs 4.
As shown in Figure 5, when arriving centering end positions (the 3rd position) as if CD 4, the 1st~the 4th aligning parts 8a~8d stops at elastic force pushing that utilizes spring 13a and 13b and the state that keeps the edge of CD 4.At this moment, force balance, aligning parts 8a~8d stops at the state at the edge of pushing and supporting CD.And the switching parts 9 that move though follow moving of the 2nd tooth bar 17 in Fig. 5 move to the position that the part of peristome 3b is opened, and are moved further by making tooth bar 16 and 17, move to the position of opening peristome 3b fully.
In addition, even aligning parts 8a~8d is supported by the edge part of CD 4, tooth bar 16 and 17 also continues the shift action to arrow B and E direction.Because the edge part butt of aligning parts 8a and 8c and CD 4, so the rotation of aligning parts 8a and 8c is limited, and the rotation of centering adjustment component 14a is limited.Therefore, tooth bar 16 continues to move to the arrow E direction, and centering adjustment component 14a is separated with tooth bar 16.And because the edge part butt of aligning parts 8b and 8d and CD 4, so the rotation of aligning parts 8b and 8d is limited, and the rotation of centering adjustment component 14b is limited.Therefore, tooth bar 17 continues to move to the arrow B direction, and centering adjustment component 14b is separated with tooth bar 17.
Then, the base 5 that traverses is that middle mind-set arrow C direction shown in Figure 4 is rotated with fulcrum 5a, and rotating disk 1 passes peristome 3b and moves to the record-playback position.In addition, will narrate in the back about the detailed rotational action of the base 5 that traverses.
Thus, CD 4 is placed on the CD placed side of rotating disk 1 and is lifted.When rotating disk 1 moved near the clip position of CD 4, clamper 11 was pulled to the CD placed side of rotating disk 1 under the effect of magnetic force, and CD 4 is by rotating disk 1 and clamper 11 clampings.In addition, this hour rack 16 and 17 is proceeded the shift action to the direction of arrow B and E.
If continue to move at chucking optical disk 4 back the 1st tooth bars 16 and the 2nd tooth bar 17, the right part 16b of the 1st tooth bar 16 and centering adjustment component 14b connect soon, and the left part 17b of the 2nd tooth bar 17 and centering adjustment component 14a connect.
Further, if the 1st tooth bar 16 moves to the arrow E direction, the 2nd tooth bar 17 moves to the arrow B direction, then the 1st tooth bar 16 pushes centering adjustment component 14b, make centering adjustment component 14b begin to rotate to arrow D direction, and the 2nd tooth bar 17 pushing centering adjustment component 14a make centering adjustment component 14a begin to rotate to arrow D direction.
Follow in this, the rotating force of centering adjustment component 14a is passed to aligning parts 8a and 8c by gear, and the rotating force of centering adjustment component 14b is passed to aligning parts 8b and 8d by gear.Thus, as shown in Figure 6, aligning parts 8a~8d rotates to arrow D direction respectively, keeps out of the way the position of leaving CD 4 peripheries.At this moment, CD 4 is held device 11 and rotating disk 1 clamping as shown in Figure 7.
Then, rotating disk 1 rotates and makes CD 4 rotations, and light picker 2 can carry out the record or the reproduction of information signal to CD 4.
In addition, the 1st~the 4th aligning parts 8a~8d leaves the retreating position behind the CD 4, so long as leave the periphery of the CD 4 that is placed on the rotating disk 1, can keep out of the way the arbitrary position between the 2nd position and the 3rd position.
In addition, though being shift action, the centering action according to clamper base 10, the such order of mobile (clamping) action of traversing, above-mentioned CD installation action carries out, but might not leave no choice but can not by such order, so long as can enter into the state of chucking optical disk 4, also it doesn't matter for the change order.
The following describes the action when from optical disc apparatus, taking out CD 4.
As shown in Figure 6, take out the switch (not shown) that CD is used if be positioned under the state of record-playback position operation at CD 4, then the rotation of rotating disk 1 stops, and the rotation of CD 4 stops.Then, the driving force from motor 33 (with reference to Fig. 4) output is delivered to tooth bar 16 and 17.
Then, the 1st tooth bar 16 begins to move to the arrow B direction from position shown in Figure 6.And the 2nd tooth bar 17 begins to move to the arrow E direction from position shown in Figure 6.Follow in this, the application of force of spring 13a and 13b make centering adjustment component 14a with the state of tooth bar 17 butts under rotate to the arrow A direction, centering adjustment component 14b with the state of tooth bar 16 butts under rotate to the arrow A direction.Moreover, by the aligning parts 8a~8d of gear, be that axial arrow A direction is rotated with fulcrum 8e with centering adjustment component 14a and 14b engagement.
Then, as shown in Figure 5, aligning parts 8a~8d (leaves the position of CD 4) from the 2nd position and turns to the 3rd position of the edge part of supporting CD 4, utilizes the application of force pushing of spring 13a and 13b and the edge part of supporting CD 4.In addition, even the edge part of aligning parts 8a~8d supporting CD 4, tooth bar 16 and 17 is also proceeded the shift action to arrow B and E direction.And if tooth bar 16 and 17 moves to assigned position, the right part 16b of the 1st tooth bar 16 separates with centering adjustment component 14b, and the left part 17b of the 2nd tooth bar 17 separates with centering adjustment component 14a.
Then, the base 5 that traverses is that middle mind-set arrow F direction is rotated with fulcrum 5a as illustrated in fig. 7, but moves to waiting status shown in Figure 4 from the record-playback state.Follow in this, rotating disk 1 overcomes magnetic attracting force with clamper 11 and separates, and the CD 4 that is held is in the state that is only supported by aligning parts 8a~8d as shown in Figure 5.
If the 1st tooth bar 16 moves to the arrow B direction, the 2nd tooth bar 17 moves to the arrow E direction, then as shown in Figure 3, and the left part 16a of the 1st tooth bar 16 and centering adjustment component 14a butt, the right part 17a of the 2nd tooth bar 17 and centering adjustment component 14b butt.Behind butt, if the 1st tooth bar 16 moves to the arrow B direction, then the centering adjustment component 14a that is pushed by the 1st tooth bar 16 overcomes the application of force of spring 13a and rotates.With the application of force that the aligning parts 8a and the 8c of centering adjustment component 14a engagement overcomes spring 13a and 13b respectively, rotate to arrow D direction.Follow in this, CD 4 is placed on the flange 3c in the CD bearing surface slide down of aligning parts 8c and 8d.Then, when the 1st tooth bar 16 and the 2nd tooth bar 17 arrived the 1st position shown in Figure 3, motor 33 stopped, and the rotation of motor gear 34 and gear 31 stops, and the 1st tooth bar 16 and the 2nd the mobile of tooth bar 17 stop.
Then, clamper base 10 moves from clip position shown in Figure 5 direction to arrow E by driving mechanisms such as motor, waits at holding fix shown in Figure 3.Thus, be in the state that the user can take out CD 4 from optical disc apparatus.
Here, open and close parts 9 along with tooth bar 17 to the moving of arrow E direction, move to the position of covering peristome 3b shown in Figure 3.
In addition, carry out according to the order that clamping is removed, centering is removed, the clamper base is kept out of the way though above-mentioned CD takes out action, might not leave no choice but by this order can not, as long as can change to desirable doing well from clamp position, order changes and also has no relations.
(the loading and unloading action of minor diameter CD 18)
The optical disc apparatus of present embodiment can also load and unload minor diameter CD 18 as shown in Figure 8.Fig. 8 is the vertical view that minor diameter CD 18 (for example diameter 8 centimetres CD) state has been installed in expression.
The installation action of the installation action of minor diameter CD 18 and above-mentioned major diameter CD 4 is roughly the same, but centering adjustment component 14a is different with the amount of spin of 14b and aligning parts 8a~8d.That is,, during therefore with minor diameter CD 18 centerings, need make aligning parts 8a~8d and centering adjustment component 14a and 14b rotate bigger amount because the diameter of minor diameter CD 18 is littler than the diameter of major diameter CD 4.
In order to increase the amount of spin of each parts, not only to increase formation scope, and need make configuration or the elasticity coefficient optimization of spring 13a and 13b at the gear 8f that forms on aligning parts 8a~8d, the gear that on centering adjustment component 14a and 14b, forms.And, be necessary to make the length of aligning parts 8a~8d or configuration to be suitable for keeping being placed on minor diameter CD 18 on the flange 3c most.

In addition, because the action of the centering of minor diameter CD 18 is identical with the centering action of above-mentioned major diameter CD 4, therefore omit detailed action specification.
(the loading and unloading action of tray salver 19)
Below, the loading and unloading action of tray salver 19 is described with reference to Fig. 9 and Figure 10.
Fig. 9 is the vertical view that the state of the CD (hereinafter referred to as " tray salver ") that is housed in the housing has been installed in optical disc apparatus.Figure 10 is the sectional view when tray salver has been installed in optical disc apparatus, is the cut-open view at the X-X position of Fig. 9.
As shown in Figure 9, be positioned under the state of the 1st position at the 1st~the 4th aligning parts 8a~8d, the user can be placed on tray salver 19 on CD placed side 3a and the flange 3c.Under the user is placed into tray salver 19 state on CD placed side 3a and the flange 3c,, realize the position limit of left and right directions by being positioned at aligning parts 8a~8d that overlooking of CD placed side 3a held about direction.
At this moment, the 1st does not contact with the left part 9a of tray salver 19 with 8c with the 3rd aligning parts 8a, is in the state of separation.And the 2nd does not contact with the right part 9c of tray salver 19 with 8d with the 4th aligning parts 8b, is in the state of separation.And centering adjustment component 14a and 14b are positioned at position shown in Figure 9.
And the left part 16a of the 1st tooth bar 16 and centering adjustment component 14a connect.And the right part 17a of the 2nd tooth bar 17 and centering adjustment component 14b connect.Therefore, centering adjustment component 14a and 14b and aligning parts 8a~8d are limited to the rotation of arrow A direction.
Then, if the switch (not shown) of beginning is reproduced in operation note, clamper base 10 moves to arrow B direction (direction vertical with the moving direction of light picker 2) from holding fix shown in Figure 9 by driving mechanisms such as motor.Clamper base 10 moves to the center and the roughly consistent clip position (not shown) in the center of clamper 11 of rotating disk 1.
Then, the rotary driving force from motor 33 (with reference to Fig. 4) output passes to tooth bar 16 and 17 by motor gear 34 and gear 31.Tooth bar 16 begins to move to the arrow E direction from position shown in Figure 9 under the effect of transmitting the driving force of coming, and tooth bar 17 begins to move to the arrow B direction from position shown in Figure 9 under the effect of transmitting the driving force of coming.
When the mobile beginning of tooth bar 16 and 17, under centering adjustment component 14a and the 14b application of force and the state of tooth bar 16 and 17 butts by spring 13a and 13b, rotate to the arrow A direction.When centering adjustment component 14a and 14b rotation,, be that axial arrow A direction is rotated with fulcrum 8e with the aligning parts 8a~8d of centering adjustment component 14a and 14b engagement.
Aligning parts 8a~the 8d that is rotating and the left part 9a of tray salver 19 and right part 9c butt stop under the state of the left part 9a of the pushing of the application of force by spring 13a and 13b tray salver 19 and right part 9c.Thus, finish the location of the left and right directions of tray salver 19.In addition, tray salver 19 is positioned on above-below direction under the state that is placed on the flange 3c.
Even the left part 9a of aligning parts 8a~8d and tray salver 19 and right part 9c butt, tooth bar 16 and 17 is also proceeded the shift action to arrow B and E direction.If tooth bar 16 and 17 continues to move, the left part 16a of the 1st tooth bar 16 separates with centering adjustment component 14a, and the right part 17a of the 2nd tooth bar 17 separates with centering adjustment component 14b.
Then, be located at the shutter 19b on the tray salver 19, be opened by shutter switching mechanism (not shown).
Then, the base 5 mind-set arrow C direction from holding fix shown in Figure 10 with fulcrum 5a is of traversing is rotated.When the base 5 that traverses rotated, rotating disk 1 passed peristome 3b and moves to the record-playback position.Thus, the CDs 4 in the tray salver 19 are placed on the CD placed side of rotating disk 1 and are lifted.
If CD 4 is lifted by rotating disk 1, then be positioned at the CD placed side that under magneticaction, is pulled to rotating disk 1 with rotating disk 1 opposed locational clamper 11, CD 4 is by rotating disk 1 and clamper 11 clampings.In addition, during holding action, tooth bar 16 and 17 shift actions that continue to arrow B direction and E direction.
Then, traversing base 5 after the mobile end of record-playback position, the right part 16b of the 1st tooth bar 16 and centering adjustment component 14b butt, the left part 17b of the 2nd tooth bar 17 and centering adjustment component 14a butt.
Moreover, if the 1st tooth bar 16 continues to move to the arrow E direction, the 2nd tooth bar 17 continues to move to the arrow B direction, then the 1st tooth bar 16 pushing centering adjustment component 14b make centering adjustment component 14b rotate to arrow D direction, and the 2nd tooth bar 17 pushing centering adjustment component 14a make centering adjustment component 14a rotate to arrow D direction.
If centering adjustment component 14a and 14b rotate, the rotating force of centering adjustment component 14a is given aligning parts 8b and 8d by gear transmission, and the rotating force of centering adjustment component 14b is given aligning parts 8b and 8d by gear transmission.Thus, aligning parts 8a~8d rotates to arrow D direction, leaves the left part 9a and the right part 9c of tray salver 19.
Then, rotate rotating disk 1 and make CD 4 rotations, 2 pairs of CDs of light picker 4 carry out the record or the reproduction of information signal.
Below, the situation when taking out tray salver 19 from optical disc apparatus is described.
CD 4 in tray salver 19 is positioned under the state of record-playback position, if the operation CD takes out with switch (not shown), the rotation of rotating disk 1 stops, and the rotation of CD 4 stops.
Then, the driving force from motor 33 (with reference to Fig. 4) output passes to tooth bar 16 and 17 by motor gear 34 and gear 31.The driving force of being transmitted makes the 1st tooth bar 16 begin to move to the arrow B direction from the state with centering adjustment component 14b butt, makes the 2nd tooth bar 17 begin to move to the direction of arrow E from the state with centering adjustment component 14a butt.
When the 1st tooth bar 16 and the 2nd tooth bar 17 moved, centering adjustment component 14a and 14b connected by the application of force and the tooth bar 16 and 17 of spring 13a and 13b, rotate to the arrow A direction under this state.Following in this, by the aligning parts 8a~8d of gear with centering adjustment component 14a and 14b engaging, is the direction rotation of axial arrow A with fulcrum 8e.
Then, aligning parts 8a~8d (leaves the position of tray salver 19) from the 2nd position and turns to the 3rd position of the side of supporting tray salver 19, utilizes the application of force pushing of spring 13a and 13b and the left part 9a and the right part 9c of supporting tray salver 19.
In addition, even the left part 9a of aligning parts 8a~8d and tray salver 19 and right part 9b butt, tooth bar 16 and 17 is proceeded the shift action to arrow B and E direction.If tooth bar 16 and 17 continues to move, the right part 16b of the 1st tooth bar 16 separates with centering adjustment component 14b, and the left part 17b of the 2nd tooth bar 17 separates with centering adjustment component 14a.
Then, the base 5 that traverses is the counter-rotation of middle mind-set arrow C with fulcrum 5a, moves to holding fix shown in Figure 10.Follow in this, leave the CD placed side of rotating disk 1 by the CD 4 of rotating disk 1 and clamper 11 maintenances.In addition, this hour rack 16 and 17 is proceeded moving to arrow B and arrow E direction respectively.
