As shown in Figure 7, under the state that positioning sliding block 61 is locked by the first lock portion 61f, be located at the register pin 62a on the positioning sliding block 61,62b is near the center (being the driving center of disk) of panoramic table T and binding clasp 16.As shown in figure 14, be in the register pin 62a of waiting status, 62b can be positioned at minor diameter disk DS on the position at above-mentioned driving center.
(the importing action of major diameter disk DL)
Shown in Fig. 2 (A), as 2 insertion mouth 2a from the head, when major diameter disk DL being inserted among the opening 1a of framework 1, insert the test pin 8 and 9 of the both sides among the A of testing agency, be open towards X1 direction and X2 direction.In Fig. 2 (A), detection arm 6 and 7 is rotated, and detector switch SW1 and SW2 disconnect.Again, in Fig. 2 (B), sub-arm 13 switches to off-state with detector switch SW3, after, become on-state again.Utilize the switching output of this detector switch, can detect the insertion situation of major diameter disk DL.
When above-mentioned detector switch S1 or SW2 disconnection, by the control loop that does not illustrate among the figure, send the order that motor begins to move, motor begins starting.Utilize this motor can drive the gear wheel in large diameter 33 of the B of powershift mechanism, rotate to clockwise direction.Under waiting status, shown in Fig. 4 (A), owing to make the follower gear 45 and gear wheel in large diameter 33 engagements that are integral with roller 5, when motor began to rotate, power passed to follower gear 45 by gear wheel in large diameter 33, and roller 5 beginnings are to counterclockwise rotating.Therefore, major diameter disk DL is clamped by roller 5 and roller flange 44, utilizes the rotating force of roller 5, sends into to the inside of framework 1 (Y1 direction).
Under state shown in Fig. 4 (A), because driven wheel 32 with gear wheel in large diameter 33, rotates towards clockwise direction, the idling gear 35 that meshes with driven wheel 32 rotates to counter clockwise direction.At this moment, to clockwise rotating force, pass through friction force, act on the lever arm 74, as Fig. 6 (A) amplifies expression, because the front end 34a of lever arm 34 contact with the 3rd cam 21d of change gear 21, but restraint arm 34 to clockwise rotation, idling gear 35 and change gear 21 disengagings.Therefore, as the major diameter disk DL that utilizes roller 5 and roller flange 44 to clamp, when the Y1 direction was carried, change gear 21 stopped, and first switches lever 22 and second switches the state that lever 23 is in Fig. 4 (A).
Fig. 8 represents, at major diameter disk DL, in the way that the Y1 direction is carried, when major diameter disk DL towards the Y1 direction carry given apart from the time, the circumferential edges of the front end of the direction of insertion of major diameter disk DL and register pin 62a, 62b contacts.At this moment, the B of powershift mechanism is in the state of Fig. 4 (A).
In addition, from inserting major diameter disk DL, to the time that moves to position shown in Figure 8, owing to insert the test pin 8 of the A of testing agency, pressed mobilely by the circumferential edges of major diameter disk DL, therefore, the locking actuating arm 66 that is connected with test pin 8 rotates to clockwise direction.Therefore, be located at the drive pin 67 on the locking actuating arm 66, compress the drive hole 63b that locks lever 63 towards the X2 direction, locking lever 63 towards X2 directions are moved, locking pin 65 leaves the first lock portion 61f, and the locking of positioning sliding block 61 is disengaged.
Therefore, as major diameter disk DL, from the state of Fig. 8, when the Y1 direction was carried, the inserting side front end of major diameter disk DL compressed register pin 62a, and 62b moves positioning sliding block 61 towards Y1 directions.When positioning sliding block 61 towards Y1 directions move, be located at the drive pin 61d on this positioning sliding block 61, compress detection and localization arm 56 along the Y1 direction.At this moment, drive pin 61d slides in the detection drive hole 56b of detection and localization arm 56, and detection and localization arm 56 is a fulcrum with the connecting pin 57 that is connected with trigger arm 54, to (the 1. direction of Fig. 8) rotation counterclockwise.At this moment, make the circular hole 56a on detection and localization arm 56, on axle 4c set on the top board 4, slide.
Fig. 9 represents that the center of major diameter disk DL arrives the state at the center of the panoramic table T of disk drive U and binding clasp 16.
Before arriving Fig. 9 state, because the clockwise end as the circular hole 56a of second coupling part of detection and localization arm 56 contacts with a 4c, DL is pressed to the Y1 direction with positioning sliding block 61 when the major diameter disk, when drive pin 61d slides in detecting drive hole 56b, towards the rotating force that with axle 4c is the counter clockwise direction (the 2. direction of Fig. 9) of fulcrum, act on the detection and localization arm 56, detection and localization arm 56 rotates to second detection position.This rotating force makes trigger arm 54 rotate to clockwise direction (3. direction), the pin 55 that is located on the trigger arm 54 is pressed to the Y1 direction with the trigger recess 25c of trigger lever 25, as Fig. 9 4. shown in, trigger lever 25 moves the distance of a weak point to the Y1 direction.
When trigger lever 25 during to short distance of 4. direction motion, tooth bar 25d makes control solid of revolution 75, to the little rotation of clockwise direction pin a bit.Simultaneously, under the state of Fig. 9, control solid of revolution 75 also turns round a bit a little, makes the locking control cam 75a on control solid of revolution 75, and the left end 63c from locking lever 63 leaves a bit a little.On the one hand, DL is delivered to position shown in Figure 9 when the major diameter disk, when the center of major diameter disk DL arrives the driving center, because the rear portion circumferential edges of major diameter disk DL leaves test pin 8, then spring 11 makes detection arm 6 reset to counter clockwise direction, and locking actuating arm 66 also resets to counter clockwise direction.Therefore, locking lever 63 is in free state, is promoted by locking spring 64, moves to the X1 direction, and locking pin 65 engages with the second lock portion 61g of positioning sliding block 61, and positioning sliding block 61 does not return to Y2 direction (holding fix direction), and locks.
In addition, send to the edge of the Y1 direction of the major diameter disk DL of the centre of gyration consistent location of center and panoramic table T, with another keeper 15c that is located on the clamp arm 15, the 15d contact, major diameter disk DL stops on this position.Therefore, leave major diameter disk DL to decline during this period of time at roller 5, major diameter disk DL does not move to the Y1 direction, and is positioned.
As shown in Figure 9, arrive the driving center at the center of major diameter disk DL, by keeper 15c, under the state of 15d location, because actuating arm 68 leaves the driving cam 75b of control solid of revolution 75, actuating arm 68 is in free state, and returning spring 72 can provide to clockwise rotating force.Therefore, the restoring force to the Y2 direction acts on the positioning sliding block 61 that is connected with actuating arm 68.Like this, clamp major diameter disk DL at roller 5 and roller flange 44, the moment of carrying capacity effect is arranged, major diameter disk DL does not return to the Y2 direction.Behind the state that reaches Fig. 9, when roller 5 leaves major diameter disk DL, be located at the register pin 62a on the positioning sliding block 61 that the Y2 direction moves, 62b makes major diameter disk DL return to the Y2 direction.In order to prevent this phenomenon, in this embodiment, under state shown in Figure 9, locking pin 65 embeds among the second lock portion 61g, positioning sliding block 61 is not returned to the Y2 direction, and lock.Register pin 62a, 62b can prevent that major diameter disk DL is pushed back, and therefore, can keep the major diameter disk DL part 15c that is positioned, the state of 15d location.
Like this, a pair of register pin 62a, 62b can not return to the Y2 direction from the position of Fig. 9, nor can be by returning spring 72, afterburning simply the promotion.Therefore, utilize this register pin 62a, 62b can be positioned at major diameter disk DL on the panoramic table T.
When reaching Fig. 9 state, as mentioned above, because trigger lever 25 moves some distances a little towards 4. direction, utilize the B of powershift mechanism, the first switching lever 22 that is connected with above-mentioned trigger lever 25, by connecting pin 24, can rotate a bit a little to counter clockwise direction (the 5. direction of Fig. 4 (B)).Shown in Fig. 4 (B), to the first recess 22b that switches lever 22 that 5. direction is rotated, compress the trigger projection 21a of change gear 21, make change gear 21, rotate a bit a little to the CW direction.
As a result, shown in Fig. 4 (B) and Fig. 6 (B), be located at the front end 34a that the 3rd cam 21d on the change gear 21 leaves lever arm 34, lever arm 34 becomes free state.Because driven wheel 32 is rotated to clockwise direction by driven by motor, friction force makes the lever arm that is in free state to the clockwise direction activity.At this moment, because axle 35a moves, arrive the second targeting part 36b in the first targeting part 36a of the second switching lever 23, having limited axle 35a can not be to the clockwise direction activity, and therefore, idling gear 35 and change gear 21 engagements are kept this state.Like this, the rotating force of driven wheel 32 by idling gear 35, passes to change gear 21, and change gear 21 is rotated to the CW direction.
When change gear 21 from the state of Fig. 4 (B) when the CW direction is rotated, the second cam 21c of the change gear 21 shown in Fig. 6 (A) drives second and switches lever 23, is fulcrum with axle 23a, rotates to counterclockwise (the 6. direction of Fig. 5 (A)).At Fig. 5 (A) constantly, according to the shape of making the first cam 21b on change gear 21, power is not passed to first and switches on the lever 22, and the first switching lever 22 stops at the state shown in Fig. 4 (B) (from Fig. 4 (A), a little to move any position of 5. direction), only drive second and switch lever 23, to 6. direction rotation.
Switch lever 23 when 6. direction is rotated when second, the loading slider 28 that is connected with it moves to the Y2 direction, and gathering sill 28b makes roller arms 41 to counterclockwise rotating, and roller leaves major diameter disk DL, is removed to the carrying capacity of major diameter disk DL.Simultaneously, the displacing force to the Y2 direction of loading slider 28 makes rotating cam 81, from the state of Figure 16, to counterclockwise rotating.The clamping cam 81a of rotating cam 81 leaves by compressing tablet 15b, and clamp arm 15 descends, and is clamped the core of major diameter disk DL by binding clasp 16 and panoramic table T.
At this moment, utilize, can make under Figure 16 state from the rotary motion trace of the clamp arm 15 of Figure 16 to Figure 17, with the keeper 15c of major diameter disk DL location, 15d, under the clamped condition of Figure 17, the excircle from major diameter disk DL leaves a bit a little.
That is to say, move to Fig. 9 state at major diameter disk DL from the state of Fig. 8, the second lock portion 61g of positioning sliding block 61 is locked after pin 65 lockings, shown in Fig. 6 (B), idling gear 35 and change gear 21 engagements, change gear 21 is driven to the CW direction and rotates, and second switches lever 23 moves to 6. direction.Meanwhile, loading slider 28 moves to the Y2 direction, and roller arms 41 is rotated downwards, and the power of sending to that acts on the major diameter disk DL is removed, and DL is clamped for the major diameter disk.Because at this moment locking pin 65 does not make positioning sliding block 61 return to the Y2 direction, and lock, carrying capacity is cut off, roller 5 and the cut major diameter disk of roller flange 44 holding forces DL, before the clamping action finishes, do not return, therefore to the Y2 direction, along with the decline of roller 5, the center of major diameter disk DL can be clamped on the panoramic table T reliably.
After above-mentioned disc clamp action finished, the first cam 21b of the change gear 21 that is rotated further made first to switch lever 22, like that, rotates (referring to Fig. 6 (A)) to counter clockwise direction shown in Fig. 5 (B).Therefore, as shown in figure 10, switch the trigger lever 25 that lever 22 is connected, move a long distance to the Y1 direction with first.The tooth bar 25d that forms on trigger lever 25, drive controlling solid of revolution 75 rotates to clockwise direction (direction 7.).The driving cam 75b that on control solid of revolution 75, makes, compress the end 68a of actuating arm 68, actuating arm 68, to counterclockwise rotating significantly, the positioning sliding block 61 that is connected with actuating arm 68, as among Fig. 1 O 8. shown in, move to the Y1 direction, register pin 62a, 62b hide to the position of leaving major diameter disk DL circumferential edges.
As mentioned above, as shown in Figure 9, when positioning sliding block 61 was locked by locking pin 65, the driving force of roller 5 was cut off, and large diameter disk DL is clamped on the panoramic table T, and after the clamping, positioning sliding block 61 is directly hidden shown in 8. like that.
When hiding after action finishes of above-mentioned positioning sliding block 61, change gear 21 continues to rotate to the CW direction, can switch the state that lever 22 remain on Fig. 5 (B) with first.Utilize the second cam 21c, can make second to switch lever 23, again to (the 9. direction of Fig. 5 (C)) rotation counterclockwise.Therefore, loading slider 28 moves to terminal to the Y2 direction, and shown in Fig. 5 (C), gathering sill 28b makes roller arms 41 again to counterclockwise rotating.At this moment move by the terminal of loading slider 28, as shown in figure 19 to the Y2 direction again,, can drive the lock cam 81b of rotating cam 81,, remove the locking of disk drive U to counterclockwise rotating, make disk drive U, be bearing in the floating state of going up of elasticity by vibration damper etc.
When loading slider 28 when the Y2 direction moves to the final position, second switches the yielding targeting part 36c of lever 23, arrives the position of the axle 35a of idling gear 35.Because under this state, driven wheel 32 rotates to clockwise direction, the active actions of lever arm 34 moves a 35a in above-mentioned yielding targeting part 36c, and idling gear 35 breaks away from change gear 21 fully.Under this state, turn to the roller arms 41 of Fig. 5 (C) position, switch SW 4 is switched to on-state, motor quits work.
And major diameter disk DL is driven rotation, can reappear the signal that is recorded on the major diameter disk DL.
(discharging operation of major diameter disk DL)
When output disk was discharged order, under Fig. 5 (C) state, motor opposite direction when importing with disk began to rotate, and drove gear wheel in large diameter 33 and driven wheel 32 to counterclockwise rotating.Under the state of Fig. 5 (C), because the axle 35a of idling gear 35 is arranged in the yielding targeting part 36c of the second switching lever 23, along with driven wheel 32 rotates to counter clockwise direction, also to counterclockwise rotating, idling gear 35 meshes with change gear 21 lever arm 34.And change gear 21 towards CCW directions are rotated.
At the initial stage that change gear 21 towards CCW directions begin to rotate, the second cam 21c of change gear 21 drives second and switches lever 23, rotates to clockwise direction, arrives position shown in Fig. 5 (B).During from Fig. 5 (C) to Fig. 5 (B), the second switching lever 23 to clockwise direction is rotated drives loading slider 28, moves to the Y1 direction.Like this, roller arms 41 is rotated a bit a little to clockwise direction, and roller 5 contacts with the lower surface of major diameter disk DL in clamping.In addition, the action of the latch mechanism of disk drive U will be locked (as shown in figure 18) by the disk drive U of state on elasticity is floating.
After, change gear 21 by the second cam 21c, makes second to switch the position that lever 23 remains on Fig. 5 (B) to the rotation of CCW direction.Under this state, the first cam 21b drives first and switches lever 22, rotates to clockwise direction.Thereby, switch the trigger lever 25 that lever 22 is connected with first, move to the Y2 direction.At this moment, make the tooth bar 25d on trigger lever 25, make control solid of revolution 75, from the state of Figure 10 to counterclockwise rotating.
When control solid of revolution 75, from the position of Figure 10, when counter clockwise direction is rotated, be the end 68a that driving cam 75b breaks away from actuating arm 68 at first, the clockwise rotating force by returning spring 72 produces acts on the actuating arm 68.Therefore, the positioning sliding block 61 that is connected with actuating arm 68 is accepted the elasticity recovery power by above-mentioned returning spring 72 generations, moves to the Y2 direction.As shown in figure 11, be located at the register pin 62a on the positioning sliding block 61,62b contacts with the end of Y1 side of major diameter disk DL on being clamped in panoramic table T.In addition, to counterclockwise rotating a little when a bit, locking control cam 75a compresses locking lever 63 towards the X2 direction to control solid of revolution 75 from Figure 10.Therefore, as register pin 62a, 62b is with after major diameter disk DL contacts, and locking pin 65 leaves the second lock portion 61g.Like this, the elasticity recovery power by above-mentioned returning spring 72 produces acts on the major diameter disk DL, because major diameter disk DL is clamped, it can not return to the Y2 direction.
After this, first switches lever 22 rotates to clockwise direction, and trigger lever 25 is moved to the Y2 direction again.When the second switching lever 23 returned back to position shown in Fig. 5 (A), tooth bar 25d made control solid of revolution 75 again to counterclockwise rotating.As shown in figure 11, locking control cam 75a deviates from from the left end 63c that locks lever 63, and locking lever 63 is subjected to locking spring 64 to the added power of X1 direction.Therefore, as shown in figure 11, locking pin 65 engages with the second lock portion 61g of positioning sliding block 61, and positioning sliding block 61 can not move to the Y2 direction, and locks.
As shown in figure 11, as register pin 62a, 62b contacts with the front edge of major diameter disk DL, and positioning sliding block 61 is when being locked, and first switches lever 22 stops with the posture of Fig. 5 (A).After, by the rotation of change gear 21 to the CCW direction, first switches the position that lever 22 remains on above-mentioned Fig. 5 (A), and secondly, the second cam 21c makes second to switch lever 23, rotates a bit (shown in Fig. 4 (B)) a little to clockwise direction.
When the second switching lever 23, when clockwise direction was rotated, second switches lever 23 drove loading slider 28, moves to the Y1 direction.When loading slider 28 when the Y1 direction moves, as shown in figure 16, this loading slider 28 raises the clamp arm 15 of disk drive U, binding clasp 16 leaves panoramic table T, the clamping of major diameter disk DL is removed.Probably meanwhile, because the gathering sill 28b of loading slider 28 is open with pin 38, roller arms 41 is promoted by the elastic force of spring 43, rotates to clockwise direction, and disk is clamped by roller 5 and roller flange 44.Simultaneously, pass to the driving force of follower gear 45, roller 5 is rotated to clockwise direction, begin major diameter disk DL is discharged to the Y2 direction by gear wheel in large diameter 33.
After, shown in Fig. 4 (A), because the second first targeting part 36a that switches lever 23 arrives the position of axle 35a, by the driven wheel 32 that rotates to counter clockwise direction, make lever arm 34 to action counterclockwise, idling gear 35 breaks away from change gear 21, and change gear 21 stops with the posture of Fig. 4 (A).After, gear wheel in large diameter 33 is rotated further, and the rotating force of roller 5 makes major diameter disk DL discharge to the Y2 direction.
As shown in figure 11, in the disk discharging operation, the second lock portion 61g at positioning sliding block 61, under the state that the pin 65 that is locked is locked, because disc clamp removed, after disc clamp is removed, and before major diameter disk DL clamped fully by roller 5 and roller flange 44, returning spring 72 can not make positioning sliding block 61 return to the Y2 direction.Therefore, before roller 5 and roller flange 44 were clamped major diameter disk DL, major diameter disk DL was not subjected to the effect of the power that flies out to the Y2 direction.
Secondly, as shown in figure 12, when the rotating force of roller 5 makes major diameter disk DL when the Y2 direction is discharged, the circumferential edges of major diameter disk DL will insert the test pin 8 and 9 of the A of testing agency and push open to the left and right.Like this, the locking actuating arm 66 that is connected with test pin 8 also rotates to clockwise direction.As a result, be located at the drive pin 67 on the locking actuating arm 66, drive locking lever 63 to the motion of X2 direction, locking pin 65 leaves the second lock portion 61g, the lock release of positioning sliding block 61.Simultaneously, the elastic force of returning spring 72 makes positioning sliding block 61 return to the Y2 direction, returns back to original state shown in Figure 7.
Insert the A of testing agency when detecting, when major diameter disk DL was expelled to institute's allocation, motor stopped, and the B of powershift mechanism also stops under the original state shown in Fig. 4 (A).
(insert action of minor diameter disk DS)
Fig. 3 represents the insertion state of the Center-to-Center line O-O unanimity of minor diameter disk DS.At this moment, utilize and insert the A of testing agency, test pin 8 and 9 is pushed open a bit, detector switch SW1 and SW2 disconnect simultaneously.As shown in figure 13, exist the possibility of minor diameter disk DS from inserting near the position of the X1 side of inserting mouthful 2a again.At this moment, have only the test pin 8 in left side, press to the X1 direction, and have only detector switch SW1 to disconnect.Perhaps, minor diameter disk DS from the position near the X2 side, inserts among mouthful 2a, and at this moment, the test pin 9 on right side is pressed towards the X2 direction, has only detector switch SW2 to disconnect.
Under above-mentioned which state, when SW1 or SW2 disconnection, motor begins to rotate, under the state of Fig. 4 (A), gear wheel in large diameter 33 rotates to clockwise direction, roller 5 is to counterclockwise rotating, and minor diameter disk DS is clamped by roller 5 and roller flange 44, sends to the Y1 direction.
Under waiting status shown in Figure 7, as above-mentioned, positioning sliding block 61 is by locking pin 65 lockings.And for example shown in Figure 13, when minor diameter disk DS inserts from the position near the X1 side, when test pin 8 is pressed to the X1 direction, test pin 8 makes the locking actuating arm 66 of connection, rotate to clockwise direction, utilization is located at the drive pin 67 of locking on the actuating arm 66 and will locks lever 63 and press to the X2 direction, and locking pin 65 leaves the first lock portion 61f, the lock release of positioning sliding block 61.Again, as shown in figure 14, when the turning power of roller 5 makes minor diameter disk DS when the Y1 direction is sent to, because the disk diameter is little, test pin 8 directly returns to the X2 direction, and locking actuating arm 66 also returns to counter clockwise direction.Therefore, at minor diameter disk DS near register pin 62a, under the state of 62b, as shown in figure 14, the first lock portion 61f of positioning sliding block 61, pin 65 locking must be locked.
Under the state of positioning sliding block 61 locking, the register pin 62a and the 62b that establish thereon are in minor diameter disk DS are positioned at position on the panoramic table T.Therefore, by roller 5 minor diameter disk DS that carries and a pair of register pin 62a that is in locking state under, 62b contacts, and core is on the center consistent location with panoramic table T and binding clasp 16.
And for example shown in Figure 13, when near left to the position insert minor diameter disk DS, when still sending to roller 5, perhaps, from inserting minor diameter disk DS near the position of right, when still sending to roller 5, the front end of minor diameter disk DS only contacts with the register pin 62a or the 62b of any example.But because the center of roller 5 is tiny shape, the minor diameter disk DS that sends near a side is a fulcrum with the register pin 62a or the 62b of an end in contact, proofreaies and correct posture voluntarily.Shown in Figure 14 solid line, minor diameter disk DS arrives and a pair of register pin 62a, the 62b position contacting, and reliably be positioned on the panoramic table.
As shown in figure 14, when minor diameter disk DS by register pin 62a, in 62b when location,, the front end on the center line O-O of minor diameter disk DS compresses the test pin 58 that is located on the detection and localization arm 56 towards the Y1 direction.Because positioning sliding block 61 at locking state, compresses the detection and localization arm 56 of test pin 58, is fulcrum with the drive pin 61d (the 3rd web member) that is located on the positioning sliding block 61, to counterclockwise rotating, detection and localization arm 56 becomes first detection position.Therefore, the trigger arm 54 that is connected with positioning sliding block 61 is rotated to clockwise direction (3. direction).
Identical with the importing of major diameter disk DL, trigger arm 54 makes trigger lever 25 to the 3. rotation of direction, and is mobile a little to the Y1 direction, and like this, shown in Fig. 4 (B), first of the B of powershift mechanism switches lever 22 to 5. direction is a little mobile a little.Shown in Fig. 6 (B), idling gear 35 and change gear 21 engagements drive change gear 21 and rotate to the CW direction.
Change gear 21 is to the rotation of CW direction, at first, the second cam 21c by change gear 21, make second to switch the 6. direction rotation of lever 23 to Fig. 5 (A), loading slider 28 moves to the Y2 direction, gathering sill 28b makes roller arms 41 to counterclockwise rotating, and roller 5 is sent to the power of sending to of minor diameter disk DS and removes.Approximately meanwhile, binding clasp 16 and panoramic table T press from both sides position minor diameter disk DS and clamp it.At this moment, because the first lock portion 61f of positioning sliding block 61, by locking pin 65 lockings, roller 5 leaves disk, after the disk power of clamping is removed, clamp this to minor diameter disk DS during, do not act on the minor diameter disk DS to the expulsion force of Y2 direction.
When the second switching lever 23, after Fig. 5 (A) position stopped, the first cam 21b made first to switch lever 22 to counterclockwise rotating, and reaches the position of Fig. 5 (B).At this moment, the trigger lever 25 that is connected with the first switching lever 22 is driven, and moves to the Y1 direction.This trigger lever 25 from tooth bar 25d, passes to control solid of revolution 75 to the displacing force of Y1 direction, and control solid of revolution 75 is driven, and rotates to clockwise direction from state shown in Figure 14.
When control solid of revolution 75, when clockwise direction is rotated, initial from Figure 14 state, locking control cam 75a drives locking lever 63, shifts to the X2 direction, and locking pin 65 leaves the first lock portion 61f, the lock release of positioning sliding block 61.After, the driving cam 75b of control solid of revolution 75 compresses the end 68a of actuating arm 68, and actuating arm 68 is to counterclockwise rotating.As a result, the positioning sliding block 61 that is connected with actuating arm 68 as shown in figure 15, is driven to Y1 (8. direction) and moves, register pin 62a, and 62b arrives the escape hole that leaves minor diameter disk DS.
At this moment, the detection and localization arm 56 that is connected with positioning sliding block 61 slide block 61 that is positioned compresses to the Y1 direction, detection and localization arm 56 is a fulcrum with connecting pin 57, to counterclockwise rotating, moves to the identical position of state that finishes with major diameter disk DL shown in Figure 10 filling.
Shown in Fig. 5 (B), switch lever 22 when counter clockwise direction is rotated first, shown in Fig. 5 (C), by the rotation of change gear 21 to the CW direction, second switches lever 23 to counterclockwise rotating, make roller arms 41 when counterclockwise rotating in loading slider 28, the lock release of disk drive becomes the floating state of going up.Simultaneously, the second yielding targeting part 36c that switches thick stick stalk 23 makes idling gear 35 change gear 21 and separate with cutting, and motor stops operating.
(discharging operation of minor diameter disk DS)
When output minor diameter disk DS discharged order, under state shown in Fig. 5 (C), motor-driven gear wheel in large diameter 33 was to counterclockwise rotating, lever arm 34 is also to counterclockwise rotating, idling gear 35 and change gear 21 engagements drive change gear 21, rotate to the CCW direction.
Change gear is to the rotation of CCW direction, at first, make second to switch lever 23, from Fig. 5 (C) position, clockwise direction turns to position shown in Fig. 5 (B), this fashionable dress is cut out slide block 28 and is moved to the Y1 direction, and roller arms 41 is rotated to clockwise direction, the lower surface position contacting of the minor diameter disk DS of roller 5 arrival and clamped condition.Disk drive becomes locking state from the floating state of going up of elasticity.
After this, second switches the position that lever 23 stops at Fig. 5 (B), and then, change gear 21 makes first to switch lever 22 to the revolution of CCW direction, turns to the state of Fig. 5 (A) to clockwise direction.At this moment, switch the trigger lever 25 that lever 22 is connected with first, move to the Y2 direction, the tooth bar 25d of trigger lever 25 makes control solid of revolution 75, to counterclockwise rotating.
When control solid of revolution 75 from state shown in Figure 15, when counter clockwise direction rotated, make the driving cam 75b on control solid of revolution 75, deviate from from the end 68a of actuating arm 68, rotate to clockwise direction by the elastic force promotion actuating arm 68 of returning spring 72.Therefore, the positioning sliding block 61 that is connected with actuating arm 68 also returns to the Y2 direction.Before positioning sliding block 61 returns back to position shown in Figure 14, the locking control cam 75a of control solid of revolution 75, deviate from from the left end 63c of locking lever 63, locking lever 63, return to the X1 direction by locking spring 64, locking pin 65 engages with the first lock portion 61f, and positioning sliding block 61 is locked at position shown in Figure 14.
