Secondly, be linked on the formation of the armite 54 between the 1st oscillating structural member 45 and toothed disc described later, utilization is linked to the 1st armite 54a of the 1st oscillating structural member 45 with coupling member 55 and is subjected to the combination of the 2nd armite 54b that draft helical spring 56 bullets push away and can stretches the mechanism's safety when guaranteeing to transfer major diameter disc D1 and minor diameter disc D2.
Fig. 7 is the stereographic map of formation of looking down the end of aforementioned the 2nd armite 54b from the device back side, and the through hole 19b of the through hole 54b-1 of the 2nd armite 54b, the rotary plate 19a of disc supporting arm 19 and the through hole 59a of toothed disc 59 are simultaneously with rotating mode axle Zhi Yushu shotpin 57.On the other hand, the center pit 19c of disc supporting arm 19 and the center pit 59b of toothed disc 59 axle Zhi Yuyi end simultaneously are fixed on the rivet pin 20 of bottom panel 6, and the hooking sheet 19d of aforementioned rotary plate 19a ends window 59c in the face of the card of toothed disc 59 and is integral.
The a part of formative gear 59d of the outer rim of the side of facing box casket 2 of aforesaid gears dish 59, the outer rim relative with it then forms the switch activated section 59e.59f of portion.The limit switch 60 that utilizes the aforementioned switches startup section 59e.59f of portion to connect is the wiring substrates (indicating on the figure) that are installed on the bottom surface that is provided in box casket 2, utilizes aforementioned switches to start the section 59e.59f of portion and drives its switching knob 60a.
Secondly, at so that the mechanism that guid arm 25 is swung to purpose describe.The axle backing pin 26 of the cardinal extremity of the swing fulcrum of this guid arm 25 is the back side that is equipped on bottom panel 6, and roller support plate 62 is being fixed in its end.Because this roller support plate 62 is being installed draft helical spring shown in Figure 3 63, produce the clockwise bullet thrust of this figure, whereby, guid arm 25 can be toppled over towards heart direction.Be equipped on the formation of 62 pairs of rollers 64 of aforementioned roller support plate, as shown in Figure 8, large-diameter portion 64a and minor diameter 64b are coaxial.
Among this figure, the rack slide 65 that sets along the side wall inner surface of box casket 2 has the rack pinion 65a of meshing gear 59d in toothed disc 59, along with forward-reverse is carried out in the rotation of toothed disc 59 synchronously.The downside of the pars intermedia of rack slide 65 forms low level fairlead 65b, and upside then forms high-order fairlead 65c, the large-diameter portion 64a of aforementioned pair of roller 64 of low level fairlead 65b guiding, and high-order fairlead 65c then guides minor diameter 64b.
The organize factor of this kind formation is to utilize the forward-reverse of loading slider 43 to carry out action, and as shown in Figure 3, this driving mechanism is equipped on the bight at the device back side.Secondly, the revolving force of the worm gear 67 of the output shaft of the loading motor 66 of the power source of driving mechanism is to utilize by the bidentate wheel gear train that 68.69.70 constituted, and under the situation of slowing down, conveys to gear wheel in large diameter from small diameter gear in regular turn.Secondly, the small diameter gear of the bidentate of the rack pinion 43a from meshing in loading slider 43 wheel 70 is passed on driving force and is made loading slider 43 forward-reverses.
Secondly, the action form at the optical disc apparatus of the present invention 1 with formation as above describes.On the formation of above-mentioned optical disc apparatus of the present invention 1, can transfer major diameter disc D1 and minor diameter disc D2, at first, with reference to Fig. 9 to Figure 22, handover form at major diameter disc D1 describes, and with reference to Figure 23 to Figure 36, describes at the handover form of minor diameter disc D2.
Fig. 9 to Figure 15 is the planimetric map at main position that indicates the formation on the surface be exposed to bottom panel 6 with solid line, and the main position of the formation at the back side of bottom panel 6 is represented by dotted lines.In addition, Figure 16 to Figure 22 is the ground plan at main position that indicates the formation at the back side be exposed to bottom panel 6 with solid line, and the formation on the surface of bottom panel 6 is represented by dotted lines.In addition, among Fig. 9 to Figure 15, cam ditch 43e.43c reaches and should be presented in the figure from untie-sell 7a.7b is former, yet, for convenience of description, illustrate in order to understanding.
Fig. 9 and Figure 16 wait the holding state that major diameter disc D1 inserts from the notch 3a of panel 3, and each arm is in original state and static.At this moment, guid arm 25 is at the back side of bottom panel 6, the large-diameter portion 64a of roller 64 that is fixed on the roller support plate 62 of aforementioned axis backing pin 26 is the low level fairlead 65b that are connected to Fig. 8 and rack slide 65 shown in Figure 16, and guid arm 25 stops at the position of the full swing position of centripetal direction towards centrifugal direction swing specified quantitative.
If the insertion of disc is waited in the full swing position that guid arm 25 stops at centripetal direction on the formation, when then minor diameter disc D2 being inserted near the device left side, minor diameter disc D2 can enter the left side of support member 25a and can't transfer minor diameter disc D2, in order to prevent said circumstances, so the insertion of disc is waited in the full swing position that makes guid arm 25 stop at centripetal direction towards the position of centrifugal direction swing specified quantitative.
Secondly, guid arm 27 pushes away because its base end part is subjected to the bullet of draft helical spring 53, hold the support member 27a that acts on front end towards trying hard to keep of heart direction swing, yet, be still in the location because be linked to the 3rd oscillating structural member 51 of a backing pin 27b, because of this guid arm 27 keeps the static state shown in Figure 9 that is in.Because be installed in the function of the binding metal wire 52 performance retainers between the effect pin 51a of the 1st oscillating structural member 45 of stationary state and the 3rd oscillating structural member 51, so can stop the swing of the 3rd oscillating structural member 51.
Same, pass on disc supporting arm 19, guid arm 29, guid arm 35 and the loading arm 22 of power to keep static and be in state shown in Figure 9 along with moving of loading slider 43.In addition, under the guiding of the cam ditch 43e of loading slider 43, crane 7 be positioned at the 43e-1 of low level portion of this cam ditch 43e from untie-sell 7a, on the other hand, under the guiding of the cam ditch 48c of driven sliding block 48, crane 7 be positioned at the 48c-1 of low level portion of this cam ditch 48c from untie-sell 7b, so crane 7 is in the minimum state that drops to shown in Figure 37 (A).
Figure 10 and Figure 17 front that to be the operator insert major diameter disc D1 and this major diameter disc D1 from the notch 3a of panel 3 is connected to the state of the support member 29a of the holder 21 of disc supporting arm 19 and guid arm 29.At this moment, the support member 25a of the front end of major diameter disc D1 pushing guid arm 25, and swing towards centrifugal direction from the position shown in the dotted line of Figure 10.At this moment, the sidepiece of major diameter disc D1 pushes the card not-go-end 41a of portion of lead-in wire 41 and slides towards direction shown in the arrow of this figure.Whereby, locking bar 37 is under the traction of lead-in wire 41, and the grab 37a of its front end is towards the swing of direction shown in the arrow of this figure, and the scope that breaks away from the tongue piece 29b of the front end that is limited to guid arm 29.
Figure 11 and Figure 18 are the states that the operator further inserts major diameter disc D1 under above-mentioned state, and under the pushing of major diameter disc D1, disc supporting arm 19, guid arm 25 and guid arm 29 are swung towards centrifugal direction.Therefore, the base portion of disc supporting arm 19 as fulcrum, rotates to the position of Figure 39 (B) from the position of Figure 39 (A) with rivet pin 20, and utilizes the switch activated section 59e of portion of toothed disc 59 to start limit switch 60.In addition, this moment, meshing 65 of rack slides in toothed disc 59 can advance a little.
According to the signal from the limit switch 60 that utilizes the aforementioned switches startup section 59e of portion to be started, the electric current that has low level voltage at this moment flows through loading motor 66.Whereby, loading slider 43 retreats and traction link 24, makes loading arm 22 be rocked to the position of the dotted line of this figure, and the sidepiece of the loading roller 22a butt major diameter disc D1 of front end also stops.
Herein, the current potential of the electric current of aforementioned electronegative potential is that benchmark is set with the necessary current potential of transferring aftermentioned minor diameter disc D2, this time point may cause transfer mechanism to break down if the big moment that flows through to produce the necessity that moves into major diameter disc D1 is the electric current of the noble potential of purpose.That is, among Figure 11, because load roller 22a the component F1a that pushing produced, and the component F1b that pushing produced of the support member 25a of guid arm 25 center that roughly is positioned at major diameter disc D1 pay closely, so it is made a concerted effort minimum and can not produce the power towards the propelling of immigration direction with major diameter disc D1.And state shown in Figure 11 is that the front end of guid arm 29 is pushed away towards heart direction bullet and is in the state of the rear lateral portion of support member 29a pushing major diameter disc D1.
Under this situation, make the electric current of transferring the necessary noble potential of major diameter disc D1 flow through loading motor 66, then loading arm 22 keeps stopping under the state of clamping major diameter disc D1, and stops to move into action.If continue this state, the danger that may cause that the gear train breakage of transfer mechanism for example or loading motor 66 burn etc.For fear of above-mentioned danger, this time point makes the electric current of transferring the necessary electronegative potential of minor diameter disc D2 flow through loading motor 66.
In addition, electric current at electronegative potential flows through under the aforesaid state of loading motor 66, when having only the driving force of loading motor 66, can't rotate loading arm 22 because of the load of major diameter disc D1, so can not carry out the transfer movement of major diameter disc D1, when the operator pushed major diameter disc D1, the driving force of loading motor 66 added operator's insertion force, just carries out the transfer movement of major diameter disc D1.
Figure 12 and Figure 19 are the states that the operator further inserts major diameter disc D1 under above-mentioned state, and the toothed disc 59 of the base portion of disc supporting arm 19 further is rotated.Whereby, armite 54 is drawn, and the 1st oscillating structural member 45 is swung as fulcrum with rivet pin 44 and made from untie-sell 45a and retreat because flow through electronegative potential electric current loading motor 66 driving force and be in the loading slider 43 that is played push mode and also retreat.
When arriving this action, guid arm 29 is removed the support of support member 29a to major diameter disc D1 towards the centrifugal direction swing.Because under the state of Figure 11, what be positioned at guid arm 29 on the dip plane of rearward end of guiding ditch 43c-1 of loading slider 43 affords the effect of aforementioned dip plane from untie-sell 29d along with retreating of loading slider 43.
Along with the swing of the 1st oscillating structural member 45 as the aforementioned, make the 3rd oscillating structural member 51 that swing is subjected to regulation under the effect of draft helical spring 53 because of linking metal wire 52, swing as fulcrum with rivet pin 50.Whereby, guid arm 27 is towards the swing of heart direction, and the support member 27a of its front end is supporting the rear lateral portion of major diameter disc D1.At this moment, connecting rod 24 is drawn because of retreating of loading slider 43, and loading arm 22 is towards the swing of heart direction, and the loading roller 22a butt of front end is also supported the front side portion of major diameter disc D1.In addition, because crane 7 is the laterally mobile state of the 43e-1 of low level portion that is in cam ditch 43e from untie-sell 7a, so this crane 7 stops at the position of Figure 37 (A).
On the other hand, the toothed disc 59 of the base portion of disc supporting arm 19 rotates to the position shown in Figure 39 (C), and the switch activated section 59f of portion oppositely starts the switching knob 60a of limit switch 60.The current switching that the signal of foundation limit switch 60 at this moment will flow through loading motor 66 becomes noble potential, produces to move into the necessary moment of major diameter disc D1.Secondly because load roller 22a the component F1a that pushing produced, and the component F1b that pushing produced of the support member 25a of guid arm 25 become big, generation can be towards moving into the F2 that makes a concerted effort that direction advances, and utilize loading motor 66 to begin to carry out automatic loading.
Figure 13 and Figure 20 utilize loading motor 66 to begin to carry out automatic loading and the state that moves into major diameter disc D1.Loading slider 43 further retreats from the state of Figure 12, and then 43 the rake from untie-sell 29d from loading slider of guid arm 29 enters guiding ditch 43c-1.Whereby, further towards the centrifugal direction swing, the support member 29a of front end is in the state of the sidepiece that does not contact major diameter disc D1 to guid arm 29.In addition, Figure 40 (A)～(D) is the continuous action form of guid arm 29.
In addition, connecting rod 24 is drawn because of retreating of loading slider 43, and loading arm 22 beginnings are swung towards heart direction.Figure 41 (A)～(D) is the continuous swing state of loading arm 22, and the state of loading arm 22 shown in Figure 12 is the states that are equivalent to enter from the original state of Figure 41 (A) Figure 41 (B).
Be responsible for the connecting rod 24 of the swing of aforementioned loading arm 22, as previously described, because be fixed on connecting rod 24 front end be the guiding line of rabbet joint 49a that induces ditch 43d and guide plate 49 that is inserted in loading slider 43 from untie-sell 24a, loading slider 43 is if retreat, then can be in the state of the sidewall clamping of the dip plane of the rear end of being induced ditch 43d and guiding line of rabbet joint 49a from untie-sell 24a, can retreat along with retreating of loading slider 43 from untie-sell 24a, and connecting rod 24 is drawn and make loading arm 22 swing.
Along with loading slider 43 retreats to position shown in Figure 13, upper end horizontal part 43b-1 upwards the pushing away of guiding ditch 43b with the 1st oscillating structural member 45 from untie-sell 45a, and the 1st oscillating structural member 45 is swung as fulcrum with rivet pin 44, and toothed disc 59 is rotated via armite 54.Whereby, disc supporting arm 19 is swung towards centrifugal direction, that is, supporting the holder 21 of the rearward end of major diameter disc D1 to retreat synchronously with the immigration of major diameter disc D1.In addition, this time point, because the 2nd oscillating structural member 47 is the state that is in the vertical component effect slip of guiding ditch 43b from untie-sell 47a, the 2nd oscillating structural member 47 is in static state, driven sliding block 48 also is in static state.
The stroke of the state that enters Figure 13 from Figure 12, be subjected to the guid arm 27 that the bullet of draft helical spring 53 pushes away, the support member 27a of its front end is shown in Fig. 13, be pushed back along with the immigration of major diameter disc D1, and the card that is connected to lever arm 42 ends tongue piece 42a and stops.At this moment, because 51 of the 3rd oscillating structural members are swung a little, its effect pin 51a then moves towards heart direction in the through hole 48b of the end of static driven sliding block 48, so link 52 states that are in a little distortion of metal wire.
On the other hand, the support member 25a of guid arm 25 is supporting the front side portion of major diameter disc D1, and the high-order fairlead 65c of the rack slide 65 that advances because of the rotation of aforesaid gears dish 59 is in the state of the minor diameter 64b that leaves two rollers 64.In addition, the crane 7 of this moment be in the state that the 43e-1 of low level portion of cam ditch 43e laterally moves from untie-sell 7a because driven sliding block 48 keeps static, so crane 7 still stops at the position of Figure 37 (A).
To be loading slider 43 further retreat and traction link 24 from the state of Figure 13 and Figure 20 for Figure 14 and Figure 21, and 22 of loading arms are rocked to the position shown in Figure 41 (C) and make the center of center pit D1a of major diameter disc D1 of immigration and the center of clamping head 9 become consistent state.On the other hand because guid arm 29 be in the state that the guiding ditch 43c-1 of loading slider 43 directly advances from untie-sell 29d, guid arm 29 and guid arm 35 are still in position shown in Figure 14.At this moment, the outer rim of support member 29a and support member 35a butt major diameter disc D1 also positions, and makes the center pit D1a of major diameter disc D1 and the position of clamping head 9 can correctly become unanimity.
The 1st oscillating structural member 45 upwards pushed away and enter vertical component effect 43b-3 along with retreating of loading slider 43 by upper end horizontal part 43b-1 from untie-sell 45a, so the 1st oscillating structural member 45 is rocked to the position shown in the figure, toothed disc 59 is along with armite 54 is rotated, and disc supporting arm 19 is also swung towards centrifugal direction.The rotation of aforesaid gears dish 59 is advanced further rack slide 65, and the minor diameter 64b of two rollers 64 is positioned on the high-order fairlead 65c, so guid arm 25 is significantly swung towards centrifugal direction, and removes the state that its support member 25a props up the outer rim that is held in major diameter disc D1.Whereby, guid arm 25 is avoided the state that is in the top that is not present in crane 7 to the side of crane 7, so the anxiety that crane 7 that rises and guid arm 25 do not have conflict.
At this moment, the support member 27a of major diameter disc D1 pushing guid arm 27, yet, the card that this support member 27a is connected to lever arm 42 ends tongue piece 42a and guarantees to be positioned at stop position, therefore, this time point can become unanimity with respect to the center of the horizontal direction of the clamping head 9 of major diameter disc D1.On the other hand, can determine because of the loading roller 22a of the holder 21 of the static disc supporting arm 19 of state shown in Figure 14 and loading arm 22 with respect to the center of the vertical direction of the clamping head 9 of major diameter disc D1.
As mentioned above, according to optical disc apparatus of the present invention, till the state that is loaded into Figure 14 automatically of beginning major diameter disc D1, at least 3 places of the outer rim of this major diameter disc D1 obtain the support of aforementioned a plurality of arms and be moved into to device inner, but and be still in the position of the center pit D1a of clamping head 9 clampings.
In addition, enter the stroke of Figure 14 from Figure 13, the cam ditch 43e of loading slider 43 retreats the state that makes the entering rake 43e-2 from untie-sell 7a from the 43e-1 of low level portion of crane 7 and be in rising.On the other hand, the 2nd oscillating structural member 47 then arrive lower end horizontal part 43b-2 from untie-sell 47a from the vertical component effect 43b-3 of loading slider 43, and make the 2nd oscillating structural member 47 towards the centrifugal direction swing, along with effect pin 47b moves horizontally driven sliding block 48, cam ditch 48c also moves horizontally.Whereby, the entering rake 48c-2 of crane 7 and be in the state of rising from untie-sell 7b from the 48c-1 of low level portion, crane 7 begins to rise shown in Figure 37 (B).
Figure 15 and Figure 22 are that clamping head 9 clampings the center pit D1a of major diameter disc D1 and are in the final state that can drive major diameter disc D1.Before arriving this state, must make disc supporting arm 19, loading arm 22 and the guid arm 27 of supporting major diameter disc D1 swing a little and remove the support of disc towards centrifugal direction, just can not hinder the rotation of major diameter disc D1.
That is, loading slider 43 from the state of Figure 14 further retreat and the position that stops on, because the eccentric traverse furrow that partly is pushed into the rear end of guiding line of rabbet joint 49a from the vertical direction at the rear portion of inducing ditch 43d of untie-sell 24a of connecting rod 24, shown in Figure 41 (D), connecting rod 24 is return a little towards the direction opposite with lead, and make loading arm 22 swing a little, and then finish the support of this loading roller 22a to the outer rim of major diameter disc D1 towards centrifugal direction.
In addition, with its simultaneously, the 1st oscillating structural member 45 carry out little play from untie-sell 45a at the rake of the meta of the vertical component effect 43b-3 that is formed at guiding ditch 43b, this swing meeting is conveyed to toothed disc 59 via armite 54.Whereby, disc supporting arm 19 is swung a little towards centrifugal direction, and finishes the support of the outer rim of 19 pairs of major diameter discs of this disc supporting arm D1.
On the other hand, lower end horizontal part 43b-2 significantly upwards the pushing away of the guiding ditch 43b of loading slider 43 by the 2nd oscillating structural member 47 from untie-sell 47a.Whereby, effect pin 47b swings towards centrifugal direction, and driven sliding block 48 moves horizontally and utilizes end through hole 48b to draw the effect pin 51a of the 3rd oscillating structural member 51, so, except the 3rd oscillating structural member 51 carried out little play, simultaneously, effect sheet 48d upwards pushed away the roller 42c of lever arm 42.Whereby, retreat because the card of the lever arm 42 of the support member 27a of guid arm 27 institute butt ends tongue piece 42a, guid arm 27 is swung a little towards centrifugal direction, and finishes the support of the outer rim of 27 pairs of major diameter discs of this guid arm D1.
At this moment, the ends urged guid arm 29 of the guiding ditch 43c-1 of loading slider 43 from untie-sell 29d, and make guid arm 29 carry out little play.Whereby, the support member 29a of guid arm 29 is towards the location of the outer rim of centrifugal direction swing and end major diameter disc D1.In addition, utilization is carried out little play from the guid arm 35 that untie-sell 35b is linked to the guiding ditch 29c of guid arm 29, and the location that makes support member 35a also finish the outer rim of major diameter disc D1 towards the centrifugal direction swing.
In addition, enter the stroke of Figure 15 from Figure 14, driven sliding block 48 moves horizontally with retreating synchronously of loading slider 43, yet, the rake 43e-2 of 43 cam ditch 43e from untie-sell 7a from loading slider of crane 7 enters the high-order 43e-3 of portion, then enters the high-order 48c-3 of portion from the rake 48c-2 of the cam ditch 48c of driven sliding block 48 from untie-sell 7b.
The movement aspect of the crane 7 in this trip, rise because of rake 43e-2.48c-2 from untie-sell 7a.7b, crane 7 also rises thereupon, shown in Figure 37 (C), the gripper jaw 9a of clamping head 9 is connected to the center pit D1 a of major diameter disc D1 and this major diameter disc D1 is upwards pushed away, and the periphery of center pit D1a is connected to the protuberance 2b of box casket 2.
Behind the top of arrival rake 43e-2.48c-2, shown in Figure 37 (D), clamping head 9 embeds the center pit D1a of major diameter disc D1, finishes the clamping of gripper jaw 9a from untie-sell 7a.7b from aforesaid state, and major diameter disc D1 is fixed on the universal stage 10.Secondly, enter the high-order 43e-3.48c-3 of portion from untie-sell 7a.7b, crane 7 drops to the position shown in Figure 37 (E), and can carry out the driving of major diameter disc D1.
More than, be that the action form of each mechanism when moving into major diameter disc D1 at optical disc apparatus of the present invention 1 describes, when shifting out, the action form of opposite order when being each mechanism along with the preceding and then execution of loading slider 43 with above-mentioned immigration.That is, begin to carry out shifting out of major diameter disc D1 and loading slider 43 when beginning to advance, shown in Figure 38 (A)～(E), crane 7 rises earlier and drops to initial position again.Therebetween, shown in Figure 38 (C), clamping is removed pin 71 major diameter disc D1 is upwards pushed away, and removes the clamping of clamping head 9.
As mentioned above, in the stroke till the clamping of removing major diameter disc D1, disc supporting arm 19, loading arm 22 and guid arm 27 beginnings are moved towards heart direction, and become the state shown in Figure 14 of the outer rim that is supported in major diameter disc D1, thereafter, utilize disc supporting arm 19 to shift out major diameter disc D1, and its leading section is exposed just from the notch 3a of panel 3 stop towards the power of heart direction swing.
In addition, Figure 42 (A)～(F) is the continuous action form from untie-sell 24a.29d.45a.47a that produces because of retreating of loading slider 43.
Secondly, with reference to the planimetric map of Figure 23 to Figure 29, and corresponding aforesaid Figure 30 to ground plan shown in Figure 36, the action form when transferring minor diameter disc D2 at optical disc apparatus of the present invention describes.In addition, among Figure 23 to Figure 29, cam ditch 43e.48c reaches and should be presented in the figure from untie-sell 7a.7b is former, yet, for convenience of description, illustrate in order to understanding.
Figure 23 and Figure 30 wait the holding state that minor diameter disc D2 inserts from the notch 3a of panel 3, and each arm is in original state and static.At this moment, guid arm 25 is at the back side of bottom panel 6, the large-diameter portion 64a of roller 64 that is fixed on the roller support plate 62 of aforementioned axis backing pin 26 is the low level fairlead 65b that are connected to Fig. 8 and rack slide shown in Figure 30 65, and guid arm 25 stops at the position of the full swing position of centripetal direction towards centrifugal direction swing specified quantitative.
If the insertion of disc is waited in the full swing position that guid arm 25 stops at centripetal direction on the formation, when then minor diameter disc D2 being inserted near the device left side, minor diameter disc D2 can enter the left side of support member 25a and can't transfer minor diameter disc D2, in order to prevent said circumstances, so the insertion of disc is waited in the full swing position that makes guid arm 25 stop at centripetal direction towards the position of centrifugal direction swing specified quantitative.In addition, the holding state of Figure 23 and minor diameter disc D2 shown in Figure 30 is consistent with the holding state of Fig. 9 and major diameter disc D1 shown in Figure 16.
Secondly, guid arm 27 pushes away because its base end part is subjected to the bullet of draft helical spring 53, hold the support member 27a that acts on front end towards trying hard to keep of heart direction swing, yet, be still in the location because be linked to the 3rd oscillating structural member 51 of a backing pin 27b, because of this guid arm 27 keeps the static state shown in Figure 23 that is in.Because be installed in the function of the binding metal wire 52 performance retainers between the effect pin 51a of the 1st oscillating structural member 45 of stationary state and the 3rd oscillating structural member 51, so can stop the swing of the 3rd oscillating structural member 51.
Same, pass on disc supporting arm 19, guid arm 29, guid arm 35 and the loading arm 22 of power to keep static and be in state shown in Figure 23 along with moving of loading slider 43.In addition, under the guiding of the cam ditch 43e of loading slider 43, crane 7 be positioned at the 43e-1 of low level portion of this cam ditch 43e from untie-sell 7a, on the other hand, under the guiding of the cam ditch 48c of driven sliding block 48, crane 7 be positioned at the 48c-1 of low level portion of this cam ditch 48c from untie-sell 7b, so crane 7 is in the minimum state that drops to shown in Figure 37 (A).
Figure 24 and Figure 31 front that to be the operator insert minor diameter disc D2 and this minor diameter disc D2 from the notch 3a of panel 3 is connected to the state of the holder 21 of disc supporting arm 19.This time point insert minor diameter disc D2 and during the left of minor diameter disc D2 deflection Figure 24 from notch 3a, because the front end left side of minor diameter disc D2 can contact the support member 25a of guid arm 25 and be pushed back, can prevent that minor diameter disc D2 from coming off from transferring the path.
In addition, when the insertion of minor diameter disc D2 is operated, shown in Figure 43 (A), the support member 29a of the front end right side of minor diameter disc D2 pushing guid arm 29 and when centrifugal direction is swung, the grab 37a card of the locking bar that is still in the location 37 that the tongue piece 29b shown in the same figure (B) is not swung ends, at this moment, also can prevent that minor diameter disc D2 from coming off from transferring the path.That is, utilize the support member 25a of guid arm 25 and the support member 29a of guid arm 29 that minor diameter disc D2 is directed to device central authorities.
Figure 25 and Figure 32 are the states that the operator further inserts minor diameter disc D2 under above-mentioned state, under the pushing of minor diameter disc D2, disc supporting arm 19 is swung towards centrifugal direction, simultaneously, contact the sidepiece of minor diameter disc D2 with the support member 29a of the support member 25a of the guid arm 25 of the swing interlock of this disc supporting arm 19 and guid arm 29.Whereby, minor diameter disc D2 is in the state of 3 support of the holder 21 that obtains aforementioned support member 25a.29a and disc supporting arm 19.
In addition, the base portion of disc supporting arm 19 as fulcrum, rotates to the position of Figure 39 (B) from the position of Figure 39 (A) with rivet pin 20, and utilizes the switch activated section 59e of portion of toothed disc 59 to start limit switch 60.According to the signal from the limit switch 60 that utilizes the aforementioned switches startup section 59e of portion to be started, the electric current of low level voltage flows through loading motor 66.At this moment, the component F1a that the pushing of the support member 29a of guid arm 29 produced, and the effect that utilizes draft helical spring 63 of the support member 25a of guid arm 25 to push the component F1b that is produced big and be in active state, generation advances minor diameter disc D2 towards the immigration direction the F2 that makes a concerted effort, and utilize this loading motor 66 to begin to carry out automatic loading.
Figure 26 and Figure 33 utilize loading motor 66 to begin to carry out automatic loading and the state that moves into minor diameter disc D2.Loading slider 43 further retreats from the state of Figure 25, and then guid arm 29 enters the guiding ditch 43c-2 of loading slider 43 from untie-sell 29d.At this moment, utilize the rake guiding support member 29d of guiding ditch 43c-2 and move it this slant distance, continue to move into minor diameter disc D2 and support member 29a is rocked to the position shown in the figure.At this moment, guid arm 25 continues to move into minor diameter disc D2 and is rocked to the position shown in the figure also under the effect of draft helical spring 63.
