Triggering lever 9 by effect spring 10, is middle mind-set acting force counterclockwise with fulcrum 9c, and disk detects lever 12 and detects arm spring 13 by disk, is middle mind-set acting force counterclockwise with fulcrum 12c.Left side centering lever 11 is middle mind-set acting force counterclockwise by centering arm spring 14 with fulcrum hole 11c.By these springs 10,13,14, the state that enters in the 1d of disk installation region with engagement pin 9a, disk test pin 12a, disk register pin 11a keeps stable.In addition, right centering lever 8, the engagement pin 8b on the end of the opposition side by being located at disk register pin 8a is attached on the connecting hole 11b of left side centering lever 11.Therefore, right centering lever 8 by making the centering arm spring 14 of centering lever 11 in a left side to the counter clockwise direction effect, is middle mind-set clockwise direction acting force with fulcrum 8c.By this effect, the state that enters into 1d part in disk installation region with disk register pin 8a keeps stable.
If insert disk 100 from Fig. 2 and insertion mouth 5 shown in Figure 3 to the direction of arrow 5a, side drive is located near the switch 50 that inserts mouthfuls 5 the central authorities before disk 100 and rubber rollers 38 surface of contact, forms closure.Switch 50 for example is made of optical sensor.To motor 24 energisings, motor 24 rotations are rotated by the rotation driving rubber rollers 38 of motor 24 by these switch 50 closures.If further be pressed into disk 100, push the rubber rollers 38 of rotation downwards according to the thickness of disk 100 to inside.Therefore, disk 100 be clamped in guide rod 44 and rubber rollers 38 between, driven by direction to the arrow 5a of Fig. 3, this guide rod 44 is fixed on the clamp lever 43.
By driving the disk 100 that rubber rollers 38 moves, after the disk test pin 12a of the periphery of disk 100 and engagement pin 9a that triggers lever 9 and disk detection lever 12 joins, move to arrow 5a direction again.State when Fig. 4 represents that the periphery of disk 100 contacts with disk register pin 8a and 11a.
From the state of Fig. 3 to the process of the state transitions of Fig. 4, the disk of being pushed by disk 100 detects the disk test pin 12a of lever 12, around fulcrum 12c, rotates to the direction (clockwise direction) shown in the arrow 12r.By the rotation to arrow 12r direction of disk detection lever 12, equally also near the cam pin 12b the fulcrum 12c of arrow 12r direction rotary disk detection lever 12 breaks away from left detent 18.Fig. 4 represents this disengaged position.Disk detects lever 12, and the cam 15d by cam pin 12b enters into support substrate 15 can rotate to arrow 12r direction again.That is, disk detects lever 12 and forms the state that together rotates with left side centering lever 11 again.
In addition, from the state of Fig. 3 to the process of the state transitions of Fig. 4, the engagement pin 9a that triggers lever 9 is pushed to the periphery of disk 100, around fulcrum 9c, rotates to the direction (clockwise direction) shown in the arrow 9r, cam 9d breaks away from right detent 19.Therefore trigger lever 9 form can with the right side state that lever 8 together rotates again of feeling relieved.
By moving disk 100 to arrow 5a direction again, disk register pin 8a, 11a, engagement pin 9a, disk test pin 12a are pushed to the peripheral direction of disk 100 respectively, and the outside to disk installation region 1d forms state shown in Figure 5.Under this state, disk 100 stops to move, and is positioned on the disk installation site.At this moment, roll shaft 36 is by motor 24 rotations, but owing to transmit certain friction between roll shaft 36 and the rubber rollers 38, therefore, it is big that friction between disk 100 and the rubber rollers 38 becomes, thereby, the state that form that the rubber rollers 38 contact with the record surface of disk 100 is not rotated, slip is rotated between roll shaft 36 and the rubber rollers 38.
In addition, explain as the back, move clamper shown in Figure 2 46 by the direction to the turntable 47a of crossbeam 47, turntable 47a enters in the medium pore of disk 100, and disk 100 is installed.Then, by action described later, disk register pin 8a, 11a are by periphery separation, engagement pin 9a, the disk test pin 12a of disk 100, and Fig. 6 represents the state of this separation.Under this state, driving switch 51, motor 24 stops, and the installation of disk 100 finishes.
Below, with reference to the action of Fig. 7 A and B～Fig. 9 A and B detailed description triggering lever 9.Fig. 7 A represents to insert the position of the triggering lever 9 before the disk 100, and this position is identical with Fig. 3.In Fig. 7 A and B～Fig. 9 A and B, diagram triggers lever 9, frizzen 21 and cam lever 23, the relation of their mutual positions shown in the exploded perspective view of Fig. 2.Triggering lever 9, by effect spring 10 (Fig. 3), is center of rotation with fulcrum 9c, to the counter clockwise direction acting force.
Under the state of the Fig. 7 (A) that represents the state identical with Fig. 3, be positioned at the drive pin 9b of the right-hand member that triggers lever 9, enter in the 1st grooved cam 21c that is located on the frizzen 21.Frizzen 21, shown in Fig. 7 (B), by going up the effect spring 22 of a guide finger 21a acting force among guide finger 21a, the 21b of the frizzen 21 in set guide hole 20a, the 20b, become state to Fig. 7 A top acting force to being entrenched in support substrate 15 (Fig. 2). Guide hole 20a, 20b have the tilt guides 20c of moving direction (above-below direction among Fig. 7 A) inclination with respect to cam lever 23 and the guide part 20d of the left and right directions among Fig. 7 A.In Fig. 7 (B), to the upper end of tilt guides 20c acting force, form the state that keeps guide finger 21a, 21b by effect spring 22.
If from the state of Fig. 7 (A), push triggering lever 9 and right centering lever 8 to the periphery of the disk 100 that inserts, rotate to the direction of arrow 9r, disk 100 just moves to and disk register pin 8a, 11a position contacting, is state shown in Figure 4.Under the state of Fig. 4, the cam pin 9d that triggers lever 9 breaks away from right detent 19, triggers lever 9 and can further together rotate with right side centering lever 8.Therefore, triggering lever 9 and further pushed away by disk 100, is the center with fulcrum 9c, rotates to the direction of arrow 9r.In addition, be entrenched in to disk 100 and push away disk register pin 8a, be the fulcrum 9c of the triggering lever 9 among the axle 8d of the right side centering lever 8 that counterclockwise rotates of middle mind-set with fulcrum 8c, follow the rotation of right centering lever 8, move to arrow 8r direction.Trigger the rotation of lever 9 and moving of fulcrum 9c by this, the drive pin 9b that triggers lever 9 moves to grooved cam 21e from grooved cam 21c.
Fig. 8 A represents the state that this moves.Move by this, guide finger 21a, 21b shown in Fig. 8 B, overcome the acting force of effect spring 22, move from the upside down end of the tilt guides 20c of guide hole 20a, 20b, so frizzen 21 moves downwards.Fig. 8 A is identical with the state of Fig. 5, and expression disk 100 arrives the state of disk installation site.
To be called " initial stage is moved (the 1st example that moves) " by the frizzen 21 that forms to the variation of the state of Fig. 8 A from the state of Fig. 7 A to the moving of the below of Fig. 7 A and Fig. 8 A.Move by the initial stage, the end face 21j of frizzen 21 is fastened on the pin 23b of cam lever 23, and pushes it.Before moving at the initial stage of cam lever 23, as shown in figure 16, be in the tooth bar 23m that is located on the cam lever 23 not with the state of driving pinion 34a engagement, but move by the initial stage, as shown in figure 17, tooth bar 23m moves to the position engaged with driving pinion 34a.So owing to gear set 34,34a, 33,32,35 rotate by motor 24, so cam lever 23 is driven by motor 24 via tooth bar 23m, beginning is further moved to promptly opposite with the direction of insertion 5a of the disk direction of the direction shown in the arrow 23r.By cam lever 23 to arrow 23r direction should move (the 2nd example that moves), have motor 24, belt 26, worm screw belt wheel 27, worm screw B30, rotation axis 29, worm gear 31, worm screw A32, relay gear A35, hobbing machine 37, roll shaft 36, rubber rollers 38, and the driving mechanism of the 23n of angling hole portion clamp lever shown in Figure 2 43 is rotated to Figure 17, arrow 43r direction shown in Figure 180.Clamper 46 descends thus, and the turntable 47a (Fig. 2) of crossbeam 47 enters in the medium pore of disk 100, and disk 100 is installed.
In addition, if by drive motor 24, cam lever 23 moves to the direction of arrow 23r from the state shown in Fig. 8 A, the chimerism of the pin 21f of frizzen 21, to the state variation shown in Fig. 9 A,, arrive topmost 23e from Fig. 8 A by the rake 23d of the grooved cam 23a of an example of cam guiding.In this moving process, owing in rake 23d, sell the left side that 21f is pushed to Fig. 8 A and Fig. 9 A, so frizzen 21 moves to the direction of arrow 21r.Here, by from the state variation of Fig. 8 A to Fig. 9 A, guide finger 21a, 21b shown in Fig. 9 B, by the guide part 20d of guide hole 20a, 20b guiding, move to the left side of Fig. 8 A and Fig. 9 A.So the cam 21g as an example of cam part that is formed by Fig. 8 A of frizzen 21 and Fig. 9 A middle and upper part hypotenuse promotes the axle 8d of right centering lever 8 upward.Its result, because right centering lever 8 is that center of rotation is to counterclockwise rotating with fulcrum 8c, triggering lever 9 is that middle mind-set clockwise direction is rotated with the drive pin 9b that is entrenched in the grooved cam 21e, so the engagement pin 9a of front end becomes the state (Fig. 9 A and Fig. 6) that separates from the periphery of disk 100.
In addition, as shown in Figure 6, if right centering lever 8 is that center of rotation is rotated to counter clockwise direction with fulcrum 8c, the left side centering lever 11 that is attached on the right centering lever 8 by engagement pin 8b is that center of rotation is rotated to clockwise direction with fulcrum 11c.Thus, disk register pin 8a and 11a also become the state that separates from the periphery of disk 100.In addition, disk detects lever 12 and also rotates to clockwise direction, and disk detects the state that lever 12 is the periphery that breaks away from disk 100.After the action more than finishing, the installation of big footpath disk 100 finishes.In this process, move to arrow 23r direction by above-mentioned cam lever 23, and shown in Figure 16～18, be driven under state shown in Figure 180 with the switch 51 of cam lever 23, motor 24 stops.
In addition, in the present embodiment, constitute drive unit (cam lever drive unit) by tooth bar 23m, gear set 34a, 34,33,32, worm gear 31, rotation axis 29, worm screw B30, worm screw belt wheel 27, belt 26 and motor 24.But the present invention is not limited in above-mentioned formation, also can: in order to move cam lever 23 driving forces after (the 1st example that moves) to the initial stage, make the engagement pin 9a that triggers lever 9 break away from the periphery of disk 100, and cam lever 23 the 2nd moved.
In addition, driving mechanism also is not limited to above-mentioned formation, as long as make disk insert the decline of end back, the formation that disk can be installed on the disk installation site gets final product.
In addition, in the present invention, the so-called the 1st moves, be instigate cam lever 23 move to the driving force of described drive unit (cam lever drive unit) give cam lever 23 activation point, be cam lever 23 moving from non-activation point to activation point.

In the disk loading device of present embodiment, no matter insert disk 120 from which position of inserting mouth 5, disk 120 can both be positioned on the disk installation site.
Below, with reference to the action of Figure 10 explanation when the left part of inserting mouth is inserted disk 120.After Figure 10 is illustrated in and inserts disk 120, with the disk register pin 11a state of contact of left side centering lever 11.
In Figure 10, if being inserted in disk 120, the user inserts in the mouth 5, front side on lean against rubber rollers 38, similarly, 50 (Fig. 1) that close a switch, motor 24 begin rotation during with the described big footpath of insertion disk 100.Rotation by motor 24, rotate rubber rollers 38, if be pressed into disk 120 again, just the rubber rollers 38 of rotating and be fixed on guide pole 44 on the clamp lever 43 between clamp circle disk 120, direction to arrow 5a is inserted disk 120, enters in the disk loading device.Because the disk test pin 12a that disk 120 at first detects lever 12 with disk bumps and connects, and pushes it, what rotate to clockwise direction so disk detects lever 12, and cam pin 12b breaks away from left side centering lever 18.Then, disk 120 bumps with the left disk register pin 11a that feels relieved lever 11 and connects, and pushes it.Disk register pin 11a is pushed to disk 120, so that its clockwise direction to Figure 10 is rotated, but since the cam pin 9d of centering lever 8 in the right side that links by being installed in rotation on the triggering lever 9 on the 8d be formed on support substrate 15 on engaging of right detent 19 and locked, so disk 120 contacts with disk register pin 11a, move to right-hand simultaneously, and further inserted.
And disk 120 bumps with the register pin 9a that triggers lever 9 and connects, and pushes it, and it is rotated to arrow 9r direction.Thus, cam pin 9d breaks away from right detent 19, removes the locking of right centering lever 8.But, along with disk 120 moves to right-hand, removing disk 120 connects with the bumping of disk test pin 12a that disk detects lever 12, thereby, disk detects lever 12 and rotates to counter clockwise direction by the acting force that detects arm spring 13, and cam pin 12b also resets to the state that engages with left detent 18.Thereby left side centering lever 11 is locked, and 11a is motionless for the disk register pin.Thereby disk 120 is met motionless disk register pin 8a, stops to enter.At this moment, disk 120 is also met the disk register pin 11a in left side, as shown in figure 12, because disk 120 is run into 2 disk register pin 8a, 11a, so be positioned on the disk installation site.
Below, with reference to Figure 11, the operation when inserting mouthfuls 5 right side part and insert disk 120 is described.The disk 120 that inserts at first bumps with the disk register pin 8a of right side centering lever 8 and connects.Run into right detent 19 owing to trigger the cam pin 9d of lever 9, so disk register pin 8a is motionless.Therefore disk 120 contacts with disk register pin 8a, moves to the upper left side of Figure 11 simultaneously.If disk 120 bumps with engagement pin 9a and connects, advance while just push it, trigger lever 9 and rotate to arrow 9r direction, therefore, the cam pin 9d that triggers lever 9 breaks away from right detent 19.But because a left side that links centering lever 11 is locked, so as shown in figure 12, the disk register pin 11a that disk 120 is run into left side centering lever 11 stops, and is positioned.Same during promptly with insertion under the state of Figure 10, disk 120 is by disk register pin 8a and 11a location.
In described operation, no matter in which of Figure 10 and Figure 11, disk 120 is met disk register pin 8a and 11a, all forms final location, before being about to form the state of Figure 12, triggering lever 9 and rotates to arrow 9r direction.The action of this triggering lever 9 is described with reference to Figure 12～Figure 15.
At location path disk 120, when forming the state of Figure 12, trigger lever 9 and be the state shown in Figure 14 A.This state is that the state before the insertion of path disk 120 is the state that Fig. 7 A changes.From this Fig. 7 A to the process of the state variation of Figure 14 A, by triggering the rotation of lever 9, the drive pin 9b that triggers lever 9 moves to the inlet of grooved cam 21h from grooved cam 21c, pushes away frizzen 21 to the direction of arrow 23r.By this action, as shown in Figure 14B, guide finger 21a, 21b overcome the acting force of spring 22, move (the 1st example that moves) from the upside down end of the tilt guides 20c of guide hole 20a, 20b.Thus, shown in Figure 14 A, the end face 21j of frizzen 21 pushes away the pin 23b of cam lever 23 to arrow 23r direction, and cam lever 23 moved to the below initial stage of Figure 14 A.Its result, same during with described big footpath disk 100, before initial stage moves, as shown in figure 16, be in the tooth bar 23m that is located on the cam lever 23 not with the state of driving pinion 34a engagement, but after moving in the early stage, as shown in figure 17, the tooth bar 23m of cam lever 23 moves to the position engaged with driving pinion 34a.Because gear set 34a is driven by motor 24, so further to arrow 23r direction translating cam bar 23 (the 2nd example that moves).Its result, to the state variation shown in Figure 15 A, pin 21f is arrived topmost 23e by the rake 23d of grooved cam 23a guiding to cam lever 23 from the state shown in Figure 14 A.In this moving process, owing to promote 21f to the left by rake 23d, so frizzen 21 moves to arrow 21r direction.By from the state variation of Figure 14 A to Figure 15 A, guide finger 21a, 21b shown in Figure 15 B, by the guide part 20d of guide hole 20a, 20b guiding, move to the left side of Figure 15 B.Because by moving, the rake guiding drive pin 9b to grooved cam 21h by this dip plane,, rotates to clockwise direction as fulcrum with drive pin 9c, so engagement pin 9a also rotates to arrow 9r direction, shown in Figure 15 A, breaks away from the periphery of disk 120.The vertical view of Figure 13 represents that engagement pin 9a breaks away from the state of the periphery of disk 120.This moment, disk register pin 8a and 11a contacted with the periphery of disk 120.
Below, with reference to Figure 16～Figure 18, illustrate that disk register pin 8a and 11a break away from the action of the periphery of disk 120.
Figure 16～Figure 18 is the right side view of Figure 13.As shown in figure 17, disk register pin 8a has large-diameter portion 8m and the diameter minor diameter part 8n littler than large-diameter portion 8m.As concrete size, for example the diameter of large-diameter portion 8m is 3mm, and the diameter of minor diameter part 8n is 1mm.As Figure 10～shown in Figure 13, when positioning disc 120, ride over mode on the large-diameter portion 8m with the peripheral part of disk 120, set the height of disk 120 and disk register pin 8a and 11a.
In the insert action of Figure 12 and disk 120 shown in Figure 13, to the state shown in Figure 15 A, cam lever 23 moved to the direction initial stage of arrow 23r from the state shown in Figure 14 A.The result that 23 initial stages of cam lever move is, as previously mentioned, before moving as shown in figure 16, be in the tooth bar 23m that is located on the cam lever 23 not with the state of driving pinion 34a engagement, but as shown in figure 17, the tooth bar 23m of cam lever 23 and driving pinion 34a mesh.Because gear set 34,34a, 33,32,35 by belt 26, worm screw belt wheel 27, worm screw B30, rotation axis 29, and worm gear 31 rotated by the drive force of motor 24, so cam lever 23 is accepted the driving force of motor 24 via tooth bar 23m, further the direction to arrow 23r moves (the 2nd example that moves).By moving of this cam lever 23, the 23n of angling hole portion that roller gear 37 is arranged on the cam lever 23 guides, and as shown in figure 18, becomes the state that moves downwards.At this moment, because the engagement of relay gear A35 and roller gear 37 breaks away from, stop so being maintained at the rotation of the rubber rollers 38 on the roll shaft 36 that roller gear 37 is installed.The result that roller gear 37 moves is downwards supported from the below that by rubber rollers 38 clamp lever 43 is the center with axle 43a, rotates to the direction shown in the arrow 43r.Making leaf spring 45 on the clamp lever 43 of global shape shown in Figure 2 is installed thus to the motion of the direction shown in the arrow 45r, clamper 46 in its lower section is installed, push away disk 120 about 3mm to the direction shown in the arrow 45r (Figure 18).Its result, the hole of the central authorities of disk 120 embeds in the turntable 47a (Fig. 2 and Fig. 3).Press lower disc 120, the result, the periphery of disk 120 breaks away from large-diameter portion 8m, does not keep the predetermined gap subtend in contact with the inner peripheral surface of minor diameter part 8n.By above operation, the periphery of disk 120 breaks away from disk register pin 8a and 11a, the state that formation can be rotated.
In addition, about taking out the disk 100 of installation or 120 operation, omit explanation from disk loading device.
According to the present invention, when big footpath disk 100 is installed in disk loading device, be used for comprising of positioning disc 100 of right centering lever 8, trigger all inscapes that lever 9, left side centering lever 11 and disk detect lever 12, be positioned at the outside of the installation region 1d of disk 100, not on disk 100 on.So, can be from peristome 2a, the 2b of the auxiliary bracket 1 of Figure 1 and Figure 2, see disk 100 above.
When path disk 120 was installed, right centering lever 8 and left side centering lever 11 were positioned at installation region 1d, but separate from the periphery of path disk 120.Thereby, can be from described peristome 2a, 2b, see disk 120 above.Because the top of disk 100 and 120 no described organize factor, thus can make top and auxiliary bracket 1 between the interval be too narrow to disk 100 or 120 discontiguous degree in the rotation.Thus, thickness that can the attenuate disk loading device (can miniaturization).
In addition, the present invention is not limited to above-mentioned embodiment, can implement in other multiple mode.For example, in the present embodiment, right centering lever 8, triggering lever 9, left side centering lever 11 and disk detect lever 12, to support by axle separately, rotatable mobile mode constitutes, but these key elements also can constitute in the mode that moves (linear action) by slide mechanism or bindiny mechanism's isoline.
In addition, though with the right side feel relieved the engagement pin 8b of lever 8, the engagement pin 9a that triggers lever 9 and drive pin 9b, left side centering lever 11 connecting hole 11b, and the disk disk test pin 12a that detects lever 12 be located at the front end or the end of each lever respectively, but, the present invention is not limited thereto, so long as can bring into play the position of each function, can be located at the position arbitrarily in each lever.
The present invention can be used in can shared big footpath disk and the slim disk loading device of path disk in.
In addition, the embodiment arbitrarily by in the above-mentioned various embodiments of suitable combination can access the effect that has separately.
The present invention has fully put down in writing preferred embodiment with reference to accompanying drawing, but for the people that are familiar with this technology, can carry out various deformation or change.So distortion or change only otherwise break away from the scope of the present invention of the scope dictates of claims, all is interpreted as comprising in the present invention.
