Description
The present invention relates to a kind of movement device that just can make first and second actuating members selectively, for example tooth bar or follower gear be moved by a driven wheel.When especially relating to a kind of and the sort of member action in making tooth bar and follower gear, can make the not movement device of braking movably of another member.
Above-mentioned movement device is used on the device such as the dress disc equipment of CD for example.Below, the confined state of the movement device on the dress disc equipment of CD is described with Figure 12-Figure 15.
Figure 12 is the stereographic map of the whole dress disc equipment of CD, Figure 13 is the carriage leader of dress disc equipment of explanation CD and the figure of regeneration sector brace table, Figure 14 is that the dress disc equipment of expression CD is in carriage and pulls out drawing in side sectional elevation state under, and Figure 15 is the drawing in side sectional elevation of dress disc equipment when installing disc record of representing CD.
Expression is in order to make CD regeneration in Figure 12, installs in the disc equipment body after putting CD on carriage 01.Packing into and pulling out of above-mentioned carriage 01 is to be undertaken by moving back and forth of carriage 01, for this carriage 01 is moved back and forth, as illustrated in fig. 13, formation forms the combination projection 05 that combines recess 02 combination with this in conjunction with recess 02 on tooth bar 06 below this carriage 01.Tooth bar 06 can reciprocatingly be bearing on the regeneration sector brace table 07.In Figure 13, be apart in conjunction with recess 02 with in conjunction with projection 05, but under the state of assembling, normally conjugate.Thereby, when the revolution by driven wheel 08 moves back and forth tooth bar 06, just move back and forth with the projection 05 conjugate carriage 01 that combines of tooth bar 06.
Like this, if drive tooth bar 06 with driven wheel 08, install to carriage 01 in the disc equipment body after, just can clamp CD by clamp 010 and rotating disk 011.In order to carry out such clamping, at the lower surface of the carriage leader 015 of guide bracket 01, form the projection 016 of chevron highlightedly downwards, on hypodontia gear 019, form the cam surface 018 that this projection 016 is moved up and down.This hypodontia gear 019 is driven by above-mentioned driven wheel 08.
As shown in figure 14, when carriage 01 was packed into, an end of carriage leader 015 and regeneration sector brace table 07 had been separated from each other by rotation axis 021 supporting, the other end mutually.From state shown in Figure 14, hypodontia gear 019 (with reference to Figure 13) is rotated, thereby make cam surface 018 displacement, just make immediately with projection 016 cam surface that joins 018 and move on the lower position shown in Figure 15 from higher part position shown in Figure 14, and, make the two the other end of carriage leader 015 and regeneration sector brace table 07 approaching mutually as illustrated in fig. 15, make the upper surface of the lower surface of carriage leader 015 and regeneration sector brace table 07 approaching.At this moment also make clamp 010 and rotating disk 011 closer to each other, thereby the CD that puts on carriage 01 is clamped.
Like this,, tooth bar 06 is moved, carriage 01 is drawn in, then, tooth bar 06 is stopped, making until the hypodontia gear 019 that is at this moment also stopping to change, thereby CD is clamped by the revolution of a driven wheel 08.Therefore,, must convert the tooth engagement of driven wheel 08 and tooth bar 06 to the tooth of hypodontia gear 019 engagement, perhaps carry out the conversion opposite with this under the occasion that makes tooth bar 06 action and make under the occasion of hypodontia gear 019 action.
And the structure that is used for carrying out this conversion was to form extremely complicated structure with members such as springs in the past.Promptly, be transformed into hypodontia gear 019 in the driving that driven wheel 08 is caused from tooth bar 06, perhaps be transformed under the occasion of tooth bar 06 from hypodontia gear 019 on the contrary, must the tooth bar 06 of throwing off with driven object or hypodontia gear 019 be positioned at driven wheel 08 out of mesh position on.And, in tooth bar 06 course of action, make hypodontia gear 019 remain on driven wheel 08 out of mesh position on, perhaps on the contrary in hypodontia gear 019 course of action tooth bar 06 remain on driven wheel 08 out of mesh position on.For this reason, assist this switching motion, tooth bar 06 or hypodontia gear 019 can be located with members such as springs.Its result increases the part number of the movement device of hypodontia gear 019 this follower gear and tooth bar 06 action, the assembly work amount is increased, and manufacturing cost is improved.Also because complex structure, thereby just break down easily, reliability also just descends.
The present invention makes for the shortcoming that overcomes above-mentioned prior art, its objective is provides driven wheel of a kind of usefulness just can make first and second actuating members, for example tooth bar and follower gear be changed, make its action simultaneously, and the part number of packages is reduced, manufacturing cost is reduced, and the movement device of reliability is arranged.
To achieve the above object, movement device of the present invention has driven wheel P and is moved or is turned round the first and second actuating member R, the H that drives with this driven wheel engagement selectively.For example can be used as first and second actuating members to tooth bar R or follower gear H.
And the above-mentioned tooth bar R that can move back and forth has and the tooth portion 2 of above-mentioned driven wheel engagement and the brake portion 5 that is provided with along the motion track of tooth bar R.
And the above-mentioned follower gear H that can rotate is the hypodontia gear, it have the toothless portion) 22 that forms continuously with the circular-arc tooth portion 21 of the tooth of driven wheel P engagement, with this tooth portion 21, selectively be arranged on above-mentioned tooth bar R on the bound fraction 32 that combines of brake portion 5.
And, under bound fraction 32 and situation that brake portion 5 combines, the toothless portion) 22 that makes follower gear H facing to driven wheel P setting tooth portion 21 and the bound fraction 32 of follower gear H.
Above-mentioned tooth bar R possesses the situation of joining part 6 in addition, and this joining part is arranged on the end of brake portion 5, has the abutted surface that forms on the direction of intersecting with above-mentioned tooth bar R moving direction simultaneously; In this case above-mentioned, bound fraction 32 is made into and can combines with the brake portion 15 on being arranged on tooth bar R, and also can join with above-mentioned joining part 6.
And the tooth portion 21 of follower gear H and bound fraction 32 be configured under bound fraction 32 and situation that brake portion 5 combines, the toothless portion) 22 that makes follower gear H and driven wheel P facing to, when above-mentioned bound fraction 32 and joining part 6 join, make follower gear H revolution, thereby make the tooth portion 21 and driven wheel P engagement of follower gear H.
Under the situation that tooth bar R is braked, the follower gear H that can rotate also has with the tooth portion 21 of the tooth of above-mentioned driven wheel P engagement and is the circular-arc brake portion 30 at center with the rotation axis of follower gear H.
And the tooth bar R that can move back and forth have can with the tooth portion 2 of the tooth engagement of above-mentioned driven wheel P and the bound fraction 10 that can combine with the brake portion 30 on being arranged on above-mentioned follower gear H.
And the tooth portion 2 of tooth bar R and bound fraction 10 are configured under bound fraction 10 and situation that brake portion 30 combines, the tooth portion 2 of tooth bar R not with the tooth engagement of driven wheel P.
The brake portion 5 of the tooth bar R that can move back and forth has the situation of joining part 6 in addition, this joining part be connected with an end of brake portion 5, join, make this follower gear H to rotate with the bound fraction 32 of follower gear H, thereby make the tooth portion 21 of follower gear H and above-mentioned driven wheel P engagement.
The brake portion 5 of the tooth bar R that can move back and forth has the situation of removing part 7 in addition, thereby to remove part be the tooth portion 21 that is connected with an end of brake portion 5, join, make this follower gear H to rotate to make follower gear H with the bound fraction 32 of follower gear H and the engagement releasing of above-mentioned driven wheel P for this.
Above, so-called " with a driven wheel; change tooth bar and follower gear on one side it is moved " is not limited to situation that tooth bar and follower gear are moved, and also comprise the member that singly makes a side and convert to from action and be failure to actuate, and the situation of never moving into action.
In the above-mentioned movement device that constitutes like that, when making driven wheel P revolution, tooth bar R just is driven.At this moment, if the bound fraction 32 of follower gear H is combined with the brake portion 5 of tooth bar R, the toothless portion) 22 of follower gear H is just facing to driven wheel P, and tooth portion 21 and the driven wheel P of follower gear H do not mesh.Then, because tooth bar R is in moving process, the brake portion 5 of linearity moves abreast with moving direction, thereby bound fraction 32 is unshift.Like this, follower gear H is hindered by brake portion 5 and can not rotate.As a result, in bound fraction 32 and time that brake portion 5 combines, the action of follower gear H is stopped.
The brake portion 5 of the tooth bar R that can move back and forth has the situation that possesses joining part 6 again, this joining part be connected with an end of brake portion 5, join with the bound fraction 32 of follower gear H, this follower gear H is rotated, thereby make the tooth portion 21 of follower gear H and above-mentioned driven wheel P engagement.In these cases, if bound fraction 32 is until an end of brake portion 5, with joining part 6 join ground displacement, immediately, displacement by this bound fraction 32 is rotated follower gear H, make the tooth portion 21 and driven wheel P engagement of follower gear H, then, make follower gear H begin to rotate by the effect of driven wheel P.
In addition, in the movement device that tooth bar R braking ground is constituted, when driven wheel P turns round, follower gear H is rotated.At this moment, if the bound fraction 10 of tooth bar R is combining with the brake portion 30 of follower gear H, the tooth portion 2 of tooth bar R does not just mesh with driven wheel P.And, because in follower gear H rotation process, circular-arc brake portion 30 moves on same circumference, does not make bound fraction 10 displacements.Thereby tooth bar R is pind down by brake portion 30 and can not move.As a result, in 30 conjugate times, the action of tooth bar R is stopped at bound fraction 10 and brake portion.
The brake portion 5 of the tooth bar R that can move back and forth possess in addition link to each other with the one end, join, make follower gear H to rotate with the bound fraction 32 of follower gear H, thereby make the tooth portion 21 of follower gear H and the occasion of the releasing part 7 of the engagement releasing of driven wheel P, under this occasion, when the releasing part 7 on the end of bound fraction 32 and brake portion 5 is joined the ground displacement, displacement by this bound fraction 32, follower gear H is rotated, thereby the engagement releasing of the tooth portion 21 of follower gear H with driven wheel P.

Below, first embodiment of movement device of the present invention is described with reference to accompanying drawing.
At first with Fig. 1 driven wheel P, tooth bar R and the follower gear H that constitutes movement device is described in order, this movement device is the dress disc equipment that is applicable to CD.
Fig. 1 is the part drawing of explanation movement device of the present invention.
Among Fig. 1, the driven wheel P shown in the right side is so-called pinion wheel, and it is turned round by the motor effect of not representing on the figure.
Secondly, shown in entreating in the drawings is the tooth bar R as actuating member that is integrally formed into synthetic resin, it is made into the rectangle that roughly is elongated, it inside one side upper surface, form the joint portion 1 that combines with the carriage do not represented on the figure highlightedly upward.And, on the side, right side of tooth bar R, setting the tooth portion 2 that forms a plurality of teeth of engagement with driven wheel P, also on the side of the front of this tooth portion 2, setting the toothless portion) 3 that does not form tooth.
And at the upper surface of tooth bar R, along tooth portion 2 elongated braking groove 5 is being set with extending, it is as the brake portion that follower gear H is braked.This braking groove 5 forms abreast with the direction that moves back and forth of tooth bar R, and braking first cam surface 6 that forms on the side end in front of groove 5 as contact portion, it has the surface of contact that direction is intersected that moves back and forth with tooth bar R, form in the inboard of this first cam surface 6 with its facing to conduct remove second cam surface 7 of part.
In face of first cam surface 6, also form circular-arc as bound fraction on the side, again the spring 12 that the synthetic resin that is integrally formed into tooth bar R is made is being set in conjunction with groove 10 fronts one side in conjunction with groove 10.
On the lower surface of tooth bar R, form the groove 13 of the elongated switch motion action usefulness that makes motor.
This plastic actuating member of follower gear H is so-called hypodontia gear, central part at it can be supported rotationally by rotation axis 25, and on the periphery of follower gear H, setting with driven wheel P form engagement a plurality of teeth tooth portion 21 and do not form the toothless portion) 22 of tooth.And form and make among the figure the long frame leader of expression not move up and down the cam surface 26 of usefulness being circular arc ground around the rotation axis 25, on the upper surface of follower gear H, this cam surface 26 from the flat 26a of specified altitude to sloping portion 26b and perforate 27 reduces gradually formation and in succession with perforate 27.Be arranged near the boundary of tooth portion 21 and toothless portion) 22 perforate 28 and be and be used for being absorbed in the end impact of elastic deformation and the tooth top when making it with driven wheel P and meshing to the inside that makes tooth portion 21.
On the lower surface of follower gear H, form the prominent bar 30 of circular-arc braking downwards highlightedly, it has with tooth bar R goes up the identical radius of the arc radius in conjunction with groove 10 that forms.Center of arc as the prominent bar 30 of this braking of brake portion is the centre of gyration of follower gear H, and the prominent bar 30 of braking is that the rotary track along follower gear is provided with.In addition, also on the lower surface of follower gear H, form pin 32 downwards highlightedly as bound fraction.
Below, the action of movement device is described.
The action of the movement device of said structure is described with Fig. 2-Fig. 7.
Fig. 2 is the planimetric map of dress disc equipment movement device when carriage is pulled out state of CD, Fig. 3 is the planimetric map of movement device when becoming carriage and packing state into, Fig. 4 is driven wheel P from the movement device planimetric map of state shown in Figure 3 when turning round slightly, Fig. 5 clamps CD and the movement device planimetric map when installing disc record, Fig. 6 is the planimetric map of the clamping of CD movement device when beginning to remove, and Fig. 7 is the planimetric map of the movement device when carriage is begun to pull out.
Just become Fig. 2-state shown in Figure 7 if driven wheel P shown in Figure 1, tooth bar R and follower gear H be assembled together.
In Fig. 2-Fig. 7, follower gear H is configured on the position that its tooth can be meshed with the tooth of driven wheel P, and is positioned at the top of tooth bar R.That part of of tooth bar R that is positioned at follower gear H below all will dot by formal drawing method, but overlapped just not clear the knowing clearly of dotted line, and therefore, tooth bar R comprises and is in that part of of follower gear H below, is represented with state shown in Figure 1 entirely.
When the carriage of expression was not pulled out state in figure, movement device was in state shown in Figure 2.Among Fig. 2, the tooth of the tooth of driven wheel P and tooth bar R is meshing.In addition, the pin 32 of the bound fraction of follower gear H is combining with the braking groove 5 of tooth bar R.In this state, the toothless portion) 22 of follower gear H and driven wheel P are not driven gear P facing to, follower gear H and drive.
Entering from state shown in Figure 2 under the occasion that carriage is packed into, by on the figure not the drive motor of expression make driven wheel P revolution of the clockwise direction shown in the arrow in the figure, even towards the medial movement shown in the arrow, make with the conjugate joint portion 1 of carriage and also inwards move with the tooth bar R that is meshing with driven wheel P.
At this moment, the braking groove 5 of tooth bar R moves towards the direction of arrow to the inside with tooth bar R, but because braking groove 5 is to form abreast with the direction that moves back and forth of tooth bar R as described above, while thereby braking groove 5 on pin 32, slide and move, also just can not make pin 32 transversal displacements.Therefore, the pin 32 of follower gear H can not be moved by braking groove 5 location of tooth bar R, and follower gear H can not be that the center is turned round with revolving shaft 25 just.And at this moment, the toothless portion) 22 of follower gear H and driven wheel P can not make follower gear H action facing to, driven wheel P.
Before the toothless portion) 3 of tooth bar R was about to arrive the position of driven wheel P, first cam surface 6 joined with the pin 32 of follower gear H, makes pin 32 towards the left side displacement, thereby makes follower gear H begin to be the center, to turn round towards counter-clockwise direction with revolving shaft 25.At this moment state is in the intrinsic state of dress disc equipment that just in time is loaded into CD with the joint portion 1 conjugate carriage (not shown) of tooth bar R as shown in Figure 3.
As described above, at the pin 32 of follower gear H by first cam surface, 6 effects of tooth bar R towards the left side displacement, making follower gear H is the center after the counter-clockwise direction revolution with revolving shaft 25 shown in arrow among the figure, even again with the tooth portion 21 of follower gear H and driven wheel P facing to, beginning tooth engagement with driven wheel P.And the front end of the prominent bar 30 of the braking of follower gear H and tooth bar R to combine groove 10 approaching.
When driven wheel P is turned round slightly again, follower gear H is turned round a little, thereby form state shown in Figure 4.That is, when driven wheel P is turned round slightly, braked pushing of prominent bar 30 ends in conjunction with the end of groove 10, tooth bar R is inwards moved, its tooth portion 2 is separated with driven wheel P fully.As a result, face under the state of driven wheel P, at its toothless portion) 2 because of tooth bar R so tooth bar R can not be driven.And follower gear H since its tooth portion 21 facing to driven wheel P, their tooth is meshing, thereby follower gear H is driven gear P and drives, with revolving shaft 25 be the center, the counter-clockwise direction revolution shown in the arrow in the figure.Immediately, the prominent bar 30 of the braking of follower gear H begins to enter in conjunction with groove 10.Like this, can not be to a side displacement in front, so tooth bar R just can not be to a side displacement in front in conjunction with groove 10 because of braking prominent bar 30 obstructions.As a result, the tooth portion 2 of tooth bar R just can not mesh with the tooth of driven wheel P.
In Fig. 4, when follower gear H is further turned round, with similarly above-mentioned, tooth bar R since its toothless portion) 3 and driven wheel P facing to, thereby tooth bar R does not move.And follower gear H because of tooth portion 21 and driven wheel P facing to, their tooth is meshing, so follower gear H is driven, is the center, turns round towards the direction shown in the figure upward arrow with revolving shaft 25 by driven wheel P counter-clockwisely.The prominent bar 30 of the braking of follower gear H moves to slidably in conjunction with in the groove 10.Like this, with similarly above-mentioned, braked prominent bar 30 obstructions and can not make tooth bar R not to a side and inboard displacement in front to a side and inboard displacement in front in conjunction with groove 10.
Turn over about 3/4 circle at the pin 22 of follower gear H, when joining with the spring 12 of tooth bar R, on the figure not the switch of motor of expression be cut off, driven wheel P and follower gear H turned round with the inertia of the motor of not representing on the figure, pin 32 makes spring 12 distortion, forms state shown in Figure 5.Before this, the tooth portion 21 of follower gear H still with driven wheel P facing to, the toothless portion) 22 of follower gear H and driven wheel P are faced.Like this, even make driven wheel P revolution again, can not make follower gear H revolution by the inertia of motor.
When follower gear H is rotated, the cam surface 26 that forms on follower gear H also rotates, thereby make the part that combines with the carriage leader of scheming go up not have expression from flat 26a, move to perforate 27, carry out the clamping of CD by sloping portion 26b.
Then, when the motor revolution that is caused by inertia stops, by the elastic force of the spring 12 of tooth bar R pin 32 bullets of follower gear H to left, making follower gear H specifically is that rotate toward the clockwise direction a little at the center with revolving shaft 25, and makes the tooth portion 21 of follower gear H become the state that can be meshed with the tooth of driven wheel P.Thus, the disc record of CD is installed.
Then, under the occasion that CD is drawn off, on the contrary the clamping of CD is removed, pulled out carriage with above-mentioned dress disc record action.Because the action of the dress disc record that this action is made peace above-mentioned greatly is opposite, thereby only it is made simple explanation.
For CD is drawn off, under state shown in Figure 5, by on the figure not the revolution of motor of expression driven wheel P is turned round towards counter-clockwise direction.Immediately, the tooth in the tooth portion 21 of follower gear H is meshed with driven wheel P, makes follower gear H begin to rotate toward the clockwise direction, and Fig. 6 represents state at this moment.When driven wheel P is further turned round along the counter-clockwise direction shown in the arrow from state shown in Figure 6, and making follower gear H along the clockwise direction shown in the arrow, when roughly turning round 3/4 circle, the pin 32 of follower gear H joins with first cam surface 6 of tooth bar R and is pressed to a side in front.Fig. 7 is representing this state.
Before pin 32 and first cam surface 6 join, the toothless portion) 3 of tooth bar R and driven wheel P facing to, but push first cam surface 6 when pin 32, make tooth bar R towards in face of during a side shifting, the tooth in the tooth portion 2 of tooth bar R meshes with driven wheel P.Therefore, pin 32 has the function of the tooth portion 2 that makes tooth bar R and the actuating section of driven wheel P engagement.
In Fig. 7, make driven wheel P further towards the counter-clockwise direction revolution, make the tooth bar R that is meshing with driven wheel P towards moving in front, along with moving, second cam surface 7 of tooth bar R joins with pin 32, makes pin 32 displacement to the right, and directs into 5 li of braking grooves.Follower gear H is further turned round toward the clockwise direction thus, and its toothless portion) 22 and driven wheel P are faced, and the tooth in the tooth portion 21 of follower gear H is not meshed with driven wheel P.Then, get back to state shown in Figure 1.Finish to draw off action thus.
As mentioned above and since the prominent bar of the braking of the braking groove 10 of tooth bar R and follower gear H 30 the two all be made into circular-arcly, thereby tooth bar R can be pind down because of the combination in conjunction with groove 10 and the prominent bar 30 of braking on any one direction that moves back and forth.Pin 32 owing to follower gear H combines with the braking groove 5 of tooth bar R again, thereby the revolution of follower gear H is subjected to this in conjunction with obstruction.
In addition, because when installing the disc record of CD, on figure not the motor of expression cut that constantly, the toothless portion) 22 of driven wheel P and follower gear H facing to, even thereby make driven wheel P revolution by the inertia of motor, follower gear H does not do useless rotation yet.At this moment, the pin 32 of follower gear H makes spring 12 distortion of tooth bar R again.At the quarter at that time that motor stops fully, the elastic force by this distortion spring 12 rotates follower gear H slightly, can make follower gear H and driven wheel P form the state of engagement once more.
And, even do not use member such as spring, when tooth bar R and driven wheel P are meshing, because the effect of tooth bar R, also can stablize, reliably positively follower gear H remain on the out of mesh position of driven wheel P on.On the contrary, when follower gear H and driven wheel P are meshing, because the effect of follower gear H, can stablize, infallible tooth bar R remain on the out of mesh position of driven wheel P on.
And, join with pin 32 by first cam surface 6, can make to be in not tooth bar R of engagement (follower gear H) and driven wheel P engagement.After this, by joining of second cam surface 7 and pin 32, follower gear H is turned on the position that breaks away from driven wheel P fully always.That is to say,, tooth bar R is moved on the position that breaks away from driven wheel P fully always by the end of the prominent bar 30 of braking with in conjunction with the joining of the end of groove 10.
In addition, since only be arranged on function part on tooth bar R and the follower gear H ( cam surface 6,7 and sell 32, the prominent bar 30 of braking and in conjunction with groove 10) just can be changed the power that transmits by driven wheel P, thereby structure is simply, also not have the not normal of actuation time.
Below, second embodiment of movement device of the present invention is described with Fig. 8.
Fig. 8 is the planimetric map of second embodiment of movement device of the present invention.
In a second embodiment, first and second actuating members the two be respectively follower gear H
1, H
2, this point and the above embodiments have bigger difference.
And, follower gear H
1Shape make roughly identically with follower gear H, its tooth portion 41 is equivalent to that tooth portion 21, toothless portion) 42 are equivalent to toothless portion) 22, rotation axis 43 is equivalent to rotation axis 25, the prominent bar 45 of braking is equivalent to brake prominent bar 30, in addition, pin 46 is equivalent to pin 32.
In addition, be arranged on follower gear H
1The follower gear H of below
2 Tooth portion 51 is being set, toothless portion) 52 is consistent with follower gear H with rotation axis 53 this point, but on its upper surface, form braking groove 55 and brake darker different with follower gear H of groove 55 than this in conjunction with groove 60 this point.
It is the circular-arc of center that above-mentioned braking groove 55 is made with rotation axis 53, along follower gear H
2Rotary track and be provided with, with follower gear H
1Pin 46 combination selectively.And its end is at follower gear H
2The side face upper shed relax, and form as first cam surface 56 of joining part and with its facing to conduct remove second cam surface 57 of part.
In addition, in conjunction with groove 60 be selectively with follower gear H
