First embodiment of apparatus for replaying disc of the present invention at first, is described referring to figs. 1 through Fig. 7.
Fig. 1 is for example as the skeleton view of mechanism's part of the apparatus for replaying disc of vehicle mounted, Fig. 2 to Fig. 4 (A) is the vertical view that omits under the state of main case, Fig. 4 (B) is local amplification plan view, Fig. 5 (A) is a partial sectional view (B), Fig. 6 is a right side view, and Fig. 7 is used for the turntable of this device and the cut-open view of clamper.
Main case about 1 has the side plate 2 (side plate on right side only draws) of downward bending, is fixing auxiliary casing 3 (seeing Fig. 1, Fig. 5) between this left side plate.Motor 4 is fixed in the lower face side of auxiliary casing 3, and the turntable 5 that is disposed at the upper surface side of auxiliary casing 3 is installed on the turning axle of motor 4.In addition, the signal pickup 7 that the information that is recorded in the dish 6 is reset is installed also on auxiliary casing 3, under a part that makes dish 6 is exposed state outside the device, carries out the playback (Fig. 4 (A)) of recorded information by signal pickup 7.
At the outside surface of main case right plate 2, can ejection member 8 be installed free to advance or retreatly along fore-and-aft direction, by the extension spring 9 that is erected between ejection member 8 and the right plate 2, ejection member 8 is applied the involution power in indicator device the place ahead.Ejection member 8 has the bending small pieces 8a that bending to the inside forms, and has outstanding upward cam pin 10 simultaneously and in conjunction with projection 11 (Fig. 1, Fig. 4 (B), Fig. 6).
At the leading section of described main case 1, fixing to be provided with and inserting the synthetic resin member 13 (Fig. 1) that mouth 12 is extracted in the dish insertion of extracting out out coiling 6.Insert extraction mouth 12 and be positioned at the height and position lower slightly than main case 1, the above-below direction size of its left and right end portions is to match with the gauge that coils 6, but strengthens the above-below direction size at center section, makes the insertion of dish 6 easier.
At the upper surface of described main case 1, pair of right and left dish guides 14 is installed.Two guidess 14 are symmetrical L shaped shape, each sweep through fulcrum 15, can horizontally rotate the left and right end portions that is installed on main case 1 front end freely.And two guidess 14 mutually combine on one side end separately, make it to have mutual interaction relation.In addition, the another side of each guides lets droop, and is provided with in the inboard of the portion that respectively hangs down at the lower face side of main case 1 gathering sill 16 (Fig. 5) opposite each other.These gathering sills 16 are chimeric with the periphery of dish 6, and the size of its height and position and above-below direction and described insertion are extracted the height and position and the above-below direction size of the left and right end portions of mouth 12 out and coincide.And, apply the gathering sill 16 that makes each other rotating force towards detaching direction by 17 pairs of two dish guidess 14 of spring.
At the another side of described dish guides 14, clamper support plate 18 is that fulcrum, energy along continuous straight runs and above-below direction rotation are installed with freely with fulcrum 19.Each clamper support plate 18 has downward-sloping oblique plate 20, forms the combined hole 21 (Fig. 5) corresponding with each oblique plate 20 on main case 1.Thereby when resetting action, as Fig. 5 (B), two clamper support plates 18 separate to the left and right, make each oblique plate 20 deep insertion in the combined hole 21.
When two dish guidess 14 when each other gathering sill 16 approaching directions are rotated, the rotation one side two clamper support plates 18 inner edge ground that make each oblique plate 20 sliding contact combined hole 21 closer to each other on one side make progress.So as shown in Figure 2, when two gathering sills 16 are close to when parallel to each other, the oblique plate 20 of each clamper support plate 18 is deviate from from combined hole 21 as Fig. 5 (A), becomes with the upper surface of main case 1 to contact.
In the upper surface side of turntable 5, as shown in Figure 7, formation dish maintenance face 23.And be, will coil 6 be placed on this dish maintenance face 23 on and axially located.Dish maintenance face 23 be contained in formation annular recessed portion 24 between cylindric protruding 33 on the turning axle of motor 4.Cylindric protruding 33 upper end is in and dish maintenance face 23 substantially on the same plane, and is outstanding unlike dish maintenance face 23 at least.The most peripheral position of turntable upper surface promptly around dish maintenance face 23, forms the spigot surface 25 of taper, imbeds circular magnetic (iron plate etc.) 26 in the scope of dish maintenance face 23.
On the other hand, the press section 27 that forms on the clamper 22 usefulness lower surfaces remains on dish 6 on the dish maintenance face 23.In addition, the central part at clamper 22 forms teat 28 cylindraceous.Between press section 27 and teat 28, burying circular permanent magnet 29 underground.At the front end of described teat 28, form taper spigot surface 30,31 within it on all sides and the outer circumferential side respectively.On the inner peripheral surface of this external described teat 28, be connected with the spigot surface 30 of inboard and form cylinder inner peripheral surface 32, make cylinder inner peripheral surface 32 chimeric, realize turntable 5 and 22 pairs of centers of clamper with the outer peripheral face of projection 33.
In addition, on the periphery of described teat 28, also be connected and form cylinder outer peripheral face 34, make this cylinder outer peripheral face 34 chimeric, to forbid coiling moving of 6 in-plane with the center pit of dish 6 with the spigot surface 31 in the outside.
At the right side of main case 1 upper surface, as Fig. 1 to Fig. 4 (A), be that the center can be rotated control member 35 is installed freely with fulcrum 36.Control member 35 is sandwiched between the another side of the described cam pin 10 that is fixed on the ejection member 8 and right-hand dish guides 14, has and cam pin 10 contacted cam surfaces at right flank.In addition, on fulcrum 36, can rotate and adorn laminated spring 39 freely, this laminated spring 39 is between the another side of control member 35 and right-hand dish guides 14.
In addition, as shown in Figure 4, in be stretched spring 9 traction and during of ejection member 8 to the involution of device the place ahead, the paddy portion of cam pin 10 contact cam surfaces 37, elastic force by spring 17 separates two dish guidess 14, but as shown in Figure 2, when ejection member 8 is in when being pressed into the position, the peak portion of cam pin 10 contact cam surfaces 37, laminated spring 39 is pressed at full tilt on the another side outside surface of right-hand dish guides 14, overcome the effect of spring 17 and make two dish guidess 14 approaching, and make two gathering sills, 16 keeping parallelism states.
On described auxiliary casing 3, can be that the center is rotated and dish to be installed freely to be pushed back member 40 with fulcrum 41, push back member 40 by described ejection member 8, clamper support 18, control member 35 and dish and constitute control gear.This control gear is the actuation time of console panel guides 14 and clamper 22.
Dish pushes back member 40 has contact plug 42 at pivoting end, applies the elastic force that 6 courts of the dish on the turntable 5 is pushed back direction by contact plug 42 by spring 43.Push back member 40 locking plate 44 is arranged near center of rotation.This locking plate 44, as shown in Figure 4, in be stretched spring 9 traction and during of ejection member 8 to the involution of device the place ahead, make the end face 45 that forms on the ejection member 8 in conjunction with projection 11 contact locking plates 44, overcome the effect of spring 43 and make push back member 40 remain on after the rotation toward moving position, but as shown in Figure 2, when ejection member 8 is in toward moving position, the medial surface 46 of locking plate 44 with contact in conjunction with projection 11, ejection member 8 is remained in pushes the position.Near the center of rotation that pushes back member 40, also form contact site 47.
Moreover, when from insert extracting mouthful 12 insertions out when coiling 6, push back on the periphery that member 40 is pressed in dish 6, from the position of Fig. 2 to the position of Fig. 3 toward moving, this moment locking plate 44 medial surface 46 with combine projection 11 sliding contacts.Medial surface 46 is from throwing off in conjunction with projection 11 then, is stretched spring 9 tractions and the stage of involution contact with the end face 45 of locking plate 44 in conjunction with projection 11 at ejection member 8, pushes back further rotation a little of member 40 whereby, makes contact plug 42 from coiling 6 periphery separation.
Under the occasion in described main case 1 is installed in the main body of replay device,, install by padded coaming in order to protect to exempt from external vibration.Even if under this occasion, turntable 5 axial location of the all-moving surface of dish 6 relatively can not coil 6 all-moving surface relatively yet and change.
Next explanation has the action of the apparatus for replaying disc of said structure.
Before the insertion dish, as shown in Figure 1, ejection member 8 is remained on by the locking plate 44 that pushes back member 40 and pushes the position.And the cam pin 10 of ejection member 8 contacts with the peak portion of the cam surface 37 of control member 35, makes a pair of dish guides 14 approaching, and two gathering sills 16 are held in parastate.At this moment clamper 22 pivoting end by two clamper support plates 18 as Fig. 5 (A) lifts, and separates from turntable 5.
Under this state, coiled 6 o'clock from inserting extraction mouthful 12 insertions, dish 6 outer peripheral edges portion with about the gathering sill 16 of dish guides 14 combine, dish 6 keeps face 23 to move abreast substantially with described dish, pushing away the contact plug 42 that pushes back member 40 by dish 6 periphery as shown in Figure 2, overcoming the effect of spring 43 and make and push back member 40 toward moving.
Then, as shown in Figure 3, when dish 6 being inserted into dish 6 center teats 28 consistent substantially with the center of turntable 5, clamper 22 can be embedded in the position of coiling in 6 the center pit time, when promptly being inserted into the position that can remain on the rotating disk 5, at the locking plate 44 that pushes back member 40 the breaking away from of ejection member 8 in conjunction with projection 11, the contact site 47 that pushes back member 40 contacts with ejection member 8, forbids coiling 6 further push immediately.So, by locking plate 44 from throwing off in conjunction with projection 11, ejection member 8 is subjected to extension spring 9 tractions and double action, as Fig. 4 (B), end face 45 sliding contacts of the bending small pieces 8a of ejection member 8 and locking plate 44, make to push back member 40, contact plug 42 is separated from coiling 6 periphery further a little toward moving.Push back the involution that forms by spring 43 of member 40, forbidden with contacting of end face 45 by bending small pieces 8a.In addition, motor 4 and signal pickup 7 start explicitly with the double action of ejection member 8.
Because along with the involution of ejection member 8, cam pin 10 is divided a word with a hyphen at the end of a line to paddy portion from the peak portion of the cam surface 37 of control member 35, so two dish guidess 14 rotate by the direction that spring 17 separates towards each other, two gathering sills 16 separate from coiling 6.At this moment, because one side separated from one another decline on one side of the rotation end of two clamper support plates 18, so the clamper of being supported by two rotation ends 22 is equipped on the dish 6.So by means of permanent magnet 29 and magnetic 26 attractive force each other, the dish that dish 6 is held in turntable 5 keeps on the face 23.Under this state, the barrel surface each other 33,32 by recess 24 and teat 28 chimeric, the centering gains in depth of comprehension of turntable 5 and clamper are with correct carrying out.In addition, because the front end of teat 28 is provided with taper spigot surface 30, so clamper 22 and turntable 5 is just easier to the center.
In addition and since the dish of turntable 5 keep face 23 around be provided with taper spigot surface 25, so when dish inserts, can easily be directed to dish 6 on the dish maintenance face 23.
Then, if in the playback mode shown in Fig. 4, push the operation of ejection member 8, motor 4 and signal pickup 7 are stopped.In addition, because cam pin 10 divides a word with a hyphen at the end of a line to peak portion from the paddy portion of the cam surface 37 of control member 35, so two dish guidess 14 are closer to each other and become parastate, two gathering sills 16 combine with the outer peripheral edges portion of coiling 6.And, when the bending small pieces 8a of ejection member 8 when the end face 45 that pushes back member 40 separates, push back member 40 and drawn and rotate by spring 43, push back with contact plug 42 and coil 6.As a result, because dish 6 is outstanding a lot of outside device from inserting extraction mouth 12, so can be at an easy rate its taking-up.
Above-mentioned device, because dish 6 along a pair of dish guides 14, moves substantially abreast with dish maintenance face 23, the axial location of turntable 5 all-moving surface of dish 6 relatively is constant, so there is no need to make in dish 6 and the turntable 5 any one to move vertically.And coil 6 filling and undertaken by being pushed into the most afterwards with handgrip dish 6, the taking-up of dish 6 is undertaken by the double action that dish pushes back member 40, so do not coil conveyer, can make simple in structure and miniaturization, can reduce manufacturing cost significantly.In addition, take out operation and make contact plug 42 that dish pushes back member 40 and 6 moments that contact of dish coiling, on coiling, produce braking effect, the rotation of dish is stopped immediately.
In above-mentioned first embodiment, if being formed by friction material with coiling the position that contacts of contact plug 42 then coiled taking-up and operated and make the braking effect when contact plug 42 and dish contact further to improve.In addition, the power with motor carries out without hand carries out also can to constitute the push operation of ejection member 8.
Below with reference to Fig. 8 to Figure 11 second embodiment is described.Though identical with described first embodiment is partly with identical label and omits detailed explanation, but structurally there is the very important point different with first embodiment, promptly dish being inserted the hour indicator guides is being pushed away by dish toward moving, dish is pushed back and supports that on the structure this point of clamper be different by the double action of coiling guides.
Fig. 8 is the skeleton view of mechanism's part of indicating panel replay device, and Fig. 9 and Figure 10 are the approximate vertical views of broken section, and Figure 11 is the general profile chart of seeing from right-hand.
Dish guides 50 is made circular shape, and there is the engagement groove 51 that combines with the outer peripheral edges portion of dish 6 inboard.Steady arm 52 can rotate the upper surface that is installed on auxiliary casing 3 freely through fulcrum 53.Fix coupling shaft 54 at the pivoting end of this steady arm 52, can rotate the central portion that is connecting described dish guides 50 freely on the axle 54.The shape of steady arm 52 has locking plate 56 and contact site 57 the spitting image of pushing back member 40 among first embodiment near center of rotation, applied towards the elastic force of double action direction by spring 58.
So, as shown in Figure 10, in be stretched spring 9 traction and during of ejection member 8 to the involution of device the place ahead, contacting with the end face 59 of locking plate 56 of ejection member 8 in conjunction with projection 11, overcome the effect of spring 58 and steady arm 52 and dish guides 50 are remained on toward moving position, but when ejection member 8 be in manually push toward moving position the time, the medial surface 60 of locking plate 56 contact in conjunction with projection 11 with ejection member 8, will be stopped at the past position of moving to ejection member 8.
Dish guides 50 leads the outside surface at its both ends on side plate 2 inside surfaces of main case 1, become the fore-and-aft direction to-and-fro movement freely along device.
The clamper support plate 63 of support clamper 22 can rotate along the vertical direction and be installed on freely on the auxiliary casing 3, and, apply downward rotating force by spring 64.In addition, fixing laminated spring 65 at the pivoting end of clamper support plate 63, laminated spring 65 is being supported clamper 22 thus.
Constitute control gear by described steady arm 52, ejection member 8 and clamper support plate 63.This control gear is the actuation time of console panel guides 14 and clamper 22.Clamper support plate 63 has downward-sloping oblique plate 67.This oblique plate 67 ejection member 8 when moving with this ejection member 8 combine projection 11 sliding contacts, the result, clamper support plate 63 will overcome the effect of spring 64 and upwards rotation.
Next action among second embodiment is described.
Before dish inserted, as shown in Figure 8, ejection member 8 was remained in toward moving position by the locking plate 56 of steady arm 52.And the pivoting end that clamper 22 is held device support plate 63 as shown in Figure 9 lifts, and separates from turntable 5.
Under this state, if from insert extracting mouthful 12 insertion dishes 6 out, 6 the outer peripheral edges portion of then coiling combines with the gathering sill 51 of dish guides 50, pushes dish 6 o'clock like this, make dish guides 50 overcome spring 58 effect and toward moving.
Then, when being inserted into dish 6 center when consistent substantially with the center of turntable 5, just from the throwing off in conjunction with projection 11 of ejection member 8, the while contact site 57 of steady arm 52 contacts with ejection member 8 locking plate 56 of steady arm 52, forbids that coiling 6 further pushes.Then, be stretched spring 9 traction and double action of ejection member 8.At this moment, end face 59 sliding contacts of the bending small pieces 8a of ejection member 8 and locking plate 56 make steady arm 52 further a little toward moving, and dish guides 50 is separated from coiling 6 periphery.The involution that is formed by spring 58 of dish guides 50 and steady arm 52 is by forbidding in conjunction with projection 11 of ejection member 8.
In addition, owing to the involution along with ejection member 8, break away from from oblique plate 67 in conjunction with projection 11, so clamper support plate 63 leans on the effect of spring 64 and rotates, clamper 22 remains on dish 5 on the turntable 5.
If then, then push away oblique plate 67 therewith relatedly, clamper 22 is separated from turntable 5 in conjunction with projection 11 by manually making ejection member 8 toward moving.In addition, throw off and steady arm 52 and the double action of dish guides 50 from locking plate, outside device, push back by 50 dishes 6 of dish guides by the effect of spring 57 in conjunction with projection 11.
In above structure, because the filling of dish 6 also is to be undertaken by being pushed into the most afterwards with handgrip dish 6, the taking-up of dish 6 is undertaken by the double action of dish guides 50, so do not coil conveyer.In addition, owing to constituted at dish guides 50 from coiling 6 when separating, clamper 22 remains on dish 6 on the turntable 5, is used for dish 6 detent mechanisms that remain on the turntable 5 so there is no need special the setting.Thereby, do not coil conveyer yet, make simple in structure and miniaturization, can reduce manufacturing cost significantly.In addition, make dish guides 50 and coiled for 6 moments that contact, on dish, produce braking effect, the rotation of dish is stopped immediately coiling the taking-up operation.
Next, with reference to Figure 12 the 3rd embodiment is described.This embodiment is the variation of the dish guides among second embodiment, and Figure 12 is the broken section approximate vertical view.Also be with identical label and omit detailed explanation in this embodiment on the part identical with aforementioned two embodiment.
Among the figure 70 by about the two dish guidess of cutting apart, cut apart guides 71 for two and can rotate on the coupling shaft 54 that is connected the pivoting end that is located at steady arm 52 freely, and, apply all the time rotating force by spring 72 towards closing direction.
So, will coil 6 be inserted on the turntable 5 after, involution along with ejection member 8, the rotation a little of steady arm 52 and make dish guides 70 from coiling 6 when separating, two extended ends 73 of cutting apart guides 71 are contacted with the back side panel 1a of main case 1, overcome the effect of spring 72 and make two to cut apart guides 71 and open.
If dish guides 70 is made, this spline structure then only makes coupling shaft move a little can be so that coil guides 70 from coiling 6 separation significantly.
Next, with reference to Figure 13 the 4th embodiment is described.This embodiment also is the variation of dish guides, and Figure 13 is the broken section approximate vertical view.Also be with identical label and omit detailed explanation in this embodiment on the part identical with aforementioned three embodiment.
Among the figure 80 by about the two dish guidess of cutting apart, cut apart guides 81 for two and can rotate on the coupling shaft 54 that is connected the pivoting end that is located at steady arm 52 freely.And, different with the 3rd embodiment, cut apart guides 81 by spring 82 to two and apply all the time the separately rotating force of direction.Though cutting apart guides 81, these make each autorotation end 83 contact and be kept closed with the left side plate 2 of main case 1, but after being inserted into dish 6 on the turntable 5, involution along with ejection member 8, steady arm 52 rotates a little and makes dish guides 80 from coiling 6 when separating, two rotation ends 83 of cutting apart guides 81 fall within the peristome 84 that forms on the left side plate 2 of main case 1, cut apart guides 81 for two and open by spring 82.
If dish guides 80 is made this structure, dish guides 80 is irrespectively separated significantly from coiling 6 with the amount of movement of coupling shaft 54.
If second, third with the 4th embodiment in the dish guides, forms by friction material with the position that contact of dish, then coil and take out operation and the braking effect that coils guides and coil when contacting can further be improved.In addition, the power with motor carries out without hand carries out also can to constitute the push operation of ejection member 8.
As mentioned above, apparatus for replaying disc of the present invention, with the dish guides that combines with the periphery of coiling, make the dish and the dish of turntable keep face to move abreast substantially, the all-moving surface of the axial location of turntable being made relative dish is constant, is most significant digit by turntable with described dish maintenance face, no matter during in the dish filling, or when dish takes out, all there is no need to make in dish and the turntable either party to move axially.Thereby, can make simple in structure and miniaturization, can reduce manufacturing cost significantly.
In addition, be to go into to the end to carry out because dish inserts with hand push, the taking-up of dish pushes back member by dish or the dish guides carries out, so do not coil conveyer.In addition,, dish guides and clamper are linked,, also do not drive the device of these mechanisms so also be not used for dish is remained on detent mechanism on the turntable because dish is directed on the turntable by the dish guides.Thereby can make simple in structure and miniaturization, can reduce manufacturing cost significantly.
