Description
Technical field
The present invention relates to a kind of compact disc holder that is used to keep CD (CD), DVD CDs such as (digital versatile dish or digital video disks).More particularly, the present invention relates to a kind of use anchor clamps, the compact disc holder that CD is sandwiched between rotating disk, keeps.
Background technology
As the existing compact disc holder of being located on dvd playback (record) devices such as CD and DVD, use CD is remained on the anchor clamps that it is rotated.As shown in figure 15, anchor clamps 100 are disposed at the opposition side of rotating disk 102 across CD 101.The magnet 103 that is fixed on the anchor clamps 100 is adsorbed on the rotating disk 102 that is made of magnet, and by this, anchor clamps 100 and rotating disk 102 keep the central part of CDs 101.Again, when CD 101 was kept, the centering ring 104 of rotating disk 102 was embedded in the medium pore 101a of CD 101, and CD 101 is carried out centralized positioning.Have again, under the driving of the spindle drive motor 105 that rotating disk 102 is installed, make rotating disk 102 rotations.Along with the rotation of rotating disk 102, CD 101 also rotates with anchor clamps 100.
In addition, around anchor clamps 100, be provided with the jig arm 106 of disk player.Jig arm 106 can be sticked in the outer circumference portion of anchor clamps 100, and can move along above-below direction among Figure 15 under the driving of not shown drive unit.Leave the distance of rotating disk 102 when big when jig arm 106, anchor clamps 100 are hung by jig arm 106 and keep.Again, if jig arm 106 moves near the rotating disk 102, then anchor clamps 100 break away from the supporting of jig arm 106, are adsorbed in rotating disk 102.
But,, anchor clamps 100 must be kept out of the way to abundant position away from CD 101 and rotating disk 102 for insertion or the ejection that does not hinder CD 101.Therefore, for the device that is used for abundant mobile jig arm 106 also becomes greatly, can't realize the miniaturization of dvd playback (record) device and reduce cost.
The objective of the invention is to: a kind of like this compact disc holder is provided, and described compact disc holder does not need to be used for the device of mobile jig arm, can anchor clamps be adsorbed on the rotating disk, and CD is kept by simple structure.
For realizing this purpose, technical scheme 1 described compact disc holder is provided with: be used to place the also rotating disk of rotary CD; The anchor clamps that are adsorbed on the rotating disk and CD is kept; The jig arm of supporting fixture; Keep anchor clamps make its at least can with the clip position of rotating disk absorption, and break away from the retaining member that moves and have the reset force that is back to position of readiness between the position of readiness of rotating disk.Described retaining member is installed on the described jig arm by the spring with described reset force, and the reset force that retaining member had is less than the absorption affinity of anchor clamps and rotating disk.
Thus, leave when far away in rotating disk and anchor clamps relative distance, anchor clamps are positioned at the position of readiness that leaves rotating disk under the maintenance of the retaining member of the elastic force with spring.On the other hand, if rotating disk and anchor clamps are approaching, then because the absorption affinity of anchor clamps and rotating disk is back to the reset force of position of readiness greater than retaining member, so under the effect of this absorption affinity, retaining member moves to clip position, thus, anchor clamps are adsorbed on the rotating disk, and CD is kept.For example, by mobile rotating disk, can utilize itself and retaining member absorption affinity and with the absorption affinity of rotating disk, anchor clamps can be away from mobile between the position of readiness on the CD and the fixed position that keeps CD.Thus, do not need to install the device of mobile jig arm.
Again, in each described compact disc holder of technical scheme 1 to 4, retaining member has magnet, and above-mentioned retaining member and described anchor clamps are attached together.At this moment, retaining member can all be made of magnet, also can part be made of magnet.

Concrete embodiment
Followingly specify formation of the present invention according to illustrated example.
Fig. 1 to Fig. 5 is a kind of example of compact disc holder of the present invention.This compact disc holder is provided with: place the also rotating disk 3 of rotary CD 5; Be adsorbed on the rotating disk 3 and be used to keep the anchor clamps 1 of CD 5; The jig arm 2 of supporting fixture 1; Keep anchor clamps 1 to make it at least can be at retaining member 4 mobile and that have the reset force that is back to position of readiness 1a between the fixed position 1b that is adsorbed in rotating disk 3 and the position of readiness 1a that breaks away from rotating disk 3.The reset force of retaining member 4 is less than the absorption affinity of 3 of anchor clamps 1 and rotating disks.
For example: in the compact disc holder of this example, anchor clamps 1 are adsorbed on the retaining member 4 and are carried out maintenance.The absorption affinity that anchor clamps 1 and rotating disk are 3, the absorption affinity that reaches 4 of anchor clamps 1 and retaining members is the magnetic force that utilizes magnet set on the anchor clamps 18 to be produced.
In the compact disc holder of this example, the volute spring 17 of retaining member 4 by reset force is arranged is installed on the jig arm 2.Like this, the structure of retaining member 4 is: on being adsorbed in anchor clamps 1, give the elasticity that remains on position of readiness 1a confining force to anchor clamps 1.This elasticity confining force is less than the absorption affinity of 3 of anchor clamps 1 and rotating disks.
In this example, the right of getting among Fig. 1 and Fig. 2 is a vertical direction, below, for ease of explanation, direction is meant the last direction of vertical direction on the what is called, so-called direction down is meant the following direction of vertical direction.
Anchor clamps 1 are built in the disk player, and as shown in Figure 2, CD 5 is clipped between anchor clamps and the rotating disk 3 and is kept, that is, and clamping, and the CD 5 of clamping is turned round simultaneously with rotating disk 3.In this example, anchor clamps 1 are made of jig main body 6, magnet holder 7, magnet 8.Jig main body 6 is made of plastics with magnet holder 7.
The jig main body 6 of this example is cylindric, is respectively equipped with 2 groups of different flange parts at the two ends of this cylinder, 3 every group, that is: and 9a, 9a, 9a and 9b, 9b, 9b (with reference to Fig. 3).Bottom surface in jig main body 6 inside, the outstanding in the form of a ring magnet incorporating section that is provided with 10 is concentric with the magnet holder installation portion 11 that is higher than the increase of magnet incorporating section 10 and diameter.Magnet incorporating section 10 is provided with ringshaped magnet 8.On magnet holder installation portion 11, be provided with the pawl 12 that is used to install magnet holder 7.Become suborbiculate magnet holder 7 and pawl 12 engagements, and be installed on the jig main body 6, thereby the magnet 8 that is accommodated in the magnet incorporating section 10 is kept.Disc centre in magnet holder 7 is provided with towards the outstanding hemispherical teat 15 of jig main body 6 peristomes.Be provided with the hole of centering usefulness in the bottom center of jig main body 6, the bottom surface periphery in this hole bears a bearing portion 13 of spools 20 of rotating disk 3 when being provided with fixedly.
Around anchor clamps 1, but be provided with the jig arm 2 of free rotary ground supporting anchor clamps 1.Jig arm 2 in this example is fixed in the disk player.And the arm 2a of anchor clamps 1 engagement is positioned between flange part 9a and flange part 9b, and anchor clamps 1 can move in the scope between flange part 9a and flange part 9b.
Again, in this example, the arm of the arm 2a of jig arm 2 is thick in the CD direction of insertion attenuation gradually shown in the arrow A.That is: the face that forms with CD 5 subtends of arm 2a is parallel with CD 5, and its face back to CD 5 then tilts towards CD direction of insertion A.As hereinafter described, in this example, anchor clamps 1 and retaining member 4 are attached together when flat, even just in case anchor clamps 1 are freed with the absorption of retaining member 4, anchor clamps 1 vertically drop, at this moment, also can under the tractive of the arm 2a that flange part 9a tilts, make anchor clamps 1 be in the state (with reference to Fig. 5) that relative CD direction of insertion A tilts.By adopting this kind structure, even insert CD 5 under anchor clamps 1 and retaining member 4 absorption disengaged positions, CD 5 can not bump against on the anchor clamps 1 yet, can not occur that CD 5 can't insert or fault such as damage.
When retaining member 4 is flat and anchor clamps be attached together, make anchor clamps 1 be positioned at position of readiness 1a shown in Figure 1.The material of retaining member 4 is a magnet, preferably uses the stainless steel that surface working is smooth and be difficult for getting rusty.Retaining member 4 is attached together with the jut 15 of magnet holder 7 under the magnetic attraction of the magnet 8 that embeds anchor clamps 1.Contact the frictional resistance in the time of to reduce anchor clamps 1 rotation with the point of anchor clamps 1 by retaining member 4.
The both end sides of retaining member 4 is installed on the clip arm 2 with screw etc.To centre, be provided with the hole 13 that the insertion section 2b that yarn forms on the jig arm 2 can run through, move in roughly vertical (length) of retaining member 4 again.The volute spring 17 that is disposed at insertion section 2b remains on state with detent 14 butts by elastic force with retaining member 4.When retaining member 4 is connected on the detent 14, the flange part 9b and the arm 2a butt of the anchor clamps 1 that are attached together with retaining member 4.This state is the position of readiness 1a (with reference to Fig. 1) of anchor clamps 1.Retaining member 4 is a fulcrum with installation site 16 shown in Figure 1, and the elastic force that can overcome volute spring 17 rotates.
Rotating disk 3 is provided with discoid CD support plate 18 and embeds the medium pore of CD 5, the bourrelet 19 of feeling relieved, and is installed on the axle 20 of Spindle Motor (not shown), rotates under the driving of this motor.Post the rubber 26 of CD 5 slips that prevent to be placed on the CD support plate 18.Rotating disk 3 under the driving of not shown drive unit, the position of readiness 3a (with reference to Fig. 1) that breaks away from anchor clamps 1 and and the dvd playback position 3b (with reference to Fig. 2) that is attached together of anchor clamps 1 between move.Bourrelet 19 is provided with magnet 21 such as iron, and at dvd playback position 3b, under the magnetic force of the magnet 8 in embedding anchor clamps 1 used, anchor clamps 1 were attached together with rotating disk 3.
Here, 1 of retaining member 4 and anchor clamps are by absorption affinity that magnetic force the produced general assembly (TW) (that is: jig main body 6 amounts to the weight of magnet holder 7 and magnet 8) greater than anchor clamps 1.Therefore, the phenomenon that absorption that deadweight owing to anchor clamps 1 makes itself and retaining member 4 breaks away from can not take place.
As by retaining member 4, anchor clamps 1 being suspended in the power of position of readiness 1a again,---the elastic force of volute spring 17 is greater than the general assembly (TW) of anchor clamps 1.On the other hand, 1 absorption affinity that is produced by magnetic force of rotating disk 3 and anchor clamps is before rotating disk 3 close dvd playback position 3b, greater than the elastic force of volute spring 17.Therefore, when rotating disk 3 was positioned at position of readiness 3a, retaining member 4 was suspended in position of readiness 1a with anchor clamps 1, if when rotating disk 3 moves to dvd playback position 3b, retaining member 4 overcomes the elasticity confining force of volute spring 17 and rotates, and anchor clamps 1 are adsorbed on the rotating disk 3.
The following describes the action of the compact disc holder that adopts above-mentioned formation.Before playing CD 5, as shown in Figure 1, retaining member 4 is suspended in position of readiness 1a with anchor clamps 1, and rotating disk 3 also is positioned at the position of readiness 3a that breaks away from anchor clamps 1.That is: anchor clamps 1 have enough distances with rotating disk 3 relative positions, can be to mobile the cause obstacle of CD 5 to CD direction of insertion A.
When playing CD 5, if when CD direction of insertion A inserts CD 5 and arrives assigned positions, rotating disk 3, moves by direction shown in the arrow 8B towards dvd playback position 3b from position of readiness 3a.In moving process, CD 5 is placed on CD carries and hold on the plate 18, bourrelet 19 embeds the medium pore of CDs 5, and rotating disk 3 coincide with the central portion of CD 5.Before moving to dvd playback position 3b by rotating disk 3, anchor clamps 1 overcome the elastic force of volute spring 17 under the attraction of rotating disk 3, be adsorbed in (with reference to Fig. 2) on the rotating disk 3.
By this suction-operated, anchor clamps 1 are clamped CD 5 with rotating disk 3.At this moment, the axle 20 of rotating disk 3 contact with the bearing portion 13 of anchor clamps 1, and rotating disk 3 and anchor clamps 1 center are identical.Rotating disk 3 and CD 5 and anchor clamps 1 rotate under the driving of Spindle Motor under the center fits like a glove state.
Finish or end to play CD 5, rotating disk 3 moves to position of readiness 3a, and the anchor clamps 1 that are adsorbed on the rotating disk 3 move simultaneously with rotating disk 3.But on anchor clamps 1, flange part 9a hangs on the arm 2a, with the absorption disengaging of the rotating disk 3 that moves to position of readiness 3a.Like this, under the effect of the elasticity confining force of volute spring 17, retaining member 4 rotates, and anchor clamps 1 are winched to position of readiness 1a.Thus, anchor clamps 1 are got back to position of readiness 1a.
As mentioned above, the compact disc holder according to the present invention needn't mobile jig arm 2, can be between position of readiness 1a (with reference to Fig. 1) and clip position 1b (with reference to Fig. 2) mobile anchor clamps 1.Therefore, do not need the device of mobile jig arm 2, can obtain simple structure, small-sized and disk player cheaply.
Again, magnet 8 and 21 magnetic force that produced of magnetic (attractive force) are owing to magnetic---and the existence of retaining member 4 increases.Shown in Fig. 4 (A), during no retaining member 4, in the side of magnet 8 back to magnetic 21, the magnetic line of force is made open shape as shown in phantom in FIG..Shown in Fig. 4 (B), because magnetic---the existence of retaining member 4, the open magnetic line of force passes retaining member 4 and forms magnetic circuit.Like this, the flux density that magnet 8 and magnetic are 21 uprises, and it is big that magnetic force becomes.Do not have the magnet 8 that surpasses necessary magnetic force even do not use, because the existence of retaining member 4, the magnetic force that can obtain wishing (attractive force) yet.
Above-mentioned example only is one of most preferred embodiment of the present invention, and the present invention is not limited to this, without departing from the spirit and scope of the present invention various variations can be arranged.
For example, the shape of anchor clamps 1, and the shape of retaining member 4 is not limited only to above-mentioned example.Shape as jig main body 6a shown in Figure 6 and magnet holder 7a, magnet 8 also can make such structure: not across magnet holder 7a, but directly and retaining member 4 subtends and putting, in addition, jut 15 is made slowly outstanding shape, make magnet 8 close with the relative distance L of retaining member 4.By shortening relative distance L, anchor clamps 1 strengthen with the absorption affinity of retaining member 4.And for example shown in Fig. 4 (B), can further strengthen the absorption affinity of anchor clamps 1 and rotating disk 3.As the shape of retaining member 4a shown in Figure 7, can make such structure: by with by near the retaining member 4a part of fixing magnet 8 subtends of jig main body 6b and magnet holder 7b and the magnet 8a.In addition, as the shape of magnet 8a shown in Figure 8, can make such structure: be positioned near the retaining member 4 by the fixing magnet 8a of jig main body 6c and magnet holder 7c.Again,, can omit magnet holder 7 as the shape of jig main body 6d shown in Figure 9 and magnet 8b, only with jig main body 6d take in, holding magnet 8b.
In above-mentioned example, be provided with the teat 15 that contacts with retaining member 4 in magnet holder 7 sides, also can be roughly hemispheric teat 22 in retaining member 4 side settings as shown in figure 10.Have, anchor clamps 1 remain on the retaining member 4 by pivot again.For example, can make the part depression of jig main body 6e, but form the teat support 23 of free rotary ground supporting teat 22, constitute pivot by teat 22 and teat support 23.By this, anchor clamps 1 just can not deviate to radially (Figure 10 shown in the arrow C) of CD 5 from retaining member 4.Thus, can be when chucking optical disk 5, it is good that anchor clamps 1 and rotating disk 3 centers are coincide, and when playing CD 5, can prevent that the side direction of anchor clamps 1, rotating disk 3, CD 5 from beating (the CD 5 footpath direction vibrations that the gap of turning axle and bearing and CD 5 centre-of gravity shifts etc. cause) again.At this moment, shown in Figure 13 (A), the radius-of-curvature of the depression of teat support 23 can be done greater than the structure of teat 22.Like this, because the contact area of teat 22 and teat support 23 reduces the frictional resistance in the time of can reducing anchor clamps 1 revolution.In addition, shown in Figure 13 (B), the radius-of-curvature of the depressed part of teat support 23 can be done to such an extent that be slightly larger than the structure of teat 22.At this moment, can prevent conscientiously that anchor clamps 1 from departing to CD 5 radially from skew retaining member 4.
In addition, retaining member 4 is not limited in the above-mentioned example that all is made of magnetic, as shown in figure 11, can connect magnetics 24 such as stainless steel on the opposite of the teat 15 of the retaining member 4c that is made by synthetic resin etc.As shown in figure 12, also can connect magnetics 25 such as iron at the opposite side on teat 15 opposites of the retaining member 4d that makes by synthetic resin etc. again.By configuration magnetic 25 on the opposite of teat 15 and opposite sides,,, also needn't select this type of material, so help to reduce manufacturing cost so will surface working do not get very smoothly because magnetic 25 does not directly contact teat 15.
Also can use leaf spring as retaining member 4, thereby omit volute spring 17.At this moment, also resilient retaining member 4 and jig arm 2 one can be installed.Also can be with the rubber-like part of retaining member 4 as jig arm 2, and can be integrally formed with jig arm 2.Retaining member 4 not necessarily must be installed on the jig arm 2, can according to circumstances be installed on the fixed components such as chassis of disk player.
In above-mentioned example, anchor clamps 1 are adsorbed on the retaining member 4 and are held, the present invention but not only for this example.As: but anchor clamps 1 can make the structure that is supported by retaining member 4 under free rotation state.At this moment, as shown in figure 14, anchor clamps 1 can be installed the portion that is supported 27 that rotates freely by retaining member 4 supportings.Be supported portion 27, the sliding components such as bearing 30 of anchor clamps 1 by keeping anchor clamps 1 to slide smoothly is installed on the retaining member 4.For anchor clamps 1 and rotating disk 3 are attached together, on anchor clamps 1, be embedded with adsorption element 28, adsorption element 29 is installed on rotating disk 3, in this example, adsorption element 28 or adsorption element 29 can be magnet.That is: in above-mentioned example, anchor clamps 1 side is provided with magnet, but in this example, the adsorption element 29 of rotating disk 3 sides is a magnet.
Benefit as the supporting fixture 1 that can be rotated freely by retaining member 4 is: by retaining member 4, often the rotation center to anchor clamps 1 is supported.Like this, CD 5 can prevent that the center of anchor clamps 1 from departing from the center of rotating disk 3 greatly when inserting and being clamped between anchor clamps 1 and the rotating disk 3, prevent to tighten bad.
Can know from top explanation and to know that according to technical scheme 1 described compact disc holder, described device is provided with: place and the rotating disk of rotary CD; Be adsorbed on the rotating disk and keep the anchor clamps of CD; The jig arm of supporting fixture; Keep anchor clamps to make it mobile between the clip position and the position of readiness that breaks away from rotating disk that are adsorbed on the rotating disk, and has a retaining member of the reset force that returns position of readiness, because the reset force of retaining member is less than the absorption affinity of anchor clamps and rotating disk, so needn't mobile jig arm, just can be between position of readiness and clip position mobile anchor clamps.Therefore, do not need the device of mobile jig arm, thereby help to obtain simple, small-sized and disk player cheaply.
In technical scheme 2 described compact disc holders, anchor clamps are adsorbed on the retaining member and are held, so, but the retaining member supporting fixture rotates freely.Load when excessive at anchor clamps, retaining member and anchor clamps break away from, and can prevent to damage anchor clamps or retaining member.
In technical scheme 3 described compact disc holders,, can prevent that anchor clamps are at the footpath of CD direction skew retaining member because anchor clamps remain on the retaining member by pivot.Thus, when chucking optical disk, anchor clamps and center of turntable are coincide, and when playing CD, can prevent that the side direction of anchor clamps, rotating disk, CD from beating.
In technical scheme 4 described compact disc holders, retaining member is the leaf spring with the jig arm one, thus the spring that can produce the reset force that returns position of readiness needn't be set separately, thus reduced component count.
In technical scheme 5 described compact disc holders, retaining member is provided with magnetic, and retaining member and anchor clamps are attached together, so can easily obtain returning the reset force of position of readiness.
