As shown in Figure 2, the front surface in framework 3 is equipped with the flat front panel 18 of essentially rectangular.On this front panel 18, be provided with the disc of coming in and going out along the face direction of disc and insert conveying end 19 for CD 2.That is, CD 2 can insert the inside that conveying end 19 inserts framework 3 from this disc, or inserts conveying end 19 from this disc and discharge to the outside of framework 3.As shown in Figure 5, the front surface of plate 18 is provided with the display part 20 of Access status of the expression CD 2 of lighting a lamp and the ejector button of pushing when wanting to discharge CD 2 21 in front.
Disc inserts conveying end 19 for CD 2 is guided to middle body, has the then shape that reduces slightly of thickness direction size of the thickness direction size maximum of this middle body, past more both ends.In addition, the upper and lower surface of inserting conveying end 19 at disc is provided with from the front face side of front panel 18 towards dip plane 38 that the approaching mutually direction of the interior side direction of framework 3 tilts.This dip plane 38 is used for when inserting disc CD 2 being guided to disc and inserts conveying end 19.
Disc insertion conveying end 19 is made of rectangular aperture along the length direction of front panel 18, and the length of this rectangular aperture is bigger slightly than the diameter of CD 2 thickness long slightly, aspect ratio CD 2.As Fig. 5 and shown in Figure 6, disc insert conveying end 19 the both ends of length direction 19a, 19b is provided with the periphery sliding contact of inserting the CD 2 that takes out from framework 3 slip sheet 23.Slip the imitative chamois leather (urethane resin being immersed in the material that obtains in the dacron) of dermatine that sheet 23 for example uses black, as shown in Figure 7, be installed in accommodating in the recess 24 of the rear side that is formed at front panel 18 by cementing agent etc.
As shown in Figure 2, insert that conveying end 19 inserts or when disc inserts conveying end 19 and discharges at CD 2 from disc, when CD 2 has the position that is in about half towards the foreign side of framework 3, slip sheet 23 with the direction of the insertion removing direction quadrature of CD 2 on peripheral part 2A sliding contact.Thus, carry out sliding contact with respect to the peripheral part 2A of CD 2,, can suppress insertion force or expulsion force so the insertion force or the expulsion force of CD 2 applied load because slip sheet 23.
When inserting CD 2 in the framework 3, apply load to moment when only inserting in the framework 3 about half, the user continues to insert CD 2, gives disc carrying mechanism 60 described later, is installed in by this disc carrying mechanism 60 on the disc installation portion of framework 3.On the other hand, when CD 2 is discharged, apply load outside framework 3, make the discharge rate optimization of CD 2 at the expulsion force of 60 pairs of CDs of disc carrying mechanism.That is, when CD 2 has about half the peripheral part 2A sliding contact of slipping sheet 23 and CD 2 when discharging, thereby apply load, thereby can when the center pit 2a of CD 2 inserts conveying end 19 outside in the face of disc, stop the discharge of CD 2.Thus, the user can clamp in the face of the interior week of the center pit 2a of the CD 2 of disc insertion conveying end 19 outsides and the peripheral part of CD 2, easily takes out CD 2.
As described later, disc carrying mechanism 60 rotates the 1st, the 2nd swivel arm 61,62 by torsion-coil spring 70, when the various CDs 2 of thickness and vary in weight are discharged outside framework 3, slip sheet 23 also when CD 2 inserts conveying end 19 and discharges half left and right sides from disc with the direction of discharging the direction quadrature on peripheral part 2A sliding contact, can eliminate the difference of the expulsion force that causes because of CD 2 kind differences thus, can make each CD 2 stop at best drain position.
Above-mentionedly slip sheet also can insert the length direction of conveying end at disc except can being provided with at the length direction both ends that disc insert conveying end any one end setting.In addition, for a pair of sheet that slips on the both ends that are arranged on length direction, also can be designed to impose on by sliding contact separately the load difference of CD 2.
Rear side at front panel shown in Figure 6 18 is provided with a plurality of buckling pieces, this front panel 18 is installed in the front of framework 3.
In disc drive appts 1, also can replace and slip sheet 23 or panel curtain 30 is set so that the discharge rate of inserting the CD that conveying end 19 discharges from the disc of front panel 18 is limited with slipping sheet 23.Panel curtain 30 is with above-mentioned to slip sheet 23 identical, for example use the imitative chamois leather (urethane resin being immersed in the material that obtains in the dacron) of dermatine of black, as shown in Figure 8, an end to the other end that inserts the length direction of conveying end 19 from disc by cementing agent etc. is installed in accommodating in the recess 31 of the rear side that is formed at front panel 18.
As shown in Figure 9, panel curtain 30 is arranged to, and the following ora terminalis 30a of panel curtain 30 inserts conveying end 19 in the face of disc and as there not being fixing free end such as cementing agent, is positioned at the lower lip 19c sustained height roughly that inserts conveying end 19 with disc.Thus, the lower edge 30a of panel curtain 30 with insert the upper surface 2B sliding contact that conveying end 19 inserts the CD 2 that takes out from disc, can prevent that also dust etc. from entering the inside of framework 3.
When CD 2 when disc inserts conveying end 19 and inserts or discharge, the upper surface 2B sliding contact of the free-ended lower edge 30a of the conduct of this panel curtain 30 and CD 2 and direction insertion removing direction quadrature.Slip the upper surface 22B relatively sliding contact of sheet 23 thus, the insertion force or the expulsion force of CD 2 applied load, can suppress insertion force or expulsion force with respect to CD 2.
Shown in Figure 10 A, when CD 2 inserts in the frameworks 3,, CD 2 is continued to insert by the user although CD 2 is applied load, give disc carrying mechanism 60 and be installed on the disc installation portion.On the other hand, shown in Figure 10 B, when CD 2 is discharged, apply load outside framework 3, make the discharge rate optimization of CD 2 at the expulsion force of 60 pairs of CDs 2 of disc carrying mechanism.Promptly, panel curtain 30 applies load by the 2B of the interarea portion sliding contact with CD 2, so when used thickness and the various CD 2 that varies in weight, even the expulsion force of disc carrying mechanism 60 when excessive, also can prevent that CD 2 from inserting conveying end 19 from disc and flying out for this CD 2.
This occasion, shown in Figure 11 A, 11B, panel curtain 30 is when the insertion of CD 2 and when discharging, upper surface side interarea 2B of portion and the lower face side interarea 2C of portion sliding contact with CD 2, especially when CD 2 is discharged, can suppress the expulsion force of disc carrying mechanism 60 effectively, prevent that CD 2 from inserting conveying end 19 from disc and flying out.
As Figure 12 and shown in Figure 13, panel curtain 30 also can be the structure that is provided with slide connecting part 25, limits the overhang of CD 2 by this slide connecting part 25 and CD 2 sliding contacts of discharging from the disc insertion conveying end 19 of front panel 18.As shown in Figure 14B, slide connecting part 25 uses and panel curtain 30 identical materials, for example, be formed on the center pit 2a non-posting field 32a on every side of the CD 2 shown in Figure 14 A, corresponding with the stage portion 33 between the zone that is formed on the chucking zone 32 that tightened by turntable 47 and outer circumferential side that should chucking zone 32 with thickness, above or below the court of substantial middle portion of the left and right directions of panel curtain 30, give prominence to.Slide connecting part 25 forms as one with panel curtain 30, but also panel curtain 30 can be formed rectangular-shapedly, and slide connecting part 25 sticks on this panel curtain 30 from rear side and forms.
When the 1st, the 2nd swivel arm 61,62 described later rotates under the application of force of torsion-coil spring 70, and CD 2 is when disc inserts conveying end 19 and discharges, a such slide connecting part 25 and a face sliding contact of CD 2, the sliding gradually portion 33 of topping bar.Thus, the sliding friction by slide connecting part 25 is inhibited expulsion force, and CD 2 inserts conveying end 19 from disc and is expelled to center pit 2a in the face of outside position.Therefore, the user can clamp the center pit 2a in the face of the CD 2 of the device outside of disc insertion conveying end 19, easily CD 2 is taken out from disc drive appts 1.
Like this, even disc drive appts 1 also can utilize the sliding contact of slide connecting part 25 to suppress to be applied to expulsion force on the CD 2 when utilizing the 1st, the 2nd swivel arm 61,62 to discharge the diameters CD 2 different with thickness, make each CD 2 extend out to each self-corresponding optimum position.
At this, shown in Figure 14 A, CD 2 the outer circumferential side of the center pit 2a that passes for the engaging teat 48a of turntable 47 that is located at disc drive appts 1 side be formed with as with the non-posting field 32a in the chucking zone of turntable 47 etc. and the posting field 34 that is formed with pit etc.Non-posting field 32a also is formed with the stage portion 33 that puts in the chucking zone 32 on the turntable 47 and realize the location on turntable 47.
Therefore, disc drive appts 1 inserts the disc discharge rate optimization of conveying end 19 in order to make various CDs 2 from the disc that inserts taking-up, and except that forming slide connecting part 25 in the zone corresponding with above-mentioned stage portion 33, for example also can with more slide connecting part 25 is set accordingly than stage portion 33 to the chucking zone 32 of the center pit 2a of CD 2 side.That is, as shown in Figure 14B, disc drive appts 1 also can form slide connecting part 25 to any part in the zone of stage portion 33 accordingly with the center pit 2a of CD 2.
For CD 2 is guided to middle body, disc inserts conveying end 19 and has the then slightly little shape of thickness direction size of the thickness direction size maximum at this middle body, past more both ends.The upper and lower surface of inserting conveying end 19 at disc is provided with from the front face side of front panel 18 towards dip plane 38 that the approaching mutually direction of the interior side direction of framework 3 tilts.This dip plane 38 is used for that when inserting disc CD 2 is guided to disc and inserts conveying end 19.

When CD 2 is pushed out to insertion extracting position shown in Figure 28, the 23 pairs of CDs of being located on both ends 19a, the 19b that disc inserts conveying end 19 of being released by the 1st, the 2nd swivel arm 61,62 of disc carrying mechanism 60 of sheet that slip apply load, make the overhang optimization of CD 2.That is, slip sheet 23 and when outstanding half left and right sides of CD 2, apply load, thereby the center pit 2a that can make CD shown in Figure 28 2 stops at the extrusion position in the face of the outside of disc insertion conveying end 19 with the peripheral part 2A sliding contact of CD 2.Thus, the user clamps from disc with finger and inserts center pit 2a and the peripheral part of conveying end 19 towards the CD 2 of outside, just can easily take out CD 2.
At this, as mentioned above, the 1st and the 2nd swivel arm 61,62 rotates towards approaching mutually direction under the elastic force effect of torsion-coil spring 70, thereby CD 2 is extrapolated towards framework 3.Therefore, because the difference of disc types, then the thickness of disc and weight can produce difference, if CD 2 is discharged on certain disc drain position when only utilizing the elastic force of torsion-coil spring 70 just to be difficult in to use any CD 2 in the multiple CD 2.But, used disc drive appts 1 of the present invention, slip sheet 23 because be provided with at the both ends that disc inserts conveying end 19, so before disc insertion conveying end 19 is discharged about half, utilize the 1st and the 2nd swivel arm 61,62 of the elastic force that is subjected to torsion-coil spring 70 that CD 2 is released at CD 2, when CD 2 when disc inserts conveying end 19 and discharges half left and right sides, at this constantly, slip sheet 23 and apply load with the peripheral part 2A sliding contact of CD 2.Therefore, when the various CD 2 of used thickness and vary in weight, even CD 2 arbitrarily, also can insert extracting position, be that the center pit 2a of CD 2 stops the discharge of CD 2 inserting the position that conveying end 19 exposes towards the outside of framework 3 from disc at disc.
In addition, when plate 18 is provided with panel curtain 30 in front, lower edge 30a by panel curtain 30 or go up the upside interarea 2B of portion of lower edge 30a, 30b and CD 2 or the upper and lower sides interarea 2B of portion, 2C sliding contact, and the expulsion force of disc carrying mechanism 60 is applied load.Thus, disc drive appts 1 is when used thickness and the various CD 2 that varies in weight, even the expulsion force of disc carrying mechanism 60 when excessive, also can prevent that CD 2 from inserting conveying end 19 from disc and flying out for this CD 2.
The 3rd swivel arm 76 is urged under the state of the 3rd abutting member 78 and the peripheral part butt of CD 2 and along arrow c among Figure 27
2Direction is rotated.
With reference to Figure 29, Figure 30 the ejection state of the CD 2 in above-mentioned Figure 11～example shown in Figure 14 is described.
As mentioned above, being pushed out to each CD 2 that disc inserts extracting position by the 1st swivel arm 61 and the 2nd swivel arm 62 inserts conveying end 19 from the disc of front panel 18 and discharges outside framework 3.At this moment, as shown in figure 29, the slide connecting part 25 and CD 2 sliding contacts of the panel curtain 30 that is formed at front panel 18 of disc drive appts 1.Because slide connecting part 25 and the non-posting fields such as stage portion 33 around the center pit 2a that is formed at CD 2 are formed on the central authorities of the length direction of panel curtain 30 accordingly, thus at CD 2 when disc inserts conveying end 19 and discharges, the sliding gradually upward stage portion 33 of CD 2.Therefore, sliding friction by slide connecting part 25 is suppressed the 1st swivel arm 61 that rotated by torsion-coil spring 70 application of forces and the expulsion force of the 2nd swivel arm 62, as shown in Figure 2, CD 2 is inserted conveying end 19 and is expelled to center pit 2a in the face of outside position from disc.Thus, the user can clamp from disc insert the center pit 2a of the CD 2 that conveying end 19 stretches out and disc peripheral part, without the contact history zone just can be easily with CD 2 from disc drive appts 1 taking-up.
Like this, even disc drive appts 1 is when utilizing the 1st, the 2nd swivel arm 61,62 to discharge the diameters CD 2 different with thickness, also the expulsion force of inhibiting effect on CD 2 can be come, the optimum position corresponding can be expelled to each CD 2 by the sliding contact of slide connecting part 25.
In addition, when slide connecting part 25 is formed corresponding to the center pit 2a of CD 2, as shown in figure 30, slide connecting part 25 on one side with the one side sliding contact of CD 2 on one side and center pit 2a buckle.Therefore, in disc drive appts 1, even the expulsion force that causes in the rotation of the 1st swivel arm 61 and the 2nd swivel arm 62 is concerning the diameter of CD 2 and thickness etc. when excessive, also can be by slide connecting part 25 and center pit 2a buckle, prevent that CD 2 from inserting conveying end 19 from disc and flying out, can realize the best discharge rate that center pit 2a stops in the position of stretching out from disc insertion conveying end 19.
The present invention is not limited to be applied on the above-mentioned plug-in type disc drive appts 1 that is loaded on the notebook personal computer 1000, can be widely used in CD is carried out on the disc drive appts of home-use, vehicle mounted of the record of information signal and/or regeneration and game machine etc.
The present invention is not limited to the foregoing description with reference to description of drawings, obviously concerning the professional and technical personnel under the situation that does not break away from appending claims and aim thereof, change, the displacement that can carry out various changes, replace or be equal to.
