This torsion-coil spring 75, as Figure 23 (a) and (b), by being formed at the 1st coil portion 76 of pars intermedia, the 2nd arm 75b on the part that be formed with the 1st arm 75a that ends with component of the strobe 65 card, is supported on folder body 5.

The 1st spire 76 is formed with the thickness of regulation by repeatedly reeling, the 1st arm 75a extends from a distolateral 76a of thickness direction, and the 2nd arm 75b extends from another distolateral 76b of thickness direction.The line footpath of the 1st spire 76, the number of turn, free angle can carry out various designs, the selected torsion-coil spring that optimum value is arranged.

The 1st arm 75a that extends from the 1st spire 76 forms the fastener 77 that ends with component of the strobe 65 cards at leading section.This fastener 77 comprises: the extension 77a that extends from the leading section of the 1st arm 75a; The rising portions 77b that generally perpendicularly bends towards coiling direction from the bearing of trend of this extension 77a with the 1st spire 76; And the front end of rising portions 77b further with the bend 77c of the 1st arm 75a almost parallel ground bending, integral body forms roughly コ font.The bend 77c of fastener 77 has predetermined angular θ with the bearing of trend with the 1st arm 75a ₁The form bending.This fastener 77 inserts rising portions 77b in the stop hole 72 of front end of the volute spring installation sheet 71 be located in component of the strobe 65 from the open end, only torsion-coil spring 75 is bearing on the component of the strobe 65 by card.

Here, the bend 77c of fastener 77 has predetermined angular θ with the bearing of trend with the 1st arm 75a ₁The form bending, so component of the strobe 65 also can stop fastener 77 deviating from from stop hole 72 during by on-off action.That is, as shown in figure 24, torsion-coil spring 75 is by the front end bending of fastener 77, and bend 77c side below volute spring installation sheet 71 is extended setting.Therefore, in the on-off action of component of the strobe 65, even torsion-coil spring 75 in Figure 24 the swing of arrow H direction or component of the strobe 65 in Figure 24 during the swing of arrow I direction, the bend 77c of fastener 77 also with the lower face butt of volute spring installation sheet 71, so can prevent the disengaging that engages of torsion-coil spring 75 and component of the strobe 65.

As Figure 25 (a) and (b),, fastener 77 has predetermined angular θ from the bearing of trend of the 1st arm 75a by being bent to form to extension 77a and bend 77c ₂And θ ₃, can prevent further that torsion-coil spring 75 breaks away from from stop hole 72.Promptly, as shown in figure 26, torsion-coil spring 75, be bent to form on extension 77a and bend 77c 2, having predetermined angular by the leading section that makes fastener 77, extension 77a extends towards the upper face side of volute spring installation sheet 71, and bend 77c side below volute spring installation sheet 71 is extended.Therefore, in the on-off action of component of the strobe 65, even torsion-coil spring 75 or component of the strobe 65 in the Figure 26 that becomes above-below direction arrow H direction or during the swing of I direction, the extension 77a of fastener 77 also can with the last facial butt of volute spring installation sheet 71, and the lower face butt of bend 77c and volute spring installation sheet 71, break away from engaging of component of the strobe 65 so can prevent torsion-coil spring 75.

As Figure 23 and shown in Figure 25, the 2nd arm 75b of torsion-coil spring 75 is formed with and makes torsion-coil spring 75 rotate the 2nd spire 78 that engages with folder body 5 freely.The 2nd spire 78 is by repeatedly reeling on the contrary with the coiling direction of above-mentioned the 1st spire 76, forms towards a distolateral 76a of the thickness direction of the 1st spire 76.78 rotations of the 2nd spire are installed on the fulcrum post of establishing 42 of dashing forward on the inner face that presss from both sides body 5 freely.The 2nd spire 78 is identical with above-mentioned the 1st spire 76, can carry out various designs to line footpath, the number of turn, free angle, the selected torsion-coil spring that optimum value is arranged.

These torsion-coil spring 75, the 1 spires 76 and the 2nd spire 78 coiling directions multiturn ground of reeling on the contrary forms, thereby can suppress the thickness of torsion-coil spring 75 integral body, realizes the slimming of folder body 5.Promptly, in having the torsion-coil spring of a plurality of spires, when the coiling direction with each spire forms equidirectional, then the 2nd spire 78 from the position of another distolateral 76b of the 1st spire further another the distolateral 76b towards the thickness direction of the 1st spire 76 reel, so the thickness of the 1st spire 76 adds the thickness of the 2nd spire 78, cause the thickness of spring integral body to increase, thereby the thickness of the folder body of folding and unfolding torsion-coil spring is increased.And the thickness that inserts the disc drive appts that takes out such disc folder also increases.

But, according to torsion-coil spring 75 of the present invention, become opposite by the direction that the 1st spire 76 and the 2nd spire 78 are reeled mutually, the 2nd spire 78 is reeled towards a distolateral 76a of the 1st spire 76, the thickness of spring integral body can be suppressed to arbitrary thickness of the 1st or the 2nd spire 76,78.

As shown in figure 27, disc folder of the present invention, the 2nd spire 78 of torsion-coil spring 75 is formed towards the front end of thickness direction reduced gradually, and the upright fulcrum post of being located on the folder body 5 42 that engaged of the 2nd spire 78 also form towards the front end of upright set direction reduced gradually.

That is, the diameter D1 of the base end side of the 2nd spire 78 coiling directions of torsion-coil spring 75 is bigger than the diameter D2 of the front of coiling direction, is wound into towards point diameter and dwindles gradually.Fulcrum post 42 on the folder body 5 that the 2nd spire 78 is engaged, the diameter D3 that forms the base end side that founds set direction is bigger than the diameter D4 of the front of upright set direction, dwindles gradually towards point diameter.The diameter D1 of each base end side of the 2nd spire 78 and fulcrum post 42 and D3 form roughly the same, and the diameter D2 and the D4 of each front form roughly the same.Fulcrum post 42 forms the thickness h height than the 2nd spire 78, from the base end part height be h the position for the roughly the same diameter D4 of diameter D2 of the leading section of the 2nd spire 78.

According to such disc folder 1, engage with fulcrum post 42 by the 2nd spire 78, the 2nd spire 78 can seamlessly engage with fulcrum post 42 from cardinal extremity to the front end of coiling direction, and the 2nd spire 78 that can prevent when torsion-coil spring 75 from rotating along with the on-off action of component of the strobe 65, becomes rotating fulcrum is loosening.Because torsion-coil spring 75 prevents with respect to loosening having obtained of folder body 5, thus can prevent disc folder 1 use in torsion-coil spring 75 come off or the disengaging that engages of torsion-coil spring 75 and component of the strobe 65 from folder body 5.

When component of the strobe 65 was in the position that head closes with peristome 13, this torsion-coil spring 75 was towards keeping head with the arrow B direction application of force among Figure 28 of peristome 13 closed conditions.When loading when disc folder 1 insertion disc drive appts and by holder, the gate open operation sheet that then is formed at the disc drive appts side enters in the gathering sill 43 of the side 8 that is formed at folder body 5, from the moving direction downstream of component of the strobe 65 and brace 68 butts of component of the strobe 65, component of the strobe 65 is restricted towards the mobile of direction of insertion, with respect to the folder body 5 that is loaded on gradually in the disc drive appts, be that the arrow A direction moves gradually among Figure 28 with peristome 13 open directions towards making head.Thus, torsion-coil spring 75 is a rotating fulcrum with the fulcrum post 42 that the 2nd spire 78 rotates engaging freely, and move towards the arrow A direction of the moving direction of component of the strobe 65 position that is formed at the 1st spire 76 of loose central part.When torsion-coil spring 75 has surpassed the position of fulcrum post 42 of the moving direction side that is positioned at component of the strobe 65, then application of force direction upset.When application of force direction was overturn, torsion-coil spring 75 so that its arrow A direction in Figure 29 moves, was that the arrow A direction moves towards making head with peristome 13 open directions to component of the strobe 65 application of forces, and was maintained on the position that head opens with peristome 13.

When carrying out that component of the strobe 65 is maintained at head with the disc folder 1 of peristome 13 release positions during from discharging operation that disc drive appts takes out, component of the strobe 65 with the action opposite with above-mentioned insert action with respect to folder body 5 gradually relatively in Figure 28 the arrow B direction move, the 1st spire 76 at center also in the same direction arrow B direction moves.When component of the strobe 65 further moves towards the arrow B direction, when the 1st spire 76 of torsion-coil spring 75 has surpassed the position of fulcrum post 42 of the moving direction side that is positioned at component of the strobe 65, then application of force direction upset.When application of force direction was overturn, torsion-coil spring 75, moved towards the direction that head is closed with peristome 13 so that its arrow B direction in Figure 28 moves component of the strobe 65 application of forces, and was maintained on the position that head closes with peristome 13.

Like this, the component of the strobe 65 that is subjected to torsion-coil spring 75 application of forces is subjected to the application of force of torsion-coil spring 75 and is supported on head each position with the off-position of peristome 13 and release position, thereby can keep head reliably and close or opened state with peristome 13.

During the on-off action of this component of the strobe 65, torsion-coil spring 75 and component of the strobe 65, the front end of the fastener 77 of the 1st arm 75a by being formed at torsion-coil spring 75 is bent, bend 77c side below volute spring installation sheet 71 is extended, even so torsion-coil spring 75 arrow H direction swing in Figure 24 in the on-off action of component of the strobe 65, or component of the strobe 65 arrow I direction when swing in Figure 24, the bend 77c of fastener 77 also with the lower face butt of volute spring installation sheet 71, break away from engaging of component of the strobe 65 so can prevent torsion-coil spring 75.

In addition, as shown in figure 26, be bent to form on extension 77a and bend 77c 2, having predetermined angular by the fastener 77 that makes torsion-coil spring 75, extension 77a extends towards the upper face side of volute spring installation sheet 71, and bend 77c side below volute spring installation sheet 71 is extended.Therefore, in the on-off action of component of the strobe 65, even torsion-coil spring 75 or component of the strobe 65 in the Figure 26 that becomes above-below direction arrow H direction or during the swing of I direction, the extension 77a of fastener 77 also can with the last facial butt of volute spring installation sheet 71, and the lower face butt of bend 77c and volute spring installation sheet 71, break away from engaging of component of the strobe 65 so can prevent torsion-coil spring 75.
