Embodiment

The invention will be further described below in conjunction with drawings and Examples

Embodiment 1 as shown in Figure 1 and Figure 2.Optical disk cartridge is made of hollow frusto-conical shape enclosing cover 1 and discoid base plate 2.The center of enclosing cover 1 is by a through hole 11, and the upper-end inner diameter of enclosing cover 1 is more bigger than the external diameter of the CD that will collect, and bottom diameter is bigger than upper-end inner diameter.Form step around on base plate 2 continuously, the lower end of enclosing cover 1 embeds in the step from the top down.Begin to stretch out supporting rod 3 from the central part of base plate 2.As prior art, supporting rod 3 passes from the hole of the CD that will collect.Supporting rod 3 is made of the vertical rod 32 of the inboard of three inserted sheets 31 that are in periphery and inserted sheet.Each inserted sheet 31 is placed on the base plate 2 and can moves freely within the limits prescribed along the radial direction of supporting rod 3.Vertical rod 32 is the holders that can freely rotate on base plate 2.Have threaded hole 32A in the upper end of vertical rod 32, the threaded hole 32A of the screw thread 33A of handle 33 and vertical rod 32 upper ends is meshing with each other.Can see three radial finedraws 23 that the central part of base plate 2 has a hole 22 and is connected with hole 22 by Fig. 2.The shaft collar 4 of a similar Deep-fried doughnut sample is housed below the central part of this external base plate 2, and porose 41 reach three radial cracks 42 that are connected with hole 41 on this shaft collar 4.During installation on the shaft collar 4 crack 42 will with its top base plate 2 on finedraw 23 corresponding, supporting rod 3 is installed on the shaft collar 4 by base plate 2.The xsect of three inserted sheets 31 is partial arc shape, and its medial surface above-below direction has three thrust 31A.The xsect of vertical rod 32 is rounded, has three places that three thrust 32B are also arranged on its circumferencial direction.The elasticity such as turn that utilizing does not draw among the figure comes part in addition firmly make sliding pin 43 close to the center of shaft collar 4.At the place, bottom surface of each inserted sheet 31, sliding pin 43 passes crack 42 and finedraw 23 and the dish 4 that is fixed is clamped fixing.Each inserted sheet 31 can move freely along finedraw 23 like this.The flange 32C that forms below vertical rod 32 is placed in the hole 41 of shaft collar 4.4 of shaft collars support that vertical rod 32 rotates freely in base plate 2.

Shown in Fig. 3 (A).In supporting rod 3, the formed thrust 32B of the outer peripheral face of the formed thrust of the medial surface of inserted sheet 31 (annex) 31A and vertical rod 32 is in when staggering state, each inserted sheet 31 is close mutually on the radial direction of supporting rod 3, and the position that the periphery of thrust 31A and vertical rod 32 does not form thrust is in contact with one another.The external diameter of supporting rod 3 is littler than the aperture of the CD that will deposit, and supporting rod 3 can be movable in the hole of CD.At this moment the external diameter of supporting rod 3 is exactly first external diameter of supporting rod 3.Supporting rod 3 can be easy to insert from the hole of CD and take out, and CD also can freely overlay on the base plate.Can see from the enlarged drawing of Fig. 3: the head of thrust 31A is spill, state from Fig. 3 (A), vertical rod 32 rotations 60 degree, the formed thrust 32B of outer peripheral face of formed thrust 31A of the medial surface of inserted sheet 31 and vertical rod 32 is in mated condition.Can see from the enlarged drawing of Fig. 3: because the head of thrust 31A is spill, the mated condition of thrust 32B and thrust 31A can be kept.Inserted sheet 31 moves laterally along the radial direction of supporting rod 3 separately, and the external diameter of supporting rod 3 is bigger slightly than the aperture of the CD that will deposit, the inner peripheral surface crimping mutually in the lateral surface of inserted sheet 31 and CD hole, thus limited the mobile of CD.At this moment the external diameter of supporting rod 3 of circumference that is crimped on the hole of CD is exactly second external diameter of supporting rod 3.

As shown in Figure 1, above base plate 2, take off, utilize the hole of CD to pass supporting rod CD is overlayed on the base plate 2 at enclosing cover 1.After enclosing cover 1 covers on the base plate 2, the screw thread 33A on the handle 33 is meshed with each other with the threaded hole 32A that opens in vertical rod 32 upper ends by the through hole on the enclosing cover 1.Handle 33 just can make vertical rod 32 rotate, and to Fig. 3 (A) state, inserted sheet 31 is close mutually from Fig. 3 (B) state, and CD just can take out and put into well.Otherwise to Fig. 3 (B) state, moving of CD just is restricted from Fig. 3 (A) state.Change must make sliding pin 43 close to the center of shaft collar 4 with other part of elasticity howsoever.

When the screw thread 33A on handle 33 and the threaded hole 32A of vertical rod 32 fully mesh, the Outboard Sections of screw thread 33A and enclosing cover 1 crimping on the bottom surface of handle 33, thus keeping enclosing cover 1 to cover state above the base plate 2.

When the lateral surface of inserted sheet 31 rubber Rubber, flexible plastic and foam sponge etc. had the material formation of soft character, CD just can be fixed more securely.Because not with the mutual crimping of inner peripheral surface in the hole of CD, with the lateral surface of the corresponding inserted sheet 31 in inner peripheral surface upper end in the hole of uppermost CD pressurized and loosen and come not, the formed here external diameter of the inserted sheet 31 just internal diameter than the hole of CD is big.The do not deform crimping of part of the lateral surface that circumference has been subjected to inserted sheet 31 on the hole of uppermost CD, CD has been subjected to downward acting force, and moving of CD is restricted more.

As shown in Figure 4, there are three places to extend on the inside surface on enclosing cover 1 downwards and stop other part 51.In the process that each inserted sheet 31 outwards moves, in case the upper end of the lateral surface of inserted sheet 31 contacts with stopping other part 51, inserted sheet 31 just can't outwards move again.The scope that inserted sheet 31 outwards moves also is restricted.

The main variation of embodiment 2 present embodiments is supporting rod 3.As shown in Figure 5, under the situation that vertical rod 32 moves up, formed thrust 32B docks mutually with the formed thrust 31A of the medial surface of each inserted sheet 31 on the periphery of vertical rod 32, each inserted sheet 31 outwards moves along the radial direction of vertical rod 32, the mutual crimping of the periphery in the lateral surface of each inserted sheet 31 and CD hole, moving of CD just is restricted.Under the situation that this external vertical rod 32 moves down, formed thrust 32B does not dock with the formed thrust 31A of the medial surface of each inserted sheet 31 on the periphery of vertical rod 32, each inserted sheet 31 just can move inward along the radial direction of vertical rod 32, by the external diameter of the supporting rod that lateral surface constituted 3 of each inserted sheet 31 internal diameter less than the CD hole, CD just can insert on supporting rod 3 and take off.

Can see from the enlarged drawing of Fig. 5: because the head of thrust 31A is spill, the mated condition of thrust 32B and thrust 31A can be kept.

The main variation of embodiment 3 present embodiments still is supporting rod 3.As shown in Figure 6, each inserted sheet 31 is made by the rubber-like resin material, comprises the body 31A and the rock body 31B that have hinge 31C.For the body 31A that has hinge 31C, rock body 31B can freely be shaken.Begin to have thrust 31D from body 31A lower surface.Medial surface at rock body 31B has elongated thrust 31E up and down.Three equidistant places have the bottom of elongated up and down thrust 32B. vertical rod 32 to form flange 32C on the peripheral direction of similar cylindrical vertical rod 32.There is a hole 2A that can make vertical rod 32 begin to pass from the following side in central authorities at base plate 2.On base plate 2 and hole 2A around have three recess 2B can for three inserted sheet 31 inserted sheet 31D separately from top embedding.After beginning thrust 31E embedded recess 2B from the upper face side of base plate 2, inserted sheet 31 just stood in base plate 2 above.Vertical rod 32 is after side begins to pass hole 2A below base plate 2, and vertical rod 32 just places the inboard of inserted sheet 31.The flange 32C of vertical rod 32 and the butt joint of the bottom surface of base plate 2, again because dish 33 is embedded in the recess that does not show the figure that the bottom surface of base plate 2 forms from the below, the flange 32C of vertical rod 32 is sandwiched in the bottom surface of base plate 2 and the centre of dish 33, and vertical rod 32 just can rotate freely on base plate 2.

As shown in Figure 7, in supporting rod 3, when the formed thrust 32B of lateral surface of formed thrust 31E of the medial surface of inserted sheet 31 and vertical rod 32 is not in butt joint, because the rock body 31B that the elastic force of hinge 31C acts on each inserted sheet 31 draws close along the radial direction of supporting rod 3 is mobile mutually, thrust 31E does not have the position of the thrust 32B of formation to dock mutually with the lateral surface of vertical rod 32.At this moment, the external diameter of supporting rod 3 is littler than the internal diameter in the hole of the CD that will deposit, and supporting rod 3 interts in the CD hole easily, has formed first external diameter.CD on the base plate 2 can freely stack and take off.Vertical rod 32 is turned over 60 degree, shown in Fig. 7 (B), because the formed thrust 31E of medial surface of inserted sheet 31 and the formed thrust 32B butt joint of the lateral surface of the vertical rod 32 that is in relative position, the rock body 31B on each inserted sheet 31 outwards moves along the radial direction of supporting rod 3.At this moment the external diameter of supporting rod 3 is more bigger than the internal diameter in the hole of the CD that will deposit, and supporting rod 3 is crimped on the circumference in CD hole, has formed second external diameter of supporting rod 3.Just because of this, the outer peripheral face of the rock body 31B on the inserted sheet 31 is crimped on the inner peripheral surface in CD hole, and such crimping has limited moving of CD.Also as shown in the enlarged drawing of Fig. 7, the head of thrust 31E is spill, and the head of thrust 32B embeds this concave portions, and the outer peripheral face of the rock body 31B on inserted sheet 31 is crimped on the state of the inner peripheral surface in CD hole and just can keeps.

The same with embodiment 1, the rotation of vertical rod 32 can be operated by the handle that does not show among Fig. 6.

In sum, the present invention is not limited to above-mentioned embodiment, no matter do any variation on its shape or structure, as long as have in supporting rod that external diameter can change and the supporting rod inserted sheet is arranged, and the optical disk cartridge of vertical rod all falls into protection scope of the present invention.
