The engagement claw 37 is engaged, whereby the upper lid 12 is locked in a state where the upper opening 25 of the main body 11 is closed. [Selection] Figure 20

Description

  The present invention relates to a disk storage case, and more particularly to a disk storage case in which a plurality of disks are stored at a predetermined interval in the axial direction while their axes coincide with each other.

  In order to transport a hard disk or a disk-shaped substrate for manufacturing the hard disk and to move it between manufacturing processes, for example, a disk storage case as shown in US Pat. No. 4,557,382 is used. The disk storage case is configured to store a plurality of disks at predetermined intervals in the axial direction while their axes coincide with each other by guide grooves formed inside the main body. Here, the top opening of the main body is closed by the top cover, and the bottom opening is closed by the bottom cover, so that the disc stored therein can be safely transported or stored without being contaminated. ing.

  1 to 4 show specific examples of hard disk cases in which 25 hard disks having a size of 2.5 inches are accommodated. The case is assembled from a main body 1, an upper lid 2 that closes an upper opening of the main body 1, and a bottom lid 3 that closes a bottom opening of the main body 1. As shown in FIG. 3, guide grooves 4 are formed on both side surfaces of the main body 1, and these guide grooves 4 hold the outer periphery of a 2.5-inch hard disk so that their axes coincide with each other. They are stored at predetermined intervals in the axial direction.

  U-shaped cuts 5 are formed on the side surfaces of both ends of the main body 1 in the length direction, and these cuts 5 enable the hard disk to be stored or taken out by the robot hand from both sides of the main body 1. The U-shaped notch 5 is closed by the tongue piece 6 of the upper lid 2. The tongue piece 6 is formed with an engaging claw 7 at a tip side and a lower end side thereof, and these engaging claws 7 are formed on the peripheral portion of the U-shaped cut 5 of the main body 1 as shown in FIG. It is adapted to be locked to the formed rib 8.

  According to the configuration of such a conventional hard disk case, the locking claw 7 of the tongue piece 6 that closes the U-shaped cut 5 of the main body 1 is formed on the peripheral edge of the U-shaped cut 5 of the main body 1. The main body 1 is closed by the upper lid 2 in a state where the U-shaped cut 5 is closed by the tongue piece 6, and the upper lid 2 is locked.

  Therefore, particularly when the engaging claw 7 of the tongue piece 6 is engaged with the rib 8 and when the engagement is released, particles due to the material constituting the engaging claw 7 and the rib 8 are generated between them. Particles get over the rib 8 and enter the main body 1 through the U-shaped cut 5 of the main body 1. Therefore, the discs stored in the main body 1, which are located at both ends in the length direction, are fouled by the pudicle generated when the engaging claws 7 and the ribs 8 are engaged and released. There is a high probability that in some cases these fouled discs must be discarded. Therefore, when such a case is used for transportation or storage of a hard disk or an intermediate product thereof, there is a problem that the yield of the hard disk is lowered, thereby increasing the cost of the hard disk.

U.S. Pat. No. 4,557,382

  The subject of this invention is providing the disk storage case which prevented the disk accommodated in the inside of a main body from being polluted with opening and closing of an upper cover.

  Another subject of the present invention is a disc storage case in which the upper lid of the main body, in which the axes of the discs coincide with each other and are stored at predetermined intervals in the axial direction, is closed by the upper lid. It is an object of the present invention to provide a disk storage case in which a disk stored inside is prevented from being contaminated by particles generated by friction of an engaging portion for locking at the time.

  Still another problem of the present invention is that a plurality of discs are formed at both ends of a main body of the disc storage case in a disc storage case in which a plurality of discs have their axes coincide with each other and are stored at predetermined intervals in the axial direction. The particles generated by the locking mechanism by the engaging part for closing the cuts that have been made contaminate the discs located at both ends in the axial direction, and this causes the discs on both sides facing the cut to be fouled and discarded. It is to provide a disc storage case that is to be prevented.

  Still another object of the present invention is to provide a disk storage case in which the dimensions of the mounting portion of the hard disk storage case are not changed by a lock mechanism for locking the tongue pieces that close the cuts on both sides of the main body. is there.

  The above-described problems and other problems of the present invention will be clarified by the technical idea of the present invention described below and the embodiments thereof.

The main idea of the present application is that a guide groove for receiving the outer peripheral portion of the disk is formed on the inner surface at a predetermined interval, and the plurality of disks are aligned with each other by the guide groove and stored at a predetermined interval in the axial direction. And a main body in which cuts cut from above are formed at both ends in the axial direction, and
An upper lid integrally closed with a tongue that closes the upper opening of the main body and closes the cuts at both ends in the axial direction;
A bottom lid for closing the lower opening of the body;
A projecting piece is provided continuously at the tip of the tongue piece of the upper lid, and an engaging claw is provided on the projecting piece, and the engaging claw is provided on the outer side at both ends in the longitudinal direction of the bottom lid. The present invention relates to a disc storage case that is locked by a locking portion and locked in a state where the upper lid is closed.

  Here, the engaging claw may be provided on the inner side of the protruding piece, and when the protruding piece is pulled outward, the engaging claw is released from the engaging portion of the bottom lid and the lock may be released. Moreover, the latching | locking part of the said bottom cover may be comprised from the step part opened below the outer side of the both ends of the longitudinal direction of the said bottom cover. The engaging position of the engaging claw by the engaging portion may be near the lower end of the case and below the lower edge of the cut of the main body. Moreover, the said upper cover and the said bottom cover may be comprised from the mutually same resin material.

The main idea of the present application is that a guide groove for receiving the outer peripheral portion of the disk is formed on the inner surface at a predetermined interval, and the plurality of disks are aligned with each other by the guide groove and stored at a predetermined interval in the axial direction. And a main body in which cuts cut from above are formed at both ends in the axial direction, and
An upper lid integrally closed with a tongue that closes the upper opening of the main body and closes the cuts at both ends in the axial direction;
A bottom lid for closing the lower opening of the body;
A projecting piece is provided continuously at the tip of the tongue piece of the upper lid, and an engaging claw is provided on the projecting piece, and the engaging claw is provided on the outer side at both ends in the longitudinal direction of the bottom lid. The upper lid is locked in the closed state by being locked by the locking portion.

  Therefore, according to the disc storage case having such a configuration, the engaging claw of the protruding piece is locked to the locking portion on the outer side at both ends in the longitudinal direction of the lid, and the lid closes the upper opening of the main body. In order to lock the tongue piece of the lid, the locking is performed without engaging the engaging claw with the peripheral edge of the cut of the main body. Therefore, compared with the case of locking at the notch rib portion of the main body, the engaging position by the engaging claw is located outside the main body and below, so that the engaging claw and the locking portion are locked. Alternatively, even if particles are generated at the time of release, such particles do not enter the inside of the main body through the cut. Therefore, the discs on both sides in the axial direction facing the notches in the plurality of discs housed inside the main body are prevented from being contaminated by particles, and this prevents a decrease in the yield of the discs housed inside. It becomes possible to avoid an increase in the cost.

  The present invention will be described below with reference to an embodiment shown in the drawings. As shown in FIGS. 5 and 6, the disk storage case of the present embodiment includes a main body 11 for storing a disk therein, an upper lid 12 that closes an upper opening of the main body 11, and a bottom opening of the main body 11. The bottom cover 13 is closed, and these are combined to form a disc storage case. In the closed state, all the openings of this case are closed, so that dust does not enter from the outside, and it is possible to reliably protect the disk stored inside from the dirty state.

  Next, the structure of the main body 11 of the disk storage case will be described with reference to FIGS. The main body 11 is a case having a substantially rectangular parallelepiped shape, and both sides in the longitudinal direction are constituted by flat plate-like portions 15. The flat plate-like portion 15 is a bulging portion 16 whose upper portion protrudes outward. A rib 17 extending in the lateral direction is formed on the outer side of the upper end side of the bulging portion 16, and the rib 17 presses the lower edge of the peripheral wall portion of the upper lid 12. In addition, a plurality of guide grooves 18 are formed inside the bulging portion 16 at a predetermined interval from each other. The guide groove 18 is for receiving the outer peripheral portion of the disk accommodated therein, and the number of the disks accommodated is determined by the number of the guide grooves 18. In the present embodiment, 25 guide grooves 18 are sequentially formed at predetermined intervals in the lateral direction.

  A portion on the short side of the main body 11 is constituted by the side wall portion 20. The side wall portion 20 is configured to connect the flat plate-like portions 15 on both sides, and a relatively large U-shaped cut 21 is formed in the side wall portion 20 so as to be cut downward from above. . A rib 22 is formed on the peripheral edge of the U-shaped cut 21 so as to protrude outward. The upper part of the main body 11 is an upper opening 25, and the lower part is a lower opening 26. That is, the main body 11 has an elongated frame shape in which the upper part and the lower part are opened.

  Next, the structure of the upper lid 12 that closes the upper opening 25 of the main body 11 will be described with reference to FIGS. The upper lid 12 is composed of an upper plate portion 30 that has a substantially flat plate shape as a whole. As shown in FIG. 13 and FIG. 14 in particular, the upper plate portion 30 is formed with concave grooves 31 extending in the longitudinal direction on both sides thereof in parallel with each other. A pair of parallel deformation preventing ribs 38 is formed on the upper surface of the upper plate portion 30 so that the flat plate portion 30 is not deformed into a bow shape in the length direction. A peripheral wall portion 32 is formed on the peripheral edge of the upper plate portion 30. These peripheral wall portions 32 are engaged with the upper edge of the main body 11 from the outside. In addition, a pair of presser ribs 33 are formed on the lower surface of the upper plate portion 30 of the upper lid 12 so as to extend in the longitudinal direction in parallel to each other. The presser ribs 33 are formed with recesses 34 at predetermined intervals. Yes. The concave portion 34 is configured to press the outer peripheral portion of the disk stored in the main body 11 from above.

  Tongue pieces 35 are formed on both sides of the upper lid 12 in the length direction so as to protrude downward. The tongue piece 35 is for closing the U-shaped cuts 21 on both sides of the main body 11, and is formed with a convex portion 39 protruding inward in a shape corresponding to the U-shaped cuts 21. A protruding piece 36 is further formed on the lower end side of the tongue piece 35, and an engaging claw 37 is formed on the inner side of the lower end of the protruding piece 36.

  Next, the structure of the bottom lid 13 that closes the bottom opening of the main body 11 will be described with reference to FIGS. The bottom lid 13 constitutes an elongated flat lid, and a long side rib 41 and a short side rib 42 are formed on the peripheral edge thereof. The short side ribs 42 are formed so as to be immersed inward, whereby the outer side portions of the short side ribs 42 become recesses 43. The lower portion of the recess 43 is composed of a bottom protruding piece 44. A U-shaped locking portion 45 having a U-shaped cross-section and opened downward is formed so as to cross the substantially central portion of the bottom protruding piece 44. The U-shaped locking portion 45 engages with an engaging claw 37 formed on the protruding piece 36 at the lower end of the tongue piece 35 of the upper lid 12, thereby closing the upper lid 12 and the upper opening 25 of the main body 11. It locks in the state.

  Next, the assembly structure of the disc storage case composed of the main body 11, the upper lid 12, and the bottom lid 13 having the above-described configuration will be described. For example, 25 hard disks 50 or a substrate made of aluminum or glass for manufacturing the hard disks is held in the main body 11 by the guide grooves 18 inside the bulging portion 16 (FIG. 20). reference). Here, the disc 50 whose outer peripheral portion is held by the guide groove 18 is pressed by the concave portion 34 of the pressing rib 33 formed on the lower surface of the upper lid 12. Therefore, the internal disk is held in a stable state. FIG. 20 particularly shows a part (two) of these disks 50. When a predetermined number of disks 50 are stored in the main body 11, the bottom opening 26 is covered with the bottom cover 13 and the top opening 25 is closed using the top cover 12. As a result, the disk storage case is closed. Therefore, the disc accommodated in the inside is accommodated in a sealed space composed of the main body 11, the top lid 12, and the bottom lid 13, and foreign matter such as dust from the outside is prevented from adhering.

  Here, in particular, the tongue pieces 35 formed on both sides of the upper lid 12 close the U-shaped cuts 21 of the side wall portion 20 of the main body 11. As shown in FIGS. 20 and 21, the tongue piece 35 is locked on the outer side portion of the short side rib 42 of the bottom lid 13, as shown in FIGS. 20 and 21. This is achieved by locking to the U-shaped locking part 45 formed in the above. By such an engaging structure of the engaging claw 37 of the protruding piece 36 and the U-shaped locking portion 45 of the bottom lid 13, the upper lid 12 covering the upper opening of the main body 11 is not only fixed to the main body 11. The lower bottom lid 13 is locked. That is, the upper lid 12 and the bottom lid 13 are locked to each other with the main body 11 sandwiched from above and below, and not only the upper lid 12 but also the bottom lid 13 are locked and fixed to the main body 11.

  In general, in such a disc storage case, the main body 11 is molded from a polycarbonate resin mixed with, for example, carbon black. On the other hand, the top lid 12 and the bottom lid 13 are each composed of an injection molded body of polypropylene. That is, in order to lock the upper lid 12, the engagement claw 37 of the upper lid 12 is not engaged with the rib 22 of the U-shaped cut 21 of the main body 11 made of a different material, but the U-shape of the bottom lid 13 made of the same material. It will be locked by the locking part 45. Therefore, an engagement structure between different materials is avoided. In addition, the engagement structure of the engagement claw 37 of the protruding piece 36 of the tongue piece 35 of the upper lid 12 and the U-shaped locking portion 45 of the short side rib 42 of the bottom lid 13 is from the lower edge of the arc-shaped cut 21. Is also formed on the outer side of the main body 11. Therefore, even if particles are generated due to friction between the engaging claw 37 and the U-shaped locking portion 45 during locking or unlocking, such particles will be U-shaped cuts 21. Therefore, the disk 50 housed in the main body 11 is reliably prevented from being contaminated, in particular, the both ends in the horizontal direction in FIG. The Therefore, it is possible to avoid a decrease in yield due to the contamination of the discs 50 at both ends in the longitudinal direction of the main body 11 in FIG. 20, thereby preventing an increase in the cost of the hard disk. It becomes possible.

  While the present invention has been described with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the technical idea of the present invention. For example, the design of the disk storage case of the present embodiment can be changed in various ways with respect to the size and number of disks stored therein. Further, the disc to be stored is not limited to a semi-finished product or a finished product for manufacturing a hard disk, and a disc used for various other purposes can be stored.

  The present invention can be used as a disk storage case for transporting and storing a hard disk, its master, or a semi-finished product.
