Description

  The present invention relates to a disk storage case for storing a recording medium disk such as a CD, a DVD, or a BD, and more particularly to a side index mounting structure.

  As a disc storage case for storing a recording medium disc such as a CD (Compact Disc), a DVD (Digital Versatile Disc), a BD (Blu-ray Disc), etc., a disc tray for detachably holding the recording medium disc, and this disc tray A housing having a pair of case halves that are connected to each other at one end and can be freely opened and closed is widely used (Patent Document 1).

  In such a disc storage case, generally, an index card is attached to each of the inner surfaces of the pair of case halves, and at least one of the index cards extends to the side of the storage case and forms a side index for displaying a title and the like. The side index is provided on the connection side of the pair of case halves and / or on the opposite side.

  In the case of a disk storage case having a single disk tray, a thickness of 10 mm has been the mainstream. However, in terms of installation space, cost, and environmental load reduction, thinner disk storage cases such as 5 mm and 7 mm are also available. It has come to be used. In such a thin disc storage case, the width of the side surface of the storage case is small, and it is difficult to display a title or the like with a sufficient size even if a side index is attached. Actually, a thin disk storage case such as 5 mm thickness or 7 mm thickness provided with a side index has not been put into practical use.

  The user can quickly select the desired disc storage case from a plurality of disc storage cases that are stored in a shelf, etc., so that the title is displayed in a sufficiently large size even in a thin disc storage case. A side index is preferably attached.

Under such circumstances, Patent Document 2 proposes that the side index surface is wider than the thickness of the storage case by arranging the side wall on the connecting side of the storage case obliquely to ensure a wide side index surface. Has been.
Japanese Patent Laid-Open No. 10-106203 JP 2001-106281 A

  However, in the disk storage case described in Patent Document 2 in which the side wall on the connection side of the storage case is disposed obliquely, an acute angle portion (see FIG. 2 in Patent Document 2) is formed on the connection side of the pair of case halves. Therefore, this part is easily damaged and sufficient strength cannot be obtained. Moreover, when stored side by side on a shelf or the like, the side walls arranged obliquely are located in the forefront and exposed to the user side, so the aesthetics are not good.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a disk storage case that has a sufficient side index surface regardless of the thickness of the disk storage case, and that has good strength and aesthetics. Is.

A disc storage case according to the present invention includes a disc tray that detachably holds a recording medium disc, and a pair of case halves that accommodate the disc tray and that are connected to each other at one end and can be opened and closed. In case
At least one of the case halves has a plate-like main body facing the disk tray and a side wall connected to the plate-like main body, and a main index facing the plate-like main body and a sub-face facing the side wall. A folded index card comprising an index is attached, and the case half supports the secondary index of the index card, and the secondary index is arranged obliquely with respect to the primary index. An index support portion is provided to define the following.

  In the disc storage case of the present invention, the index support portion protrudes from the inner surface of the plate-like main body and / or the inner surface of the side wall of the one case half, supports the sub index, and the sub index. It is preferable to have an inclined surface that defines an inclination angle with respect to the main index.

  As the index support portion, a rib-like member protruding from the inner surface of the plate-like main body and / or the inner surface of the side wall, or a part of the plate-like main body and / or the side wall is formed in an embossed shape. A protrusion is preferred.

  The inclination angle of the secondary index with respect to the main index is preferably larger than 90 °.

  In the disc storage case of the present invention, at least one case half has a plate-like main body facing the disc tray and a side wall connected to the plate-like main body. A folded index card composed of opposing secondary indexes is attached, and the case half supports the secondary index of the index card, and the secondary index is arranged obliquely with respect to the primary index. The index support part to prescribe | regulate is provided.

  In such a disc storage case, the secondary index, which is a side index, can be arranged obliquely with respect to the main index due to the presence of the index support part, and the inclination angle can be freely designed, so the width of the side index can be stored in the storage case. It can be set to a desired value larger than the thickness. Therefore, in the disc storage case of the present invention, a sufficient side index surface is ensured even in a thin storage case such as a thickness of 5 mm or 7 mm regardless of the thickness of the disc storage case.

  Further, in the disk storage case of the present invention, the above effect can be obtained without making the side wall of the case half slant. Therefore, unlike the storage case described in Patent Document 2, an acute angle portion is not formed on the appearance and the strength is increased. And the aesthetics are also good.

It is a partial expanded sectional view (BB 'sectional drawing). 6A is a left side view of FIG. 3, and FIG. 6B is a right side view of FIG. The recording medium disk and the index card are omitted as appropriate.

  As shown in FIG. 1, a disc storage case 1 of this embodiment includes a disc tray 10 that detachably holds a recording medium disc 2, and an openable front case half 20 and a back case that accommodates the disc tray 10. A half body 30 is schematically configured. The pair of case halves 20 and 30 are disposed to face each other via the disc tray 10 and the left back end portions (one end portions) in the drawing are connected to each other. Also, the disc tray 10 is detachably fitted into the back case half 30 of the pair of case halves.

  Each of the disc tray 10 and the case halves 20 and 30 for storing the disc tray has a substantially rectangular shape in plan view, and these are made of the same or non-identical resin, and the color and pattern are arbitrary. However, at least the case halves 20 and 30 preferably have translucency in consideration of index visibility.

  The front-side case half 20 is generally configured by a plate-like main body 21 that faces the disc tray 10 and a pair of side walls 22 that extend in the loading / unloading direction X (details will be described later) of the front-side index card 41. Reference numeral 22 denotes a connecting arm 22 a that is wider than the plate-like main body 21, and the wide portion is connected to the back case half 30.

  The back-side case half 30 is roughly constituted by a plate-like main body 31 facing the disc tray 10 and a pair of side walls 32 parallel to the side walls 22. In order to easily remove the disc tray 10 from the back case half 30 by placing a finger on the disc tray 10, each of the pair of side walls 32 is provided with a notch 32 a at a substantially central portion.

  In the case halves 20 and 30, the area of the plate-like main bodies 21 and 31 is designed so that the side wall 22 of the front case half 20 is positioned outside the side wall 32 of the back case half 30. As shown in FIG. 2A, the back case half 30 is fitted into the front case half 20.

  Projections 22b project from the inside of the pair of connecting arms 22a forming the front case half 20, and recesses 32b into which the tips of the projections 22b enter are provided outside the pair of side walls 32 forming the back case half 30, respectively. The pair of case halves 20 and 30 are connected to each other so as to be openable and closable with the pair of protrusions 22b as pivot axes. This end portion is referred to as a “connection side end portion” and is denoted by reference symbol E, and an end portion (right front end portion and other end portion in the drawing) opposite to the connection side is denoted by reference symbol F (see FIG. 2A). .

  The disc tray 10 is mainly configured by a tray main body 13 having a substantially disc-shaped disc accommodating recess 11 in which the recording medium disc 2 is fitted and accommodated, and an overhanging portion 12 extending outside the disc accommodating recess 11. ing. A disc clamper 11 a that detachably holds the central opening side of the recording medium disc 2 is provided at the center of the disc receiving recess 11.

  From the overhanging portion 12 located on the connection side of the pair of case halves 20 and 30, a side wall 14 a directed to the front case half body 20 side and the side wall 14 a are connected to and parallel to the surface of the overhanging portion 12. A substantially L-shaped portion 14 in cross section, which is formed of a flat portion 14b, is extended. The flat portion 14b is placed between the pair of connecting arms 22a so as to be flush with the plate-like main body 21 of the front case half 20 when the pair of case halves 20 and 30 are closed.

  A front-side index card 41 and a back-side index card 42 are interposed between the front-side case half 20 and the disc tray 10 and between the back-side case half 30 and the disc tray 10, respectively. The index cards 41 and 42 are printed with, for example, a title, recorded content, a photograph, a field in which the recorded content can be rewritten, and the like of the recording medium disc 2. In the present embodiment, the back side index card 42 includes a side index for displaying a title or the like.

  As shown in FIG. 3, each of the pair of side walls 22 constituting the front case half 20 has a substantially semicircular hooking piece 24 for hooking and holding the front index card 41 parallel to the surface of the plate-like main body 21. There are three protruding points. As shown in FIG. 1, the connection side end E of the front case half 20 and the end F on the opposite side are both open without side walls, and the front index card 41 is open from either of the ends E and F. It is supposed to be accessible. The front-side index card 41 is preferably inserted / extracted from the end F side (the in / out direction X in this case is illustrated). The overhanging portion 12 of the disc tray 10 is provided with a concave portion 12a into which the retaining piece 24 enters.

  As shown in FIG. 1, the back case half 30 has side walls 33 and 34 at the connection side end E and the opposite end F, respectively. The back-side index card 42 is a folded index card including a main index 42 a that faces the plate-like main body 31 of the back-side case half 30 and a secondary index 42 b that faces the side wall 33. In the present embodiment, the secondary index 42 b is a side index that is visually recognized from the side surface side of the storage case 1.

  In the present embodiment, as shown in FIGS. 1 to 3 and 5, the back case half 30 supports the secondary index 42 b of the back side index card 42, and the secondary index 42 b is disposed obliquely with respect to the main index 42 a. A rib-like member 35 (index support portion) is provided to define the above.

  The rib-shaped member 35 is a member that is attached to the corner portion formed by the plate-shaped main body 31 and the side wall 33 in contact with the plate-shaped main body 31 and the side wall 33. That is, the rib-like member 35 is a member protruding from the inner surface of the plate-like main body 31 and the inner surface of the side wall 33. The rib-like member 35 is a substantially triangular plate-like member that supports the secondary index 42b and has an inclined surface 35a that defines an inclination angle α of the secondary index 42b with respect to the main index 42a. Two rib-like members 35 are provided at both ends of the side wall 33 in total. The formation location and number of rib-shaped members 35 can be designed as appropriate.

  In the present embodiment, as shown in FIG. 5C, since the secondary index 42b is disposed along the inclined surface 35a of the rib-like member 35, the secondary index 42b is disposed obliquely with respect to the main index 42a. In the present embodiment, the inclination angle α of the secondary index 42b with respect to the main index 42a can be freely designed by adjusting the inclination angle of the inclined surface 35a of the rib-like member 35. In the present embodiment, the inclination angle α is an obtuse angle (> 90 °).

  In the present embodiment, the secondary index 42b, which is a side index, can be arranged obliquely with respect to the main index 42a, and the inclination angle α can be freely designed, so that the width of the side index is larger than the thickness of the storage case 1. A desired value can be obtained.

  The width of the secondary index 42b (side index) increases as the inclination angle α of the secondary index 42b with respect to the main index 42a deviates from 90 °.

  Specific examples of dimensions are given below. For example, when printing M characters (about 3.5 mm height) by King Jim's “Tepla (registered trademark)”, the margin of the side index surface is set to 1 mm, and the minimum necessary width of the secondary index 42b is about 4.5 mm. In the case of a thin case having a case thickness of 5 to 7 mm, for example, by setting α = 95 to 165 °, a sufficient side index surface can be secured.

  In the present embodiment, since the inclination angle α of the secondary index 42b with respect to the main index 42a is an obtuse angle (α> 90 °), the index card 42 can be easily put in and out, which is preferable. However, the inclination angle α may be an acute angle (<90 °). Also in this case, the side index surface becomes larger as the inclination angle α deviates from 90 °. For example, as shown in FIG. 5 (d), the rib-shaped member 35 protrudes from the side wall 33 so that the inclined surface 35 a of the substantially triangular rib-shaped member 35 faces the plate-shaped main body 31, whereby the inclination angle α Can be an acute angle.

  The disc storage case 1 of the present embodiment is configured as described above.

  In the disk storage case 1 of the present embodiment, the back case half 30 has a plate-like main body 31 and a side wall 33 connected to the plate-like main body 31, and a main index 42 a and a side wall facing the plate-like main body 31. A bent index card 42 composed of a secondary index 42b facing 33 is attached to the case half 30 to support the secondary index 42b of the index card 42, and the secondary index 42b is the primary index 42a. Are provided with rib-like members 35 (index support portions) which are defined so as to be disposed obliquely.

  In such a disk storage case 1, the presence of the rib-like member 35 allows the secondary index 42b, which is a side index, to be disposed obliquely with respect to the main index 42a, and the inclination angle α can be freely designed. Regardless of the thickness of 1, even a thin storage case such as 5 mm thickness or 7 mm thickness can secure a sufficient side index surface.

  In the present embodiment, the above-described effect can be obtained without making the side wall 33 of the back case half 30 slanted. Therefore, unlike the storage case described in Patent Document 2, an acute angle portion is not formed on the appearance, and the strength and aesthetics are improved. The property is also good.

  In the present embodiment, the rib-like member 35 is provided on the plate-like main body 31 and the side wall 33 of the back-side case main body 30. However, by providing the rib-like member 35 on the plate-like main body 31 and / or the side wall 33, An effect is obtained.

The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The basic configuration of the disk storage case 3 of this embodiment is the same as that of the first embodiment, but the support structure of the secondary index 42b of the back side index card 42 is different. Specifically, in the first embodiment, the rib-like member 35 is provided on the back case half 30 as an index support portion for supporting the secondary index 42b, whereas in the present embodiment, as shown in FIG. A projecting portion 36 that is projected and formed in an embossed shape is provided on a part of the plate-like main body 31 of the back-side case half 30. The projecting portion 36 extends along the side wall 33, has an inclined surface 36a that supports the secondary index 42b and defines an inclination angle α of the secondary index 42b with respect to the primary index 42a. The formation length and the number of the protrusions 36 can be designed as appropriate.

  As shown in FIG. 7B, also in this embodiment, the secondary index 42b is arranged along the inclined surface 36a of the protrusion 36, and the secondary index 42b is arranged obliquely with respect to the main index 42a. Also in the present embodiment, the inclination angle α of the secondary index 42b with respect to the main index 42a can be freely designed by adjusting the inclination angle of the inclined surface 36a of the protrusion 36. Also in the present embodiment, the inclination angle α is preferably an obtuse angle (> 90 °) in consideration of the ease of entering and exiting the index card 42.

  The disc storage case 3 of the present embodiment is configured as described above.

  The disc storage case 3 of the present embodiment supports the secondary index 42b of the index card 42 on the plate-like main body 31 of the back case half 30 and the secondary index 42b is arranged obliquely with respect to the primary index 42a. An embossed protrusion 36 is provided as an index support part to be defined.

  In the present embodiment, as in the first embodiment, the above-described effect can be obtained without making the side wall 33 of the back case half 30 slant. Therefore, unlike the storage case described in Patent Document 2, there is an acute angle portion on the appearance. It is not formed and has good strength and aesthetics.

  In this embodiment, although the case where the embossed protrusion part 36 was provided in the plate-shaped main body 31 of the back side case main body 30 was demonstrated, by providing the embossed protrusion part 36 in the plate-shaped main body 31 and / or the side wall 33, Similar effects can be obtained.
