Description

  The present invention relates to a plurality of recorded disks that are stored and stored in a stacked state in a disk storage case by entering a serial number or a heading of recorded contents of each disk. The present invention relates to an index label for a laminated disk that allows a desired disk to be searched at a glance from the outside even though the disk is stored in a laminated state.

  Conventionally, as a case for storing a plurality of discs such as a compact disc (CD-R) and a digital video disc (DVD) in a stacked state, for example, as described in Patent Document 1, the diameter is larger than that of the disc. On a plurality of discs stacked on the bottom plate, with a pillar body with a fixed diameter smaller than the center hole (chucking hole) of the disc at the center of the disc-shaped bottom plate It is widely known that it has a structure with a transparent frustoconical cover that can be removably attached to the bottom plate or the upper end of the column, but a plurality of recorded disks are placed in this storage case. When stored in a stacked state, the other disks except the uppermost disk are in a state where only the outer peripheral end face is exposed to the outside. It is difficult to attach an index sticker that can recognize information such as music or video recorded on each disc on the outer peripheral end surface, and therefore, titles or headings etc. are printed or handwritten on the surface on which no information is recorded. Is currently displayed.

On the other hand, in a floppy disk that magnetically records information, as described in Patent Document 2, information recorded on the floppy disk is displayed on a flat rectangular holder that houses a single floppy disk. A case is known in which a protruding part is projected outward and a plurality of holders are stored in a stacked state.
Japanese Patent Laid-Open No. 11-349084 JP-A-4-253678

  In the former case where compact discs and other discs are stored in a stacked state, it is not possible to directly check the disc from the outside in order to search for the disc storing the desired information. It is necessary to search for the heading, etc., which is addressed to the top layer from the top layer, and check the headings etc. written on the top surface one after another. However, there is a problem that even if each recorded information is sequentially stacked in an orderly arranged state, the organized state cannot be recognized at a glance from the outside.

  On the other hand, as in the latter case, if a holder is provided in the holder for storing the disc, the desired disc can be found directly from the outside without removing the disc from the holder, but the disc is stored in the holder. Therefore, not only does the number of discs that can be accommodated in the case decrease, but also a separate holder is required, which is expensive and uneconomical.

  Therefore, like the former disc storage case, a plurality of blank discs before writing are stored in a stacked state, information is recorded on each disc, and then these discs are stacked again in this storage case. Although it is desirable to keep it in a state, an index label or a piece of paper is stuck on the outer periphery of the disk so that the desired disk can be searched directly from the outside and protruded from the disk. There is a problem that it cannot be used.

  The present invention has been made in view of such problems, and the object of the present invention is to provide a support that is laminated on the bottom plate of a commercially available case and has a central hole protruding from the center of the bottom plate. With respect to the discs stored in the case in the inserted and held state, description items such as numbers and headings that organize information recorded on each disc can be easily searched from the outside. It is in providing a label for indexing laminated discs.

In order to achieve the above-mentioned object, the index label of the laminated disk of the present invention, as described in claim 1, has a disk-shaped bottom plate projecting a vertical column in the center part upward, An index label for a plurality of recorded disks stacked on the bottom plate in a state where the center hole is inserted into the support body in a disk storage case comprising a cover that is detachably covered on the bottom plate An index piece that protrudes outward from the outer peripheral end face of the disk and can be bent in the stacking direction of the disk is provided at an end of the label main body provided with an engagement hole to be inserted into the support rod . In addition, the index piece portion has a structure in which a notch locking portion that is engaged with the other side end surface of the index piece portion of the label main body is provided on one side portion of the proximal end of the index piece portion .

  In the index label of the laminated disk configured as described above, the invention according to claim 2 is that the label main body is formed of a rectangular paper piece that is long in the radial direction of the disk, and has one end portion in the length direction as a base end portion. An engagement hole is provided at the base end portion and an index piece portion is provided at the tip end portion, and the adjacent label main body is opposed to the both end portions of the base end of the index piece projecting from the outer peripheral end surface of the disk. It has a structure in which a notch locking portion is provided for engaging the side end portions with each other so as to be detachable.

  On the other hand, in the invention according to claim 3, the label main body is formed of a circular sheet having the same size and shape as the disk, and an engagement hole is provided at the center thereof, and an index piece is provided at a part of the outer peripheral end, Furthermore, as a structure in which notch locking portions are provided on both side end portions of the base end of the index piece protruding from the outer peripheral end surface of the disc so that the opposing side ends of the adjacent label main bodies can be engaged with and disengaged from each other. Yes.

  Further, in the invention according to claim 1, claim 2 or claim 3, the invention according to claim 4 is characterized in that the index main part of the label main body is formed in a horizontally long rectangular shape having a width of about 30 mm, and a notch It is characterized in that the vertical width when bent through the locking portion is about 10 times the thickness of the disc.

  According to the first aspect of the invention, the label main body of the index label is provided with the engagement hole that is removably inserted into the vertical column that projects from the center of the bottom plate of the case that stores the discs in a stacked state. In addition, since the end protruding from the outer peripheral end of the disc is formed in the index piece, the disc on which information is recorded is attached to the column body that has a hole provided in the center thereof protruding on the bottom plate of the case. The disc is inserted from above and stacked on the disc loaded on the bottom plate via the index label on which the reference number has already been written, and recorded on the disc at the tip index piece of the new index label. Enter the matters such as the reference number of the information and the like, search terms, heading phrases, symbols, etc., and insert the engagement hole provided in the base end portion of this index label into the column body of the storage case. Place on disc Thus, the index piece portion can be automatically and accurately projected from the outer peripheral surface of the disc, and in this state, the index piece portion is bent in the vertical direction along the outer peripheral end surface of the disc. This makes it possible to clearly display the description items such as the reference number and the search term phrase described in the index piece outward and to search at a glance without removing the desired disc from the case. .

Further, as described above, a disc on which information is recorded and an index label in which a search term phrase or the like of the information recorded on this disc is written on the index piece are sequentially provided along the support on the bottom plate of the case. In a state where a plurality of sheets are stacked, the label main body is sandwiched between vertically adjacent disks, and the engagement hole provided at the base end portion is inserted and locked into the support column of the case, so that the space between the disks The index piece at the tip of the index piece can be accurately displayed outward, and the index piece of the label main body adjacent to one side of the base end of each index piece. Since the notch locking portion to be engaged with the other side end surface is provided, each index label is horizontal while being in sliding contact with the disk surface with the engaging hole being locked in the inserted state. in particular it is rotated in the direction Up and down can be arranged in the circumferential direction while engaging the shaped abutting the opposite end face to each other an index piece portion adjacent, therefore, the disc on to all of the disk that records information The index strips of the index labels arranged in the above can be arranged in parallel in the circumferential direction so that the disk can be easily and reliably searched from the outside.

  In addition, since the label main body can be formed of a thin piece of paper, it is possible to stack a plurality of discs in the case without bulking and scratching the discs. When a desired disk on which information is recorded is taken out from the storage case, the disk loaded above the index label of the disk disposed on the disk is moved upward along the support column of the case. The target disc can be easily displayed on the uppermost layer by pulling it out, and in this state, the disc can be easily taken out from the case together with the index label. Further, the storage of the disk recorded above can be stored in a compact manner by reusing a commercially available case having the above-described configuration, and the disk can be easily organized.

  According to a second aspect of the present invention, the label main body is formed of a rectangular paper piece that is long in the radial direction of the disk, and an engagement hole is formed in the base end portion with one end portion in the length direction serving as a base end portion. In addition, an index piece is provided at the front end, and the opposite side ends of the adjacent label main bodies are engaged with and disengaged from the both ends of the base end of the index piece protruding from the outer peripheral end surface of the disc. Since the notch locking part to be freely engaged is provided, the label main body made of a rectangular paper piece is easy to handle, and the engagement hole provided in the base end part can be easily fitted into the column of the case. A notch mechanism in which the index pieces protruding from the discs in the upper and lower index labels respectively provided on the upper and lower adjacent discs are provided on the opposite end surfaces of the upper and lower adjacent discs. Engage stop This ensures that the index piece of the lower index label is not accidentally covered by the index piece of the upper index label, and the index pieces of all the index labels are attached to the laminated disc. It can be arranged accurately and orderly in the circumferential direction along the outer peripheral surface, and the search can be easily and accurately performed.

  According to the invention of claim 3, since the label main body is made of a circular sheet of the same size and shape as the disk, the engagement hole provided at the center thereof is fitted into the support column of the case so as to be within the case. The entire surface of each stacked disk can be protected to prevent the surface of the disk from being scratched or soiled, and an index piece is provided at a part of the outer periphery of the disk. Since the notch locking part which engages the opposite side edge parts of an adjacent label main body mutually is releasably provided in the both ends of the base end of this index piece part which protrudes from the peripheral end face of the above-mentioned claim As in the index label described in 2, the index piece of the lower index label is engaged with the index piece of the upper index label by engaging the notch engaging portions provided on the opposite end surfaces thereof The part is unexpectedly covered The index strips of all the index labels can be arranged accurately and orderly along the outer circumferential surface of the laminated disk in the circumferential direction, and the search can be performed easily and accurately. it can.

  Moreover, according to the invention which concerns on Claim 4, while forming the index piece part of the label main body of the said Claims 1-3 in the horizontal oblong shape whose horizontal width is about 30 mm, via a notch latching | locking part Since the vertical width when bent is about 10 times the thickness of the disk, the index labels arranged on each disk stacked in the case are engaged with the notch locking portions facing each other. When they are juxtaposed in the circumferential direction while being engaged with each other, the distance between the index piece portions of the index labels adjacent in the circumferential direction is gradually and gradually displaced stepwise by a height corresponding to the thickness of one sheet. When a plurality of index pieces that are raised in a spiral and are circumferentially engaged with each other make one round of the disk, the thickness of the disk is 1 mm and the diameter is 12 cm. The index piece of the label for the label is more than the top and bottom width. Height at which only can be placed in a state in which it is located above.

  Therefore, even if a large number of recorded discs of several tens or more are stored in the case, the index strips of the index labels arranged on each disc are spirally stepped around the disc. Thus, all index pieces can be clearly recognized from the outside, and the target disk can be searched quickly and reliably.

  If a plurality of the above-mentioned index labels are laminated and the base end of the label main body is bound and peeled with an adhesive or the like, the index is recorded each time the disc on which information is recorded is stored in the disc storage case. By putting a number for organizing the information recorded on the index piece and separating it from the bundle of labels for use, or by entering a search symbol, it can be immediately placed on each disk. If a plurality of discs on which information has already been recorded are stored in a stacked state in the case, all these discs can be arranged so that they can be easily searched from the outside. it can.

  Next, a specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an index label A, FIG. 2 is a perspective view of a state in which a plurality of index labels A are bound, and FIG. FIG. 2 is a perspective view for explaining a use state, in which an index label A is a radius of an optical disc (hereinafter simply referred to as a disc D) such as a compact disc (CD-R) or a digital video disc (DVD) ( 60 mm) at one end (hereinafter referred to as the base end) in the length direction of the label main body 1 made of a rectangular paper piece that is shorter than the diameter and at the center of the bottom plate 11 in the disc storage case 10 described later. Engagement holes 2 are provided so as to be removably inserted into a column stacking column 12 projecting vertically upward, and a label main body 1 is disposed in the column 12 together with the disc D in a stacked state. When Are formed in the label main body 1 of the distal end portion of the housing case 10 and outer peripheral edge surfaces foldably vertically along the indexes pieces of the disk D are stacked in a three projecting outwardly from the disk D which definitive.

  Specifically, the index label A has a length of the label main body 1 of 90 mm, a width of 30 mm, and the diameter of the engagement hole 2 is the same as or slightly larger than the center hole (chucking hole) of the disk D. 16 mm, the length of the index piece 3 is about 10 mm, which is several times the thickness of the disk D, and the width direction of the label main body 1 from the both end faces to the base end of the index piece 3 The notch locking portions 4 and 4 ′ are formed with a depth of about 3 to 5 mm toward the central portion and an opening width in the length direction of the label main body 1 of about 2 to 3 mm. In these notch locking portions 4 and 4 ′, the notch locking portion 4 formed on one end side of the label main body 1 has a U-shape in which the vertical width of the opening end is about 3 mm and the width on the back side is about 2 mm. On the other hand, the notch engaging portion 4 ′ formed on the other end side of the label main body 1 is formed in a lateral V shape with an opening end having a vertical width of 2 mm. A crease 5 that can be bent along the outer peripheral end surface of the disk D is formed between the upper end edges of the U-shaped notch locking portion 4.

  As described above, since the U-shaped notch locking portion 4 and the laterally V-shaped notch locking portion 4 ′ are formed at the base end of the index piece 3 of the label main body 1, as described later, In the storage case 10, index labels A and A are arranged on adjacent disks D and D that are vertically overlapped, and the index pieces 3 and 3 protruding from the disk D are bent downward and circumferentially with respect to each other. When the notch locking portions 4 and 4 'of the index labels A and A facing each other in the state of being arranged side by side are engaged, the index piece portion 3 of the index label A disposed on the upper side is on the lower side. The notch locking portions 4 are configured to be locked with the index piece portion 3 of the index label A arranged being displaced upward by the thickness of one disk D. 4 'may be formed into a shape that can be locked to each other other than the U-shape or the lateral V-shape. There.

  In addition, as shown in FIG. 2, the index label A configured in this way is a plurality of stacked labels, and the base end portion of the label main body 1 of all the index labels A is adhesive or adhesive. It is preferable that it is configured such that it can be peeled and bundled in order to be peeled off one by one.

  On the other hand, the storage case 10 storing the laminated disk D for enabling sorting and searching by the index label A is a generally known commercially available case. For example, FIG. 3 and FIG. As shown in FIG. 2, the bottom plate 11 is made of a hard synthetic resin having a disk shape larger than the disk D, and has a fixed length (height) projecting vertically upward from the center of the bottom plate 11. A support body 12 made of hard synthetic resin, and a plurality of laminated disks D stacked on the bottom plate 11 with the center hole d (chucking hole) inserted through the support body 12 and covering the top plate 11 And a cover 13 made of a transparent synthetic resin formed in a truncated cone shape so as to be detachably mounted on the cover.

  In the figure, a support column 12 is integrally provided at the center of the bottom plate 11, and the cover 13 has an opening end surface at the lower end thereof received by the upper surface of the outer peripheral end portion of the bottom plate 11, and The outer peripheral surface of the protrusion 11a projecting in an arc shape along the inner peripheral surface of the cover 13 on the upper surface of the outer peripheral end of the bottom plate 11 with the locking piece 13a projecting inward on the inner surface The horizontal engagement groove 11b formed at the lower end is detachably locked so as to be removable, but a screw portion is formed at the distal end portion of the column body 12, while the top plate portion of the cover 13 is formed. A hole through which the screw portion is inserted is formed in the center, and a cover 13 is placed on the bottom plate 11, and a nut is screwed onto the screw portion in a state where the upper end screw portion of the column 12 is projected from the hole. It may be a commercially available case in which the cover 13 is configured to be removable. The case may be configured such that it is formed separately and its lower end is detachably erected and fixed to the center of the bottom plate 11.

  In the above embodiment, the shape of the label main body 1 of the index label A is formed in a rectangular shape, but the index label A ′ shown in FIG. 4 has the same size and shape as the disk main body 1 ′. An engagement hole 2 is formed by a circular sheet, and is detachably inserted in the central portion of the bottom plate 11 in the disc storage case 10 and is detachably inserted into the disc stacking column body 12 projecting vertically upward. In addition, an index piece portion 3 having the same shape and the same structure as the rectangular index label A is projected outwardly at a part of the outer peripheral end.

  The circular label main body 1 'is formed to have the same diameter as the disc D, and is provided at the base end of the index piece 3 at the base end of the rectangular index label A. The index piece 3 having the same shape and the same structure as the cutout locking portions 4 and 4 'is provided. In this case, since the label main body 1 ′ is formed in a circular shape, the inner edge of the U-shaped notch locking portion 4 and the lateral V-shaped notch locking portion 4 ′ on the side of the label main body 1 ′ are connected. Is formed by the peripheral end surface of the label main body 1 ', and the crease between the leading ends of the notch locking portions 4 and 4' can be bent along the outer peripheral end surface of the disk D. The index piece portion 3 is formed in a horizontally long rectangular shape having a horizontal width of 30 mm and a vertical width of about 10 mm, similar to the index piece portion 3 in the rectangular index label A. The shapes of the locking portions 4 and 4 ′ may be formed in shapes that can be locked to each other other than the U-shape or the lateral V-shape.

  Next, the usage mode of the index labels A and A ′ will be described. After the disc D on which information such as music and video is recorded is stored in the commercially available storage case 10, the disc D is stored on the disc D. For indexing in which the index number for organizing the information recorded in D, the heading term phrase of information, or the symbol 6 for searching (hereinafter referred to as indexing item 6) is described in the index piece 3 Overlay label A or A '. Storage of the disk D in the storage case 10 is performed by inserting the center hole d through a column 12 standing upward from the center of the case bottom plate 11 and storing the recorded disk previously stored. This is performed by superimposing the index items 6 of the disk D on the D via the index label A or A ′ described in the index piece 3.

  Similarly, the engagement hole 2 provided at the base end of the label main body 1 or 1 ′ of the index label A or index label A ′ in which the index items 6 of the disk D are written in the index piece 3 is provided. When placed on the disk D while being inserted through the column body 12, the index piece 3 projects outward from the outer peripheral end surface of the disk D. After that, when the index piece 3 of the index label A or A ′ is bent downward along the outer peripheral end surfaces of several upper disks in the disk D laminated on the bottom plate 11 of the storage case 10, The index items 6 written on the index piece 3 are directed outward.

  Next, the index label A or A ′ is rotated in the circumferential direction on the disk D around the support body 12 of the storage case 10 so that one end surface of the index piece 3 is positioned ahead of the disk D. The notch locking portions 4 and 4 ′ of the index pieces 3 and 3 are engaged with each other while being brought into contact with the other end surface of the index piece 3 of the index label A or A ′ on the disk D stored in the disk D. The opposite bottom ends of these notch locking portions 4 and 4 'are abutted in a crossing manner. Then, the index strips 3 and 3 of both index labels A, A or A ′ and A ′ are parallel to each other in the circumferential direction while being prevented from moving in the overlapping direction, and the lower index label A or The upper index label A or A ′ with respect to A ′ is displaced stepwise upward by the thickness of the disk D.

  In this way, the disk D in which information is recorded in the storage case 10 and the index label A or A ′ in which the index items 6 of the disk D are written on the index piece 3 are sequentially laminated to a plurality of sheets, Notch locking portions facing each other in the state in which the index pieces 3, 3 facing in the circumferential direction of the index labels A, A, or A ', A' adjacent vertically are folded downward as described above. As shown in FIG. 6, the index labels A, A or A ′, A ′ of the index labels 3 and 3 adjacent to each other in the upper and lower directions are sequentially turned in the circumferential direction. The index piece 3 of the upper index label A or A ′ is higher in height than the index piece 3 of the lower index label A or A ′. It is arranged in a spiral while being displaced stepwise only upward. Therefore, the index strips 3 of all the index labels A or A ′ are presented entirely outward, that is, in an outer diameter direction perpendicular to or intersecting with the length direction of the support column 12 of the storage case 10. Thus, the disk D corresponding to the index item 6 described in the index piece 3 can be recognized at a glance from the outside.

  Furthermore, since the width of the index piece portion 3 of each index label A or A 'is about 30 mm and the length is about 10 times the thickness of the disk D, a plurality of sheets arranged in parallel in a spiral step shape in the circumferential direction The index piece 3 of the index label A or A ′ on the uppermost layer corresponds to the vertical width of the index piece 3 while the disk D is rotated once by the index piece 3 of the index label A or A ′. It will be in the state displaced upwards more than height. Therefore, even if several dozen to 100 discs D are stacked in the storage case 10 with the index labels A or A ′ arranged on each disc D, all the index labels A or A ′ are stacked. The index piece portions 3 can be arranged in a spiral staircase shape around the disk D with the display surface exposed to the outside entirely.

  As described above, when a large number of discs D on which information is recorded are stored on the bottom surface 11 of the storage case 10 in a state of being stacked via the respective index labels A, and covered with the transparent cover 13. The index piece 3 of all index labels A or A ′ can be directly viewed from the outside through the transparent cover 13, and the desired disc D can be easily and reliably searched by the index piece 3. At the same time, by removing the cover 13 and extracting the disk D above the disk D from the support body 12, or by including the disk D so that the disk D becomes the lowest layer, the desired disk can be easily obtained. The disk D can be taken out from the storage case 10.

  Although the index piece 3 of the index label A or A ′ disposed on each disk D is bent downward, the index piece on the lower disk D stacked on the bottom plate 11 of the storage case 10 3 is not only difficult to bend downward due to the presence of the bottom plate 11, but is also concealed by the ridge 11 a protruding from the upper surface of the outer peripheral end of the bottom plate 11 in order to lock the cover 13. It becomes impossible to look directly from the outside. In order to solve this problem, as shown in FIG. 7, before storing the disk D in the storage case 10, a ring-shaped spacer 14 having a thickness of about 10 mm is inserted into the support column 12 of the storage case 10. The disc D recorded on the bottom plate 11 is placed on the central portion of the bottom plate 11, and then the disc D recorded on the bottom plate 11 is sequentially stacked and stored together with the index labels A and A 'arranged on the upper surface thereof. Yes.

  Therefore, a space portion having a height corresponding to the vertical width of the index piece portion 3 of the index labels A and A ′ is provided between the outer peripheral end of the lowermost disk D and the bottom plate 11 of the storage case 10. The index piece 3 can be bent downward and can be clearly presented to the outside. The ring-shaped spacer 14 can be used as a disk presser provided in a commercially available disk storage case.

Further, the index label A or A ′ has a label main body 1 or 1 ′ formed in a rectangular shape or a circular shape, but is provided with an engagement hole 2 at the base end portion and an index piece portion 3 at the tip end portion. As long as the structure is the same, it may be formed in any shape. Furthermore, the notch locking portions 4 and 4 'are formed on both sides of the base end portion of the index piece portion 3, but the notch locking portions are not provided on both sides, but only on one side, that is, only one. The notch locking portion may be engaged so as to mesh with the straight other end surface of the index piece portion 3 of the adjacent index label A or A ′ .
