BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a sheet for holding information recording carriers, which is used for containing, pigeonholing and storing information recording carriers which are in the form of small thin plates, such as floppy disks and CD-ROM disks. More particularly, the present invention relates to a sheet for holding information recording carriers, which is mainly made of a synthetic resin such as ABS resin, which is suited for being stored in binders and cabinets.
BACKGROUND ART
With the recent progress of information-oriented society, electronic equipment such as various computers and word processors, which deal with characters, symbols and graphic information are now widely used in various fields.
As media for recording characters, symbols and graphic information, which are used with such electronic equipment, information recording carriers such as floppy disks, CD-ROM disks and the like that magnetically record the information, are often used. This is because floppy disks, CD-ROM disks and the like have large memories, and each disk is small and thin so that ease of handling of the disk is good.
For pigeonholing and storing information recording carriers such as floppy disks, a holding sheet as disclosed in Japanese Patent Publication (Kokoku) Nos. 4-5369 and 4-5977 is conventionally used.
This holding sheet basically comprises one synthetic resin sheet; a binding margin formed on one side edge of the synthetic resin sheet, which has a plurality of binding holes; a plurality of rectangular cavities for holding information recording carriers, which are formed in the surface of the synthetic resin sheet; and a pressing strip for holding the information recording carrier, which extends from a side wall of each of the rectangular cavity into the inner region of the cavity. To ensure ease of insertion and removal of the disks, reliability of holding and sufficient strength of the holding sheet, improvements are made, such as providing the bottom plates of the rectangular cavities with pillar portions, making the cut holes small, and forming guide portions for guiding the information recording carriers.
There is also a conventional holding sheet as disclosed in Japanese Laid-open Utility Model Application (Kokai) No. 5-84676, in which the portions for holding floppy disks are formed on both sides of the sheet such that the portions are rotatably mounted so as to enable removal of the disks from one side, and in which hanging members for hanging the sheet in a cabinet are provided, that are mounted on the upper portions of both sides of the sheet and that can be drawn out from the sheet.
However, with the above-mentioned conventional sheets for holding information recording carriers, there is no measure for identifying each floppy disk at a glance when the holding sheets are stored in a binder or are stored in a cabinet by hanging. Therefore, it is troublesome to identify each floppy disk (information recording carrier) when a floppy disk is to be taken out. Further, the conventional information recording carries have drawbacks in that their structures are complicated, forming the sheets by molding is troublesome, and costs for producing the sheets are high.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a sheet for holding information recording carriers that overcomes such drawbacks of the conventional sheets for holding information recording carriers, that has indices which enable a person to easily find the desired information recording carrier such as a floppy disk held in the sheet.
Another object of the present invention is to provide a sheet for holding information recording carriers, that has a simple structure, that may be formed by injection molding in which the mold is moved only in one direction, that are easy to produce and suited for large scale production, and with that the production cost is small.
Still another object of the present invention is to provide a sheet for holding information recording carriers, which may be con
