[Industrial applications]

 The present invention relates to a binder type mini disk holder suitable for binding and storing a mini disk in a so-called system notebook.

[0002]

[Prior art]

 In recent years, storage carriers such as floppy disks, compact disks, and mini disks have become widespread, and various cases for storing this type of storage carrier have been proposed. For example, in Japanese Utility Model Laid-Open No. 60-176640, a large number of storage cases for storing compact disks are arranged side by side in a rack body in the shape of a substantially rectangular parallelepiped box having an open front surface. A storage case for a compact disc has been proposed in which a desired storage case is rotated and pulled out when the compact disk is taken out by pivotally supporting the lower corners of the. In addition, mainly for holding a floppy disk in a thin holder in consideration of convenience when carrying, for example, in Japanese Utility Model Laid-Open No. 5-44891, side plates connected to both sides of a material plate are provided. A pocket-shaped cylinder that wraps the front and back of the floppy disk is formed by dividing it so that it will butt at the center of the material plate, and is divided into left and right sections. A binder-type notebook floppy holder has been proposed, which is provided with a locking projection so that a ring-shaped binding device equipped with a binder can be inserted into a binding hole formed near the upper edge of a material plate when a file is filed. . Further, in Japanese Utility Model Laid-Open No. 61-74584, a book-shaped box body covered with a hard package has a plurality of compartments for storing a frame-shaped floppy disk, and a floppy disk is stored in the compartment. While supporting the storage frame that it supports, the storage frame has a locking projection that fits into a recess provided on the inner peripheral surface of the storage section and a locking projection that fits into the recess of the floppy disk. A micro-floppy disk storage book-type box body has been proposed, which is configured to horizontally store a floppy disk in a storage frame body that is pivotally supported in each storage section.

[0003]

[Problems to be solved by the device]

 By the way, all of the above conventional ones store and hold a storage carrier such as a floppy disk or a compact disk, but the storage case proposed in Japanese Utility Model Laid-Open No. 176640/1985 has a large number of compact disks. While it is convenient to store compact discs indoors because it stores a number of them upright and side by side, the rack for storing compact discs is bulky and inconvenient when carrying compact discs, for example. Is. In this regard, the binder-type notebook floppy holder and the book-type box body for storing micro floppy disks are used to store floppy disks horizontally, so the holder and box body can be molded thin, which is convenient for carrying.

However, in these floppy holders and storage book type box bodies, the object to be stored is a floppy disk, and the storage portion for holding the floppy disk is formed in accordance with the size of the floppy disk. When a mini disc with a smaller diameter than that of the mini disc is stored, it is impossible to store the mini disc in a positioned state. In the binder type notebook floppy holder disclosed in Japanese Utility Model Laid-Open No. 5-44891, the side plate is folded back to hold the floppy disk with a pocket-shaped tubular body having upper and lower edges opened. If the recesses of the floppy disk and the locking projections become loosely fitted to each other due to mutual molding errors of the locking projections or aging, etc., the fittings between the recesses and the locking projections will be easily disengaged. There is a risk that the floppy disk will come out easily. In this regard, the micro floppy disk storage block type box body proposed in Japanese Utility Model Laid-Open No. 61-74584 fits on the locking projection of the storage frame body in which the floppy disk is pivotally supported in the storage section. Even if the recess and the locking projection are disengaged from each other, the floppy disk is surrounded by the frame-shaped storage section, so there is no risk of the floppy disk coming out of the storage section. The size of the book-shaped box that holds the disks is set so that multiple floppy disks can be stored, and the book-shaped box will be bulky for carrying a small number of floppy disks. Furthermore, since the storage area for a plurality of frame-shaped floppy disks is integrally formed on the inner surface of a book-shaped box covered with a hard package, it is bulky in weight, for example, one sheet. It is extremely irrational to carry a heavy and bulky book-shaped box to carry a floppy disk, but when carrying a floppy disk by itself, the storage frame that holds the floppy disk is pivotally attached to the storage section. It is uneconomical because it is necessary to prepare a separate case for the floppy disk because it cannot be removed.

The present invention is intended to solve such a problem, and can store and hold a small number of mini-discs or a large number of mini-discs. Moreover, when carrying a single mini-disc, a separate mini-disc is required. It is an object of the present invention to provide a binder type mini disk holder that does not require a case to be stored.

[0006]
