[0005]

[Problems to be solved by the device]

 However, according to this conventional case, since there are only two disc housing surfaces, the demand for increasing the number of discs to be housed can only be achieved by enlarging the vertical or lateral dimensions of both case bodies C1 and C2. I can't handle it.

However, in this case, since the plane size is significantly increased, it is bulky and very inconvenient to carry in a bag or the like or directly in a hand. For this reason, as a practical problem, as shown in the figure, there is a practical limit of accommodating four 3.5-inch floppy disks, two in each of the case bodies C1 and C2.

Therefore, the present invention is to provide a floppy disk case that increases the number of disks that can be accommodated and is compact and easy to carry.

[0008]

[Means for Solving the Problems]

 According to a first aspect of the present invention, the middle case body having the disk housing portions on both sides is sandwiched between the front case body and the back case body having the disk housing portion for housing the floppy disk on one side. Rarely, the front case body and the middle case body, and the middle case body and the back case body are connected to each other by hinges at one side thereof, respectively, so that they can be opened and closed.

According to a second aspect of the present invention, in the structure of the first aspect, one side of the floppy disk accommodated in the disk accommodating portion is provided in the disk accommodating portion of each of the front, middle, and back case bodies. A rotatable disc ejecting claw that pushes up to the outside is provided, and a recessed portion that is recessed toward the outer peripheral side is partially formed on the inner periphery of the side portion where the disc ejecting claw is provided in the peripheral portion of the disc storage portion. It is provided.

[0010]

[Action]

 According to the above configuration, both the front and back surfaces of the middle case body are added as the disk housing surfaces, so that the number of disks to be housed can be increased by two surfaces as compared with the conventional case.

Moreover, since the thickness of the middle case body is increased and the plane size is not changed, it is much more compact than the case of enlarging the vertical and horizontal sizes and is convenient for carrying.

Further, since it becomes possible to stand by itself due to an increase in the thickness dimension, it can be compactly stored in a stand-alone state.

On the other hand, in this case, the disc is often ejected with one hand in order to select the disc by manipulating the middle case body to turn the pages of the book.

In this case, according to the second aspect of the present invention, the disc take-out claw is pushed to push up the disc, and the moment the disc one side portion rides on the one side portion of the disc accommodating portion, the disc end surface is depressed by the concave portion. Since a gap is formed on the outside, you can put your fingertip in this gap and easily pick up the disc. Therefore, the disc can be easily taken out with one hand.

【Example】

 First Embodiment (see FIGS. 1 to 5) In this floppy disk case, a middle case body 13 is sandwiched between a front case body 11 and a back case body 12, and the front case body 11 and the middle case body 13 are inserted. The middle case body 13 and the back case body 12 are connected to each other by hinges 14 and 14 at their one sides so that they can be opened and closed.

Both the front and back case bodies 11 and 12 are formed by fitting an inner frame 16 into an outer frame 15 having a flattened shape.

On the other hand, the middle case body 13 is formed by fitting inner frames 18 and 18 on both front and back sides of an outer frame 17 in which the outer frames 15 of the front and back case bodies 11 and 12 are integrated back to back. A disc accommodating portion 19 for accommodating the disc D is formed in the inner frames 16 and 18 of each of the case bodies 11, 12, and 13.

Therefore, according to this floppy disk case, a total of four surfaces, one surface of both the front and back case bodies 11 and 12 and both surfaces of the middle case body 13, serve as the disk receiving surface, and the middle case body 13 is compared with the conventional case. Since the two surfaces are added as the disk accommodation surfaces, the number of disks accommodated can be increased by the two surfaces.

In the figure, in accordance with the conventional description, each of the case bodies 11, 12, 13 is formed in a rectangular shape, and each of the two disk storage portions 19 ... A case is illustrated in which a total of eight 0.5-inch floppy disks D (four in the conventional case) are accommodated.

Moreover, since the middle case body 13 is sandwiched between the front and back case bodies 11 and 12, only the thickness dimension of the case is increased by the middle case body 13 and the plane size does not change. For this reason, it is much more compact than when enlarging the vertical and horizontal sizes, and it is not bulky when carried in a bag or directly in your hand.

Further, since the thickness dimension increases, it becomes possible to stand by itself in the closed state, so that it can be compactly stored in the self-standing state.

By the way, in this case, since it is necessary to operate the middle case body 13 to turn the pages of the book and select the disks D ..., The disk D is often taken out with one hand. Therefore, the following configuration is adopted so that this one-handed disc ejection operation can be performed easily.

Each disc accommodating portion 19 has a depth dimension that is slightly larger than the thickness of the disc D, and prevents the disc D from moving during carrying and falling off in the time when the case is open. The disk D is formed with vertical and horizontal dimensions to be fitted in a tightly fitted state.

In order to make the storage condition of the disc D more stable, elastic pushing pieces 20 for pushing the disc D inward are provided at the two opposite sides of the disc storage portion 19 in the inner frames 16 and 18. In addition, the protrusions 21 that prevent the disc D from floating are provided on the sides of the hinges 14 and 14 side.

Further, a disc take-out pawl 22 for taking out the disc D 1 is rotatably attached to a side opposite to the hinge 14 side of each disc housing portion 19 ...

The disc take-out claw 22 has an operating portion 23 on the outside of the disc housing portion and a disc push-up portion 24 located inside the disc housing portion 19 on the opposite side of the rotation fulcrum, as shown in FIG. By pushing the operation portion 23, the disc pushing portion 24 pushes one side portion D1 of the disc D to the outside of the disc accommodating portion 19.

On the other hand, of the peripheral portions of the disk housing portion 19 of the inner frames 16 and 18 of the case bodies 11, 12, and 13, a side portion S provided with a disc take-out pawl 22 (hereinafter referred to as a pawl setting side portion). In the above, the rising walls 25 are formed so as to be slanted upward at both side portions sandwiching the disc ejecting claw 22, and at the remaining portions, the rising walls 26 are in close contact with the disc end face like other side portions. The disk D is formed perpendicular to the bottom surface of the disk housing so that the disk D can be housed in a stable manner. Reference numeral 27 is a horizontal wall that extends horizontally from the upper ends of these rising walls 25 and 26 to the outer peripheral side.

In this way, on the inner peripheral side of the claw installation side portion S, the concave portion 28 that is partially retracted to the outer peripheral side by the inclined rising wall 25 is formed.

As means for holding the front case 11 and the middle case body 13 and the middle case body 13 and the back case body 12 in the closed state, the stoppers 29, 29 are attached to the front and back case bodies 11, 12, respectively. 29, the middle case body 13 is provided with stopper holes 30, 30 through which the stoppers 29, 29 can be elastically engaged and disengaged.

In this structure, when one side D1 of the disc D is pushed up to the outside of the disc accommodating portion 19 by the disc ejecting pawl 22 as shown by the phantom line in FIG. 4, the fingers are released from the pawl 22. As shown in, the one side portion D1 of the disc is in a state of riding on the upper end portion of the vertical rising wall 26 at the side portion S on which the claw is installed.

In this state, a gap is partially formed on the outer circumference of the disc by the concave portion 28. Therefore, as shown by a phantom line in FIG. 5, a fingertip such as a forefinger is inserted into the gap portion and the disc is inserted. The one side portion D1 can be easily picked up.

Moreover, in this case, since the inclined rising wall 25 serves as a guide when the fingertip is also dragged to the lower side of the disc, the knob removing operation can be performed naturally and smoothly.

Therefore, the operation of pushing the disk ejecting claw 22 and then the operation of ejecting the disk D can be easily performed with one hand.

The operation portion 23 of the disc take-out pawl 22 is also formed with an inclined surface 23a that inclines upward in accordance with the inclined rising wall 25, so that the pawl 22 portion can also perform the disc knob take-out operation. Has become.

Second and Third Embodiments (Refer to FIGS. 6 and 7) Explaining only the differences from the first embodiment, both side portions of the disk ejecting claw 22 at the claw installation side S (in the first embodiment). In the second embodiment shown in FIG. 6, in the second embodiment shown in FIG. 6, the vertical rising wall 31 is recessed more outward than the rising walls 26 in other parts. In the third embodiment shown in FIG. 7, the recessed portion 28 is formed by notching the portion that straddles the rising wall 26 and the horizontal wall 27.

With the configurations of both the second and third embodiments, basically, the same operational effect as that of the first embodiment can be obtained.
