[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floppy disk case mainly used for carrying.

[0002]

2. Description of the Related Art Conventionally, in a portable floppy disk case, as shown in FIGS. 8 to 10, a pair of symmetrically formed case bodies C1 and C2 have a hinge 1 on one side thereof.
Both case bodies C are connected by
A floppy disk (hereinafter, simply referred to as a disk) D is housed in a disk housing portion 2 provided in each of C1 and C2.

In the figure, as the most general example, both case bodies C1 and C2 are formed in a rectangular shape.
1 illustrates an example of a floppy disk case in which 3.5-inch floppy disks are accommodated in the disk accommodating portions 2 provided for each of C1 and C2.

3 is an elastic pushing piece for pushing the disk inward,
Reference numeral 4 denotes a protrusion that prevents the disc from rising, and 5 denotes one side of the disc when the disc is taken out.
A disk ejecting claw for pushing it up to the outside.

[0005]

However, according to this conventional case, since there are only two disk housing surfaces, there is a demand for increasing the number of disks that can be housed in the case body C1 or C2 vertically or horizontally. It can only be dealt with by increasing the dimensions.

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

Therefore, the present invention provides a floppy disk case in which the number of disks to be accommodated is increased, the disk is compact and convenient to carry, and the disk can be easily taken out.

[0008]

DISCLOSURE OF THE INVENTION The present invention provides a middle case in which a disk containing portion is provided on both sides between a front case body having a disk containing portion for containing a floppy disk provided on one side and a back case body. While the body is sandwiched, the front case body and the middle case body, and the middle case body and the back case body are connected by hinges at one side of each other to be openable and closable, while the front, middle and back cases A rotatable disk ejecting claw that pushes up one side of the floppy disk accommodated in the disk accommodating part to the outside of the disk accommodating part is provided in the disk accommodating part of the body, and the above-mentioned part of the peripheral part of the disk accommodating part is A recessed portion that is recessed toward the outer peripheral side is partially provided on the inner circumference of the side where the disk take-out claw is provided.

[0009]

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

Further, 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 to carry.

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 because the disc is selected by operating the middle case body to turn the pages of the book.

In this case, the disc take-out claw is pushed to push up the disc, and the moment when the disc one side portion rides on the one side portion of the disc accommodating portion, the concave portion forms a gap on the outer side of the disc end surface. You can put your fingertips in the gap and easily pick up the disc. Therefore, the disc can be easily taken out with one hand.

[0014]

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 to form a front case body 11. The middle case body 13, the middle case body 13 and the back case body 12 are connected to each other by hinges 14 and 14 at one side portion thereof so as to be openable and closable.

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 having a shape in which the outer frames 15 of the front and back case bodies 11 and 12 are integrated back to back. Inner frame 1 of each case body 11, 12, 13
6 and 18, a disk housing portion 19 for housing the disk D
Are formed.

Therefore, according to this floppy disk case, a total of four surfaces, that is, 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 drawing, each case body 1 is adapted to the conventional description.
1, 12 and 13 are formed in a rectangular shape, and two 3.5-inch floppy disks D are provided in two disk storage portions 19 ... Each of which is provided by vertically dividing the inner frames 16 and 18 into two pieces (conventional). The case exemplifies a case in which a total of four sheets 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 in the case of enlarging the size in the vertical and horizontal directions, and is not bulky when carrying it in a bag or directly in a 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 the disc ejecting operation with one hand can be easily performed.

Each disc accommodating portion 19 has a depth dimension slightly larger than the thickness of the disc D, and
The disk D is formed with vertical and horizontal dimensions so that the disk D is fitted in a close-fitting state so that the disk D does not move during carrying and the case does not fall off in an open beat.

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 receiving portion 19 in the inner frames 16 and 18. And hinges 14 and 1
A protrusion 2 that prevents the disc D from being lifted up on the 4th side.
1 is provided.

Further, the hinge 1 of each disc accommodating portion 19 ...
A disc take-out claw 22 for taking out the disc D is attached to the side opposite to the 4 side so as to be rotatable around a horizontal shaft (not shown).

The disc take-out claw 22 has an operating portion 23 on the outside of the disc accommodating portion and a disc pushing portion 24 located in the disc accommodating portion 19 on the opposite side, as shown in FIG. By pressing the operation unit 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 in the inner frames 16 and 18 of the case bodies 11, 12, and 13, a side portion S (hereinafter, referred to as a side portion) provided with a disc take-out pawl 22 is provided.
(Referred to as the claw setting side portion), the disk ejecting claw 22
The rising wall 25 is formed so as to be inclined outwardly on both sides of the rising edge, and in the remaining part, the rising wall 26 is in close contact with the disk end surface like the other sides, and the disk D can be stably accommodated. Thus, it is formed perpendicularly to the bottom surface of the disc housing portion. 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.

Thus, on the inner peripheral side of the claw installation side S, a concave portion 28 is formed which is partially retracted to the outer peripheral side by the inclined rising wall 25.

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 front and back case bodies 11 and 12 have stoppers 29 and 29, respectively. This stopper 29 on the case body 13,
Stop holes 30, 30 through which 29 can be elastically disengaged are provided.

In this structure, one side D of the disk D is moved by the disk take-out claw 22 as shown by the phantom line in FIG.
1 is pushed out of the disc accommodating portion 19 and then the finger is released from the claw 22, as shown in FIG.
1 is in a state of riding on the upper end portion of the vertical rising wall 26 at the claw installation side portion S.

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

Moreover, in this case, the inclined rising wall 25
Since it serves as a guide when the fingertips are pulled into the lower side of the disc, this knob removal operation can be performed naturally and smoothly.

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

The operation portion 23 of the disc ejecting claw 22
Also, an inclined surface 23a is formed so as to incline upward in accordance with the inclined rising wall 25, and the claw 22 portion can also perform the above-mentioned disc knob removing operation.

Second and Third Embodiments (Refer to FIGS. 6 and 7) Only the differences from the first embodiment will be explained.
6 on both sides of the disk take-out pawl 22 (the portion where the inclined rising wall 25 is provided in the first embodiment).
In the second embodiment shown in FIG. 7, the vertical rising wall 31 is provided so as to be recessed to the outer peripheral side with respect to the rising walls 26 of the other parts, and in the third embodiment shown in FIG.
The recessed portion 28 is formed by notching the portion that straddles 6 and the horizontal wall 27.

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

[0036]

[Advantage of the Invention] As described above, according to the present invention, the table,
Since the four disk housing surfaces are formed by the three inner and inner case bodies, the number of disks housed can be increased by two surfaces as compared with the conventional case.

Further, 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, which is convenient for carrying.

Further, the increase in the thickness makes it possible to stand by itself in the closed state, so that it can be compactly stored in the self-standing state.

On the other hand, when the disc is taken out, a gap is formed on the outer side of the disc end face by the concave portion when one side of the disc rides on the one side of the disc accommodating portion by the operation of the disc take-out claw. You can easily pick up the disc by putting your fingertip on it.
Therefore, the disc can be easily taken out with one hand.
