DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description is for a floppy disk.
However, the fact that the present invention can be applied to any disc
It is clear from the fact that the composition of the plan does not depend on the nature of the disk
Would be . Floppy disk case 10 of the present invention
As shown in FIG. 1A, a case main body 20 having an opening 21 for taking in and out the floppy disk 11 and a floppy disk 11 fixed and inserted into the inner side surface 22 of the case main body 20 are held. Floppy holding member 30. FIG. 1 (b) is the same as FIG.
FIG. 3 is a view as seen from the direction of arrow A. As described later, when the L-shaped member 31 inside the case 10 is stopped,
And a state in which the floppy disk 11 is stored and held as shown in FIG.

The case body 20 has substantially the same shape and size as the closed state of the conventional 3.5-inch type floppy disk case, but has an opening 21 for smoothly inserting and removing the floppy disk 11. Moreover, there is a slight width corresponding to the arrangement of the floppy holding member 30. Further referring to FIG. 1A, recesses 24 are provided in the upper and lower portions of the case main body 20. This is necessary in order to push the back of the floppy disk 11 when removing the stored floppy disk 11 and to remove the disk. It is preferable that the depression 24 is located in the middle of the opening 21.

FIG. 3 is an enlarged view of the floppy holding member 30 of FIG. The floppy holding member 30 is mainly
(See FIG. 4 (b).) A fixing portion 39 having a protrusion 38 having a groove 36 having a saw-like unevenness, and a hole 3 of the fixing portion 39.
7, a coil spring 40 fitted to the front of the moving bar 32, an L-shaped member 31 having a support plate 42 and a hemispherical projection 43, and both ends in opposite directions. And a leaf spring 34 having one end 33 fixed to the moving rod 32 and the other end 35 inserted into the groove 36 of the fixing portion 39.

FIG. 4A is a view of only the fixing portion 39 of FIG. The fixing portion 39 is formed integrally with a protrusion 38 having a hole 37 and a groove 36. FIG. 4 (b)
FIG. 5 is a cross-sectional view of the protrusion 38 of FIG. The size of the hole 37 of the projection 38 is such that the moving rod 32 causes various movements depending on the horizontal direction (in FIG. 4A), the vertical direction, and the direction perpendicular to the paper surface by the groove 36.
Regardless of this, it is a size that can move smoothly. The end projection 41 is the same as the projection 38 without the hole 37.

FIG. 4A shows the shape of the groove 36 in a plan view. The groove 36 has a more characteristic structure. FIG. 5 is a diagram in which the vertical cross section of the heart-shaped groove 36 is linearly stretched. From FIG. 5, the groove 36
You can see that the bottom of the is serrated,
The movement of the other end 35 of the leaf spring 34 inserted into the groove 36 is restricted to one direction (that is, only the counterclockwise movement is possible in the heart-shaped groove 36 in FIG. The movement from point d to point c, from point c to point b, and from point b to point a is prevented by the step.) As a matter of course, the inclination of the groove 36 allows the leaf spring 34 to easily move by the force of the coil spring 40 and the force of the finger.

Although the moving rod 32 moves in various directions as described above, the moving rod 32 is largely
7 (in FIG. 3, only in the vertical direction)
Limited. However, the movement in the up and down direction is also caused by the movement rod 32.
The other end 35 of the leaf spring 34 fixed to is restricted by moving the groove 36 as described above. An L-shaped member 31 for receiving and holding the floppy disk 11 near the front portion is fixed to the moving rod 32 so that the coil spring 40 can be accommodated therein. The L-shaped member 31 has a support plate 42 for receiving the tip of the floppy disk 11 and a hemispherical projection 43 fitted to the concave portion 12 of the floppy disk 11 to hold the floppy disk 11. Further, the moving rod 32 has its distal end inserted into the coil spring 40. As shown in FIG. 1, the coil spring 40 is disposed between the inner side surface 23 of the case body 20 and the vicinity of the fixing point of the L-shaped member 31, and the opening corresponding to the position of the moving rod 32 is formed with respect to the moving rod 32. A force in the direction of the part 21 is applied.

Next, the operation will be described. Push the back of the floppy disk 11 and place the floppy disk 11 in case 1.
0, the hemispherical projection 43 of the L-shaped member 31 first contacts the right end of the tip of the floppy disk 11,
Then, along the side surface of the floppy disk 11,
At this time, since the L-shaped member 31 has elasticity, a force is applied outward by the hemispherical projection 43 to bend. This bending continues until the concave portion 12 and the projection 43 are fitted. When fitted, the floppy disk 11 is held without falling off the case 10. This fitting is performed by moving the other end 35 of the leaf spring 34 to which the moving rod 32 is coupled from the point a of the groove 36 (when the point a is at the first stop state of the L-shaped member 31) to the point b. Happens on the way.
Simultaneously with the fitting, the tip of the floppy disk 11 comes into contact with the support plate 42 of the L-shaped member 31, and the moving rod 32 is moved. In response, the other end 35 of the leaf spring 34 fixed to the moving rod 32 also moves along the groove 36. As described above, the movement of the other end 35 along the groove 36 is caused by the movement of the moving rod 32.
Of the L-shaped member 31 is restricted.

After that, when the other end 35 reaches the point b, the step falls and the coil spring 40 moves from the point b to the point c to drop the step and stop.
Is the second stop state). To remove the floppy disk 11,
1 is pushed from the depression 24. Then, the other end 35 moves the inclination from the point c to the point d, falls down the step, and then the spring 40
Is moved to the point a by the force of and falls down the step to stop. At this stop, the floppy disk 1
Take out the back of 1 with your fingers. Therefore, the human push operation is performed while the leaf spring 3 is pressed against the force of the coil spring 40.
The other end 35 of 4 moves the groove 36 from point a to point b to point d from point c.
The movement from point b to point c and from point d to point a is performed by the coil spring 40. In this manner, the other end 35 of the leaf spring 34 moves along the groove 36 having the saw-like unevenness, so that the floppy disk 11 is inserted into the case 10 and stored and held or taken out by simply repeating the push operation. It becomes possible.

As a matter of course, the distance w between the point c and the point b or the point d is determined by the distance between the support plate 42 of the L-shaped member 31 and the case body 20 so that the support plate 42 does not contact the inner side surface 23. The coiled spring 40 is shorter than the distance from the side surface 23 and the other end 35 can reach the point b or the point d.
Is in a state where it can be further contracted.

On both sides of the floppy disk 11,
Since the concave portion 12 as shown in FIG. 2 exists, if the insertion from the head of the floppy disk 11 is not erroneous, it is possible to store and hold the floppy disk 11 regardless of whether it is inserted from the front or the back.

[0015]

With the above arrangement, according to the invention], it has become possible to provide a case for disc capable out the disc only by repeating the push operation without the need of opening and closing of the case. This provides a new format for a disk case .

While the preferred embodiment of the invention has been illustrated and described, what is presently considered, those skilled in the art will appreciate that
It will be apparent that various changes and modifications can be made without departing from the spirit of the invention. All such changes and modifications are to be included in the technical concept of the present invention.
