Next, the CD cassette case 42 having the above structure
The operation of 0 will be described.

The operation of taking out the CD from the CD cassette case 420 accommodating the CD will be described.

As shown in FIG. 21, in the CD cassette case 420 accommodating the CD, the inner lid 423 is
Covers the surface of the case main body 421, and the surface of the inner cover 423 is covered by the outer cover 451. In the recess 428, the flattened raised piece 42 is placed on the moving piece 424.
6 and the CD mounting piece 425 are overlapped. By placing the CD on the raised piece 426 and the CD mounting piece 425, the CD is housed in the recessed portion 428. Therefore, in this CD cassette case 420,
It can be said that the CD is stored and held in a compact state. A part of the surface of the CD housed in the recess 428 is pressed by the pressing piece 452, and the other surface of the CD is pressed by the pressing plate 463. A mounting protrusion 462 is fitted in the mounting hole of the CD. Therefore, the accommodated CD is stably retained and accommodated in the concave portion 428, and does not rattle.

First, the outer lid body 451 covering the surface of the inner lid body 423 is opened by rotating it via the second coupling portion 450.

Then, the inner lid 423 is attached to the first connecting portion 422.

It moves toward the connecting portion 422 side. At this time,
Since the moving piece 424 is inserted into the lower communication hole 431, when the moving piece 424 moves, the moving piece 424 floats and causes abnormal movement, the moving piece 424 is twisted, or the moving piece 424 is caught. No abnormalities will occur. In other words, by forming the width of the moving piece 424 in the lateral direction to be slightly smaller than the width W _{1 of the} communication hole 431, the communication hole 431 is moved by the moving piece 42.
The function of guiding the movement of 4 is exhibited.

Further, since the moving piece 424 is provided with the opening window 470, the fixing piece 461 of the CD mounting piece 425 is fixed to the bottom surface of the concave portion 428 in the area of the opening window 470. Therefore, the moving piece 424 can be smoothly moved or reciprocated without being blocked by the fixed piece 461.

By moving the moving piece 424, the moving piece 424
The protruding piece 426 connecting one end to the other end of the
4 receives a pressing force toward the first coupling portion 422 side, and the end of the CD mounting piece 425 rotatably coupled to the end of the raised piece 426 is rotatably coupled to C.
Since the fixing piece 461 of the D mounting piece 425 is fixed, the CD mounting piece 425 and the protruding piece 426 are bent in a mountain shape at the portions where they are connected to each other, and thus the CD mounting piece 425 and the protruding piece 426 are raised in a mountain shape as a whole. The upper surface of the CD mounting piece 425 that is raised in a chevron shape faces the inner lid 423 side, and the upper surface of the raised piece 426 faces the side opposite to the inner lid 423.

The movement of the moving piece 424 causes the inner lid 423 to move.
The pressing piece 452 that connects one end to the back surface of the
The inside of 53 is moved to the side of the inner lid 423, and the tip of the pressing piece 452 is retracted. As a result, the pressing piece 452 is
From the state where a part of the surface of the CD was covered until then, C
The surface of D changes to a state in which it is not covered.

In other words, the pressing piece 452 is arranged on the CD placing piece 425 while retracting into the upper communication hole 453 while the CD placing piece 425 is raised.
Since a part of D is held down, the CD is stably held without falling off from the CD mounting piece 425 when the CD mounting piece 425 is rising.

Since the CD mounting hole is fitted into the mounting protrusion 462 provided on the CD mounting piece 425,
Also by this, when the CD placing piece 425 is rising, the CD is stably held without falling off from the CD placing piece 425.

As shown in FIG. 25, when the inner lid 423 is completely opened and the case body 421 and the inner lid 423 are placed on the same plane, the CD mounting piece 425 is placed.
The raised piece 426 and the raised piece 426 are raised in a mountain shape. At this time, the CD mounting piece 425 is stably supported by the raised piece 426. In this state, since the CD projects obliquely from the case body 421, the CD can be easily taken out from the CD mounting piece 425.

When storing a CD in the CD cassette case 420, the reverse operation of the operation for taking out the CD stored in the CD cassette case 420 is performed.

As described above, the present invention CD cassette case 420
Although one embodiment has been described, the present invention is not limited to the above embodiment.

When a CD is stored in the CD cassette case 420, the reverse operation to the above is carried out.

That is, the CD is placed on the inclined surface of the CD mounting piece 425 which is raised in a mountain shape by the raised piece 426. In this case, the CD is arranged so that the mounting protrusion 462 is fitted into the mounting hole of the CD. Since the pressing piece 452 is retracted into the upper communication hole 453 and the tip of the pressing piece 452 is barely exposed in the recessed portion 428, the CD can be arranged on the upper surface of the CD mounting piece 425 without any trouble.

Next, the inner lid 423, which is on the same plane as the case body 421, is rotated so as to cover the surface of the case body 421. By the rotation of the inner lid body 423, the moving piece 424 is pushed and moves toward the side opposite to the first coupling portion 422, and the movable piece 424 also moves the movable tip 426 by the first coupling. It moves toward the side opposite to the portion 422. The movement of the tip of the raised piece 426 causes the CD mounting piece 425 to rotate from its obliquely arranged state to a horizontal position. When the CD mounting piece 425 is horizontal, the CD is mainly placed in the recess 428.

As the CD mounting piece 425 shifts from the oblique arrangement to the horizontal arrangement, and as the inner lid 423 covers the surface of the case body 421, the pressing piece 452 moves the CD on the CD placing piece 425. Push out to cover a part of the surface.

When the CD mounting piece 425 is placed horizontally in the recessed portion 428, a piece 45 of the surface of the CD is pressed.
2 covers and presses down, so the CD has this recess 42
It does not fall off from 8, and is stably held.

After the CD is accommodated in the recess 428, the outer lid 451 is rotated to cover the surface of the inner lid 423.

In the invention including Example 4, the mechanical relationship between the moving piece and the inner lid is similar to the mechanical relationship between the moving piece and the inner lid in the invention including Example 1 described above.

Although the moving piece in this Example 4 is provided with an opening window, in the invention including this embodiment,
The opening is not always necessary, and the reciprocating motion of the moving piece is CD.
The opening is not always necessary as long as the mechanism or means that is not hindered by the presence of the mounting piece or the positional relationship between the moving piece and the CD mounting piece is taken into consideration.

In the invention including the fourth example, the protruding piece has a function of allowing the CD mounting piece to be obliquely raised by the reciprocating movement of the moving piece or to be positioned horizontally, in other words, the moving piece. There is no particular limitation on the shape and structure as long as it has a function of being able to be raised in a mountain shape and positioned horizontally with the CD mounting piece by reciprocating motion. Further, the number of raised pieces is not limited to one, and may be a plurality.

(Example 5) The CD cassette case 501 of the present invention, which is an example of the CD cassette case shown in FIG.

And a lid 5 that covers the case body 502.
When the case body 502 is opened by rotating 03, the lid 5
The short piece 505b is connected to the connecting portion 504 in accordance with the rotation of 03.
When the lid body 503 is rotated so as to cover the front surface side of the case body 502, the short piece 505b is pushed from the coupling portion 504 side and moves. The chevron ridge 506 is joined to the short piece 505b with one end as a fixed end, and the other end with the other end as a turning end.
Is fixed to the bottom surface of the joint between the pair of longitudinal pieces 505a in the vicinity of the coupling portion 504 so as not to be displaced.
It is characterized in that it has a mountain fold line 506a capable of mountain fold in the central portion and is formed in a plate shape.

In this CD cassette case 501, either the inclined surface facing the short piece 505b side or the inclined surface facing the connecting portion 504 of the chevron-shaped raised piece 506 is used as a CD mounting piece, It may also be a raised piece. For convenience of explanation, the mountain fold line 506a of the mountain-shaped protruding piece 506 is formed at a position of about 2/3 of the entire length of the mountain-shaped protruding piece 506 from the fixed end side, and the mountain fold line 5 is formed from the fixed end.

[0279] The CD mounting piece 50 in the Yamagata protrusion piece 506.
In 6b, to ensure the loading of the CD,
It is preferable that the accommodating portion capable of accommodating the is provided with, for example, a pocket.

The structure of the connecting portion 504 is not limited as long as it has the above-mentioned function. For example, as shown in FIG. 26, the surface on the end side of the case body 502 and the back surface of the lid body 503, that is, the case body 502 are connected to each other. A connecting portion 504 made of a flexible and strong sheet that joins the surface overlapping the surface of the case main body 502 when covered, and is not damaged by a large number of bending operations. From the mounting holes formed on both side surfaces of the main body 502, the pins rotatably fitted into the holes, and the pair of mounting pieces extending from both side surfaces of the lid body 503 and erected the pins. And the other known coupling means.

The thus constructed CD cassette case has the following functions.

When storing a CD in this CD cassette case, first, as an initial state, the cover body 503 covers the front surface side of the case body 502, and the recess 502a covers the cover body 503.
It is supposed to be closed. The lid body 503 is the case body 50.
In the state in which the lid 2 is covered, the chevron-shaped protruding piece 506 is flat and is accommodated in the recessed portion 502a.

The lid 50 is so exposed as to expose the concave portion 502a.

The raised piece can support the digital recording medium mounting piece, or can smoothly raise the digital recording medium mounting piece.

(11) Since the length of the digital recording medium mounting piece from the rotating end to the tip is designed to be longer than that of the digital recording medium, the digital recording medium can be stably mounted on the digital recording medium mounting piece. Can be housed and arranged.

(12) Since the pressing piece is provided at the tip of the raised piece on the side of the digital recording medium placing piece, the digital recording medium placing piece on which the digital recording medium is placed rises from a flat state or vice versa. It is possible to prevent the digital recording medium from dropping or shifting from the digital recording medium mounting piece by the pressing piece when the raised state changes to the flat state. Therefore, it is possible to store the digital recording medium in the case body or take out the digital recording medium from the case body without any trouble.

(13) The digital recording medium mounting piece is formed such that the length from the rotating end to the tip is shorter than the length of the digital recording medium and longer than 1/2 of the length of the digital recording medium. Therefore, the mounting state of the digital recording medium on the digital recording medium mounting piece does not become unstable, and when the mountain-shaped protruding piece is raised in a mountain shape, the digital recording mounted on the digital recording medium mounting piece is performed. Since the medium is in a state of projecting and extending further than the apex of the mountain-shaped protruding piece, it becomes easy to take out the digital recording medium from the digital recording medium mounting piece, and on the diagonally raised digital recording medium mounting piece. It becomes easy to mount and store the digital recording medium on the disk.

(14) Since the rotation end of the digital recording medium mounting is connected to the moving end of the movable body or its vicinity and the other end of the digital recording medium mounting piece is connected to the raised piece, the chevron shape is formed. When the raised piece is raised in the shape of a mountain, the digital recording medium placement piece can be raised obliquely by the raised piece that is rotated by the movement of the moving body, or the raised digital recording medium can be lowered.

(15) Since the fixed end of the raised piece is connected to the bottom surface of the case body through the opening provided in the movable body, the movement of the movable body is hindered despite the fixing by the fixed end of the raised piece. Can be done without. Moreover, the digital recording medium mounting piece can be raised obliquely so as to face the side opposite to the coupling end.

(16) One end of the digital recording medium mounting piece is connected to the raised piece, and the other end of the digital recording medium mounting piece is connected to the bottom surface of the case body. The digital recording medium mounting piece can be raised diagonally by raising the piece diagonally, and the digital recording medium placing diagonally raised by lowering the raised piece which is raised diagonally by the movement of the moving body The piece can be lowered flat.

(17) Since the other end of the digital recording medium mounting piece is immovably coupled to the bottom surface of the case body through the opening provided in the moving piece, Despite its existence, the moving body can be moved smoothly.

(18) Since the digital recording medium mounting piece is provided with the accommodating portion, the digital recording medium can be easily and surely accommodated on the digital recording medium mounting piece. In particular, when the mountain-shaped protruding piece is raised or changes from a raised state to a flat state, the digital recording medium on the digital recording medium placing piece is prevented from being displaced or falling off.

(19) When the accommodation portion of the digital recording medium placing piece is a pocket, the digital recording medium can be safely and reliably accommodated on the digital recording medium placing piece.
