Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a compact disk case.
This prevents the disc, which records high-density information read by laser light, from getting dirty with oil from your hands when you put it in and take it out of the player, and also allows you to load a compact disc (CD) into the player while it is in the case. For example, it is expected that the usefulness of compact disks will be further enhanced by the ease of one-handed operation and ease of disk maintenance, and that they will become as popular as cassette tapes and video cassette tapes. Prevents dirt when not in use, and
A case that stores the compact disk so that it can be moved stably during use significantly increases the value of the compact disk.

[Conventional technology]

Utility Model Application Publication No. 56-9587 is a conventional example of loading DC into a player for each case. This includes an outer case used as a lid, magnets facing the case and the player, and upper and lower panels for pop-up inside the outer case.
The upper and lower frames used as cases containing CDs are
It has a structure that includes magnetic annular bodies that hold the CD between the upper and lower sides, and the upper and lower frames inserted between the opposing magnets of the upper and lower surfaces are deformed upward and downward by the attraction force of the annular magnetic body with the opposing magnets. To make the CD held between the upper and lower frames rotatable.

Forcing the deformation of the upper and lower frames to open up and down using magnets not only requires the above-mentioned complex mechanisms and parts for the player and case, but also requires rotation by floating the compact disc within the space created by the forced deformation. It is unreasonable to expect such stability. If the deformation does not occur as planned, the compact disk will be damaged or scratched. In particular, in order to make a compact disc that can be housed in a case for full-scale widespread use, it is necessary to reduce the cost and to have a case structure that guarantees safe and reliable internal rotation.

[Problem that the invention attempts to solve]

It protects the high-sensitivity information recording surface of a CD, especially from getting dirty with hand oils that are difficult to remove, and can be loaded with a CD into a CD player without incurring the materials and manufacturing costs of a CD storage case. In developing a CD case that can be operated with one hand, we also avoided moving parts or mechanisms that could cause trouble in order to make it trouble-free.

In line with the new development goal of protecting the CD recording surface even if it is not perfect as long as it is sufficient to achieve the purpose, we have created a compact disk storage case that is loaded in each case, which is essential for widespread use. This development is achieved with the simplest possible structure for the stability and reliability of the floating and rotating mechanism.

[Means for solving problems]

The present invention has a double insertion restriction member as a case structure, which is equipped with a control groove to restrict insertion on one of the upper and lower surface members and a control window on the other side, so that it can be used when loading, such as when operating with one hand while driving a car. The structure has a function to prevent incorrect insertion in the vertical and horizontal directions, which often occurs, and has at least three cushion holding members erected on the inner surface of the lower surface member at positions surrounding and sandwiching the compact disk. The rear edge of the upper surface member has a simple and safe floating guide function that prevents the disk from internally transversely displacing, and at the same time dislocates longitudinally and floats along the cushion holding member to enable rotation. It has a structure in which a label window wall is provided, and an inner wall is provided inside the rear edge of the lower member to provide a label holder, increasing the rigidity of the case to improve safety when carrying. A first engaging means is provided with an engaging opening in the wall and a claw member that engages with the engaging opening in a hinged manner at the leading edge of the upper surface member, and a second engaging member is provided at the rear of both side walls, and the lower surface member is provided with an engaging opening. These upper and lower surface members have a structure in which an engagement window is provided at a corresponding position to provide a second engagement means, and the upper and lower surface members are tightly attached by fitting between the claw member and the second engagement means. By configuring the first and second engaging means so that they can be opened and closed so that the CD inside can be cleaned when necessary, and at the same time do not narrow the internal space of the case, you can freely replace any CD you like with the case. do.

This invention has a case with a simple structure without any moving parts to avoid an increase in material and manufacturing costs, and a structure that allows the lid to be opened to clean the disk information recording surface that has become dirty due to long-term use or accidentally. Furthermore, it is a compact disc case that rotates inside the case so that CDs can be exchanged freely and can be inserted with one hand to prevent erroneous insertion.

[Function and Examples]

As shown in FIGS. 1 and 2, one embodiment of the present invention has a reading window 8 for operating an optical reading device on the lower surface member 2 of the case, and a disturbance window 7 for operating a turntable, and an upper surface member 3. It has an opening 32 for operating the clamper. In order to rotate and play the disc 1 within the case inserted into the compact disc player, the upper and lower surface members 3 and 2 of the case are provided with different functional parts as described above.

Therefore, a control groove 9 is formed in the lower surface member 1 and a control window 23 is formed in the upper surface member 3 as a regulating structure to prevent the device from being accidentally inserted upside down. Another control window 23 is formed in case the control groove 9 is unable to prevent improper insertion of the case. If the upper and lower drive windows 7 or the clamper opening 32 are not placed in the correct position, the internal CD
Take all possible precautions to protect internal disk 1 by avoiding contact with it.

The double restriction means for such protection includes a movable protrusion on the player side that engages with the control groove 9 and allows passage through the control groove 9, and a movable protrusion that engages with the control groove 9 to allow passage through the control groove 9. This is accomplished by a combination of means, such as providing the player with a carrier that engages with the carrier and moves the case inside.

The inclined portions 10 formed at the engagement start and end ends of the control groove 9 so as to be lower toward the tips make insertion of the case into the player smoother and more reliable one-handed insertion.

The front edge wall 11 erected from the lower surface member 2 is provided with the engagement opening, and the front edge of the upper surface member 3 is provided with a claw member 21 that fits into the engagement opening 12, and by these engagements, the upper and lower surface members 3, Tighten 2. When the engagement is released, the upper surface member 3 moves like a hinge to separate the claw member 21 without damaging it.

An inner wall 20 is provided near the rear edge of the lower surface member 2, and a label 33 is sandwiched between the inner wall 20 and a label window wall 30 erected on the rear edge of the upper surface member 3 (see FIG. 5). Both side walls are formed by abutting half-vertical walls 13, 28, 14, and 29 divided into upper and lower halves, and stand upright on the side edges of the upper and lower surface members 3 and 2, respectively, and the rigidity of the case is increased at these orthogonal portions. Both the front and rear parts of the half-standing walls 13, 14, 28, and 29 are provided with a rearward slope at the front and a forward slope at the rear so as to match the hinge-like movement of the claw member 21, and the upper surface member 3 is formed into a hinge. When the target is raised, the inclined and abutting surfaces 13 and 14 of both the front and rear parts are separated as they are.

Second engaging members 27, 27 are provided behind the side walls 28, 29 as second engaging means. In this embodiment, an outward claw member 25 is provided inside the upper member 3, and the side walls 13, 14 of the lower member 2 are provided at corresponding positions.
An engagement window 18 is opened. The pawl member 25 engages the window cutout side wall 16. A stepped portion 17 extending away from the side wall 16 is formed at the upper end of the second claw members 25 , 25 . 15 and 16 are internal walls for forming the engagement window 18.

This stepped portion 17 allows the second member 2 to close when closed.
5 is prevented from being accidentally pushed into the case. That is, when separating the upper surface member 3 in order to wipe dirt from long-term use or accidental dirt from the information recording surface of the disk 1, the second claw member 2
The engagement is released only when the two parts 5 and 5 are simultaneously deformed inwardly. That is, since this claw member 25 facing into the engagement window 18 does not protrude outside,
This prevents accidental opening and requires the use of a sharp object that fits into this hole when opening.

At least three cushion holding parts 4 are provided to prevent the disk 1 housed inside the case from moving laterally inside the case and to ensure proper engagement with the clamper or turntable. (see figure). This embodiment has a U-shaped member 6 facing each other at an undercut, and has a holding seat 6'' on the lower surface member 2.A cushion 6' attached to the holding seat 6'' and the U-shaped member 6 is placed inside these. The disk 1 is raised from the lower surface member 2 to prevent the disk 1 from being scratched. Furthermore, the U-shaped member 6
The height portion is a permissible space for further lifting the disk 1 from the cushion 6' when the turntable rotates the disk 1, and the disk 1 is guided by this height portion and floats vertically.

As a preferable means to add to the above configuration, an auxiliary wall is provided inside the label window wall 30 at the rear end of the upper surface member 3 so as to sandwich the inner wall 20 provided at the rear end of the lower surface member 2, and the inner wall 20 is provided as an auxiliary wall. A wall-clamping configuration is included. These auxiliary walls inner walls 2
0. The edge portion of the label window wall 30 is formed at an appropriate angle or inclination so that it can be opened or closed like a hinge.

After placing the disk 1 between the cushion holding parts 4, align the claw members 21 with the engagement openings 12, lower the upper member 3 like a hinge towards the lower member 2, and push it in, so that the second engaging member 27 can be attached to both upper and lower surfaces. Part 3,
Tighten 2. Half-standing walls on both sides 13, 14, 2
8 and 29 collide, and the label window wall 30 at the rear end collides with the inner wall 20 with the label 33 interposed therebetween, so that the case is integrated.

[Effect of idea]

In order to ensure that the case can be inserted into the player correctly, the double restriction means on the top and bottom members ensure that it will not be inserted incorrectly.It can also be inserted correctly with one hand even while driving a car, and the internal cushion retaining member ensures that the disc is inserted correctly. Not only does it float, but it also removes dirt from long-term use or accidental dirt from disk 1.
When it becomes necessary to wipe the dirt, or when you want to replace the disc with a preferred one, open the second engaging member 27 to open both upper and lower surface members 3, 2 in a hinged manner, remove the disc 1, and remove the dirt. This makes it a useful case for converting disks into cassettes, which is essential for the spread of compact disks.
