【Example】

(Embodiment 1) This will be described in detail with reference to FIGS. 1, 2, 3, 4, and 5.

FIG. 1 is an external perspective view of a case 1d of a disk cartridge 1 containing a disk 2 (CD) known as a reproduction-only disk when a shutter 3 is opened, and FIG. 2 is a perspective view of the disk cartridge 1 after use. 3 is a perspective view showing the state in which the shutter 3 is closed, FIG. 3 is an assembled sectional view when FIG. 4 is cut along a horizontal line, FIG. 4 is a plan view of FIGS. 1 and 2, and FIG. 4 is an assembled sectional view when section 4 is cut along a vertical line.

In the figure, 1d is a resin case containing a first disk 2 (CD) used exclusively for reproduction, and although not shown, it is generally a front case and a back case. It is configured. Then, the disk 2 is housed in the hollow portion formed of them. Reference numeral 3 denotes a shutter that opens and closes the opening 1a and the like of the case 1d, and has grooves 3a and 3a as guide means for the case 1d on the side surface, and the grooves 3a and 3a engage with the rail portion of the case 1d. It fits. Further, the shutter 3 is provided with a case 4 accommodating a 3.5-inch FD (floppy disk) 5 known as a second disk inside the shutter 3 in such a manner as to be sandwiched in a recess as shown in FIGS. 3 and 5. When the opening 1a of the shutter 3 is opened and closed, the case 4 of the FD also moves in the same direction. The case 4 is provided with an opening 4a for a magnetic head for accessing the disk 5, and the opening 4a is normally closed by a shutter (not shown) provided in the case 4 as is well known. However, by engaging the shutter with a part of the case 1d, the shutter 3 is opened and closed in synchronization with the opening operation of the shutter 3 with respect to the case 1d. Therefore, when the shutter 3 shown in FIGS. 1 and 4 is opened with respect to the case 1d, another shutter arranged in the case 4 also opens the opening 4a of the case 4. And the shutter 3
By the movement of, the opening 4a of the case 4 is positioned outside the outer shape of the case 1d. Also, due to the movement,
As shown in FIG. 1, an opening 1a is formed on the front side of the case 1d, and the center hole 2 of the first disk 2 is formed from the opening 1a.
a is exposed. As shown in FIG. 4, also on the back surface of the case 1d, an opening (vertically long) that is developed in the vertical direction of FIG. 4 is formed by the movement of the shutter 3. Thus, the first disk 2 housed in the case 1d is
It is exposed through the respective openings of the case 1d from the back side and is clamped from above and below onto a turntable on a well-known spindle motor such as a CD player and a drive so that it can be rotated. Also, through the vertically elongated openings on the back side. A well-known optical head can be accessed.

On the other hand, the case 4 of the second disk is housed inside the shutter 3. The shutter 3 has a portion facing the opening 4a and a second disk 5 in the case 4. Since the notch is provided in the portion facing the clamp means 5b, when the shutter 3 moves to the position shown in FIG. 1 or the position shown by the imaginary line in FIG. 4, the second disk 5 is accommodated by the movement. The other shutter provided in the case 4 is also opened as described above, so that the second disk 5 is also exposed through the opening 4a and the notch of the shutter 3, and the disk 5 and The disk clamping means 5b is also ready to be attached to the applicable FDD (floppy disk drive) of the case 4. Simultaneously with mounting, the clamp means 5b of the disk 5 is clamped to the turntable (not shown) through the notch, and the notch and the opening 4
Since the disk 5 is completely exposed from a (present on the front and back), a magnetic head (not shown) or the like can be accessed, and the disk 5 can be read and written.

According to the present invention, when the disk cartridge 1 is not in use, that is, when the disk cartridge 1 is not mounted on the player or drive, FIG.
As shown in FIG. 3, the appearance is almost the same as that of a normal disk cartridge containing a single disk, but when the disk cartridge 1 is inserted into the player or a drive, the shutter 3 and the player are inserted. Alternatively, the shutter is opened / closed to the state shown in FIG. 1 by the action of the shutter opening / closing means (not shown) of the drive. In this state, the disk cartridge 1 is brought into a well-known approaching operation to the spindle motor side, and the respective disks 2 and 5 are clamped by the spindle motors of the respective players or drives.
d and case 4 must be accurately positioned in their respective players or drives. But,
This positioning may be disturbed by variations in each part of the player or the drive, variations in each part of the cases 1d, 4 and the like. In the present invention, even if these variations occur in each part, the function is prevented from being impaired.
That is, when the cases 1d and 4 are in the state of FIG.
The play between the rail portion of the case 1d and the guide grooves 3a, 3a of the shutter 3 is set to be considerably small. However, when the disk cartridge 1 is inserted into the player, drive, etc. for the mounting and the shutter 3 is moved to the position shown in FIG. 1 by the opening operation, the play of the rail portion and the guide grooves 3a, 3a moves up and down ( It is configured to increase in both the thickness direction of the case) and the left and right (direction orthogonal to the operation direction of the shutter 3). Therefore, with respect to the case 1d, the shutter 3 and the case 4 are vertically
It becomes possible to move left and right relatively. The opening / closing direction of the shutter 3 can be adjusted by increasing / decreasing the opening / closing stroke. Therefore, at the time of the mounting, the case 1d is positioned at the optimum position with respect to the player of the disk 2 by the action of the guide hole 1c of the case 1d provided in the case 1d, and the case 4 is the case 4. By the action of the guide hole 4c of the case provided on the disk, the disk 5 is positioned at the optimum position with respect to the drive. At the time of the positioning, even if the positioning elements of the respective cases have some deviations due to the variations of the respective parts, the deviations absorb each other, and as described above,
Each case is uniquely positioned in the optimum position.
After that, the first and second discs 2 and 5 in the case are clamped by the spindle motors of the players and drives, respectively, so that proper gaps are secured between the discs and the cartridges, respectively. The disk can be rotated without interference, and read or write operation can be performed according to a command from the player or drive. These can operate either on their own or in cooperation with each other.

(Embodiment 2) Although the embodiment 1 describes the type in which the disk 4 and the case 4 accommodating the second disk 5 are provided in the disk cartridge 1, the invention is not limited to this, and It is applicable as follows.

The inner surface of the shutter 3 shown in FIG. 4 is formed in a box shape, and the second disk 5 from which the case 4 is removed is installed inside the box shape with some play. During the opening operation, the disk 5 is moved along with the movement of the shutter 3, so that the head such as the FDD and the spindle motor do not interfere with the case 1d or the head and the spindle motor for the first disk. Since it can be arranged as described above, the same operation as that of the first embodiment can be performed at this position.

(Embodiment 3) The width (shown in FIG. 5) of the shutter 3 shown in FIG.
The case 1d is expanded to the full width of d, and the case 1d
When the shutter 3 of FIG. 4 is intentionally opened beyond the position shown by the imaginary line in FIG.
It is also possible to remove it from d. When the shutter 3 is removed from the case 1d together with the case 4, the case 1 is removed.
A lateral hole is formed on the side surface of d. If the first disk 2 is slid out from the lateral hole, a disk on which other information is written is loaded, and the shutter 3 provided with the case 4 is attached again and used again. A personal computer, a game machine, etc. can be operated as a combination of information different from the above combination. Also, the disk 2 can be replaced by moving the shutter 3 by an appropriate amount without removing it from the case 1d. Further, the disk to be replaced is not limited to the first disk, but may be the second disk.

[0019]

As described above, according to the present invention, for example, a read-only CD (compact disc) 2 and a readable / writable second disc 5 are accommodated in the disc cartridge 1 at the same time, It is configured so that it can be handled as one package from the user's point of view. Therefore, by mounting the disk cartridge 1 on a dedicated drive described later capable of handling a plurality of disks, information is read from the first disk 2, and a personal computer,
The CPU of the game machine or the like performs arithmetic processing, and if necessary, the processing result or the like is written to the second disk 5, and if necessary, the data is combined with data input from another input means such as the personal computer or the game machine. , The personal computer, the game machine, etc. can be operated again depending on the relationship with the information of the first disk 2.

A disk cartridge having such a function has already existed as a type using a semiconductor RAM or ROM. However, semiconductor RAM, RO
Although M is still expensive at the present time and it is difficult to implement it unless it has a relatively small recording capacity, the disk system of the present invention has a ROM / RAM ratio of cost to capacity of the conventional semiconductor system. It will be overwhelmingly cheaper than. In the case of the disk system, how to compactly accommodate a plurality of disks while ensuring reliability in one package was a problem, but according to the structure described in the embodiment of the present invention, the disk cartridge is used. Not only the structure, but also the structure of the player or the drive and the cost can be easily implemented without making the structure complicated. A player or drive using the disk cartridge may have a known CD player structure for the disk 2, and a known floppy drive structure for the disk 5. The spindle motors of the two means are installed so as to be displaced from each other by an amount of deviation between the center positions of the disk 2 and the disk 5 shown in FIG. 4, and the spindles are considered in consideration of the height of the two disks when clamped. The height of the motor turntable should be determined and placed.

In one embodiment of the present invention, the centers of the first disk 2 and the second disk 5 are different from each other. This is because the outer shapes of the two types of players or drives allow for compact arrangement without interference with each other, and the movement amount of the shutter 3 for the opening operation is minimized. It is because of consideration. In addition, the protrusions 1b, 1b,
1b and 1b are arranged around the disk 2,
This is because when the disk cartridge 1 is not attached to the player or the drive, the disk cartridge 1 is carried by itself, and even if vibration is applied, the disk 2 sways in the case 1d more than necessary to generate abrasion powder or the like. This is to prevent damage to information, and another important function is to prevent the information from being damaged as shown in FIG.
b is located above the case 4 and guides the case 4. By doing so, the case 4 does not sway inside the case 1d to come into contact with the disk 2 even when being carried, or used in the player or the drive, and the case 4 can be used. The engagement between the shutter 3 and the recess of the shutter 3 will not be disengaged, and malfunction will not occur. As an embodiment of the present invention, as shown in FIG. 4, an opening that is elongated in the left-right direction is provided on the front side of the disk cartridge 1, and an opening that is long in the direction orthogonal to the opening is provided on the back surface. , And also
The opening 4a of the case 4 is arranged as shown. The type having two types of driving means such as the player and the drive as in the present invention has the shape of the spindle motor, the head position,
There are also many restrictions such as the moving direction. When these are comprehensively considered in the most rational arrangement, the opening 1a and the case 4 installed in the disk cartridge 1 and the case 4 are installed.
The structure that does not match the directions in which the openings 4a are deployed is the least costly. In the case of a structure in which a plurality of shutters are provided in one package as in the present invention, it is easier to install the openings that expand in different directions as compared with the disk cartridge having the conventional structure. By doing so, it is possible to provide a disc cartridge, a player, and a drive having an extremely simple structure, although they have a wide range of functions that have never existed before, and their practical value is great.
