【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 is a perspective view of a cartridge according to the present invention, FIG. 2 is a top view of the cartridge, FIG. 3 is a sectional view of the cartridge, FIG. 4 is a sectional view of a RAM portion of the cartridge, and FIG. FIG. 6 is a schematic side sectional view of the reproducing apparatus using the cartridge, FIG. 7 is a schematic side sectional view of the reproducing apparatus using the cartridge, and FIG. 8 is a perspective view of a shutter opening / closing mechanism section of the reproducing apparatus. It is a figure.

The cartridge 1 has a single-plate-shaped cartridge body 2 whose four corners are slightly thicker than the thickness of the disc like a CD case, and a disc-shaped recess 2 a formed on the surface of the cartridge body 2 has a CD or the like. The disk 3 is mounted so that its recording surface 3a faces the cartridge body 3 side and the label surface 3b faces outward (see FIG. 3).

As shown in FIG. 3, the disc 3 is attached to the cartridge body 2 by mounting a cylindrical hub 4 for chucking the reproducing device, and forming a recess 4a formed on the outer peripheral surface of the hub 4 into the cartridge. By fitting the protrusion 2b formed on the inner peripheral surface of the main body 2, the disk 3 is attached to the cartridge main body 2 in a rotatable and non-separable manner.

A botch 2c that contacts an unrecorded portion of the disc 3 is formed on the disc mounting surface side (front side) of the cartridge body 2 so that the recording surface 3a of the disc 3 and the cartridge body 2 do not rub directly. . Further, the cartridge body 2 is formed with a through hole 5 for reading recorded information recorded on the recording surface 3a of the disk 3, and a shutter 6 for opening and closing the through hole 5 is slidably attached.

In two empty spaces in the four corners of the cartridge body 2, as shown in FIGS. 4 and 5, a RAM 7 which is a memory means for saving data, and an electrode for data access to the RAM 7 are provided. 8; a printed circuit board 9 for RAM 7; and a battery 10 for RAM backup. The electrode 8 is attached to the printed board 9, and a hole is formed on the back surface of the cartridge body 2 so as to correspond to the electrode 8.

A transparent cover 12 can be detachably attached to the cartridge body 2. The cover 12 is formed with claws 12a that engage with the cartridge body 2 on the inner surfaces of both sides, and the claws 12a are bent outward when the cover 12 is removed. Supports 12b are formed at four positions on the cover 12 so that the instruction manual 13 can be held on the inner surface.

On the other hand, in the reproducing device (player device) 21, a cover 23 that covers the upper surface of the player main body 22 having a storage portion 22 a for storing the cartridge 1 is attached so as to be openable and closable. The storage portion 22a is formed wider than the cartridge 1 so that the operator's finger can be easily inserted.

In addition, as shown in FIG. 7, a chucking 24 that fits into a center hole 4b, which is the center of the hub 4 of the disc 3 mounted on the cartridge 1, is provided in the storage portion 22a of the player main body 22. An electrode 25 that can come into contact with the electrode 8 of the cartridge 1 is provided so as to be movable up and down, and the electrode 25 has a structure that moves up and down in conjunction with opening and closing of the cover 23.

Further, as shown in FIG. 8, when the cover 23 is closed in the player main body 22, the player main body 22 enters the storage portion 22 a and engages with the shutter 6 of the cartridge 1 to attach the shutter 6 to the shutter 6. A shutter opening / closing claw 26 for sliding is provided.

The operation of the cartridge 1 and the reproducing apparatus 21 configured as above will be described. Since the cartridge 1 uses the single-plate-shaped cartridge body 2 that protects only the recording surface of the disc 3, the cover member is unnecessary compared to the case where the entire disc 3 is covered, and the thickness is thin. The cost is low, and it is easy to make the outer diameter the same as the existing disk case, and the compatibility with the existing disk can be obtained.

Further, since the cartridge 1 has the RAM 7 built in the cartridge main body 2, it is possible to store data in the middle of the game, and since the disc 3 cannot be separated from the cartridge body 2, initial data is recorded. This saves the trouble of having to carry both the disc and the medium on which the data for storage is recorded (including the playback device), and the data can be used regardless of the playback device. Furthermore, since the cartridge body 2 and the disk 3 cannot be separated, it is possible to avoid a discrepancy between the contents of the disk 3 and the contents of the RAM 7.

Next, in the reproducing device 21, the cartridge 1 is loaded into the housing portion 22 a of the player main body 22 and the cover 23 is closed, so that the electrode 25 that comes into contact with the electrode 8 of the RAM 7 has the electrode 6 inside the housing portion 22 a. The opening / closing claw 26 also advances to the position of engagement with the shutter 6 of the cartridge 1 and opens the shutter 6 in the storage portion 22a. Further, when the cover 23 is closed, both the electrode 25 and the opening / closing claw 26 are retracted to the retracted position in the player main body 22.

This prevents the operator from coming into contact with the electrode 25 or the opening / closing claw 26 while the cover 23 is open.
