Disk cartridge and device to which disk cartridge is inserted
View Patent ↗A disk cartridge, which is easy to handle, is provided. The disk cartridge includes a cartridge main body having: an opening facing a disk; and a shutter for opening and closing the opening. A part of the cartridge main body is formed in an approximately semicircular shape. Such a shape allows a user to easily know an insertion direction. Moreover, since the cartridge main body does not have any corners, the insertion into a drive device is simplified. The shutter is provided pivotably for the cartridge main body. Any one of a plurality of types of medium can be provided in the disk cartridge. When the disk cartridge is inserted into an external device such as the drive device, the device receives a signal indicating the type of medium, which is transmitted through an electric terminal, so as to perform a process in accordance with the type of medium.

a cartridge main body; and
a round plate-shaped disk rotatably housed within the cartridge main body,
wherein the cartridge main body includes an opening facing the disk and a shutter which opens and closes the opening,
wherein a part of the cartridge main body is formed in an approximately semicircular shape,
wherein the cartridge main body includes an electric terminal adapted to electrically couple the disk cartridge and a drive device when the disk cartridge is inserted in the drive device,
wherein the drive device receives an electrical signal indicating the type of medium from the disk cartridge, and
wherein the drive device executes a process in accordance with the type of medium.
2. The disk cartridge according to claim 1 , wherein
the cartridge main body has the electric terminal in a region other than a region in the approximately semicircular shape.
3. The disk cartridge according to claim 1 , wherein
the shutter has the same axis of rotation as that of the disk and is pivotably provided for the cartridge main body.
4. The disk cartridge according to claim 2 , wherein
the shutter has the same axis of rotation as that of the disk and is pivotably provided for the cartridge main body.
5. The disk cartridge according to claim 1 , wherein
the cartridge main body has a groove formed in a direction in which the disk cartridge is inserted into the drive device, the groove having an end at a part of a circumferential portion of the region in the approximately semicircular shape; and
the shutter has a projecting portion protruding toward the groove.
6. The disk cartridge according to claim 2 , wherein
the cartridge main body has a groove formed in a direction in which the disk cartridge is inserted into the drive device, the groove having an end at a part of a circumferential portion of the region in the approximately semicircular shape; and
