[0097] Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. First, refer to Figure 1 ~ Figure 3 At the same time, the configuration and structure of the first embodiment of the disk cartridge of the present invention will be described.

[0098] figure 1 It is a perspective view showing the whole disk cartridge 201, (a) shows the state in which the disk storage part 230 is closed, and (b) shows the state in which the disk storage part 230 is opened. figure 2 It is a perspective view showing the rear side of the whole disc cartridge 201, (a) shows the state in which the disc housing part 230 is closed, and (b) shows the state in which the disc housing part 230 is opened. image 3 It is an exploded perspective view showing components of the disc cartridge 201 .

[0099] As shown in these figures, the disk cartridge 201 includes a first disk storage portion 231 and a second disk storage portion 232 constituting ...

no. 2 approach

[0186] Next, a second embodiment of the disc cartridge of the present invention will be described.

[0187] Figure 19 It is an exploded perspective view showing components of the disc cartridge 202 . Such as Figure 19 As shown, the present embodiment differs from the disk cartridge 201 of the first embodiment in that the first and second lock lever portions 241 and 242 are formed of a member different from the lock lever support portion 250 . The other configurations are the same as those of the first embodiment, therefore, the same reference numerals are assigned to the same components as those of the first embodiment or corresponding components, and the overall structure of the disc cartridge 202 and the opening / closing operation of the disc housing portion 230 are omitted. .

[0188] Such as Figure 19 As shown, the locking unit 253' includes: the first and second locking lever parts 241', 242', and the locking lever supporting part 250. By installing the locking unit...

Abstract

A disk cartridge includes: a pair of disk housing portions, housing a disk entirely when put together; a supporting base member with a disk housing rotating and supporting portion for rotating and supporting the housing portions to open or shut a window to the disk such that the disk gets chucked externally, and a head can access the disk and read and write information from / on the storage layer thereof, though the window; and a locking unit including a pair of locking lever portions to keep the housing portions closed from rotating and a locking lever supporting portion supporting the lever portions rotatably and attached to the base member, wherein the pair of disk housing portions open the window wide enough to remove the disk while the lock unit is not inserted into the supporting base member, and contact with the lock unit and have their angle of rotation limited while the lock unit is inserted into the supporting base member, thereby controlling the size of the window such that the disk is unremovable.

Description

technical field [0001] The present invention relates to a disc case for storing disc-shaped data storage media such as optical discs and magnetic discs. Background technique [0002] CDs or DVDs, etc., which record or reproduce using light beams, Fropi (registered trademark) discs, etc., which use magnetism to record or reproduce, and disk-shaped data storage media such as MO or MD, which use light beams and magnetism to record or reproduce pervasive in society. In particular, erasable data storage media such as DVD-RAM and MO are stored in a box-type storage case disclosed in Patent Document 1, for example, from the viewpoint of protecting the recording surface on which data is stored. [0003] Figure 47 FIG. 1 is a perspective view schematically showing the disc cartridge disclosed in Patent Document 1. FIG. exist Figure 47 Among them, the disc cartridge 100 includes a support base member 101 that accommodates a disc 10 that is a data storage medium capable of recordin...
