1. Field of the Invention
The present invention relates to recording medium cartridges in which a recording medium such as a disk medium is rotatably accommodated within the housing.
2. Description of the Related Art
The present invention will be described in further detail with reference to the accompanying drawings wherein:
FIGS. 1A to 1F are front, rear, right side, left side, plan, and bottom views showing a “clik!™ (cartridge)” to which the present invention is applied;
FIG. 2 is a plan view showing a recording medium cartridge constructed in accordance with a first embodiment of the present invention;
Embodiments of the present invention will hereinafter be described with reference to the drawings. In the first embodiment to the twenty-ninth embodiment, the present invention is applied to a “clik!™”, which is a recording medium cartridge with a disk medium in current use. Initially, a description is given of the current clik!™ (existing cartridge) shown in FIG. 1.
In the figure, the existing cartridge 1 includes a housing 10, which comprises an upper metal shell half 11, a lower metal shell half 12, a resin part 13, a shutter 14 with a shutter knob 14a mounted thereon, a shutter lock 15 for locking the shutter 14 at a shutter closing position, and an urging member (not shown) for urging the shutter 14 toward the shutter closing position. The resin part 13, the shutter 14, and the shutter lock 15 are disposed between the upper and lower metal shell halves 11 and 12. In the interior of the housing 10, a magnetic disk 17 fixedly attached on a center hub 16 is rotatably accommodated. The right side surface of the housing 10 is provided with a shutter slot 10a, through which part of the shutter lock 15 is exposed. The left side surface of the housing 10 is provided with a positioning notch 10b, which is engaged by the engagement member of a cartridge drive (not shown) for the existing cartridge 1 to ensure the positioning of the existing cartridge 1 when it is inserted into the existing cartridge drive.
The lower metal shell half 12 is provided with a spindle hole 12a into which a spindle in the cartridge drive is inserted, and a shutter-knob slot 12b along which the shutter knob 14a is movable.
