Abstract: A disk drive includes: a pair of guide walls, which is arranged in the vicinity of the holder opening of a cartridge holder to define a direction in which a disk cartridge is supposed to be inserted; a first opening/closing lever, which has a first engaging portion that engages with a portion of the disk cartridge and which rotates while the disk cartridge is being inserted or ejected; and a second opening/closing lever, which has a second engaging portion that engages with another portion of the disk cartridge and which rotates while the disk cartridge is being inserted or ejected. The pivots of the first and second opening/closing levers are arranged opposite to the holder opening. The first and second opening/closing levers rotate so as to leave a broader gap between the first and second engaging portions than between the guide walls when the drive gets loaded with the disk cartridge, thereby opening a window in the disk cartridge.

Abstract: A disk cartridge according to the present invention includes a case body 10, a shutter 11 and an elastic member 7. The case body 10 has a head window 12, which reaches a side surface, and a shutter opening groove 24 with a holding recess 26 at the bottom. The shutter portion 11 is subjected to the elastic force applied by the elastic member 7 so as to close the head window 12, thus preventing a record/reproduce head from interfering with the case body 10 and reducing the width of the disk cartridge. Also, a gripping member, provided for a disk drive to prevent the disk cartridge from popping out due to the reactive force caused by the elastic member 7, neither disengages itself from the holding recess 26 easily nor interferes with the head.

Abstract translation: 根据本发明的盘盒包括壳体10，挡板11和弹性构件7。 壳体10具有到达侧面的头部窗口12和在底部具有保持凹部26的活门开口槽24。 挡板部11受到由弹性部件7施加的弹力，以封闭头部窗口12，从而防止记录/再现头部与壳体10干涉并减小盘盒的宽度。 此外，为了防止由于弹性构件7引起的反作用力而使盘盒弹出而设置的盘驱动器的夹持构件既不容易脱离保持凹部26，也不会干扰头部。

Abstract: A disk recording/reproducing apparatus 101 includes: a chassis 103 rotatably supporting a holder 102 for storing a disk cartridge; an eject lever 105 disposed in the chassis movably in an insertion/removal direction of the disk cartridge and movably in a direction toward or away from the chassis, the eject lever being rotated by being pushed by the disk cartridge 1 inserted into the holder; and cartridge drop preventive means 221 for preventing the disk cartridge 1 ejected by the eject lever 105 from dropping from the cartridge holder 102. The cartridge drop preventive means 221 is formed from a flat spring disposed on one side surface 102b of the holder and makes a sliding contact with one side surface 3b of the disk cartridge during unloading of the cartridge so as to give the disk cartridge a braking force. This arrangement can prevent the disk cartridge from jumping out and dropping off from the cartridge holder during ejection.

Abstract: A holder pivotally supported on a chassis for supporting a cartridge which is provided with a shutter biased by a spring in a closing direction. A slide member mounted on the holder is reciprocatingly movable between a first position where an opening piece pushes the shutter open with the loading of the cartridge into the holder and a second position where the latch engages the cartridge after moving from the first position toward the cartridge loading direction. A release mechanism is disposed between the chassis and the holder for disengaging the latch from the cartridge when the cartridge is unloaded from the holder. The cartridge as disengaged and in contact with the opening piece is moved by the spring in the unloading direction.
