  • Patent number: 7826172
    Abstract: A disk apparatus compatible with a disk cartridge having a large head window even with a small external size. A disk apparatus includes a cartridge holder, a pair of guide walls, a disk motor, a head, a base, first and second slider guides, first and second open/close sliders respectively having first and second engageable portions. The slider guides are provided in the cartridge holder for supporting the disk cartridge, and the sliders are slidably engaged with the slider guides. The sliders slide to allow the engageable portions to be engaged with the disk cartridge such that a distance between the engageable portions is smaller than a distance between the guide walls while the disk cartridge is inserted, and such that the distance between the engageable portions is larger than the distance between the guide walls when the disk cartridge is mounted, and thus form a window in the disk cartridge so as to allow the head to access the disk and allow the disk to be mounted on the disk motor.

  • Patent number: 7495712
    Abstract: Disclosed is a television with a disk playback feature, in which the convenience of the slot-in mechanism is preserved and a disk can be unloaded without being damaged by the lid body. A critical point is established on the path of turning of the second point of application of spring force. By the urging force of the torsion spring, the pivoting door can be forced to either open or close the slot, subject to whether or not the second point is beyond the critical point. The slot can be closed positively by the door plate before the second point reaches the critical point. Once the second point goes beyond the critical point, the pivoting door can be swung open without being thrust by the disk. Therefore, resistance during disk unloading is reduced and it can be prevented that a disk is damaged by touching with the door plate.

  • Patent number: 7340753
    Abstract: A disk drive is adapted to a disk cartridge having a rotational member and a shutter interlocked with the rotational member. The drive includes a transporting portion for transporting the cartridge and a shutter driving mechanism, which includes a rack portion engaging with a gear portion of the rotational member, and first and second driving levers supported to fit into, and turn with, first and second notched portions of the rotational member, respectively. The transporting portion includes a first cam structure for driving the first and second driving levers of the shutter driving mechanism such that the levers swing as the transporting portion moves. As the transporting portion moves, the first and second notched portions and the gear portion of the disk cartridge held on the transporting portion get engaged with the shutter driving mechanism, which then rotates the rotational member to open or close the shutter.
