Abstract: A display connector includes a body having a mounting portion on one surface, a detachably installed display member, a pair of rotation pins in the mounting portion, a pair of rotating fixing brackets for the rotation pins, a locking feature, an unlocking feature, and a rotating light emitter coupled to either of rotation pin with a laser diode array. Each diode in the array independently radiates light according to a driving signal. A light receiving module in the display faces the light emitting module when the display is mounted on the body, and has a photo diode array for receiving the output of the laser diode array. The picture signal is transmitted from the body to the rotatably-connected display using the light.

Abstract: A disk cartridge includes a case accommodating a disk, a cover installed at the case to be capable of being open and shut and having a hole formed thereon to be open to an outside of the cover, a shutter installed under the disk in the case to be capable of moving to open and shut an opening formed on the case, and a clamping member installed at the cover to seal the hole to clamp the disk. Thus, since the clamping member blocks the hole of the cover connected to the outside of the cover, possibility of intrusion of dust into the disk cartridge is reduced. Also, since there is no need to install the clamping member at the disk drive, the disk drive can be made simplified and slim.

Abstract: A disk drive including a tray on which a disk cartridge is mounted and is loaded into and unloaded from a main body; a guide formed on the tray; and an opening and closing member installed to be elastically connected to the guide. The opening and closing member has a second gear that rotates a rotating wheel by meshing with a first gear; and a first protrusion formed on one end of a second gear and to temporarily rotate the rotating wheel so that the first and second gears can mesh. The guide pushes the first protrusion during loading/unloading of the tray so that the first protrusion and the latch do not come in contact with each other.

Abstract: A disk cartridge includes a case accommodating a disk and having a first hole, a cover installed at the case and having a second hole open to an outside of the cover, a shutter installed to be capable of moving with respect to the case disposed under the disk to open/shut the first hole formed on the case, and a plurality of protruding portions provided at the shutter to support a non information area provided at an outer circumferential side of the disk and having inclined surfaces inclined at a predetermined angle. When the shutter is opened, the disk descends along the inclined surfaces. When the shutter is shut, the disk ascends along the inclined surfaces to closely contact a portion of the cover disposed around the second hole of the cover. Thus, since the shutter contacts only a non-information area of the disk, an information area of the disk can be safely kept from being damaged during an operation of opening/shutting the first hole.
