Abstract: A recording medium insertion and ejection device which realizes reliable insertion and ejection by simple constitution is provided. The device has a first frame, a second frame, and a latch member provided between the first frame and the second frame. The first frame is inserted in the second frame. Insertion and removal of the medium are performed to the first frame. The latch member guides the first frame to a first position where the recording medium is inserted and removed and a second position where the recording medium is used. If the medium is pushed and inserted in the first frame at the first position, the latch member will guide the first frame to the second position and maintain the first frame at the second position. If the medium is pushed again at this state, the latch member will return the first frame to the first position.

Abstract: A disk drive includes an insert-and-eject device and a disk guide unit. The insert-and-eject device is used for inserting and ejecting a disk. The disk guide unit includes a rack and a slide member connected to the insert-and-eject device in such a manner that reciprocal movement of the disk guide unit along a first direction permits the slide member to drive the insert-and-eject device to insert and eject the optical disk from the disk drive. An emergency release device is mounted on the slide member, and includes a horizontal element movable along a second direction. The rack is formed with a retention groove such that the movement of the horizontal element along the second direction permits a the horizontal element to extend within or exit the retention groove so as to couple the slide member with the rack or to disengage the slide member from the rack.

Abstract: A tray ejecting mechanism includes a stationary bezel mounted to a front surface of an ejectable tray, and a movable bezel movably attached to the stationary bezel while being biased in a front-surface direction. The stationary bezel includes a detection component positionally shiftable in accordance with an open/close position of the tray, and a switch component having a pressing portion for pressing an ejection switch on the tray and being positionally shiftable in conjunction with the detection component. When the tray is closed, the switch component is positioned such that, as the movable bezel is pushed inward, a pressing rib applies a pressing force to the pressing portion to press the ejection switch. When the tray is open, the ejection switch is prevented from being pressed by the pressing portion even if the movable bezel is pushed inward toward the stationary bezel.

Abstract: An optical disk drive (ODD) disposed in the base of a notebook computer is provided. The front end of the tray of the ODD has a panel having a body with a side edge, a guide member and a fastening member. The guide member is connected to the body, and it can move relatively to the body. The guide member has a guide channel having a first end and a second end. The fastening member has a sheet structure and a guide pillar inserted into the guide channel protruding from the sheet structure. When the guide member is moved to allow the guide pillar to move from the second end to the first end along the guide channel, the sheet structure of the fastening member is driven to protrude from the side edge to be fastened to the base of the notebook computer.

Abstract: A cartridge tray is supported to be movable relative to a frame and capable of receiving a cartridge inserted thereinto. The cartridge tray comprises a cartridge locking lever for locking the cartridge to the cartridge tray, and a lever guard for enabling the cartridge locking lever to act to lock the cartridge to the cartridge tray when the cartridge is inserted into the cartridge tray. With the provision of the lever guard, the cartridge locking lever is prevented from transitioning to a locking state even if the tray locking lever is unlocked while no cartridge is accommodated in the cartridge tray.

Abstract: An optical disc apparatus has the following arrangements. Specifically, the optical disc apparatus includes a lock pin and a lock arm. The lock pin is disposed on a side of an inner surface of a case of the apparatus, being tapered in a protruding direction thereof. The lock arm is disposed on a side of a tray of the apparatus. The lock arm, urged by a resilient member, includes a hook portion to be engaged with an inclined surface of the lock pin. When the tray has moved to a predetermined position within the case, the lock arm is engaged with the lock pin, so that the tray is held in position at the predetermined position. When an impact force equal to, or more than, a predetermined value is applied to the optical disc apparatus, the hook portion of the lock arm is displaced in the protruding direction of the lock pin along the inclined surface of the lock pin, thereby disengaged from the lock pin. Engagement of the tray is thereby released.

Abstract: A cartridge carrier has a base with a recessed plate, a top surface, and a bottom surface. An locking ejection mechanism is coupled to the base. A guide may be coupled to the top surface of the base to receive the cartridge and an interposer board may be coupled to the guide.

Abstract: An object of the invention is to provide a disc drive device capable of compulsively ejecting an optical disc by a manipulation function from the outside to prevent information recorded on the optical disc mounted on the disc drive device from being damaged. A disc drive device 1 for loading and driving an optical disc D to record information thereon or reproduce information recorded thereon comprises a manual ejection prohibiting means 41. Excluding when a carrier block 13 of a head unit B which has an optical pickup 12 is moved to a circumferential moving end of the optical disc D and a corner portion 13A of the carrier block 13 presses a driven part 43, irrespective of whether or not there is an intention for ejecting the optical disc D, even though an emergency pin P is inserted into a through-hole 3c, the optical disc D is prevented from being ejected.

Abstract: An optical disk drive includes a main body and a tray. A tray locking mechanism includes a base fixed to the tray, a locking device installed on the base for combining with or separating from a stop pin of the main body, a transmission device installed on the base for driving the locking device, and a control device installed on the base for stopping the transmission device. When the locking device combines with the stop pin of the main body, the tray can be locked to the main body, and when the transmission device drives the locking device to be separated from the stop pin of the main body, the tray can eject from the main body and the control device can stop the transmission device from rotating.
