Abstract: A head-mounted display apparatus has a frame with a left member, a right member, and a centralized member. The centralized member is positioned in between the left member and the right member. Further, the left member adheres to a left side of a head of a user. Moreover, the right member adheres to a right side of the head of the user. Additionally, the head-mounted display apparatus has a display area operably attached to the centralized member. Further, the head-mounted display apparatus has a processor integrated within the frame. The processor generates an immersive experience for display on the display area. Finally, the head-mounted display apparatus has a removable input controller positioned within the left member or the right member. The removable input controller navigates the immersive experience based on one or more inputs received from the user at the removable input controller after the removable input controller is removed from the left member or the right member.

Abstract: An integrated reproducing/recording apparatus (10) comprises a magnetic reproducing/recording device (11), an optical reproducing/recording device (12) and a spindle (13) located therebetween. The magnetic reproducing/recording device has a magnetic disk (111) with a center hole (113) and a magnetic pickup head (112). The optical reproducing/recording device has an optical disk (121) with a center hole (123) and an optical pickup head (122). The spindle has fixtures at each end thereof. The magnetic disk or the optical disk is selectively fixed on the spindle.

Abstract: An optical disc changer includes a main body, a tray installed in the main body to be capable of sliding, a roulette rotatably installed at the tray and where a plurality of optical discs are accommodated, an optical pickup device to selectively reproduce one of the optical discs accommodated on the roulette, a drive gear member installed at the main body, rotated by being connected to a drive unit, and selectively engaged with a rack gear member formed on the bottom surface of the tray, and a tray gear unit installed adjacent to the drive gear member and having a tray gears selectively engaged with the rack gear member and the drive gear member.

Abstract: A disk recording and/or reproducing apparatus recording and/or reproducing information on and/or from anyone of a plurality of disk-like recording mediums. Freedom in design is improved by effectively utilizing spaces in which respective portions and mechanisms of the apparatus are disposed. In the apparatus, a first planet gear and second planet gear meshed with a racked portion are switched, whereby the disk tray is moveable between a loading position at which the disk tray is loaded into the apparatus and an eject position at which the disk tray is ejected to a location outside the apparatus body.

Abstract: An apparatus for recording and/or reproducing a medium includes an elevating mechanism elevating a housing unit in which members are stacked and stored. A carrying mechanism carries at least one of the members between a position where the member is housed in the housing unit and a position where a medium on the member is loaded to a recording and/or reproducing unit. A driving source drives both the carrying mechanism and the elevating mechanism. A switching mechanism selectively supplies a driving force from the driving source to the carrying and elevating mechanisms. A rack part is formed in the member. The carrying mechanism includes a feed gear and an arm. The feed gear comes into engagement with the rack part and is rotatably attached to the arm. The switching mechanism swings the arm so that the feed gear is disengaged from the rack part when the elevating mechanism is driven.

Abstract: The present invention relates to a disc ejecting apparatus for quickly ejecting a disc by utilizing a pick-up drive motor. A slip mechanism is provided in a first route leading from the pick-up drive motor to a pick-up, and a switching mechanism is provided in a second route leading from the pick-up motor to a disc ejecting mechanism.

Abstract: An optical disc changer includes a main body, a tray installed in the main body to be capable of sliding, a roulette rotatably installed at the tray and where a plurality of optical discs are accommodated, an optical pickup device to selectively reproduce one of the optical discs accommodated on the roulette, a drive gear member installed at the main body, rotated by being connected to a drive unit, and selectively engaged with a rack gear member formed on the bottom surface of the tray, and a tray gear unit installed adjacent to the drive gear member and having a tray gears selectively engaged with the rack gear member and the drive gear member.
