Abstract: A loading device for a disc-shaped recording medium, such as an optical disc, includes a recording/reproducing unit, a loading member, a transport mechanism, a control mechanism and a chuck mechanism. The recording/reproducing unit has a rotating driving mechanism for rotationally driving the disc-shaped recording medium and a head for recording and/or reproducing information signals on or from the disc-shaped recording medium. The loading member is arranged facing the recording/reproducing unit on the chassis for movement along the chassis surface. The transport mechanism transports the disc-shaped recording medium introduced into the apparatus as far as the recording/reproducing unit. The control mechanism releases the disc transport operation by the transport mechanism by the loading member being moved on the chassis. After the transport operation of transporting the disc-shaped recording medium by the transport mechanism is discontinued by the control mechanism, the chuck mechanism chucks the disc-shaped recording medium transported by the movement of the loading member on the chassis in cooperation with the rotating driving mechanism of the recording/reproducing unit.

Abstract: A recording and/or reproducing apparatus for recording and/or reproducing information signals with the use of a tape cassette is provided with a pair of reel shafts, each having an engaging member mounted with a bias towards the end of the supporting shaft, and a tape cassette transfer mechanism adapted for shifting the tape cassette inserted by way of the cassette inserting opening in a first direction normal to the reel shafts and guiding or loading the tape cassette for inserting and engaging the reel shafts with a pair of tape reels within the tape cassette. When at least the tape cassette transfer mechanism is set at a position facing the cassette inserting opening, the tape cassette is moved by the tape cassette transfer mechanism towards the proximal side of reel shafts, to reduce the displacement in the second direction of the tape reel of the tape cassette by the tape cassette transfer mechanism to a value lesser than the thickness of the tape cassette to reduce the thickness of the apparatus. After completion of the tape cassette loading by the tape cassette transfer mechanism, the tape cassette is partially exposed to the cassette inserting opening to prevent a second tape cassette from being introduced into the cassette inserting opening after completion of loading of the first-mentioned cassette.

Abstract: In a compact disc player (1A) in order to protect a disc (D) upon unloading and loading, at least one pair of rollers (40a, 40b) is provided for holding therebetween and transporting the disc (D) inserted thereinto. The rollers (40a, 40b) are of tapered shape, so that the diameter of each roller (40a, 40b) is relatively small over a central portion thereof and gradually increases therefrom to each end, so each roller (40a, 40b) contacts only with the peripheral edge portion of the inserted disc (D).

Abstract: A recording and/or reproducing apparatus for recording and/or reproducing information signals with the use of a tape cassette (300) is provided with a pair of reel shafts (6, 7), each having an engaging member (6b, 7b) mounted with a bias towards the end of the supporting shaft, and a tape cassette transfer mechanism adapted for shifting the tape cassette inserted by way of the cassette inserting opening (2a) in a first direction normal to the reel shafts and guiding or loading the tape cassette for inserting and engaging the reel shafts with a pair of tape reels (302, 303) within the tape cassette. When at least the tape cassette transfer mechanism is set at a position facing the cassette inserting opening, the tape cassette is moved by the tape cassette transfer mechanism towards the proximal side of reel shafts, to reduce the displacement in the second direction of the tape reel of the tape cassette by the tape cassette transfer mechanism to a value lesser than the thickness of the tape cassette to reduce the thickness of the apparatus. After completion of the tape cassette loading by the tape cassette transfer mechanism, the tape cassette is partially exposed to the cassette inserting opening to prevent a second tape cassette from being introduced into the cassette inserting opening after completion of loading of the first-mentioned cassette.
