A recording and/or reproducing apparatus has a disk transfer mechanism, a mechanical chassis lifting/lowering mechanism, and a gear switching mechanism. The disk transfer mechanism transfers a disk onto a disk table with a motor. The disk transfer mechanism has a rotation transmitting assembly having a gear train including a swing gear and another gear. The mechanical chassis lifting/lowering mechanism lifts and lowers a mechanical chassis with respect to the disk, which is transferred onto the disk table by the disk transfer mechanism. The gear switching mechanism brings the swing gear out of mesh with the other gear of the gear train after the disk is transferred onto the disk table by the disk transfer mechanism, thereby preventing the disk transfer mechanism from being actuated by the motor, and actuating the mechanical chassis lifting/lowering mechanism with the motor. After the disk is transferred onto the disk table by the disk transfer mechanism, the motor having actuated the disk transfer mechanism actuates the mechanical chassis lifting/lowering mechanism.

Disk recording and/or reproducing device

A structure on a base plate is simplified, and the thickness of the structure on the base plate is reduced. A disk transfer mechanism includes a housing having a disk slot. A disk is inserted from the disk slot between a base plate and a top panel of the housing. A disk transfer mechanism has a motor and a rotation transmitting assembly for transmitting rotation of the motor to the transfer rollers. The disk transfer mechanism rotates the transfer rollers to transfer the disk onto a disk table. The rotation transmitting assembly includes a base-plate rotation transmitter disposed on the base plate and a top panel rotation transmitter disposed on the top panel. Thus, the components of the rotation transmitting assembly are distributed on the base plate and the top panel.

Disk recording and/or reproducing apparatus

A plurality of switches are pressed by a single switch operating member. A disk recording and/or reproducing apparatus has a switch mechanism operable when a pair of turn arms is turned so as to be spread away from each other by a disk inserted from a disk slot. The switch mechanism includes a plurality of switches, a rotary cam rotatable in ganged relation to angular movement of the turn arms, and a switch operating lever interposed between the rotary cam and the switches for successively pressing the switches in response to rotation of the rotary cam.

A disk recording and/or reproducing apparatus has a disk centering member having a disk abutment assembly and an operating member, and angularly movably supported at a portion thereof between the disk abutment assembly and the operating member by a shaft, wherein when a transferred disk abuts against the disk abutment assembly to press the disk abutment assembly, the disk centering member is angularly moved about the shaft, and then prevented from being angularly moved by a stopper, centering the disk, and a gear switching mechanism operable by being pressed by the operating member. The disk abutment assembly has a first disk abutment for angularly moving the disk centering member by a predetermined angular interval, and a second disk abutment for angularly moving the disk centering member by an angular interval, which is substantially the same as the angular interval of the first disk abutment.

A disc changer apparatus includes a disc table, reproducing device, a first tray, a second tray, containing device, and movement device. The first tray carries a disc mounted thereon between a loading position at which a disc is loaded and a mounting position at which a disc is mounted on the disc table and between the disc mounting position and a containing position at which a disc is contained. The second tray is engaged with the first tray, to carry the first tray between the disc loading position and the disc mounting position. The containing device stacks and contains the first trays in a stacking direction substantially perpendicular to principal planes of discs mounted on the first trays. The moving device moves at least one of the first trays contained in the containing device in one direction based on the stacking direction, to form a containing space for containing the first tray located at the disc mounting position on the side, opposed to the side of the one direction, of the containing device.

Disc changer apparatus

An apparatus for recording and/or reproducing a disc-shaped recording medium. A medium is placed on each of a plurality of placement members. The members are stacked and housed in a housing unit. An elevating mechanism elevates the housing unit in the direction almost parallel to the stack direction of the members. A carrying mechanism carries one of the members among a position where a medium can be placed or ejected to/from the member, a position where the member is housed in the housing unit and a position where the medium placed on the member is loaded to the 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 mechanism and the elevating mechanism. A photodetector detects the presence/absence of the medium on the members in the housing unit.
