Abstract: A disc changer comprises a disc storage device, a disc reproduction device and an elevation device. The disc storage device is capable of storing discs to be arranged in a apparatus main body in a stacked state. The disc reproduction device has a carriage chassis on which the first components comprising a turntable and a pickup are mounted. The elevation device is capable of elevating the disc reproduction device in the stacking direction of the disc stored in the disc storage device. A force application device is provided at a position in abutment with the carriage chassis so as to apply force to the carriage chassis, when the disc reproduction device is moved to a standby position by the elevation device. The force is applied in the opposite direction to a movement direction of the disc reproduction device toward the standby position.

Abstract: A vibration damping support mechanism for a recored data reproducing apparatus is provided which allows the apparatus to be installed in either a horizontal or vertical position without shifting the tensioning direction of damper springs. Each pair of the damping springs is mounted between a main reproducing unit and an outer casing. The two damper springs are arranged to extend in the thicknesswise and depthwise directions of the main reproducing unit respectively or arranged tilting at a predetermined angle. In the horizontal position, external vibrations are absorbed by the elastic action of one of the two damper springs and thus prevented from propagating directly to the main reproducing unit. Similarly in the vertical position, such external vibrations are absorbed by the elastic action of the other damper spring and prevented from propagating directly to the same.

Abstract: A CD player has an inner casing, a plurality of magazines provided in the casing, each of the magazines storing a plurality of CDs, a lifting device, and a movable member or casing. The movable casing has a reproducing device, a loading device for loading one of the CDs on the reproducing device, and is adapted to be lifted by the lifting device. A lock plate is slidably provided on a wall of the movable casing. A lock device is provided to drive the lock plate to engage locking teeth on the inner casing for locking the lock plate to the wall of the inner casing to prevent vertical movements of the movable member while in a playing position.

Abstract: A CD player has a magazine containing a plurality of trays each of which mounts a CD, and a moving device for moving one of the CDs between the magazine and a playback position. The starting of the operation of the moving device for moving the CD from the playback position to the magazine is detected and a CD start signal is produced. When the CD does not arrive to the magazine after a predetermined time from the production of the CD start signal, the CD is returned to the the playback position and moved from the playback position to the magazine again.

Abstract: A disk playback device includes a magazine for several disks and trays for supporting the disks, a magazine housing for the magazine, a disk playback section for playing back data recorded on a disk and a tray transport section for transporting a tray, supporting a selected disk, between the magazine and the playback section. In one embodiment, the playback device includes a disk guide for securely placing a played back disk onto its associated tray. In another embodiment, the playback device includes a disk guide for guiding disks of various diameters. In another embodiment, the playback device includes an optical detecting element for detecting whether a tray contains a disk. In another embodiment, the playback device includes a switch for detecting whether a magazine has been inserted and locked in the magazine housing. In another embodiment, the playback device includes a guide mechanism for securely guiding a disk clamper to a selected disk for playback.

Abstract: A CD player has a magazine containing a plurality of trays each of which mounts the CD, a magazine holder for holding the magazine, and a frame for vertically movably supporting the magazine holder. A pair of opposed stopper plates are provided on the frame adjacent an outlet of the tray provided on the magazine. Opposed ends of the stopper plates form a gap there-between having a width through which only one tray is passed.

Abstract: A damper has a cylindrical body having a flexible plate portion. The body is inserted into a cylindrical holder. The outer periphery of the body is secured to the holder with an adhesive so as to restrict deformation of the body caused by movement of a rod to be engaged with the flexible plate portion.

Abstract: A CD player has a magazine containing a plurality of trays each of which mounts a CD, and a magazine holder. The magazine holder has an inlet for inserting the magazine. An upper and a lower edges of the inlet has an upwardly inclined guide portion and a downwardly inclined guide portion, respectively.

Abstract: A CD player has a magazine containing a plurality of trays each of which is provided for mounting a CD, and a moving device for moving one of the CDs between the magazine and a playback position. Switches are provided for producing CD position signals each of which represents a CD position on a path of the moving tray, and a photosensor is provided for detecting the CD passing the CD position informed by said CD position signal. A display indicates whether the CD exists on the tray.

Abstract: A disk reproduction apparatus of the type capable of being displaced from a horizontal attitude to a vertical attitude or vice versa includes an outer casing; a support frame disposed inside the outer casing in a floating manner and loaded with a magazine in which a compact disk is mounted; a vibration proof mechanism disposed between the corresponding side surfaces of the outer casing and the support frame; and a pickup device disposed above the compact disk, and being movable and adapted to read the information recorded on the compact disk. The vibration proof mechanism includes a support, such as a rotating plate, pivotally secured to the side surface of the outer casing, and a spring having one end engaged with the pivotal rotating plate and the other end secured to the side surface, opposing to the side surface of the outer casing, of the support frame. Several vibration proof mechanisms may be disposed on both side surfaces of the outer casing and the support frame.

Abstract: Compensating arrangements compensate for variations in load which a disk magazine places on a drive motor. In a first arrangement, a cam slot of a predetermined spiral configuration receives driving force from a drive motor and translates the same to: an end-range force from an initial portion of the cam slot which causes the selected tray to rotate at a first speed; an intermediate-range force from a middle portion which causes the selected tray to rotate at a second speed which is higher than the first speed; and, an end-range force from a final portion which causes the selected tray portion to rotate at a third speed which is lower than the second speed.
