Abstract: There is provided a disk loading apparatus capable of improving the stability in the centering operation at low cost only by changing the shape of the guide groove without adding extra parts or complicated structures. The disk loading apparatus includes a feed roller 2, a disk arm 4 adapted to move back and forth between an initial position where a disk 100 that is drawn by the feed roller 2 is received and a retracted position that corresponds to a chucking position for the disk, and a guide groove 5. The feed roller 2 has a function of centering the disk 100. The guide groove 5 includes slant wall surfaces 57 with the groove width therebetween decreasing progressively in the retracting direction of the disk arm 4, and receiving surfaces 58 for limiting the tilt angle of the disk arm 4.

Abstract: In guide grooves formed at both side edges of a lower face of a tray and fitted to a pair of left and right guide members of a cabinet, the guide groove substantially in a U-like shape on one side is inserted with a front end portion of an elastic plate integrally projected at a front portion of the cabinet, a recess portion is formed at a portion of one side face of the guide groove 12 opposed to the elastic plate in a state of containing the tray into the cabinet, and formed such that by bringing the one side face of the guide groove 12 into elastic contact with the elastic plate opposed to the recess portion in moving the tray forward, other side face of the guide groove is brought into contact with reference guide faces of the guide member on one side to thereby prevent the tray from being inclined.

Abstract: In the configuration including: a tray drive mechanism for reciprocally moving a tray with a drive motor as a power source; and a motor drive unit for driving the drive motor, after the movement of the tray in a retracted position is started by applying a first drive voltage to the drive motor, when a predetermined time duration elapses after the time at which the tray is deemed to have moved to the ejected position, the motor drive unit gradually lowers a voltage applied to the drive motor, from the first voltage toward 0V.
