Abstract: The disk changer comprises a first rack member supporting on its one end side a latch pawl adapted to latch a pin, and a second rack member supporting on its other end side a latch pawl adapted to latch the pin, the first and second rack members being slidably supported in parallel with each other. After the first rack member transfers a tray by a predetermined distance, latching of the tray thereon is switched over from the first rack member to the second rack member. The tray is then further transferred by the second rack member.

Abstract: There is disclosed a disk loading device capable of transferring a disk without damaging a face of the disk. The disk loading device includes a roller movement mechanism for moving a roller toward and away from a path of transfer of the disk, and a roller drive mechanism for rotating the roller. The roller is brought by the roller movement mechanism into contact with an outer peripheral surface of the inserted disk, so that the disk is transferred by the rotational drive force of the rotating roller in a predetermined direction. For discharging the disk, the outer peripheral surface of the disk is urged by an eject mechanism operatively connected to the roller drive mechanism, so that the disk is ejected.

Abstract: The present invention relates to fast forward (FF) and fast rewind (REW) mechanism of a magnetic recording and reproducing apparatus. This mechanism has: first and second arms to which first and second gears for tranferring the rotational forces of first and second flywheels to first and second reel axes are rotatably supported; a driving plate whose rotating direction differs in accordance with the running direction of a magnetic tape; and an FF lever and an REW lever for rotating this driving plate, wherein the driving plate is rotated by operating the FF or REW lever, the first or second arm is rotated by this driving plate, the rotation of first or second flywheel can be transferred to the first or second reel axis, and the FF operation is performed when operating the FF lever and the REW operation is executed when operating the REW lever irrespective of the running direction of the magnetic tape.
