In a disk carrying device including a first idle gear rotatably supported by a lower chassis and a second idle gear for contacting and separating from the first idle gear to perform a rotation operation, the second idle gear and a roller gear meshing therewith are rotatably supported by a feed plate to cause the second idle gear to contact and separate, from below, from the first idle gear rotatably supported by the lower chassis. Because of this configuration, in disk insertion, a downward force F1 acts on the second idle gear and a pushing pressure of the feed roller to a disk D decreases. In disk ejection, an upward force F2 acts on the second idle gear and the pushing pressure of the feed roller to the disk D increases.

The clamping eccentric is moveable from the locking position thereof into the unlocking position thereof. A pretensioned compression spring is provided, which is supported at one end thereof on an arm of the clamping eccentric in a manner spring-loading the latter into the locking position thereof and, at the other end thereof, acting upon the latch in the unlocking direction.

A disk carrying device and an optical disk recording / reproducing device. The disk carrying device comprises a first idle gear rotatably supported on a lower chassis and a second idle gear rotatingly operated by coming into contact with or separating from the first idle gear. The second idle gear and a roller gear meshed with the second idle gear are rotatably supported on a feed plate, and the second idle gear is brought into contact with or separated from the first idle gear, from the underside, which is rotatably supported on the lower chassis. By this, when a disk is inserted, a downward force F1 acts on the second idle gear, and the pressing force of a feed roller on the disk (D) is decreased and, therefore, the rotating load of a disk carrying motor can be reduced when the carrying of the disk is completed. When the disk is discharged, an upward force F2 acts on the second idle gear and the pressing force of the feed roller on the disk (D) is increased and, therefore, the disk (D) can be smoothly discharged even if the disk (D) is deflected.
