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.

Dependent claims

A disk loading device comprising:

at least one roller for transferring a disk;
at least one roller drive means for rotating said at least one roller around an axis of said at least one roller to transfer said disk by a force applied by said at least one roller to said disk upon a rotation of said at least one roller when a peripheral surface of said at least one roller is contacted with an outer peripheral surface of said disk;
at least one roller movement means for moving said at least one roller toward said disk to contact said peripheral surface of said at least one roller against said outer peripheral surface of said disk to contact said outer peripheral surface of said disk at a predetermined pressure,
said at least one roller movement means including a frictional engagement means for providing a slippable coupling between said roller movement means and said roller drive means, thereby enabling a pressing of said peripheral surface of said roller against said outer peripheral surface of said disk at said predetermined force,
said frictional engagement means including an input part coupled to said roller drive means and an output part rotatably supporting said axis of said roller and frictionally engaged with said input part.

2 more elements

A disk loading device comprising:

a pair of rollers for transferring a disk;
roller drive means for rotating said pair of rollers in opposite directions around axes of said pair of rollers to transfer said disk by a force applied by said pair of rollers to said disk upon a rotation of said pair of rollers when peripheral surfaces of said pair of rollers are contacted with an outer peripheral surface of the disk;
roller movement means for moving said pair of rollers toward and away from each other to contact said peripheral surfaces of said pair of rollers against said outer peripheral surface of said disk to contact said outer peripheral surface of said disk at a predetermined pressure,
said roller movement means including a pair of frictional engagement means for providing a slippable coupling between said roller movement means and said roller drive means, thereby enabling a pressing of said peripheral surfaces of said pair of rollers against said outer peripheral surface of said disk at said predetermined force,
each of said pair of frictional engagement means including an input part coupled to said roller drive means and an output part rotatably supporting one of said axes of said pair of rollers and frictionally engaged with said input part;
and
ejection means, comprising a pair of ejection arms, for moving said pair of ejection arms toward and away from each other;
wherein said pair of rollers are brought by said roller movement means into contact with said outer peripheral surface of said disk so as to transfer said disk by rotational drive forces of said pair of rollers, and said pair of ejection arms are urged by said ejection means against the outer peripheral surface of said disk so as to eject said disk.

5 more elements

A disk loading device comprising:

a pair of rollers for transferring a disk;
roller drive means for rotating said pair of rollers by the rotational drive force of said motor around axes of said pair of rollers to transfer said disk by a force applied by said pair of rollers to said disk upon a rotation of said pair of rollers when peripheral surfaces of said pair of rollers are contacted with an outer peripheral surface of said disk;
and
a pair of roller movement mechanisms for respectively moving said pair of rollers toward and away from a path of travel of said disk to contact said peripheral surfaces of said pair of rollers against said outer peripheral surface of said disk to contact said outer peripheral surface of said disk at a predetermined pressure,
each of said pair of roller movement mechanisms including a frictional engagement means for providing slippable coupling between said each of said pair of roller movement mechanisms and said roller drive means, thereby enabling a pressing of said peripheral surface of said roller against said outer peripheral surface of said disk at said predetermined force,
each of said frictional engagement means having an input part coupled to said roller drive means and an output part rotatably supporting said axis of said roller and frictionally engaged with said input part.
