Disk transportation device and disk storage system

A disc conveying device includes a pair of rails positioned on opposite sides across a disc-shaped recording medium transported in the lead-in direction or ejecting direction in a direction orthogonal to a center axis direction, and extending in the direction of the conveyed disc-shaped recording medium; link arms that are turnably supported to a base chassis, are turnable as to the pair of rails, and move in parallel in a direction of separating the rails from the peripheral face of the disc-shaped recording medium; conveying rollers that convey the disc-shaped recording medium by being supported by the rails, and touch the peripheral face of the disc-shaped recording medium with at least one conveying roller rotating; and an ejecting lever that is turnable as to at least one of the rails, by which turning the peripheral face of the disc-shaped recording medium is pressed, and the disc-shaped recording medium is conveyed.

A disc cartridge includes a case body for receiving disc-shaped recording media in an axial direction of a central shaft so that first and second shells respectively having a base surface portion parallel to a recording surface of the disc-shaped recording media are coupled separated by axial engagement/disengagement; and a lock lever supported perpendicular to the axial direction in the case body and locking the shells coupled. The shells are separated to form a disc insertion/extraction hole for the insert or discharge of the disc-shaped recording media into/from the case body. A support shaft serving as a pivoting point of the lock lever is installed to the case body. The lock lever includes a supported portion supported by the support shaft, a lock portion protruding from the supported portion and locking the shells, and a balance portion protruding from the supported portion approximately opposite to protrusion of the lock portion.

Disc cartridge

A cartridge transporting device includes: a cartridge holder in which a cartridge receiving a recording medium is inserted and which holds the inserted cartridge; a supporting frame that supports the cartridge holder to be freely move between an insertion position and a drawn-in position; a locking member that moves between a locking position and a non-locking position, moves to the locking position, and locks the cartridge holder at the insertion position; a holder driving member that is movable in a predetermined direction and moves the cartridge holder between the insertion position and the drawn-in position; and a moving mechanism that moves the holder driving member in the predetermined direction, wherein when the cartridge holder starts to move from the insertion position to the drawn-in position, the holder driving member moves such that the cartridge holder locked by the locking member is unlocked.

Cartridge transporting device
