Cartridge overinsertion protection for cartridge library

Abstract

Cartridges ( ) are loaded into or retrieved from an automated media library ( ) either singly through an entry/exit port module ( ), or by opening a library door ( ) and inserting/removing a cartridge magazine ( ) from a magazine cavity ( ) of the library. Structures are provided for precluding against overinsertion of a cartridge. An entry/exit port cartridge overinsertion protection assembly ( ) is provided to prevent overinsertion of a media cartridge loaded into the entry/exit port module. The entry/exit port cartridge overinsertion protection assembly includes a cartridge restraint member ( ) which is pivoted away from a cartridge restraint position by a cartridge transport device ( ) when the transport device seeks to obtain or deposit a cartridge at the entry/exit port. A cartridge restraint assembly ( ) is also provided to guard against overinsertion of a cartridge stored in a cartridge magazine. The cartridge restraint assembly which guards against overinsertion of a cartridge stored in a cartridge magazine is responsive to movement of a library door. Upon movement of the door from a door closed position to a door open position, the cartridge restraint assembly responsively moves into a cartridge restraint position to prevent over positioning of a cartridge situated in the cartridge magazine.
