Claim:
A library device comprising: a frame; a plurality of cells provided in the frame and each containing a storage medium removably in at least one of a first placement manner and a second placement manner different from the first placement manner; a medium drive provided in the frame and accessing the storage medium contained in the cell; and a medium-transferring unit that includes a housing section housing the storage medium removably, and moves the housing section between the plurality of cells and the medium drive, thereby transferring the storage medium between the plurality of cells and the medium drive, wherein the medium drive contains the storage medium in a second-type placement manner different from a first-type placement manner that is, of the first placement manner and the second placement manner, a manner of placing a storage medium contained in at least one of the plurality of cells, and the medium-transferring unit further includes: a support member that supports the housing section pivotably between a first posture in which the housing section houses the storage medium in one of the first placement manner and the second placement manner and a second posture in which the housing section houses the storage medium in the other of the first placement manner and the second placement manner; a movement-controlling system that causes the support member to move to a position where the housing section faces each of the plurality of cells and the medium drive; a medium-transferring system that transfers the storage medium between each of the plurality of cells and the housing section and between the medium drive and the housing section; a biasing member that biases the housing section to be in the first posture; and a posture-changing member that interferes with the housing section when the housing section moves and reaches a predetermined position, and causes the housing section to pivot from the first posture to the second posture by resisting a biasing force produced by the biasing member.
