Abstract: A library apparatus includes a storage shelf including a first movable shelf and a second movable shelf each having a plurality of rows and columns of cells in which storage mediums are to be stored, a drive unit being disposed such that a direction of access to the drive unit for inserting/ejecting of one of the storage mediums is the same as a direction of access to the storage shelf, a conveyor for conveying one of the storage mediums between the storage shelf and the drive unit, and a movement control unit for controlling to lift a specific row of cells of the first movable shelf to produce a space and to move horizontally a specific row of cells of the second movable shelf to a position in the space accessible by the conveyor.

Abstract: A library device includes: cells each containing a storage medium in a first or a second manner; a medium drive accessing and containing the medium differently from a manner of placing the medium in at least one of the cells; and a medium-transferring unit including a housing section housing the medium, and moving the housing section between the cells and the medium drive to transfer the medium. The unit includes: a support member supporting the housing section pivotably between a first and a second postures meeting the first and second manners; a movement-controlling system moving the support member so that the housing section faces the cells and medium drive; a medium-transferring system transferring the medium; a biasing member biasing the housing section toward the first posture; and a posture-changing member interfering with and thereby pivoting the housing section from the first posture to the second posture resisting the biasing member.
