A library apparatus is capable of enhancing the dimensional accuracy of locker frame structures to allow an accessor to surely carry out the insertion/extraction of a cartridge into/from a storage unit or a deck. Each of the locker frame structures is made up of a top board, a base and sheet metal columns vertically standing between corner portions of the top board and the base. Each of the sheet metal columns is fixedly welded to the top board and the base from the inside of the locker. The library apparatus is applicable to a large-capacity external storage system storing a large number of cartridges such as magnetic tape cartridges and optical disk cartridges.

[ What is claimed is:] [7.]7. A library apparatus comprising:(A) a plurality of lockers adapted to be linked together as a unit, said plural lockers including(i) a plurality of frames, each having a substantially rectangular parallelepiped shape and each disposed to a respective one of said plurality of lockers, for defining both an external form and an internal passage of said library apparatus,(ii) at least one storage rack, disposed in at least one of said plurality of frames, for storing a number of cartridges, each accommodating a storage medium,(iii) at least one deck, disposed in at least one of said plurality of frames, for carrying out access to the storage media in the individual cartridges, and(iv) at least one accessor, housed in at least one of said plurality of frames, for transferring the individual cartridges between said storage rack and said deck; and(B) means, attached to an inside of at least one of said plural frames so as to go through said plurality of frames, for allowing said accessor to move through said passageway of said library apparatus by guiding said accessor;each of said plurality of frames further having:(i) a horizontal base having a substantially rectangular shape,(ii) sheet metal columns standing at corners of said base, and(iii) a top board substantially identical in shape to said base and mounted on said sheet metal columns,each of said base and said top board having positioning holes in its corners,each of said sheet metal columns having, on its opposite ends, projections fitted in the corresponding positioning holes of said base and said top board for positioning each said sheet metal column with respect to said base and said top board,whereby each of said storage rack, said deck and said accessor-movement allowing means can be correctly positioned with respect to said plurality of frames.
