Patent number: 5936918Abstract: A direct entry/exit (DEE) door exposes several cells in the cell drum when the door is open. The DEE door is provided so that several storage media can be placed in or removed from the cell drum at once, either manually or automatically. The library apparatus automatically rearranges the storage media to fill the cells nearest the drive, which reduces the time required to locate storage media in the cell drum and place them in the drive. A locking mechanism locks the DEE door when the cell drum rotates, and locks the cell drum when the DEE door is open. Each cell in the cell drum has a skew mounting preventing mechanism and inverse mounting preventing mechanism which prevent incorrect mounting of a cartridge in the cell drum.Type: GrantFiled: May 14, 1997Date of Patent: August 10, 1999Assignees: Fujitsu Limited, Fujitsu Peripherals LimitedInventors: Yoshifumi Ohba, Manabu Kobayashi, Kenji Nakajima, Masayoshi Tanaka, Tsuyoshi Miura, Kazuyuki Mikawa

Patent number: 5878270Abstract: In a library apparatus, a transport device for transporting a medium to a drive unit and inserting the medium into the drive unit has a function of issuing, via a SCSI bus, a command to devices connected to the SCSI bus. Upon the power-on, the initiator function issues an inquiry command to the devices connected to the SCSI bus so that the number and types of the drive units installed in the library apparatus can be recognized based on inquiry data sent by the devices. In accordance with the number and types of the drive units installed in the library apparatus recognized, the transport device is controlled to properly transport the medium to the drive unit and insert the medium into the drive unit.Type: GrantFiled: June 25, 1996Date of Patent: March 2, 1999Assignee: Fujitsu LimitedInventor: Manabu Kobayashi

Patent number: 5757738Abstract: A library apparatus for storage media such as optical disks includes a rotatable cell drum having several columns of cells for storing the storage media, a load/unload device for inserting and removing cartridges one at a time, at least one drive for reading from or writing to selected media, and an accessor which moves the storage media between the load/unload device and the cell drum, and between the cell drum and the drive. The load/unload device rotates in a collinear arrangement with the cell drum, and can rotate in unison with the cell drum, or independently of the cell drum. The collinear arrangement of the cell drum and the load/unload device reduces the overall size of the library.Type: GrantFiled: July 12, 1995Date of Patent: May 26, 1998Assignees: Fujitsu Limited, Fujitsu Peripherals LimitedInventors: Yoshifumi Ohba, Manabu Kobayashi, Kenji Nakajima, Masayoshi Tanaka, Tsuyoshi Miura, Kazuyuki Mikawa, Masaaki Hashizume, Koji Yasuda
