Publication number: 20240096377Abstract: According to one embodiment, a disk device includes a housing, magnetic disks in the housing, and a printed circuit board attached to an outer surface of a bottom wall of the housing. The housing includes a base including a bottom wall and a side wall, and at least two base-side positioning portions provided on the bottom wall in a region overlapping the side wall. The printed circuit board includes at least two board-side positioning portions each engaged with the base-side positioning portion. One of the base-side positioning portion and the board-side positioning portion includes a pin extending substantially perpendicular to the bottom wall, and another includes a hole into which the pin is fitted.Type: ApplicationFiled: March 13, 2023Publication date: March 21, 2024Inventors: Hiroshi Minami, Shigeru Juman, Kouichi Toukairin, Yasuhiko Kato, Hirofumi Kuribara, Kenji Mizuochi

Publication number: 20090244784Abstract: A storage apparatus includes a magnetic circuit applying driving force to a carriage. The magnetic circuit includes a first yoke provided with a magnet. An end of the first yoke is secured using a first fastening member screwed in a threaded hole in an end of the base. A second yoke is opposed to the first yoke, and an end of the second yoke is secured using a second fastening member screwed in a threaded hole in another end of the base. A driving coil is held by the carriage and disposed between the first yoke and the second yoke so that the first yoke and the second yoke are attracted to each other by magnetic force of the magnet.Type: ApplicationFiled: March 25, 2009Publication date: October 1, 2009Applicant: FUJITSU LIMITEDInventor: Shigeru Juman

Patent number: 6738334Abstract: A miniaturized optical disc memory is receivable in a slot, of about 17 mm height, normally accommodating a floppy disc drive. A base includes a base plate with integral, peripheral sidewalls and an internal lateral partition wall which define a cartridge receiving slot on the upper surface of the base plate. First and second support plates extend from the partition wall to the rear peripheral sidewall of the base and define respective, first and second upper mounting surfaces and lower first and second cavities respectively receiving an ejection motor and a fixed optical system, individual optical components being mounted and aligned on integral, precision machined blocks in the second cavity for transmitting a laser beam and receiving a reflected beam along a central, longitudinal optical axis beneath the base plate.Type: GrantFiled: November 9, 2000Date of Patent: May 18, 2004Assignee: Fujitsu LimitedInventors: Hidenori Saitou, Toshitaka Iwamoto, Hirataka Ukai, Yasukiyo Kunimatsu, Shigeru Juman, Tomoo Sukagawa, Masateru Sasaki, Tatsutoshi Nagasaki, Masao Uchiyama

Patent number: 6567363Abstract: The present invention is intended to produce an optical disk drive unit, which is an optical data recording and reproducing apparatus, compactly and to improve the efficiency in assembling components of the drive unit. The optical disk drive unit consists of a driving mechanism and a printed wiring board. The driving mechanism assists in loading a cartridge, which accommodates an optical disk that is a commutative medium, in a main unit, drives the cartridge, and reads or writes data from or on the optical disk. A circuit for driving and controlling the driving mechanism is mounted on the printed wiring board. The driving mechanism can be divided into a load/ejection mechanism and a reading/writing mechanism. The load/ejection mechanism is a united body consisting of a cartridge identification sensor, an ejection motor for ejecting a cartridge, and a bias magnet assembly.Type: GrantFiled: March 30, 2000Date of Patent: May 20, 2003Assignee: Fujitsu LimitedInventors: Shigeru Juman, Soichi Shimura
