Publication number: 20020160808Abstract: Either a first memory card (13) for storing subscriber's information indispensable for communication, such as information on contract with a communication carrier or information to identify the user as a subscriber or a second memory card (15) for mainly storing application programs is selectively connected to a mobile radio apparatus. When the second memory card is installed, a main control unit (16) transfers the subscriber's information stored in the first memory card to the second memory card. Based on the subscriber's information, the main control unit receives the incoming call signal from a base station and informs notice of an incoming call. To speak by telephone, the second memory card is replaced with the first memory card, which makes it possible to talk over the telephone. Therefore, it is possible to provide an expandable mobile radio apparatus that enables functions to be added at the user's request.Type: ApplicationFiled: August 27, 2001Publication date: October 31, 2002Inventors: Keiji Uehara, Toshiaki Takaoka, Koichi Ito

Patent number: 5375115Abstract: An optical disk apparatus in which a head is accommodated in a movable part which moves the head along a guide shaft in a radial direction of an optical disk. The guide shaft is engageable with the movable part and extends in the radial direction of the optical disk. The optical disk apparatus has a guide shaft compression mechanism which applies a compression force toward the movable part, which force is distributed, approximately uniformly, along the radial direction of the optical disk, to the guide shaft so that the movable part can be properly engaged with the guide shaft so as to move smoothly and stably along the guide shaft in the radial direction of the optical disk.Type: GrantFiled: November 24, 1993Date of Patent: December 20, 1994Assignees: Mitsubishi Electric Corporation, Teac CorporationInventors: Hiroo Shimegi, Hidemitsu Fujisawa, Manabu Ogura, Yutaka Hashioka, Kazuhito Sakota, Masayuki Suzuki, Keiji Uehara, Yoshiki Kirinoe, Yasushi Noda

Patent number: 5278819Abstract: A disk storage device includes a head part which writes data into a storage disk loaded into the disk storage device and reads data from the storage disk, a linear actuator moving the head part in radial directions of the storage disk, an eject member which is operated when the storage disk is ejected, and a movement mechanism which moves the storage disk to an eject portion in response to an operation of the eject member and which moves the storage disk to a read/write position. A lock part, which has a lock member cooperating with the movement mechanism, keeps, in response to the operation of the eject member, the head part stationary at the eject position by the lock member which engages with one of the head part and the linear actuator.Type: GrantFiled: January 10, 1992Date of Patent: January 11, 1994Assignee: Mitsubishi Electric Corp and Teac Corp.Inventors: Hiroo Shimegi, Hidemitsu Fujisawa, Manabu Ogura, Yutaka Hashioka, Kuzuhito Sakota, Masayuki Suzuki, Keiji Uehara, Yoshiki Kirinoe, Yasushi Noda

Patent number: 5164935Abstract: A magneto-optical disk storage has an erroneous insertion preventing mechanism which projects into a holder so that it can touch the magneto-optical disk cartridge in order to prevent the same from being inserted. The erroneous insertion preventing mechanism mechanically engages with the magneto-optical disk cartridge and moves in a direction approximately vertical to the recording suface of the magneto-optical disk to allow the magneto-optical disk cartridge to be inserted only if the magneto-optical disk cartridge is being inserted into the holder with a correct orientation.Type: GrantFiled: June 13, 1991Date of Patent: November 17, 1992Assignees: Mitsubishi Electric Company, Teac CorporationInventors: Hiroo Shimegi, Hidemitsu Fujisawa, Manabu Ogura, Keiji Uehara, Masayuki Suzuki, Yoshiki Kirinoe, Yasushi Noda

Patent number: 5088085Abstract: A magneto-optic disk unit includes a cartridge holder having an insertion opening, an inside surface and first and second surfaces, an erroneous insertion preventing mechanism having at one end a stopper portion for prohibiting erroneous insertion of a magnetic disk cartridge and at the other end an insertion detecting portion for detecting insertion of a magnetic-optic disk cartridge, and a supporting mechanism for rotatably supporting the erroneous insertion preventing mechanism. The insertion detecting portion projects inside of the cartridge holder from an upper surface of the cartridge holder, so that when the magneto-optic disk cartridge is inserted the insertion detecting portion moves outside of the cartridge holder to allow insertion of the magneto-optic disk cartridge, and that when the magnetic disk cartridge is inserted the insertion detecting portion does not substantially move, thus permitting the stopper portion to prevent insertion of the magnetic disk cartridge.Type: GrantFiled: April 20, 1990Date of Patent: February 11, 1992Assignee: Teac CorporationInventor: Keiji Uehara
