Determining the accessibility of a portable storage device using format and access right information
Patent number: 7447835Abstract: There is provided a portable storage device which makes it possible to largely reduce time that is taken to remove the storage cartridge that is inserted and cannot be handled. A removable hard disk cartridge contains a hard disk and a control circuit for control of writing and reading of data in and from the hard disk in a casing thereof. A main unit includes an automatic loading/ejecting mechanism that receives the hard disk cartridge into a predetermined inner position within the main unit and ejects the same out from the position, and a microprocessor that controls storage operation for storing data in the hard disk cartridge. Before the automatic loading/ejecting mechanism performs a receiving operation, it is determined whether access to contents recorded on the hard disk can be gained, and when the access cannot be gained, the receiving operation by the automatic loading/ejecting mechanism is inhibited.Type: GrantFiled: July 27, 2006Date of Patent: November 4, 2008Assignee: Canon Kabushiki KaishaInventors: Masato Fujiwara, Masumi Ishiwatari, Takeyuki Higashibata, Tadashi Takayama, Noriyuki Suzuki, Hiroyasu Ito, Makoto Kobayashi, Mamoru Yoshimoto -

Publication number: 20080071795Abstract: An apparatus receives meta-information from a plurality of external apparatuses, and caches the received meta-information per external apparatus that is the origin of the meta-information. Then, the meta-information cached per external apparatus is consolidated, and display of the meta-information is managed. Based on this display management, display management information corresponding to the meta-information cached per external apparatus is obtained, and the external apparatus to which a request for the meta-information is to be made is selected based on the display management information and the cache status of the meta-information per external apparatus. Then, the meta-information is requested from the selected external device.Type: ApplicationFiled: September 10, 2007Publication date: March 20, 2008Applicant: CANON KABUSHIKI KAISHAInventor: Masato Fujiwara

Publication number: 20080051666Abstract: Without setting an examination site, it is possible to easily position an end face of a narrow-diameter end portion at a suitable position with respect to an examination target, allowing an image of the examination site to be acquired quickly and easily. The invention provides an objective-lens guiding device comprising a support portion secured to an objective lens having a narrow-diameter end portion; and a cylindrical portion for accommodating the narrow-diameter end portion. The support portion supports the cylindrical portion such that a front end of the cylindrical portion is disposed at a location farther toward the front than an end face of the narrow-diameter end portion, and so as to be capable of moving in an optical axis direction.Type: ApplicationFiled: August 20, 2007Publication date: February 28, 2008Inventors: Yasuaki Natori, Masato Fujiwara, Nobuhiko Onda, Tatsuya Okadome, Ikuko Sakai

Publication number: 20070255143Abstract: An imaging apparatus includes an illumination light source emitting illumination light, a small-diameter image-transmitting portion, a distal end of which is placed near a specimen, an objective lens converging the illumination light to a proximal end of the image-transmitting portion, a light-detecting portion that detects light returned from the specimen via the image-transmitting portion and the objective lens, and a shield portion partially blocking the illumination light, the shield portion being disposed at near a pupil position of the objective lens or near a position optically conjugate with the pupil position so as to cover the illumination light path on one side in a radial direction. With this configuration, a sharp image with low noise can be obtained by preventing the occurrence of reflection at the proximal end of the image-transmitting portion and also by avoiding autofluorescene from being produced.Type: ApplicationFiled: April 25, 2007Publication date: November 1, 2007Applicant: OLYMPUS CORPORATIONInventors: Ikutoshi Fukushima, Tadashi Hirata, Masato Fujiwara
