  • Publication number: 20240049962
    Abstract: An ophthalmic apparatus includes an objective lens, an illumination optical system, an imaging optical system, and an optical path coupling member. The illumination optical system may illuminate a subject's eye with illumination light via the objective lens. The imaging optical system may guide returning light of the illumination light from the subject's eye to an imaging device via the objective lens. The optical path coupling member has a transparent member with a reflective region formed by evaporating a reflective film onto a part of a transmission region of its surface, and is configured to couple an optical path of the illumination optical system with an optical path of the imaging optical system. The transmission region may be arranged substantially conjugate optically to a subject's iris. The illumination light is reflected on the reflective region and the returning light is transmitted through the transmission region.

  • Publication number: 20230014194
    Abstract: An ophthalmic apparatus includes an illumination optical system that generates slit-shaped illumination light using a first light source; an optical scanner that deflects the illumination light to a fundus of a subject's eye; an imaging optical system that captures light from the fundus using a rolling shutter method; an acquisition unit that acquires a fundus image of the subject's eye using light from a second light source; a flare determination unit that determines whether or not flare occurs by analyzing the fundus image; a controller that performs flare optimization control by controlling at least one of the first light source, the illumination optical system, the optical scanner, the imaging optical system, and the image sensor based on a first determination result obtained by the flare determination unit; and an image forming unit that forms an image of the fundus when the flare does not occur.

  • Patent number: 9488835
    Abstract: A head-up display makes an observer visually recognize an image, which is optically reflected by a combiner, as a virtual image. The head-up display has a main body unit and an attaching unit. The main unit has a light source which is a projection unit for projecting the image. The attachment unit is configured such that the attachment unit can be attached to a sun visor that is provided to a vehicle. The joint member has a rotation shaft that rotatably joints the main unit to the attachment unit. The damper reduces vibration of the main unit in the rotational direction of the rotation shaft. When the rotation shaft of the joint member is attached to the sun visor by the attachment unit, the rotation shaft is substantially parallel to a sun visor supporting shaft so the sun visor can rotate in the direction in which the sun visor opens/closes.

  • Publication number: 20070192778
    Abstract: For providing a recording medium playback apparatus, which can prevent that clamping a recording medium in playback is unlocked, a CD changer includes a movable frame 66, a clamp unit 67, a pick-up unit 69, a lock unit 70 and a clamp lock/unlock unit 71. The movable frame 66 is movable against a main body. The clamp unit 67 is arranged on the movable frame 66 and clamps a CD 2. The pick-up unit 69 can move freely between a unclamp position to move close to the clamp unit 67 so as to unlock clamping of the clamp unit 67 and a playback position apart from the unclamp position more than the clamp unit 67. The lock unit 70 can move freely between a unlock position to make the movable frame 66 movable and a lock position to fix the movable frame 66. The clamp lock/unlock unit 71 in the unlock position limits the pick-up unit 69 to move close to the clamp unit 67 until the unclamp position.

  • Patent number: 6907611
    Abstract: A clamp mechanism comprises a turntable, a plurality of chuck claws, and a driving element. The turntable is rotatably driven by a motor. A disc serving as a recording medium is placed on the turntable. The chuck claws are used to hold, that is, clamp the disc on the turntable. The driving element drives the chuck claws both in both a first direction determined to clamp the disc and a second direction determined to unclamp the disc. The driving element includes a pressing portion so that travel of the chuck claws in the first direction in cases where the chuck claws are driven in the second direction. This offers stable clamping and unclamping operations of the chuck claws to detachably hold the disc on the turntable, independently of which attitude the disc takes.
