Publication number: 20230233079Abstract: An ophthalmologic apparatus includes: a head unit having an optical system capable of receiving light reflected from a subject's eye; a drive mechanism that movably holds the head unit; an alignment detection unit that detects a position of the subject's eye relative to the head unit; and a control unit that controls the drive mechanism. The drive mechanism includes at least two arms rotatably connected together, at least two first rotation support mechanisms and at least three second rotation support mechanisms which allow the head unit to move, and at least five driving units for driving the rotation support mechanisms. The control unit is capable of controlling the driving units using a measurement result of the alignment measuring unit to align the head unit and the subject's eye with each other.Type: ApplicationFiled: March 24, 2023Publication date: July 27, 2023Applicant: TOPCON CORPORATIONInventors: Shingo UENO, Ryousuke ITO

Patent number: 7909462Abstract: An opthalmologic apparatus has an examination unit including a plurality of examining parts for executing different examinations on an eye to and a driver moving the examination unit in the horizontal direction and in the anteroposterior direction. The opthalmologic apparatus controls the driver when switching a examination subject by the examination unit from one eye to the other eye to cause the examination unit to retreat by only a retreating distance according to the working distance of an examination part positioned at the examination position for the one eye. The examination unit retreats by only a distance according to the working distance. Therefore, it is possible to achieve both reductions in examination time and improvements for safety by preventing an examining part comes into contact with the patient.Type: GrantFiled: December 22, 2008Date of Patent: March 22, 2011Assignee: Kabushiki Kaisha TopconInventors: Yoshitsugu Takahashi, Ryousuke Ito

Patent number: 7841717Abstract: An opthalmologic apparatus having a setting part configured to acquire position information of a first examining part at the time of execution of a first examination and set a movable range of a second examining part in a direction of a second working distance based on the position information and distance information. This opthalmologic apparatus controls so that an examining unit moves within the movable range set based on the position information of the first examining part and the distance information when an examination by the examining unit is switched from the first examination to a second examination. Accordingly, it is possible to set an accurate movable range with respect to the position of the eye of a subject, and it is also possible to increase safety by preventing the examining part from coming in contact with the subject.Type: GrantFiled: February 9, 2009Date of Patent: November 30, 2010Assignee: Kabushiki Kaisha TopconInventors: Ryousuke Ito, Takeshi Nakamura
