Patent number: 11067382Abstract: A three-dimensional coordinate measurement apparatus capable of reducing shaking of a Y carriage and improving measurement accuracy. The Y carriage is supported by two strut members which are across a surface plate and movable in a Y-axis direction. The two strut members include a first strut member having a driving mechanism and a second strut member which moves following the first strut member. A guide portion parallel to the Y-axis direction is formed in the surface plate on a first strut member side. Side surface support members support the first strut member on the surface plate by holding both opposed side surfaces of the guide portion. The driving mechanism includes a roller having an axis perpendicular to a surface plate surface, and the roller is brought into contact with one side surface of the guide portion and rolled to move the Y carriage relatively to the surface plate.Type: GrantFiled: December 20, 2019Date of Patent: July 20, 2021Assignee: Tokyo Seimitsu Co., Ltd.Inventors: Yukio Kanno, Keiichiro Gomi, Takashi Fujita

Patent number: 9921049Abstract: There is provided a three-dimensional coordinate measurement apparatus capable of reducing shaking of a Y carriage and improving measurement accuracy. A groove is formed along a Y-axis direction in a right side part of a surface plate made of stone, and a Y guide is formed between the groove and a right side surface of the surface plate to support a Y carriage in a portal shape in a movable manner in the Y-axis direction. A support section is provided at a lower end of a right Y carriage on the right side of the Y carriage, and the support section is supported by the surface plate through air pads which are disposed by two air pads back and forth on the corresponding one of a top surface, a right side surface, and a bottom surface, of the surface plate, and a right side surface of the groove.Type: GrantFiled: July 27, 2017Date of Patent: March 20, 2018Assignee: Tokyo Seimitsu Co., Ltd.Inventors: Yukio Kanno, Keiichiro Gomi, Takashi Fujita
