Publication number: 20130265662Abstract: An attachment structure is configured to attach a first member to a second member. The attachment structure includes a first engagement portion which is provided at one of the first member or the second member, and a second engagement portion which is provided at the other one of the first member or the second member and which engages with the first engagement portion at a predetermined attachment position to restrict a relative movement. One of the first member or the second member at which the second engagement portion is provided, is provided with spaces at both sides of the second engagement portion in the circumferential direction. The first member and the second member include a torque change portion which changes a torque such that the torque is larger at a preceding side and a succeeding side of the attachment position in the circumferential direction, than at the attachment position.Type: ApplicationFiled: January 4, 2013Publication date: October 10, 2013Applicant: PANASONIC CORPORATIONInventors: Keiji ARAIE, Akio KONISHI

Publication number: 20130265663Abstract: The adapter correcting for glass thickness includes an adapter main body, a plane parallel plate, and a retainer. The adapter main body includes an attacher/detacher capable of attaching and detaching with respect to an adapter connecter on the lens barrel; a tubular accommodator extending from the attacher/detacher toward the objective along an optical axis of the field lens; and a tongue provided on the attacher/detacher side of the accommodator. The plane parallel plate includes two mutually parallel flat surfaces and is inserted into the accommodator such that the two flat surfaces are orthogonal to the optical axis of the field lens. The retainer is attached to an end of the accommodator closest to the objective and holds the plane parallel plate between the retainer and the tongue. The accommodator is formed to have a tubular length sufficient to insert at least two plane parallel plates.Type: ApplicationFiled: March 15, 2013Publication date: October 10, 2013Applicant: MITUTOYO CORPORATIONInventor: Hidekazu SANO
