Abstract: A reference core position calculation device 100 that calculates a reference core position of an elevator shaft in which an elevator is to be installed includes a measurement unit 101 and a calculation unit 112. The measurement unit 101 measures a dimension of each portion of the elevator shaft. The calculation unit 112 calculates portion dimension values of the elevator shaft based on the reference core position and the dimension of each portion measured by the measurement unit 101. When the reference core position is a first reference core position, the calculation unit 112 determines whether portion dimension values of the elevator shaft calculated based on the first reference core position satisfy a predetermined specification.

Abstract: A lens barrel detachably attached to a camera body includes a fixed tube section that has a base end installed at the camera body, and a top end, a first pitch screw section being formed on an inner peripheral surface of the top end; a movable tube section that is a tube member configured to hold a plurality of lens and has a second pitch screw section on the movable tube side formed at an outer peripheral surface, and is located so as to be movable inside the fixed tube section in such a state that the second pitch screw section is threadedly engaged with the first pitch screw section, the plurality of lens including two group of lenses, a first group and a second group, held within the movable tube section. The movable tube section having a fixed diaphragm plate that is detachable.

Abstract: [Problem] To make it possible to prevent vibrations or the like from causing focus or zoom slippage or the like in a lens that is mounted to a camera body that is used in a fixed location outdoors for many years for security purposes or is used inside a building that is subject to a variety of variations, such as a camera that is used for quality-checking purposes or the like at a production site in a factory. [Solution] The lens barrel (1) in this invention has the following: a fixed tube section (10) that is mounted to a camera body (B); a movable tube section (20) that is movably screwed to the fixed tube section (10); and a nut member (12) that, screwed to the movable tube section (20), is energized towards top end (10b) of the fixed tube section (10). The nut member (12) acts as a double nut, making it possible to inhibit rotation of the fixed tube section (10) and the movable tube section (20) relative to each other, preventing focus or zoom slippage or the like.
