摘要： A plurality of light emitting elements comprise a number of groups having light emitting colors different from each other. The light emitting element groups are arranged in ring shapes about an optical axis of an optical system in a plane or planes substantially orthogonal to the optical axis. A combining unit combines radiation light beams of different light emitting colors to generate illumination light having a given hue. The combining unit is provided downstream of the light emitting elements along a light emitting direction. A focusing unit focuses the illumination light in the direction toward the optical axis and is provided downstream of the combining unit. Accordingly, it is possible to direct illumination light having uniform and non-irregular hue, the hue corresponding to a surface color of an object to be measured, to the object to be measured.

摘要： A light source (110) is fixed at a position and emits light in a direction away from an optical axis (A) of an objective lens. An outer reflecting mirror (an optical member) (130) and an inner reflecting mirror (an optical member) (140) are provided as a unit so that relative positions thereof are fixed. A reflecting mirror unit (120) can be moved in directions along the optical axis (A), i.e. up and down relative to the light source (110).

摘要： A photoelectric encoder that has a lens optical system including a lens inserted between a main scale and a light receiving element. In the photoelectric encoder, three planes extended from a surface of the main scale, a principal plane of the lens, and an image plane of the light receiving element are disposed so as to intersect at a single point and satisfy the Scheimpflug rule. Focus can thereby be obtained over the entire image plane, so that a reduction in contrast is prevented, even if the optical axis is inclined to make an optical system smaller.

摘要： A method for separating large-sized film-like plastics, such as polypropylene or polyvinyl chloride, which comprises placing the plastics in a separation tank containing an aqueous liquid medium and introducing gas bubbles into the tank thereby to cause the gas bubbles to adhere to the surface of the plastics. The buoyancy of the gas bubbles causes the plastics to rise to the medium surface. Addition of a flotation agent and/or a wetting agent further promotes the floating of the plastics.
