DEFLECTOR, OPTICAL SCANNER, AND SCANNING DISTANCE MEASURING EQUIPMENT

摘要

Scanning distance measuring equipment includes a light emitter/receiver and a deflector for deflecting and reflecting measurement light emitted from the light emitter/receiver to outside through an optical window. The deflector is provided with a first deflection mechanism including a movable unit swingable about a first axis and a drive unit for driving to swing the movable unit; a second deflection mechanism for driving to rotate the first deflection mechanism about a second axis perpendicular to the first axis; and a contactless power supply unit including a second coil that is located to rotate about the second axis along with the rotating second deflection mechanism, and a first coil that is located to face the second coil on a common axis.
