A projector for use in a measuring device is provided with an emitter which emits a beam of visible light to a measurement object along a predetermined optical axis, a rotary optical member which is operable to change the propagation direction of the visible light beam with respect to the predetermined optical axis in accordance with rotation of the rotary optical member, and a driver which rotates the rotary optical member about a rotation axis. The projector accurately indicates a measurement area on a measurement object in simpler construction.
