A data imprinting device for camera is provided with a shaft that rotatably supports the sprocket which is rotated as a film is fed, a light emitting device that emits a plurality of light beams, and an optical system for converging the light beams on the film. The light emitting device is provided to the shaft. The light emitting device is provided at the top of the shaft, and an optical path is defined inside the shaft, along its central axis, from the light emitting device. The optical path is bent at the lower portion of the shaft such that the light beams are incident on the film, via an opening formed on the shaft, to form beam spots arranged in a width direction of the film.
