  "textContent": "A head-up display device and a self-checking method therefor are provided, which are able to suppress the direct output of a laser beam to outside. A reflecting means (70) reflects an image generated by a scanning means (30) and projects the image outside of a case (80), and an angle-adjusting means (301) adjusts the reflecting means (70) to a desired angle. After the ignition switch of the vehicle is turned on, a light-emitting means (10) outputs a scanning laser beam, and the value of the current flowing to the light-emitting means (10) is detected, or a first light intensity, which is the light intensity of the scanning laser beam, is detected. For a period extending at least from the output of the scanning laser beam by the light-emitting means (10) to the establishment of a predetermined condition, the angle-adjusting means (301) is controlled such that the reflecting means (70) is set to a non-visible position at which the scanning laser beam is reflected inside the case (80).",
