<p>An image drawing device, comprising: a first light source; a second light source; a scanning means that scans the light emitted from the first light source and the second light source and causes an image to be drawn on a drawing target; an optical axis displacement detection means that detects the displacement of optical axes of the light that has been emitted from the first light source and the second light source, and which has not been scanned by the scanning means; an optical axis correction means that corrects such that the optical axes of the light emitted from the first light source and the second light source match; and a light-shielding means that blocks the optical path between the first and second light sources and the scanning means during the detection operation by the optical axis displacement detection means.</p> |
