A laser scanner comprises: multiple laser light sources (101, 102, 103); prisms (301, 302) for changing the direction of laser light entering from respective laser light sources to a direction of a converging optical axis; an aperture (53) provided so as to be adjustable in a prescribed direction of adjustment for the laser light emitted from the prisms; and a scanning mirror (500) for reflecting the laser light entering through the aperture from the prisms toward a scanning position. The multiple laser light sources are provided such that when the laser light emitted from each laser light source enters the aperture, the long axis in the light intensity distribution of the laser light is oriented in the prescribed direction of adjustment. |
