英文摘要	PURPOSE:To replace a laser projector body without putting an optical axis out of order when it is used as a visual sensor, by providing a distance adjusting mechanism in the optical axis direction between a semiconductor laser and a rod-like microlens, and a position adjusting mechanism of the semiconductor laser. CONSTITUTION:A fixing plate 3 to which a semiconductor laser 1 is fixed is clamped temporarily to a lens fixing part 5 by utilizing a hole 9 by a screw 8 passing through a coil spring 7, the fixing plate 3 is moved within a range of a tolerance of the hole 9 so that the center of a cross line for showing an optical axis on a laser light detecting fluorescent plate 13 placed at a prescribed distance L from a laser projector body 10 coincides with the center of a laser light 12, and a laser position is adjusted on the surface falling at a right angle with an optical axis 1 Also, the optical axis 11 is made to coincide with an optical axis of a rod-like microlens 4. The screw 8 is clamped gradually so that a beam diameter D of the laser light 12 becomes a prescribed size, and a distance between the semiconductor laser 1 and the rod-like microlens 4 is adjusted.
