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.
其他摘要	用途：通过在半导体激光器和杆状微透镜之间的光轴方向上提供距离调节机构，以及位置，在不用光轴作为视觉传感器的情况下更换激光投影仪机身时调整半导体激光器的机理。组成：固定半导体激光器1的固定板3通过穿过螺旋弹簧7的螺钉8利用孔9临时夹紧到镜头固定部分5，固定板3在一个范围内移动。孔9的公差使得用于显示位于距激光投影仪主体10的规定距离L的激光检测荧光板13上的光轴的交叉线的中心与激光12的中心一致，并且在与光轴11成直角的表面上调节激光位置。另外，使光轴11与棒状微透镜4的光轴一致。螺钉8被逐渐夹紧以便光束激光12的直径D变为规定尺寸，并调节半导体激光器1和棒状微透镜4之间的距离。
