Abstract
There is provided a security sensor device having an optical axis adjusting capability, which device includes a beam projecting unit () for projecting sensing waves, to which ID codes for specifying beam projectors () are applied, to a beam receiving unit () sequentially at predetermined intervals. The beam receiving unit () detects the level of light received by each of beam receivers () corresponding to or identified by the respective ID codes and transmits the received light levels to the beam projecting unit (). According to these features, during the optical axis adjustment the levels of light received by the beam receivers () can readily be obtained on the side of the beam projecting unit (), resulting in an accurate adjustment of optical axis between the beam projectors () and the beam receivers () in a short length of time with a simplified structure.
