Abstract

PURPOSE:To obtain the simple constitution by connecting the light projector of an optical switch in the next stage so as to light up when the light receiver of a photoelectric switch receives light and forming the output terminal of a final stage light receiver at the detection output terminal of an obstacle detecting device, in the titled device installed at an inlet/outlet of a rotary shelf. CONSTITUTION:The light projector 161 of the first stage photoelectric switch 151 lights up at all times by the turning-ON of an electric power source, and the output terminal OP of a light receiver 171 conducts with an electric power source input terminal (n). Therefore, the light projector 162 of the photoelectric switch 152 in the next stage lights up through the light receiving device 171. Similarly, the light projectors of the photoelectric switches light up in succession, and the light projector 16n in the final stage lights up, and the output terminal OP of the light receiving device 17n conducts with the electric power source input terminal (n), and a detection signal output terminal OP conducts with an electric power source terminal N. Therefore, if any of the photoelectric switches is cut off by an obstacle, the light receiver 17n in turned-OFF, and the detection signal output terminal OP is turned-OFF. Thus, a simple constitution can be obtained.
