の双安定マルチバイブレータの負荷作動用出力を
遮断することを特徴とした双方向移動検出装置。 A sensor 1 in which the order of outputting signals from two output terminals differs depending on the moving direction of the infrared radiation source, and a pulse A that is generated first when the order of outputting signals is in a predetermined direction.
a bistable multivibrator 12 that continuously generates an output for operating the load 14 according to the rising edge of the bistable multivibrator 12;
It consists of an AND circuit 19 which inputs an H signal generated by the pulse B generated first when the signal output order is in the reverse direction, and an H signal generated by the falling signal UA of the pulse generated subsequently, The output signal of the AND circuit is applied to the bistable multivibrator 1.
A bidirectional movement detection device characterized in that an output for operating a load of this bistable multivibrator is cut off by inputting an input to a clear terminal CL of No. 2.
