IPC: G01V8/20
Filed: 2001-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a transmission photoelectric switch, which is asynchronous but can make a high-speed response. SOLUTION: When a stop signal is not received from a high-order gate means G in a step S21, each of gate means G opens a gate and is turned into 'standby state'. When a light receiving signal from a light receiving circuit 14 is received in a step S22, the gate is closed and it is judged whether or not set period information CH[0] is received from the high-order gate means G. When the information is not received, the gate is opened in a period T[0] (steps S23 and S24) and when the light receiving signal from the light receiving circuit is received in a step S25, the set period information CH[0] is applied to the low-order gate means G.  Afterwards, synchronous light receiving operation is performed in that period T[0], and a synchronous light receiving operation notice signal is synchronously applied to a synchronism extracting means 21 and an interference detecting means 22 as occasion demands (step S26). Afterwards, synchronous light receiving operation synchronized to each of light projecting from any light projector is performed by similar processing in order from the high-order gate means G1 so that each of gate means can find out light receiving signals projected in different periods from the respective light projectors.
