Abstract
PURPOSE:To make it possible to decide accurately on the position of a pole to which a photo switch is connected at a reception side, by applying a reference level signal to one pole of the photo switch. CONSTITUTION:Data measured at several points are converted by optoelectro converter circuits 1-5 into photo signals, which are supplied to respective poles (a)- (e) of photo switch 13. Here, a reference photo signal for a level higher than photo levels of poles (a)-(e) of photo switch 13 is supplied to 6th pole (f). A reception part detects this reference photo level and regards this as a synchronizing signal to discriminate the position of switch 13.
