The recorder includes a receiving circuit, a Schmitt-Trigger circuit, a control comprising CPU, ROM, a clock and a printer circuit, and pulse generator. High frequency signals and channel signals from the receiving circuit are processed at the SchmittTrigger circuit and the pulse generator to be applied to the control, whose outputs are arranged to print out each bus-stop code number and time of start and arrival at respective stops.
