Abstract
A signal transmission apparatus from a control unit to a plurality of memory units which correspond to signal terminal means and which are connected in series with each other, wherein the memory units at the starting end and at the final end are connected to the control unit to constitute a closed loop, wherein the memory unit at the starting end or the final end receives a gate signal and stores it temporarily to open a gate, and wherein the memory units transfer gate signals to the subsequent stages successively responsive to clock pulses, and having detector means which detects whether the first gate signal has circulated the closed loop constituted by the series connected memory units, and a switch which switches the sending path of the gate signal depending upon the detected result so that the gate signal is sent from the memory unit of either the starting end or the final end.
