Zusammenfassung:PURPOSE:To prevent the same contents from being displayed for a long time by displaying display information which is outputted by a code decoder and erasing the display contents with the erasure signal which is outputted by a retriggerable time circuit. CONSTITUTION:The display information which is outputted by the code decoder 2 is displayed and erased with the erasure signal which is outputted by the retriggerable timer circuit 4 unless a next trigger signal is inputted with a certain time after the trigger signal of the code decoder 2 is inputted. Consequently, even if trouble occurs on a center signal transmission line, old information of a public information display is erased to prevent the public from misunderstanding the display.
