Abstract

PURPOSE:To avoid the mistake at the preset time by detecting the coincidence of the contents between the scanning counter and the memory memorizing the channel- selected address and then lighting up the display element corresponding to the coincidence detection signal. CONSTITUTION:The channel-selected address of channel selection switches S1-Sn is memorized in memory 26, and the contents are supplied to multiplexer 31. At the same time, the switch signal sent from signal production circuit 34 is supplied to multiplexer 31, and the contents of memory 26 are drawn out in sequence in the time-division way. Then the output of multiplexer 31 is supplied to coincidence detector circuit 32, and furthermore the value of scanning counter 21 is supplied to circuit 32. When the coincidence is obtained for the output between multiplexer 31 and counter 21, the detection output is supplied to multiplexer 33. At the same time, the switch signal sent from circuit 34 is supplied to multiplexer 33. And multiplexer 33 is switched in synchronization with multiplexer 31. With the output of multiplexer 33, display elements L1-Ln are lit up.
