Abstract

PURPOSE: To enable to convert the output code of some counter circuits having the number of different counts into the code for display unit drive, by adding a detection section of simple constitution and correcting circuit section to a code conversion section.
CONSTITUTION: A detection section consists of an NAND gate 10 of so-called C2MOS type in which binary count output codes Q1WQ4 in 4 bit output from duodecimal binary counter circuit 30 are parallelly supplied, inverter 11, and P- MOS type transistor Tr12, and to the gate of Tr12, the signal inverting the conversion change-over signal TD outputted from a decimal binary counter circuit 40 in which the binary count output code is made to "1" in code conversion and while the output code from the circuit 30 is converted into "0", is fed. Thus, by inputting the signals α and -α outputted from the detection section to the correction circuit, the codes Q1WQ4 respectively outputted from the circuits 30 and 40 can be converted to the code for display unit drive.
