Abstract
A digital display apparatus for indicating a cooking time and power of an electric cooking device by means of common digital indicators, wherein a first group of AND gates is connected between a first shift register for storing a cooking time data and digital indicators, and a second group of AND gates is connected between a second shift register for storing a power level setting data and digital indicators. Depression of a function key for use in a cooking time data setting enables the first group of AND gates and disables the second group of AND gates to cause the common digital indicators to indicate the cooking time data stored in the first shift register, and depression of a function key for use in power level data setting enables the second group of AND gates and disables the first group of AND gates to cause the common digital indicators to indicate power level setting data stored in the second shift register.
