アナログ・デジタル時計。 An analog/digital display clock having an analog display section that displays the time in analog form by driving hands, an additional function circuit having functions other than measuring the current time, and a digital display section displaying the output of the additional function circuit. , a current time counter that counts the current time in conjunction with the time displayed on the analog display section, a voltage detection circuit that detects at least two types of voltage values of the battery power supply, and a gate circuit that controls the operation of the analog display section. a matching circuit for detecting whether the time displayed on the analog display unit matches the current time counted by the current time counter; and a matching circuit for detecting whether the time displayed on the analog display unit matches the current time counted by the current time counter; a display switching circuit for selectively switching one of the output signals; and a display switching circuit for causing the gate circuit to stop the operation of the analog display section when the voltage detection circuit detects the lower of the two detection voltage values. A signal for selectively switching the signal of the current time counter is output to the display switching circuit, and then the voltage detection circuit detects the higher voltage value, and when a coincidence signal from the coincidence circuit is input, the analog display section operates. and a signal switching circuit that outputs a signal that causes the display switching circuit to select and switch the signal of the additional function circuit.
