Abstract
A photographing mode selecting circuit for a camera having a very low power consumption. A mechanical switch is provided for each possible photographing mode of the camera. Each mechanical switch is coupled in series with a resistor and an analog switch between the power source terminals. The analog switches are periodically pulsed to close them, thereby allowing current to flow through the corresponding resistor and mechanical switch if the mechanical switch is closed. The outputs formed at the junctions between the analog switches and the resistors are applied to flip-flop circuits for storage.
