Abstract
In the disclosed camera a sound-making element is provided to produce warning signals or confirming signals for operation of a self-timer. A binary counter which digitally controls the camera controls the sound-making element. Warning signals and confirming signals for operation of a self-timer are distinguished from each other by a difference in oscillation pulses.
