To enable a photographer to well take pictures, using simple operation.

When a lens cover is operated to slide to a fully open state, a main switch 26 shifts to an on state in cooperation with this operation, and an oscillation circuit 32 oscillates to impress a high voltage of AC to a main capacitor Cm and charges this capacitor. If the incident light on an optical sensor Q3 is lower than prescribed intensity, a transistor(TR) Q2 remains off and a trigger capacitor Ct is charged as well. When a shutter release button is depressed, the button is triggered by the charge of the trigger capacitor Ct and a stroboscopic light emitting tube Xe is lighted to emit light by a high- voltage from the main capacitor Cm, and stroboscopic photography is carried out. The incident light, however, is stronger than the prescribed intensity, the TR Q2 turns on and the trigger capacitor Ct will not be charged, and the stroboscopic light emitting tube Xe is not lighted to emit light, even if the shutter release button is depressed.
