Electronic flash apparatus of a camera

摘要

An electronic flash apparatus of a camera incorporating a focal plane shutter has a capacitor for storing an electric charge, a flashtube for irradiating a subject with a flash of light by the electric charge stored in the capacitor and a setting unit capable of setting any of a signal flash mode in which the flashtube effects a single flash and a high-speed mode in which the flashtube effects high-speed repetitive flash. The apparatus has a voltage setting unit for setting a first voltage as an energizing voltage when the single flash mode is set and setting a second voltage higher than the first voltage as an energizing voltage when the high-speed mode is set and an energizing unit for monitoring a voltage when the capacitor stores the electric charge and energizing a ready light just when the voltage in the storage of the electric charge exceeds the set energizing voltage.
