Abstract
There is described a strobe device to which another electronic circuit or electronic element is added, and a lens-fitted film unit and a camera, which incorporates the strobe device. The strobe device includes: a strobe light-emitting tube to emit a strobe light; a main-capacitor coupled in parallel to the strobe light-emitting tube, so as to supply a luminous energy to the strobe light-emitting tube; a trigger-transformer to apply a trigger-voltage to a trigger-electrode of the strobe light-emitting tube; a trigger-section to activate a light-emitting action of the strobe light-emitting tube; a trigger-capacitor, coupled to the main-capacitor with a resistor, to store an electronic charge, which is discharged to the trigger-transformer when the trigger-section turns ON; and a semiconductor element driven by a part of an electronic charge stored in the main-capacitor, when the trigger-section turns ON to activate the light-emitting action of the strobe light-emitting tube.
