ABSTRACT:
A pop-up flash of a camera includes a flash unit movable between a retracted position, in which the flash unit is accommodated in a camera body, and a fully-lifted position, in which the flash unit projects from the camera body; a biasing device which biases the flash unit toward the fully-lifted position; and a speed-change mechanism for changing a speed of movement of the flash unit, which is driven by the biasing force of the biasing device, during movement of the flash unit in a projecting direction from the retracted position to the fully-lifted position.
