Abstract
A camera includes a camera body, a flash unit which is movable between a first position where it is accommodated in the camera body and a second position where it is protruding from the camera body, and a toggle mechanism designed to change a direction of a biasing force between the camera body and the flash unit in response to the movement of the flash unit relative to the camera body.
