Abstract
A flash unit is slidable between a retracted position in a camera body and a pop-up position outside the body. A switch enables a flash exposure control in response to movement of the flash unit out of the camera body and disables the exposure control when the flash unit is moved into the camera body. An override switches the switch to the disabling position when the flash unit is moved outside of the body and forms a discharge circuit for the flash main capacitor.
