Abstract
Abstract In a caseless camera, a cover plate having a contact member at the rear side thereof is slidably mounted at the front side of a camera body between its closing and opening positions. An electric flash mounted inside the camera body traversely movably between its restoring and operating positions is provided with an inclined step at the front side thereof. The contact member of the cover plate contacts and downwardly push the inclined step of the electric flash so as to return the electric flash to its restoring position, when the electric flash is in its operating position, upon the sliding movement of the cover plate from its opening positions to its closing position.
